In one example embodiment, a dressing connector is described that provides a first fluid path between a first connector and a second connector, and a second fluid path between a third connector and a fourth connector. A liquid barrier may be disposed in the first fluid path. The first fluid path and the second fluid path are generally exposed to an exterior surface of the dressing connector. In some embodiments, a tube may also be bonded to the third connector to provide a third fluid path between the dressing connector and another component. In more particular embodiments, the liquid barrier may be a filter, such as a hydrophobic bacterial filter, a sintered polymer filter, and/or a charcoal filter.

1. A disposable dressing connector configured to couple a reusable container for collecting exudates to a dressing and to a reduced-pressure source, the dressing connector comprising: a first connector and a second connector having a first fluid path between the first connector and the second connector, the first connector configured to connect the first fluid path to the reduced-pressure source and the second connector configured to connect the first fluid path to the reusable container;a liquid barrier disposed in the first fluid path; anda third connector and a fourth connector having a second fluid path between the third connector and the fourth connector, the third connector configured to connect the second fluid path to the dressing and the fourth connector configured to connect the second fluid path to the reusable container;wherein the first fluid path and the second fluid path are exposed to an exterior surface of the dressing connector. 2. The dressing connector of claim 1, wherein: the first connector is a fitting;the second connector is a first receptacle;the third connector is a port; andthe fourth connector is a second receptacle. 3. The dressing connector of claim 1, further comprising a tube bonded to the third connector. 4. The dressing connector of claim 3, wherein the tube comprises a delivery lumen and a sensing lumen, and further comprising a third fluid path adapted for fluidly coupling with the sensing lumen. 5. The dressing connector of claim 1, wherein the liquid barrier is a filter. 6. The dressing connector of claim 1, wherein the liquid barrier comprises a hydrophobic bacterial filter. 7. The dressing connector of claim 1, wherein the liquid barrier comprises a gel-blocking sintered polymer filter. 8. The dressing connector of claim 1, wherein the liquid barrier comprises a charcoal filter. 9. The dressing connector of claim 1, wherein the first connector is a tapered fitting. 10. The dressing connector of claim 1, wherein the second connector and the fourth connector each comprises a cavity exposed to the exterior surface. 11. The dressing connector of claim 1, wherein the second connector and the fourth connector each comprises a tapered cavity exposed to the exterior surface. 12. The dressing connector of claim 1, wherein the second connector and the fourth connector each comprises a recess within a cavity adapted to engage a ridge on a container fitting. 13. The dressing connector of claim 1, wherein the second connector and the fourth connector each comprises an annular recess adapted to engage a ridge on a container fitting. 14. The dressing connector of claim 1, wherein the first fluid path comprises: a channel through the first connector; and a port exposing the channel to the exterior surface. 15. The dressing connector of claim 1, wherein the first connector comprises a ridge adapted to engage a downstream component. 16. The dressing connector of claim 1, further comprising an orientation recess adjacent to the second connector and the fourth connector. 17. The dressing connector of claim 1, further comprising a one-way valve in the second fluid path. 18. The dressing connector of claim 1, wherein the liquid barrier is disposed at least partially external to both the first connector and the exterior surface of the dressing connector. 19. A disposable dressing connector configured to couple a reusable container for collecting exudates to a dressing and to a reduced-pressure source, the dressing connector comprising: a fitting fluidly coupled to a first receptacle through an inline liquid barrier, the fitting configured to connect to the reduced-pressure source and the first receptacle configured to connect to the reusable container;a port fluidly coupled to a second receptacle, the port configured to connect to the dressing and the second receptacle configured to connect to the reusable container; anda tube fluidly coupled to the port;wherein the first receptacle and the second receptacle each comprises a cavity exposed to an exterior surface adapted to engage a container fitting. 20. The dressing connector of claim 19, wherein: the fitting comprises a male fitting and an annular ridge adapted to engage the downstream component; andeach cavity comprises an annular recess adapted to engage the container fitting. 21. The dressing connector of claim 1, wherein at least two of the first connector, the second connector, the third connector, or the fourth connector extend from the exterior surface of the dressing connector. 22. The dressing connector of claim 1, wherein: the dressing connector forms a single piece dressing connector removably coupled to a container with a container fitting coupled to at least one of the second connector or the fourth connector;the first connector, the second connector, the third connector, and the fourth connector are separate; andthe exterior surface of the single piece dressing connector is the exterior surface of the dressing connector.
