Problems solved by technology

[0003] At present, medical staff use syringes to inject contrast media into patients manually. During the injection process, medical staff cannot uniformly control the flow rate of contrast media. When the flow rate of contrast media is too fast, it is easy to Increase the suffering of patients during treatment. In view of the above defects, it is necessary to design a booster device for cardiovascular imaging

Abstract

The invention discloses a bolus injection assisting device for angiocardiography. The bolus injection assisting device comprises a sleeve, a liquid drainage mechanism, a push plate, a push rod, a linkage mechanism, a connecting sleeve, a driving mechanism, a lithium battery and a graduated scale. The bolus injection assisting device for angiocardiography can rapidly inject an amount-controlled contrast agent into a patient at a constant flow rate, thus avoiding that the pain of a patient during treatment is intensified due to the flow rate is over-high, and therefore, it can be seen that, thepain of the patient during treatment is effectively relieved by using the device of the application.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a booster device for cardiovascular imaging. Background technique [0002] Cardiovascular angiography is to quickly inject contrast agent into the heart cavity or blood vessel through the cardiac catheter, so that the heart and blood vessel cavity can be visualized under X-ray irradiation. The development process is photographed, and the blood flow sequence containing the contrast agent and the filling of the heart vessels can be seen from the results of the development, so as to understand the physiological and anatomical changes of the heart and blood vessels. It is a valuable method for diagnosing cardiovascular disease. [0003] At present, medical staff use syringes to inject contrast media into patients manually. During the injection process, medical staff cannot uniformly control the flow rate of contrast media. When the flow rate of contrast media is too fast,...
