Description

  The present invention relates to, for example, an information display device that displays various information, a liquid feeding device including the information display device, and a control method for the information display device.

Conventionally, in order to appropriately administer drugs and the like to a patient, an infusion device connected to an infusion device or the like has been proposed (for example, Patent Document 1).
Such an infusion device includes an infusion pump, a syringe pump, and the like disclosed in Patent Document 1. The infusion pump has a motor or the like inside, and by driving the motor or the like, the tube connected to the drip device is squeezed to adjust the amount of liquid medicine to be fed in the tube. The pump has a syringe main body for storing the chemical liquid therein and a syringe pusher for feeding the chemical liquid, and moves the syringe pusher with high precision by a driving force of a motor or the like, so that the chemical liquid in the syringe main body Is configured to accurately deliver liquid to the patient.
In addition, buttons and dials, which are various information input devices for nurses operating such an injection device to adjust the amount of liquid to be fed for each chemical solution, are provided on the injection device, and liquid injection to be adjusted A display or the like, which is a display unit for displaying the amount or the like, is also provided.

Therefore, a nurse or the like can adjust the injection amount of the chemical while visually checking the display.
Further, if the injection device continues to operate when an abnormality or the like occurs in the motor or the like of the liquid injection device, there is a risk of seriously affecting the patient or the like. In view of this, the injection device is configured such that when a signal from a motor or the like is input, the processing of the signal is prioritized.

JP 2007-185523 A

However, since the display control of the display, the motor control, and the like are both executed by the control unit such as the CPU of the injection device, they cannot be executed at the same time, and it is necessary to prioritize one of them.
Therefore, when a nurse or the like operates a button or dial that is an input device of the injection device and inputs data to be displayed on the display, etc., if motor control occurs, the motor control etc. There was a problem that priority was given to signal processing, and switching of the screen on the display became slow.
In particular, since the amount of information to be displayed on the display has increased in recent years, delays such as screen switching on the display have been problematic as it has increased the difficulty of operation for the operator.

  Therefore, an object of the present invention is to provide an information display device that is easy for an operator to operate, a liquid feeding device including the information display device, and a control method for the information display device.

In the present invention, the above-described object is to deliver a drug solution to a patient having a main control unit that generates various control signals, a sub-control unit that receives control signals from the main control unit, and a display unit. The control signal is one of various operation control signals, including a screen display signal related to screen configuration information displayed on the display unit and a signal not belonging to the screen display signal. Ri includes a control signal to the motor for driving the infusion pump or a syringe pump, the sub control unit, the screen display signal storage section for storing the screen display signal transmitted continuously in this order from the main control unit The screen display signal storage unit continuously sends the screen display signal to the sub-control unit without waiting for the sub-control unit to finish generating the screen configuration information. From the main control unit to transmit to the control unit The sub-control unit generates the screen configuration information based on the screen display signal from the screen display signal storage unit, The sub-control unit is configured to control to display on the display unit, and the sub-control unit does not belong to the screen display signal in parallel with the generation of the screen configuration information based on the screen display signal. This is achieved by a liquid delivery device comprising a processing unit that performs processing and execution on the motor.

According to the above configuration, the control signal received from the main control unit such as the CPU by the sub-control unit such as a field-programmable gate array (FPGA) includes the screen display signal. A screen display signal storage unit for storing signals is provided.
The sub-control unit that has received the screen display signal from the main control unit acquires the display data of the numerical value from the display data storage unit or the like based on the screen display signal, for example, the numerical display signal, and the numerical value is obtained. Screen configuration information in the display area or the like is generated and stored in an image configuration buffer or the like.
Thus, for example, the screen displayed on the display unit such as a display is divided and configured as screen information such as a plurality of areas, and each piece of information is transmitted from the main control unit to the sub-control unit. Etc.

In addition, since the main control unit cannot simultaneously transmit the screen display signals for a plurality of areas to the sub-control unit at the same time, the screen information signal such as the numerical display signal transmitted from the main control unit is, for example, for each area. Sent in order.
Therefore, the sub-control unit generates the screen configuration information for each area in order for each area.
Further, the sub-control unit repeats this operation for each area. For example, when the generation of screen configuration information for all areas for one screen is completed, one screen data is displayed on a display unit such as a display for the first time. The configuration is displayed.

By the way, conventionally, the main control unit cannot transmit a screen display signal for the next area while the sub control unit is generating individual screen configuration information. It waits for the end of the information generation operation, and then transmits a screen display signal for the next area.
In this case, the main control unit does not continuously transmit the screen display signal for each area to the sub-control unit, but performs intermittent transmission with a certain interval between the transmission of each screen display signal.

On the other hand, the main control unit also transmits a signal other than the display screen display signal that is a control signal to a part other than the information display device, for example, a motor control signal. Since the motor control signal or the like is more important information, it is given priority over the transmission of the screen display signal of the information display device.
Therefore, conventionally, when the main control unit transmits a screen display signal to the sub-control unit with a certain interval, if it is necessary to transmit the motor control signal or the like having priority, the motor control signal Such a situation has occurred that the transmission of etc. is performed between the screen display signals.
In this way, when the main control unit transmits each screen display signal, a signal that is not a screen display signal such as a motor control signal is transmitted to the sub control unit. The time for transmitting data becomes longer, and the data transmission completion time until the construction of one screen is completed becomes longer. Therefore, it takes a long time to display the screen on a display or the like, the switching of the screen is delayed, and it is difficult for the operator to operate.

  In particular, in recent years, as the resolution of displays has increased and the number of pixels handled has greatly increased, the types of screen data have increased, and it takes time to generate screen configuration information for all areas. Therefore, as described above, if the main control unit performs the transmission process of the motor control signal or the like between the screen display signals, the display of the screen such as the screen switching is further delayed, which is difficult for the operator. It became difficult to use.

Therefore, in the above configuration, the sub-control unit has a screen display signal storage unit, and this screen display signal storage unit stores a plurality of screen display signals from the main control unit.
As a result, the main control unit can continuously transmit the screen display signal of each area to the sub-control unit without waiting for the end of the generation operation of the screen configuration area data of the sub-control unit.
Therefore, the possibility that another signal such as a motor control signal is transmitted between the screen display signals of each area transmitted from the main control unit to the sub control unit is significantly reduced. The generation time is shortened, the screen can be quickly switched on a display or the like, and the liquid delivery device is easy to use for the operator.

Preferably, the numerical display signal from the dial is input to the main control unit without passing through the sub-control unit, and then transmitted to the screen display signal storage unit as the screen display signal. to.

In the present invention, the object is to provide a method for controlling a liquid delivery device, comprising: a main control unit that generates various control signals; a sub-control unit that receives control signals from the main control unit; and a display unit. The control signal of the main control unit is a screen display signal related to screen configuration information displayed on the display unit and a signal not belonging to the screen display signal, and is one of various operation control signals. Ah it is, includes a control signal to the motor for driving the infusion pump or a syringe pump, the sub control unit, the screen display of the said screen display signal transmitted from the main control unit in succession in order the sub-control unit Storing in the signal storage unit, and the screen display signal storage unit continuously receives the main control unit without waiting for the generation of the screen configuration information generation operation of the sub-control unit. Send the screen display signal to the sub-control unit In order, it has a structure for storing the screen display signal received from the main controller, the sub control unit, based on the screen display signals from the screen display signal storage unit, the screen configuration Generating sub information, the sub control unit displaying the screen configuration information on the display unit, and the sub control unit generating the screen configuration information based on the screen display signal. In parallel, the present invention is achieved by a control method for a liquid feeding device which performs processing / execution on the motor which does not belong to the screen display signal.
Preferably, the numerical display signal from the dial is input to the main control unit without passing through the sub-control unit, and then transmitted to the screen display signal storage unit as the screen display signal. Features.

As shown in FIG. 3, the display 3 is divided into a plurality of areas of different sizes, etc., and in each area, the syringe pump 1 indicates what data is displayed in which area. By doing so, a screen as shown in FIG. 2 is displayed.
That is, as will be described later, the syringe pump 1 generates screen configuration information (data to be displayed) for each area of the display 3, and after the screen configuration information for all areas is generated, the screen is displayed. 3 is displayed.

FIG. 4 is a schematic block diagram showing a functional configuration for operating the syringe pump 1 of FIG.
As shown in FIG. 4, the syringe pump 1 has, for example, a control unit (CPU or the like) 20 that is a main control unit, and the control unit 20 transmits a control instruction to each part of the syringe pump 1. It is configured to receive progress data from each part.
However, in the present embodiment, as shown in FIG. 4, for example, the control unit 30 includes a controlled unit 30 that is a sub-control unit, and the controlled unit 30 is configured such that the control unit 20 is a certain part of the syringe pump 1, for example, When the control data is transmitted to the display data 50, the display 3, the drip sensor 51, the bubble sensor 52, and the motor 53 or the progress status is received, the display data 50, the display 3, the drip sensor 51, and the motor 53 are arranged therebetween.

That is, when the control unit 20 transmits a control signal to the display 3 and the motor 53, the control signal is transmitted via the controlled unit 30.
Conversely, the control unit 20 receives the drip detection signal from the drip sensor 51 and also receives the bubble detection signal from the bubble sensor 52 via the controlled unit 30.

Here, for example, a CPU (Central Processing Unit) that is the control unit 20 employs a chip.
On the other hand, the controlled unit 30 is configured by, for example, a field-programmable gate array (FPGA), and the FPGA is a device that can realize a logical function desired by the user in a short period of time using the user's own computer. .
The syringe pump 1 has a computer. The computer has a RAM (Random Access Memory), a ROM (Read Only Memory), and the like in addition to the above-described CPU, and these are connected via a bus. ing.

The bubble sensor 52 is a sensor that detects bubbles in the tube 10 of FIG.
The motor 53 is a motor 53 for driving the syringe pump 1, and the buzzer 54 informs the operator of the occurrence of an abnormal situation when the syringe pump 1 has an abnormality such as a tube blockage. Equipment.

  FIG. 5 is a schematic block diagram showing main operations and the like of the controlled unit 30 of FIG. As illustrated in FIG. 5, the controlled unit 30 includes a controlled unit-side control unit 31 and controls various storage units, processing units (programs), and the like illustrated in FIG. 5. The contents of these various storage units will be described later.

FIG. 6 is a schematic flowchart showing the operation and the like of the syringe pump 1 according to the embodiment of the present invention.
The present embodiment will be described below using an example in which a nurse who is an operator inputs information to be displayed on the display 3 during the operation of the syringe pump 1.

First, when an operator of the syringe pump 1 such as a nurse operates the dial 5 of FIG. 1 and inputs, for example, numerical information “1”, etc., as shown in FIG. A signal is input to the control unit 20. Then, the control unit 20 should display the numerical information “1” and the like in the area of the numerical display 3a in the display 3 of FIGS. 2 and 3 with reference to the “display data 50” of FIG. The content screen display signal is transmitted to the controlled unit 30.
Further, for each area of the area of the display 3 in FIGS. 2 and 3, the control unit 20 receives a “screen display signal” having an instruction content indicating what data should be displayed in which area. Sent to.
However, since the control unit 20 cannot transmit these signals to the controlled unit 30 at the same time, the control unit 20 transmits the signals in order for each area.

Next, the process proceeds to step ST (hereinafter referred to as “ST”) 1 in FIG. In ST1, the “control unit signal distribution unit (program) 32” of FIG. 5 operates to determine whether or not the signal received from the control unit 20 is a “screen display signal”.
If it is determined in ST1 that the received signal is a “screen display signal”, the process proceeds to ST2.
In ST2, the received “screen display signal” is stored in, for example, “command buffer 33” which is a screen display signal storage unit. Here, for example, a “screen display signal” in the area of the numerical display 3a in FIG.

  On the other hand, if the received signal is not a “screen display signal” in ST1, the process proceeds to ST3, and signals other than this “screen display signal”, such as control signals for the motor 53 (an example of various operation control signals). Is stored in the “non-screen display signal storage unit 34” of FIG.

By the way, when stored in the “command buffer 33” in ST2, the process proceeds to ST4. In ST4, the “first processing unit (program) 35” of FIG. 5 operates, and the “display” (the signal of the area of the numerical display 3a) stored in the “command buffer 33” is “displayed”. Reference is made to “Data 50”.
In this “display data 50”, information to be displayed on the display 3, for example, the numerical display 3a information, the remaining battery charge 3b display information, the outlet display 3c information, the blockage display 3d information, etc. in FIG. Yes.
Therefore, the first processing unit (program) 35 acquires the data for “numerical value display 3a” of the display data 50 based on the screen display signal that is the signal of the area of the numerical value display 3a, as shown in FIG. “Screen configuration data” which is screen configuration information such as a large number “100.00” is generated.

  Then, the first processing unit (program) 35 stores the generated screen configuration data such as the number “100.00” in the “screen configuration buffer 37” of FIG.

Next, the process proceeds to ST5. In ST5, the “screen configuration buffer accumulation determination unit (program) 38” of FIG. 5 operates, and the screen configuration buffer 37 is referred to, and data for all areas for one screen is stored in the screen configuration buffer 37. It is determined whether or not.
That is, for example, it is determined whether or not “screen configuration data” in all areas such as the numerical display 3a, the remaining battery charge 3b, the outlet display 3c, and the blockage display 3d shown in FIG. .

This is because, in order to actually display the screen as shown in FIG. 2 on the display 3 as one screen, “screen configuration data” for all areas is necessary.
In the present embodiment, in ST5, even if the “screen configuration data” in the area of the numerical display 3a in FIG. 2 is stored, the “screen configuration data” in other areas such as the remaining battery level 3b is stored. When not completed, the operations of ST1, ST2 and ST4 are repeated.

  If it is determined in ST5 that “screen configuration data” has been stored for one screen, the process proceeds to ST6. In ST6, the “screen display unit (program) 39” of FIG. 5 operates, and the screen 3 is displayed on the display 3 based on the screen configuration data for all areas in the screen configuration buffer 37 as shown in FIG. Display a simple screen.

As described above, in the present embodiment, the screen display signals for each area of one screen displayed on the display 3 transmitted from the control unit 20 are sequentially transmitted to the controlled unit 30, but at this time, Each transmitted screen display signal is stored in the command buffer 33 of the controlled unit 30.
Therefore, as in the prior art, after the control unit 20 transmits, for example, a screen display signal for the numerical display 3a in FIG. 2, the controlled unit 30 performs screen configuration data based on the screen display signal. Until the operation for generating (numerical display 3a, etc.) is completed, the control unit 20 continuously transmits each screen area for one screen without waiting for transmission of a screen display signal such as the remaining battery level 3b. A screen display signal can be transmitted to the controlled unit 30.

For this reason, no interval is generated between the transmissions of the screen display signals. As a result, the control signal of the motor 53 that is important data for the syringe pump 1 is preferentially processed at this interval, and the control unit 20 The probability of being transmitted to the controlled unit 30 is extremely low.
As described above, in the present embodiment, the time for storing screen configuration data for all areas of one screen in the screen configuration buffer 37 is shortened, and quick screen display, screen switching, and the like are possible.
Therefore, the syringe pump 1 is easy to use for an operator such as a nurse.

By the way, after storing the control signal of the motor 53 in the “non-screen display signal storage unit 34” in ST3 of FIG. 6, the process proceeds to ST7.
In ST7, the “second processing unit (program) 40” of FIG. 5 of the controlled unit 30 operates, and for example, a motor control signal is a signal other than the non-screen display signal of the non-screen display signal storage unit 34. Execute.

Thus, in the present embodiment, the first processing unit (program) 35 of the controlled unit 30 executes screen display processing, and at the same time, the second processing unit (program) 40 performs processing other than screen display. Parallel processing is executed.
Therefore, since the processing such as the control signal of the motor 53, which is the priority processing, and the screen display processing can be performed simultaneously in parallel, it is possible to perform faster screen display, screen switching, and the like. Yes.
In particular, it is necessary to display a large amount of information on the display 3 of the syringe pump 1 in recent years, and it is extremely important to increase the speed of screen switching and the like accordingly.
In this regard, in this embodiment, such a large amount of information can be quickly displayed on the screen.

  By the way, the present invention is not limited to the above-described embodiment. In this embodiment, the “syringe pump 1” is used as the liquid delivery device. However, the liquid delivery device of the present invention is not limited to this and may be an “infusion pump” or the like.
