Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 16/380,935, filed Apr. 10, 2019, which claims the benefit of U.S. Provisional Application No. 62/655,574, filed Apr. 10, 2018, which are hereby incorporated by reference in their entirety.

BACKGROUND

Hemorrhage is the leading cause of combat deaths. In many cases, applying a tourniquet after sustaining a wound in an appendage is too painful to apply effectively. In some cases, a person, such as an injured soldier, law enforcement officer, or government agent loses consciousness and is unable to apply self-aid. Self-aid on multiple extremities is unlikely in most battleground cases since each solder is typically issued one tourniquet. In many cases, medical personnel cannot reach a wounded soldier, law enforcement officer, or government agent in time to locate a tourniquet, place the tourniquet in position, secure the tourniquet on a limb, tighten the tourniquet, and (optionally) lock the tourniquet in a tightened position to cease a hemorrhage.
Many existing tourniquets may not be considered as effective devices to occlude blood flow to prevent spread of venom throughout the body. This is due to the amount of time it typically takes to don and effectively activate many of the existing tourniquets. Venom may be secreted by invertebrates, fish, amphibians, and reptiles. Examples of animals that may secrete venom include stonefish, stingrays, jellyfish, bees, wasps, spiders, komodo dragons, snakes, and scorpions.
Many existing tourniquets may have excess weight and/or bulk. Excess weight and/or bulk may reduce the number of tourniquets carried by a user or a first responder.
Many existing tourniquets may be difficult to place on a limb for effective occlusion. Many existing tourniquets may be difficult to operate. Many existing tourniquets may not be adaptable to a variety of limb sizes and limb types (e.g. legs, arms). Operation by a person who has not been trained in proper tourniquet placement and operation is often too difficult to complete effectively. In some cases, a person may be in too much pain to effectively apply self-aid to occlude blood flow. Operation by medical personnel may take too much time in cases involving mass injuries such as, for example, on a battlefield, in a terrorist attack, in a natural disaster, or after a multivehicle accident.
Many existing tourniquets may not provide the durability and/or the wearability necessary for effective combat and/or immediate use. Many existing tourniquets may be difficult to operate while wearing gloves. Many existing tourniquets may not apply enough pressure to completely occlude blood flow in an artery of a wearer. Many existing tourniquets may rely on a pressure ridge that needs to be located directly over an artery to occlude blood flow. Many existing tourniquets may cause scrunching of tourniquet material during use which may cause unnecessary discomfort to the user and/or may prevent effective occlusion. Many existing tourniquets may locate an adjustment mechanism on a medial side of a limb. In this location, the adjustment mechanism may be engaged or disengaged prematurely.
