Description

The embodiments disclosed in this specification and drawings relate to a sample testing device and a sample testing system.

Sample testing devices are known that perform tests to detect target substances contained in samples. The target substances are collected, for example, from bodily fluids such as nasal mucus. Examples of target substances include adenovirus and influenza virus. For example, by using multiple sample testing devices, a variety of tests can be performed. Sample testing devices are equipped with input/output devices, which, for example, perform various inputs and display and print test results. For example, when multiple tests are performed separately on multiple devices, input and printing are performed on each device, which is inefficient. Therefore, if sample testing devices are centrally managed using master and slave devices, testing efficiency is expected to improve.

Embodiments of the sample testing device and sample testing system will be described in detail below with reference to the accompanying drawings. Note that the embodiments are not limited to the following embodiments. Furthermore, in principle, the content described in one embodiment also applies to other embodiments.

Figure 1 shows an example of a sample testing system 1 to which a sample testing apparatus 10 according to this embodiment is applied. As shown in Figure 1, the sample testing system 1 includes multiple sample testing apparatuses 10 and a biological reaction device 2.

The biological reaction device 2 is used to perform a test to detect a target substance contained in a sample (for example, a body fluid component such as a runny nose). Details of the biological reaction device 2 will be described later. The biological reaction device 2 is an example of a "device."

As shown in FIG. 1, the sample testing device 10 includes a cover 20, a main body 30, and an indicator 35.

The cover 20 is provided so as to be openable and closable relative to the specimen testing apparatus 10. Specifically, the main body 30 is provided with a stand for mounting the biological reaction device 2, and the cover 20 is provided to cover this stand. For example, when performing a test to detect a detection target, the biological reaction device 2 is mounted on the stand of the main body 30, and the stand is covered by the cover 20. Here, the example shows a case in which the cover 20 is provided so as to be openable and closable relative to the specimen testing apparatus 10, but it may also be provided so as to be detachable relative to the specimen testing apparatus 10.

The indicator 35 is provided on the front surface of the main body 30. The indicator 35 will be described later.

In FIG. 1, the multiple specimen testing devices 10 are composed of, for example, specimen testing devices 10A, 10B, and 10C. Of the specimen testing devices 10A, 10B, and 10C, specimen testing device 10A is the master specimen testing device 10, and specimen testing devices 10B and 10C are slave specimen testing devices 10. Specimen testing device 10A is communicably connected to specimen testing devices 10B and 10C via a network. Specimen testing devices 10A, 10B, and 10C are connected to, for example, an in-hospital LAN (Local Area Network) installed in a hospital or the like, and send and receive information. For example, specimen testing devices 10B and 10C are assumed to have been additionally purchased and installed in the testing room where specimen testing device 10A is installed.

As shown in FIG. 1, the master specimen testing device 10, specimen testing device 10A, is provided with an input/output device 40. The input/output device 40 is expensive because it includes a display and printer, which will be described later. For this reason, from a cost perspective, it is preferable not to provide the input/output device 40 in the slave specimen testing devices 10, specimen testing devices 10B and 10C. The input/output device 40 is an example of an "input/output unit."

Next, we will explain the biological reaction device 2 that is attached to the base of the main body 30 of the sample testing apparatus 10. Figure 2 is a diagram showing an example of the configuration of the biological reaction device 2 shown in Figure 1.

As shown in FIG. 2, the biological reaction device 2 is placed on the mounting table 4, which is the base of the main body 30, and has a housing 21, a transparent substrate 22, an optical waveguide 23, and a protective member 24. A portion of the underside of the housing 21 is open, and a chip in which the optical waveguide 23 and protective member 24 are formed on the transparent substrate 22 using thin-film technology is fitted into the opening. A portion of the protective member 24 is open (opening edge 24a). The housing 21, optical waveguide 23, protective member 24, etc. form a reaction vessel 201. The biological reaction device 2 is configured to be able to hold a sample solution containing a test subject (test substance) inside, i.e., in the reaction vessel 201.

The housing 21 is made of, for example, resin. A first recess is formed in the bottom surface of the housing 21. A second recess is formed in part of the top surface of the first recess, constituting the top and side surfaces of the reaction vessel 201. A protective member 24, an optical waveguide 23, and a transparent substrate 22 are arranged in the first recess, from top to bottom. A hole 21a is formed near one end of the top surface of the second recess, penetrating upward through the housing 21 to introduce a sample solution, reagent, etc. into the reaction vessel 201 inside, and a hole 21b is formed near the other end, penetrating upward through the housing 21 to allow air to escape from the reaction vessel 201. Note that multiple holes 21a and holes 21b may be formed.

The transparent substrate 22 is formed of, for example, resin or optical glass. The transparent substrate 22 passes light incident from the light source 311 provided in the main body 30 to the optical waveguide 23. The transparent substrate 22 also passes light incident from the optical waveguide 23 to the photodetector 312 provided in the main body 30.

The optical waveguide 23 is formed from a light-transmitting material, such as resin or optical glass. Examples of resins that can be used include phenolic resin, epoxy resin, and acrylic resin. The optical waveguide 23 serves as an optical path for light that enters the transparent substrate 22 and exits the transparent substrate 22. In other words, the optical waveguide 23 functions similarly to the core of an optical fiber. The protective member 24 and transparent substrate 22 are formed from materials with a different refractive index than the material of the optical waveguide 23, and function as a cladding that totally reflects light at the interface with the optical waveguide 23 and confines the light within the optical waveguide 23. The protective member 24 and transparent substrate 22 also physically protect the optical waveguide 23.

The optical waveguide 23 propagates light incident from the main body 30 through the transparent substrate 22. The optical waveguide 23 propagates light that is affected by the concentration of the test substance contained in the reaction vessel 201, i.e., the reaction state.

A grating 23a is also arranged on the protective member 24 side near where light enters the optical waveguide 23. The grating 23a diffracts the incident light L1 entering the optical waveguide 23 at a predetermined angle. The light diffracted by the grating 23a is incident on the interface between the optical waveguide 23 and the surface formed by the transparent substrate 22, the protective member 24, or the mixed liquid 202 at an angle equal to or less than the supplementary angle of the critical angle. As a result, the incident light L1 propagates (waveguided) within the optical waveguide 23 while being repeatedly reflected at the interfaces of the optical waveguide 23.

A grating 23b is arranged on the protective member 24 side near where light exits the optical waveguide 23. The grating 23b diffracts the light guided by the optical waveguide 23 at a predetermined angle. The light diffracted by the grating 23b is emitted from the optical waveguide 23 to the outside at a predetermined angle.

The protective member 24 has an opening at the position of the second recess in the housing 21. The protective member 24 is placed in close contact with the upper surface of the optical waveguide 23. By being placed in close contact with the upper surface of the optical waveguide 23, the protective member 24 forms a planar protective layer. As shown in FIG. 2, the protective member 24 also has an opening edge 24a for exposing the main surface (e.g., the upper surface) of the optical waveguide 23. The opening edge 24a is a vertical surface that forms an opening inside the protective member 24. The upper surface of the optical waveguide 23 is exposed by this opening edge 24a.

The reaction vessel 201 has an upper surface formed by the upper surface of the second recess of the housing 21, a side surface formed by the side surface of the second recess of the housing 21 and the open end 24a of the protective member 24, and a lower surface formed by the upper surface of the optical waveguide 23.

The reaction vessel 201 contains a sample solution and a reagent, and reacts the test substance contained in the sample solution with the reagent. A plurality of first antibodies 211 are immobilized on the lower surface of the reaction vessel 201, i.e., the upper surface of the optical waveguide 23. The first antibodies 211 are substances that react specifically with antigens 212 contained in the test substance through an antigen-antibody reaction. The first antibodies 211 are immobilized on the upper surface of the optical waveguide 23, for example, by hydrophobic interactions or chemical bonds that occur between the first antibodies 211 and the upper surface of the optical waveguide 23.

The reaction vessel 201 is, for example, empty beforehand. When measuring a test substance, a mixture 202 of a sample solution and a reagent is injected into the reaction vessel 201 from the outside, for example, through the hole 21a. The sample solution contains the test substance including an antigen 212. The reagent contains reagent components 213. The reagent components 213 include, for example, a second antibody 214 that specifically reacts with the antigen 212 through an antigen-antibody reaction, and magnetic particles 215 to which the second antibody 214 is bound. The magnetic particles 215 are at least partially formed from a magnetic material such as magnetite. The magnetic particles 215 are, for example, particles formed from a magnetic material, the surfaces of which are coated with a polymer material. Note that the magnetic particles 215 may also be configured to be particles made of a polymer material, the surfaces of which are coated with a magnetic material. The magnetic particles 215 may also be replaced with any material that is dispersible in the mixture 202.

By injecting the mixed liquid 202, the reaction vessel 201 contains the first antibody 211 immobilized on the upper surface of the optical waveguide 23, as well as the antigen 212 contained in the test substance in the sample solution and the reagent component 213 contained in the reagent. When the mixed liquid 202 is injected into the reaction vessel 201, the air inside the reaction vessel 201 is expelled to the outside through the hole 21b.

The reagent component 213 moves dispersibly within the mixed liquid 202 filled in the reaction vessel 201. The magnetic particles 215 are selected so that the gravity acting on the magnetic particles 215 is greater than the buoyancy in the mixed liquid 202, which acts in the opposite direction to gravity. The magnetic particles 215 to which the second antibody 214 is bound are immobilized near the upper surface of the optical waveguide 23 as the second antibody 214 binds to the first antibody 211 via the antigen 212. The second antibody 214 may be the same as or different from the first antibody 211.

In the biological reaction device 2, a first antibody 211 immobilized on the upper surface of the optical waveguide 23 reacts with an antigen 212 contained in the test substance, causing magnetic particles 215 to which a second antibody 214 is bound to be immobilized near the upper surface of the optical waveguide 23. Light guided through the optical waveguide 23 is scattered and absorbed by the magnetic particles 215 immobilized near the upper surface of the optical waveguide 23. As a result, the light guided through the optical waveguide 23 is attenuated before being emitted from the optical waveguide 23. In other words, the incident light L1 is attenuated according to the amount of antigen 212 that binds the first antibody 211 and the second antibody 214 immobilized on the magnetic particles 215. In other words, the incident light L1 is attenuated according to the amount of antigen 212 contained in the reaction vessel 201.

Hereinafter, the region of the reaction vessel 201 that is a distance L away from the surface of the optical waveguide 23 in the vertical direction upward, i.e., the region extending to the vicinity of the surface of the optical waveguide 23, is defined as the sensing area 205.

When light propagates through the optical waveguide 23, near-field light (hereinafter referred to as evanescent light) is generated on the upper surface of the optical waveguide 23. The sensing area 205 is a region where evanescent light can be generated. In the sensing area 205, a first antibody 211 immobilized on the upper surface of the optical waveguide 23 binds to a second antibody 214 immobilized on magnetic particles 215 contained in a reagent component 213 via an antigen 212 contained in the analyte in the sample solution. This causes the magnetic particles 215 to which the second antibody 214 is bound to be held near the upper surface of the optical waveguide 23.

Next, we will explain the effect on light propagating through the optical waveguide 23 of antigen-antibody reactions and the like that occur in the reaction vessel 201. Note that the first antibody 211, second antibody 214, and antigen 212 are very small compared to the magnetic particles 215. In Figure 2, to schematically illustrate the binding reaction, the first antibody 211, antigen 212, second antibody 214, and magnetic particles 215 are shown as being of similar sizes.

When the magnetic particles 215 enter the sensing area 205, the second antibodies 214 immobilized on the magnetic particles 215 bind to the first antibodies 211 immobilized on the upper surface of the optical waveguide 23 via the antigens 212. As a result, the magnetic particles 215 to which the second antibodies 214 are bound remain in the sensing area 205. When evanescent light is generated on the upper surface of the optical waveguide 23 while the magnetic particles 215 remain in the sensing area 205, the magnetic particles 215 remaining in the sensing area 205 scatter and absorb this evanescent light, thereby attenuating the evanescent light. This scattering and absorption of the evanescent light in the sensing area 205 affects the light propagating within the optical waveguide 23. In other words, as the evanescent light is attenuated in the sensing area 205, the light optically guided within the optical waveguide 23 is also attenuated. Therefore, when evanescent light is strongly scattered and absorbed in the sensing area 205, the intensity of the light propagating through the optical waveguide 23 decreases. In other words, the greater the amount of magnetic particles 215 remaining in the sensing area 205, the lower the intensity of the light output from the optical waveguide 23.

However, the magnetic particles 215 remaining within the sensing area 205 are not limited to those formed by binding the first antibody 211 immobilized on the upper surface of the optical waveguide 23 via the antigen 212 to be measured to the second antibody 214 immobilized on the magnetic particle 215. Therefore, in order to accurately measure the concentration of the antigen 212 contained in the test substance, it is necessary to move away from the sensing area 205 magnetic particles 215 bound to the second antibody 214 that is not involved in the measurement, i.e., not bound to the antigen 212. A specific method is to use the proximity effect of a magnetic field to move the magnetic particles 215 to which the second antibody 214 is not bound to the antigen 212.

As a result, the magnetic particles 215 that ultimately remain in the sensing area 205 are bound to the first antibody 211 immobilized on the upper surface of the optical waveguide 23 via the antigen 212, and the second antibody 214. Therefore, the intensity value of the light emitted from the biological reaction device 2 and the time series changes in intensity correspond to the amount and concentration of the magnetic particles 215 that remain in the sensing area 205.

The biological reaction device 2 may be configured to be capable of simultaneously measuring the same test substance in parallel across multiple channels for the same measurement item. In this case, the biological reaction device 2 may have, for example, an independent optical waveguide for each channel.

Next, we will explain the sample testing device 10A, which is the master sample testing device 10. Figure 3 is a block diagram showing an example of the configuration of the sample testing device 10A according to this embodiment.

First, the configuration of the input/output device 40 of the sample testing device 10A will be described. The input/output device 40 is mounted on the top surface of the sample testing device 10A and includes an output device 41 and an input device 42.

The output device 41 has a display 411 and a printer 412. For example, in FIG. 1, the front of the input/output device 40 of the sample testing device 10A is tilted so that the user can easily view the display 411.

The display 411 displays various types of information. For example, the display 411 displays various images generated by the processing circuitry 34 (described below) and a GUI (Graphical User Interface) for receiving various operations from the user. For example, the display 411 is a liquid crystal display, an OLED (Organic Light Emitting Diode) display, a CRT (Cathode Ray Tube) display, or the like. Under the control of the processing circuitry 34 (described below), the display 411 displays, for example, various operation screens, information indicating the light intensity of the emitted light L2 supplied from the photodetector 312 (described below), time-series data of the information indicating the light intensity, and information related to the test. Information related to the test includes, for example, the test results of the test. The test results are, for example, the amount (concentration, weight, number, etc.) or presence or absence of antigen 212. The display 411 is an example of a "display unit."

Under the control of the processing circuit 34 (described below), the printer 412 prints, for example, various operation screens displayed on the display 411, information indicating the light intensity of the emitted light L2 supplied from the photodetector 312 (described below), time-series data of the information indicating the light intensity, and test results for the test substance. The printer 412 is an example of a "printing unit."

The input device 42 may be realized by, for example, a trackball, switches, buttons, a mouse, a keyboard, a touchpad that performs input operations by touching the operation surface, or a touch panel display that integrates a display screen and a touchpad. The input device 42 outputs operation input signals corresponding to user operations to the processing circuit 34, described below. Note that in this embodiment, the input interface circuit is not limited to those equipped with physical operation components such as a mouse and keyboard. For example, an electrical signal processing circuit that receives electrical signals corresponding to input operations from an external input device provided separately from the device and outputs these electrical signals to the processing circuit 34, described below, is also included as an example of an input interface circuit. The input device 42 is an example of an "input unit."

Next, the configuration of the main body 30 of the sample testing device 10A will be described.

As shown in FIG. 3, the main body 30 has a detection unit 31. The detection unit 31 has a light source 311, a photodetector 312, and a reading device 313.

The light source 311 is, for example, a diode such as an LED (Light Emitting Diode) or a lamp such as a xenon lamp. The light source 311 is positioned so that light can be incident into the optical waveguide 23 toward the grating 23a shown in FIG. 2. The light source 311 emits incident light L1 into the optical waveguide 23 through the transparent substrate 22 of the biological reaction device 2.

The photodetector 312 outputs an electrical signal based on the reaction state within the reaction vessel 201 containing the mixed liquid 202. Specifically, the photodetector 312 detects the outgoing light L2 emitted from the optical waveguide 23 and generates an electrical signal indicating the intensity of the detected outgoing light L2, i.e., digital data related to the detected light intensity. The digital data related to the detected light intensity generated by the photodetector 312 is supplied to the processing circuit 34, which will be described later.

The detection unit 31 may be configured to be capable of simultaneously measuring the same test substance in parallel across multiple channels for the same measurement item. In this case, the detection unit 31 may have a light source and photodetector for each channel, or the light source and photodetector may be shared.

The detection unit 31 also has a detector that detects whether the cover 20 is opened or closed relative to the main body 30. When the detector detects that the cover 20 has been opened relative to the main body 30, it outputs information indicating that the cover 20 has been opened to the processing circuit 34. When the detector detects that the cover 20 has been closed relative to the main body 30, it outputs information indicating that the cover 20 has been closed to the processing circuit 34.

The reading device 313 reads the type of detection target from the identifier provided on the biological reaction device 2 and outputs read information indicating the type of biological reaction device 2 to the processing circuit 34. Specifically, an identifier identifying the type of biological reaction device 2 is provided on the back surface of the biological reaction device 2. For example, if the detection target is a test substance containing an antigen 212 such as virus A or virus B, the type of biological reaction device 2 may be a biological reaction device 2 for virus A testing or a biological reaction device 2 for virus B testing. For example, a QR code (registered trademark) 2a identifying the type of biological reaction device 2 is printed on the back surface of the biological reaction device 2. When the biological reaction device 2 is attached to the mounting base 4 of the main body 30, the reading device 313 reads the type of biological reaction device 2 from the QR code (registered trademark) 2a printed on the back surface of the biological reaction device 2 and outputs read information indicating the type of biological reaction device 2 to the processing circuit 34.

For example, the types of detection targets are color-coded, with green and blue assigned to biological reaction devices 2 for testing for virus A and virus B, respectively. Specifically, biological reaction devices 2 for testing for virus A and the reagent packages that react with the biological reaction devices 2 are color-coded green. Similarly, biological reaction devices 2 for testing for virus B and the reagent packages that react with the biological reaction devices 2 are color-coded blue.

In this embodiment, a QR code (registered trademark) 2a is used as an identifier to identify the type of biological reaction device 2, but this is not limited to this and, for example, a barcode or the like may also be used.

As shown in Figure 3, the main body 30 further includes a magnetic field generator 32, a memory circuit 33, and a processing circuit 34.

The magnetic field generator 32 generates energy that promotes the reaction in the reaction vessel 201 shown in FIG. 2, i.e., the binding between the second antibody 214 immobilized on the magnetic particles 215 and the first antibody 211 immobilized on the upper surface of the optical waveguide 23 via the antigen 212. Specifically, as shown in FIG. 3, the magnetic field generator 32 has an upper magnetic field generator 32a and a lower magnetic field generator 32b. The magnetic field generator 32 also has a drive circuit (not shown). The magnetic field generator 32 applies a magnetic field to the reaction vessel 201 under the control of the processing circuit 34.

The lower magnetic field generator 32b is composed of, for example, a permanent magnet and an electromagnet. The lower magnetic field generator 32b is provided below the biological reaction device 2. Specifically, the lower magnetic field generator 32b is provided below the mounting base 4 on which the biological reaction device 2 is mounted. For example, the timing to start and stop applying the lower magnetic field is predetermined. The lower magnetic field generator 32b generates a vertically downward magnetic field uniformly in the horizontal direction, which is the energy that promotes the reaction in the reaction vessel 201. The generated vertically downward magnetic field causes the magnetic particles 215 to which the second antibody 214 is bound to be subjected to a vertically downward force and to descend. At this time, the lower magnetic field generator 32b generates a magnetic field of a predetermined strength, thereby bringing the magnetic particles 215 to which the second antibody 214 is bound closer to the optical waveguide 23.

The upper magnetic field generator 32a is composed of, for example, a permanent magnet and an electromagnet. As shown in FIG. 2, the upper magnetic field generator 32a is disposed above the biological reaction device 2. For example, the timing for starting and stopping the application of the upper magnetic field is predetermined. For example, the timing for starting the application of the upper magnetic field is set to a predetermined time after the application of the lower magnetic field is stopped. The upper magnetic field generator 32a generates a uniform vertically upward magnetic field in the horizontal direction in the reaction vessel 201. The generated vertically upward magnetic field causes the magnetic particles 215 to which the second antibody 214 is bound to rise due to a vertically upward force. At this time, the upper magnetic field generator 32a generates a magnetic field of a predetermined strength, selectively moving the magnetic particles 215 to which the second antibody 214 is bound away from the sensing area 205. In other words, by adjusting the strength of the magnetic field generated by the upper magnetic field generator 32a, it is possible to retain in the sensing area 205 only magnetic particles 215 bound to second antibodies 214 that are bound via first antibodies 211 and antigens 212 and are fixed to the upper surface of the optical waveguide 23.

The memory circuitry 33 includes a processor-readable storage medium, such as a magnetic or optical storage medium or semiconductor memory. The memory circuitry 33 stores programs executed by the circuits of the sample testing apparatus 10A. Note that some or all of the programs and data stored in the storage medium of the memory circuitry 33 may be configured to be downloaded via an electronic network.

The memory circuitry 33 stores information indicating the light intensity of the emitted light L2 supplied from the photodetector 312, time-series data of the information indicating the light intensity, and test results for the test substance being measured.

The memory circuitry 33 stores a time schedule for measuring the target test substance. The time schedule includes, for example, the timing at which application of the lower magnetic field generated by the lower magnetic field generator 32b begins, the timing at which application of the lower magnetic field ends, the timing at which application of the upper magnetic field begins, and the timing at which measurement is performed. These timings are obtained in advance empirically and experimentally.

The processing circuitry 34 is a processor that controls, for example, each component circuit of the specimen testing apparatus 10A. The processing circuitry 34 functions as the central part of the specimen testing apparatus 10A. The processing circuitry 34 calls each operating program from the memory circuitry 33 and executes the called programs to realize a control function 341, a communication function 342, and a measurement function 343. The control function 341 is an example of a "control unit." The communication function 342 is an example of a "communication unit." The measurement function 343 is an example of an "examination unit."

The measurement function 343 uses the biological reaction device 2, light source 311, photodetector 312, and magnetic field generator 32 to perform an examination to detect the target substance contained in the sample.

Specifically, the measurement function 343 controls the light source 311 to generate light under predetermined conditions. In the measurement function 343, the processing circuit 34 causes the light source 311 to generate incident light L1 continuously or intermittently at least from the start to the end of measurement.

The measurement function 343 also controls the magnetic field generator 32 according to the time schedule stored in the memory circuitry 33, switching the state of energy application that promotes the reaction in the reaction vessel 201 of the biological reaction device 2. Specifically, as described above, the timing to start applying the lower magnetic field, the timing to stop applying the lower magnetic field, the timing to start applying the upper magnetic field, and the timing to stop applying the upper magnetic field are predetermined, and the timing to start applying the upper magnetic field is set to a predetermined time after the timing at which the application of the lower magnetic field is stopped. The measurement function 343 reads the time schedule from the memory circuitry 33, controls the magnetic field generator 32 based on the read time schedule, and causes the magnetic field generator 32 to generate a magnetic field.

The measurement function 343 also derives test results related to the amount (e.g., antigen concentration) or presence or absence of the test substance from the optical signal supplied from the optical detector 312. For example, the timing for deriving the test results is predetermined and set to a predetermined time after the application of the upper magnetic field begins. The measurement function 343 reads the time schedule from the memory circuitry 33 and derives the test results from the optical signal supplied from the optical detector 312 based on the read time schedule.

For example, when a predetermined time has elapsed since the start of application of the upper magnetic field, the measurement function 343 determines whether the sample solution is likely to be positive or negative, and derives the determination result as the test result. Specifically, the measurement function 343 makes the determination by comparing the intensity of the optical signal acquired when a predetermined time has elapsed since the start of application of the upper magnetic field with a threshold value stored in, for example, the memory circuitry 33. Here, if the intensity of the acquired optical signal is below the threshold, the measurement function 343 determines that the measurement result of the test substance is likely to be positive, and derives the determination result as the test result. On the other hand, if the intensity of the acquired optical signal is greater than the threshold, the measurement function 343 determines that the measurement result of the test substance is likely to be negative, and derives the determination result as the test result.

The control function 341 outputs the test results to the output device 41. For example, the control function 341 controls the display 411 or printer 412 as the output device 41 to present information about the test to the user. Specifically, the control function 341 presents the test results regarding the amount or presence or absence of the test substance to the user by displaying them on the display 411 or printing them out on a printer.

The control function 341 also controls the specimen testing device 10A, which is its own device, and the specimen testing devices 10B and 10C. The control of the control function 341 will be described later.

The communication function 342 communicates with the sample testing devices 10B and 10C.

Next, we will explain the specimen testing devices 10B and 10C, which are slave specimen testing devices 10. Figure 4 is a block diagram showing an example of the configuration of specimen testing devices 10B and 10C according to this embodiment.

As mentioned above, the sample testing devices 10B and 10C are not equipped with an input/output device 40 due to cost considerations.

The measurement function 343 performs testing to detect the target substance contained in the sample using the biological reaction device 2, light source 311, photodetector 312, and magnetic field generator 32. The communication function 342 communicates with the sample testing apparatus 10A. The control function 341 operates under control from the sample testing apparatus 10A. The control of the control function 341 will be described later.

The term "processor" used in the above description refers to circuits such as a CPU (Central Processing Unit), GPU (Graphics Processing Unit), Application Specific Integrated Circuit (ASIC), programmable logic device (e.g., Simple Programmable Logic Device (SPLD), Complex Programmable Logic Device (CPLD), and Field Programmable Gate Array (FPGA)). If the processor is a CPU, for example, the processor realizes its functions by reading and executing a program stored in the memory circuitry 60. On the other hand, if the processor is an ASIC, for example, the program is directly embedded in the processor circuitry instead of being stored in the memory circuitry 60. Note that each processor in this embodiment is not limited to being configured as a single circuit per processor; it may also be configured as a single processor by combining multiple independent circuits to realize its functions. Furthermore, the multiple components in Figures 3 and 4 may be integrated into a single processor to realize its functions.

Here, the specimen testing system includes multiple specimen testing devices 10, each consisting of a master specimen testing device 10 and a slave specimen testing device 10. Therefore, for example, a user can operate multiple specimen testing devices to perform various tests simultaneously by operating only one master specimen testing device 10, thereby improving testing efficiency. Furthermore, because the slave specimen testing device 10 is not provided with an input/output device 40 for cost reasons, a specimen testing system capable of performing multiple tests simultaneously can be constructed inexpensively. However, because the slave specimen testing device 10 is not provided with an input/output device 40, the above specimen testing system suffers from the following problems.

For example, because the slave specimen testing apparatus 10 does not have an input/output device 40, there is a problem in that it is not clear what test is planned. Specifically, when virus B is tested using specimen testing apparatus 10B, which is the slave specimen testing apparatus 10, the user may mistakenly use a specimen testing apparatus other than specimen testing apparatus 10B. For example, the user may attach a biological reaction device 2 for virus B testing to specimen testing apparatus 10C. For example, the user may attach a biological reaction device 2 for virus A testing to specimen testing apparatus 10B. Thus, in the specimen testing system of this embodiment, if the wrong type of biological reaction device 2 is attached to the specimen testing apparatus 10, the test may have to be repeated, which may reduce testing efficiency.

Furthermore, because the slave specimen testing apparatus 10 does not have an input/output device 40, there is a problem in that it is unclear what is being tested. Specifically, when specimen testing apparatus 10B, which is the slave specimen testing apparatus 10, is testing for virus B, the cover 20 of specimen testing apparatus 10B is closed during testing, so the blue color coded on the biological reaction device 2 for virus B testing cannot be seen. In this situation, the user can confirm what test item is currently being tested by visually checking the screen displayed on the display 411 of specimen testing apparatus 10A, which is the master specimen testing apparatus 10. However, if the user cannot approach specimen testing apparatus 10A, which is displaying the screen, for example because the user is performing another task, they will not be able to see at a glance what test item is currently being tested. If the user approaches specimen testing apparatus 10A to check, they will have to interrupt their current task, which may reduce testing efficiency.

In order to improve testing efficiency, the sample testing system of this embodiment is provided with an indicator 35 on the main body 30 of each sample testing device 10A-10C in Figures 1, 3, and 4. The indicator 35 has a light-emitting element that can emit different colors. Examples of colors that the indicator 35 can emit include green and blue. The light-emitting element of the indicator 35 is formed to be easily visible to the user. For example, the light-emitting element of the indicator 35 is formed in a convex shape so that it protrudes from the front surface of the main body 30.

The specimen testing system of this embodiment performs the following processes to improve testing efficiency. The specimen testing device 10 of this embodiment is equipped with a measurement function 343, an input/output device 40, a communication function 342, and a control function 341 in the master specimen testing device 10. The measurement function 343 detects the target substance contained in the specimen. The input/output device 40 has a display 411 that displays information related to the test, and an input device 42 that accepts input of information related to the test. The communication function 342 communicates with the slave specimen testing device 10. Here, the slave specimen testing device 10 has a measurement function 343. The control function 341 causes the communication function 342 to transmit control information used to control the slave specimen testing device 10. For example, the master sample testing device 10 and the slave sample testing device 10 are further equipped with an indicator 35, and the control function 341 of the master sample testing device 10 controls the indicator 35 of the sample testing device 10 selected as the device to perform the test to emit light in a color corresponding to the type of detection target of the test by transmitting control information from the communication function 342. The control function 341 also processes the detection results received from the slave sample testing device 10.

Figures 5 to 7 are flowcharts showing the processing steps performed by the sample testing system 1 in this embodiment. Figures 8A to 8G are diagrams for explaining the processing performed by the sample testing system 1 in this embodiment.

In step S100 of FIG. 5, the control function 341 of the specimen testing device 10A, which is the master specimen testing device 10, receives a test order from, for example, an HIS (Hospital Information System) server, displays a list of the ordered tests to be performed based on the test order, and then receives a selection of test items to be detected. For example, as shown in FIG. 8A, the control function 341 displays a screen for receiving the selection of test items on the display 411, and receives the selection of test items to be performed via the input device 42.

Specifically, the control function 341 recognizes the operating status of the sample testing apparatuses 10A, 10B, and 10C, and causes the display 411 to display an area 110 that accepts the selection of a test item, an area 120 that displays the operating status of the sample testing apparatus 10A, an area 130 that displays the operating status of the sample testing apparatus 10B, and an area 130 that displays the operating status of the sample testing apparatus 10C, all in an overlapping manner. For example, the areas 110, 120, 130, and 140 each include tabs that are displayed in different positions, and the tabs for the areas 110, 120, 130, and 140 are labeled "Item," "1," "2," and "3" to identify the areas 110, 120, 130, and 140, respectively.

First, the control function 341 displays the entire area 110 and only the tabs for areas 120, 130, and 140 on the display 411. In this case, area 110 displays test item columns 111, 112, and 113, which accept the selection of test items. For example, test item columns 111, 112, and 113 are displayed on a row-by-row basis, and a test item can be selected by selecting a displayed row.

The test item column 111 displays the test item "Virus A," the patient ID "111111," the name "YYYY," and the usage status "3" of the patient who is the specimen. Here, the usage status "3" in the test item column 111 means that a test for "Virus A" is being performed by the specimen testing device 10C on the patient with ID "111111." In this case, the specimen testing device 10C is the specimen testing device currently performing the test, and the test item column 111 is not selectable by the user.

The test item column 112 displays the test item "Virus A," the patient ID "123456" of the specimen, the patient's name "XXXX," and the usage status "Waiting." Here, the usage status "Waiting" in the test item column 112 means that the patient with ID "123456" and name "XXXX" has not been tested for "Virus A." The test item column 113 displays the test item "Virus B," the patient ID "123456," the patient's name "XXXX," and the usage status "Waiting." Here, the usage status "Waiting" in the test item column 113 means that the patient with ID "123456" and name "XXXX" has not been tested for "Virus B." In this case, specimen testing devices 10A and 10B are specimen testing devices that are not currently conducting tests, and the test item columns 112 and 113 are selectable by the user.

Here, when the user selects test item columns 112 and 113, control function 341 accepts the selection of test items "Virus A" and "Virus B" as the detection target. For example, the patient displayed in test item columns 112 and 113 is a patient with ID "123456" and name "XXXX", so when the user selects test item column 112 or test item column 113, control function 341 accepts the selection of test items "Virus A" and "Virus B" as the detection target.

In step S101 of FIG. 5, the control function 341 of the specimen testing device 10A assigns the selected test items to each specimen testing device as detection targets.

Specifically, the control function 341 selects a specimen testing device that can perform testing from among the specimen testing devices 10A, 10B, and 10C. For example, the control function 341 selects specimen testing devices 10A and 10B to which an instruction to illuminate the indicator 35 (described below) has not been sent. The control function 341 then assigns the test items "Virus A" and "Virus B" selected in step S100 to the specimen testing devices 10A and 10B, respectively.

Alternatively, the control function 341 displays a list of specimen testing devices that can be used for testing from among the specimen testing devices 10A, 10B, and 10C, and then accepts the selection of a specimen testing device that can be used for testing via the input device 42. For example, the control function 341 accepts the selection of specimen testing devices 10A and 10B that can be used for testing by operating the input device 42. Then, the control function 341 assigns the test items "Virus A" and "Virus B" selected in step S100 to the specimen testing devices 10A and 10B, respectively.

In step S102 of Figure 5, the specimen testing apparatus 10A performs a test for the test item "virus A," and the specimen testing apparatus 10B performs a test for the test item "virus B."

First, we will explain the test for test item "Virus A" using the specimen testing device 10A.

In step S110 of FIG. 6, the control function 341 of the specimen testing apparatus 10A lights up the indicator 35 of the specimen testing apparatus 10A in green, which is the color-coded color for the test item "Virus A."

Specifically, the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10A to light up green before performing a test for the test item "Virus A." For example, as shown in FIG. 8B, the control function 341 of the specimen testing apparatus 10A lights up the indicator 35 of the specimen testing apparatus 10A in green.

Note that the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10A to light up in a color representing the test item "Virus A," but this is not limited to this. For example, if the indicator 35 has a light-emitting unit capable of displaying text, the control function 341 of the specimen testing apparatus 10A may control the indicator 35 of the specimen testing apparatus 10A to display the test item "Virus A" as text.

In step S111 of FIG. 6, the control function 341 of the sample testing apparatus 10A displays guide information for opening the cover 20 on the display 411 as guide information for the test performed by the sample testing apparatus 10A.

Specifically, as shown in FIG. 8C , the tab for area 120 displayed on the display 411 of the specimen testing apparatus 10A is displayed in green. Assume that the user selects the tab for area 120, which is displayed in green, the same color as the color lit on the indicator 35 of the specimen testing apparatus 10A. In this case, the control function 341 displays the entire area 120 and only the tabs for areas 110, 130, and 140 on the display 411. In this case, fields 121, 122, 123, and 124 are displayed in area 120. Field 121 displays the test item "Virus A." Field 122 displays the ID "123456" and name "XXXX" of the patient who is the specimen. Field 123 displays guide information for opening the cover 20 of the specimen testing apparatus 10A, such as the message "Please open the cover of the device whose lamp is lit." Field 124 displays the guide information for field 123 as an illustration.

In step S112 of FIG. 6, when the detection unit 31 of the sample testing device 10A detects from the main body 30 that the cover 20 has been opened, it outputs information indicating that the cover 20 has been opened.

In step S113 of FIG. 6, the control function 341 of the specimen testing apparatus 10A, in response to information indicating that the cover 20 has been opened, displays on the display 411 guide information for attaching the biological reaction device 2 as guide information for the test performed by the specimen testing apparatus 10A.

Specifically, as shown in Figure 8D, in area 120 displayed on the display 411 of the sample testing apparatus 10A, a message such as "Please install the test cartridge" is displayed in field 123 as guide information for attaching the biological reaction device 2 to the sample testing apparatus 10A. Field 124 displays the guide information in field 123 as an illustration.

In step S114 of FIG. 6, the reading device 313 of the sample testing apparatus 10A confirms the type of biological reaction device 2 attached to the sample testing apparatus 10A.

Specifically, when a biological reaction device 2 is attached to the specimen testing apparatus 10A, the reading device 313 reads the type of biological reaction device 2 from the QR code (registered trademark) 2a printed on the back of the biological reaction device 2 and outputs read information indicating the type of the biological reaction device 2. At this time, the control function 341 of the specimen testing apparatus 10A acquires the read information output from the reading device 313.

In step S115 of FIG. 6, the control function 341 of the specimen testing apparatus 10A compares the test item "Virus A" assigned to the specimen testing apparatus 10A with the type of biological reaction device 2 indicated by the acquired reading information, and displays the comparison result on the display 411 indicating whether the type of biological reaction device 2 is a device used for the test item "Virus A."

For example, suppose the type of biological reaction device 2 indicated by the read information is not the biological reaction device 2 for testing the test item "Virus A" assigned to the specimen testing apparatus 10A. In other words, if the biological reaction device 2 for testing for Virus A is not correctly attached to the specimen testing apparatus 10A (step S115 in Figure 6; No), the control function 341 of the specimen testing apparatus 10A notifies the user, for example, via a pop-up screen, that the type of biological reaction device 2 attached to the specimen testing apparatus 10A is incorrect. Then, step S113 is processed again.

For example, assume that the type of biological reaction device 2 indicated by the read information is a biological reaction device 2 for testing the test item "Virus A" assigned to the specimen testing apparatus 10A. In other words, if the biological reaction device 2 for testing for Virus A is correctly attached to the specimen testing apparatus 10A (Step S115 in Figure 6; Yes), processing of Step S116 is performed.

In step S116 of FIG. 6, the control function 341 of the specimen testing apparatus 10A displays on the display 411 guide information for the test performed by the specimen testing apparatus 10A, which guides the sending of liquid to the biological reaction device 2.

Specifically, as shown in Figure 8E, in area 120 displayed on the display 411 of the specimen testing apparatus 10A, a message such as "Please send liquid to the test cartridge" is displayed in field 123 as guide information urging the user to inject the mixture 202 of the sample solution and reagent into the reaction vessel 201 through the hole 21a of the biological reaction device 2. The guide information in field 123 is displayed as an illustration in field 124.

In step S117 of FIG. 6, the control function 341 of the specimen testing apparatus 10A displays, on the display 411, guide information encouraging the sending of liquid to the biological reaction device 2. After a predetermined time has elapsed, the control function 341 displays, on the display 411, guide information for closing the cover 20 as guide information for the test performed by the specimen testing apparatus 10A.

Specifically, as shown in FIG. 8F, in area 120 displayed on the display 411 of the sample testing apparatus 10A, a message such as "Please close the cover. Testing will begin" is displayed in field 123 as guide information for closing the cover 20. An illustration of the guide information in field 123 is displayed in field 124.

In step S118 of FIG. 6, when the detection unit 31 of the sample testing device 10A detects that the cover 20 is closed on the main body 30, it outputs information indicating that the cover 20 is closed.

In step S119 of FIG. 6, the measurement function 343 of the specimen testing apparatus 10A starts the test performed by the specimen testing apparatus 10A in response to the information indicating that the cover 20 is closed. At the same time, the control function 341 of the specimen testing apparatus 10A causes the indicator 35 of the specimen testing apparatus 10A to flash in green, which is the color-coded color for the test item "Virus A."

Specifically, the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10A to flash green while the test for test item "Virus A" is being performed. In this way, the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10A to emit light in different light forms before and during the test.

In step S119 of Figure 6, the control function 341 of the specimen testing device 10A monitors whether the test by the measurement function 343 has finished.

If the test of the measurement function 343 has not been completed (step S119 in Figure 6; No), the process of step S119 is performed again.

On the other hand, if the test by the measurement function 343 has finished (step S119 in Figure 6; Yes), the measurement function 343 of the specimen testing device 10A stores the test results for the test item "Virus A" in the memory circuitry 33, and the processing of step S120 is performed.

In step S120 of FIG. 6, the control function 341 of the sample testing device 10A turns off the indicator 35 of the sample testing device 10A.

In step S121 of FIG. 6, the control function 341 of the specimen testing apparatus 10A causes the output device 41 to output the test results for the test item "Virus A" performed by the measurement function 343. For example, the control function 341 controls the display 411 or printer 412 as the output device 41 to present the test results to the user. Specifically, the control function 341 presents the test results to the user by displaying them on the display 411 or printing them on a printer.

Next, we will explain the test for test item "Virus B" by specimen testing apparatus 10B. The control function 341 of specimen testing apparatus 10A causes the communication function 342 to transmit control information used to control specimen testing apparatus 10B, which is the slave specimen testing apparatus, and processes the detection results received from specimen testing apparatus 10B, as follows:

In step S130 of FIG. 7, the control function 341 of the specimen testing device 10A instructs the indicator 35 of the specimen testing device 10B to light up in blue, which is the color-coded color for the test item "Virus B."

Specifically, the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10B to light up in blue before conducting a test for the test item "virus B." In this case, the control function 341 of the specimen testing apparatus 10A sends a control signal, a lighting instruction to light up the indicator 35 in blue corresponding to the test item "virus B," to the specimen testing apparatus 10B via the communication function 342. Here, the control signal or lighting instruction is an example of "control information."

Note that the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10B to light up in a color representing the test item "Virus B," but this is not limited to this. For example, if the indicator 35 has a light-emitting unit capable of displaying text, the control function 341 of the specimen testing apparatus 10A may control the indicator 35 of the specimen testing apparatus 10B to display the test item "Virus B" as text.

In step S131 of FIG. 7, the control function 341 of the specimen testing apparatus 10B lights up the indicator 35 of the specimen testing apparatus 10B in a color representing the test item "Virus B" in response to the lighting instruction sent from the specimen testing apparatus 10A.

In step S132 of FIG. 7, the control function 341 of the sample testing apparatus 10A displays guide information for opening the cover 20 on the display 411 as guide information for the test performed by the sample testing apparatus 10B.

Specifically, as shown in FIG. 8G, the tab for area 130 displayed on the display 411 of the specimen testing apparatus 10A is displayed in blue. Assume that the user selects the tab for area 130, which is displayed in blue, the same color as the light on the indicator 35 of the specimen testing apparatus 10B. In this case, the control function 341 displays the entire area 130 and only the tabs for areas 110, 120, and 140 on the display 411. In this case, columns 131, 132, 133, and 134 are displayed in area 130. Column 131 displays the test item "Virus B." Column 132 displays the ID "123456" and name "XXXX" of the patient who is the specimen. Column 133 displays guide information for opening the cover 20 of the specimen testing apparatus 10B, such as the message "Please open the cover of the device whose lamp is lit." Column 134 displays the guide information for column 133 as an illustration.

Furthermore, in step S132, the communication function 342 of the sample testing device 10A sends a notification to the sample testing device 10B indicating that guide information for opening the cover 20 has been displayed on the display 411.

In step S133 of FIG. 7, when the detection unit 31 of the sample testing apparatus 10B detects that the cover 20 has been opened from the main body 30 of the sample testing apparatus 10B, it outputs information indicating that the cover 20 of the sample testing apparatus 10B has been opened. Here, the notification of step S132 is an example of "control information." For example, the communication function 342 of the sample testing apparatus 10B transmits information indicating that the cover 20 of the sample testing apparatus 10B has been opened to the sample testing apparatus 10A as a response to the notification of step S132.

In step S134 of FIG. 7, the control function 341 of the specimen testing apparatus 10A, in response to information indicating that the cover 20 of the specimen testing apparatus 10B has been opened, displays on the display 411 guide information for attaching the biological reaction device 2 to the specimen testing apparatus 10B as guide information for the test to be performed by the specimen testing apparatus 10B.

Specifically, in area 130 displayed on the display 411 of the sample testing apparatus 10A, a message such as "Please install the test cartridge" is displayed in field 133 as guide information for attaching the biological reaction device 2 to the sample testing apparatus 10B. Field 134 displays the guide information in field 133 as an illustration.

Furthermore, in step S134, the communication function 342 of the sample testing apparatus 10A sends a notification to the sample testing apparatus 10B indicating that guide information for attaching the biological reaction device 2 to the sample testing apparatus 10B has been displayed on the display 411.

In step S135 of Figure 7, the reading device 313 of the sample testing apparatus 10B confirms the type of biological reaction device 2 attached to the sample testing apparatus 10B.

Specifically, when a biological reaction device 2 is attached to the specimen testing apparatus 10B, the reading device 313 of the specimen testing apparatus 10B reads the type of the biological reaction device 2 from the QR code (registered trademark) 2a printed on the back of the biological reaction device 2 and outputs read information indicating the type of the biological reaction device 2. Here, the notification of step S134 is an example of "control information." For example, the communication function 342 of the specimen testing apparatus 10B transmits the read information output from the reading device 313 of the specimen testing apparatus 10B to the specimen testing apparatus 10A as a reply to the notification of step S134. At this time, the control function 341 of the specimen testing apparatus 10A acquires the read information output from the specimen testing apparatus 10B.

In step S136 of FIG. 7, the control function 341 of the specimen testing apparatus 10A compares the test item "Virus B" assigned to the specimen testing apparatus 10B with the type of biological reaction device 2 indicated by the acquired reading information, and displays on the display 411 the comparison result indicating whether the type of biological reaction device 2 is a device used for the test item "Virus B."

For example, suppose the type of biological reaction device 2 indicated by the read information is not the biological reaction device 2 for testing the test item "Virus B" assigned to the specimen testing apparatus 10B. In other words, if the biological reaction device 2 for testing for Virus B is not correctly attached to the specimen testing apparatus 10B (step S136 in Figure 7; No), the control function 341 of the specimen testing apparatus 10A notifies the user, for example, via a pop-up screen, that the type of biological reaction device 2 attached to the main body 30 of the specimen testing apparatus 10B is incorrect. Then, step S134 is processed again.

For example, assume that the type of biological reaction device 2 indicated by the read information is a biological reaction device 2 for testing the test item "Virus B" assigned to the specimen testing apparatus 10B. In other words, if the biological reaction device 2 for testing for Virus B is correctly attached to the specimen testing apparatus 10B (Step S136 in Figure 7; Yes), the process of Step S137 is performed.

In step S137 of FIG. 7, the control function 341 of the specimen testing apparatus 10A displays on the display 411 guide information for the test performed by the specimen testing apparatus 10B, which guides the sending of liquid to the biological reaction device 2 attached to the specimen testing apparatus 10B.

Specifically, in area 130 displayed on the display 411 of the specimen testing apparatus 10A, a message such as "Please send liquid to the test cartridge" is displayed in field 133 as guide information urging the user to inject the mixture 202 of the sample solution and reagent into the reaction vessel 201 through the hole 21a of the biological reaction device 2. Field 134 displays the guide information in field 133 as an illustration.

Furthermore, in step S137, the communication function 342 of the sample testing apparatus 10A sends a notification to the sample testing apparatus 10B indicating that guide information prompting the sending of liquid to the biological reaction device 2 attached to the sample testing apparatus 10B has been displayed on the display 411.

In step S138 of FIG. 7, the control function 341 of the specimen testing apparatus 10A displays, on the display 411, guide information encouraging the sending of liquid to the biological reaction device 2 attached to the specimen testing apparatus 10B, and then, when a predetermined time has elapsed, displays, on the display 411, guide information for closing the cover 20 of the specimen testing apparatus 10B as guide information for the test to be performed by the specimen testing apparatus 10B.

Specifically, in area 130 displayed on the display 411 of sample testing apparatus 10A, field 133 displays guide information for closing the cover 20 of sample testing apparatus 10B, such as the message "Please close the cover. Testing will begin." Field 134 displays the guide information in field 133 as an illustration.

Furthermore, in step S138, the communication function 342 of the sample testing device 10A sends a notification to the sample testing device 10B indicating that guide information for closing the cover 20 of the sample testing device 10B has been displayed on the display 411.

In step S139 of FIG. 7, when the detection unit 31 of the sample testing apparatus 10B detects that the cover 20 has been closed on the main body 30 of the sample testing apparatus 10B, it outputs information indicating that the cover 20 of the sample testing apparatus 10B has been closed. Here, the notifications of steps S137 and S138 are examples of "control information." For example, the communication function 342 of the sample testing apparatus 10B transmits information indicating that the cover 20 of the sample testing apparatus 10B has been opened to the sample testing apparatus 10A as a response to the notifications of steps S137 and S138.

In step S140 of FIG. 7, the control function 341 of the specimen testing apparatus 10A causes the indicator 35 of the specimen testing apparatus 10B to flash in blue, which is the color-coded color for the test item "Virus B."

Specifically, the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10B to flash blue while the test for test item "Virus B" is being performed. In this way, the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10B to emit light in different light forms before and during the test. In this case, the control function 341 of the specimen testing apparatus 10A sends a blinking instruction to the specimen testing apparatus 10B as a control signal via the communication function 342, to cause the indicator 35 to flash blue in accordance with the test item "Virus B." Here, the control signal or blinking instruction is an example of "control information."

In step S141 of FIG. 7, the control function 341 of the specimen testing apparatus 10B causes the indicator 35 of the specimen testing apparatus 10B to flash in a color representing the test item "Virus B" in response to the flashing instruction sent from the specimen testing apparatus 10A. At the same time, the measurement function 343 of the specimen testing apparatus 10B starts the test performed by the specimen testing apparatus 10B in response to the flashing instruction.

In step S142 of Figure 7, the control function 341 of the specimen testing device 10B monitors whether the test by the measurement function 343 has finished.

If the test of the measurement function 343 has not been completed (step S142 in Figure 7; No), the process of step S119 is performed again.

On the other hand, if the inspection of the measurement function 343 has been completed (step S142 in Figure 7; Yes), processing of step S143 is performed.

In step S143 of FIG. 7, the communication function 342 of the sample testing apparatus 10B transmits information to the sample testing apparatus 10A to report that the test performed by the sample testing apparatus 10B has been completed.

In step S144 of FIG. 7, the control function 341 of the sample testing device 10A turns off the indicator 35 of the sample testing device 10B in response to information reporting that the test performed by the sample testing device 10B has been completed.

In this case, the control function 341 of the sample testing apparatus 10A sends a control signal, a turn-off instruction to turn off the indicator 35, to the sample testing apparatus 10B via the communication function 342. Here, the control signal or the turn-off instruction is an example of "control information."

In step S145 of FIG. 7, the control function 341 of the sample testing apparatus 10B turns off the indicator 35 of the sample testing apparatus 10B in response to the turn-off instruction sent from the sample testing apparatus 10A.

In step S146 of FIG. 7, the communication function 342 of the specimen testing apparatus 10B transmits the test results for the test item "Virus B" performed by the specimen testing apparatus 10B to the specimen testing apparatus 10A in response to the light-off instruction. The measurement function 343 of the specimen testing apparatus 10A stores the test results for the test item "Virus B" in the memory circuitry 33.

In step S147 of FIG. 7, the control function 341 of the specimen testing apparatus 10A causes the output device 41 to output the test results for the test item "Virus B" performed by the specimen testing apparatus 10B. For example, the control function 341 controls the display 411 or printer 412 as the output device 41 to present the test results to the user. Specifically, the control function 341 presents the test results to the user by displaying them on the display 411 or printing them on a printer.

As explained above, in the specimen testing device 10 according to this embodiment, the measurement function 343 detects the target substance contained in the specimen. The input/output device 40 includes a display 411 that displays information related to the test, a printer 412 that prints the test results, and an input device 42 that accepts input of information related to the test. The communication function 342 communicates with the slave specimen testing device 10. Here, the slave specimen testing device 10 has the measurement function 343, but does not have an input/output device 40. In this case, the control function 341 causes the communication function 342 to transmit control information used to control the slave specimen testing device 10. For example, the master specimen testing device 10 and the slave specimen testing device 10 further include an indicator 35, and the control function 341 of the master specimen testing device 10 controls the indicator 35 of the specimen testing device 10 selected as the device to perform the test to emit light in a color corresponding to the type of target substance of the test by transmitting control information from the communication function 342. The control function 341 also processes detection results received from the slave specimen testing device 10. Note that, in this embodiment, a case has been described in which the slave specimen testing device 10 is not provided with an input/output device 40, but the slave specimen testing device 10 may be provided with an input/output device 40, or with an input/output device different from the input/output device 40 of the master specimen testing device 10. Also, although a case has been described in which the slave specimen testing device 10 is not provided with an input/output device 40, the slave specimen testing device 10 may be provided with a printer 412 that prints the test results.

Therefore, in the sample testing system of this embodiment, the master sample testing device 10 controls the slave sample testing devices 10, thereby improving testing efficiency.

For example, by having the master specimen testing apparatus 10 control the slave specimen testing apparatus 10, the user can understand what test is scheduled. Specifically, when a test for virus B is performed by specimen testing apparatus 10B, which is the slave specimen testing apparatus 10, the specimen testing apparatus 10B illuminates the indicator 35 in blue, corresponding to the test item "virus B." Therefore, the user can attach the biological reaction device 2 for virus B testing to the specimen testing apparatus 10B by visually checking the blue light emitted by the indicator 35 of the specimen testing apparatus 10B. This reduces the risk that the user will use a specimen testing apparatus other than the specimen testing apparatus 10B due to a misreading or other reason. In this way, the specimen testing system of this embodiment allows the user to correctly attach the biological reaction device 2 to the specimen testing apparatus 10, improving testing efficiency.

Furthermore, by having the master specimen testing apparatus 10 control the slave specimen testing apparatus 10, the user can understand what is being tested. Specifically, when specimen testing apparatus 10B, which is the slave specimen testing apparatus 10, is testing for virus B, the cover 20 of specimen testing apparatus 10B is closed during the test, but specimen testing apparatus 10B illuminates indicator 35 in blue, corresponding to the test item "virus B." Therefore, while performing another task, the user can check at a glance what test item is currently being tested by the illumination of indicator 35 of specimen testing apparatus 10B, without having to approach specimen testing apparatus 10A, which is displaying the screen. In this way, the specimen testing system of this embodiment allows the user to check what test item is currently being tested without interrupting the user's current task, thereby improving testing efficiency.

In addition, in the sample testing system of this embodiment, testing efficiency can be improved even with the sample testing device 10 alone.

For example, the master specimen testing apparatus 10 may be equipped with a measurement function 343 that uses a biological reaction device 2 to perform a test to detect a target substance contained in a specimen, an indicator 35 that can emit different colors, and a control function 341, allowing the user to understand what test is planned. Specifically, the control function 341 controls the indicator 35 to emit a color corresponding to the type of target substance, the same color as the color-coded biological reaction device 2 and the color-coded packaging of the reagent to be reacted with the biological reaction device 2. For example, if the specimen testing apparatus 10 is testing for virus A, the control function 341 causes the indicator 35 to emit a green color corresponding to the test item "virus A," the same color as the color-coded biological reaction device 2 for virus A testing and the color-coded packaging of the reagent to be reacted with the biological reaction device 2 for virus A testing. Therefore, the user can attach the biological reaction device 2 for virus A testing to the specimen testing apparatus 10 by visually checking the green light emitted by the indicator 35 of the specimen testing apparatus 10. In this way, the sample testing system of this embodiment allows the user to correctly attach the biological reaction device 2 to the sample testing apparatus 10, improving testing efficiency.

(Other embodiments)
Although the embodiments have been described above, the present invention may be embodied in various different forms other than the above-described embodiments.

In the above-described embodiment, the sample testing apparatus 10A, which is the master sample testing apparatus 10, has been described as processing when it receives a test order from, for example, an HIS server, but the embodiment is not limited to this. Below, processing performed without receiving a test order will be described. In processing performed without receiving a test order, for example, a biological reaction device 2 is attached to a sample testing apparatus 10 selected by a user from among multiple sample testing apparatuses 10 that is capable of testing. In this case, the sample testing apparatus 10A, which is the master sample testing apparatus 10, accepts testing by the selected sample testing apparatus 10.

Figures 9 and 10 are flowcharts showing the processing steps performed by the sample testing system 1 in a modified example of this embodiment.

Here, we will use Figure 9 to explain what happens when a user selects specimen testing apparatus 10A as the specimen testing apparatus 10 that can be tested and attaches a biological reaction device 2 for virus A testing to specimen testing apparatus 10A.

The processing procedure in Figure 9 differs from that in Figure 6; for example, steps S111, S112, S114, S200, S110, and S116 to S122 are executed. Here, in the processing in Figure 9, step S200 is executed instead of step S115 in Figure 6.

Specifically, as shown in FIG. 9 , steps S111, S112, and S114 are executed first. For example, in step S114, when the biological reaction device 2 is attached to the specimen testing apparatus 10A, the reading device 313 reads the type of the biological reaction device 2 from the QR code (registered trademark) 2a printed on the back of the biological reaction device 2, and outputs read information indicating the type of the biological reaction device 2. At this time, the control function 341 of the specimen testing apparatus 10A acquires the read information output from the reading device 313. Then, the processing of step S200 is performed.

In step S200 of FIG. 9, the control function 341 accepts the test to be detected based on the type of biological reaction device 2 represented by the acquired read information. For example, the type of biological reaction device 2 represented by the read information is a biological reaction device 2 for testing for virus A. In this case, the control function 341 accepts the test for the test item "Virus A" as the detection target based on the type of biological reaction device 2 represented by the read information. Then, processing of step S110 is performed.

For example, in step S110, the control function 341 controls the indicator 35 of the specimen testing device 10A to light up green before conducting a test for the test item "Virus A." Steps S116 to S122 are then executed.

Next, we will use Figure 10 to explain what happens when a user selects specimen testing apparatus 10B as the specimen testing apparatus 10 that can be tested and attaches a biological reaction device 2 for virus B testing to specimen testing apparatus 10B.

The processing procedure in Figure 10 differs from that in Figure 7; for example, steps S132 to S135, S210, S130, S131, and S137 to S147 are executed. Here, in the processing in Figure 10, step S210 is executed instead of step S136 in Figure 7.

Specifically, as shown in FIG. 10, steps S132 to S135 are executed first. For example, in step S135, when a biological reaction device 2 is attached to the sample testing apparatus 10B, the reading device 313 of the sample testing apparatus 10B reads the type of biological reaction device 2 from the QR code (registered trademark) 2a printed on the back of the biological reaction device 2 and outputs read information indicating the type of the biological reaction device 2. At this time, the communication function 342 of the sample testing apparatus 10B transmits the read information output from the reading device 313 of the sample testing apparatus 10B to the sample testing apparatus 10A as a reply to the notification of step S134. At this time, the control function 341 of the sample testing apparatus 10A acquires the read information output from the sample testing apparatus 10B. Then, step S210 is performed.

In step S210 of FIG. 10, the control function 341 accepts the test to be detected based on the type of biological reaction device 2 represented by the acquired read information. For example, the type of biological reaction device 2 represented by the read information is a biological reaction device 2 for virus B testing. In this case, the control function 341 accepts the test for the test item "Virus B" as the detection target based on the type of biological reaction device 2 represented by the read information. Then, steps S130 and S131 are processed.

For example, in step S130, the control function 341 of the specimen testing apparatus 10A controls the indicator 35 of the specimen testing apparatus 10B to light up in blue before performing a test for the test item "virus B." In this case, the control function 341 of the specimen testing apparatus 10A sends a control signal, via the communication function 342, to the specimen testing apparatus 10B, instructing it to light up the indicator 35 in blue, corresponding to the test item "virus B."

Next, in step S131, the control function 341 of the sample testing device 10B lights up the indicator 35 of the sample testing device 10B in a color representing the test item "Virus B" in response to the lighting instruction sent from the sample testing device 10A. Then, steps S137 to S147 are executed.

As explained above, in addition to the effects described above, the sample testing apparatus 10 according to this modified embodiment can accept testing by the selected sample testing apparatus 10 when a biological reaction device 2 is attached to the sample testing apparatus 10 selected by the user.

Here, we will explain the structure of the indicator 35.

Figure 11 is a side cross-sectional view showing a first structure, which is an example of the structure of the indicator 35 in the sample testing device 10 according to this embodiment. As shown in Figure 11, the indicator 35 includes a substrate 351, a multi-color LED (Light Emitting Diode) 352 provided on the substrate 351, and a case 353 that covers the multi-color LED 352.

The substrate 351 is provided on the front surface of the main body 30 of the sample testing device 10. The multicolor LED 352 is provided on the substrate 351 and is a light-emitting unit capable of emitting light of multiple colors. For example, the multicolor LED 352 emits any color by mixing the three primary colors of light: red (R), green (G), and blue (B). In order to emit any color, the multicolor LED 352 has three LEDs of red (R), green (G), and blue (B) arranged closely together.

When such a multicolor LED 352 is used to emit low-brightness colors such as brown or gray, the following situations can occur. First, for example, when external light is incident on the multicolor LED 352, the reflected light can make it difficult for the user to distinguish whether the LED is emitting light or not. In other words, when the LED is not emitting light, it may not appear dark to the user. Second, because the multicolor LED 352 has a structure in which three colored LEDs are arranged closely together, the light may not be mixed evenly.

In the example shown in Figure 11, the case 353 has a light mixing member 353a and a light blocking member 353b.

The light mixing member 353a is dome-shaped and mixes the multiple colors emitted by the multicolor LED 352. A white translucent resin, for example, is used as the light mixing member 353a. The light blocking member 353b is provided on the light mixing member 353a and blocks external light. A black light blocking paint, for example, is used as the light blocking member 353b. An opening 353c is formed at the top of the dome-shaped case 353, penetrating the light blocking member 353b and exposing the light mixing member 353a.

For example, the multiple colors emitted by the multicolor LED 352 are mixed by the light mixer 353a while being reflected by the dome-shaped inner wall of the light mixer 353a. In the structure of the light mixer 353a, the portion where the opening 353c is formed (the exposed portion) is thin, so the light whose colors have been uniformly mixed by the light mixer 353a is emitted from the opening 353c.

As a result, in the example shown in Figure 11, light whose colors have been uniformly mixed by the light mixing member 353a is emitted from the opening 353c. Also, in the example shown in Figure 11, the light blocking member 353b blocks external light from entering the multi-color LED 352, allowing the user to distinguish whether or not the LED is emitting light. In other words, when the LED is not emitting light, it appears dark to the user.

In the example shown in Figure 11, light whose colors have been uniformly mixed by the light mixer 353a is emitted from the opening 353c formed at the top of the dome-shaped case 353, so the range of emitted light is small. Therefore, in order to improve visibility, it is necessary to enlarge the exit port for emitting light whose colors have been uniformly mixed by the light mixer 353a. Therefore, in the example shown in Figure 12, the exit port is enlarged to improve visibility.

Figure 12 is a side cross-sectional view showing a second structure, which is an example of the structure of the indicator 35 in the sample testing device 10 according to this embodiment. As shown in Figure 12, the indicator 35 includes a substrate 351, a multi-color LED 352 provided on the substrate 351, and a case 354 that covers the multi-color LED 352. That is, in the example shown in Figure 12, the indicator 35 includes a case 354 instead of the case 353 in the example shown in Figure 11. The case 354 includes a light mixing member 354a, a light-blocking member 354b, and a light-attenuating member 354c.

The light-blocking member 354b is provided on the side of the case 354 and blocks external light. The light-blocking member 354b is, for example, a case made of black light-blocking paint. The light-mixing member 354a is provided facing the multi-color LED 352 on the light-blocking member 354b and mixes the multiple colors emitted by the multi-color LED 352. The light-mixing member 354a may be, for example, a white translucent film. The light-reducing member 354c covers the light-blocking member 354b and the light-mixing member 354a, and light whose colors have been uniformly mixed by the light-mixing member 354a is emitted from the light-reducing member 354c. The light-reducing member 354c may be, for example, a light-reducing film such as an ND (Neutral Density) filter. The light-blocking member 354b and the light-reducing member 354c are provided to improve the visibility of low-brightness colors.

For example, the multiple colors emitted by the multicolor LED 352 are mixed by being reflected between the light mixing member 354a and the substrate 351. Alternatively, the multiple colors emitted by the multicolor LED 352 are mixed by being reflected inside the light mixing member 354a. In the example shown in FIG. 12, the light mixing member 354a is not light-shielded, and a light-attenuating member 354c is provided on the light mixing member 354a, so that light whose colors have been uniformly mixed by the light mixing member 354a is emitted from the light-attenuating member 354c.

As a result, in the example shown in FIG. 12, light whose colors have been uniformly mixed by the light mixing member 354a is emitted from the dimming member 354c. Also, in the example shown in FIG. 12, the light blocking member 354b blocks external light entering the multi-color LED 352, allowing the user to distinguish whether or not the LED is emitting light. In other words, when the LED is not emitting light, it appears dark to the user. Furthermore, in the example shown in FIG. 12, the exit port for emitting light whose colors have been uniformly mixed by the light mixing member 354a can be made larger than in the example shown in FIG. 11, improving visibility. Furthermore, the provision of the dimming member 354c on the light mixing member 354a improves the visibility of low-brightness colors.

Here, we will explain how to dim the indicator 35.

Figure 13 is a diagram illustrating an example of dimming of the indicator 35 in the sample testing apparatus 10 according to this embodiment. For example, when a user requests dimming of the indicator 35 using the input device 42 in the sample testing apparatus 10A, which is the master sample testing apparatus 10, the control function 341 of the sample testing apparatus 10A accepts the request and displays a screen 360 such as that shown in Figure 13 on the display 411. In Figure 13, "LED1," "LED2," and "LED3" on the screen 360 are set by the user as the colors that will light up the indicator 35. For example, "LED1" and "LED2" are set by the user as colors that correspond to the test items "Virus A" and "Virus B," respectively.

The screen 360 shown in FIG. 13 includes adjustment units 361-363 for adjusting the brightness of the LEDs (light sources) of the three primary colors of light, red (R), green (G), and blue (B), in the multi-color LED 352 of the sample testing apparatus 10A, 10B, and 10C, and a setting button 364. Each of the adjustment units 361-363 includes a button that allows the user to adjust the color value using the input device 42; the higher the set color value, the brighter the light source of that color. In FIG. 13, the color value is displayed as "0" as the initial value. For example, if the user sets the red (R), green (G), and blue (B) values to their maximum values by operating the adjustment units 361-363 and then operates the setting button 364, the light emitted from the indicator 35 will be white.

Furthermore, if the user sets the red (R) value to the maximum value and the green (G) and blue (B) values to the minimum values by operating adjustment units 361 to 363 and then operates setting button 364, the light emitted from indicator 35 will be red. Similarly, if the user sets the green (G) value to the maximum value and the red (R) and blue (B) values to the minimum values by operating adjustment units 361 to 363 and then operates setting button 364, the light emitted from indicator 35 will be green. Similarly, if the user sets the blue (B) value to the maximum value and the red (R) and green (G) values to the minimum values by operating adjustment units 361 to 363 and then operates setting button 364, the light emitted from indicator 35 will be blue.

In this way, the user can set the red (R), green (G), and blue (B) values to any desired values by operating the adjustment units 361-363 and then operate the setting button 364, which causes the control function 341 of the sample testing device 10A to emit a low-brightness color, such as brown or gray, as the light emitted from the indicator 35.

The dimming of the indicator 35 is performed, for example, immediately before the specimen testing apparatus 10 is shipped, or when the specimen testing apparatus 10 is installed in a hospital or other facility. For example, to set blue as the color for the test item "Virus B," a user operates the adjustment units 361-363 to set the blue (B) value to the maximum value and the red (R) and green (G) values to the minimum values, and then operates the setting button 364. At this time, the control function 341 of the specimen testing apparatus 10A associates information representing the color set by the user on the screen 360 with information representing the test item and information representing a QR code (registered trademark) 2a that identifies the type of biological reaction device 2 used to test that test item, and stores this information in the memory circuitry 33 of the specimen testing apparatus 10A.

For example, in this embodiment, when a test order is received from the HIS server and the user selects the test items "Virus A" and "Virus B," the control function 341 of the sample testing device 10A lights up the indicators 35 of the sample testing devices 10A and 10B, which are capable of performing the test, in green and blue, respectively, as colors set by the user on the screen 360 to represent the test items "Virus A" and "Virus B."

In addition, in a modified example of this embodiment, when the reading device 313 reads the type of biological reaction device 2 from the QR code (registered trademark) 2a of the biological reaction device 2 attached to the specimen testing apparatus 10A, if a test for the test item "Virus A" is accepted based on the read type of biological reaction device 2, the control function 341 of the specimen testing apparatus 10A lights up the indicator 35 of the specimen testing apparatus 10A, which is a specimen testing apparatus capable of testing, in green, which the user has set on the screen 360 as the color-coded color for the test item "Virus A."

In this way, when the control function 341 of the specimen testing device 10A receives test items from a test order or QR code (registered trademark) 2a, it can light up the indicator 35 in a color set by the user on the screen 360 as a color-coded version of the received test item.

At least one of the embodiments described above can improve testing efficiency.
