Game-changing technology leveraging existing global medical oxygen infrastructure to deliver continuous topical oxygen moist wound therapy. FDA-registered, clinically validated, and patent-protected. Delivering the healing power of the oxygen molecule to millions worldwide.
The brainchild of a Neonatal Intensive Care Nurse — we patented and built a family of products in different configurations and sizes so that every wound on any location on any patient can be treated with the same proven protocol.
All types and stages — diabetic foot ulcers, venous leg ulcers, pressure ulcers, surgical wounds, incontinence-associated dermatitis, moisture-associated skin damage, dermatitis. Purpose-built configurations for perineal and non-perineal locations.
One clinical protocol across acute care, long-term care, home health, community, military, and VA settings. No specialized equipment or training required.
Pediatric through geriatric. The same therapeutic approach for a newborn with dermatitis and a 96-year-old with a Stage 4 pressure ulcer.
The clinical debate is over. Topical oxygen therapy is now recognized as an evidence-based intervention for hard-to-heal wounds by every major international wound care body. The question is no longer whether topical oxygen works — it's about which technology delivers it best.
Highest evidence rating for diabetic foot ulcer treatment — Level 1, supported by well-designed RCTs.
TOT should be instituted when diabetic foot ulcers fail standard care — supported by multiple high-quality RCTs and five systematic reviews.
TOT is an accepted intervention for non-healing diabetic foot ulcers where standard care has failed.

We've joined the advanced wound dressing industry with a game-changing technology strategy: leveraging the existing global infrastructure of medical oxygen to heal millions everywhere—without expensive proprietary equipment.
Works with existing medical oxygen in every hospital, nursing home, and portable concentrator worldwide. Zero capital equipment required.
A fraction of the cost of legacy topical oxygen systems and advanced dressings, while enabling 24-hour continuous moist wound therapy.
No controllers, no electronics, no setup complexity. Apply like a dressing, connect standard oxygen hose. Minimal training required.
Large and small health systems can achieve substantial cost savings by replacing topical oxygen systems and costly wound dressings with our patented RashEndZ technology.
The world's first patented occlusive wound dressing engineered for continuous gas delivery — enabling existing medical oxygen infrastructure worldwide to deliver “Dynamic Oxygen Site Therapy” — DOST™
RashEndZ™ uniquely combines occlusive wound protection with continuous, controlled gas delivery — a capability unavailable with advanced and conventional dressings.
Non-woven fabric · Polyurethane layer · Hydrophilic foam perimeter.
Minimal wound-contact foam perimeter keeps the dressing off fragile tissue.
Connects to all medical oxygen sources — wall outlets, concentrators, or tanks.
Range: 0.5–5.0 L/min. Delivers consistent low-flow moist wound oxygenation.
Designed to overlay other advance dressings — adds oxygen and humidity to wound therapy protocols
Six-step protocol · Continuous topical oxygen moist wound therapy
Do not use if damaged. Handle as Sterile. Peel open pouch at the center. Remove device. No special care required.
Remove non-viable tissue and biofilm, cleansing the area, and controlling any signs of infection. Leave wound tissue exposed.
Place dressing over wound with foam lining placed over and around the wound. Secure with bandage or tape, as preferred.
Secure dressing loosely, with a simple bandage, or with tape at no more than 4 locations around the dressing.
Attach the GasPort™ fitting to a humidified oxygen source using a standard respiratory hose. Set the oxygen flow rate to 1.0 L/min, and adjust up to 5 L/min as needed to maintain wound saturation.
Verify that all connection points and the humidification bottle cap are properly sealed, if using a refillable bottle.
Where oxygen exists, RashEndZ™ can heal. That is every hospital, nursing home, and home health setting on Earth.
