Abstract

A wound management dressing device. A foamed polyurethane pad of a selected size and having a hydrophilic side for contact with a wound and a hydrophobic side for facing away from the wound is positioned on a porous non-woven fibrous sheet of a larger selected size and having an adhesive on the side contacting the hydrophobic side of said pad so that the device presents the hydrophilic side and the adhesive for use in contact with the wound. A non-sticking removable cover is placed over the adhesive side of the sheet to prevent early exposure of the pad and the adhesive.

Claims

1. A wound management device, comprising:

a polyurethane foamed pad of a selected size and having a hydrophilic side for contact with a patient and a hydrophobic side for facing away from the patient;

a porous, non-woven fibrous sheet of a larger selected size and having an adhesive on one side, said hydrophobic side of said pad being positioned against said adhesive side of said sheet to present said hydrophilic side and said adhesive for use in contact with a wound; and

a non-sticking removable cover placed over said adhesive side of said sheet, said cover being removable to expose said pad and said adhesive.

2. A wound management device as claimed in claim 1, wherein said pad thickness ranges from 0.50 to 1.50 mm.

3. A wound management device as claimed in claim 1, wherein said fibrous sheet has a permeability of at least 173 cc/hr.

4. A wound management device as claimed in claim 1, wherein said fibrous sheet is formed from a non-woven polyester fiber.

5. A wound management device as claimed in claim 1, wherein said pad is sterlized.

6. A wound management device as claimed in claim 5, wherein said sterilization is caused by irradiation.

7. A wound management device as claimed in claim 6, wherein said irradiation is caused by the use of cobalt 60 irradiation techniques.

8. A wound management device as claimed in claim 1, wherein said cover is configured in a plow design.

9. A method of treating wounds such as burns, abrasions, lacerations and surgical incisions, comprising the steps of:

cleaning said wound;

applying a wound management dressing including a polyurethane foam pad sized to cover said wound and extending at least 2 cm beyond the wound edge, said pad having a hydrophilic side in contact with said wound and a hydrophobic side facing away from the wound, said pad being positioned on a porous, non-woven fiber sheet larger than said pad size and having an adhesive covered side in contact with the hydrophobic side, whereby said sheet adheres said pad to the wound; and

maintaining said pad in contact with said wound for up to five to seven days.

10. The method of claim 9, wherein said pad thickness ranges from 0.50 to 1.50 mm.

11. The method of claim 9, wherein said fiber sheet has a permeability of at least 175 cc/hr.

12. The method of claim 9, wherein said fiber sheet is formed from a non-woven polyester fiber.

13. The method of claim 9, wherein said pad is sterilized.

14. The method of claim 13, wherein said sterilization is accomplished by irradiation.

15. The method of claim 14, wherein said irradiation is accomplished using cobalt 60.

16. A wound management device, comprising:

a polyurethane foamed pad of a selected size and having a hydrophilic side for contact with a patient;

a porous, non-woven fibrous sheet of a larger selected size and having an adhesive on one side, said pad being positioned against said adhesive side of said sheet to prevent said hydrophilic side and said adhesive for use in contact with a wound; and

a non-sticking removable cover placed over said adhesive side of said sheet, said cover being removable to expose said pad and said adhesive.

17. A wound management device as claimed in claim 16, wherein said pad thickness ranges from 0.50 to 1.50 mm.

18. The device of claim 17, wherein said fibrous sheet is formed from a non-woven polyester fiber having a permeability of at least 173 cc/hour.

19. A method of treating wounds such as burns, abrasions, lacerations and surgical incisions, comprising the steps of:

cleaning said wound;

applying a wound management dressing including a polyurethane foam sized to cover said wound and extending at least 2 cm beyond the wound edge, said pad having a hydrophilic side in contact with said wound, said pad positioned on a porous, non-woven fibrous sheet larger than said pad size and having an adhesive side in contact with the pad, whereby said sheet adheres said pad to the wound; and

maintaining said pad in contact with said wound for up to five to seven days.

20. The method of claim 19, wherein said pad thickness ranges from 0.50 to 1.50 mm.

21. The method of claim 19, wherein said fibrous sheet is formed from a non-woven polyester fiber having a permeability of at least 175 cc/hr.
