Title
(DE) BLUTBEUTELSYSTEM UND KASSETTE
(EN) BLOOD BAG SYSTEM AND CASSETTE
(FR) SYSTÈME DE POCHE DE SANG ET CASSETTE
Abstract
(EN) A blood bag system (10a) includes a BC pooling bag (54) for centrifugation of a buffy coat, a filter (56) for removing white blood cells from a supernatant liquid transferred from the BC pooling bag (54), a platelet preserving bag (58) for reserving the supernatant liquid that has passed through the filter (56), a first tube (60) connecting the BC pooling bag (54) and an inlet (56a) of the filter (56), a second tube (62) connecting the platelet preserving bag (58) and an outlet (56b) of the filter (56), and a cassette (50a) to be fixed in the centrifugation and separation apparatus. The first tube (60) and the second tube (62) are disposed within the cassette (50a). The cassette (50a) includes a first clamp section (106) for closing and opening the first tube (60), and a second clamp section (108) for closing and opening the second tube (62).
(FR) La présente invention concerne un système de poche de sang (10a) comprenant une poche de groupage BC (54) pour centrifugation d’une couche leucocyto-plaquettaire, un filtre (56) pour éliminer les leucocytes d’un surnageant liquide transféré depuis la poche de groupage BC (54), un poche de conservation de plaquettes (58) pour réserver le surnageant liquide qui a traversé le filtre (56), un premier tube (60) reliant la poche de groupage BC (54) et une entrée (56a) du filtre (56), un deuxième tube (62) reliant la poche de conservation de plaquettes (58) et une sortie (56b) du filtre (56), et une cassette (50a) à fixer dans l’appareil de centrifugation et de séparation. Le premier tube (60) et le deuxième tube (62) sont disposés dans la cassette (50a). La cassette (50a) comprend une première section de clamp (106) pour fermer et ouvrir le premier tube (60), et une deuxième section de clamp (108) pour fermer et ouvrir le deuxième tube (62).
