Abstract

A therapeutic device for skin lesions is provided in which adhesively coated flexible strips are stuck to skin on opposed sides of the lesion, aligned to prevent lateral displacement of the skin and drawn together by flaps to close the skin over the lesion. This device allows the lesion to heal without the formation of keloids. The flaps may be pulled around the side bars of a buckle member to draw the flexible strips to close skin over the lesion, and then the flaps stuck to the flexible strips to hold the skin closing the lesion. For surgical incisions a transparent, removable cover may be on the folded back flaps, and the surgical incision made through the transparent, removable cover, markings on the strips may be used to align them, and the lesion may be closed by sticking the flaps together in face-to-face relation.

Claims

1. A therapeutic device for skin lesions, comprising:

(a) at least two flexible strip members with an adhesive coating on one side for securing the flexible strips to skin on opposing sides of a lesion,

(b) at least one flap member for each flexible strip and secured to a portion of that flexible strip which is intended to lie alongside the lesion,

(c) means for aligning the flaps to avoid lateral displacement of the skin on the opposing sides of a lesion to which the flexible strips are to be secured by the adhesive coatings,

(d) means for drawing and holding the flexible strips closer to one another, in a direction extending across the lesion, after the strips have been secured to the skin on opposing sides of the lesion, to substantially close the skin over the lesion, and wherein the improvement comprises;

(e) a rectangular shaped buckle member having two opposite side bars around which the flaps are looped and corner portions, and

(f) means for securing the looped ends of the flaps to their respective flexible members whereby,

(g) the corner portions form said means for aligning the flaps, and the side bars together with the means for securing the looped ends of the flaps to their respective flexible members form said means for drawing and holding the flexible strips closer to one another.

2. A device according to claim 1, wherein the buckle member is in two halves, each half containing one of the side bars around which some of the flaps are looped, and further comprising wave, strip tension springs joining the ends of the two buckle halves together.

3. A therapeutic device for skin lesions, comprising:

(a) at least two flexible strip members with an adhesive coating on one side for securing the flexible strips to skin on opposing sides of a lesion,

(b) at least one flap member for each flexible strip and secured to a portion of that flexible strip which is intended to lie alongside the lesion,

(c) means for aligning the flaps to avoid lateral displacement of the skin on the opposing sides of a lesion to which the flexible strips are to be secured by the adhesive coatings, and

(d) means for drawing and holding the flexible strips closer to one another, in a direction extending across the lesion, after the strips have been secured to the skin on opposing sides of the lesion, to substantially close the skin over the lesion,

(e) a buckle member having at least two side bars around which the flaps are looped and corner portions, and,

(f) means for securing the looped ends of the flaps to their respective flexible members, whereby

(g) the corner portions form said means for aligning the flaps, and the side bars together with the means for securing the looped ends of the flaps to their respective flexible members form said means for drawing and holding the flexible strips closer to one another, and wherein the improvement comprises;

(h) a resilient, buckle cover member having a plurality of buckle engaging pins, and corresponding holes in the buckle member to the buckle engaging pins on the resilient, buckle cover member, whereby,

(i) the resilient, buckle cover member may be sprung outwardly to locate the buckle engaging pins in the holes in the buckle member.

4. A device according to claim 3, which includes a medicated, absorbent pad, and the medicated absorbent pad is secured to the flexible, buckle cover member to extend into an opening in the buckle member and into contact with a lesion, once the flexible, buckle cover member is secured to the buckle member.

5. A therapeutic device for skin lesions, comprising:

(a) at least two flexible strip members with an adhesive coating on one side for securing the flexible strips to skin on opposing sides of a lesion,

(b) at least one flap member for each flexible strip and secured to a portion of that flexible strip which is intended to lie alongside the lesion,

(c) means for aligning the flaps to avoid lateral displacement of the skin on the opposing sides of a lesion to which the flexible strips are to be secured by the adhesive coatings, and

(d) means for drawing and holding the flexible strips closer to one another, in a direction extending across the lesion, after the strips have been secured to the skin on opposing sides of the lesion, to substantially close the skin over the lesion, and wherein the improvement comprises;

(e) the flaps are paired and are folded back on the flexible strips, said means for aligning the flaps to avoid lateral displacement of the skin comprises corresponding markings on the flaps, and a transparent, removable cover on the flaps securing the strips with a gap between them.

6. A device according to claim 5, wherein said means for drawing and holding the flexible strips closer to one another comprises rods extending along the flaps and having holes at each end, and U-shaped staples which have been sprung with their sides splayed apart into the holes in the rods to clamp the flaps together.

7. A device according to claim 5, wherein said means for aligning the flaps to avoid lateral displacement of the sking further comprises adhesively coated end panels joining the ends of the flexible strip and for securement to the skin by the adhesive coatings.

8. A device according to claim 5, wherein said means for drawing and holding the flexible strips closer to one another comprises an adhesive coating on at least one of the flaps for securing the flaps together in face-to-face relation.
