Manufacture of disposable tourniquet cuffs for various non-cylindrical limb shapes
First Claim
1. A method of manufacturing a disposable tourniquet cuff for various non-cylindrical limb shapes, comprising the steps of:
- joining an inner sheet and an outer sheet to form a generally arcuate shaped, inflatable cuff, the cuff having opposing ends and substantially arcuate distal and proximal side edges extending between the opposing ends, the outer sheet extending from one opposing end of the cuff to the other opposing end and consisting of material having an outer fastening surface formed entirely of a first fastener component;
forming an elongated, curvable securing strap that can curve around and conform to the shape of a limb to which the cuff is applied, the strap including a first segment and a second segment, the first segment of the strap including a second fastener component that can releasably engage the outer fastening surface,attaching an outermost end of the securing strap to the outer fastening surface of the outer sheet near a first end of the cuff; and
configuring the second segment of the strap to be different from the first segment of the strap so that the second segment is between the first end of the cuff and the first segment of the strap and so that the second segment of the strap twists to facilitate non-twisting movement of the first segment of the strap toward and away from the substantially arcuate distal and proximal side edges, thereby to enable engagement of the second fastener component on the strap with the outer fastening surface between the arcuate distal and proximal side edges of the cuff.

Abstract
A low-cost contour cuff for surgical tourniquet systems comprises: a sheath containing an inflatable bladder, the sheath having an arcuate shape, an outer surface and a centerline equidistant between first and second side edges; a securing strap non-releasably attached to the outer surface and formed of substantially inextensible material having a shape that is predetermined and substantially flat, wherein the strap includes a bending portion near a first strap end and a fastening portion near a second strap end, and wherein the bending portion is adapted to allow twisting of the bending portion out of the substantially flat shape to facilitate positioning of the fastening portion into any of a plurality of positions in the substantially flat shape; and fastening means for releasably attaching the fastening portion of the securing strap to the outer surface whenever the sheath is curved into a position for surrounding a limb.

16. A method of manufacturing disposable tourniquet cuff for various non-cylindrical limb shapes, comprising the steps of:
-
joining an inner sheet and an outer sheet to form a generally arcuate shaped, inflatable cuff, the outer sheet comprising an outer fastening surface formed of a first fastener component, the cuff having opposing ends and substantially arcuate distal and proximal side edges extending between the opposing ends; forming an elongated, securing strap to include a first segment and a second segment, the first segment of the strap including a second fastener component that can releasably engage the first fastener component, attaching an outermost end of the second segment of the securing strap near a first end of the cuff; and configuring the second segment of the strap to be different from the first segment of the strap and so that the second segment is directly connected between the first end of the cuff and the first segment of the strap and so that the second segment of the strap twists to facilitate non-twisting movement of the first segment of the strap toward and away from the substantially arcuate distal and proximal side edges, thereby to enable engagement of the second fastener component on the strap with the outer fastening surface between the arcuate distal and proximal side edges of the cuff; and
so thatwhen twisted, the second segment can also be curved to conform to the curvature of the limb to which the cuff is applied. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
