The NATROX™ System is a low-dose tissue oxygenation system intended to provide topical oxygen to aid in the healing of chronic wounds such as:
- Skin ulcerations due to diabetes, venous stasis, post-surgical infections and gangrenous lesions,
- Decubitis ulcers (bedsores), .
- Amputations/infected stumps, .
- Skin grafts,
- Burns, and
- Frostbite
The NATROX™ Topical Oxygen Delivery System is a small battery-powered electronic device approximately the size of a cell phone, containing an oxygen generator that produces 99% oxygen from room air at a rate of approximately 13 mL/hour. A small diameter tube transmits the oxygen to the wound bed, where the wound is exposed to the oxygen atmosphere inside the Oxygen Delivery System (ODS), Island Oxygen Delivery Pad (IODP) wound dressing or into the patient's own wound dressing, The NATROX™ System provides oxygen to diffuse evenly over the wound bed under an occlusive dressing, constantly refreshing the oxygen supply to enhance the normal process of wound healing for chronic and hard-to-heal wounds with compromised oxygen delivery to healing tissue.
The provided text describes the NATROX™ Topical Oxygen Delivery System and its safety and effectiveness. However, it does not contain specific acceptance criteria in a quantifiable format (e.g., "wound size reduction of X% with p-value
§ 878.5650 Topical oxygen chamber for extremities.
(a)
Identification. A topical oxygen chamber for extremities is a device that is intended to surround a patient's limb and apply humidified oxygen topically at a pressure slightly greater than atmospheric pressure to aid healing of chronic skin ulcers such as bedsores.(b)
Classification. Class II (special controls). The special control for this device is FDA's “Class II Special Controls Guidance: Topical Oxygen Chamber for Extremities.” See § 878.1(e) for the availability of this guidance document.
