Abstract

An ostomy appliance or wound drainage device having a lower end with an adhesive composition thereon so that when the lower end is folded upon itself, the drainage opening is closed off, or, alternatively, the lower end is made of a material having intrinsic adhesive properties.

Claims

1. An ostomy appliance or wound drainage device comprising:

(a) a receptacle for storing waste material therein;

(b) a first opening in the receptacle for receiving waste material from a patient;

(c) a second opening in a lower end of the receptacle for releasing the waste material from the receptacle; and

(d) adhesive means on the lower end of the receptacle enabling the lower end of the receptacle to be folded and releasably adhered to itself to thereby close off said opening.

2. The device of claim 1 wherein the adhesive means comprises a washable adhesive.

3. The device of claim 1 wherein the adhesive means comprises the lower end of the receptacle being made of an adhesive material having intrinsic adhesive properties.

4. The device of claim 3 wherein the adhesive material is washable.

5. The device of claim 1 comprising a tube extending from the receptacle and in fluid communication therewith, said tube having an upper end in proximity to the receptacle and a lower end remote from the upper end with a central region therebetween, said tube further having an inner surface and an outer surface and an adhesive layer on at least one of said inner and outer surfaces whereby when the tube is bent in the central region the tube will remain in a folded-over condition sufficient to prevent the flow of fluid therethrough.

6. The device of claim 5 wherein the tube is made of an adhesive material having intrinsic adhesive properties.

7. The device of claim 5 wherein the adhesive layer is on the exterior surface of the tube, whereby the lower end of the tube releasably adheres to the upper end of the tube when the tube is in the folded-over condition.

8. The device of claim 5 wherein the adhesive layer is on the inner surface of the tube.

9. The device of claim 8 wherein the inner surface is comprised of opposed walls, said adhesive layer being on at least one of said walls.

10. The device of claim 9 wherein the adhesive layer covers the entire inner surface of the tube at least in the central region of the tube.

11. The device of claim 1 wherein the lower end of the receptacle comprises a first side and an opposed second side, one of said first and second sides having a first adhesive area surrounding said opening, and a second adhesive area adjacent said first adhesive area, wherein said first adhesive area is folded upon itself to form an adhesive seal with the second adhesive area to thereby close off said opening.

12. The device of claim 11 wherein at least a portion of the first adhesive area includes a relatively stiff supporting material.

13. The device of claim 1 wherein the adhesive means comprises an adhesive layer comprising at least two adhesive regions.

14. The device of claim 13 wherein the adhesive regions are separated from each other by a non-adhesive space.

15. The device of claim 13 wherein the adhesive regions are separated from each other by a scoreline.

16. The device of claim 11 further comprising a third adhesive area adjacent the second adhesive area, wherein the lower end of the receptacle is folded upon itself twice so that the third adhesive area is secured to the lower end of the receptacle.

17. The device of claim 16 wherein said receptacle further comprises a fourth adhesive area on the other of said sides, wherein the lower end of the receptacle is folded upon itself twice so that the third adhesive area is releasably secured to the fourth adhesive area and the first adhesive area is releasably secured to the second adhesive area to close off said opening.

18. The device of claim 11 wherein the second opening is at an endpoint of the receptacle, said lower end having a first adhesive area at the end point on a first side of the device and a second adhesive area on a second, opposed side of the device, wherein when the lower end of the receptacle is folded upon itself the first adhesive area is releasably secured to the second adhesive area to thereby close off the second opening.

19. The device of claim 11 further comprising a third adhesive area on a second, opposed side of the device wherein the lower end of the receptacle is folded upon itself twice so that the first adhesive area is releasably secured to the second adhesive area and the third adhesive area is secured to the lower end of the receptacle.

20. The device of claim 19 wherein the third adhesive area is an adhesive layer applied to the opposed side of the device.

21. The device of claim 19 wherein the third adhesive area comprises a region of the device made of a material having intrinsic adhesive properties.

22. The device of claim 1 wherein the lower end of the receptacle comprises a first side and an opposed second side, and a bottom end having a second opening therein between the first and second sides, one of said first and second sides having a first adhesive area and a second adhesive area adjacent thereto wherein said lower end is folded upon itself so that the first adhesive area forms an adhesive seal with the second adhesive area to thereby close off said second opening.

23. The device of claim 22 further comprising a third adhesive area adjacent the second adhesive area, wherein the lower end of the receptacle is folded upon itself twice so that the third adhesive area is secured to the lower end of the receptacle.

24. The device of claim 23 wherein said receptacle further comprises a fourth adhesive area on the other of said sides, wherein the lower end of the receptacle is folded upon itself twice so that the third adhesive area is releasably secured to the fourth adhesive area and the first adhesive area is releasably secured to the second adhesive area to close off said opening.

25. The device of claim 22 further comprising a third adhesive area on a second, opposed side of the device wherein the lower end of the receptacle is folded upon itself twice so that the first adhesive area is releasably secured to the second adhesive area and the third adhesive area is secured to the lower end of the receptacle.

26. The device of claim 22 wherein the second opening is at an endpoint of the receptacle, said lower end having a first adhesive area at the end point on a first side of the device and a second adhesive area on a second, opposed side of the device, wherein when the lower end of the receptacle is folded upon itself the first adhesive area is releasably secured to the second adhesive area to thereby close off the second opening.

27. The device of claim 1 wherein the adhesive means comprises at least one thermoplastic elastomer.

28. The device of claim 27 wherein the thermoplastic elastomer is a styrene copolymer or an acrylic resin.

29. The device of claim 28 wherein the styrene copolymer is selected from the group consisting of styrene-acrylonitrile-butadiene, styrene-butadiene-styrene, styrene-isoprene-styrene and styrene-ethylene/butylene-styrene.

30. The device of claim 29 wherein the styrene copolymer is a styrene-isoprene-styrene copolymer or a styrene-acrylonitrile-butadiene copolymer having a relatively high butadiene content.

31. The device of claim 28 wherein the styrene copolymer is combined with an oil to form a gel.

32. The device of claim 1 wherein the adhesive composition comprises an elastomeric composition having a modulus of elasticity sufficient to enable waste particles to be readily removed therefrom, and having an internal viscosity low enough to enable water-washing and high enough to provide tack.

33. The device of claim 32 wherein the modulus of elasticity is from about 1 to 100 psi and the internal viscosity is from about 1,000 to 20,000 poises.

34. The device of claim 33 wherein the adhesive composition further comprises a plasticizer.

35. The device of claim 33 wherein the adhesive composition is solid, hydrophobic and insoluble in water.

36. The device of claim 33 wherein the adhesive composition comprises high molecular weight polyvinyl chloride.

37. The device of claim 33 wherein the adhesive composition comprises a copolymer of vinyl chloride and vinyl acetate.
