Abstract
A negative pressure wound therapy dressing and drainage apparatus includes: (1) a semi-permeable cover sheet adapted to cover a patient's wound; (2) a porous dressing adapted to be positioned between the semi-permeable cover sheet and the patient's wound; and (3) a drainage connection configured to be attached to the semi-permeable cover sheet including (a) a novel suction port in fluid communication with the porous dressing positioned within the interior of the semi-permeable cover sheet when attached to the semi-permeable cover sheet, and (b) tubing coupled to the suction port at one end and adapted to be connected to a suction source at an opposing end. The novel suction port includes a suction port inlet adapted to be secured to the semi-permeable cover sheet, a suction port outlet secured to the tubing and oriented generally perpendicular to the suction port inlet and a conduit extending between the suction port inlet and suction port outlet, where the inner surface of the conduit has smooth transition from the suction port inlet to the suction port outlet.
