Abstract

A process for the reduction of pain in the removal of adhesive tapes and bandages which comprises applying to a region of receptor cells, such as in human skin, adhesive tapes and bandages comprising a flexible backing with an adhesive portion distributed and adhered thereon in the form of adhesive layers alternately spaced with regions of lesser adhesiveness, such as no adhesiveness or lesser adhesive or no adhesive, therebetween, each region of lesser adhesiveness generally of a width less than each adjacent successive layer of adhesive, with each region having a minimum width of about 0.02 inches, and removing such tapes and bandages to provide successive stimuli to cells in the receptor region so as to reduce the frequency-dependent responsiveness of the cells, thereby reducing the pain in removal.

Claims

1. A process for the reduction of pain or discomfort in the removal of a tape from a receptor region comprising receptor cells, which process comprises removing an adhesive tape from a receptor region of receptor cells subject to excitation by stimuli, which tape comprises a backing and an adhesive portion comprising a plurality of adhesive layers and a plurality of regions of lesser adhesiveness, the layers adhered with the regions of lesser adhesiveness between such layers, the regions and layers being straight and successively alternating along the longitudinal length of said backing, each layer and each region characterized generally by a uniform width and having a minimum width of about 0.02 inches, the number of said layers or regions per linear inch of tape being from 4 to about 25, the removal being generally perpendicular to the longitudinal edges of the tape, thereby reducing frequency-dependent responsiveness of the receptor cells upon removal of the contacted tape.

2. The process of claim 1 wherein each said region is characterized by a width less than the width of said successive adjacent layer.

3. The process of claim 1 wherein said tape comprises said layers and regions which are angled.

4. The process of claim 1 wherein said tape comprises said layers and regions which are curved.

5. The process of claim 1 wherein said regions extend across the entire width of said backing.

6. The process of claim 1 wherein said regions extend less than across the entire width of said backing.

7. The process of claim 1 wherein said regions of lesser adhesiveness comprise permanent facings adhering to adhesive on said backing.

8. The process of claim 1 wherein said regions of lesser adhesiveness comprise an adhesive of lesser adhesiveness than the adhesive of said layers.

9. The process of claim 1 wherein said regions of lesser adhesiveness comprise regions of no adhesiveness.

10. The process of claim 1 which comprises an absorbent body portion secured thereon.

11. The process of claim 1 wherein the said regions comprise regions of lesser adhesive.

12. The process of claim 1 wherein the said regions comprise regions of no adhesive.

13. The process of claim 1 wherein the said regions include a flexible facing adhered to an underyling continuous somewhat Smooth adhesive coating.

14. The process of claim 1 wherein said regions include a flexible facing composed of the backing material adhered by adhesive-to-adhesive contact with an underlying somewhat smooth adhesive coating.

15. The process of claim 1 wherein the width of each of said layers of adhesive does not exceed 0.25 inches.

16. The process of claim 1 wherein the width of each of said regions is about 0.03 inches.

17. The process of claim 1 wherein the said regions vary in adhesiveness within each of the regions.

18. The process of claim 1 wherein the regions and layers extend across the entire width of the tape, and the regions and layers being straight and alternating along the longitudinal length of the backing, all regions and layers being of the same width.

19. The process of claim 1 wherein said tape comprises a backing and an adhesive portion having a plurality of said layers and regions on both sides of said backing.

20. The process of claim 1 wherein said layers vary in adhesive.

21. The process of claim 1 wherein said layers vary in adhesiveness.

22. The process of claim 1 wherein each of said layers varies in adhesive.

23. The process of claim 1 wherein each of said layers varies in adhesiveness.

24. A process for the reduction of pain or discomfort in the removal of a tape from a receptor region comprising receptor cells, which process comprises removing an adhesive tape from a receptor region of receptor cells subject to excitation by stimuli, which tape comprises a backing and an adhesive portion comprising a plurality of adhesive layers and a plurality of regions of no adhesive, the layers adhered with the regions of no adhesive between such layers, the regions and layers being straight and successively alternating along the longitudinal length of said backing, each layer and each region characterized generally by a uniform width and having a minimum width of about 0.02 inches, the width of each layer being less than 0.25 inches, the number of said layers or regions per linear inch of tape being from 4 to about 25, each region extending across the entire width of said backing, and the tape including an absorbent body portion secured thereon, thereby reducing frequency-dependent responsiveness of the receptor cells upon removal of the contacted tape from the receptor region.
