A double-head cardioplegia perfusion device

Abstract

The invention belongs to the technical field of medical equipment, and specifically relates to a double-head cardioplegia perfusion device, which includes a perfusion bag, an infusion tube and a fixed valve; the fixed valve is designed in an arc-shaped plate shape; the fixed valve has an arc-shaped opening One side is provided with a symmetrically designed first chute; the adjacent sides of the two first chute are fixedly connected with springs; one side of the arc-shaped opening of the fixed valve is elastically connected with a clamping plate through the first chute ; The clamping plate is symmetrically designed; the corresponding clamping plate of the fixed valve is provided with a first through groove; the clamping plate is fixedly connected with an auxiliary handle; The elastic limit connection between the rubber pad in the first groove and the infusion tube makes the connection between the infusion tube and the fixed rail and the support rail fixed, and the angle that can be changed arbitrarily between the multi-section support rails is effective Limit and guide the infusion tube until the infusion tube extends into the surgical field of view.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a double-head cardioplegia perfusion device. Background technique [0002] In the prior art, it is often necessary to control cardiac arrest by infusing cardioplegic fluid during cardiac surgery, and then perform cardiac surgery. Myocardial protection is important during cardiac arrest. During the perfusion process of cardioplegia, perfusion bags and perfusion tubes are needed, and the perfusion tubes are prone to displacement when subjected to external force. There is a certain impact force, so in the process of perfusing cardioplegia, it is necessary to hold the perfusion tube with proper force by hand so as to avoid the gap between the perfusion tube and the opening of the coronary artery from expanding, causing the cardioplegia to leak and cannot be effectively delivered to the coronary artery. Intracardiac perfusion is not conducive to myocardial protection. [00...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, most of the infusion tubes in the prior art are made of soft materials. When infusing cardioplegic fluid into the heart, it is not only easy to be affected by external factors and shake, but also its delivery route is not easy to fix. The problem of inconvenient use in the surgical environment, a double-head cardioplegia perfusion device proposed by the present invention
