Clinical contrast injector for cardiovascular medicine department

Abstract

The invention discloses a clinical contrast injector for the cardiovascular medicine department, and relates to the technical field of medical instruments. The clinical radiography injector comprises a fixed seat, a clamping sleeve is fixedly mounted at one end of the top of the fixed seat, a needle cylinder is inserted in the clamping sleeve, a push rod is arranged in the needle cylinder, and a first clamping seat and a second clamping seat are arranged at the top of the fixed seat; and the first clamping seat is clamped with the end, away from the clamping sleeve, of the needle cylinder, the second clamping seat is clamped with the push rod, a cavity is formed in the fixed seat, and two rotating rods are arranged at the bottom of the cavity. By continuously holding and releasing the two rotating rods, a one-way rotating shaft can be driven to rotate in a one-way mode so as to drive a lead screw to rotate, then a threaded sleeve is in threaded connection with the lead screw, the second clamping seat is driven to move, control over the push rod is completed, the use resistance of the needle cylinder is gradually resolved, and suction and injection of contrast agent are easier.

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 diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction , cardiomyopathy, myocarditis and acute myocardial infarction and other cardiovascular diseases. [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.

Problems solved by technology

[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 viscous, and the injection is slow and laborious, like traditional syringes. When using one-handed injection, it is laborious and the injection is unstable. If the two-handed operation is used, one person cannot massage and clear the injection site well. Although some high-pressure automatic injectors can control the injection without manpower, they lack human-controlled injection. It is difficult to make corresponding injection control according to the actual situation during use, and thus has a certain degree of danger
