Clinical Case Studies

Numobag® may be used to:

• Contain biological, chemical and nuclear attacks

• Treat single or mass casualties

• Create an instant, disposable isolation unit

• Stop advancement of insidious forms of biological attack: dermal anthrax, smallpox, necrotizing fasciitis, etc.

• Heal large skin lesions


THOT® heals more often, faster and with less scarring than traditional treatment of skin wounds. It was used to treat 9/11 World Trade Center burn victims with favorable results. The U.S. military is currently using Numobag® in Iraq.


Clinical Case studies:


Figure 1: Chemical Burn

(a) Third degree burns caused by a boiling oil spill on the left hand that caught fire.

(b) Healing following one week treatment with the Numobag®. (c) and (d) are two views showing complete healing following 3 weeks of Numobag® (12 treatments). Although there is loss of pigment due to the depth of the burn, there is no clinical scarring, no loss of sensation, and no loss of function. 


Figure 2: Electrical Burn

(a-c) Sixteen third degree burns induced by electric current. Note presence of recurrent necrotic tissue following sharp debridement under anesthesia. (d-f) healing with minimal scarring following 4 weeks of the Numobag®.


Figure 3: Necrotizing Fasciitis

(a) Necrotizing fasciitis with gangrenous eschar; (b) base of ulcer showing exposed tendons and bone following debridement; good granulation tissue following 2.5 weeks the Numobag®, (c) abundant granulation tissue following 6 weeks of the Numobag.


Figure 4: Traumatic Crush Injury

(a) Traumatic crush injury (Stage IV) wound, following impaling of thigh on a stake during a motocross accident; note exposed ripped nerves (single arrow) (b) healing of wound after 4 weeks (12 treatments) of the Numobag® with minimal scarring and no loss of sensation or motor function.


Figure 5: Chronic Diabetic Ulcer


Figure 6: Philippines Soldier’s Amputation Avoided

The Numobag® provided a rapid healing, low cost treatment and avoided amputation. The Soldier’s wound closed after 12 weeks of treatment.
