Abstract

An ostomy device (1) has an implant (10) arranged, in use, to be located inside the body of person near the site of a stoma (S). A discharge device (20) is arranged, in use, to provide means for intestinal waste to exit to the exterior of the body of the person. In addition, there is means, in use, to be operatively associated with the implant (10) and removably locate the discharge device (20) at the site of the stoma (S). The discharge device (20) is retained at the site of the stoma (S) by magnetic attraction between the implant (10) and the discharge device (20).

5. An ostomy device according to claim 4, wherein the discharge device comprises a first portion and a second portion detachably connected together, the first portion having the tubular member and the second portion having the valve.

6. An ostomy device according to claim 1, wherein the valve comprises a housing,

a sealing member mounted in the housing and movable from a first position, in which the valve is in a closed condition, to a second position in which the valve is in an open condition, and

handle operable to move the sealing member between the first and second positions to open and close the valve,

wherein the handle is operable to open and close the valve, in use, to control the discharge of the fluid and materials to the exterior of the body of the person.

7. An ostomy device according to claim 6, wherein the valve further comprises a valve seat and the sealing member has a substantially convex surface and a substantially concave surface on respective opposed faces thereof, wherein the convex surface is in contact with the valve seat in the closed condition of the valve and the convex surface is positioned adjacent an inner surface of the housing and is no longer in contact with the valve seat in the open condition of the valve, and the convex surface is provided at the upstream side of the direction of fluid flow through the discharge means.

8. An ostomy device according to claim 6, wherein the housing is provided with a neck having a diameter less than the diameter of the portion of the housing that accommodates the sealing member and the valve seat is provided between the neck and the portion of the housing that accommodates the sealing member.

9. An ostomy device according to claim 1, further comprising a pressure relief valve provided to release gas pressure at the upstream side of the direction of fluid flow through the discharge means, as required, when the valve means is in the closed condition.

10. An ostomy device according to claim 6, further comprising a pressure relief valve provided to release gas pressure at the upstream side of the direction of fluid flow through the discharge means, as required, when the valve means is in the closed condition and the pressure relief valve comprises a tube and a closable hole is provided in the sealing member such that a tip of the tube is moveable through the closable hole in the sealing member to allow gas to exit through the tube and the tube is moveable to retract the tip and close the closable hole.

11. An ostomy device according to claim 10, wherein the pressure relief valve further comprises a spring to bias the tube such that the tip is retracted in the closed condition of the pressure relief valve.

12. An ostomy device according to claim 1, wherein a removable cap is provided to close an end of the housing and the removable cap accommodates the pressure relief valve.

13. An ostomy device according to claim 5, further comprising securing means, in use, to secure the discharge device at the site of the stoma and the securing means comprises case means arranged, in use, to be provided between the retention means and the site of the stoma substantially cover the second portion of the discharge means.

14. An ostomy device according to claim 13, characterised in that the retention means is arranged to be removably mounted to the case means.

15. A fluid flow control valve for a medical device comprising
