Abstract

1481125 Tourniquets METEVE AB 14 Jan 1975 [14 Jan 1974] 1586/75 Heading A5R A cuff for restricting blood flow comprises transversely extending compartments 4 which are interconnected by valves so that they can be inflated in succession by gaseous medium supplied through a tube 2. The tube 2 may be connected to the lowest compartment 4 and each valve 5 may comprise a ball 12 held against its seat by a force regulatable by an adjusting screw 13. Gaseous medium is supplied to the lowest compartment until the pressure therein is sufficient to raise ball 12 so that the medium can flow through openings 18, 19 to the adjacent compartments. Tube 2 is supplied with gaseous medium via a reversal valve 20 to which an operating tube 3 is also connected. To deflate the cuff, valve 20 is set to connect tube 2 to atmosphere and supply gaseous medium to operating tube 3 which connects with a chamber 10 of each valve 5. A spring-loaded piston 14 is located within chamber 10 and carries a pin 15 to raise ball 12 when gaseous medium is fed into chamber 10. In a modification (Fig. 3a, 3b, not shown) the valves are located in the filling tube 2 which extends past all compartments 4 and operating tube 3 is omitted. In this embodiment each valve comprises an inlet and an outlet communicating with the tube 2, an outlet communicating with an associated compartment and an outlet to atmosphere, the setting of the valve being controlled by an apertured piston carried by a membrane and subjected to gaseous medium in tube 2.
