PRODUCT INFORMATION

Safeguard Medical · Limb Tourniquet

Tactical Mechanical Tourniquet (TMT™)

A windlass-style limb tourniquet on a 2 in. strap with no internal band. You ratchet the slack out by pulling the tail, twist the torsion bar until the bleeding stops, and it clicks when it locks. A quick-disconnect buckle opens the loop for a trapped limb. Labeled for limbs 5.75 to 38 in. around, 3.5 oz packaged, in black and orange.

evidence-based standard2 in. strap, no internal bandAudible torsion-bar lockLimbs 5.75–38 in.Made in the USA

The TMT asks for one extra habit — ratchet the tail before you twist — and pays it back with a click you can hear when it locks.

The short answer

What it is

A one-handed limb tourniquet: 2 in. strap, quick-disconnect buckle, torsion bar, retaining clip and time label tab.

Use it for

Life-threatening bleeding from an arm or a leg — including a trapped limb — and any traumatic amputation of a limb.

How it's used

Under threat, or when you cannot find the source: high and tight, over clothing. When the source is found and time allows: on bare skin 2–3 in. above the wound, never over a joint. Ratchet the tail snug, twist until the bleeding stops, lock it, record the time.

Who carries it

Military, law enforcement and anyone armed carry it on their person. EMS, fire and civilians keep it as close as possible — belt, gear bag, go bag, vehicle.

12 things to know about the TMT

Where it came from, how the strap and lock differ from a classic windlass, which part number is which, and what the data show.

01

Who makes it

Safeguard Medical. The TMT was brought to market by Combat Medical — founded by a former U.S. Army Special Forces medical sergeant and now a division of Safeguard — and Safeguard describes it as designed by the U.S. military.^4,8 It is made in the USA;³ the U.S. instructions name Alphapointe of Brooklyn, New York, as manufacturer,⁵ and Safeguard notes a workforce that includes blind and low-vision employees.⁸
02

evidence-based standard since 2019

The evidence-based added the TMT to its limb tourniquet list in its 2019 update — the first since 2005 — under NSN 6515-01-656-6191, the number Safeguard assigns to its Berry-compliant TMT, part 31-115.^2,3,9
03

A 2-inch strap

Half an inch wider than the C-A-T's 1.5 in. strap.¹⁵ Safeguard states the wider strap achieves occlusion at lower pressures.⁴
04

No internal band

Where the C-A-T runs a band inside its strap, the TMT has none. Safeguard states this eases slack removal and allows rapid resetting.⁴
05

Ratchet the slack out

You do not just pull and fasten: grip the tail close to the buckle, pull up and away from the body, then down in a quick ratcheting motion, and repeat until the strap is snug — then twist.⁵
06

Two locks and a click

A double-routed speed buckle and a hook-and-loop-backed strap hold tension, and the torsion bar gives an audible click when it seats in its retaining clip.^4,5
07

A buckle that comes apart on purpose

The quick-disconnect buckle prevents misrouting of the tail and lets you open the loop, pass the strap around a trapped limb and reconnect it — or apply it one-handed.^4,5
08

Built to be stored out of the package

A UV-protective additive in the polymers makes the TMT, in Safeguard's words, durable enough to be stored outside of its packaging. Store it in the one-handed configuration.^4,5
09

The widest labeled range of the three

Safeguard labels the TMT for limbs 5.75 to 38 in. (14.6–96.5 cm) around⁴ — against up to 35 in. for the C-A-T¹⁵ and 5.75 to 32.5 in. for the SAM XT.¹⁶
10

It pairs with the TQ-RAM

The TQ-RAM™ attaches to the TMT to give hands-free compression on top of a packed wound, and to control compressible bleeding in areas a limb tourniquet cannot reach.^4,7
11

What the data show

In 24 British military volunteers self-applying at mid-thigh, the TMT succeeded in 71% and the C-A-T in 92% — not a significant difference — with median occlusion times of 35 and 37.5 seconds.¹⁰ In a three-way crossover, arm failure was 19.4% for the TMT, 5.6% for the C-A-T Gen 7 and 58.3% for the SOFTT-W, and the C-A-T was faster.¹¹ On a manikin thigh, the TMT and the C-A-T controlled bleeding equally often, the C-A-T at higher pressure.¹²
12

Three part numbers, two colors

PDF185 is the civilian black TMT (CE-marked, NSN 6515-99-258-6320) and PDF186 the orange; both carry a 7-year shelf life. Part 31-115 is the Berry-compliant black TMT (NSN 6515-01-656-6191), purchased through DAPA, GSA and VA DAPA, with a 10-year shelf life from manufacture.^3,4 Every version is an FDA-registered, Class I (510(k)-exempt) nonpneumatic tourniquet.⁶

How to apply the TMT

Safeguard's one-handed sequence, with the placement decision made first.

1

Choose the placement. Under threat, or when you cannot see where the blood is coming from: hasty — high and tight, as close to the body as the limb allows, over clothing. When the source is found and time and safety allow: deliberate — on bare skin, 2–3 in. above the wound. If that point lands on a joint, move above the joint. Never place it across or directly over a joint.^1,5
2

Let it fall open. Hold the end of the strap by the white time-label tab and let the TMT fall open, with the word "PULL" facing away from you. For a trapped limb or a two-handed application, separate the buckle, pass the strap around the limb without twisting it, and reconnect.⁵
3

Free the strap. Slide the loop onto the limb at your chosen placement, then pull the time tab until the hook-and-loop separates.⁵
4

Ratchet it snug. Grip the tail close to the buckle, pull up, out and away, then down in a quick ratcheting motion. Repeat until the strap is snug around the limb.⁵
5

Twist. Rotate the TMT for easy access to the torsion bar and twist until the bleeding stops and the distal pulse is gone. It hurts — that is expected, and it is not a reason to loosen it.^1,5
6

Lock, secure, record. Lock the torsion bar into the retainer — listen for the click — and secure the excess strap with its hook-and-loop. Write the time on the tourniquet and the casualty card. If bleeding continues, add a second tourniquet side by side with the first.^1,5
7

Reassess a hasty tourniquet. When the scene allows, expose the wound. If a tourniquet is needed, place a second one on bare skin 2–3 in. above the bleeding site, tighten it, then slowly release the first. If the source still cannot be found, the first stays high and tight.¹
8

Leave it on — or convert by protocol. For civilians and most law enforcement, especially in self-aid, leaving it in place for the receiving clinicians is good practice. The TCCC Guidelines direct every effort to convert within 2 hours when the casualty is not in shock, the wound can be watched, and it is not an amputation.¹

Train it — then carry a fresh one. The TMT is labeled a single-use device;⁵ a unit ratcheted and twisted in practice stays a training unit — mark it and keep it out of duty kits. Drill the one-handed sequence on each arm and leg, the trapped-limb route, and both placements.

Where it fits

Use it for

Life-threatening bleeding from an arm or a leg¹
Any traumatic amputation of an arm or leg — even one that is barely bleeding¹
A trapped limb — open the quick-disconnect buckle, route around, reconnect^4,5
Limbs from 5.75 to 38 in. (14.6–96.5 cm) around⁴

Not for

The groin, armpit or neck — pack those wounds with hemostatic gauze and hold pressure
Across or directly over a joint — move above it
Over keys, phones or other solid objects in clothing
Bleeding that direct pressure or a pressure dressing controls
Reuse — it is labeled single-use⁵

The evidence

The studies behind the numbers above, what each one tested, and how strong it is.

Study	Evidence type	What was studied	What it found
*Kragh et al., Ann Surg* 2009**	Human · combat clinical	Tourniquets as a class: 232 casualties with 428 tourniquets, Baghdad, 2006	Survival 90% when tourniquets were applied before shock vs 10% after; no limb lost because of a tourniquet
*Beaven et al., J Spec Oper Med* 2018**	Human volunteer · randomized	24 British military volunteers self-applying the C-A-T and the TMT at mid-thigh, ultrasound of popliteal flow	Success C-A-T 92% vs TMT 71% (not significant); median time to occlusion 37.5 s vs 35 s; pain scores similar
*Treager et al., J Trauma Acute Care Surg* 2021**	Human volunteer · randomized crossover	C-A-T Gen 7 vs TMT vs SOFTT-W on arm and leg, Doppler pulse, then retested after crawling and dragging	Arm failure 5.6% vs 19.4% vs 58.3%; arm time 37.8 s vs 65.0 s vs 63.1 s; leg failure 27.8% vs 44.4% vs 61.1%; no difference after movement
*Gibson et al., J Spec Oper Med* 2016**	Manikin	TMT and RATS vs C-A-T on a manikin thigh, two users, 30 tests each	Effectiveness and pulse cessation did not differ by model; the C-A-T applied more pressure than the TMT
*Montgomery et al., J Spec Oper Med* 2019**	Expert review · evidence-based update	Review of limb tourniquets for the evidence-based's 2019 update	evidence-based voted to update its list in April 2019; the authors note the lack of unbiased data and official test criteria

Strongest to weakest: human clinical data, then human-volunteer tests, then manikin studies, then expert review. The combat data are for tourniquets as a class.¹³ The two volunteer studies point the same way: the TMT works, and it does not outperform the C-A-T.

Questions buyers ask

▾Is the TMT evidence-based standard?

Yes. The Evidence-Based Standard Devices & Adjuncts list names the Tactical Mechanical Tourniquet, NSN 6515-01-656-6191.² The orange TMT is the same device in a high-visibility color.⁴

▾Which part number do I need?

Black PDF185 is the civilian TMT — CE-marked, NSN 6515-99-258-6320, 7-year shelf life. Black 31-115 is the Berry-compliant TMT for DAPA, GSA and VA DAPA purchasing — NSN 6515-01-656-6191, 10-year shelf life. Orange is PDF186, 7-year shelf life.^3,4

▾High and tight, or 2–3 inches above the wound?

Both are correct; the situation decides. Under threat, or when you cannot find the source, place it high and tight over clothing. When the source is found and time allows, place it on bare skin 2–3 in. above the wound — and if that lands on a joint, go above the joint. Reassess a hasty tourniquet once the scene allows and convert it to a deliberate one; if the source still cannot be found, it stays high and tight.¹

▾How tight is tight enough?

Until the bleeding stops and the pulse below the tourniquet is gone.^1,5 Ratchet the tail snug before you twist. A correctly tightened tourniquet hurts; that pain is expected and is not a reason to loosen it.

▾Can I put it on myself with one hand?

Yes — the TMT has a dedicated one-handed sequence, and the quick-disconnect buckle allows one-handed or trapped-limb application.^4,5 Practice it on both arms before you need it.

▾What if one tourniquet doesn't stop the bleeding?

Twist further. If that fails, apply a second tourniquet side by side with the first and reassess.¹

▾How long can it stay on — and should it come off?

For civilians and most law enforcement, especially when you applied it to yourself, leaving it on for the hospital team is good practice. The military direction: every effort is made to convert within 2 hours if the casualty is not in shock, the wound can be watched, and it is not an amputation; non-medical service members do not attempt it past 2 hours without direction from advanced medical personnel, and a tourniquet on longer than 6 hours stays on unless close monitoring and lab capability are available.¹ Long rural or remote transports are where conversion becomes a real question.

▾Should a tourniquet go on an amputation that is barely bleeding?

Yes. The TCCC Guidelines call for a limb tourniquet on any traumatic amputation.¹ Early on, adrenaline clamps the torn arteries down; when it wears off they open again and the bleeding starts.

▾Will it work on a child?

Safeguard labels the TMT for limbs from 5.75 in. (14.6 cm) around.⁴ Most commercial tourniquets work on most children; the pediatric studies used the C-A-T, which stopped the arterial pulse in every arm and 93% of thighs of 60 children aged 6 to 16.¹⁴ Most limb injuries in children never need a tourniquet: escalate from direct pressure to a pressure dressing first. For children 2 and under, direct pressure or a pressure wrap is the better tool.

▾How should I carry and store it?

Take it out of the package, set it in the one-handed configuration, and keep it in a holster or pouch, out of the weather — especially on body armor.^4,5 Military, law enforcement and anyone armed carry it on their person; everyone else as close as possible. Replace it at the end of its shelf life — 7 or 10 years from manufacture by part number.⁴

▾Can I reuse a TMT?

No. It is labeled a single-use device;⁵ one applied on a casualty or used in training is retired from duty.

FREQUENTLY ASKED QUESTIONS

Is the TMT Tourniquet CoTCCC recommended?

Yes. The Tactical Mechanical Tourniquet (TMT) by Alphapointe is CoTCCC-recommended by the Committee on Tactical Combat Casualty Care, and has also been DoD tested for efficacy. Over one million units have been produced and fielded across U.S. military and law enforcement. It carries NSN 6515-01-656-6191 and is manufactured through the AbilityOne program, making it a compliant option for federal procurement.

What makes the TMT's dual-locking mechanism different from other tourniquets?

Most windlass tourniquets use a single lock — typically a clip or ring that captures the torsion bar. The TMT uses a dual-locking system with both a primary lock and a secondary retention feature. When properly engaged, the torsion bar produces an audible click that confirms it is locked. This eliminates a critical point of failure: inadvertent windlass release during patient movement or extrication, which can cause re-bleeding. The audible confirmation is especially valuable in noisy environments or when wearing thick gloves.

Why is the TMT's 2-inch band width significant?

A wider tourniquet band distributes occlusive pressure over a larger surface area, requiring less force per square inch to achieve arterial occlusion. This reduces the risk of localized tissue and nerve injury under the tourniquet, an important consideration in prolonged field care (PFC) scenarios where a tourniquet may be in place for an extended period. The TMT's 2" band is wider than the 1.5" bands used by the CAT Gen 7 and SOF-T, and research suggests wider bands may be associated with lower rates of tourniquet-related nerve injury.

Can the TMT be linked to the TQ-RAM pressure point device?

Yes. The TQ-RAM is specifically designed as a TMT accessory. The TQ-RAM's arched dome provides targeted, hands-free compressive pressure directly over a packed wound or junctional bleed site — areas where a tourniquet cannot be placed (groin, axilla). By coupling the TQ-RAM to the TMT strap, medics can maintain pressure while simultaneously performing other critical interventions on the casualty, a significant advantage in a resource-constrained environment.

What is the shelf life of the TMT Tourniquet?

The TMT has an indefinite shelf life in a controlled storage environment and up to 10 years in operational (field) storage conditions. The co-poly resin acetal construction with IR/UV protective additives resists UV degradation, chemical exposure, and extreme temperatures, maintaining structural integrity across a wide range of environmental conditions. This makes the TMT suitable for long-term vehicle and facility kit staging without routine replacement cycles.

What does 'CoTCCC-recommended' mean for the TMT Tourniquet?

The Committee on Tactical Combat Casualty Care (CoTCCC) publishes a list of recommended limb tourniquets based on performance testing, clinical data, and field use evidence. CoTCCC-recommended status indicates the TMT has met the standards the committee uses to evaluate tourniquet efficacy and reliability for battlefield use. Per Safeguard Medical product documentation, the TMT is on the CoTCCC-recommended list and has undergone DoD testing with over one million units fielded. Note: CoTCCC uses 'recommended' — not 'approved' or 'certified' — as the official designation.

What makes the TMT's 2-inch band width clinically significant?

A wider tourniquet band distributes occlusive pressure over a larger surface area on the limb, which means adequate arterial occlusion can be achieved at lower applied pressure per unit area. Lower pressure reduces the risk of localized nerve compression and pressure-related tissue injury during prolonged tourniquet application. The TMT's 2" band is wider than the 1.5" bands on the C-A-T Gen 7 and SOF-T, and this difference is most relevant when prolonged field care extends tourniquet dwell time beyond 2 hours.

How does the dual-locking mechanism on the TMT prevent windlass bar failure?

Windlass bar slippage is a documented failure mode in some tourniquet designs — after twisting to occlusion, the torsion bar can partially unwind, reducing pressure. The TMT uses a dual-lock system: a primary lock captures the bar, and a secondary retention feature provides backup engagement. The audible click confirms both locks are engaged. This dual confirmation is particularly valuable in low-light or high-noise environments where visual or tactile verification alone may be unreliable.

Can the TMT be applied two-handed if one-handed application isn't possible?

Yes. The torsion bar on the TMT is designed to separate from the main body, allowing the bar to be removed and reattached for conventional two-handed windlass application. This is useful when applying a tourniquet to another casualty or when fine motor degradation prevents reliable one-handed technique. The same bar design supports both self-aid (one-handed) and buddy-aid (two-handed) application without requiring a separate device.
