Abstract

The hydrocolloid disk includes a polyethylene/PVDC film backing. The disk adheres to the acrylic adhesive layer of the collar over a large portion of the surface area of the disk. The collar is formed of a EVA/polyethylene perforated film on a polyethylene non-woven. In the one piece embodiment, the collar is secured directly to the pouch. In the two piece embodiment, the collar is secured directly to the coupling ring. Increased strength, better odor protection and improved breathability are achieved.

Claims

1. An ostomy device comprising:

a pouch with an inlet in a sidewall;

a faceplate proximate to said inlet attachable to said sidewall, said faceplate including a collar with a central opening adapted to align with said pouch inlet, said collar including a perforated EVA/polyethylene film between a non-woven polyethylene layer and an adhesive layer, and a hydrocolloid member having substantially an entire surface secured to said adhesive layer so as to securely join said hydrocolloid member to said collar; and

attaching means for attaching said faceplate to said pouch by welding said collar to said pouch.

2. The device of claim 1 wherein said hydrocolloid member includes a polyethylene/PVDC film.

3. The device of claim 2 wherein said polyethylene/PVDC film covers substantially the entire surface of said hydrocolloid member.

4. The device of claim 1 wherein said non-woven layer has a central opening smaller than said pouch inlet.

5. The device of claim 1 wherein said perforated EVA/polyethylene film covers substantially an entire surface of said non-woven layer.

6. The device of claim 1 wherein said adhesive layer is cast onto said EVA/polyethylene film.

7. The device of claim 1 wherein said EVA/polyethylene film is approximately 2 mils thick.

8. The device of claim 1 wherein said attaching means includes first and second coupling rings and wherein said collar is secured to said first coupling ring and said second coupling ring is secured to said pouch.

9. An ostomy device for receiving body waste comprising:

a pouch with an inlet in a sidewall for receiving the waste; and

a faceplate proximate to said inlet attachable to said sidewall, said faceplate including a collar with a central opening adapted to align said opening with said inlet and to attach to said pouch, and a hydrocolloid member having a backing of a polyethylene/PVDC film secured to said collar, said film protecting the hydrocolloid member from soiling by the body waste received in said pouch.

10. The device of claim 9 wherein said film is approximately 1 mil. thick.

11. The device of claim 9 wherein said polyethylene/PVDC film covers substantially the entire surface of said hydrocolloid member.

12. The device of claim 9 further comprising means for securing said collar to said pouch.

13. The device of claim 9 wherein said hydrocolloid member is attached to said collar over substantially an entire surface of said film.

14. The device of claim 12 wherein said means for securing includes first and second coupling rings and wherein said collar is secured to said first coupling ring and said second coupling ring is secured to said pouch.

15. The device of claim 9 wherein said collar includes a non-woven polyethylene member, a perforated EVA/polyethylene film and an adhesive layer.

16. The device of claim 15 wherein said non-woven member has a central opening smaller than said pouch inlet.

17. The device of claim 15 wherein said perforated EVA/polyethylene film covers substantially an entire surface of said non-woven member.

18. The device of claim 15 wherein said adhesive layer is cast onto said EVA/polethylene film.

19. The device of claim 15 wherein said EVA/polyethylene film is approximately 2 mils. thick.

20. An ostomy device comprising:

a pouch with an inlet in a sidewall for receiving waste;

an adhesive non-woven collar having a central opening aligned with said pouch inlet;

securing means for securing said collar directly to said sidewall of said pouch; and

a hydrocolloid member secured to said collar over substantially the entire surface of said hydrocolloid member, wherein said collar comprises a perforated EVA/polyethylene film between a non-woven polyethylene member and an adhesive layer.

21. The device of claim 20 wherein said hydrocolloid member comprises a polyethylene/PVDC film.

22. The device of claim 21 wherein said polyethylene/PVDC film covers substantially an entire surface of said hydrocolloid member.

23. The device of claim 20 wherein said non-woven member has a central opening smaller than said pouch inlet.

24. The device of claim 20 wherein said perforated EVA/polyethylene film covers substantially an entire surface of said non-woven member.

25. The device of claim 20 wherein said adhesive layer is cast onto said EVA/polyethylene film.
