COMPLEX FOR CONDUCTION OF PLASMAPHORESIS WITH USE OF MEMBRANE PISTON FILTER AND VALVE OF UNIDIRECTIONAL FLOW Russian patent published in 2001 - IPC

FIELD: membrane plasmaphoresis. SUBSTANCE: complex for membrane plasmaphoresis has a system of one-time application and including plasmofilter of piston-filter type, proportioner of chamber type and valves of unidirectional flow, and apparatus ensuring functioning of all members of main line. Plasmofilter and proportioners have controlled chambers of variable volume. Apparatus has systems for control of plasmofilter and proportioners with preset pressure and flow rate with the aid of working medium of positive and negative pressures. Controlled chamber of each said member of main line is connected with respective control system of apparatus by hose. The invention also presents design of unidirectional flow valve. EFFECT: higher efficiency due to provision of highly effective and spare conditions of filtering. 11 cl, 18 dwg
