A rubberized sealing ring (22) has a flat smooth broad bottom sealing surface for sealing with and spreading the pressure over an area of the rectal mucosal tissue. A peaked top surface has a wide inwardly sloping face for funneling the fecal matter into a tapering funnel shaped neck (28). The sealing ring (22) compresses together in a linear shape for anal insertion and expends resiliently into a sealing ring (22) inside the patient past the interior anal sphincter. An external receptacle (30) connects to the neck (28) for collecting excretions. A gas release valve (29) is built into the top of the receptacle (30). Reinforcement on two sides of the sealing ring (22) facilitates collapse of the sealing ring (22) on the non-reinforced sides into a linear configuration by pulling on the neck (28) for easy removal of the device from the patient.
