Abstract

A negative wound pressure therapy apparatus includes a wound dressing for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around wound tissue. The apparatus also includes a fluid conduit in fluid communication with the reservoir. The fluid conduit defines a fluid flow path for carrying fluids from the reservoir. The apparatus also includes a vacuum source in fluid communication with the fluid conduit. The vacuum source is suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound. The apparatus also includes at least one biomedical electrode mounted with respect to the wound dressing for transmitting electrical energy to stimulate healing of the wound tissue.

Claims

1. A negative wound pressure therapy apparatus comprising:

a wound dressing for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around wound tissue;

a fluid conduit in fluid communication with the reservoir and defining a fluid flow path for carrying fluids from the reservoir;

a vacuum source in fluid communication with the fluid conduit, the vacuum source suitable for providing an appropriate negative pressure to the reservoir to stimulate healing of the wound tissue; and

at least one biomedical electrode mounted with respect to the wound dressing for transmitting electrical energy to stimulate healing of the wound tissue.

2. The apparatus according to claim 1, further comprising a vacuum port adapted for connection to the fluid conduit, the vacuum port being coupled with the wound dressing to distribute negative pressure to the wound tissue.

3. The apparatus according to claim 2, wherein the vacuum port includes a connector, the connector adapted to couple with the at least one biomedical electrode to establish electrical communication therebetween.

4. The apparatus according to claim 3, wherein the connector is adapted to releasably couple with the at least one biomedical electrode.

5. The apparatus according to claim 2, wherein the vacuum port is integrally formed with the fluid conduit.

6. The apparatus according to claim 2, wherein the at least one biomedical electrode is disposed within the vacuum port.

7. The apparatus according to claim 1, further comprising an insulative material disposed between the at least one biomedical electrode.

8. The apparatus according to claim 1, wherein the wound dressing defines a flow path from the wound tissue to the fluid conduit for carrying fluids from the reservoir.

9. The apparatus according to claim 1, wherein a power source is operably coupled to the wound dressing.

10. The apparatus according to claim 1, wherein the fluid conduit is configured to electrically connect the at least one biomedical electrode to a power source.

11. The apparatus according to claim 1, wherein the wound dressing includes a conductive adhesive layer disposed about an underside of the at least one biomedical electrode and configured to adhere the at least one biomedical electrode to skin adjacent the wound tissue.

12. The apparatus according to claim 1, wherein the at least one biomedical electrode is at least a pair of biomedical electrodes mounted with respect to the wound dressing, the pair of biomedical electrodes configured to transmit electrical energy to stimulate healing of the wound tissue.

13. The apparatus according to claim 12, wherein the pair of biomedical electrodes are separated by an insulative material.

14. The apparatus according to claim 12, wherein the pair of biomedical electrodes are generally arcuate in shape to at least partially surround a flow path defined through the wound dressing, the flow path configured to carry fluids from the reservoir.

15. The apparatus according to claim 12, wherein one of the pair of biomedical electrodes is configured to transmit electrical energy through the wound tissue to the other biomedical electrode to stimulate healing of the wound tissue.
