Positive-negative pressure automatic adjusting electric injection device with feeding function

Abstract

The invention relates to a positive-negative pressure automatic adjusting electric injection device with a feeding function. The positive-negative pressure automatic adjusting electric injection device comprises a shell, an injection pipe mounted on the shell and an injection push rod pushed into the injection pipe. The device further comprises a clamping control part, a torsion spring, a clampingpart and a power part, the clamping control part, the torsion spring and the clamping part are sequentially connected, the clamping control part is mounted on the shell to control the torsion springto generate torsion force to drive the clamping part to clamp the injection pipe, and the power part is mounted on the shell to drive the injection push rod to be pushed into the injection pipe at constant speed. The clamping control part on the device controls the torsion spring to generate torsion force to drive the clamping part to clamp the injection pipe, clamping is more stable and reliable,and feeding is convenient. Meanwhile, the power part can drive the injection push rod to be pushed into the injection pipe at constant speed, so that the device has a pushing assisting function and the feeding function at the same time, operation is easy and convenient, and the labor intensity of an operator can be effectively reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an electric injection device with automatic positive and negative pressure adjustment with a feeding function. Background technique [0002] At present, most of the syringes used in medical units are just ordinary syringes, which are simple in structure and single in function. When medical staff need to collect, dilute, and dispense liquid medicine, a large negative pressure will be generated in the injection tube, making the process of extracting the liquid medicine become easier. It is laborious and increases the time for collecting liquid medicine. When feeding liquid food or injecting medicine to the patient, a large positive pressure will be generated in the injection tube, and the operation is also laborious. Damaged skin and even chronic strain of tendons. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to ...
