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.
Claims21
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.
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.
