Abstract

The present invention relates to a coronary heart disease treatment filter, which comprises a shell, wherein the top portion of the shell is respectively provided with a blood inlet and a gas discharging port, the bottom portion of the shell is provided with a blood outlet, a filtration layer is arranged in the shell and comprises three layers of carbon membranes with a pore size of 0.35-0.55 [mu]m and a layer of a polyethersulfone filtration membrane with a pore size of 0.2 [mu]m from top to bottom, the thicknesses of the three layers of the carbon membranes are the same, the thickness of each layer of the carbon membrane is 5 mm, and a thickness ratio of the single-layer carbon membrane to the polyethersulfone filtration membrane is (7-10):1. According to the present invention, the bloodviscosity can be effectively reduced through the extracorporeal circulation of blood.

Description

technical field [0001] The invention relates to a medical device, in particular to a filtering device for coronary heart disease. Background technique [0002] Coronary heart disease is a common and frequently-occurring disease in clinical practice. According to modern medicine, coronary heart disease is caused by coronary atherosclerosis or thrombus attached to the wall of the coronary artery, resulting in narrowing of the coronary artery and reducing blood flow through the coronary artery. When the heart load suddenly increase, blood demand increases, exceeds the compensatory capacity of coronary blood supply, or blood demand does not increase, but coronary spasm, reduced blood flow, or the presence of the above factors at the same time, can cause rapid heartbeat, temporary ischemia, ischemia, etc. Oxygen causes angina pectoris. There are various methods for treating coronary heart disease at home and abroad, including dilating coronary arteries and preventing thrombus fo...
