Title: SYSTEM AND METHOD OF CONTROLLING PRESSURE IN A SURGICAL TOURNIQUET
Abstract:
A system and method of controlling the pressure within a surgical tourniquet so as selectively to occlude blood flow within a portion of a limb of a patient, wherein the pressure within an inflatable cuff surrounding a portion of a limb of a patient is changed by automatically opening a first valve (116) connected to a controller (202) and located within a first conduit between an inflatable bladder (120) and the inflatable cuff (102), when the pressure in the inflatable cuff is different from that in the inflatable bladder. In another aspect, a system and method of controlling the pressure within a surgical tourniquet so as selectively to occlude blood flow within a portion of a limb of a patient within five seconds. In another aspect, a system and method of detecting a leak in a surgical tourniquet. In another aspect, a surgical tourniquet that, from an inflated state, may enter a deflated, set, default display or an off state.
