ABSTRACT:
An improved method and apparatus (10) for applying a circumferential pressure to an extremity to control blood flow to a distal portion of the extremity. One embodiment (10) of the apparatus of the present invention includes an inflation device (12), an inflatable cuff (14) and a tube (16) interconnecting the inflation device (12) and the inflatable cuff (14). The inflation device (12) preferably includes a syringe pump (18) and a spring unit (20). The spring unit (20) includes a compression spring (36) which resiliently applies a force to the plunger (24) of the syringe pump (18), thereby applying a continuous pressure to the fluid within the syringe cylinder (22). The cuff (14) is thereby supplied with a controlled pressure to control the blood flow through the encircled portion of the extremity.
