Abstract

The invention belongs to the technical field of medicine perfusion, and discloses an intracoronary micromembrane balloon drug perfusion system and a control method thereof. An inflation cavity is formed between a balloon inner membrane and a balloon middle membrane, the balloon middle membrane and a balloon outer membrane are medicine perfusion cavities, a medicine conveying rod pipe is connectedto a medicine filling cavity, a medicine conveying valve is arranged on a medicine conveying rod pipe, a balloon air cavity inflation hole is formed in the inflation cavity, the balloon air cavity inflation hole is connected with a balloon inflation tube, a balloon inflation valve is arranged on the balloon inflation tube, the inner side of the balloon inner membrane is a central hollow eccentricpipeline, the outer side of the central hollow eccentric pipeline is a central hollow eccentric pipeline telecentric end, and the right end of the central hollow eccentric pipeline telecentric end isa central hollow eccentric pipeline proximal end. After the balloon is expanded, the central eccentric pipeline can still guarantee forward blood flow in the coronary artery, the forward blood flow isnot hindered, the blood supply of the far section of the coronary artery is guaranteed, and the purpose of inhibiting intimal hyperplasia of blood vessels can be achieved.

Description

technical field [0001] The invention belongs to the technical field of drug infusion, and in particular relates to a drug infusion system and a control method of a micromembrane balloon in a coronary artery. Background technique [0002] With the change of dietary structure, coronary heart disease has become the most common cardiovascular disease and one of the primary diseases threatening the lives of our people. Interventional diagnosis and treatment of coronary heart disease has become the most common and effective means. Interventional technology has changed from simple balloon dilatation to bare metal stent implantation and then to drug-coated balloon, which has significantly improved the treatment effect and prognosis of coronary heart disease. However, drug-eluting stent implantation still cannot avoid the stenosis caused by intimal hyperplasia. Therefore, the drug-coated balloon was derived. Compared with the traditional balloon, the drug carried by the drug balloo...
