Abstract

The current invention discloses a wound treatment device having a wound covering member, an applicator unit, and two lumens. The wound covering member may cover a wound. Sealing mechanism of the wound covering member may be used to form a sealed wound enclosure over and around the wound. The two lumens, including a negative pressure lumen and an oxygen lumen, connect the wound enclosure to the applicator unit. The applicator may be used to apply alternating and cycling negative pressure and oxygen to the wound enclosure, facilitating the wound healing process. The levels and durations of negative pressure, as well as the purity, amount, and durations of oxygen, may be adjusted by the applicator unit.

Claims

1. :

A wound treatment device, comprising;

a wound covering member having an inner side and an outer side,

wherein the wound covering member covers a wound and the inner side faces the wound,

there is a sealing mechanism on the inner side of the wound treating pad,

and the sealing mechanism encircles the wound, attaches to skin surrounding the wound, and defines a sealed wound enclosure;

a negative pressure lumen connected to the outer side of the wound treating pad;

a negative pressure pump connected to the negative pressure lumen, the pump being capable of applying intermittent negative pressure to the wound enclosure;

an oxygen lumen connected to the outer side of the wound treating pad; and

an oxygen delivery device connected to the oxygen tube, the oxygen deliver delivery being capable of delivering intermittent oxygen to the wound enclosure.

2. :

The wound treatment device of claim 1, further comprising a control mechanism connected to the negative pressure pump and the oxygen delivery system, the control mechanism controls the application of negative pressure and the delivery of oxygen.

3. :

The wound treatment device of claim 1, wherein the negative pressure pump, the oxygen delivery device, and the control mechanism are integrated into a single applicator unit.

4. :

A method to treat a wound, comprising;

covering the wound with a wound covering member and forming a sealed wound enclosure over and around the wound;

applying repeated cycles of wound treatment, wherein each cycle of wound treatment comprises;

applying negative pressure to the wound enclosure for a first duration, and

delivering oxygen to the wound enclosure for a second duration.

5. :

the method to treat a wound as claim 4, wherein the first duration is 30 minutes.

6. :

The method to treat a wound as claim 4;

wherein the second duration is 29 seconds.
