BAG AND DEFIBRINATION METHOD USING A TEXTILE ELEMENT

摘要

Pouch (1) designed for defibrination of a biological fluid such as blood or blood plasma, comprises an external envelope (2) forming an internal volume (6) for the fluid. The envelope has an inlet (7) and an outlet (8) for the fluid. A textile element (9) designed to fix fibres in the fluid is placed in the internal volume without subdividing it. Pouch (1) designed for defibrination of a biological fluid such as blood or blood plasma, comprises an external envelope (2) forming an internal volume (6) for the fluid. The envelope has an inlet (7) and an outlet (8) for the fluid. A textile element (9) designed to fix fibres in the fluid is placed in the internal volume without subdividing it. The textile element includes at least one knitted, woven or non-woven layer and is made from a polymer or copolymer based on polyethylene, polypropylene, polyester, polyamide, polyurethane and their derivatives. The external envelope is made of two leaves (3, 3') of supple plastic material which are assembled around their periphery. The textile element is fixed on one part of the periphery of the internal volume. Independent claims are also included for the following: (1) a system of pouches designed for the sampling and defibrination of a biological fluid such as blood or blood plasma, containing a primary fluid receiving pouch with a textile element as described above. A second fluid receiving pouch is connected to the outlet from the primary fluid receiving pouch by a second pipe which contains a filter which can retain microclots; and (2) a defibrination process using a pouch containing a textile element as described above, with the pouch agitated for a period allowing the elimination of effectively all the fibre in the fluid. The defibrinated fluid may be transferred to a second pouch which is connected to the first by sealed and sterile means. The agitation is stopped to allow the defibrinated blood to be decanted to separate the blood serum and the blood cells.
