A cerebral angiography contrast agent injector

Abstract

The invention discloses a cerebral vessel contrast medium injector. The cerebral vessel contrast medium injector comprises a handle, a rotating disc is fixedly connected to the left end of the handle,a rotating shaft is fixedly connected to the left side face of the rotating disc, two bearings sleeve the surface of the rotating shaft and are clamped to the left and right side faces of the inner wall of a shell respectively, the lower surface of the shell is fixedly connected with the upper surface of a fixing plate, a driving wheel is clamped to the surface of the rotating shaft and located between the two bearings and is in transmission connection with a driven wheel through a belt, the driven wheel is clamped to the surface of a threaded barrel, and the threaded barrel is clamped to theleft side face of the inner wall of the shell. The cerebral vessel contrast medium injector has the advantages that through the cooperation of the handle, the rotating shaft, the driving wheel, the belt, the driven wheel, the threaded barrel, a threaded column, an injector body, a baffle, a stop block, a telescopic rod, springs, a through hole and a spongy cushion, the purpose of fixing the injector is achieved, and thus the work of doctors and patients is facilitated.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a cerebral angiography contrast agent injector. Background technique [0002] Medical interpretation in Chinese: 1. Healing, 2. Treatment of diseases. The history of Chinese medicine has been around for thousands of years, but this term has only appeared in the past few decades. In fact, it is a new term to be in line with international standards. It was mostly used for treatment before. However, medical care also includes health care content. [0003] In the process of injecting the contrast agent into the syringe, air is often sucked in, but the air cannot be injected into the body. If the injected air reaches a certain amount, it is easy to form an air embolism and cause life-threatening danger to the patient. The invention with the patent number CM107583143A is effective. The above problems have been solved, but most of the syringes have no fixed function, and the medical ...
