Liquid extractor for high-pressure radiography injector

Abstract

The invention belongs to the field of medical equipment and apparatuses, and particularly relates to a liquid extractor for a high-pressure radiography injector. The liquid extractor comprises a high-pressure radiography injector needle cylinder, a piston arranged in the high-pressure radiography injector needle cylinder, an injector installation fixing seat, a connecting component, a rack, a rackfixing seat and a pushing rod, the injector installation fixing seat fixedly sleeves the tail end of the high-pressure radiography injector needle cylinder, and the high-pressure radiography injectorneedle cylinder is installed at and fixed to the left side of the rack through the injector installation fixing seat and the connecting component; a first sliding rail is transversely and horizontally arranged above the front side face of the rack, a sliding rail is longitudinally and vertically arranged on the position, below the first sliding rail, of the rack, one end of the pushing rod is inclamping connection with the piston mutually and cooperatively, and the other end of the pushing rod is fixed to the middle of the connecting rod through a first pin column. Through the structure design of the liquid extractor, a handle can be rotated manually to complete the liquid extracting operation, the efficiency of the liquid extracting operation is ensured, working intensity of medical workers is reduced, and the operation is convenient, safe and reliable.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a liquid pump for a high-pressure radiography syringe. Background technique [0002] Clinically, during the treatment of cardiovascular diseases, such as coronary angiography and left heart angiography for the clinical treatment of congenital heart disease and rheumatic heart disease, when injecting contrast medium, in order to accurately understand the condition of the patient's blood vessels, it is necessary to inject the contrast medium Bolus injection into the blood vessel for imaging. At present, the pumping and injection of the existing contrast agent are all done on the CT imaging equipment. Each time the liquid is pumped, due to the viscosity of the contrast medium, the pumping time is long and the efficiency is low. The operation is very troublesome, time-consuming and labor-intensive, which brings great work difficulty to medical staff and increases the wait...
