a foam disc having first and second faces and having pressure-sensitive adhesive on each of said faces, the second face of said foam disc being adhered to the cloth-like disc and the convex central body portion of the plastic disc;

a first adhesive skin barrier disc having an outer diameter substantially corresponding to the outer diameter of said foam disc, said first skin barrier disc being adhered to the first face of said foam disc; and

a second adhesive skin barrier disc being adhered to the first face of said first skin barrier disc, said second skin barrier disc having an inner diameter that is stretchable from a smallest diameter that is a point distal from an inner diameter of said plastic disc to a largest diameter that substantially corresponds to the inner diameter of said plastic disc.

7. A mounting disc as in claim 1 , including a removable protective film covering the first face of said second skin barrier disc and a removable protective paper covering the first face of said cloth-like disc.

8. A mounting disc as in claim 7 including diametrically opposed and radially extending mounting loops at a periphery of said flexible plastic disc, said mounting loops do not substantially extend beyond the diameter of the cloth-like disc.

9. A ostomy device comprising:

a mounting disc and an ostomy pouch;

said mounting disc comprising a flexible plastic disc having a convex central body portion and a surrounding annular rim,

a foam disc having first and second faces and having pressure-sensitive adhesive on each of said faces, the second face of said foam disc being adhered to the convex central body portion and the surrounding annular rim of the plastic disc,

a first adhesive skin barrier disc having an outer diameter substantially corresponding to the outer diameter of said foam disc, said first skin barrier disc being adhered to the first face of said foam disc, and

a second adhesive skin barrier disc being adhered to the first face of said first skin barrier disc, said second skin barrier disc having an inner diameter that is stretchable from a smallest diameter that is a point distal from an inner diameter of said plastic disc to a largest diameter that is substantially corresponding to the inner diameter of said plastic disc; and

said ostomy pouch comprising proximal and distal sheets of plastic film sealed at their peripheries, said proximal sheet having a stoma inlet portal therein, said inlet portal having a diameter substantially corresponding to an inside diameter of the annular rim of said flexible plastic disc, said annular rim being sealed to said proximal sheet about a zone surrounding said portal.

10. A mounting disc as in claim 9 including diametrically opposed and radially extending mounting loops at a periphery of said flexible plastic disc.

11. A mounting disc as in claim 10 including a cloth-like disc having first and second faces and having adhesive on said first face, said cloth-like disc having an outer diameter greater than an outer diameter of said flexible plastic disc, the second face of said cloth-like disc being adhered to the surrounding annular rim of the plastic disc and the first face of said cloth-like disc being adhered to the foam disc.

12. A mounting disc as in claim 11 , wherein said mounting loops do not substantially extend beyond the diameter of the cloth-like disc.

13. A mounting disc as in claim 9 , including a removable protective film covering an exposed first face of said first skin barrier disc and the first face of said second skin barrier disc.

14. A mounting disc for an ostomy pouch comprising a flexible plastic disc having a convex central body portion and a surrounding annular rim, a first foam disc having first and second faces and having pressure-sensitive adhesive on each of said faces, said first foam disc having an outer diameter substantially corresponding to the outer diameter of said flexible plastic disc, the second face of said first foam disc being adhered to the convex central body portion and the surrounding annular rim of the plastic disc, a second foam disc having first and second faces and having pressure-sensitive adhesive on said first face of said second foam disc, said second foam disc having an outer diameter greater than the outer diameter of said flexible plastic disc, the second face of said second foam disc being adhered to the first face of said first disc, an adhesive skin barrier disc having an outer diameter substantially corresponding to the outer diameter of said second foam disc, said skin barrier disc being adhered to the first face of said second foam disc, said skin barrier disc having an inner diameter that is stretchable from a smallest diameter that is a point distal from an inner diameter of said plastic disc to diameter that substantially corresponds to the inner diameter of said plastic disc.

15. A mounting disc according to claim 14 including diametrically opposed and radially extending mounting loops at a periphery of said flexible plastic disc.

16. A mounting disc according to claim 15 wherein said mounting loops do not extend beyond the diameter of the skin barrier disc and the second foam disc.

17. A mounting disc according to claim 14 wherein the skin barrier disc is an elastomer hydrocolloid mixture.
