Abstract: Apparatus for monitoring the patency of tubing in a pneumatic medical device including: an inflatable appliance for positioning onto the surface of a limb and adapted to apply pressure to the limb beneath the appliance when inflated with gas; tubing for establishing a pneumatic conduit between the inflatable appliance and a pressure control system. The pressure control system for supplies the tubing with gas at a controlled pressure. The pressure control system includes a pulse generating system for generating a pneumatic pulse at a sensing location in the tubing by producing a variation in the pressure of the gas at the sensing location during a finite time interval. A tubing patency monitoring system is adapted to sense the variation of pneumatic pressure at the sensing location and produce a tubing obstruction signal when the variation of pneumatic pressure sensed after the finite time interval exceeds a reference level.

Abstract: A pneumatic tourniquet for maintaining occluded or restricted blood flow into a patient's limb includes an inflatable cuff, a pressurizing mechanism for pressurizing the cuff, a pressure relief mechanism for depressurizing the cuff, a blook pressure sensing mechanism for sensing the patient's systolic blood pressure and for producing a blood pressure output signal representative thereof, and a pressure regulator mechanism responsive to the blood pressure output signal for selectably activating the pressurizing mechanism and the pressure relief mechanism to maintain a substantially constant pressure difference between the cuff pressure and the patient's systolic blood pressure.Thus, the cuff pressure may be varied "adaptively" in response to changes in the patient's intra-operative systolic blood pressure to pressurize the cuff close to the minimum level required to maintain a bloodless surgical field, thereby minimizing the risk of patient injury due to over-pressurization of the cuff.
