A buckle 22 is installed in the middle of the top of the casing 1, a metal ring 23 is inserted through the top of the buckle 22, and a fixing clip 24 is connected to one edge of the metal ring 23. A viewing glass is embedded in the middle of the front of the casing 1. The main liquid storage bag 2. A scale bar is glued on the outer surface, an infusion tube 12 is connected to the bottom end of the double-pass joint 10, a filter 13 is sleeved on the outer surface of the top middle of the infusion tube 12, and the connection between the main liquid inlet 4 and the main liquid inlet pipe 5 is provided with a A sealing ring is installed at the connection between the infusion tube 12 and the filter 13 .

The working principle and use process of the present utility model: in the actual use process of the electronic double-capsule analgesia pump, the buckle 22 and the fixing clip 24 are used to clamp the device or hang it on a stable infusion stand, and the buckle 22 is used. The opening at the top corresponds to a stable infusion stand for hanging;

The medicinal liquid is injected from the main liquid filling port 4, and flows into the main liquid storage bag 2 through the main liquid inlet pipe 5. The outer surfaces of the main liquid storage bag 2 and the auxiliary liquid storage bag 19 are all bonded with scale bars. The remaining flow of the medicinal liquid is observed. After the first electric valve 6 is opened, the medicinal liquid enters the main drainage pipe 7 from the main liquid storage bag 2, and the first micro water pump 8 guides the medicinal liquid from the main drainage pipe 7 to the double-pass under the operation of the first micro-pump 8. In the joint 10, the medicinal liquid will flow through the second electric valve 9 on the way, and then the medicinal liquid will continue to be pushed to flow to the infusion tube 12, and the medicinal liquid will pass to the filter 13. After the medicinal liquid flows through the filter 13 to filter the impurities, the medicinal liquid is in The infusion tube 12 is outputted to the outside, and the throttling clip 11 installed on the infusion tube 12 can limit the flow rate of the medicinal liquid if necessary. The air pressure in the infusion tube 12 is reduced, so as to realize the current limiting effect of the throttling clip;

The liquid medicine injected from the second liquid inlet 21 flows into the auxiliary liquid storage bag 19 through the auxiliary liquid inlet pipe 20, and flows through the fourth electric valve 17 and the auxiliary drainage pipe 16 at the bottom of the auxiliary liquid storage bag 19. The two micro water pumps 15 lead to the two-way joint 10 under the operation of the third electric valve 14, and then go to the two-way joint 10. Therefore, during the dispensing process of the analgesic pump, the main liquid storage bag 2 and the auxiliary liquid storage bag 19 are independently independent. The medicine injection system injects the medicinal liquid in the analgesic pump into the main liquid storage bag 2 and the auxiliary liquid storage bag 19 respectively according to the function, physical and chemical properties, etc., and closes the third electric valve 14 and the fourth electric valve 17 during the infusion process, that is, The pipeline of the medicinal liquid from the auxiliary liquid storage bag 19 to the double-way joint 10 is temporarily blocked, and the medicinal liquid flows from the main drainage tube 7 between the main liquid storage bag 2 to the double-pass joint 10, and the medicinal liquid is a single injection at this time. The opposite is also true. When the electric valve is not closed, the injection liquid of the main liquid storage bag 2 and the auxiliary liquid storage bag 19 is in circulation. At this time, the liquid medicine belongs to mixed injection, and the electric valve is also divided into two parts in the process. There are three states of half-open and half-closed, open and closed, so during the infusion process, the mixing of the medicinal liquid can be adjusted by the state of the first electric valve 6, the second electric valve 9, the third electric valve 14 and the fourth electric valve 17. Injection and single injection, the main liquid storage bag 2 and the auxiliary liquid storage bag 19 are injected into the infusion tube 12 to inject the liquid medicine in stages, so as to complete the liquid delivery, and at the same time use the mechanical transmission method to generate positive pressure to achieve the output of the liquid medicine. It can prevent the backflow of the medicinal liquid. Before the medicinal liquid enters the infusion tube 12, there is air in the infusion tube 12, but the pushing process of the air is the same as the pushing process of the medicinal liquid, and one end of the infusion tube 12 is connected to the patient's body. , and the other end is connected to the double-pass joint 10, so that the medicinal liquid of the double-pass joint 10 is input into the patient's body to achieve analgesia.

Finally, it should be noted that the above is only a preferred example of the present utility model, and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
