ABSTRACT:
The fecal collector that includes a bag of elastomeric heat-sealable film having an opening for receiving fecal discharge and a thin attachment patch having a central opening in register with the opening of the bag. The patch includes a skin barrier layer of rubbery pressure-sensitive adhesive having hydrocolloid particles dispersed therein and having a backing layer secured to one side of the skin barrier layer. The backing layer is formed of stretchable and contractable heat-sealable material and is joined to the bag along a narrow annular heat seal line immediately surrounding the openings of the bag and patch. Because of the elastic properties of the materials, the openings may readily expand and contract to accommodate anatomical changes commonly occuring during defecation, thereby preventing disruption of the adhesive attachment between the patch and the patient. The backing layer of the patch is provided with a tab portion extending outwardly beyond the skin barrier layer to facilitate later removal of the patch from the patient's skin, such tab portion overlying a similar tab portion extending from a removable release sheet that protects the opposite side of the skin barrier layer prior to adhesive attachment of the patch to the patient. The patch also includes a removable perineal section that may be cut from the patch as delineated by guidelines imprinted on the release sheet.
