Abstract
A tourniquet apparatus having an optical tourniquet interface for safe personalization, a safe transfer key and a pressure controller. The optical tourniquet interface communicates with the pressure controller and is operable for contactlessly reading and authenticating a machine-readable instrument symbol associated with a tourniquet cuff if it matches stored instrument authentication data and for contactlessly reading machine-readable personalization data associated with the cuff. The optical tourniquet interface presents a personalization parameter value if the machine-readable instrument symbol has been authenticated. The safe transfer key enables the user to selectively transfer the presented value of the personalization parameter to the pressure controller only if the pressure controller is inoperable. The pressure controller is releasably connectable to the tourniquet cuff and responsive to the transferred value of the personalization parameter. The pressure controller is operable for automatically controlling a level of pressure in the tourniquet cuff during a pressure control time period.
