Shearing-type infusion squeezing device

Abstract

The invention discloses a shearing-type infusion squeezing device. The device comprises a squeezing device, a pressure driving device and an infusion device, the squeezing device is composed of a fixing plate, a moving plate hinged to the fixing plate, a pressure driving device is fixed to the outer side of the fixing plate, a gravitational force balancing device is arranged at the bottom of the outer side of the fixing plate and is composed of an L-shaped hanging panel, a ball hinge A, a ball hinge B, a connecting rod and a heavy hammer, one face of the L-shaped plate is fixed to the fixing plate, the other face is suspended on the ball hinge A, the bottom of the ball hinge A is rotatably connected with the top of the ball hinge B, the bottom of the ball hinge B is rotatably connected with the top of the connecting rod, the bottom of the connecting rod is fixed to the heavy hammer, and a Murphy's dropper is fixed to the connecting rod through a clamping hoop. According to the device,infusion liquid is squeezed in a shearing-type progressive squeezing manner, the infusion liquid does not need to be hanged high, the Murphy's dropper is allowed to be always in a perpendicular statethrough the cooperation of the ball hinge A, the ball hinge B and the heavy hammer, the observation of the dripping speed of medicinal liquid is convenient, and the dripping speed is further controlled through a speed regulator.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a scissor type infusion extrusion device. Background technique [0002] Intravenous infusion is a method of injecting a certain amount of sterile solution and medicine into the human body through the vein by using atmospheric pressure and gravity. It is an important treatment method to improve health status and save lives clinically. The current conventional method for infusion is to hang the injection on the hook, the suspension height is higher than the position where the infusion needle is inserted into the patient's vein, which requires relatively high space requirements, and when the patient is transported on a stretcher, an auxiliary person is often required to carry the injection. And as the stretcher tilts or swings in the process of transporting the patient, the Murphy's dropper used to observe the drop rate of the drug solution during the infusion cannot always be in a ve...

Problems solved by technology

[0003] The purpose of the present invention is to provide a scissor-type infusion extrusion device, which overcomes the defects of the prior art and solves the problem that the Murphy's dropper, which needs to be hung high for the injection, cannot always be in a vertical state, and cannot observe the process of transporting the patient on a stretcher. The problem of the drop rate of Chinese medicine in Murphy's dropper
