Abstract
In accordance with the present invention a novel wound dressing providing superior absorption and preventing leakage is disclosed. The present dressing comprises a hydrocolloid-containing polymeric support layer either continuous or non-continuous and an occlusive backing layer overlying the support. In a preferred embodiment the present dressing further includes an adhesive on a skin-contacting surface of the support and an absorbent region interposed between the support and the backing layer.
Claims26
A skin-contacting medical device comprising a non-continuous, hydrocolloid-containing skin facing polymeric support layer allowing for the rapid uptake of wound or body fluids, an occlusive backing layer overlying said polymeric support layer, and an absorbent layer between and non-removably connected to said polymeric support layer and said occlusive layer.
A wound dressing comprising:
- a) an occlusive layer of a polyurethane film;
- b) an absorbent region of:
- I) a polymeric web;
- II) a first layer of polypropylene fibers;
- III) a mixture of hydrocolloids and superabsorbents;
- and
- IV) a second layer of polypropylene fibers;
- c) a polymeric support layer allowing for the rapid uptake of wound or body fluids;
- and
- d) a hydrocolloid-containing adhesive layer.
