Abstract
Abstract Pouch type wound care and drainage system wherein the pouch includes a bottom wall secured to an adhesive layer which can be cut to fit around the wound or surgical opening, gusseted side walls, and a top wall provided with one or more access openings. Means are provided for securing an irrigation port and a catheter access port to these top wall openings. The bottom wall extends beyond the adhesive layer and is provided with a large exit port oriented in such a manner that gravity will drain wound exudate from the pouch. This exit port is also large enough to accommodate the average size hand to aid in locating the pouch on the body and permit access to the wound site without removing the pouch from the body.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
86 words
A wound care and drainage system comprising a pouch having a bottom wall, top wall, and gusseted side walls, said pouch walls formed from a transparent, moisture proof, odor proof, polymeric film material, a portion of said pouch bottom wall secured to an adhesive layer with the remainder of said pouch bottom wall extending beyond said adhesive layer, an aperture in said extended pouch bottom wall, and means encircling said bottom wall aperture whereby a cap can be detachably secured to seal said bottom wall aperture.
Claim 2
Dependent Claim
86 words
A wound care and drainage system comprising a pouch having a bottom wall, top wall, and gusseted side walls, said pouch walls formed from a transparent, moisture proof, odor proof, polymeric film material, a portion of said pouch bottom wall secured to an adhesive layer with the remainder of said pouch bottom wall extending beyond said adhesive layer, an aperture in said extended pouch bottom wall, and means encircling said bottom wall aperture whereby a cap can be detachably secured to seal said bottom wall aperture.
Claim 3
Dependent Claim
39 words
A wound care and drainage system as in Claim 1 wherein said pouch top wall includes one or more apertures and means encircling said top wall apertures whereby caps can be detachably secured to seal said top wall apertures.
Claim 4
Dependent Claim
86 words
A wound care and drainage system as in Claim 2 wherein flanges of polymeric material are sealed to said bottom pouch wall and said top pouch wall around said bottom wall aperture and said top wall apertures, said flanges have an outwardly and perpendicularly extending coupling rib shaped member, and caps of polymeric material are attached by a hinge to each of said flanges, said caps having a channel shaped coupling member dimensioned to snap - over the coupling rib shaped member of the corresponding flange.
Claim 5
Dependent Claim
36 words
-4. A wound care and drainage system as in Claim 3 wherein said coupling rib shaped members have a thin, resilient, deflectible seal strip which deforms into a tight fit within said channel shaped coupling members.
Claim 6
Dependent Claim
22 words
A wound care and drainage system as in Claim 4 wherein said seal strips extend inwardly from said coupling rib shaped members.
Claim 7
Dependent Claim
22 words
A wound care and drainage system as in Claim 4 wherein said seal strips extend outwardly from said coupling rib shaped members.
Claim 8
Dependent Claim
26 words
A wound care and drainage system as in Claim 3 wherein a catheter retaining means is detachably secured to one of said pouch top wall apertures.
Claim 9
Dependent Claim
116 words
A wound care and drainage system as in Claim 7 wherein said catheter retaining means comprises a flat envelope of polymeric material sealed along three edges and having an aperture in one wall of said envelope, a channel shaped coupling member secured to said envelope around said aperture, said channel shaped coupling member dimensioned to snap over the coupling rib shaped member projecting from the flange secured around said pouch top wall aperture, and strips of polymeric foam material secured to the surfaces of said envelope near the open end of said envelope, said strips of foam coated with an adhesive material so that the foam strips can be pressed into tight contact with a catheter.
Claim 10
Dependent Claim
26 words
A wound care and drainage system as in Claim 3 wherein a wound irrigation means is detachably secured to one of said pouch top wall apertures.
Claim 11
Dependent Claim
