Claims
- 1. A thin film device for medical applications, comprising:
- a) an occlusive layer comprising a hydrocolloid, having a perimeter and an edge portion about at least a portion of the perimeter of the occlusive layer and a body portion, said body portion being spaced apart from the skin of the user;
- b) a non-continuous, hydrocolloid-containing polymeric support layer in the form of a web, net or perforated film overlying the edge portion of the occlusive layer, said polymeric support layer being made of a material and constructed so as to permit the rapid uptake of body fluids emanating from a wound;
- c) an absorbent region comprising a multi-layer laminate having at least two layers, positioned between the occlusive layer and the support layer; and
- d) a layer attached to the polymeric support layer having an adhesive thereon for attaching to the skin of the user.
- 2. The thin film device of claim 1 wherein the edge portion extends about the entire perimeter of the thin film dressing.
- 3. The thin film device of claim 1 wherein the occlusive layer is relatively impervious to moisture.
- 4. The thin film device of claim 1 wherein the occlusive layer has a moisture vapor transmission rate of from about 450 to 3000 g/m.sup.2 /24 hours at 100.degree. F. and 90% relative humidity.
- 5. The thin film device of claim 1 wherein the occlusive layer is made from a material selected from the group consisting of polyolefins, polyurethanes, and vinylidene chloride copolymers.
- 6. The thin film device of claim 1 wherein the polymeric support layer contains more than one hydrocolloid.
- 7. The thin film device of claim 1 wherein the hydrocolloid is incorporated into the polymeric support layer.
- 8. The thin film device of claim 1 wherein the hydrocolloid is coated onto the polymeric support layer.
- 9. The thin film device of claim 1 wherein said absorbent region is a composite of absorbent materials.
- 10. The thin film device of claim 1 wherein said absorbent region comprises at least one hydrocolloid and at least one superabsorbent.
- 11. The thin film device of claim 10 wherein said at least one hydrocolloid and at least one superabsorbent is incorporated into polymeric fibers.
- 12. The thin film device of claim 10 wherein said absorbent region comprises at least one hydrocolloid and at least one superabsorbent incorporated into a polymeric fabric.
- 13. The thin film device of claim 10 wherein said absorbent region comprises at least one hydrocolloid and at least one superabsorbent incorporated into a polymeric structure.
- 14. The thin film device of claim 10 wherein said hydrocolloid and superabsorbent are sandwiched between layers of polymeric fibers.
- 15. The thin film device of claim 10 wherein said hydrocolloid and superabsorbent are sandwiched between layers of polymeric fabric.
- 16. The thin film device of claim 12 wherein said hydrocolloid and superabsorbent are sandwiched between layers of polymeric foam.
- 17. The thin film device of claim 1 wherein said polymeric support layer is adhered to said occlusive layer by an adhesive.
- 18. The thin film device of claim 1 wherein said polymeric support layer is adhered to said occlusive layer by heat.
- 19. The thin film device of claim 1 wherein said polymeric support layer is adhered to said occlusive layer by ultrasonic bonding.
- 20. The thin film device of claim 1 in the form of a wound dressing.
- 21. The thin film device of claim 1 in the form of a skin-contacting baseplate for an ostomy appliance.
- 22. The thin film device in the form of a wound dressing of claim 20 wherein
- the polymeric support layer comprises a blend of hydrocolloid and a polymeric material having a melting temperature of less than about 105.degree. C.
- 23. The wound dressing of claim 22 wherein said polymeric material is an ethylene vinyl acetate.
- 24. The wound dressing of claim 23 wherein said ethylene vinyl acetate has a vinyl acetate content of from about 15% to about 28%.
- 25. The wound dressing of claim 24 wherein said ethylene vinyl acetate has a vinyl content of about 18%.
- 26. The wound dressing of claim 25 wherein said polymeric material and hydrocolloid have been extruded together.
- 27. The wound dressing of claim 24 wherein said polymeric support layer is biaxially oriented.
