The Case 95 patient was successfully treated at age 95 with Topical Hyperbaric Oxygen Therapy (THOT®) for a Stage IV necrotic wound. The patient later celebrated her 100th birthday with both legs. Read more about her case and see photos here.
The Numobag® Kit generates Topical Hyperbaric Oxygen Therapy (THOT®), a treatment process that has been developed by scientists over more than 25 years of clinical research. Rather than traditional hyperbaric oxygen therapy that increases systemic blood levels of oxygen, THOT® uses medical grade oxygen topically with the Numobag®.
The Numobag® is a patented, FDA-cleared Class II medical device. It is a thin, transparent, disposable membrane bag that covers the legs and approximately 75% of the human torso. The membrane is composed of a polyethylene material that is considered “extremely clean,” although not sterile. The Numobag® is filled with medical grade oxygen at the correct atmospheric pressure.
Numotech, Inc. has conducted research with Sandia National laboratories to enhance the Numobag® and to ensure its safety.
The Numobag® significantly speeds healing and improves quality of life for patients with:
- Diabetic ulcers
- Pressure sores
- Burns–thermal and chemical
- Skin grafts
- Amputations
- Post surgical infections
- Plastic surgery wounds
- Traumatic wounds

Why Numobag®?
- Proven clinical efficacy and published research. See Publications.
- The Numobag® uses medical grade oxygen.
- Oxygen pressure in the Numobag® does not occlude blood flow in the capillaries.
- Taping the Numobag® to the body at the nipple line does not interfere with blood flow to a wound.
- Numobag® polyethylene is cleaned to 1000 cert (ISO 6) which lessens the risk for bacterial contamination and toxic reactions of contamination particles with oxygen.
- Numobag® polyethylene does not emit toxic gases.
- For a more detailed explanation of items 1-6, refer to UCLA’s evaluation comparing the Numobag® to other topical hyperbaric oxygen therapy devices. A UCLA professor of medicine invented the technique of low pressure topical hyperbaric oxygen therapy for re-vascularizing gangrenous and diabetic ulcers..
- One day, 8 CEUs, Numobag® training program for nurses including safety.
- The Numobag® is disposable membrane eliminating cross contamination between patients.
- Patients can be treated in the hospital, at a clinic, or at home by medical personnel or by trained family members or friends.
