  • Patent number: 6767342
    Abstract: An oxygen bandage system which includes a bandage with first and second sterile pads attached to a covering with an adhesive backing secured thereto is disclosed. Pressure sensitive capsules containing hydrogen peroxide are embedded within the first pad. Covering the first pad is the second pad which has a bottom, wound contacting side and a top side which contacts the first pad. Secured to the top side of the second pad is a film containing potassium manganate. A release liner covers the pads and adhesive backing. In order to use the bandage, the release liner is removed. The bottom side of the second pad is placed over the wound and the adhesive backing is secured to the person's skin surrounding the wound. The hydrogen peroxide is released from the capsule by applying pressure thereto. The first pad contacts the film, thereby activating the film and releasing oxygen to the wound.
