Abstract

A wound vacuum therapy dressing kit is provided for use with a wound drainage system having a vacuum source. The kit may include a wound dressing member, a sealing film, and a wound measurement device. The wound dressing member may include a wound contacting surface configured to be in contact with and generally conform to a wound surface of a patient. The member may be adapted to be coupled to the vacuum source for communicating suction from the vacuum source to the wound surface. The sealing film of the kit may be provided for placement over the member and may be configured to adhere to a patient'"'"'s healthy skin surrounding the wound. The wound measurement device may include a transparent top portion and a transparent bottom portion configured for placement adjacent the wound surface. The top portion may include a drawing surface and a grid associated with the drawing surface.

Claims

1. A wound vacuum therapy dressing kit for use with a wound drainage system having a vacuum source, the kit comprising:

a wound dressing member having a wound contacting surface configured to be in contact with and generally conform to a wound surface of a patient, the member being adapted to be coupled to the vacuum source for communicating suction from the vacuum source to the wound surface,

a sealing film for placement over the member and configured to adhere to a patient'"'"'s healthy skin surrounding the wound, and

a wound measurement device comprising a perforated transparent film without adhesive including a first portion and a second portion removably coupled to the first portion and configured to be pulled from the first portion, the film configured to be folded such that (i) substantially all of a first surface of the first portion contacts a first surface of the second portion and (ii) the second surface of the second portion is configured for placement adjacent the wound surface, a second surface of the first portion including an exposed drawing surface and a grid that overlies the second portion when the first portion is folded relative to the second portion.

2. The kit of claim 1, further including a tube guide configured to be coupled to the healthy skin adjacent the wound and having an aperture configured to receive a portion of a vacuum tube of the wound vacuum drainage system that extends between the member and the vacuum source.

3. The kit of claim 2, wherein the tube guide includes a curved upper surface and the sealing film is configured to drape over and seal to the curved upper surface.

4. The kit of claim 3, wherein the tube guide includes a generally flat bottom surface and an adhesive layer coupled to the bottom surface.

5. The kit of claim 2, wherein the tube guide further includes a first end and a second end spaced apart from the first end to define an opening in communication with the aperture and configured to pass the vacuum tube therethrough for placement of the vacuum tube within the aperture.

6. The kit of claim 1, further including a patch sheet having a first adhesive layer and a second layer removably coupled to the first layer.

7. The kit of claim 6, wherein the first layer of the patch sheet includes patches and strips configured to be removed from the second layer of the patch sheet and placed over unwanted leaks in the film for use with the sealing film to seal about the member and create a vacuum space above the wound.

8. The kit of claim 7, wherein each of the patches has a diameter of ½

inch (12.7 mm), ¾

inch (19.05 mm), or 1 inch (2.54 cm).

9. The kit of claim 7, wherein each of the strips is 6 inches (15.24 cm) in length and has a width of ½

inch (12.7 mm), ¾

inch (19.05 mm), or 1 inch (2.54 cm).

10. The kit of claim 1, wherein the sealing film includes multiple release liners removably coupled to an adhesive back polyurethane layer.

11. The kit of claim 1, wherein the second portion of the wound measurement device includes a ruler.

12. The kit of claim 11, wherein the first portion of the wound measurement device further includes an information recording area for recording a patient'"'"'s data information.

13. A wound vacuum therapy dressing kit for use with a wound drainage system having a vacuum source, the kit comprising:

a generally non-compressible wound dressing member having a wound contacting surface configured to be in contact with and generally conform to a wound surface of a wound,

a sealing film for placement over the member and configured to adhere to a patient'"'"'s healthy skin surrounding the wound,

a patch sheet having a first adhesive layer and a second layer removably coupled to the first layer, the first layer having a patches and strips configured to be removed from the second layer and placed over unwanted leaks in the film,

infection control garments,

applicators configured to measure a depth of the wound, and
