<p>PURPOSE:To let blood platelets scarcely adhere on the inner surface of a bag, and thereby let the blood platelets in the bag be almost completely discharged out by letting two sheets of a bag be composed of polymer containing poly (ethylenebutylene) polystylene block mixed polymer, letting them, the inner surfaces of which are coarse, be piled up so as to be formed into the bag with the periphery sections of the sheets thermally welded. CONSTITUTION:A blood platelet preservation bag is composed of polymer containing poly (ethylenebatylene) polystylene block mixed polymer wherein two sheets forming a bag, the inner surfaces of which are coarse, are piled up in such a way that the periphery sections of the sheets are thermally welded. Since the bag is formed so that the periphery sections of the sheets are sealed, the sheets can be made thin and uniform in thickness so as to enable the bag to be available, which is excellent in gas permeability, flexibility and transparency. in addition, since the inner surfaces of the bag are made coarse, each of the inner surfaces will never be stuck together at the time of sterization, and blood platelets at the both end sections of the bag will never be delayed either in coming out later than those at the center section while eliminating difficulties in making sure of remaining blood platelets in the bag. The blood platelets in the bag can thereby be almost completely discharged out.</p> |
