Abstract

Devices, kits and methods described herein include skin treatments with a book-like packaging, applicator and/or tensioning device used to apply a dressing to a subject. The packaging, applicator and/or tensioning device is used to apply and/or maintain a strain in an elastic dressing, and has a first support, a second support, and a primary bending region therebetween, the primary bending region comprising a primary bending axis, with the dressing attached to the first and second supports of the device.

Claims

1. A dressing system, comprising:

a first support, a second support, and a primary bending region therebetween, the primary bending region comprising a primary bending axis; and

a treatment device comprising a first attachment region attached to the first support and a second attachment region attached to the second support, a first separation region configured to separate from the first attachment region, a second separation region configured to separate from the second attachment region, wherein the first and second separation regions comprise perforations, and a pull element located along the perforations;

wherein the treatment device further comprises a release liner coupled to an adhesive surface of the treatment device.

2. The dressing system of claim 1, wherein the treatment device is asymmetrically attached to the first and second supports, relative to the primary bending region.

3. The dressing system of claim 1, wherein a first distance between the first support and the primary bending axis is different from a second distance between the second support and the primary bending axis.

4. The dressing system of claim 1, wherein the second support comprises at least one secondary bend region comprising a secondary bending axis that is not parallel to the primary bending axis.

5. The dressing system of claim 4, wherein the secondary bending axis is orthogonal to the primary bending axis.

6. The dressing system of claim 4, wherein the first support comprises at least one secondary bend region comprising a secondary bending axis that is not parallel to the primary bending axis.

7. The dressing system of claim 6, wherein the at least one secondary bend region of the first support is aligned with the at least one secondary bend region of the second support.

8. The dressing system of claim 1, further comprising an elongate element attached adjacent to at least one of the perforations of the first or second separation regions.

9. The dressing system of claim 8, wherein the elongate element protrudes beyond at least one of the perforations of the first or second separation regions.

10. The dressing system of claim 8, wherein at least a portion of the elongate element is folded.

11. The dressing system of claim 1, wherein at least one of the first and second supports comprises indicia identifying a center region of the treatment device.

12. The dressing system of claim 11, wherein the indicia comprises a recessed edge, ink mark, embossing, or window.

13. The dressing system of claim 1, wherein the primary bending region is perforated.

14. The dressing system of claim 13, wherein the first support is configured to detach from the second support and the treatment device.

15. The dressing system of claim 14, wherein the first support is configured to detach from the second support and the treatment device while maintaining the treatment device in a strained configuration.

16. The dressing system of claim 1, wherein the second support comprises an adhesive element configured to adhere to the treatment device when the dressing system is in the open configuration but not in the closed configuration.

17. The dressing system of claim 1, wherein the release liner is attached to the first support.

18. The dressing system of claim 17, wherein the release liner is attached to the first support between an outer edge of the first support and the attached treatment device.

19. A dressing system, comprising:

a first support, a second support, and a primary bending region therebetween, the primary bending region comprising a primary bending axis;

a treatment device comprising a first attachment region attached to the first support and a second attachment region attached to the second support, a first separation region configured to separate from the first attachment region and a second separation region configured to separate from the second attachment region, wherein the first and second separation regions comprise perforations, and a pull element located along the perforations; and

wherein the dressing system further comprises a closed configuration wherein the treatment device is located between the first support and the second support, and an open configuration wherein the second support is located between the first support and the treatment device.

20. A dressing system, comprising:

a first support, a second support, and a primary bending region therebetween, the primary bending region comprising a primary bending axis; and

a treatment device comprising a first attachment region attached to the first support and a second attachment region attached to the second support, a first separation region configured to separate from the first attachment region and a second separation region configured to separate from the second attachment region;

wherein the second support comprises an adhesive element configured to adhere to the treatment device when the dressing system is in an open configuration but not in a closed configuration.

21. The dressing system of claim 20, wherein the first support and second support are configured to be separated.

22. The dressing system of claim 20, wherein the treatment device is in a strained configuration when the dressing system is in the open configuration, and the adhesive element is configured to maintain the treatment device in the strained configuration.

23. The dressing system of claim 20, wherein the adhesive element is located adjacent the second attachment region.

24. The dressing system of claim 20, wherein the second support comprises an edge adjacent the primary bending region and wherein the adhesive element is located between the edge and the second attachment region when the dressing system is in an open configuration.

25. The dressing system of claim 20, further comprising a removable release liner positioned over the adhesive element.
