Abstract

Abstract Translated from French Dispositif de séparation des globules rouges du plasma sanguin. Il est constitué d'un conteneur souple (5), transparent notamment à la lumière artificielle, pour liquide sanguin ayant préalablement subi une centrifugation, un mors fixe (2) plan, vertical et un mors plan, incliné, mobile (3) à pivotement autour d'un axe de rotation horizontal, disposé à la base du mors fixe (2), le mors fixe (2) et le mors mobile (3) étant solidarisés par des moyens élastiques rappelant le mors mobile (3) vers le mors fixe (2), des moyens de maintien (11) du conteneur (5) en position verticale et fixe par rapport au mors vertical (2), des moyens d'émission (6) d'un faisceau lumineux traversant les parois (21, 21') du conteneur (5), le liquide sanguin. Les moyens d'émission (6) du faisceau lumineux sont fixes par rapport au conteneur (5) et par rapport à la paroi mobile (21) externe du conteneur (5) lors du déplacement du mors mobile (3) se rapprochant du mors fixe (2). Application à la transfusion sanguine. Device for separating red blood cells from blood plasma. It consists of a flexible container (5), transparent in particular to artificial light, for blood liquid having previously undergone centrifugation, a fixed jaw (2) plan, vertical and a plan jaw, inclined, mobile (3) pivotally around a horizontal axis of rotation, disposed at the base of the fixed jaw (2), the fixed jaw (2) and the mobile jaw (3) being secured by elastic means recalling the mobile jaw (3) towards the fixed jaw (2), means for holding (11) the container (5) in a vertical position and fixed relative to the vertical jaw (2), means for emitting (6) a light beam passing through the walls (21, 21 ') of the container (5), the blood liquid. The emission means (6) of the light beam are fixed relative to the container (5) and relative to the movable wall (21) external to the container (5) during the movement of the movable jaw (3) approaching the fixed jaw (2).
