Natrox™ Oxygen Wound Healing
NATROX® Oxygen Wound Therapy System is a class II medical device licensed under Medical Device Directive 93/42/EEC. The system consists of two main elements; the NATROX® Oxygen Generator and the NATROX® Oxygen delivery system.
The NATROX® Oxygen Generator is a battery-operated device which delivers 98% pure humidified oxygen to the wound bed through water electrolysis. It is supplied with two rechargeable batteries and a charging kit, thus allowing the user complete freedom of movement. Each battery will last for a minimum of 30 hours ; however, users should be advised to keep one on charge whilst using the other and changing them over daily.
The NATROX® Oxygen Delivery System is a sterile, single-use wound interface. Its “web” like design allows free passage of wound exudate into the secondary dressing whilst optimising the flow and diffusion of oxygen across the wound bed. It has a 1 m long thin flexible tube which connects directly to the NATROX® Oxygen Generator. The NATROX® Oxygen Delivery System should be changed at each dressing change in accordance with good clinical practice. However, it can remain in place for up to 7 days if clinically appropriate.
