Description

  The present invention relates to an automatic analyzer for use in clinical examinations, such as an automatic analyzer for analyzing biological samples such as blood and urine, pre-processing for analysis, and post-processing, and a sample pre- and post-processing device.

  Automatic analyzers used in clinical tests are required to reduce running costs. Means for reducing running costs include eliminating waste of consumables and reducing labor costs, but improving the operating rate of the automatic analyzer is also one of the means.

  In order to improve the operating rate, it is necessary to shorten the maintenance time and to quickly perform a failure when a failure occurs.

  Maintenance of the automatic analyzer is usually (1) Consumables management such as reagent replacement and cleaning liquid exchange performed by the operator who operates the automatic analyzer, and (2) Advanced maintenance technology with specialized training by the auto analyzer manufacturer. There are management performed by the manager who has it, and (3) periodic maintenance performed by service personnel in the maintenance business.

  For example, reagent replacement performed by an operator is performed in the following steps. (1) The operator recognizes the presence or absence of the reagent to be replaced by referring to the reagent screen. (2) If there is a reagent that must be replaced, a reagent replacement list is output. (3) Go to the reagent store with the reagent list, and issue the corresponding reagent bottle with reference to the list. (4) While referring to the reagent replacement list, the operation is performed to set the delivered reagent bottle on the reagent disk of the corresponding automatic analyzer.

  The operation of setting the reagent bottle on the reagent disk is described in the instruction manual. If the operator is not familiar with the operation, the operation manual must be placed on the side of the reagent disk and referenced.

  In order to recognize the reagent bottle to be replaced, the operator must move to the automatic analyzer and refer to the reagent management screen. Wasted travel time and complicated operations for screen operation are required.

  In order to prepare reagent bottles to be replaced by an operator and set them in an automatic analyzer, the reagent list must be printed or a note must be taken on paper, which is inefficient and consumes paper.

  In order to perform this reagent replacement work quickly and accurately, Patent Document 1 discloses a technique in which identification information is provided in an automatic analyzer and reagent information is displayed on an information display terminal.

  There are various types of maintenance work for automatic analyzers. The plurality of operations include daily operations, weekly and monthly operations, and operations performed when a failure occurs. In particular, there are many cases where the operator is not familiar with the monthly work or the work to be performed when a failure occurs, and it is often necessary to refer to the instruction manual.

  When working while looking at the instruction manual, there may not be enough space to install the instruction manual, so after reading the instruction manual, move to the work area and work. Sometimes you have to repeat the process of reading. Maintenance work is not efficient and may take a lot of time.

  Service personnel in the maintenance industry must perform work in accordance with the maintenance work procedure manual. The maintenance work procedure manual, like the previous instruction manual, may not have enough space to install the maintenance work procedure manual, so read the maintenance work procedure manual and move to the work area. The work of reading the maintenance work procedure must be repeated. Maintenance work is not efficient and takes a lot of time.

  The automatic analyzer notifies the operator or manager of the occurrence of a failure with an alarm sound and a screen display. However, since operators and managers usually do not operate the automatic analyzer exclusively, they do not always work in a range where the alarm sound can be recognized or where the screen is visible. For this reason, the occurrence of an alarm may not be immediately recognized.

JP 2011-112524 A

  In Patent Document 1, an information display terminal and an automatic analyzer provide means for quickly and accurately performing reagent replacement by displaying reagent information using identification information. By utilizing this means, it is possible to consider displaying not only reagent information but also an instruction manual, for example, on the information display terminal.

  However, the instruction manual of the automatic analyzer is enormous and is divided into many volumes. To search for the location that the operator wants to refer to, display the table of contents and display the corresponding location, search by keyword. There are methods. All of these are complicated because a plurality of operation steps are required to refer to a target location.

  Further, when a procedure related to the reagent disk is performed, the location where the instruction manual should be referred to differs depending on the roles of the operator, the manager, and the like.

  For example, a case where the operation is performed on the reagent disk side is taken as an example. When the operator performs work on the reagent disk side, information on the remaining amount of the reagent, information on the reagent bottle to be replaced, and information on the reagent replacement location in the instruction manual are obtained.

  When the administrator of the automatic analyzer performs work on the side of the reagent disk, it asks whether it is time to replace the reagent probe, and information on the maintenance location of the reagent probe in the instruction manual.

  When the service staff performs work on the reagent disk side, information on the position of the reagent probe position adjustment procedure manual in the reagent probe position adjustment tool screen and the maintenance work procedure manual is obtained.

  The information required by the operator, manager, and service staff also varies depending on the status of the automatic analyzer.

  For example, when the automatic analyzer is in an operation state, the operator cannot perform reagent replacement. In preparation for reagent replacement, the operator wants to know the remaining amount of reagent in the reagent bottle or whether there is a reagent bottle to be replaced. Furthermore, in order to know when the automatic analyzer transitions to a standby state where reagent replacement can be performed, it is desired to know the analysis end time as a guide.

  When the automatic analyzer transitions to the standby state, the operator wants to know information on the analysis module, reagent disk, and reagent bottle with the reagent bottle to be replaced in order to set the prepared reagent bottle in the automatic analyzer.

  When a failure occurs, the operator wants to identify the location where the failure has occurred and know the procedure for recovering the automatic analyzer from the failure.

  That is, the information that the operator wants to know differs depending on the part of the automatic analyzer, preferably the authority of the operator, preferably the type of alarm. As a result, in order to know the information, the selection of the screen is repeated to access the target information. In order to perform the work, the corresponding instruction manual page must be searched and displayed.

  Maintenance time can be reduced by simplifying such complicated operations and facilitating access to information.

  The object of the present invention is to display the optimal information for the user on the screen from the user's authority, etc. using the portable terminal, thereby reducing the efficiency of the maintenance work of the automatic analyzer and reducing the recovery time when a failure occurs.

  Each of the functional units 120, 121, 122, 123, 124, 125, 126 has an identification unit 127, and the identification unit 127 includes a communication unit 129 between the information storage unit 128 and the portable terminal 130.

  The mobile terminal 130 includes a display unit 134 that displays information on a display device, an input unit 135 that uses a keyboard, a mouse, or a touch panel, an information storage unit 133, and a communication unit 131 that communicates with the communication unit 113 of the control unit 110. The communication unit 132 of the identification unit 127 included in the functional unit (input unit) 120 and the communication unit 129 is provided. Each of the functional units 120 to 126 includes a communication unit and can communicate with the communication unit 132 of the portable terminal, but the display is omitted in FIG.

  There may be a plurality of portable terminals such as the portable terminal 130a and the portable terminal 130b. In addition, since the structure of the portable terminals 130a and 130b is the same as the portable terminal 130, description of a structure is abbreviate | omitted. One portable terminal may be in charge of one or more automatic analyzers.

  The portable terminal 130 and the control unit 110 communicate via the wireless LAN 150.

  The portable terminal 130 and the identification unit 127 perform short-range wireless communication 160.

  The portable terminal 130 uses the communication unit 131 to make an information acquisition request to the communication unit 113 of the control unit 110 and stores the functional unit configuration information, operator ID information, and device status stored in the information storage unit 114. Information and alarm information are acquired and stored in the information storage means 133.

  The display information determination unit has a function of determining information to be displayed on the display unit 134 according to the identification information obtained from the identification unit, and displaying the determined information on the display unit 134.

  The sample analysis method of the automatic analyzer is well known and will not be described in detail. However, the sample to be analyzed input from the input unit passes through the sample transport unit, the ISE unit, and the sample sampling unit, and passes through the ISE. The sample is analyzed by analysis according to the above and analysis using a reagent. In general, it is known to analyze the component concentration of a predetermined item of a sample by mixing the reagent and the sample according to the test item, and measuring the absorbance of the mixed solution. The same inspection is possible with an automatic analyzer.

  An example of the configuration information of the functional unit of the automatic analyzer is shown in FIG. The functional unit configuration information includes, for example, identification information 201, a functional unit name 202, a functional unit serial number 203, and a maintenance date and time 204 when the functional unit is maintained, and is stored in the information storage unit 133.

  As shown in FIG. 2, identification information is allocated to each functional unit, and the mobile terminal can identify which functional unit is communicating by obtaining identification information via the communication means of each unit. . The correspondence relationship between the identification information and the information to be displayed is stored in the information storage unit 133 in advance, and the display information determination unit determines information to be displayed corresponding to the received identification information using this correspondence relationship. And displayed on the display means 134.

  When the serial number is included as shown in FIG. 2, the configuration information is shared between the information storage unit 114 included in the control unit and the information storage unit 133 of the portable terminal. . The serial number determined for each functional unit is managed by the control unit. When the functional unit is replaced, the serial information is also updated and stored in the information storage unit 114. When communication is performed by the communication means 113 and 131 between the portable terminal and the control unit, the serial number information is also transmitted.

Can be confirmed.

  Next, the operator ID information is shown in FIG. The operator ID information includes an operator ID 501, a password 502, an operator name 503, and operator authority 504.

  The operator authority 504 is used to limit the range in which the operator can refer to the display unit 111 of the control unit 110 of the automatic analyzer 100. It is also used to limit the screens and fields that can be input by the input means 112.

  That is, the operator authority is determined by the operator ID, and the operator authority is specified by specifying the operator ID. Such operator ID information is already stored in the information storage means 114 of the control unit, and this operator ID information is notified to the portable terminal. Since the operator ID of the mobile terminal is specified when the mobile terminal is used, display information such as a screen that can be input by the input means of the mobile terminal is determined by the operator ID information received by the mobile terminal and the operator ID. Means can be determined. Thus, since the information according to the operator ID can be obtained on the portable terminal side, the operability is greatly improved.

  It is also used to determine the display location of electronic data of the electronic instruction manual stored in the information storage means 133 of the mobile terminal 130.

  When the operator whose operator ID is “Operetor 1” places the portable terminal 130 on the identification means 128 installed on the upper part of the reagent disk unit 126, the communication means 132 and the communication means 160 communicate and are stored in the storage means 128. The identification information is taken out and the electronic instruction manual is stored in the information storage means 133.

  Triggered by the fact that the unit identification information is stored in the information storage unit 133, the display information determination unit 136 determines information to be displayed on the display unit 134. As described above, by combining the operator ID information and the identification information, it is possible to specify which part of which volume information is requested from among the multiple volumes that have the mobile terminal from the operator authority. Therefore, by combining the combination information of the operator ID and the identification information and the display page of the separate volume in advance and displaying them immediately on the mobile terminal, the terminal user can save time to search for a necessary part from the instruction manual. it can.

  Information displayed on the display means 134 is registered by the functional unit display information setting screen 300, and an example of the functional unit display information setting screen 300 is shown in FIG. The functional unit display information setting screen 300 has a functional unit identification information input area 301, a functional unit name display area 302, a screen input area 303 for inputting a screen to be displayed by default for each operator, administrator, and service person, that is, for each operator authority. , And display screen input areas 304, 305, and 306 for each alarm and each device status.

  The value DR0001 input to the default screen 303 indicates a module overview screen that provides an overview of the entire module.

  A001 input in the input area 304 of the operator display screen indicates a calibration alarm, and DM30025 indicates a calibration selection screen.

  A902 input to the input area 304 of the operator's display screen indicates a reagent-related alarm, and OM32301 is Volume 3 of the operation manual 400. It shows that a calibration setting page is displayed.

  When an alarm of A902 occurs when the operator ID is a service person, SM10185 is set. SM10185 indicates that the calibration error recovery page of page 185 of the first volume of the service manual is displayed.

  The value input on the functional unit display screen is registered in the display information setting table 600.

  Thus, on the setting screen, according to the authority of the operator, display information corresponding to the alarm, for example, the display page of the instruction manual is set in association with each other, and the alarm information is received from the control unit. In addition, by immediately displaying the corresponding display page on the mobile terminal, the operator who has the mobile terminal can obtain the requested information without feeling complicated to search the instruction manual one by one.

  An example of the display information management table 600 is shown in FIG. The display information management table 600 includes functional unit identification information 601, operator authority 602, display code 603, and screen number 604. In this way, the function unit identification information and the screen number to be displayed on the mobile terminal are associated in advance, or the combination of the function unit identification information and the operator authority and the screen number to be displayed on the mobile terminal. By associating with each other, the mobile terminal receives the identification information, or the identification information and the operator authority are received, so that the screen associated with the mobile terminal can be displayed immediately.

  In addition, as an application, by adding the operation status information column of the control unit to the table of FIG. 6, predetermined display information to be displayed is associated with the combination of operator ID information, operation status information, and identification information. When the mobile terminal receives these pieces of information, the associated screen can be immediately displayed on the mobile terminal.

  As another function, when the mobile terminal receives the identification information of the predetermined functional unit and receives the identification information of another functional unit while displaying the predetermined information, the display information determining means Re-decides information to be displayed on the display means according to the new identification information, and displays the re-determined information on the display means. By configuring in this way, maintenance or the like of another functional unit can be performed quickly.

  On the other hand, in order to prevent another information from being displayed on the display unit by inadvertently communicating with another functional unit, the portable terminal has a function of locking the screen of the display unit. By inputting the information for locking the screen through the input means in advance, even if new identification information is received, the already displayed screen can be continuously displayed without updating the screen. .

  Also, by setting the time for receiving the identification information to the mobile terminal in advance, display candidates for displaying which of the information corresponding to each of the plurality of identification information within the set time are displayed and displayed. Information corresponding to the identification information selected from the candidates by the input means of the portable terminal can be displayed on the display means. The set time can be changed as appropriate. In this way, even if a plurality of pieces of identification information are received by mistake, information corresponding to the identification information intended by the operator, manager, or service person who possesses the mobile terminal is determined as display information. The means can be displayed.
