Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and in particular relates to an easy-to-use push injector for cardiovascular angiography. Background Art

[0002] In the actual consultation process of the cardiovascular department, it is necessary to use X-ray machines and other examination equipment to conduct in-depth examinations of patients. Traditional X-ray machines need to inject contrast agents for patients who are unconscious or unable to take contrast agents orally when taking pictures. After searching, the application number "CN202111512710.9" discloses "a pusher for cardiovascular imaging", which records "provided with a medicine barrel, a threaded connector, a stirring roller, and a one-way coupling, the contrast agent in the medicine barrel is pre-stirred before entering the injection barrel, further improving the fluidity and uniformity of the contrast agent, and improving the injection effect; at the same time, the one-way coupling allows the piston disc to be screwed in and injected only when the driving mechanism rotates counterclockwise." By using the medicine barrel, the threaded connector, the stirring roller, and the one-way coupling, the contrast agent in the medicine barrel is pre-stirred before entering the injection barrel, which can indeed further improve the fluidity and uniformity of the contrast agent and improve the injection effect;

[0003] Compared with this application, this patent does not have the function of electric pushing and cannot achieve the effect of stable pushing:

[0004] However, there are still the following problems in actual use:

[0005] 1) Manual rotation injection is not stable enough. When rotating the knob, the user rotates the knob with different strengths, which results in different doses of contrast agent injected, causing discomfort to the patient.

[0006] 2) When preparing for the injection, if the injection dose is insufficient, it is impossible to quickly inject again, resulting in poor results of the imaging, which affects the doctor's judgment and increases the workload.

[0007] Based on this, it is extremely practical to provide a push injector that can be electrically pushed and can quickly replace the push injector for re-injection. Utility Model Content
