Abstract

Improvements in skin closures that unite and hold separable closure members and skin portions attached thereto accurately together to prevent separation thereof by forces which might otherwise cause the united members to separate, the improvement including sheet members adhesively attached on opposite sides of a skin separation or incision and one or more folded back sheet portions or separate sheet elements for use in adhesively connecting the sheet members about the skin separation or incision thereby closing the skin separation or incision. In addition, the improvement includes protective coverings over the adhesive layers for use in protecting the adhesive until such time as it is necessary to utilize the skin closure. The improvement also can include elements to aid in accurately guiding a scapel as it makes an incision through the skin closure to aid in preventing damage to the skin closure that would impair its ability to function as such.

Claims

1. A device for closing a skin separation comprising first and second sheet members each having opposite surfaces and means forming a side edge therealong, the means forming a side edge along the first sheet member for extending along one side of a skin separation to be closed and the means forming a side edge along the second sheet member for extending along the other side of the skin separation to be closed, said first sheet member having an adhesive on one of the opposite surfaces for attaching it to a skin surface with the side edge thereon extending along one side of the skin separation to be closed, said second sheet member having a flap portion attached thereto along the side edge thereof to form a continuation of the second sheet member, the said means forming the side edge of the second sheet member being formed by folding the flap portion back on the second sheet member to define a folded sheet edge therealong, said flap portion being movable relative to the second sheet member between the folded back position thereof in surface to surface contact with the second sheet member and a second position bridging the skin separation and movable into surface to surface contact with the first sheet member, means on one opposite surface of the second sheet member for adhesively attaching it to the skin with the folded side edge thereof extending along the other side of the skin separation to be closed, and means for attaching the flap portion to the first sheet member in the second position thereof.

2. The device of claim 1 including means to attach the flap portion to the second sheet member in the first position thereof.

3. The device of claim 1 including a protective covering for the skin attaching adhesive on said first and second sheet members.

4. The device of claim 1 including an adhesive and a protective covering for both opposite surfaces of the first sheet member.

5. The device of claim 4 wherein the flap portion has an adhesive on the surface thereof movable into engagement with the first sheet portion in the second position thereof.

6. The device of claim 1 wherein the first and second sheet members are formed of a flexible material.

7. The device of claim 1 wherein the first and second sheet members are formed of flexible, open netting material.

8. Means to close a skin separation by bringing together skin portions along opposite sides of the separation comprising a sheet member formed by first and second sheet portions of flexible material, each of said sheet portions having opposite surfaces and each of said sheet portions having a side edge for positioning extending along respective opposite sides of a skin separation to be closed, a layer of an adhesive on corresponding surfaces of each of said sheet portions for attaching the respective sheet portions to a skin surface at locations extending along opposite sides of the skin separation to be closed, a flap portion of said first sheet portion foldable back against said first sheet portion to form a folded edge extending along and defining the aforesaid side edge thereof, means between the flap portion of said first sheet portion and the first sheet portion to hold them together in folded condition, the means holding the flap portion to the first sheet portion being separable for movement of the flap portion to an unfolded position with respect thereto and to a position extending over and across the skin separation and over a portion of said second sheet portion, and means for attaching the flap portion to the second sheet portion to hold the first and second sheet portions and the opposite side edges of the skin separation together.

9. The skin closure means of claim 8 including a layer of adhesive provided on both opposite surfaces of said second sheet portion.

10. The skin closure means of claim 8 including a removable protective cover member extending over the adhesive layers on the corresponding surfaces of each of the first and second sheet portions.

11. The skin closure means of claim 8 including an adhesive layer extending over opposite surfaces of the second sheet portion and over opposite surfaces of the first sheet portion including the flap portion, a first protective cover member extending over the adhesive layers on corresponding surfaces of the first and second portions, and a second protective cover member extending over the adhesive layer on the opposite surface of the second sheet portion and over the corresponding opposite surface of the flap portion of the first sheet portion.

12. The skin closure means of claim 8 wherein the first and second sheet portions are formed of a perforated material.

13. The skin closure means of claim 8 wherein the first and second portions are formed of an open netting material.

14. Skin closure means for closing a skin separation having adjacent side edges comprising a pair of sheet members formed of flexible material characterized by being able to intimately conform to a skin surface, each of said sheet members having opposite surfaces and a side edge, the side edges on the respective sheet members being adapted to be adjacent to one another, a corresponding one of said opposite surfaces of each member having an adhesive substance thereon to enable it to adhesively attach to a skin surface with the adjacent side edges extending along the respective side edges of the skin separation when the skin separation is closed, and means for cooperatively engaging the respective sheet members with the side edges thereof and with the side edges of the skin separation attached thereto in position closing the skin separation, the means for cooperatively engaging the respective sheet members including a flap portion forming a continuation of one of said sheet members along the side edge thereof.

15. The skin closure means of claim 14 including means for adhesively attaching the flap portion to the other sheet member.
