Abstract
Sealing device for sealing externally debouching, natural or artificial body canals of animals or human beings, the device enabling liquid tight sealing against the inner wall of the bowel system of the animal or human being, the device further being made from a resilient material. The device is soft and resilient and may thus not trigger the analreflex, but is still able to provide a fluid-tight seal.
Claims10
A sealing device for sealing a body canal of a user, the sealing device comprising:
- an elongated probe defining an irrigation lumen that is provided for administering irrigation liquid through the elongated probe to the body canal, the probe including a distal end portion providing a handle and a proximal end portion defining an opening communicating with the irrigation lumen;
- and
- a foam sealing element coupled with a central portion of the elongated probe such that the proximal end portion and the opening communicating with the irrigation lumen extend past a proximal end of the foam sealing element, the sealing device including a liquid impermeable member coupled to the foam sealing element to form a fluid barrier to preclude fluid from exiting the body canal when the device is positioned within the body canal, the foam sealing element including a convex outer surface and a concave inner surface that terminate at a collar formed at the proximal end of the foam sealing element, the concave inner surface closer to the proximal end portion of the probe than the convex outer surface is to the proximal end portion of the probe, the collar spaced a distance away from the probe and providing a curved lip that has a curvature different from the convex outer surface and the concave inner surface of the foam sealing element.
