Easy-to-use tourniquet with elastic sleeve – MA00386

Market challenges

Historically, major blood loss resulting from severe wounds has been shown to be the major leading cause of death on the battlefield and directly correlates to major trauma in the civilian sector.

Thus, the use of tourniquets to manage life-threatening hemorrhaging in extremities has been essential, because of the immediate lifesaving intervention capability and the speed with which they can be applied.

However, they have certain limitations of use: known tourniquet devices tend to be structurally complicated, making it difficult for the victim to single-handle and address his own hemorrhaging condition. As for the inflatable tourniquets, they are sensitive to altitude variations.

Innovative solution

The solution is a tourniquet, pre-positioned around a limb (on the clothes), that can be triggered directly by the victim, using only one-hand. It is composed of:

• A support, pre-positioned on the clothes, surrounding a limb
• An elastic sleeve held in a stretched position around the support (which prevents it from retracting)

When the system is triggered (by simply pulling a gripping element from the support, which can be done manually by the victim, using only one-hand), the elastic sleeve is displaced (out of the support), causing it to retract around the limb, compress it and block blood flow.

A pin prevents an accidental setting off of the tourniquet.

Suggested applications

This tourniquet was designed to be pre-positioned on the clothes, before an injury. The main target markets are:

• The military and para-military
• Police and other security forces
• Other applications might be possible (risky recreational outdoor activities etc.)

Development status

A functional prototype has been developed.

Competitive advantages

• Removable, easy to handle and trigger
• Structured to be used single-handedly
• Insensitive to altitude variations
• A guaranteed minimal standardized compression, regardless of the user
• Developed with the French Defense Health Service
• A patent application has been filed in February 2017
