ABSTRACT:
A distal forearm tourniquet and method of use therefor for providing a bloodless field during hand surgery is disclosed. The tourniquet includes an adjustable strap or cuff formed with an inflatable balloon on a portion thereof. In use, the tourniquet is placed with the balloon on the dorsal aspect of the forearm between the middle and distal 1/3 and securely tightened to restrict blood flow. In fixed position, the inflatable balloon is located against the dorsal aspect of the forearm and inflated to a desired pressure. The resulting application of the pressure exerted on the dorsal aspect by the balloon and indirect pressure on the volar aspect of the forearm restricts blood flow through the radial and ulnar arteries and the anterior and posterior interosseous arteries. Since the interosseous arteries are nearly hidden between the radius and ulna bones, arterial blood flow therethrough normally cannot be shut off effectively by the application of a conventional pneumatic tourniquet with safe pressure applied around the distal forearm as this exerts circumferential and not bidirectional pressure. The balloon may be provided with an inlet tube containing a one-way check valve preventing expulsion of air from the inflated balloon. A manual sphygmomanometer or compressed air may be used to constantly monitor and regulate inflation pressure.
