Valve and methods for urinary control

摘要

The apparatus for closing a body orifice. The apparatus includes a valve having a flexible bulbous tube with an inlet and outlet. A passage in the bulbous tube extends from the inlet along an axis. A wall of the tube is between the inlet and the outlet and has a barrel shape tapered to the inlet and outlet and wider therebetween. The wall extends between an inside and an outside. A hinge is located in the wall where the barrel shape wall defines the passage, and the hinge is an area of preferential bending so the bulbous tube is either a barrel or flipped with the outlet folded about the hinge into the passage. The outlet has holes through the wall. A seat within the bulbous tube is on the inside of the wall in the passage to engage the outlet when the tube is flipped into the passage by bending the hinge acutely as the outlet is moved along the axis to the inlet and against the seat.
