Abstract
This invention provides wound healing systems, which delivers oxygen to the wound bed and applies negative pressure thereto, where the source of oxygen and negative pressure are simultaneously applied to distal sites of the dressing. Methods of treating wounds and methods of treating or preventing anaerobic infection of wounds using such systems are described.

45. A wound healing system, comprising:
-
a dressing for wound containment; a first inlet in said dressing, wherein said first inlet is operationally connected to a source for the application of negative pressure to a wound covered by said dressing; a second inlet in said dressing, wherein said second inlet is located distally to said first inlet and wherein said second inlet is operationally connected to a source for the application of oxygen flow, which conducts oxygen to a wound covered by said dressing; and a regulator for said source for the application of negative pressure to supply at least 20-500 mmHg of pressure. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)
-
- 71. A method of treating a wound in a subject, said method comprising the steps of applying a source of oxygen containing to a wound in said subject and concurrently applying negative pressure to said wound, wherein said source of oxygen maintains oxygen at a value of at least 21% of the total gas in said source and whereby application of oxygen and negative pressure to said wound stimulates wound healing.
- 79. A method of treating or preventing anaerobic infection of a wound in a subject, said method comprising the steps of applying a source of oxygen containing to a wound in said subject and concurrently applying negative pressure to said wound, wherein said source of oxygen maintains oxygen at a value of at least 21% of the total gas in said source and whereby application of oxygen and negative pressure to said wound treats or prevents anaerobic infection of said wound.
