Abstract

A disposable plastic tourniquet which includes an inflatable elongated envelope formed from three layers of vinyl plastic, of which one layer extends from one end of the envelope to form a long tongue. A sheet of stiffening material is positioned between two of the layers of vinyl to increase the contact surface, and a strip of pressure sensitive tape extends from each side of the envelope to engage the tongue and lock the tourniquet in possition on the patient.

Claims

1. A disposable inflatable tourniquet including in combination an elongated inflatable envelope member for wrapping around a body member, a tongue member extending from one end of the envelope to be wrapped over at least a portion of the envelope, stiffening means carried by said envelope for increasing the contact surface of the envelope with the body member when inflated, and adhesive strip means on said envelope for cooperating with said tongue for holding the tourniquet in position about the body member, said adhesive strip means including a length of adhesive tape extending from one side of said envelope for placement over said tongue member to hold said tongue member against said envelope, and a second length of adhesive tape extending from the other side of said envelope, said tongue member being of sufficient length to extend past said first length of tape and be doubled back upon itself, and said second length of tape being for placement over the doubled back portion of said tongue member to lock said tongue member against slipping.

2. A tourniquet according to claim 1 wherein said first and second lengths of tape are longer than said tongue member is wide so that the free ends of said lengths of tape engage said envelope member.

3. A tourniquet according to claim 2 wherein said lengths of tape are provided with a pressure sensitive adhesive.

4. A tourniquet according to claim 1 wherein said envelope is formed from an upper layer of plastic material, an intermediate layer of plastic material, and a lower body contacting layer of plastic material, and wherein said stiffening means is positioned between said upper and said intermediate layers of plastic material, said upper and said intermediate and said lower layers of plastic material being sealed together around the edges thereof, said intermediate and said lower layers of plastic material providing an inflatable chamber.

5. A tourniquet according to claim 4 wherein said intermediate and lower layers of plastic material are of substantially equal length and said upper layer extends past one end of the other layers of plastic material to provide said tongue member.

6. A tourniquet according to claim 5 wherein said upper and intermediate layers of plastic material are provided with aligned openings, a fitting is attached to said envelope member in alignment with said openings, and said upper and intermediate layers of plastic material are sealed together around said openings.
