Tourniquet cuff with improved pneumatic passageway

摘要

A tourniquet cuff (10) has minimal flow restrictions within its pneumatic passageway (54) under normal operating conditions, has a substantially reduced likelihood of partial or complete obstructions or interruptions of the pneumatic passageway (54) under foreseeable operating conditions, can indicate exposure of the cuff (10) to external agents that are capable of affecting the integrity of the pneumatic passageway (54) before use, and can be manufactured economically.
