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 tourniquet comprising: (a) an occlusive band for encircling a limb of a subject and for applying pressure to the limb wherein an inner surface of at the band faces the limb; and applied pressure sensing means located at a predetermined position on the inner surface of the band for producing an indication of the pressure applied by the band to the limb near the predetermined location. The applied pressure sensing means is comprised of material having a degree of flexibility and physical dimensions selected so that the sensing means conforms closely to the surface of the occlusive band and does not substantially displace the surface of the limb away from the band surface. The applied pressure sensing means produces an applied pressure signal representative of the pressure applied by the band to the limb near the predetermined location, the occlusive band is responsive to a varible pressure control signal, and pressure-regulating means responsive to the applied pressure signal is included for producing a pressure control signal to maintain the pressure applied by the band to the limb near a predetermined reference pressure.

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.

Abstract: A source of pressurized gas is attached to a dynamic pressure wave appliance. The pneumatic control circuit connects the source of pressurized gas to a first chamber of the appliance. When the pressure in the first chamber reaches a first predetermined level, a valve seals the first chamber and connects the source so as to inflate a second chamber about the first. When the pressure in the second chamber reaches a second predetermined level, a valve permits the first chamber to deflate while continuing to connect the second chamber for inflation. A valve for sealing the inflated sleeve discontinues the inflation of the sleeve when the pressure therein reaches a third predetermined level. The sequence of operation of the pneumatic control circuit will cause a suitable dynamic pressure wave appliance to apply a pressure to a human or animal extremity which begins at the most distant end and travels up the extremity in the nature of a pressure wave.
