Abstract

A film dressing for catheter sites and a method for applying and making such a dressing are provided. Preferably, the film dressing has a foam layer. A moisture vapor semi-permeable film may be secured to the foam layer. A window in the foam layer allows for viewing of the catheter site. The moisture vapor semi-permeable film may be coated with an adhesive for application to a catheter site. The adhesive may vary in strength and pattern. The dressing may further have a liner coated with silicone for use in protection of the semi-permeable film. A label may be removable attached to the silicone coated liner. The dressing may further have additional foam pieces for use in the application of the dressing to a patient. The dressing may have different colors indicating, for example, the strength of the adhesive used with the dressing.

Claims

1. A dressing comprising:

a semi-permeable film having a top side and a bottom side;

a layer secured to the top side of the semi-permeable film;

a first adhesive on the bottom side of the semi-permeable film; and

a second adhesive on the bottom side of the layer wherein the second adhesive has an adhesive strength greater than an adhesive strength of the first adhesive.

2. The dressing of claim 1 further comprising:

a top and a bottom of the layer wherein the semi-permeable film is secured to the layer from the top of the layer to the bottom of the layer.

3. The dressing of claim 1 further comprising:

a pattern associated with the first adhesive wherein the pattern allows vapor transmission.

4. The dressing of claim 1 wherein the layer is foam.

5. The dressing of claim 1 further comprising:

a liner attached to the first adhesive and the second adhesive.

6. The dressing of claim 1 further comprising:

a piece of foam having a bottom side wherein the bottom side of the piece of foam is coated with the second adhesive.

7. The dressing of claim 1 further comprising:

a color associated with the layer wherein the color is indicative of the adhesive strength of the second adhesive.

8. The dressing of claim 1 further comprising:

a window in the layer wherein the window forms an opening in the layer.

9. A dressing comprising:

a semi-permeable film having an adhesive;

a layer having an adhesive wherein the layer is secured to the semi-permeable film; and

a liner having a top side and a bottom side wherein the top side and the bottom side are coated with silicone and further wherein the liner is secured to the layer.

10. The dressing of claim 9 further comprising:

a label removably attached to the liner.

11. The dressing of claim 9 wherein the liner is secured to the semi-permeable film.

12. The dressing of claim 9 further comprising:

a piece of foam having an adhesive wherein the piece of foam is removably attached to the liner.

13. A method for applying one of a plurality of dressings to a patient, each one of the plurality of dressings having a layer, a color associated with the layer, a semi-permeable film, an adhesive and a liner, the method comprising the steps of:

choosing a dressing based on the color associated with the layer wherein the color indicates an adhesive strength of the adhesive;

providing a piece of foam removably attached to the liner;

exposing the dressing by removing the liner;

placing the exposed portion of the dressing on the patient such that the adhesive adheres to the patient; and

securing the dressing on the patient with the piece of foam.

14. The method of claim 13 further comprising the steps of:

removing the liner; and

placing the exposed portion of the dressing on the patient.

15. The method of claim 13 further comprising the steps of:

providing a label on the dressing; and

writing information on the label.

16. The method of claim 15 further comprising the step of:

removing the label from the dressing.

17. A method for making a dressing, the method comprising the steps of:

providing foam coated on one side with a first adhesive;

securing the foam to a semi-permeable film coated with a second adhesive; and

forming a liner on the foam wherein the liner has a top side and a back side wherein the top side and the back side are coated with silicone.

18. The method of claim 17 wherein the first adhesive has an adhesive strength stronger than an adhesive strength of the second adhesive.

19. The method of claim 17 wherein the foam has a color indicative of an adhesive strength of the first adhesive.

20. The method of claim 17 further comprising the step of:

forming the liner on the semi-permeable film.

21. The method of claim 17 further comprising the steps of:

cutting pieces of foam from the foam; and

applying the foam pieces to the liner.

22. The method of claim 17 further comprising the step of:

cutting a window through the foam.

23. A dressing comprising:

a semi-permeable film having a top side and a bottom side;

a first adhesive on the bottom side of the semi-permeable film wherein the first adhesive allows vapor transmission;

a foam layer having a bottom side;

a second adhesive on the bottom side of the foam layer wherein the foam layer is secured to the top side of the semi-permeable film; and

a color associated with the foam layer wherein the color is indicative of the adhesive strength of the second adhesive.

24. The dressing of claim 23 further comprising:

a pattern associated with the first adhesive wherein variation in the pattern is indicative of a rate of the vapor transmission of the first adhesive through the semi-permeable film.
