A low-profile ostomy appliance, and a method for producing it, in which a microporous adhesive patch extends about a soft, pliable, barrier ring with the concentric distal (outwardly-facing) surfaces of both the patch and ring being adhesively secured to a connecting ring of soft, flexible, closed-cell, thermoplastic foam, the connecting ring in turn being heat sealed to the wall of a collection pouch about its inlet opening.

An ostomy appliance comprising an ostomy pouch equipped with a faceplate for adhesive attachment to a patient; said pouch being formed of thermoplastic film and having one wall provided with a stoma opening therein; said faceplate comprising a skin barrier ring, a microporous patch, and a connecting ring joining together said skin barrier ring, microporous patch, and pouch; said skin barrier ring being formed of a soft, pliable, water-absorbing composition having both dry tack and wet tack characteristics; said skin barrier ring also having a proximal face for sealingly engaging the peristomal skin surfaces of a patient and a generally planar distal face; said microporous patch being formed of thin, microporous sheet material having gas and water vapor transmissibility and having planar proximal and distal surfaces; said proximal surface being coated with a pressure-sensitive adhesive and said distal surface being generally coplanar with said distal face of said skin barrier ring; said microporous patch having an opening receiving said skin barrier ring; said connecting ring being formed of soft, flexible, liquid and gas impermeable, closed-cell thermoplastic foam and having an outside diameter substantially greater than said opening of said microporous patch; said connecting ring covering, and being adhesively secured to, the distal face of said skin barrier ring and a concentric portion of the distal surface of said microporous patch about said skin barrier ring; said connecting ring having a distal surface heat sealed to said wall of said pouch in an annular zone about said stoma opening.
