Frequently Asked Questions

MATCombat Tourniquet

Can MATCombat be applied to all extremities?

Yes. The open C-Cuff design of MATCombat provides easy application to both arm and legs. Its construction also enables MATCombat to be easily applied to trapped limbs.

Can MATCombat be applied with one hand?

Yes. The C-Cuff, secure Buckle, and Turn Key together provide fast, one-handed application. MATCombat uses the Mechanical Advantage mechanism to ensure the tourniquet does not slip or loosen.

How fast can MATCombat be applied and tightened to stop blood flow?

Testing has consistently produced complete application and occlusion of blood flow in under 30 seconds1.

How effective is MATCombat at reducing blood loss?

When applied properly, MATCombat is 100% effective at reducing blood loss. In a study conducted at the Kings County Hospital comparing three one-handed tourniquets, MAT® demonstrated 100% occlusion success1. Occlusion in these tests was measured with Doppler, BP and Oximeter sensors.

How durable is MATCombat?

MATCombat has been designed and developed with the highest grade materials, components and manufacturing quality, to military-specifications, including integrated mechanism fail-safe redundancies. MAT® has passed rigorous, independent laboratory extreme conditions and performance tests. It has been designed for a 10 year shelf-life.

Can MATCombat be easily packed and carried?

Yes. MATCombat weighs less than 6 ounces packaged, and comes in a compact package, making it easy to pack into first aid, medical, and military kit bags.

When to Use MATCombat

When Should MATCombat be used?

MATCombat™ can be used to stop moderate to severe extremity blood loss from any limb, including a trapped limb, as a result of trauma to the limb. The C-Cuff, Buckle and Turn Key make one-handed application simple, even while wearing gloves, in extreme environments or while applying MATCombat to oneself.

Who should use MATCombat?

MATCombat has been designed for use by all levels of medical personnel and can be easily and quickly taught to non-medical personnel. It can be used in any environment, including the battlefield, tactical EMS, natural and man-made disasters and hospitals.

Can MATCombat be used on children?

The only restriction on use is the diameter of the affected limb. MATCombat offers an adjustable fit from 4” diameter to 39” circumference.

Using MATCombat

What size limb does MATCombat accommodate?

MATCombat can be used on a wide range of limb sizes — from as small as a 4” diameter forearm to a 39” circumference thigh.

Can the compression of MATCombat be modulated?

Yes. The turn key system provides for easy and safe tightening of the tourniquet in small, controlled increments, making it adjustable for various body types and sizes. To loosen the device, press the Release Button. Then re-cinch the strap, if necessary, and re-engage the Turn Key to re-tighten.

How is blood flow modulated with MATCombat?

Blood flow is modulated by tightening and loosening the Strap by means of the Buckle, Turn Key and Release Button. This may be done in small increments, allowing the user or caregiver ultimate control over the tourniquet’s tightness. To stop moderate to severe extremity blood loss, tighten the strap then rotate and tighten the Turn Key until bleeding stops.

Can MATCombat be released and reapplied?

Yes. There are easy and fast ways to release MATCombat

  1. Push the pressure gate on the buckle to allow the strap to slowly slide through the buckle gate.
  2. Simply press the Release Button on the side of MATCombat to automatically release (usually accompanied by immediate unwinding of the Turn Key mechanism).
  3. The Buckle can be lifted up and off of its hook.

To re-apply and reuse the MATCombat the device must be fully reset. This is done by pushing the Release Button and pulling the Strap all the way out, until you see the stitching at the end of the Strap.

MATCombat and Safety

Can MATCombat be used for multiple applications?

No. To prevent cross contamination, once the device has been used on an injured person, it should be disposed of in the appropriate manner.

For training purposes, MATCombat can be used multiple times, as long as it is properly reset (see previous answer). However, there is a risk that the Turn Key mechanism may bind or fail to work properly after numerous uses if the device is not reset properly.
