The present invention adopts three kinds of filter membrane material, as U.S. CUNO, Inc. company produces, be respectively the DELP film (to call the A film in the following text) with the affine adsorption function of liposome, 90SA and aperture 0.2um film (to call the C film in the following text) with mechanical filter function, the order of pressing A, B, A, C is superimposed, be placed in the dialysis cassette of a plastic casing formation, form and from a blood plasma, filter dialysis microgranule and liposome device.Again centrifugal plasma seperator (PCS2, U.S.'s blood corporate system), blood plasma pump and dialysis cassette are coupled together, form a complete therapy equipment.
Cerebral apoplexy patient is because blood plasma viscosity height mostly, a large amount of liposomees and other suspended particulates are arranged in the blood plasma, in the blood circulation flow process, when local condition changed, microgranule was reunited, and caused the blood vessel infraction, the present invention select for use the mechanical membrane filtration and or the compatible filtering method, reduce liposome and particle matter content in the blood plasma, thereby make blood vessel infraction symptom eliminate or alleviate, reach treatment and reduce the purpose of the clinical symptoms of cerebral apoplexy patient.
Mechanical filter is meant with the less various membrane materials in aperture liposome and microgranule is separated from blood plasma, the chemical composition of film must be a biologically inert, human body is not had toxic and side effects,, have a lot of commercial products available as cellulose, Kynoar, polysulfones etc.
Compatible filtering is meant the membrane filtration that liposome in the blood plasma and microgranule is had affinity with various, the film that contains silicon dioxide that is proposed as USP 4596660, have removal effect preferably for liposome, and for example the Positively charged membrane of USP2002019475 proposition all has intensive affine adsorption to various microgranules in the blood plasma.
