Abstract
Abstract A tourniquet constructed from a length of elastic material. The ends of the elastic material are made non-elastic, and complementary coupling components are attached thereto. The elastic material is provided with a thickening for stress absorption and control.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
141 words
A tourniquet adapted to encircle a limb with opposite end portions of said tourniquet overlapping one another to form a closed band around said limb comprising a strip of elastic material, said strip including a center section and two end sections, said end sections being reinforced with an inelastic material embedded in said elastic material at said end sections to render said end sections relatively inelastic, said inelastic material having an inboard edge, complementary releaseable coupling means secured to said end sections, the elastic material of said center section and said end sections being thickened at their juncture to provide a section of thickened elastic material extending at least a relatively short distance on either side of the inboard edge of said inelastic material to reduce the likelihood of failure of said elastic material proximate to said center section-end section junctures.
Claim 2
Dependent Claim
141 words
A tourniquet adapted to encircle a limb with opposite end portions of said tourniquet overlapping one another to form a closed band around said limb comprising a strip of elastic material, said strip including a center section and two end sections, said end sections being reinforced with an inelastic material embedded in said elastic material at said end sections to render said end sections relatively inelastic, said inelastic material having an inboard edge, complementary releaseable coupling means secured to said end sections, the elastic material of said center section and said end sections being thickened at their juncture to provide a section of thickened elastic material extending at least a relatively short distance on either side of the inboard edge of said inelastic material to reduce the likelihood of failure of said elastic material proximate to said center section-end section junctures.
Claim 3
Dependent Claim
21 words
The tourniquet of claim 1, wherein the inboard edge of said inelastic material is so constructed and arranged to be fray-free.
Claim 4
Dependent Claim
20 words
The tourniquet of claim 1, wherein said inelastic strips are folded back upon themselves to reinforce the inboard edge thereof.
Claim 5
Dependent Claim
149 words
A tourniquet adapted to encircle a limb with opposite end portions of said tourniquet overlapping one another to form a closed band around said limb comprising a strip of elastic material, said strip including a center section and two end sections, said end sections being reinforced with an inelastic material embedded in said elastic material at said end sections to render said end sections relatively inelastic, complementary releaseable coupling means secured to said end sections, the elastic material of said center section and said end sections being thickened above and below said inelastic material for at least a relatively short distance on either side of the inboard edge of said inelastic material to form a thickened unitary portion of said strip to provide a reservoir of material communicating with said center portion to reduce the likelihood of failure of said elastic material proximate to said center section-end section junctures.
Claim 6
Dependent Claim
149 words
A tourniquet adapted to encircle a limb with opposite end portions of said tourniquet overlapping one another to form a closed band around said limb comprising a strip of elastic material, said strip including a center section and two end sections, said end sections being reinforced with an inelastic material embedded in said elastic material at said end sections to render said end sections relatively inelastic, complementary releaseable coupling means secured to said end sections, the elastic material of said center section and said end sections being thickened above and below said inelastic material for at least a relatively short distance on either side of the inboard edge of said inelastic material to form a thickened unitary portion of said strip to provide a reservoir of material communicating with said center portion to reduce the likelihood of failure of said elastic material proximate to said center section-end section junctures.
