Abdominal Aortic & Junctional Tourniquet - AAJT™
Item code: 30401
The AAJT™ (Abdominal Aortic & Junctional Tourniquet) is a circumferential device that utilizes a belt, windlass, and pneumatic pressure to compress the aorta or the arteries supplying the groin or axilla. The belt and the windlass together greatly increase the stability of the compression. The pneumatic, wedge-shaped bladder provides focused pressure to safely squeeze the blood vessels to prevent flow.
Why Is The AAJT Needed:
Blood is the vital component to surviving blunt or penetrating trauma. Because blood allows oxygen to be carried to the heart, brain, and kidneys, every drop lost, impacts survival. Junctional hemorrhage, bleeding from the areas at the junction of the trunk and its appendages, is a difficult problem in trauma. These areas are not amenable to regular tourniquets, as they cannot fit well enough to provide circumferential pressure to the junctional regions of the body. Thus, junctional injuries can rapidly lead to death by exsanguination. Out-of-hospital control of junctional bleeding can be lifesaving. In fact, research demonstrates the safety and the effectiveness in non-invasively cross-clamping the aorta or fully stopping all blood flow to the pelvis and the lower extremities. This can be accomplished by using the AAJT.
How Does The AAJT Work:
The target of the compression for pelvic-junctional hemorrhage is the aortic bifurcation, which has historically been identified in relation to the umbilicus or the superior margin of the iliac crests. Compression at this level is effective and safe and approved by the FDA. If only one leg or groin is injured, the device is placed over the effected side and inflated. The lower tissue pressures over the groin make it the most comfortable junctional device to be applied in this region. The target of compression for upper junctional bleeding is the axilla with the compression stopping blood flow in the proximal subclavian artery.
When applied to the groin, the AAJT is effective using less pressure than that required for the Combat Ready Clamp (CRoC), Junctional Emergency Treatment Tool (JETT) or SAM Junctional Tourniquet to work. The large bladder of the AAJT applies pressure over an increased surface area, allowing for lower overall tissue pressures. This allows for a reduced risk of tissue and nerve injury than other junctional devices. In essence, the AAJT acts as a valve to figuratively turn the faucet off and to prevent the further flow of blood out of wounds below its application site.
Where Can The AAJT Be Applied :
UPPER & LOWER:
- The AAJT is the ONLY junctional tourniquet to have saved human life in upper and lower junctional hemorrhage.
JUNCTIONAL HEMORRHAGE SITES:
- It is FDA cleared for all junctional hemorrhage sites (axilla and inguinal placements) and can remain on for up to "four hours" in these locations.
- The AAJT can be applied to the mid-abdomen, tightened, and inflated to control bleeding in the pelvis, groin and legs.
The Advantages Of The AAJT:
- The AAJT is the ONLY device to have an approved indication for bleeding in the pelvis, which is a common complication in lower junctional trauma;
- The AAJT is the ONLY device to save human life upper & lower junctional bleeding;
- The AAJT is the ONLY device with human research that supports its safety and efficacy;
- The AAJT is the most stable junctional device during patient movement;
- The AAJT provides the capability to be used as a triage and assessment tool, with a blood-free field to identify wounds and apply appropriate interventions;
- The AAJT can be applied to one inguinal region for one-sided inguinal or leg injuries.
- The AAJT has no effect on diaphragm movement during application;
- The AAJT is one device for all junctional bleeding;
- The AAJT is the ONLY device with independent international validation of its effectiveness;
- The AAJT can be applied in "Less Than 45 Seconds";
- The AAJT is simple enough to be applied by non-medical providers, since its application doesn't require knowledge of the vascular anatomy;
- The AAJT provides definitive cessation of arterial blood flow below the umbilicus, at the groin, or in the axilla by stopping proximal arterial flow.
- The AAJT has demonstrated the ability to stay in place and maintain efficacy during patient movement in confined space rescue, drags, and hasty extraction.
- The AAJT enables lower tissue pressures for increased comfort and decreased risk of secondary tissue and nerve injury;
- The AAJT has a larger volume and more physiologically focused bladder design than any other pneumatic device.
