Abstract
This invention relates to a new control valve intended to be used to control the supply and exhaust of fluids to a dual tourniquet system. The tubes supplying and exhausting the tourniquets are of a flexible nature, and as such may be squeezed to stop the flow of fluids therethrough. The inventive valve includes cam members with camming projections formed thereon at various predetermined positions on the circumferences thereof. Simultaneous rotation of the cam members by a control knob results in sequential filling and emptying of the tourniquets in a predetermined sequence. The valve is especially useful in the practice of the Bier block procedure.
