Abstract:
1. An integrated tourniquet system, comprising: an inflatable tourniquet cuff releasably connectable through a connector and tubing to a tourniquet pressure regulator, thereby establishing a gas passageway between the inflatable tourniquet cuff and the tourniquet pressure regulator; pressure sensing means for producing an indication of a level of pressure in the inflatable tourniquet cuff and gas passageway; user interface means for permitting a user to separately input a request to inflate the cuff and a request for initiation of a leakage test; wherein the tourniquet pressure regulator operates to regulate the level of pressure in the inflatable tourniquet cuff and gas passageway near a reference pressure level over a surgical time period suitably long for the performance of a surgical procedure; test means responsive to the request for initiation of the leakage test for disabling the operation of the tourniquet pressure regulator for a test period sufficient to perform a test to estimate a magnitude of leakage from the inflatable tourniquet cuff and gas passageway, and for enabling the operation of the tourniquet pressure regulator at the end of the test period, and for inhibiting the performance of the leakage test if the indication of the level of pressure is substantially different from zero at the time of the user request.
