Problems solved by technology

[0009] According to the analysis of the existing thrombus aspiration catheters on the market, as well as the analysis of the published or authorized patented technologies, it is not difficult to find that the current aspiration catheters still have the following deficiencies: (1) The function is relatively single and can only be used Due to thrombus aspiration, thrombolysis cannot be performed at the same time; (2) Due to the use of braided or plastic tubes, it can only be used for larger blood vessels, such as coronary anterior branches, etc., and cannot be used for small blood vessels; (3) The composition structure is relatively complex, the production process is cumbersome, the production cost is high, and the operation is inconvenient for clinicians. Therefore, the development has a combination of thrombolysis and suction, and can be used in different parts and different diameters of blood vessels. At the same time, it has a simple structure, Convenient operation, low production cost, and convenient clinical use of suction catheters for thrombolysis and suction of thrombotic substances are of great significance for improving the health level and quality of life of our people.

Abstract

The invention relates to a suction catheter for thrombolysis and suction of thrombotic substance. The suction catheter comprises a central catheter, one end of the central catheter is connected with a suction connecting tube and an administration tube respectively, a liquid outlet of the suction connecting tube is connected with a middle tube, a liquid suction connecting head is arranged at each of two ends of the middle tube, the other end of the suction connecting tube is connected with a two-way valve, a liquid outgoing port end of the two-way valve is connected with a catheter joint, the other end of the catheter joint is connected with a rear-end suction catheter which is connected with a suction pump, a liquid incoming port end of the administration tube is connected with an administration one-way valve, and the other end of the administration one-way valve is connected with an administration injector. The suction catheter has the advantages of simple structure, convenience in operation, low manufacturing cost and convenience in clinical use.

Description

technical field [0001] The invention belongs to the technical field of therapeutic supplies, and in particular relates to a suction catheter for thrombolysis and suction of thrombotic substances. Background technique [0002] Thrombus is a small block formed by blood flow on the surface of the spalled or repaired part of the inner surface of the cardiovascular system. In the variable fluid-dependent type, the thrombus consists of insoluble fibrin, deposited platelets, accumulated white blood cells, and trapped red blood cells. Thrombus can be divided into arterial thrombus and venous thrombus according to the site of occurrence. Arterial thrombosis mainly occurs on the basis of atherosclerosis. The blood vessel wall of newborns is smooth and unobstructed. Since childhood, lipid-rich and Focal plaque of fibrous tissue, atherosclerosis does not affect blood flow in the early stage, but if the plaque is unstable and ruptures, it can activate platelets and form arterial thrombus...
