Abstract: An ostomy barrier seal comprising an open-ended conical base 1; and a flange portion 2 extending radially from the base; wherein the conical base 1 has a top opening 3 and a bottom opening 5 for receiving a stoma of a user and the top opening diameter 9 is smaller than the bottom opening diameter 11; such that the stoma of the user fits through the bottom opening and the top opening expands to snuggly fit around and seal along the stoma wall; a related ostomy appliance incorporating the barrier seal; and a related method using the barrier seal to reduce the incidence of waste leakage in an ostomy patients.

Abstract: A pump assembly for dispensing fluent material from within a container includes a tank and a piston defining therebetween a pump chamber and movable relative to each other to pump fluid from the container into and out of the pump chamber. A poppet interposed between the tank and the piston extends at one end thereof into the inlet conduit for the pump chamber and at the opposite end into the exhaust conduit. When the tank and piston are moving relative to each other to draw fluid from the container into the pump chamber, the end of the poppet extending to within the exhaust conduit engages against a valve seat defined in the exhaust conduit to close the exhaust conduit. The other end of the poppet extending to within the inlet conduit is frictionally engaged within the inlet conduit and the drag forces thus effected upon this end of the poppet operate to enhance the sealing effect of the opposite end of the poppet to close the exhaust conduit thereby permitting fluid to be drawn into the pump chamber.
