Hemorrhage Stops Here™

The Abdominal Aortic & Junctional Tourniquet, the AAJT™

The AAJT Stabilizes the Pelvis!

1 May 2014 - The FDA recognized that the "Inguinal Placement provides for pressure over the hips and pelvis allowing for pelvis stabilization in the event that the pelvis is broken." The Instructions for Use included in the packaging has been updated..

The AAJT saves a life in lower junctional hemorrhage!

4 April 2014 - Another life saved! This time it is on a gun shot victim and a left groin application of the Abdominal Aortic and Junctional Tourniquet (AAJT).

Heart rate 150 bpm, no felt pulse and unobtainable blood pressure. The diaphoretic patient was shot three times, twice in the right leg and once in the left leg. Neither of the wounds in the right leg were bleeding. The wounds in the left leg reflected an entry in the high lateral thigh and exit in the proximal inner thigh with a large amount of blood still coming out of the hole in the inner thigh. A CAT tourniquet was placed above the wounds on the proximal left leg and tightened and the blood flow stopped. The patient was quickly given 2 units of emergency release blood and a liter of saline. His systolic blood pressure came up to a detectable 75 mm Hg. And his heart rate began to drop but only to 130 bpm. At this point the wound began bleeding again. There was no room to fit another CAT tourniquet above the first so a junctional tourniquet was used. The patient was now more alert asking to have the CAT removed. The AAJT was placed in the left inguinal region, secured, tightened and inflated. No further bleeding was noted from the wound. The CAT was not removed but was loosened. The patient reported that the AAJT was far more comfortable than the CAT. We arranged transport to a local level one trauma center. Prior to transport he received two additional units of emergency release blood and an additional liter of saline. He was completely alert and oriented, his pulse now down to 108 and his systolic blood pressure up to 112. He arrived at the trauma center without having to have the AAJT adjusted or further inflated. He went to surgery, survived and walked out of the hospital on postoperative day 3.

The AAJT is approved for 4 hours of use!

6 January 2014 - The AAJT is now recommended for up to 4 hours of use on the inguinal and axillary application sites. It is important to note that the approved administration of the device is to leave it in place regardless of application site or time of application until at definitive surgical care.

The AAJT provides for much lower tissue pressures!

According to Dr. Johnson's work at Wake Forrest, the SAM Junctional Tourniquet required tissue pressures of greater than 700 mm Hg to occlude blood flow in the axillary artery. Dr. Gordon's research at Georgia Health Sciences University showed the AAJT accomplished the same occlusion with only 168 mm Hg of tissue pressure. This was shown in the inguinal region to be the case when the AAJT was compared against mechanical devices like the CRoC and JETT. The AAJT required only 148.5 mm Hg to work effectively but the ISR found the CRoC to require over 800 mm Hg pressure to work. In 2013 the ISR presented data suggesting that these high tissues pressures produced by devices like the CRoC and JETT to cause muscle necrosis and nerve damage.

FDA Clears new 510(k)! The AAT is now the AAJT the Abdominal Aortic & Junctional Tourniquet.

10 December 2013 - The FDA cleared a new 510(k) for the only Class II junctional device the Abdominal Aortic and Junctional Tourniquet! With this clearance new indications and placements are defined for the AAJT.
  • The AAJT becomes the only device with an indication for Pelvic Hemorrhage
  • The AAJT is indicated for groin and axilla placement for 4 hours
  • There is no longer a contraindication for penetrating abdominal trauma
  • There is no longer a hard time for placement in any indicated site. It can and should remain until a physician directs it to be removed.

The AAJT is still the ONLY junctional device to save human life with both upper and lower Junctional hemorrhage.

The AAJT is still the ONLY junctional device to have human research showing safety and efficacy.

On November 3rd the Human study conducted in the UK was published in the journal of Military Medicine http://www.ingentaconnect.com/content/amsus/zmm/2013/00000178/00000011/art00017 We would like to congratulate Major Taylor and Colonel Parker on their very thorough work.

The Abstract reads: "Despite improved body armor, hemorrhage remains the leading cause of preventable death on the battlefield. Trauma to the junctional areas such as pelvis, groin, and axilla can be life threatening and difficult to manage. The Abdominal Aortic Tourniquet (AAT) is a prehospital device capable of preventing pelvic and proximal lower limb hemorrhage by means of external aortic compression. The aim of the study was to evaluate the efficacy of the AAT. Serving soldiers under 25 years old were recruited. Basic demographic data, height, weight, blood pressure, and abdominal girth were recorded. Doppler ultrasound was used to identify blood flow in the common femoral artery (CFA). The AAT was applied while the CFA flow was continuously monitored. The balloon was inflated until flow in the CFA ceased or the maximum pressure of the device was reached. A total of 16 soldiers were recruited. All participants tolerated the device. No complications were reported. Blood flow in the CFA was eliminated in 15 out of 16 participants. The one unsuccessful subject was above average height, weight, body mass index, and abdominal girth. This study shows the AAT to be effective in the control of blood flow in the pelvis and proximal lower limb and potentially lifesaving."

The AAT is now available on GSA Schedule 84 through Speer Operational Technologies

In late April 2013 the AAT saves a life in Afghanistan. The full case report is published in the Summer 2013 edition of the Journal of Special Operations Medicine. The detail provided in the case report provides a picture of the dramatic effect the Abdominal Aortic Tourniquet makes on core physiology. Unlike other junctional devices on the market, that focus on point compression in the groin, the Abdominal Aortic Tourniquet (AAT) is the ONLY device with an approved application site that stops blood flow in the aorta. The casualty not only stopped hemorrhaging but the AAT provided for improved ventilation and lung function.

On June 7th the AAT saves a life in Birmingham, AL! The full case report was published in the JSOM Fall 2013 edition. This is the first case report of a junctional device saving a life in upper junctional hemorrhage. The patient had lost 6 cm of his proximal brachial artery. The upper torso application utilizes the pneumatic displacement directed toward the sternoclavicular joint to stop blood flow in the proximal subclavian artery.

"Hemorrhage Stops Here™"

Compression Works LLC is the only manufacturer of the Abdominal Aortic Tourniquet. This innovative device stops blood flow below the bifurcation of the aorta by applying pressure in the mid to lower abdomen effectively cross-clamping the aorta externally. For difficult to stop inguinal bleeding there is no other product than can effectively stop the blood flow and remain stable and in place during the transport of the patient. Hemorrhage Stops Here™

Don't allow critical red blood cells to be lost. Turn the faucet off and utilize the abdominal aortic tourniquet as quickly as possible. "Time Bleeding is Time Dying™"
