Abstract

An apparatus includes a fluid permeable dressing and a cover membrane configured to extend over the fluid permeable dressing. A tube is coupled to the fluid permeable dressing and is configured to apply suction through the fluid permeable dressing. A fluid reservoir is coupled to the cover membrane, the fluid vessel including an inlet port configured to receive a fluid and an outlet port fluidically coupled to the fluid permeable dressing.

Claims

1. An apparatus, comprising:

a fluid permeable dressing;

a cover membrane configured to extend over the fluid permeable dressing;

a tube coupled to the fluid permeable dressing, the tube configured to apply suction through the fluid permeable dressing; and

a fluid vessel integrated with the cover membrane and disposed between the fluid permeable dressing and the cover membrane, the fluid vessel including an inlet port and an outlet port fluidically coupled to the fluid permeable dressing, the outlet port configured to deliver a treatment fluid to the fluid permeable dressing.

2. The apparatus of claim 1, wherein the inlet port of the fluid vessel is a self-sealing needle port.

3. The apparatus of claim 1, wherein the outlet port of the fluid vessel is a regulated drip port.

4. The apparatus of claim 1, wherein the inlet port is spaced less than six inches from the outlet port.

5. The apparatus of claim 1, further comprising a collection canister configured to receive exudate from the fluid permeable dressing via the tube.

6. The apparatus of claim 1, wherein the fluid vessel is coupled to the cover membrane using at least one of a heat weld, a radio frequency (RF) weld, or an adhesive.

7. The apparatus of claim 1, wherein the cover membrane has an outer boundary that surrounds the outer boundary of the fluid vessel.

8. The apparatus of claim 1, wherein the fluid vessel includes a fluid vessel wall having an outer surface substantially enclosed by the cover membrane when the cover membrane extends over the fluid permeable dressing.

9. The apparatus of claim 1, further comprising:

a vacuum pump coupled to the tube, the vacuum pump configured to apply suction to the fluid permeable dressing through the tube, the vacuum pump having a first configuration in which suction is applied to the fluid permeable dressing at a first rate, the vacuum pump having a second configuration in which suction is applied to the fluid permeable dressing at a second rate less than the first rate.

10. The apparatus of claim 1, wherein the entire fluid permeable dressing is pliable.

11. An apparatus, comprising:

a fluid permeable dressing having a region configured to be coupled to a suction source;

a cover membrane configured to extend over the fluid permeable dressing, the cover membrane having an outer boundary; and

a fluid vessel configured to contain a treatment fluid, the fluid vessel including an inlet port configured to receive a fluid and an outlet port fluidically coupled to the fluid permeable dressing, the fluid vessel having an outer boundary surrounded by the outer boundary of the cover membrane, the fluid vessel having a width in a dimension substantially parallel with a plane defined by an upper surface of the fluid permeable dressing and a depth in a dimension substantially perpendicular to the plane defined by the upper surface, the width being greater than the depth.

12. The apparatus of claim 11, further comprising:

a tube coupled to the region of the fluid permeable dressing, the tube configured to apply suction through the fluid permeable dressing.

13. The apparatus of claim 11, wherein the fluid vessel is coupled directly to at least one of an outer surface of the cover membrane or an inner surface of the cover membrane.

14. The apparatus of claim 11, wherein the inlet port of the fluid vessel is a self-sealing needle port.

15. The apparatus of claim 11, wherein the outlet port of the fluid vessel is a regulated drip port.

16. The apparatus of claim 11, wherein the fluid vessel is disposed between the fluid permeable dressing and the cover membrane.

17. The apparatus of claim 11, wherein the inlet port is spaced less than six inches from the outlet port.

18. The apparatus of claim 11, further comprising a collection canister configured to receive and store exudate from the fluid permeable dressing.

19. The apparatus of claim 11, wherein the fluid vessel includes a fluid vessel wall having an outer surface substantially enclosed by the cover membrane when the cover membrane extends over the fluid permeable dressing.

20. An apparatus, comprising:

a fluid permeable dressing having a region configured to be coupled to a suction source;

a cover membrane configured to extend over the fluid permeable dressing; and

a fluid vessel configured to contain a treatment fluid, the fluid vessel coupled to the cover membrane, the fluid vessel including an outlet port fluidically coupled to the fluid permeable dressing, the outlet port configured to control a delivery of the treatment fluid to the fluid permeable dressing, the fluid vessel including an outer boundary substantially coterminous with an outer boundary of the fluid permeable dressing.

21. The apparatus of claim 20, wherein the fluid vessel is coupled directly to the cover membrane using at least one of a heat weld, a radio frequency (RF) weld, or an adhesive.

22. The apparatus of claim 20, wherein the fluid vessel is coupled directly to at least one of an outer surface of the cover membrane or an inner surface of the cover membrane.

23. The apparatus of claim 20, wherein the fluid vessel includes an inlet port, the inlet port of the fluid vessel is a self-sealing needle port.

24. The apparatus of claim 20, wherein the outlet port of the fluid vessel is a regulated drip port.

25. The apparatus of claim 20, wherein the fluid vessel is disposed between the fluid permeable dressing and the cover membrane.

26. The apparatus of claim 20, wherein the fluid vessel includes an inlet port, the inlet port is spaced less than six inches from the outlet port.

27. The apparatus of claim 20, further comprising a collection canister configured to receive and store exudate from the fluid permeable dressing.

28. The apparatus of claim 20, wherein the outlet port of the fluid vessel is directly adjacent to at least one of the cover membrane or the fluid permeable dressing.
