An apparatus and system for fluidly connecting a reduced-pressure source to a dressing and a method for manufacturing and using the same include a base having an aperture and a wall having a peripheral portion coupled to the base. The wall may form a cavity in fluid communication with the aperture.
An apparatus and system for fluidly connecting a reduced-pressure source to a dressing and a method for manufacturing and using the same include a base having an aperture and a wall having a peripheral portion coupled to the base. The wall may form a cavity in fluid communication with the aperture. The apparatus also may include a conduit port fluidly coupled to the cavity and adapted to receive a conduit. The base may be adapted to couple to the dressing, and the wall may be adapted to collapse from a first position to a second position in response to a supply of reduced pressure from the reduced-pressure source.

1. An apparatus for fluidly connecting a reduced-pressure source to a dressing, the apparatus comprising: a base having an aperture;a wall having a peripheral portion coupled to the base to form a cavity, wherein the aperture is configured to provide fluid communication between the cavity and the dressing;a conduit port coupled to the wall and having a lumen fluidly coupled to the cavity; anda connector conduit having a first end adapted to be received in the lumen of the conduit port and a second end adapted to be mated with a tube for delivering reduced-pressure;wherein the base is adapted to couple to the dressing and the wall is adapted to collapse from a first position providing a first volumetric flow rate through the cavity at a flow velocity to a second position providing a second volumetric flow rate through the cavity while maintaining the flow velocity in response to a change in a supply of reduced pressure from the reduced-pressure source. 2. The apparatus of claim 1, wherein the wall has a thickness in a range of about 0.60 mm to about 2.00 mm. 3. The apparatus of claim 1, wherein the wall has a thickness of about 1.25 mm. 4. The apparatus of claim 1, wherein the wall comprises a polymer having a durometer in a range of about 25 Shore A to about 100 Shore A. 5. The apparatus of claim 1, wherein the wall comprises a polymer having a durometer of about 68 Shore A. 6. The apparatus of claim 1, wherein the wall comprises a polymer having a durometer in a range of about 25 Shore A to about 100 Shore A and a thickness in a range of about 0.60 mm to about 2.00 mm. 7. The apparatus of claim 1, wherein the wall comprises a polymer having a durometer and a thickness so that the wall is configured to collapse from the first position to the second position under reduced pressure. 8. The apparatus of claim 1, wherein the wall has a sloping profile when the wall is in the second position. 9. The apparatus of claim 1, wherein the cavity has a first volume when the wall is in the first position and a second volume when the wall is in the second position. 10. The apparatus of claim 1, wherein the cavity has a first volume when the wall is in the first position, a second volume when the wall is in the second position, and the first volume is greater than the second volume. 11. The apparatus of claim 1, wherein the cavity has a height from a top of the base to a top of the wall of about 3 mm. 12. The apparatus of claim 1, wherein the base has a diameter of about 34 mm. 13. The apparatus of claim 1, further comprising an adhesive coupled to the base and adapted to couple the base to the dressing, the adhesive adapted to create a fluid seal between the base and the dressing. 14. The apparatus of claim 1, wherein the wall and the base comprise polyvinyl chloride. 15. The apparatus of claim 1, wherein the connector conduit comprises a rigidity that is greater than a rigidity of the tube. 16. The apparatus of claim 1, wherein when the wall is in the second position, the wall extends horizontally from the base while sloping to the conduit port. 17. The apparatus of claim 1, wherein when the wall collapses from the first position to the second position, the wall is configured to change a cross-sectional area of a flow path through the cavity to maintain the flow velocity. 18. A method of manufacturing an apparatus for fluidly connecting a reduced-pressure source to a dressing, the method comprising: forming a base having an aperture;coupling a wall to the base adjacent to the aperture to form a cavity, wherein the aperture is configured to provide fluid communication between the cavity and the dressing; andfluidly coupling a conduit port to the wall and having a lumen fluidly coupled to the cavity;providing a connector conduit having a first end adapted to be received by the lumen of the conduit port and a second end adapted to mate with a tube for delivering reduced pressure;wherein the base is adapted to couple to the dressing and the wall is adapted to collapse from a first position providing a first volumetric flow rate through the cavity at a flow velocity to a second position providing a second volumetric flow rate through the cavity while maintaining the flow velocity in response to a change in a supply of reduced pressure from the reduced-pressure source. 19. The method of claim 18, wherein the method further comprises forming the wall with a thickness in a range of about 0.60 mm to about 2.00 mm. 20. The method of claim 18, wherein the method further comprises forming the wall with a thickness of about 1.25 mm. 21. The method of claim 18, wherein the method further comprises forming the wall from a polymer having a durometer in a range of about 25 Shore A to about 100 Shore A. 22. The method of claim 18, wherein the method further comprises forming the wall from a polymer having a durometer of about 68 Shore A. 23. The method of claim 18, wherein the method further comprises forming the wall from a polymer having a durometer in a range of about 25 Shore A to about 100 Shore A and a thickness in a range of about 0.60 mm to about 2.00 mm. 24. The method of claim 18, wherein the method further comprises forming the wall from a polymer having a durometer and a thickness so that the wall collapses from the first position to the second position under reduced pressure. 25. The method of claim 18, wherein coupling the wall having a peripheral portion to the base further comprises coupling the wall to the base so that the cavity has a height from a top of the base to a top of the wall of about 3 mm. 26. The method of claim 18, wherein forming the base further comprises forming the base with a diameter of about 34 mm. 27. The method of claim 18, wherein the method further comprises coupling an adhesive to the base and adapted to couple the base to the dressing, the adhesive further adapted to create a fluid seal between the base and the dressing. 28. The method of claim 18, wherein the method further comprises forming the wall and the base from polyvinyl chloride. 29.
