Abstract

A closure appliance for use in surgical ostomy comprising an upper member and a lower member. The upper member contains a cavity for receiving a closure. The closure is provided with filtration and absorbent materials. The lower member contains a plurality of tubular passageways which communicate with the cavity in the upper portion. Magnetic members surround the tubular passageways for magnetically securing the device to a magnetized annulus which has been implanted in the surrounding skin of the stoma. The closure appliance is utilized to tightly fit within the stoma and to selectively permit the evacuation of fluids from the interior of the stoma.

Claims

1. A closure appliance for use in cases involving surgical ostomy which comprises

a body formed by an upper member adapted to be disposed on the outside of the stoma and a lower member adapted to extend inside the stoma, said upper and lower members being securely joined together by an intermediate area of reduced cross section forming a flexible, elastic joint which allows relative angular movement between said members in a rotula manner,

a first magnetic element incorporated in the wall of said lower member, in such a manner as to be capable of interacting with a second magnetic element surrounding the stoma so as to cause the lower member wall to form a seal with the stoma wall, and

at least one passageway extending through said body and providing communication between the upper member and the bottom of the lower member, said upper member containing a cavity which communicates with the interior of the stoma through said passageway extending through the lower member of the appliance.

2. The closure appliance of claim 1 wherein a plurality of tubular passageways extend axially from the cavity in the upper member to the bottom of the lower member.

3. The closure appliance of claim 1 wherein the flexible elastic joint is in the form of a flexible elastic stem.

4. The closure appliance of claim 1 wherein the cavity in the upper member is provided with a detachable cover, said cavity containing means for filtering and absorbing the emanations proceeding from the stoma.

5. The closure appliance of claim 1 wherein the first magnetic element surrounds said passageway.

6. The closure appliance of claim 2 wherein a stem of elastic material is disposed within the first magnetic element which surrounds said passageways, said passageways extending through said elastic material from the cavity in the upper member to the bottom of the lower member for the evacuation of fluids from the interior of the stoma to the cavity in the upper member.

7. The closure appliance of claim 1 wherein the cavity in the upper member contains a component which conforms thereto, thereby providing a greater rigidity to said upper member, said component containing an orifice which is coincident with the position of the passageway to permit the evacuation of fluids from the interior of the stoma.

8. The closure appliance of claim 4 wherein the detachable cover contains said filtering and absorbing means.

9. The closure appliance of claim 8 wherein the detachable cover contains at least one hole so that gases emanating from the stoma can flow through the hole to the outside of the device.

10. The closure appliance of claim 9 wherein the detachable cover is in the form of a disk and the filtering means and absorbing means disposed therein define a cap chamber which communicates with the fluids emanating from inside of the stoma.

11. The closure appliance of claim 10 wherein the filter material covers the inside of the cap and the absorbent material laterally surrounds the cap chamber, said cap chamber thereby being defined laterally by the walls of the absorbent material and at the top by the filter material.

12. The closure appliance of claim 10 wherein the detachable cover is provided with means for facilitating its attachment to the closure appliance.

13. The closure appliance of claim 10 wherein the detachable cover is provided with a transparent zone for viewing changes of color in the absorbent material arising from changes in the level of humidity in the absorbent material.

14. The closure appliance of claim 4 wherein the detachable cover is free of holes and thus provides a tight seal construction.

15. The closure appliance of claim 4 wherein the detachable cover is fitted with a bag for the collection of fluids.

16. The closure appliance of claim 1 wherein said intermediate area of reduced cross-section is substantially perpendicular to the longitudinal axis of the closure appliance, in its relaxed state.

17. A closure appliance for use in cases involving surgical ostomy which comprises

a magnetic ring adapted to be implanted in a patient in the surrounding skin of a stoma,

a body formed by an upper member adapted to be disposed on the outside of the stoma and a lower member adapted to extend inside the stoma, said upper and lower members being securely joined together by an intermediate area of reduced cross section forming a flexible, elastic joint which allows relative angular movement between said two members in a rotula manner,

a magnetic element incorporated in the wall of said lower member, which interacts with said magnetic ring to cause a seal to form between the stoma and the lower member wall and

at least one passageway extending through said body and providing communication between the upper member and the bottom of the lower member, said upper member containing a cavity which communicates with the interior of the stoma through said passageway extending through the lower member of the appliance, whereby the lower member of the body is tightly secured within the stoma to selectively permit the evacuation of fluids from the interior of the stoma.
