Abstract

Described are improvements to the structure and functionality of a reduced pressure adapter used to connect a distribution manifold and a reduced pressure source instrumentation in a reduced pressure wound treatment (RPWT) system. The reduced pressure adapter reduces instances of unintentional liquid ingress into ancillary lumens of a reduced pressure delivery tube, while channeling the liquid to a primary lumen of the reduced pressure delivery tube.

Claims (43)

1. A reduced pressure adapter for connecting a reduced pressure source to a porous pad, the adapter comprising:

a conduit housing having a recessed region defining an entry surface;

a primary conduit through the conduit housing in fluid communication with a primary port on the entry surface;

at least one ancillary conduit through the conduit housing in fluid communication with an ancillary port on the entry surface;

channels positioned on the entry surface to direct liquid away from the ancillary port and into the primary port;

a base attached to the conduit housing such that an aperture of the base surrounds the recessed region; and

radial channels positioned on the base to direct liquid from a periphery of the base away from the ancillary conduit.

2. The adapter of claim 1 , wherein the conduit housing is rotatable about the base.

3. The adapter of claim 1 , further comprising:

an intermediate collection channel positioned on the base to direct liquid into the radial channels.

4. The adapter of claim 3 , wherein the conduit housing is rotatable about the base.

5. The adapter of claim 3 , wherein the channels comprise:

a linear channel section along approximately half of the entry surface; and

a radial channel section along approximately one-third of the entry surface.

6. The adapter of claim 3 , further comprising an oval reduced pressure delivery tube having a primary lumen fluidly connected to the primary conduit and an ancillary lumen fluidly connected to the ancillary conduit.

7. The adapter of claim 3 , further comprising a volatile organic compound sensitive strip mounted within the recessed region.

8. The adapter of claim 3 , wherein there are at least two ancillary conduits having diametrically opposite ancillary ports on the entry surface.

9. The adapter of claim 1 , wherein the channels comprise:

a linear channel section along approximately half of the entry surface; and

a radial channel section along approximately one-third of the entry surface.

10. The adapter of claim 1 , further comprising an oval reduced pressure delivery tube having a primary lumen fluidly connected to the primary conduit and an ancillary lumen fluidly connected to the ancillary conduit.

11. The adapter of claim 1 , further comprising a volatile organic compound sensitive strip mounted within the recessed region.

12. The adapter of claim 1 , wherein there are at least two ancillary conduits having diametrically opposite ancillary ports on the entry surface.

13. The adapter of claim 1 , further comprising a wall section supporting and surrounding the ancillary conduit, the wall section having an inside surface, an outside surface, and guide channels along the outside surface extending toward the primary port.

14. A reduced pressure adapter for connecting a reduced pressure source to a porous pad, the adapter comprising:

a conduit housing having a recessed region defining an entry surface;

a primary conduit through the conduit housing in fluid communication with a primary port on the entry surface;

at least one ancillary conduit through the conduit housing in fluid communication with an ancillary port on the entry surface;

channels positioned on the entry surface to direct liquid away from the ancillary port and into the primary port; and

a wall section supporting and surrounding the ancillary conduit, the wall section having an inside surface, an outside surface, and guide channels along the outside surface extending toward the primary port.

15. The adapter of claim 14 , further comprising:

a base attached to the conduit housing such that an aperture of the base surrounds the recessed region.

16. The adapter of claim 15 , wherein the conduit housing is rotatable about the base.

17. The adapter of claim 14 , further comprising:

a base attached to the conduit housing such that an aperture of the base surrounds the recessed region;

radial channels positioned on the base to direct liquid from a periphery of the base away from the ancillary conduit; and

an intermediate collection channel positioned on the base to direct liquid into the radial channels.

18. The adapter of claim 14 , wherein the channels comprise:

a linear channel section along approximately half of the entry surface; and

a radial channel section along approximately one-third of the entry surface.

19. The adapter of claim 14 , further comprising an oval reduced pressure delivery tube having a primary lumen fluidly connected to the primary conduit and an ancillary lumen fluidly connected to the ancillary conduit.

20. The adapter of claim 14 , further comprising a volatile organic compound sensitive strip mounted within the recessed region.

21. The adapter of claim 14 , wherein there are at least two ancillary conduits having diametrically opposite ancillary ports on the entry surface.
