A big, sterile, non-stick pad with its own gauze roll — the dressing for wounds and burns too large for a 4 × 4, and a sound base layer under a firmer elastic wrap.
At a glance
9 things to know about the Dyna-Stopper
What is in the pouch, what it does well, and where it sits next to tourniquets, packing gauze and pressure bandages.
-
01
A large pad, folded small
The dressing folds to 3½ × 5½ in. and unfolds to 9 × 5½ in. to cover larger injuries.3,4
-
02
A non-adherent face
The padding is non-adherent, so it does not stick to the wound bed — gentler to put on and to take off.3 Absorbent gauze and cotton padding soak up blood and drainage.3
-
03
The gauze roll makes it a pressure dressing
A removable stretch gauze roll comes in the pouch for extra pressure and coverage; the package labels it for use as a pressure bandage.3,5 Dynarex designs the dressing so compression can be adjusted to the level you want.3 For more pressure than gauze gives, wrap an elastic bandage over the top.
-
04
Burns and big wounds
The expandable non-stick pad is labeled for wound or burn coverage.5 For burns, the TCCC Guidelines call for dry, sterile dressings over the burned area.1
-
05
A sling or a splint tie
The flexible cotton adapts as a bandage, an arm sling or a tie to secure a splint.3,5
-
06
Not a tourniquet, not a hemostatic
Life-threatening bleeding from a limb that a tourniquet can control gets a tourniquet.1 A deep or junctional wound is packed first — a firm power ball directly on the bleeding vessel, every corner packed tight, hemostatic gauze where you have it1 — and the Dyna-Stopper goes over the top.
-
07
Pressure depends on the wrap
In a sensor study of 124 emergency providers, peak pressure under hand-applied dressings ranged from 50 to 412 mmHg, and the bandage material and wrapping technique drove the difference.6 Wrap the roll firmly and check circulation beyond it.
-
08
Sterile and latex-free labeling
Each dressing is sterile unless the package is opened or damaged, single use, and labeled as not made with natural rubber latex.4,5 Dynarex packs 60 to a case.3,4
-
09
Class I
Dynarex lists it with the FDA as an elastic bandage (product code FQM), Class I and 510(k)-exempt.4
How to use the Dyna-Stopper
The doctrinal order for bleeding first, then the dressing.
-
1Tourniquet first on a limb. Life-threatening limb bleeding that a tourniquet can control gets a tourniquet. Under threat, or when you cannot see the source: high and tight, over clothing. Once the wound is exposed: on bare skin 2–3 in. above it. Never across a joint.1
-
2Pack a deep wound first. Power ball directly on the bleeding vessel, every corner packed tight. Never pack the chest or abdomen; pack the neck with care, without compressing the airway. Hold pressure: hemostatic gauze at least 3 minutes1 or its labeled time, plain gauze at least 10 minutes, and in every case until the bleeding stops.
-
3Open the pad. Open the pouch, unfold the pad as far as the wound needs — up to 9 × 5½ in. — and place the non-adherent side on the wound or over the packing.3
-
4Wrap the gauze roll. Wrap the stretch gauze roll firmly over the pad and around the limb to hold pressure, and secure the end.3,5
-
5Add elastic if you need more. An elastic wrap such as READY WRAP™ or an ACE-type bandage over the gauze adds pressure and frees your hands; a bandana or strip of cloth works when nothing else is available.
-
6Check beyond the wrap. Color, warmth, sensation and pulse below it. If circulation is cut off and no tourniquet is intended, loosen and rewrap.
-
7If it bleeds through. On a superficial wound, or one under the dressing that is not deep enough to pack: leave the dressing on and add gauze and another wrap on top. On a packed wound that keeps bleeding: remove the packing and repack it.1
-
8Burns: cover, do not squeeze. Lay the opened pad dry over the burn and hold it in place loosely.1,5
Where it fits
- Large wounds and abrasions that need a big, non-stick, absorbent cover3
- Burns — a dry, sterile cover1,5
- Bleeding that firm pressure can control, using the stretch gauze roll3,5
- A cover layer over a packed wound, and a sling or splint tie3
- Life-threatening limb bleeding a tourniquet can control — tourniquet first1
- Replacing packing or a hemostatic in a deep or junctional wound
- The chest or abdomen — never pack into either
- Situations needing strong, sustained compression — add an elastic wrap or use a pressure bandage
The evidence
No study has tested the Dyna-Stopper itself. These are the guideline and the pressure-dressing evidence behind the advice above.
| Study | Evidence type | What was studied | What it found |
|---|---|---|---|
| TCCC Guidelines, 1 May 2026 | Expert review · guideline | Massive hemorrhage, hemostatic dressings, burns | Tourniquet first for limb bleeding amenable to one; hemostatic dressings with at least 3 minutes of direct pressure; cover burns with dry, sterile dressings |
| Evidence-Based Standard Devices & Adjuncts, 15 December 2021 | Expert review · device list | Devices recommended for combat casualty care | — |
| Brauckmann et al., Eur J Trauma Emerg Surg 2026 | Simulation · pressure sensors | 124 emergency providers (116 analyzed) applying pressure dressings of their choice over calibrated sensors | Peak pressure 169 ± 84 mmHg (range 50–412); wrapping technique was the strongest predictor, then bandage material; providers' estimates did not match measured pressure |
The Dyna-Stopper is a Class I, 510(k)-exempt dressing; there is no device-specific outcome data. For life-threatening bleeding, the evidence base belongs to tourniquets and the evidence-based standard hemostatic dressings packed underneath any cover dressing.
