Abstract: A tourniquet cuff has minimal flow restrictions within its pneumatic passageway under normal operating conditions, has a substantially reduced likelihood of partial or complete obstructions or interruptions of the pneumatic passageway under foreseeable operating conditions, can indicate exposure of the cuff to external agents that are capable of affecting the integrity of the pneumatic passageway before use, and can be manufactured economically.

Abstract: Disclosed are methods of manufacturing and inflating an elongated bladder of a tourniquet cuff that may be secured around the limb of a patient. The method includes sealing together side edges of layers of material to form the bladder, and stiffening the cuff with a stiffener for compressing the portion of the bladder underlying the stiffener inwardly toward the limb while preventing two layers of the cuff from contacting each other at a location adjacent to an edge of the cuff to thus provide a continuous pneumatic passageway in the bladder between the overlying stiffener and the sealed edge for distributing inflating gas through the passageway along the length of the bladder.

Abstract: An adaptive tourniquet cuff system comprises: a tourniquet cuff 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 carried on the cuff and communicating pneumatically with the bladder for releasably connecting to a tourniquet instrument 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.
