Abstract

The invention relates to an eyeground artery occlusion treatment filter. The treatment filter comprises a shell; a blood inlet and an exhaust hole are formed in the top of the shell; a blood outlet isformed in the bottom of the shell; a filtering layer is arranged in the shell; the filtering layer comprises two layers of carbon films with hole diameters of 0.4-0.5[mu]m and a layer of polyether sulfone filtering film with the hole diameter of 0.2[mu]m from top to bottom; the two layers of the carbon films are same in thickness which is 5mm for each layer; and a thickness ratio of the single layer of carbon film to the polyether sulfone filtering film is (9-12) to 1. Through blood extracorporeal circulation, the blood viscosity is lowered effectively.

Description

technical field [0001] The invention relates to a medical device, in particular to a filter device for fundus artery blockage. Background technique [0002] "Ocular fundus arteriosclerosis" is a common chronic retinal vascular change in the elderly over 60 years old. As the age increases, the incidence rate also increases, about 40%-80%. The main manifestations are thinner retinal arteries, lower transparency, lighter color, strong reflection, straight blood vessels, and sharp-angled branches. Currently, there is no effective treatment. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a treatment filter for fundus artery occlusion that can effectively reduce blood viscosity for patients through extracorporeal circulation of blood. [0004] Technical solution: In order to solve the above-mentioned technical problems, the treatment filter for fundus artery occlusion accord...
