Title:	Systems and methods for providing a debriding wound vacuum
Abstract:	Thus, systems and methods for a debriding wound vacuum may include a sponge for application to a wound, a flexible sheet for covering and sealing the wound, and a bladder. The bladder may be in fluid communication with at least a portion of the sponge. The bladder preferably contains a debridement substance. A negative pressure device may form part of the system and may be used to apply negative pressure via a hollow tube to the sponge. The negative pressure device may be adapted to apply negative pressure to the sponge via the hollow tube in order form a seal between the flexible sheet and the wound. The systems may also include microelectronic mechanical valves for releasing the debridement substance from the bladder.

Patent Claims:	1. A debriding wound vacuum for introducing a debridement substance to a wound located on a patient's body, the vacuum comprising: a source for introducing the debridement substance to the wound, wherein the source for introducing the debridement substance to the wound is external to the patient's body; a sponge for application to a wound, the sponge configured to receive a debridement substance from the source; a negative pressure device for applying negative pressure to the wound; a hollow tube for placing the negative pressure device in fluid communication with the sponge; and an optical feedback instrument to send optical signals in real time to a display to provide a health care provider with an indication of the status of the wound. 2. The debriding wound vacuum of claim 1, the sponge further comprising a time-release mechanism that releases the debridetnent substance at a predetermined time. 3. The debriding wound vacuum of claim 1 wherein the sponge is formed from a material that releases the debridement substance at a predetermined time. 4. The debriding wound vacuum of claim 1 wherein the sponge further comprises a chamber including the debridement substance. 5. The debriding wound vacuum of claim 4 further comprising a microelectronic mechanical valve for releasing the debridement substances from the chamber. 6. The debriding wound vacuum of claim 5, the microelectronic mechanical valve that comprises a receiver for receiving wireless signals. 7. The debriding wound vacuum of claim 1 wherein the sponge further comprises an elastic bladder including the debridement substance. 8. The debriding wound vacuum of claim 7 further comprising a microelectronic mechanical valve for releasing the debridement substances from the bladder. 9. The debriding wound vacuum of claim 1 wherein said debridement substance comprises introducing a tissue digesting enzyme. 10. The debriding wound vacuum of claim 1 wherein the debridement substance comprises collagenase. 11. A debriding wound vacuum for introducing a non-naturally occurring debridement substance to a wound located on a patient's body, the vacuum comprising: a source for introducing the non-naturally occurring debridement substance to the wound, wherein the source for introducing the debridement substance to the wound is external to the patient's body; a sponge for application to a wound, the sponge configured to receive a debridement substance from the source; a negative pressure device for applying negative pressure to the wound; a hollow tube for placing the negative pressure device in fluid communication with the sponge; and an optical feedback instrument to send optical signals in real time to a display to provide a health care provider with an indication of the status of the wound. 12. A debriding wound vacuum for introducing a non-wound-generated debridement substance to a wound located on a patient's body, the vacuum comprising: a source for introducing the non-wound-generated debridement substance to the wound, wherein the source for introducing the debridement substance to the wound is external to the patient's body; a sponge for application to a wound, the sponge configured to receive a debridement substance from the source; a negative pressure device for applying negative pressure to the wound; a hollow tube for placing the negative pressure device in fluid communication with the sponge; and an optical feedback instrument to send optical signals in real time to a display to provide a health care provider with an indication of the status of the wound. 13. A debriding wound vacuum for introducing a debridement substance to a wound located on a patient's body, the vacuum comprising: a source for introducing the debridement substance to the wound, wherein the source for introducing the debridement substance to the wound is external to the patient's body; a sponge for application to a wound, the sponge configured to receive a debridement substance from the source; a negative pressure device for applying negative pressure to the wound; a hollow tube for placing the negative pressure device in fluid communication with the sponge; and an optical feedback instrument to send optical signals in real time to a display to provide a health care provider with an indication of the status of the wound.
