Climbing harness with built-in tourniquet
View Patent ↗A system of a combined climbing harness and medical tourniquet, and a method for using the system. A looped thigh strap portion of a climbing harness is detachable from the harness belt for separate alternative use as an emergency tourniquet for the user or a patient. The looped thigh strap is provided with features and components to facilitate its use as a functional tourniquet for either an arm or a leg, while nevertheless in ordinary use allowing it to serve as a component of a climbing harness.
1. A method for applying a tourniquet to an injured limb, comprising:
providing a climbing harness system comprising a main belt and a thigh strap having a body;
disposing on the thigh strap a holder loop and a second loop proximate to the holder loop;
releasably engaging the thigh strap to the main belt;
wrapping the main belt about a user's upper hips;
wrapping the thigh strap around the user's thigh, and releasably engaging the thigh strap to define a closed loop;
engaging the harness system with a rope, and climbing with the rope;
disengaging the thigh strap from the main belt;
looping the thigh strap around the injured limb;
engaging a torsion item with the holder loop by inserting the item between the holder loop and the body of the thigh strap;
rotating the torsion item to twist the holder loop, thereby shortening an effective circumferential length of the closed loop of the thigh strap, and constricting the injured limb;
engaging the torsion item with the second loop to maintain the holder loop in a twisted condition.
2. The method of claim 1 wherein disposing on the thigh strap the holder loop comprises securely attaching to the strap body two ends of a loop strip of flexible fabric.
3. The method of claim 2 wherein securely attaching two ends of the strip comprises:
affixing a reinforcing overlay layer to the strap body;
sewing the two ends of the strip between the strap body and the reinforcing overlay layer; and
defining with the loop strip the holder loop distending a distance from the body.
4. The method of claim 2 further comprising providing the strap body with a bendable stiffener element substantially adjacent the loop strip.
5. The method of claim 1 wherein releasably engaging the thigh strap to the main belt comprises:
providing a center main loop securely attached on the main belt;
defining on the thigh strap a main strap loop; and
disposing a carabiner through the center main loop and through the main strap loop, and closing the carabiner.
6. The method of claim 5 wherein disengaging the thigh strap from the main belt comprises opening the carabiner and detaching it from the center loop and from the main strap loop.
7. The method of claim 6 wherein engaging the torsion item comprises engaging the carabiner.
8. The method of claim 7 wherein rotating the item comprises rotating the carabiner.
9. The method of claim 8 wherein rotating the carabiner comprises rotating the carabiner around an imaginary axis of rotation oriented generally oblique to the strap body.
10. The method of claim 9 wherein engaging the torsion item with the second loop comprises clipping the carabiner to the second loop.
11. The method of claim 1 wherein releasably engaging the thigh strap to define the closed loop comprises:
attaching a buckle at an intermediate location on the thigh strap; and
engaging a first free end of the thigh strap with the buckle.
12. The method of claim 11 , further comprising tightening the closed loop on the injured limb by moving the thigh strap relative to the buckle.
13. The method of claim 11 wherein defining on the thigh strap a main strap loop comprises folding a second end portion of the thigh strap upon itself, and sewing the strap securely to itself.
14. The method of claim 1 wherein engaging the torsion item comprises engaging a carabiner.
15. The method of claim 14 wherein engaging the torsion item with the second loop comprises clipping the carabiner to the second loop.
16. A method for applying a tourniquet to an injured limb, comprising:
providing a climbing harness system comprising a main belt and a thigh strap having a body;
disposing on the thigh strap a holder loop and a second loop proximate to the holder loop;
releasably engaging the thigh strap to the main belt, comprising:
providing a center main loop on the main belt;
defining on the thigh strap a main strap loop; and
disposing a carabiner through the center main loop and through the main strap loop, and closing the carabiner;
wrapping the main belt about a user's upper hips;
wrapping the thigh strap around the user's thigh, and releasably engaging the thigh strap to define a closed loop;
disengaging the thigh strap from the main belt, comprising opening the carabiner and detaching it from the center loop and from the main strap loop;
looping the thigh strap around the injured limb;
engaging the carabiner with the holder loop by inserting the carabiner between the holder loop and the body of the thigh strap;
rotating the carabiner to twist the holder loop, thereby shortening an effective circumferential length of the closed loop of the thigh strap, and constricting the injured limb; and
engaging the carabiner with the second loop to maintain the holder loop in a twisted condition.
17. A method for applying a climbing harness as a tourniquet to an injured limb, comprising:
providing the climbing harness with a main belt and a thigh strap having a body;
securing on the main belt a center loop means through which a carabiner may be removably attached to the main belt;
disposing on the thigh strap a holder loop and a second loop proximate to the holder loop;
wrapping the main belt about a user's upper hips;
releasably engaging together with the carabiner the center loop and the thigh strap;
wrapping the thigh strap around the user's thigh, and releasably engaging the thigh strap to define a closed loop;
engaging the harness system with a rope, and climbing with the rope;
disengaging the thigh strap from the main belt;
looping the thigh strap around the injured limb;
engaging a torsion item with the holder loop by inserting the item between the holder loop and the body of the thigh strap;
rotating the torsion item to twist the holder loop, thereby shortening an effective circumferential length of the closed loop of the thigh strap, and constricting the injured limb;
engaging the torsion item with the second loop to maintain the holder loop in a twisted condition.
18. The method of claim 17 wherein the step of disposing the holder loop comprises securely attaching to the strap body two ends of a strip of flexible fabric.
19. The method of claim 18 wherein:
attaching to the strap body two ends of the strip comprises the step of affixing a reinforcing overlay layer to the strap body; and
sewing the two ends of the strip between the strap body and the reinforcing overlay layer, so that the strip defines the holder loop distending a distance from the strap body.
