Abstract

A stoma pad configured to cooperate with a fluid handing tube comprises a flexible, resilient, soft annular pad having a generally flat bottom surface and a convex annular wall extending upwardly from the bottom surface, and a circular hole extending through the center of the annular wall and the bottom surface. A stoma pad assembly comprises the stoma pad and a retention, support or holding device for securing the stoma pad on a patient.

Claims

1. A stoma pad configured to cooperate with a fluid handling tube inserted into a body wound to seal the body wound, the stoma pad comprising:

a flexible annular pad having a generally flat bottom surface;

a thin, flexible cover, the cover forming a convex annular wall extending upwardly from the bottom surface, the cover comprised of a first material;

a pliant and flexible second material encased in the cover;

a circular hole extending through the center of the convex annular wall and the bottom surface, wherein the circular hole allows the stoma pad to be secured on the fluid handling tube, wherein a generally circular inside wall surface of the convex annular wall extends upwardly from the bottom surface, defines a circular hole, and is tapered toward the convex annular wall; and

a slit extending through said convex annular wall and bottom surface, wherein said slit is shaped to form a tongue on one side thereof and a recess on the opposite side thereof for receiving said tongue and forming a fluid seal therebetween.

2. The stoma pad of claim 1 wherein said annular wall comprises the generally circular inside wall surface and an opposite outside wall surface extending upwardly from said bottom surface, a generally convex connecting surface extending between said inside wall surface and said outside wall surface.

3. The stoma pad of claim 2 wherein the distance across said convex connecting surface is greater than the height of either said inside wall surface or said outside wall surface.

4. The stoma pad of claim 2 wherein the thickness of said annular wall is greater than the height of said annular wall.

5. The stoma pad of claim 2 comprising a circular channel extending circumferentially around said outside wall surface.

6. The stoma pad of claim 1 comprising a soft, flexible, resilient plastic material.

7. The stoma pad of claim 1 comprising polyurethane and/or silicon rubber.

8. The stoma pad of claim 1 comprising silicon gel coated with polyurethane.

9. A stoma pad assembly comprising a stoma pad of claim 1 and a stoma pad holding device comprising a flexible bandage secured to the stoma pad.

10. The stoma pad assembly of claim 9 wherein said flexible bandage includes a contact adhesive surface for securing said assembly on a patient.

11. The stoma pad assembly comprising a stoma pad of claim 1 and a stoma pad retention device comprising a generally flat surface for being urged against said generally flat bottom surface of said stoma pad and a hole therethrough aligned with said circular hole through said stoma pad.

12. The stoma pad assembly of claim 11 wherein said retention device comprises a flexible bandage and wherein said generally flat surface thereof comprises a contact adhesive.

13. The stoma pad assembly of claim 11 wherein said generally flat bottom surface of said stoma pad comprises one or more indentations and said generally flat surface of said retention device comprises one or more protuberances for being received in said one or more indentations, respectively.

14. The stoma pad assembly of claim 11 wherein said generally flat surface of said retention device comprises one or more indentations and said generally flat bottom surface of said stoma pad comprises one or more protuberances for being received in said one or more indentations.

15. The stoma pad assembly of claim 9, comprising a stoma pad retention device having a substantially circular hole therein, the circular edge of said hole received in a circular channel of said stoma pad.

16. The stoma pad assembly of claim 11 including a fluid handling tube extending through said stoma pad hole and said retention device hole.

17. The stoma pad assembly of claim 12 including a fluid handling tube extending through said stoma pad hole and said retention device hole.

18. The stoma pad assembly of claim 11 wherein said stoma pad is secured to said retention device with adhesive.

19. A stoma pad configured to cooperate with a fluid handling tube inserted into a body wound to seal the body wound, the stoma pad comprising:

a flexible annular pad having a generally flat bottom surface;

a thin flexible cover forming a convex annular wall extending upwardly from the bottom surface, the cover comprised of a first material;

a pliant and flexible second material encased in the cover;

a circular hole extending through the center of the annular wall and the bottom surface, wherein the circular hole allows the stoma pad to be secured on the fluid handling tube; and

a slit extending through said convex annular wall and bottom surface, wherein said slit is shaped to form a tongue on one side thereof and a recess on the opposite side thereof for receiving said tongue and forming a fluid seal therebetween.
