Abstract

Dispositif d’inversion des flux sanguins pour circuit d’épuration extra rénale. L’invention concerne un boitier qui comporte deux compartiments circulaires, un grand (4) contenant deux chambres (5a) et (5b) séparées par une cloison étanche (3) et un petit (15) contenant une chambre circulaire (8), un disque rotatoire (6) et un système d’inversion des flux (10). Le mode inversion des flux est activé par la rotation du disque (6) par le support (13) dans le sens inverse des aiguilles d’une montre induisant l’ouvertures des orifices (11a, 11b, 11c, 11d) et la connexion des prolongations (12a, 12b, 12c, 12d) aux connexions (1a, 1b, 1c, 1d). Les clamps (9), la tubulure Y (2) et les deux sorties (7a, 7b) permettent la purge du dispositif. Le mode uniponction se fera par la rotation du système (10) par le support (14) dans le sens des aiguilles d’une montre du dispositif activé en mode inversion des flux. Figure pour l’abrégé : Figure 1Blood flow reversal device for extra-renal purification circuit. The invention relates to a housing which comprises two circular compartments, a large one (4) containing two chambers (5a) and (5b) separated by a watertight partition (3) and a small one (15) containing a circular chamber (8), a rotary disk (6) and a flow reversal system (10). The flow inversion mode is activated by the rotation of the disc (6) by the support (13) in the counterclockwise direction inducing the opening of the orifices (11a, 11b, 11c, 11d) and the connection of the extensions (12a, 12b, 12c, 12d) to the connections (1a, 1b, 1c, 1d). The clamps (9), the Y tubing (2) and the two outlets (7a, 7b) allow the device to be purged. The unipuncture mode will be achieved by rotating the system (10) by the support (14) in a clockwise direction of the device activated in flow reversal mode. Figure for abstract: Figure 1
