The operation/display panel 1 has a display surface of a display board 4 which is a character and image display device composed of a liquid crystal (cathode ray tube, plasma display, fluorescent display board, electroluminescence panel). It is constructed by stacking transparent switch panels 5, and the display board 4 is connected via an image control device 6.
A transparent switch panel 5 is connected to the CPU 2 via a key interface 7, while a transparent switch panel 5 is connected to the CPU 2 to form an output section of the CPU 2.
It forms the input section of CPU2.

The CPU 2 itself is connected to ROM 8, RAM 9, etc. to form a computer.
According to a program stored in advance in 8, predetermined operations are performed. In the figure, reference numeral 10 denotes a sensor interface, through which there are sensors for detecting blockage of the infusion tube, sensors for detecting air bubbles during liquid delivery, etc. that should interrupt the operation of the infusion pump. Various sensors are connected to detect the situation.

Next, the operation of the above embodiment will be explained. The operation/display panel 1 is designed to display displays as shown in Figures 2 to 7, and when the control device is turned on, the display as shown in Figure 2 first appears. It's becoming like that.

The computer with the CPU 2, ROM 8, and RAM 9 has various operating condition data registered in advance, and when the power is turned on, the most frequently used operating conditions are generally set as shown in Figure 2. The drive unit 3 is set so that the infusion pump operates under the displayed operating conditions.

When it is OK to start liquid feeding under these operating conditions, press the part 11 labeled "Start" on the operation/display panel 1 with your finger. Pressure on the portion 11 is detected by the transparent switch panel 5 and transmitted to the CPU 2, the drive unit 3 is operated, and liquid feeding is started.

When liquid feeding starts, the display on the operation/display panel 1 changes as shown in Figure 5, and displays information necessary for monitoring during liquid feeding, such as the cumulative amount of liquid fed 12 and the amount remaining until liquid feeding is completed. Time 13 is displayed and "Stop" is displayed.
14 is displayed. When you press the "stop" part 14 with your finger, the pressure is detected through the transparent switch panel 5, and the drive unit 3 can be stopped through the CPU 2. If you want to interrupt the liquid feeding, press the "stop" 14. It will become better.

On the other hand, if the operator wishes to change the liquid feeding conditions at the start of liquid feeding, press the portion 15 labeled "Change" in FIG. Pressure on the portion 15 is also detected via the transparent switch panel 5, and the operation/display panel 1 switches to a display as shown in FIG.

Therefore, for example, if you want to change the flow rate, press the area 16 labeled "Flow rate" with your finger. This press is also detected by the transparent switch panel, and the operation/display panel 1 is switched as shown in FIG. 4, and the portion 16 is displayed in inverted characters and the numeric keypad 17 is displayed. The transparent switch panel 5 in the area where the numeric keypad 17 is displayed will be functionalized so that it can be pressed, and by inputting the required flow rate value and pressing the "Set" part 18, the flow rate can be changed. is set. Once the setup is complete, you can

When you have finished changing the necessary conditions, press the part 22 labeled "Finish" in Figure 3, and the transparent switch panel 5 will detect the change, and the display in Figure 2 (the displayed numerical values for various conditions will be (changed) is done. Thereafter, the start and stop of the operation are the same as described above.

Various sensors are connected to the CPU 2 via a sensor interface 10, and if the sensor detects an abnormality during liquid feeding, the CPU 2 stops the drive unit 3, issues an alarm, and displays the display on the operation/display panel 1. also change.

For example, when it is detected that air bubbles have entered the liquid feeding tube, the flow changes as shown in FIG. Here, when the portion 23 labeled "mute" is pressed, the pressing of the portion 23 is detected and the alarm is interrupted. The operation/display panel 1 switches to the display shown in FIG.

Next, remove the abnormality detected by the sensor, and remove the part 2 labeled "Confirm" in Figure 7.
When you press 4, CPU2 recognizes that the abnormality has been resolved,
The operation/display panel 1 returns to its original display state (for example, the fifth
), and the operation of the drive section 3 is restarted.

Although the embodiments have been described above, the display items displayed on the operation/display panel 1 or the types of operation keys that are displayed and functionalized are not limited to the embodiments.

There are several types of infusion tubes used in this infusion pump, and each infusion tube has a certain cycle (for example, 1 cycle) of the infusion pump.
Conditions such as the amount of liquid to be delivered, bubble detection level, blockage detection level, etc. are stored in ROM8 in advance, and when using the infusion pump, the type of infusion tube to be used (product number, model number, etc.) must be specified. However, usable infusion tubes are not limited to those stored in the ROM8. When the infusion pump is operated, the physical quantities generated from each sensor, such as air bubble occlusion that occurs at that time, are input through the operation/display panel 1 as data such as air bubble detection characteristics and occlusion pressure change characteristics of the new infusion tube. It is also possible to calculate and determine the bubble determination level, occlusion determination level, etc., and the usable range of the infusion tube can be expanded without complicating the panel display of the operation/display panel 1.

Also, regarding the liquid feeding pattern, by registering various patterns in the ROM 8, such as normal liquid feeding (normal), intermittent liquid feeding, step liquid feeding, etc.
It is possible to easily set the liquid feeding pattern. Furthermore, in combination with external sensors, it is also possible to set fluid delivery in relation to heart rate and blood pressure.
In either case, when starting liquid feeding, the operation keys for the items necessary for the settings are displayed on the operation/display panel 1 and are made functional, so the panel display on the operation/display panel 1 is By using only the necessary items, you can prevent erroneous operations and make setting work easier.

Furthermore, regarding the amount of liquid to be fed, in addition to setting the amount of liquid to be fed per unit time, the total amount of liquid to be fed and the liquid feeding time (i.e.,
ml in minutes, etc.).

These can be freely controlled by a program for a computer consisting of CPU 2, ROM 8, and RAM 9, and the operation/display panel 1.
In addition, the operation keys necessary for setting conditions are displayed and functionalized, and while the infusion pump is being driven, necessary information regarding the judgment status is displayed.

(Effects of the Invention) According to the present invention, the operation of the infusion pump can be simplified and erroneous operation can be eliminated.

In addition, changing the conditions of the infusion tube, which was difficult to deal with in the past, can be easily handled by providing characteristic data and processing internally, which has the effect of eliminating restrictions on the use of the infusion tube.
