Abstract

An anchor 9 for a surgical dressing includes a sheet 12 with eyelets 13 therein, said sheet attached to a layer of elastic and flexible polymeric foam 20 having an adhesive layer 30, such as a hydrocolloid or polyisobutylene adhesive. The foam is at least 10 mils thick and preferably in the range of 70 mils to 90 mils thick. The eyelets may have reinforcements 18, 24.

Claims

1. An anchor for a surgical dressing, comprising:

a sheet having a first edge and a second edge opposite to said first edge, a first portion of said sheet extending inwardly from said first edge, and a second portion of said sheet extending inwardly from said second edge to said first portion;

an eyelet, for receiving a tying device, formed in said first portion near said first edge; and

an adhesive layer substantially coextensive with said second portion;

wherein the improvement comprises;

a layer of elastic and flexible polymeric foam having one side attached between a surface of said second portion and said adhesive layer, said layer being at least 10 mils thick; and

said adhesive layer comprising a breathable, moisture-tolerant, patient-friendly adhesive disposed on a side of said foam opposite said one side.

2. An anchor according to claim 1 wherein said adhesive layer comprises a hydrocolloid or polyisobutylene adhesive.

3. An anchor according to claim 1 comprising a plurality of eyelets disposed along said first edge.

4. An anchor according to claim 1 wherein said eyelet is reinforced.

5. An anchor according to claim 4 wherein said eyelet is reinforced with a layer of sheeting adherent to said sheet.

6. An anchor according to claim 5 wherein said layer of sheeting is the same material as the material of said sheet.

7. An anchor according to claim 1 wherein said eyelet is reinforced by a flexible vinyl lamination adherent to said surface.

8. An anchor according to claim 1 wherein said sheet is a web.

9. An anchor according to claim 1 wherein said sheet is woven silk.

10. An anchor according to claim 1 including an adhesive lamina between said foam and said surface.

11. An anchor according to claim 1 wherein said layer of flexible polymeric foam is attached to said surface by an elastic polymeric film adherent to said foam and an adhesive lamina between said film and said surface.

12. An anchor according to claim 1 wherein said foam is selected from polyester or polyether polyurethane foams, and styrene-butadiene foams.

13. An anchor according to claim 12 wherein said foam is semi-open cell polyurethane foam.

14. An anchor according to claim 1 wherein said layer is between 40 mils and 120 mils thick.

15. An anchor according to claim 1 wherein said layer is between 70 mils and 90 mils thick.

16. An anchor for a surgical dressing, comprising:

a sheet having a first edge and a second edge opposite to said first edge, a first portion of said sheet extending inwardly from said first edge, and a second portion of said sheet extending inwardly from said second edge to said first portion;

an eyelet, for receiving a tying device, formed in said first portion near said first edge; and

an adhesive layer substantially coextensive with said second portion;

wherein the improvement comprises;

a layer of elastic and flexible polymeric foam having one side attached between a surface of said second portion and said adhesive layer, said layer being at least 10 mils thick; and

said adhesive layer comprising a hydrocolloid or polyisobutylene adhesive disposed on a side of said foam opposite said one side.

17. An anchor for a surgical dressing, comprising:

a sheet having a first edge and a second edge opposite to said first edge, a first portion of said sheet extending inwardly from said first edge, and a second portion of said sheet extending inwardly from said second edge to said first portion;

an eyelet, for receiving a tying device, formed in said first portion near said first edge; and

an adhesive layer substantially coextensive with said second portion;

wherein the improvement comprises;

a layer of elastic and flexible polymeric foam having one side attached between a surface of said second portion and said adhesive layer, said layer being at least 10 mils thick; and

said adhesive layer comprising a hydrocolloid adhesive disposed on a side of said foam opposite said one side.
