[0040] Display screen 2 is used to display the drug ratio and drug concentration in real time.

[0041] The processor is used to calculate the rotation speed of each peristaltic pump 13 according to the set drug concentration and drug ratio and send instructions to the controller.

[0042] The controller is used to control the rotation speed of each peristaltic pump 13 according to the instructions sent by the processor; and when the controller receives the signal from the bubble sensor 14, it will immediately stop all peristaltic pumps 13 and send a signal to the processor, and the processor will display a prompt to add medicine on the display screen 2.

[0043] Since the present embodiment uses a peristaltic pump 13 and a bubble sensor 14, the infusion tube 15 only needs to pass through the peristaltic pump 13 and the bubble sensor 14, so that there will be no drug residue in the peristaltic pump 13 and the bubble sensor 14, and there is no need to clean the peristaltic pump 13 and the bubble sensor 14. Only the disposable infusion tube 15 needs to be replaced each time the preparation is performed. Each peristaltic pump 13 has a separate switch, and the start and stop of each peristaltic pump 13 can be controlled by the separate switch, and the start and stop button 9 can also be used to control all peristaltic pumps 13 to start and stop according to the speed calculated by the processor.

[0044] like Figure 2 As shown, in this embodiment, the peristaltic pumps 13 are set as No. ① to No. ⑤ from left to right, and the control system of the dispensing instrument 1 is also provided with No. ① to No. ⑤ drugs, and No. ① to No. ⑤ drugs correspond to No. ① to No. ⑤ peristaltic pumps 13 respectively.

[0045] The method of using the multi-formula analgesic drug dispensing device is as follows: taking the formula of "sufentanil 0.1ug / ml+butorphanol tartrate 0.1mg / ml+palonosetron 2.25ug / ml" as an example for explanation, the volume of the analgesic pump box is 150ml.

[0046] First, the medical staff prepares sufentanil, butorphanol tartrate, and palonosetron into dilute drugs of constant concentration using physiological saline, and hangs the diluted sufentanil, butorphanol tartrate, and palonosetron on the infusion stand 19 through three solvent bottles 18, respectively, selects the infusion tube 15 with three branch pipes 17, and inserts one end of the three branch pipes 17 into the three solvent bottles 18 respectively, and the other ends of the three branch pipes 17 are stuck in the three pipe grooves 3 corresponding to the peristaltic pumps 13 from left to right, and starts to exhaust the infusion tube 15, turns off all bubble sensors, presses the start-stop button 9 to make the peristaltic pump 13 transport the three drugs to the end of the main pipe 16 away from the branch pipe 17, and connects the end of the main pipe 16 away from the branch pipe 17 to the analgesic pump box through a rotary joint;

[0047] Press the on / off key 4 to turn on the dispensing device 1, press the capacity setting key 8, use the numeric key 11 to input the capacity of 150 ml, and press the confirmation key 10 to complete the capacity setting;

[0048] If the formula is a fixed formula that has been set, press the fixed formula key 7 to enter the fixed formula selection interface, and select the fixed formula through the selection key 12 and the confirmation key 10; press the concentration setting key 5, input the diluted drug concentration of the aforementioned sufentanil, butorphanol tartrate, and palonosetron, and press the confirmation key 10 to complete the concentration setting; the processor will now calculate the speed of each peristaltic pump 13 according to the currently set drug concentration and drug ratio, and calculate the working time of the peristaltic pump 13 according to the input capacity and the speed of each peristaltic pump 13. After pressing the start-stop key 9, the processor sends an instruction to the controller, and the controller controls the operation of each peristaltic pump 13 according to the speed and working time of the peristaltic pump 13 calculated by the processor. Since there are only three types of drugs, the controller will only control peristaltic pumps 13 No. 1 to 3 to work.

[0049] If the formula is not a fixed formula that has been set, the fixed formula selection interface can be entered through the fixed formula key 7, and a fixed formula with only three drugs, sufentanil, butorphanol tartrate, and palonosetron, can be selected through the selection key 12 and the confirmation key 10; press the formula adjustment key 6, use the selection key 12 to select the drug whose ratio needs to be adjusted, use the number key 11 to enter the ratio of the drug, and press the confirmation key 10 to complete the adjustment of the drug ratio; press the concentration setting key 5, enter the diluted drug concentration of the aforementioned sufentanil, butorphanol tartrate, and palonosetron, and press the confirmation key 10 to complete the concentration setting; the processor will now calculate the speed of each peristaltic pump 13 according to the currently set drug concentration and drug ratio, and calculate the working time of the peristaltic pump 13 according to the input capacity and the speed of each peristaltic pump 13. After pressing the start-stop key 9, the processor sends an instruction to the controller, and the controller controls the operation of each peristaltic pump 13 according to the speed and working time of the peristaltic pump 13 calculated by the processor.

[0050] When the bubble sensor detects that there is no medicine in the infusion tube, it will send a signal to the controller. After receiving the signal, the controller will immediately stop the operation of all peristaltic pumps 13 and send a signal to the processor. The processor will display a prompt to add medicine on the display screen 2. After replacing the new solvent bottle 18, there will be a small amount of air in the corresponding infusion tube 15. At this time, the corresponding peristaltic pump 13 can be turned on by turning on the separate switch of the peristaltic pump 13 to control the rotation of the peristaltic pump 13. After the small amount of air in the corresponding infusion tube 15 is discharged into the analgesic pump box, the peristaltic pump 13 is turned off by the separate switch, and then the start-stop button 9 is pressed. All peristaltic pumps 13 continue to work according to the speed and working time calculated by the processor. At present, a small amount of gas is allowed to enter the analgesic pump box during clinical preparation, and artificial exhaust can be performed after the analgesic is prepared.

[0051] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
