Abstract: This invention relates to a compressive hemostatic belt wherein a cup-shaped rigid case is attached by an attaching device to a predetermined position on a band made of non-stretchable or low-stretchable fiber, nonwoven fabric or film, and a balloon adapted to be inflated by being filled with fluid is received in the rigid case. Preferably, at least the portion of the band which corresponds to the leg when the band is wrapped around the body is shaped in curve form. Buckles may be attached to the opposite ends of the band and a buckle attaching plate may be attached to the rigid case. One end of the band may be provided with projections so that when the band is wrapped around the body, the other end of the band is thrusted on the projections to fix the band in position. If the band is made of adhesive material, more reliable fixing can be achieved. A check valve adapted to prevent fluid from flowing back from the balloon may be removably connected to the balloon to provide for reuse of the check valve.
Abstract: A friction fit fastening device in which a stretchable elongated strap applies radial tension to a body limb or the like to restrict blood flow or to secure objects to the body. The strap can be pulled taut to a desired tension and than held with a fastener when the strap is returned to its natural state. The strap is prevented from slipping because of friction applied to the strap by the fastener. The strap can be easily adjusted or removed by pulling on the strap which decreases the friction applied to the strap by the fastener.
Abstract: A portable apparatus for the treatment of injuries includes a first layer of flexible material and a second layer of flexible material coupled to the first layer of flexible material to form an inflation chamber. A third layer of flexible material is coupled to the first and second layers so that a space is formed between the second and third layers. The space formed between the second and third layers is in fluid communication with the inflation chamber at an outlet and the space between the second and third layers is formed so that a fluid channel extends from a first end of the space between the second and third layers to the outlet. A plurality of spacer members maintain the separation between the second and third layers so that the fluid channel remains unobstructed even when the apparatus is folded or wrapped around an injured area.

The slots are diametrically opposite each other, dividing the tubular body into two sides (32) (34). One side (32) is made shorter than the opposite side (34 ), so as to facilitate the locking action. The device is applied by placing the noose around an object.
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.

Parallel edges of the softer strip extend over and beyond edges of the stiffer strip and are positioned adjacent the body to cushion and protect the body from the stiff strip in use.
Abstract: An improved femoral arterial or venous compressive device includes a flexible pelvic apron positioned over the femoral vessels within the human pelvis. The pelvic apron is placed in position by means of a hip strap. The hip straps are led from the pelvic apron upwardly over the hip points, around the small of the back and down over the opposing hip point back to the pelvic apron. The pelvic apron thus hangs from the hip points of the pelvis much like an apron. A shaped mass or pellet is attached to the under side of the pelvic apron over the incision site of the femoral vessel. An elastically extensible groin strap is then attached to the pelvic apron in the proximity of the shaped mass and drawn tighly through the groin, around the back of the leg, under the buttocks and back upwardly to the pelvic apron in the proximity of the shaped mass. As a result, the tensile force is applied by the groin strap across the pelvic apron up to the hip point and also around the leg.
