Cardiovascular medicine clinical angiograhic injector

Abstract

The invention relates to the technical field of medical instruments, and discloses a cardiovascular medicine clinical angiograhic injector. The injector comprises a needle cylinder, wherein a push rodwith one end penetrating through and extending into the needle cylinder is movably installed at the top of the needle cylinder, a right side piston is fixedly installed at the bottom of the push rod,and an injection needle is fixedly installed at the bottom of the needle cylinder. According to the cardiovascular medicine clinical angiograhic injector, during injection, a worker only needs to hold the needle cylinder with one hand and then presses a pressing rod with fingers, a connecting rod extrudes a moving rod, the moving rod moves downwards, then a rubber sealing block does not seal a vent hole any more, compressed air enters the needle cylinder to extrude the right side piston, the right side piston moves downwards, therefore injection of a contrast agent is achieved, in the whole injection process, the worker only needs to operate with one hand, the worker only needs to press the pressing rod in the operation process, and compared with a traditional pushing injection mode, theinjector is easier and more labor-saving, and injection is more stable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clinical imaging syringe for cardiovascular medicine. Background technique [0002] The Department of Cardiology is the Department of Cardiovascular Medicine. It is a clinical department set up by the major internal medicine departments of hospitals at all levels for the diagnosis and treatment of cardiovascular and vascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial Cardiovascular diseases such as infarction, cardiomyopathy, myocarditis and acute myocardial infarction. [0003] In the process of diagnosis and treatment of cardiovascular patients, it is often necessary to inject contrast medium for angiography of blood vessels, which is convenient for observation. Generally, a syringe is used for injection of contrast medium, but the contrast medium is relatively ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a clinical contrast syringe for cardiovascular medicine, which has the advantage of stable injection with one hand, and solves the problem that the contrast agent is relatively viscous, and the injection is slow and laborious. The injection is laborious and unstable, and if the operation is done with both hands, one person cannot massage and clear the injection site well. Squeezing and massaging around the injection site with fingers is conducive to the diffusion of the contrast agent and improves the comfort and stability of the injection.
