Abstract

The illustrative embodiments described herein are directed to a system and method for administering reduced pressure at a tissue site. The apparatus includes a reduced pressure source. The reduced pressure source generates a reduced pressure. The apparatus includes a tube having a plurality of lumens. The plurality of lumens includes at least one collection lumen. The reduced pressure source applies the reduced pressure to the tissue site through the plurality of lumens such that the at least one collection lumen receives fluid from the tissue site. The at least one collection lumen stores the fluid received from the tissue site.

First claim

We claim:

1. A method for administering reduced pressure to a tissue site, the method comprising:
applying a reduced pressure to the tissue site using a reduced pressure source, the reduced pressure being applied to the tissue site via a plurality of lumens in a delivery tube;
storing liquid from the tissue site in at least one collection lumen in the plurality of lumens; and
determining a liquid level of the liquid in the at least one collection lumen based on a plurality of demarcations located on the delivery tube.

2. The method of claim 1 , wherein the step of storing liquid includes storing the liquid in an absorbent material disposed in the at least one collection lumen.

3. The method of claim 1 further comprising positioning a manifold adjacent the tissue site prior to applying the reduced pressure.

4. An apparatus for administering reduced pressure to a tissue site, the apparatus comprising:
a tube having a plurality of lumens including at least one collection lumen having an absorptive material configured to receive and store liquid from the tissue site;
a plurality of demarcations located on the tube proximate the at least one collection lumen.

5. The apparatus of claim 4 , further comprising at least one filter coupled to the tube.

6. The apparatus of claim 5 , wherein the at least one filter is coupled to an end of the tube.

7. The apparatus of claim 5 , wherein the at least one filter includes at least one of a hydrophobic filter, a hydrophilic filter, and a mechanical valve.

8. The apparatus of claim 4 , wherein the plurality of lumens includes a delivery lumen, the apparatus further comprising: a delivery lumen filter coupled to the delivery lumen.

9. The apparatus of claim 8 , wherein the delivery lumen has a larger cross-section than the at least one collection lumen.

10. The apparatus of claim 8 , wherein the at least one collection lumen is a plurality of collection lumens, and each of the plurality of collection lumens is equidistant from the delivery lumen.

11. The apparatus of claim 8 , wherein the delivery lumen is located along a longitudinal center of the tube.

12. The apparatus of claim 4 , further comprising a manifold coupled to an end of the tube adjacent the tissue site.

13. The apparatus of claim 4 , wherein the tube is substantially transparent.

14. A system for administering reduced pressure to a tissue site, the system comprising:
a reduced-pressure source configured to generate a reduced pressure;
a manifold configured to be positioned over the tissue site;
a sealing member configured to be positioned over the manifold and the tissue site;
a tube configured to be fluidly coupled to the reduced pressure source and the manifold, the tube having a plurality of lumens including at least one collection lumen having an absorptive material configured to receive and store liquid from the tissue site;
a plurality of demarcations located on the tube proximate the at least one collection lumen.

15. The system of claim 14 , further comprising at least one filter coupled to the tube.

16. The system of claim 15 , wherein the at least one filter includes at least one of a hydrophobic filter, a hydrophilic filter, and a mechanical valve.

17. The system of claim 14 , wherein the plurality of lumens includes a delivery lumen, the apparatus further comprising: a delivery lumen filter coupled to the delivery lumen.

18. The system of claim 17 , wherein the delivery lumen has a larger cross-section than the at least one collection lumen.

19. The system of claim 17 , wherein the at least one collection lumen is a plurality of collection lumens, and each of the plurality of collection lumens is equidistant from the delivery lumen.

20. The system of claim 19 , wherein each of the plurality of collection lumens are equidistantly space from adjacent collection lumens.

21. The system of claim 17 , wherein the delivery lumen is located along a longitudinal center of the tube.
