摘要： An adaptive tourniquet cuff system comprises: a tourniquet cuff (50, 51) having a physical characteristic and including an inflatable bladder of a length greater than the circumference of a limb at a selected location; a cuff connector (20) carried on the cuff and communicating pneumatically with the bladder for releasably connecting to a tourniquet instrument (12) to establish a gas-tight passageway between the bladder and the tourniquet instrument; and an identifying collar including identification means indicative of the physical characteristic and detectable by the tourniquet instrument upon establishment of the gas-tight passageway. The tourniquet instrument may supply gas to the bladder through the gas-tight passageway at a pressure sufficient to stop arterial blood flow into the limb distal to the cuff at the selected location, and may adapt its operation in response to the detected physical characteristic of the cuff.

摘要： 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.

摘要： Disclosed is a system and method for regulating tourniquet cuff pressure to restrict blood flow penetration past the cuff based on a personalized restrictive pressure (PRP). The system includes mechanisms for estimating a limb occlusion pressure (LOP) by determining a minimum pressure at which arterial blood penetration past an applied tourniquet cuff is stopped and measuring a pulsation characteristic associated with the LOP. Thereafter, the system establishes a PRP by determining a second pressure that restricts but does not stop arterial blood penetration past the cuff and that corresponds to a second pulsation characteristic differing by a percentage from the pulsation characteristic associated with the LOP. During a limb-activity time period, the system maintains pressure in the applied tourniquet cuff near the PRP, thereby restricting but not stopping arterial blood penetration past the cuff during the activity time period.

摘要： A surgical tourniquet cuff that includes a stabilizer component that facilitates application of an overlapping cuff around the limb of a patient. The stabilizer is fixed to the cuff, and requires no tying or similar user manipulation to secure the overlapping cuff in alignment with the underlying cuff. The stabilizer improves the stability of the inflated cuff to prevent sideways shifting motion of overlapping cuff portions as the cuff is applied to the limb. The stabilizer also provides a handle mechanism to enable the user to snugly apply the overlapping cuff around the patient's limb while the overlapping portions remain properly aligned along their long axes. The stabilizer is designed to also facilitate attaching together two tourniquet cuffs end-to-end, with respective bladders overlapping and in proper alignment so that those attached cuffs can be used as a single, extended surgical cuff applied around a patient's limb.
