Numobag® Case Study – Gunshot Wound

Soldier is wounded. The orthopedic surgeon attached an external fixator, but the wound was so severe that the only medical option for the patient was scheduling for amputation. The Philippine National Police General Hospital care team decided to implement the Numobag® which delivered Topical Hyperbaric Oxygen Therapy (THOT®) to save the patient’s lower limb.

Progression of Healing

The following photos show the progression of healing for a case with the first THOT® session on May 8, 2012 and the last treatment on August 9, 2012. 

The course of treatment was 14 weeks as follows:

  • Weeks 1 – 4:  Four THOT® treatments in each of the four weeks
  • Week 5:  No THOT® treatments; 7-day respite to manage and control oxygen toxicity
  • Weeks 6 – 9:  Four THOT® treatments in each of the four weeks
  • Week 10:  No THOT® treatments; 7-day respite to manage and control oxygen toxicity
  • Weeks 11 – 14:  Four THOT® treatments in each of the four weeks
  • Week 15:  One THOT® treatment

Soldier’s Hospital Room

The soldier was treated in this hospital. The Numobag® can be deployed in hospital, clinic, and home settings where oxygen is available. Electricity is not required for Topical Hyperbaric Oxygen Therapy so this treatment is suitable for locations without dependable electricity.
