Abstract:
1. A method of using a tourniquet comprising: a) attaching a tourniquet around a limb so as to block blood flow therein, said tourniquet comprising: a) a pressure applicator adapted to be mounted on a limb so as to block arterial flow therein, wherein said pressure applicator is a mechanically activated trigger (MAT) comprising a tensile force sensitive element and a switch, wherein said switch is opened or closed based on said tensile force sensitive element, and a transmitter which transmits a signal responsive to activation of said pressure applicator in response to closure of said switch; and b) a timer configured to generate two warnings at two different times, including before a tourniquet danger time is reached, wherein said timer is initiated by said signal transmitted by said transmitter in response to closure of said switch; b) at least determining a start time for said attaching according to transmission of said signal from said transmitter; c) automatically generating a first warning before a danger time is reached as calculated by said timer; and d) automatically generating a second warning when a danger time is reached as calculated by said timer, based on said start time.
