  • Patent number: 11944322
    Abstract: A tourniquet apparatus comprises a cuff, a user interface, a controller, a protocol hazard key and a protocol safety interlock. The cuff encircles the patient's limb and applies a level of pressure. The UI presents a protocol symbol from a plurality of protocol symbols wherein each protocol symbol is indicative of a corresponding safety protocol. The controller is responsive to stored pressure levels and stored times specified by the safety protocol, after any adjustments by the user, and operable during the stored protocol time period for maintaining the level of pressure applied by the cuff to the individual patient near the plurality of stored pressure levels at the plurality of stored times. The protocol hazard key is actuatable to end the stored protocol time period while the controller is operable. The protocol safety interlock prevents selection of a second protocol symbol while the controller is operable.

    Abstract: An automatic tourniquet apparatus comprises a tourniquet cuff, a pressure transducer, a user interface, a patient hazard shield and a pressure regulator. The pressure transducer produces a cuff pressure signal. The user interface produces a reference pressure signal. The patient hazard shield is responsive to the cuff pressure signal and the reference pressure signal, and operable during a regulation time period to produce a patient hazard signal if, in one implementation, a current level of pressure in the tourniquet cuff is greater than the reference level of pressure by at least a predetermined overpressure limit. The pressure regulator is responsive to the patient hazard signal, and has a pressurizing element for increasing pressure in the cuff and a depressurizing element for decreasing pressure in the cuff. The pressurizing element is configured to be non-responsive if the patient hazard signal is produced.
