Device and method for treatment of surface infections with nitric oxide
View Patent ↗A device for the topical delivery of nitric oxide gas to an infected area of skin includes a source of nitric oxide gas, a bathing unit, a flow control valve, and a vacuum unit. The bathing unit is adapted to surround the area of the infected skin and form a substantially air-tight seal with the skin surface. The bathing unit is also in fluidic communication with the source of nitric oxide. The flow control valve is position downstream of the source of nitric oxide and upstream of the bathing unit. The flow control valve controls the amount of nitric oxide gas that is delivered to the bathing unit. The vacuum unit is positioned downstream of the bathing unit and is used to withdraw gas from the bathing unit. Application of nitric oxide gas to the infected area of skin reduces levels of bacteria in the infected area and promotes the healing process.
1. A method to promote healing of an area of the body with a lesion, the method comprising the steps of:
providing a flow-controlled source of exogenous nitric oxide-containing gas; and
delivering the exogenous nitric oxide-containing gas to the area of the body so as to topically contact and bathe the lesion with nitric oxide gas.
2. The method of claim 1 , wherein a jet of exogenous nitric oxide-containing gas is delivered to the lesion.
3. A method to promote healing of a lesion, the method comprising the steps of:
identifying the lesion on the surface of a body;
providing a flow-controlled source of exogenous nitric oxide gas;
diluting the exogenous nitric oxide gas;
delivering the exogenous nitric oxide gas to the lesion on the surface of the body, and
topically contacting the lesion with the exogenous nitric oxide gas.
4. The method of claim 3 , wherein a jet of exogenous nitric oxide gas is delivered to the lesion.
5. A method to promote healing of a lesion on a surface of a body, the method comprising the steps of:
providing a source of exogenous nitric oxide gas;
diluting the exogenous nitric oxide gas;
delivering the diluted exogenous nitric oxide gas to the lesion, and
topically contacting the lesion with the exogenous nitric oxide gas.
6. The method of claim 5 , wherein a jet of exogenous nitric oxide is delivered to the lesion.
