ABSTRACT:
A pneumatic tourniquet includes an inflatable cuff, a pressurizing mechanism for pressurizing the cuff, a pressure relief mechanism for depressurizing the cuff, a pressure sensing mechanism for sensing the pressure to which the cuff is pressurized and a pressure regulator mechanism for selectably activating the pressurizing mechanism and the pressure relief means to maintain the cuff pressure near a selected pressure. Visual and audible alarm signals are triggered if the cuff pressure exceeds a cuff pressurization limit, if the cuff pressure falls below a cuff depressurization limit, or if the cuff has remained pressurized for, or in excess of a selected time period.
A computer may be used to sense the cuff pressure and pressurized or depressurized the cuff as required to maintain the cuff pressure within upper and lower cuff pressure limits.
