Abstract

Cette invention a trait à une technique permettant de filtrer et de recueillir du sang ou des produits sanguins, laquelle technique consiste à filtrer le sang ou le produit sanguin à l'aide d'un dispositif de filtration (223), à recueillir le sang ou le produit sanguin dans une poche (294), à laisser le sang ou le produit sanguin dans une première longueur d'un tuyau aval (218), à mélanger le sang ou le produit sanguin dans la poche (294), à constituer, dans cette première longueur, un ou plusieurs compartiments hermétiquement fermés dans lesquels demeure le sang ou le produit sanguin, celui-ci ou ceux-ci devant être utilisé(s) pour des épreuves de la compatibilité directe, à transférer le sang ou le produit sanguin de la poche (294) dans une seconde longueur de tuyau (298) reliée à cette poche (294) et à constituer, dans cette seconde longueur, un ou plusieurs compartiments hermétiquement fermés dans lesquels demeure le sang ou le produit sanguin, celui-ci ou ceux-ci devant être utilisé(s) pour des épreuves de contrôle de qualité.
