INFUSION SYSTEM WITH IMPROVED CONTROL VALVE

A system and method for pressurizing bags of physiological fluids include a control valve (12) for providing deflation of a bladder (6) that compresses the bags. The toggle portion (22) of the control valve (12) is movable between a first and second position respectively for inflation and deflation...

Zusammenfassung:	A system and method for pressurizing bags of physiological fluids include a control valve (12) for providing deflation of a bladder (6) that compresses the bags. The toggle portion (22) of the control valve (12) is movable between a first and second position respectively for inflation and deflation of the bladder (6). When the toggle portion (22) is in the first position, the control valve (12) connects a source of pressurized air to the bladder (6), and when the toggle portion (22) is in the second position, the control valve (12) allows the bladder (6) to exhaust directly to the atmosphere through an outlet port (28) in the valve (12). The size of the outlet port is so large that it creates only very litttle resistance to the discharged air. L'invention concerne un système et un procédé permettant de mettre sous pression des poches de fluide physiologique au moyen d'une vanne de régulation (12), destinée à faire dégonfler une vessie (6) comprimant ces proches. La partie bascule (22) de cette vanne de régulation (12) peut passer d'une première à une seconde position, ces positions permettant respectivement de faire gonfler ou dégonfler ladite vessie (6). Lorsque cette partie bascule (22) se trouve dans la première position, la vanne de régulation (12) relie une source d'air sous pression à la vessie (6), et au moment où ladite partie bascule (22) passe dans la seconde position, la vanne de régulation (12) permet à l'air contenu dans ladite vessie (6) de s'évacuer directement dans l'atmosphère par l'intermédiaire d'un orifice de sortie (28), ménagé sur la vanne (12). La taille de cet orifice de sortie est si grande qu'elle ne crée qu'une faible résistance à l'air évacué.
