Matching limb protection sleeve for tourniquet cuff
First Claim
1. A method for matching components of an apparatus for protecting a patient'"'"'s limb from tourniquet-related injury, comprising the steps of:
- selecting a tourniquet cuff component having a length sufficient for encircling a limb at a location having a limb circumference of not less than a predetermined minimum limb circumference and not more than a predetermined maximum limb circumference;
providing a limb protection sleeve component that is configured to have a tubular shape and a tubular circumference predetermined to be less than the predetermined minimum limb circumference wherein the sleeve is formed to allow elastic stretching of the tubular shape sufficient to increase the tubular circumference to be substantially equivalent to the limb circumference when the sleeve is applied to the limb between the cuff and limb, thereby applying a pressure to the limb that is greater than a predetermined minimum pressure and less than a predetermined maximum pressure;
establishing the predetermined maximum pressure applied by the sleeve to the limb to be less that a pressure for partially obstructing venous blood flow in the limb by measuring the pressure applied by the sleeve to the limb; and
matching the selected tourniquet cuff component and limb protection sleeve component by marking the cuff and sleeve to indicate that those two components match one another.

Abstract
Apparatus is provided for protecting a patient'"'"'s limb from tourniquet-related injury, comprising: a tourniquet cuff having a length sufficient for encircling a limb protection sleeve applied to a limb at a location having a limb circumference of not less than a predetermined minimum limb circumference and not more than a predetermined maximum limb circumference; limb protection sleeve adapted for applying to the limb at the location, wherein the sleeve has a tubular shape and a tubular circumference predetermined to be less than the predetermined minimum and wherein the sleeve is formed to allow elastic stretching of the tubular shape sufficient to increase the tubular circumference to be substantially equivalent to the limb circumference at the location when the sleeve is applied to the limb, thereby applying a pressure to the limb that is greater than a predetermined minimum pressure and less than a predetermined maximum pressure; and identification means perceptible to a user for providing an indication to the user of the predetermined minimum limb circumference and the predetermined maximum limb circumference.

5. A tourniquet cuff and sleeve system comprising:
-
a tourniquet cuff having a width, a length, and a fastening mechanism, the cuff being flexible for being lapped upon itself into a cylindrical configuration having one of a range of circumferences and within which range the fastening mechanism completely engages to secure the cuff in the cylindrical configuration; a tubular stretchable sleeve of uniform thickness and having an unstretched circumference that is smaller than the range of cuff circumferences, wherein the sleeve is formed to apply a pressure to a limb having a circumference within the range that is greater than a predetermined minimum pressure and less than a predetermined maximum pressure; and
whereinthe sleeve has a width that is greater than the width of the cuff thereby to enable part of the sleeve to completely underlie the cuff when the cuff is in the cylindrical configuration while another part of the sleeve is folded over the cuff; and matching means for providing a visual indication of a size correspondence between the cuff and sleeve. - View Dependent Claims (6)

7. A method for correlating one size of a number of different-sized stretchable sleeves with a particularly sized tourniquet cuff that surrounds a limb of a predetermined circumference, comprising the steps of:
-
selecting a sleeve that has an unstretched circumference that is smaller than the limb circumference and that applies to the limb a pressure that is greater than a first predetermined, pre measured amount of 2 mm Ha and less than a second predetermined, pre-measured amount when the sleeve surrounds the limb; and marking the selected sleeve in a manner to show correlation with the cuff. - View Dependent Claims (8)
