Product Overview
The TX3 3" Ratchet Tourniquet by RevMedX occupies a unique position in the CoTCCC-recommended tourniquet landscape: at 3" band width, it is the widest non-pneumatic tourniquet on the CoTCCC-recommended list. The TX Series was added to CoTCCC recommendations in 2019, with both the TX2 (2") and TX3 (3") recognized for their potential to reduce tissue and nerve injury during prolonged field care — a growing operational consideration as combat casualty evacuation timelines extend and Prolonged Field Care (PFC) doctrine matures. RevMedX specifically designed the TX3 for scenarios where conventional 1.5" windlass tourniquets may cause disproportionate localized ischemic injury: large-thigh applications, pediatric patients with fragile tissue, and extended tourniquet times.
The TX3's self-locking polymer ratchet eliminates the windlass rod as a mechanical failure point. The high-density polymer ladder maintains function in the presence of sand and dirt — a critical design requirement validated through military field testing — and does not degrade with repeated use, meaning a single TX3 can serve as both a training and operational device without purchasing separate training-only units. The 60" strap length accommodates a wider range of patient sizes and positioning scenarios than shorter-strap alternatives, while the Bite Strap loop provides a reliable anchor point for true one-handed self-application, particularly for lower-extremity wounds where the injured hand cannot assist. The TX3 has no printed expiration date, reducing the administrative burden of scheduled tourniquet replacement cycles.
For situations where the TX3's larger footprint is a concern, the CoTCCC-recommended C-A-T® Gen 7 (1.5" windlass) and SAM XT (1.5" windlass) offer more compact alternatives. For ratchet-based options with a lighter footprint, see the M2 RMT 2" Wide. Browse the full tourniquets & pouches collection at MED-TAC International.
How to Apply
- Thread or wrap the TX3 around the limb 2–3 inches above the wound. For one-handed application, use the Bite Strap loop to anchor the free end while routing with the functional hand.
- Route the 3" webbing through the ratcheting buckle and pull to start engaging the ladder teeth.
- Continue pulling until bleeding stops and distal pulse is absent — the self-locking ratchet holds each increment of pressure without additional action.
- To fine-tune pressure after initial placement, use the ratchet for incremental tightening; for release, use the mechanical release lever.
- Record application time immediately; communicate to all subsequent caregivers.
Comparison Context
The TX3 is unique among CoTCCC-recommended devices in offering ratchet-based micro-adjustability at the widest available non-pneumatic band width. The C-A-T® Gen 7 and SOF-T® provide more compact packaging and longer track records in peer-reviewed literature. The TX3's standout advantages are its 3" band for prolonged field care applications, no expiration date, dual-use training/operational capability, and function in contaminated environments (sand/dirt) where ladder-strap ratchets outperform velcro or hook-and-loop retention systems.
