Abstract

Limb protection sleeve matches a specific tourniquet cuff for application to limbs having circumferences between minimum and a maximum circumference so that the sleeve, after application to a limb of minimum circumference, stretches elastically and so that the sleeve, after application to a limb of maximum circumference, applies a pressure to the limb that is less than a predetermined maximum pressure.

Claims

1. Apparatus for protecting a patient'"'"'s limb from tourniquet-related injury, comprising:

a tourniquet cuff having a length sufficient for encircling a limb having a limb circumference within a range of not less than a predetermined minimum and not more than a predetermined maximum, and wherein the cuff has a first indicium thereon that is indicative of that range, and wherein the cuff forms a generally cylindrical shape when encircling the limb and includes a protruding port portion;

a stretchable limb protection sleeve having a tubular shape and an unstretched circumference that is less than the predetermined minimum, the sleeve including a proximal edge and a distal edge, the proximal edge being shaped to have a protrusion such that the width of the sleeve varies between the proximal edge and the distal edge, and wherein the protrusion of the sleeve is underlies the port portion when the sleeve is applied to the limb beneath the cuff; and

matching means carried on the sleeve and perceptible to a user for matching the sleeve to the first indicium of the cuff.

2. The apparatus of claim 1 wherein the matching means includes a second indicium on the sleeve that corresponds to the first indicium on the cuff.

3. The apparatus of claim 2 wherein the sleeve is comprised of two layers, with one layer folded over another layer at a fold edge and so that the edges of the layers away from the fold edge are sewn together at a sewn edge of the sleeve.

4. The apparatus of claim 3 wherein the second indicium is incorporated into the sewn edge of the sleeve.

5. The apparatus of claim 1 wherein the cuff has a predetermined width and forms a generally cylindrical shape when encircling the limb, and whereby the sleeve is sized to be substantially wider than the cuff thereby to enable part of the sleeve to underlie the cuff around the limb while another part of the sleeve is folded over the cuff when the cuff encircles the limb.

6. The apparatus of claim 1 further comprising an instrument attached to the cuff for pressurizing the cuff.

7. The apparatus of claim 2 wherein the first indicium and the second indicium are the same color.
