Abstract
Abstract An inflatable tourniquet including an elongated flexible tube which encircles a limb of a patient and which has an inlet opening therein for the introduction of fluid into the tube to cause its inflation. The inlet opening in the tube is defined by a fitting which protrudes radially outwardly from the limbencircling tube. A flexible retaining strap having a plurality of longitudinally spaced holes therethrough is provided. The strap extends around the limb, overlapping the limb-encircling tube, and is secured about the tube by having the fitting projecting through selected holes in the strap so that upon inflation of the tube the strap will remain securely wrapped about the limb.

Claim 1
Independent Claim
235 words
In a tourniquet comprising an elongated flattened flexible tube having first and second opposed side walls each defined by longitudinal side and transverse end margins, said side walls being joined at the side and end margins thereof to define an inflatable fluid-retaining envelope between the side walls, said tube being of sufficient length to encircle a limb of a patient with said second tube side wall being adapted to be positioned against said limb, a fitting means carried by said first tube side wall between its side margins and projecting outwardly from the first side wall, said fitting means defining an inlet opening in said envelope for the introduction of fluid into the envelope to inflate the same, a flexible retaining strap having a plurality of spaced holes therein, said holes extending longitudinally along said strap, said strap overlying said second tube side wall with said fitting means projecting through a first of said holes in said strap, said strap including a section having a plurality of said holes therein, said strap section extending longitudinally from one end of said tube and overlapping said strap at said one hole with said fitting means interlockingly projecting through a second of said holes in said strap section, said strap being of sufficient length between Said first and second strap holes to extend around said limb and overlap said tube when said tube is encircled about the limb.
Claim 2
Dependent Claim
