NATROX® Oxygen Wound Therapy

Is a medical device that enables clinicians to prescribe pure humidified oxygen applied directly to a wound to assist healing in complex, chronic or non-healing wounds.

How does it work?

By extracting oxygen from the air and delivering it directly to the surface of the wound through our proprietary soft, flexible, "wheel" shaped Oxygen Delivery System (ODS). The continuous supply of oxygen ensures an oxygen-rich environment around the wound area. The device operates silently to allow for a good night's sleep and provides a continuous flow of pure humidified oxygen.

NATROX® Oxygen Generator (OG)

The size and weight (107g) of a mobile phone, the device comes supplied with two rechargeable batteries. We recommend charging one while the other is in use. A small green light will flash to confirm the oxygen is flowing. There is no 'On/Off' switch. The device will start delivering pure humidified oxygen once a charged battery is inserted. All items in the system are designed to be worn comfortably. The batteries are designed to be easy to change, even for patients with limited faculties, including poor eyesight and limited grip strength.

Oxygen Delivery System (ODS)

The ODS is a single-use, sterile, wheel-shaped interface made of a multi-layer medical grade material. It is soft, supple, and extremely conformable to various wound shapes and depths while maintaining patient comfort. It is placed between the wound and the secondary dressing. The ODS design allows for free passage of exudate into the dressing while continuing to deliver humidified oxygen directly to the wound bed

Clinicians and patients typically prefer wound dressings they are familiar with and use regularly. The ODS is designed so clinical teams have the flexibility to use their dressing of choice. These dressings protect wounds from bacteria and other contaminants while absorbing exudate.

Clinical Evidence

A substantial body of evidence shows that oxygen plays a vital role in enabling wound healing(3). Oxygen is critical to wound healing and is involved at every stage of the healing process(4). However, chronic wounds may see healing stall due to low oxygen levels in the tissues (local hypoxia). This remains a challenge for most clinical units, as no easy, quick, inexpensive measurement of this parameter is available for routine use.
