Abstract

The present invention relates generally to first aid articles and more specifically tourniquets. One embodiment of the claimed subject matter includes a tourniquet article comprising a base, a cap disposed on said base, a strap having one free end and one end attached to said base, a buckle attached to said base, a handle with an aperture to accommodate a portion of said strap, a ring attached to said base positioned adjacent to said base, wherein said tourniquet article is positioned around a limb, wherein said free end of said strap is pulled through both said ring and said handle aperture whereby said article is initially tightened around the limb, wherein said handle is turned until adequate pressure is applied to the limb, and wherein once adequate pressure is applied to the limb, one end of said handle is inserted into said ring to secure the tightened tourniquet in place. Another embodiment includes a safety screw disposed in said buckle, wherein said screw is tightened to prevent said strap from slipping. Another embodiment has a ring that is movable along the base. Another embodiment of the tourniquet article further includes a second ring disposed on said base positioned adjacent to said buckle.

Claims

1. A tourniquet article comprising:

A substantially rigid base;

a handle; and

a strap in communication with said handle, the strap being engaged with said base at a first point upstream from said handle and fixedly attached to said base at a second point downstream from said handle such that said handle is maintained in a position relative to said substantially rigid base to reduce binding of said base when said handle is twisted,

wherein said handle is a rod including notches disposed at first and second end portions.

2. The tourniquet article of claim 1 wherein said strap has a width of between about 1 inch and about 2.5 inches and said handle includes an aperture that is slightly wider than said strap.

3. The tourniquet article of claim 2 wherein said strap passes through the aperture.

4. The tourniquet article of claim 1 wherein said base is substantially rigid and comprises a layered composite including a lower layer comprised of one of a non-skid fabric, a non-slip fabric and a hook and loop fastener.

5. The tourniquet article of claim 4 wherein the layered composite includes an intermediate layer affixed to said lower layer and an upper layer affixed to said intermediate layer, said upper layer comprising a substantially rigid material.

6. The tourniquet article of claim 5 wherein the upper layer comprises a plastic material.

7. The tourniquet article of claim 5 wherein the upper layer comprises nylon scuba webbing.

8. The tourniquet article of claim 5 wherein the intermediate layer comprises a polypropylene webbing.

9. The tourniquet article of claim 1 further comprising a handle lock attached to said base and positioned to receive an end of said handle.

10. The tourniquet article of claim 9 wherein the handle lock includes a ring movably attached to said base.

11. The tourniquet article of claim 1 further comprising buckle connected to said substantially rigid base, said buckle being adapted to engage said strap to secure said tourniquet in a deployed arrangement, said buckle being tapped to accept a screw to secure said strap to said base.

12. The tourniquet article of claim 1 wherein said handle includes an aperture disposed in the center thereof and said strap is threaded through said aperture.

13. The tourniquet article of claim 1 wherein said base includes means for holding said tourniquet article in place to facilitate user application of said tourniquet article with one hand.

14. A tourniquet article comprising:

an elongated handle;

a substantially rigid base;

a strap disposed contiguous to said base and in communication with said handle; and

a structural member having first and second sides, said structural member being fixedly attached to said base at least at first and second points along each of the first and second sides, said strap being sandwiched between at least portion of said structural member and said base to minimize twisting of said strap.

15. The tourniquet article of claim 14 wherein said structural member includes a cap.

16. The tourniquet article of claim 14 where said strap includes a free end and an end portion attached to said base.

17. The tourniquet article of claim 14 wherein said structural member, said strap and said base form a layered assembly.

18. The tourniquet article of claim 14 wherein said strap is fixedly attached to said base at an attachment point.

19. A tourniquet article comprising:

an elongated handle;

a substantially rigid base underlying said elongated handle;

a strap configured to be tightened about an injured limb, said strap being engaged with said handle and being engaged with said substantially rigid base at i) a first point upstream from said handle and ii) at a second point downstream from said handle such that said substantially rigid base is maintained in underlying relationship to said handle thereby reducing binding of said substantially rigid base when said handle is twisted; and

a buckle connected to and disposed proximate and end portion of said substantially rigid base, said buckle being adapted to engage said strap to secure said tourniquet in a deployed arrangement.

20. The tourniquet article of claim 19 wherein said strap is planar and further comprising means for maintaining said strap flat against said base.
