Emergency tourniquet cuff-like device

Emergency withers

Emergency tourniquet cuff-like device designed to stop a bleeding disorder before or during transport to a processing facility. They are wrapped around the limb, near the site of trauma and constrict blood vessels in all the congestion. Design and construction of emergency tourniquets allows quick application by the respondent or first aid injury. Use the right equipment has been proven to save lives withers under difficult conditions with a relatively low risk of injury. In field tests, the application prompts you before tourniquet emergency patients in shock associated with a higher survival rate than other scenarios where the turnstiles used later or not at all

Turnstile design

Existing guidelines include the use of makeshift "rope and stick" tourniquet as a last resort to stop severe bleeding. However, the purpose-made tourniquet devices that are well designed to ensure the safety and efficiency greatly improved . Variability in performance was demonstrated between the different models and methods of application.
Mechanical advantage

The mechanism that provides sufficient mechanical advantage is very important to apply sufficient pressure to stop bleeding, especially in the lower extremities. Occlude the venous blood pressure, but the flow can aggravate bleeding and damage to healthy tissue.

Pressure gradient

Under the pressure of the tourniquet cuff is uneven, with the high pressure cap is located around the center and decreases to zero near the edge of the cuff. A high level of pressure variation across a wide sleeve or cuff gradient at high pressure, a major cause of damage to the nerves and muscles of the use of a tourniquet. Turnstiles with wider straps or wrist, particularly those with a force different mechanical pneumatic actuation, distributes pressure more evenly and produces a low pressure gradient. They are more likely to stop the bleeding and less likely to cause damage to the underlying tissues, in addition to being much less painful than the turnstiles with narrow straps and band. Protection against overpressure in some emergency tourniquets also help prevent excessive force to damage the industry.

It is necessary

Despite widespread success tourniquet to limit the spread of war wounded, many preventable deaths bleeding when using traditional tourniquet inappropriate content. It is necessary to control bleeding junction, especially in the pelvic region. In 2012, the Combat Ready Clamp (Croc) selected by the U.S. Army Institute of Surgical Research (USAISR) for this purpose. Another requirement is that the training regime appears smoother and doctrine based on scientific evidence, which can ensure that future policies and practices withers in line with the current body of knowledge.
