Single mechanical self-service syringe pump

Abstract

The invention discloses a single-person mechanical self-service injection pump. The pump comprises an injection pumpback device and an on-off device; the injection pumpback device comprises a shell, an injection mechanism and a pumpback mechanism; the shell is internally provided with a piston cavity, and the piston cavity is internally provided with a piston rod matched with the piston cavity; the injection mechanism is installed in an installing groove of the shell and used for automatically squeezing an injector installed on the injection mechanism; the pumpback mechanism is installed in amounting cavity of the shell and used for driving the piston rod to move; the injector on the injection mechanism and the piston cavity are communicated with the two input ends of the on-off device respectively, and through the on-off device, the on / off of the injector and the output end of the on-off device and the on / off of the piston cavity and the output end of the on-off device are controlled. By means of the pump, the trouble of adopting multiple people for cooperative operation in an operation process is reduced, the single-person operation ability of an attending doctor is improved, the operation time is shortened, and the working burden of medical staff is alleviated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a single-person mechanical self-service injection pump. Background technique [0002] In the past, clinical puncture was mostly performed by blind detection of anatomical landmarks, and there was great unpredictability of the curative effect and complications. complication. [0003] However, when performing a puncture operation, the chief surgeon often needs the assistance of an assistant, especially for ultrasound-assisted real-time positioning. The chief surgeon needs to hold the ultrasonic probe for positioning with one hand while the other hand inserts the puncture needle to reach the designated position. Hands are used to control drug injection and withdrawal, which requires the assistance of an assistant. Withdrawal is usually required before injecting the drug to verify that no blood vessels, voids, etc. have been punctured. In addition, if a small amount of liq...

AI Technical Summary

Problems solved by technology

In addition, if a small amount of liquid medicine needs to be injected to position the needle tip during the puncture, the surgeon cannot do it independently.

[0004] At present, there is no corresponding equipment on the market that can assist the surgeon to complete withdrawal and injection alone. During the operation, the assistant needs to cooperate to complete the operation, which results in a long operation time, and the surgeon and assistant need a certain tacit understanding. Affect the successful completion of the operation

Equipping assistants will also increase the number of personnel in the hospital, which is not conducive to saving manpower
