Wound dressings and methods of use with integrated negative pressure source having a fluid ingress inhibition component

A wound dressing apparatus comprising:

• a wound dressing configured to be positioned over a wound site, the wound dressing comprising:
• a wound contact layer configured to be positioned in contact with a wound;
• a first area and a second area positioned adjacent to the first area, wherein the first area comprises an absorbent material and the second area is configured to receive a negative pressure source;
• and
• a cover layer configured to cover and form a seal over the wound contact layer, the first area, and the second area;
• a negative pressure source disposed on or positioned within the second area of the wound dressing, the negative pressure source comprising an inlet and an outlet and being operable to apply negative pressure to the wound site;
• and
• a porous polymer molded component comprising a port configured to receive at least a portion of the inlet and fitted to the inlet such that the porous polymer molded component is in fluid communication with the inlet and an interior of the wound dressing, the porous polymer molded component defining a plurality of flow paths between the interior of the wound dressing and the inlet such that occlusion of the inlet is inhibited, wherein the porous polymer molded component is in fluid communication with the absorbent material and configured to inhibit flow of wound exudate from the wound site into the inlet.
