The device is adapted to receive an end of the strap and to allow the strap end to be pulled through the device against the action of a deformable spring means (22), thereby progressively increasing the pressure applied to the object. The spring means progressively deflects in proportion to that applied pressure. A linking means (24) translates the deflection of the spring means to the movement of a pointer (23) which thus provides an indication of the pressure being applied by the strap against some reference markings on the strap (25).

Abstract: An ultrasonic diagnostic and therapy system is described for stopping the bleeding of severely damaged blood vessels or vessels severed in a limb amputation. A cuff (30) is attached to the stump of the severed limb which contains a diagnostic transducer array (52, 54, 56) and a HIFU transducer (42, 44). The diagnostic transducer surveys the tissue of the severed limb, searching for a Doppler flow signal. When a Doppler flow signal is detected, the range to and coordinates of the sample volume where the flow was detected are determined, as well as the flow velocity. This information is supplied to a HIFU therapy transducer controller, which controls the HIFU transducer to transmit focused ultrasound to the sample volume of the flow locus, the center of the lumen of a blood vessel. The focused ultrasound heats and coagulates blood in the severed vessel to stem the bleeding.
