Abstract

Claims (29)

1. A PIV window dressing assembly for the protection of a PIV catheter insertion site that is interchangeably usable on both a right or left-hand side insertion site and that resists detachment from a patient's skin during use, the dressing assembly comprising:

a fabric layer that is bounded by an edge, said fabric layer having an adhesive side, an opposite non-adhesive side, and at least one opening therein to allow for viewing therethrough;

at least one-reinforcement member disposed between the fabric layer edge and said opening, said reinforcement member being adhered to the fabric layer adhesive side and being generally of an H-like shape, and said reinforcement member distributing pull forces exerted on said dressing assembly over a larger surface area and resisting peeling of said dressing assembly from a patient's skin;

a recess in the fabric layer edge corresponding with the location of each H-like shaped reinforcement member; and

a transparent film layer having an adhesive skin adhering side and an opposite non-adhesive side, said film layer closing each of said at least one opening in said fabric layer, said film layer non-adhesive side being adhered to the fabric layer adhesive side.

2. The PIV dressing assembly of claim 1 , wherein each of said at least one reinforcement member has an adhesive side and an opposite non-adhesive side, the reinforcement member non-adhesive side being adhered to the fabric layer adhesive side.

3. The PIV dressing assembly of claim 1 , including at least one slit in the fabric layer edge.

4. The PIV dressing assembly of claim 3 , wherein each said at least one slit is disposed along a length of the fabric layer edge generally opposite said reinforcement member.

5. The PIV dressing assembly of claim 3 , wherein each said at least one slit is one of a cut line and a perforated line.

6. The PIV dressing assembly of claim 1 , including a plurality of recesses disposed along a length of the fabric layer edge.

7. The PIV dressing assembly of claim 6 , wherein said recesses are disposed along a length of the fabric layer edge generally opposite said reinforcement member.

8. The PIV dressing assembly of claim 1 , wherein a portion of the fabric layer edge has a curved shape disposed along a length of fabric layer edge opposite said reinforcement member.

9. The PIV dressing assembly of claim 1 including at least one perforation line extending inwardly from the fabric layer edge, said at least one perforation line being disposed along a length of the fabric layer edge adjacent said reinforcement member.

10. The PIV dressing assembly of claim 9 including a landmark notch along the fabric layer edge contiguous with each of said at least one perforation line for indicating the location of said at least one perforation line.

11. The PIV dressing assembly of claim 1 , wherein said dressing assembly has a central axis that spatially divides said dressing assembly into first and second portions, said first and second portions being mirror images of each other.

12. The PIV dressing assembly of claim 1 , wherein said dressing assembly is generally one of a rectangular and square shape.

13. The PIV dressing assembly of claim 1 , including a release liner having a tackless side contacting said adhesive side of said film layer, said release liner generally extending to said edge of said fabric layer.

14. The PIV dressing assembly of claim 13 , wherein said release liner includes a first piece and a second piece, said first and second pieces being folded such that each of said first and second pieces have a tab formed by the fold; whereby one of said pieces can be released from said dressing assembly without tampering with the other of said pieces.

15. The PIV dressing assembly of claim 1 , including a wallet, wherein said dressing assembly is folded and inserted into said wallet.

16. The PIV dressing assembly of claim 15 , wherein said wallet includes a folded release liner.

17. A PIV window dressing assembly for the protection of a Ply catheter insertion site that is interchangeably usable on both a right or left-hand side insertion site and that resists detachment from a patient's skin during use, the dressing assembly comprising:

a fabric layer that is bounded by an edge, said fabric layer having an adhesive side, an opposite non-adhesive side, and at least one opening therein to allow for viewing therethrough;

at least one reinforcement member disposed between the fabric layer edge and said opening, said at least one reinforcement member being adhered to the fabric layer adhesive side, said at least one reinforcement member; and

distributing pull forces exerted on said dressing assembly over a larger surface area and resisting peeling of said dressing assembly from a patient's skin;

a recess in the fabric layer edge corresponding with the location of each said at least one reinforcement member;

a transparent film layer having an adhesive skin adhering side and an opposite non- adhesive side, said film layer closing each of said at least one opening in said fabric layer, said film layer non-adhesive side being adhered to the fabric layer adhesive side; and

at least one closure member, each said at least one closure member having an adhesive side and an opposite non-adhesive side, wherein each said at least one closure member is disposable on said fabric layer about the fabric layer edge at a location corresponding with said at least one reinforcement member.

18. The PIV dressing assembly of claim 17 , wherein one of said at least one closure member includes a recess.

19. The PIV dressing assembly of claim 17 , wherein each closure member generally has a circular shape.
