Fluid pouch, system, and method for storing fluid from a tissue site
The illustrative embodiments described herein are directed to an apparatus, system, and method for storing liquid from a tissue site. The apparatus may include a drape having an aperture, and a fluid pouch coupled to the drape such that the fluid pouch is in fluid communication with the aperture. In one embodiment, the fluid pouch is operable to transfer reduced pressure to the aperture such that the liquid from the tissue site is drawn into the fluid pouch. The fluid pouch may have a cavity that stores the liquid that is drawn from the tissue site. In another embodiment, the fluid pouch may include at least one baffle. The fluid pouch may also include a fluid channel at least partially defined by the at least one baffle. The fluid channel may be operable to store liquid from the tissue site when reduced pressure is applied through the fluid channel.
1. A fluid storage dressing, the dressing comprising:
a cover having a substantially silicone base and at least one aperture, the cover configured to be disposed over a tissue site;
a manifolding layer configured to be disposed over the cover and in fluid communication with the at least one aperture;
an absorbent material configured to be disposed over and in fluid communication with the manifolding layer; and
a sheet configured to be coupled to the cover, the sheet forming at least a portion of a pouch having the manifolding layer and the absorbent material disposed therein.
2. The fluid storage dressing of claim 1 , further comprising an annular adhesive layer configured to be disposed between the cover and the tissue site.
3. The fluid storage dressing of claim 2 , wherein the liquid-air separator is one of a hydrophobic filter and an oleophobic filter.
4. The fluid storage dressing of claim 1 , further comprising a liquid-air separator positioned between an outlet of the fluid storage dressing and a reduced-pressure source.
5. The fluid storage dressing of claim 1 , wherein the absorbent material immobilizes liquid from the tissue site.
6. The fluid storage dressing of claim 1 , wherein at least one of the cover and the sheet are transparent.
7. The fluid storage dressing of claim 1 , wherein the fluid storage dressing is configured to be adhered to a remote tissue site via an adhesive layer.
8. A method of manufacturing a fluid storage dressing, the method comprising:
providing a cover having a substantially silicone base and at least one aperture, the cover configured to be disposed over a tissue site;
disposing a manifolding layer over the cover and in fluid communication with the at least one aperture;
disposing an absorbent material over and in fluid communication with the manifolding layer; and
coupling a sheet to the cover, the sheet forming at least a portion of a pouch having the manifolding layer and the absorbent material disposed therein.
9. The method of claim 8 , wherein the method further comprises coupling an annular adhesive layer to the cover.
