System for administering reduced pressure treatment having a manifold with a primary flow passage and a blockage prevention member
First Claim
1. A reduced pressure delivery system for applying a reduced pressure tissue treatment to a tissue site comprising:
- a primary manifold having a wall surrounding a primary flow passage and adapted to be placed in proximity to the tissue site, the wall including an inner surface having a plurality of projections extending from at least a portion of the inner surface and into the primary flow passage, the wall further including a plurality of apertures through the wall and communicating with the primary flow passage;
a first conduit fluidly connected to the primary flow passage to deliver reduced pressure through the primary flow passage and the plurality of apertures; and
a second conduit having at least one outlet in proximity to the primary flow passage or the at least one outlet of the first conduit to purge blockages at or near the at least one outlet of the first conduit.

Abstract
A reduced pressure delivery system is provided and includes a primary manifold, a blockage prevention member, and first and second conduits in fluid communication with the primary manifold. The primary manifold includes a wall surrounding a primary flow passage and is adapted to be placed in proximity to a tissue site. The blockage prevention member is positioned within the primary flow passage. A plurality of apertures is disposed in the wall to communicate with the primary flow passage. The first conduit is fluidly connected to the primary flow passage to deliver reduced pressure through the primary flow passage and the plurality of apertures. The second conduit includes an outlet proximate the primary flow passage or an outlet of the first conduit to purge the primary flow passage or first conduit to prevent blockages.
