Abstract

The invention discloses an easy-cleaning interventional injector for cardiovascular treatment. The easy-cleaning interventional injector comprises a fixing frame, a connecting plate and a fixing plate, a push rod is arranged on the fixed frame; a piston is arranged in an injection tube; the injection tube is fixed to the fixing frame, a connecting plate is arranged on a fixed sleeve rod, a first circular gear is installed on the connecting plate, a scraping rod is fixed to the first circular gear and arranged in the injection tube, a second circular gear is connected to the first circular gear, and the second circular gear is arranged on the connecting spring. The easy-cleaning interventional injector for cardiovascular treatment is provided with the scraping rod, under the action of the second circular gear, the first circular gear can drive the scraping rod to rotate, and when the fixed sleeve rod moves downwards, under the action of the connecting plate, the scraping rod rotates andmoves downwards at the same time, a contrast media attached to the interior of the injection tube can be removed, and the use efficiency of the injector is improved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an interventional injector for cardiovascular treatment that is easy to clean. Background technique [0002] Cardiovascular interventional therapy is a new technique for diagnosing and treating cardiovascular diseases. By injecting media such as contrast agents into blood vessels with a syringe, the heart and large blood vessel cavities can be easily visualized and observed under X-ray irradiation, thus facilitating the diagnosis and treatment of cardiovascular diseases. Cardiovascular disease diagnosis. [0003] However, most of the interventional injectors for cardiovascular treatment now have the following problems: [0004] 1. The contrast agent medium injected by the injector is relatively viscous, and will remain on the inner wall of the injection tube after use, making it difficult to clean; [0005] 2. Since the contrast agent medium is relatively viscous, an...
