Title (EN) PLASMA SEPARATION DEVICE
(FR) DISPOSITIF DE SÉPARATION DE PLASMA
Abstract:
(EN) A device to separate plasma from a blood sample is disclosed, that allow extraction of plasma from whole blood directly into a tube/container or a fixed volume capillary. The plasma separation device consists of a membrane stack (39, 38 and 37), a flow director (36) spaced above the membrane stack to direct the flow of the sample over the membrane, a sample reservoir (34) to receive and hold blood sample, and spaced vertically above membrane stack, an inlet to introduce sample to the sample reservoir and outlet to extract the separated plasma spaced vertically below the membrane stack. The membrane stack comprises at least a first zone (39), a second zone (38), and a third zone (37) in sequence from top to bottom. The third zone (37) is a small pore filter matrix that also acts as a reservoir for the separated plasma.
(FR) L'invention concerne un dispositif pour séparer le plasma d'un échantillon de sang, qui permet l'extraction de plasma à partir de sang total directement dans un tube/récipient ou un capillaire de volume fixe. Le dispositif de séparation de plasma est constitué par un empilement de membrane (39, 38 et 37), un directeur d'écoulement (36) espacé au-dessus de l'empilement de membranes pour diriger l'écoulement de l'échantillon sur la membrane, un réservoir d'échantillon (34) pour recevoir et maintenir un échantillon de sang et espacée verticalement au-dessus de l'empilement de membrane, une entrée pour introduire un échantillon dans le réservoir d'échantillon et une sortie pour extraire le plasma séparé espacée verticalement en dessous de l'empilement de membrane. L'empilement de membrane comprend au moins une première zone (39), une deuxième zone (38) et une troisième zone (37) en séquence de haut en bas. La troisième zone (37) est une matrice de filtre à petits pores qui sert également de réservoir pour le plasma séparé.
