Abstract
A faceplate assembly for an ostomy pouch system including an invertible stoma collar is provided. The invertible stoma collar protrudes toward a stoma and defines an inlet opening. The invertible stoma collar is formed from a flexible material having an elastic memory, such that the stoma collar hugs the stoma as the stoma is received through the inlet opening, and becomes inverted. The inverted stoma collar has a tendency to regain its original shape, and thus, applies sufficient pressure to seal around the stoma without strangulating the stoma.
