Plasma filtering device for treatment of acute cerebral infarction and method

Abstract

The invention provides a novel plasma filter device for treatment of acute cerebral infarction and filter method of the novel plasma filter device. The device comprises a shell and a filter element. The shell comprises an upper shell body and a lower shell body connected with the upper shell body. The upper shell body and the lower shell body form an accommodating space. The filter element is arranged in the accommodating space and comprises first filter films, a second filter film and a third filter film. The filter element is formed in the mode that the first filter film, the second filter film, the first filter film, the first filter film and the third filter film are arranged sequentially in the plasma flowing direction, wherein the first filter films are DELP films with a lipidosome and fibrinogen affinity adsorption function, the second filter film is an EKSP depth filtering film capable of adsorbing inflammatory factors and free radicals, and the third filter film is a 0.2 micrometer-thick film used for filtering out various granular substances with the hole diameter being greater than 0.2 micrometer. The novel plasma filter device for treatment of acute cerebral infarction and the filter method of the novel plasma filter device have the advantages that the plasma filter device can be used for filtering the plasma of an acute cerebral infarction patient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a new plasma filtration device and method for treating acute cerebral infarction. Background technique [0002] At present, cerebrovascular disease has become the first cause of disability and death among the urban and rural population in my country, and the incidence is increasing year by year. Epidemiological studies have shown that there are 1.5 to 2 million new stroke cases in China every year, the age-adjusted annual stroke incidence rate is (116-219) per 100,000 population, and the annual stroke mortality rate is (58-219) 142) / 100,000 population. [0003] In addition, there are more than 7 million patients with cerebrovascular diseases in my country, about 70% of whom are ischemic strokes, and a considerable proportion are accompanied by multiple risk factors, which are high-risk individuals for recurrent strokes. With the aging of the population, rapid economic development...

Problems solved by technology

However, through clinical observation and statistics, it is found that during the acute attack period of cerebral infarction, the proportion of patients with abnormally high blood lipid indicators is relatively low, but more inflammatory factors and free radicals will be produced during this attack period, while the existing filter device does not It cannot be proved that it has the function of filtering and removing inflammatory factors and free radicals; in addition, the vital signs of patients with acute cerebral infarction are unstable. Filter media with better performance and greater dirt holding capacity
