Abstract

Claims (27)

1 . A bandage, comprising:

a flexible and wrappable bandage strip comprising a first side with a first surface coated with pressure sensitive adhesive, and on the same side as the bandage strip pressure sensitive adhesive a compressible and expandable composition retaining well is affixed at a composition retaining well base about midway along a length of the bandage strip, the composition retaining well having an aperture at a distal end forming an opening of a composition retaining well cavity defined by a vertical cavity wall, the cavity configured to receive a medicated gel composition,

wherein the composition retaining well base is made from an inert material and made of any suitable moisture-blocking material,

the composition retaining well base being shaped as one of a rectangle or oblong shape;

the composition retaining well base having an exterior wall tapering towards the aperture of the distal end at a taper angle of about 30 degrees to about 80 degrees from a composition retaining well base pyramid or cone shape;

wherein the exterior wall has a first taper along a first axis of the bandage and a second taper along a second axis,

wherein the first axis extends in the longitudinal direction of the bandage and the second axis extends perpendicular to the longitudinal direction and parallel to the first surface of the bandage;

wherein the first taper has a first taper angle and the second taper has a second taper angle, the first and second taper angles defined by the intersection of a first axis and a third axis perpendicular to the first axis and the second axis, wherein the first and second taper angles are about 30 degrees to 80 degrees from the third axis;

wherein the first taper angle and the second taper angle are different from each other within the 30 degrees to 80 degrees;

wherein the composition retaining well base at rest is about 3 millimeters to 10 millimeters in height from the base to the distal end;

wherein the composition retaining well base is compressible from about 20 to 80 percent of its height at rest when subjected to a compressive force;

wherein the composition retaining well base expands laterally in proportion to a proportionally increasing force to the composition retaining well base material as it compresses from 20 to 80 percent of its height, which expansion results in a proportional increasing reduction in the volume of the cavity from the proportionally increasing lateral contraction of the cavity wall;

wherein in use, the composition retaining well aperture is configured to first seal a periphery of a user's affected ingrown toenail area as pressure towards the user is first applied and as ever-increasing pressure is applied, the composition retaining well base proportionally expands laterally within the cavity to apply proportionally ever-increasing pressure within the cavity to drive the medicated gel composition ever deeper into the user's affected area.

2 . The bandage of claim 1 , wherein the strip and the composition retaining well base are integral.

3 . The bandage of claim 1 , wherein a cavity depth is between 100 percent to 50 percent of the height of composition retaining well base.

4 . The bandage of claim 1 , wherein the composition retaining well base is selected from a group consisting of polyethylene foam, closed foam, vinyl film, low density polyethylene foam, and combinations thereof.

5 . The bandage of claim 1 , wherein the strip is selected from a group consisting of rubber, a breathable polymeric material, a woven tricot cloth, vinyl film, cellulose and plastic web.

6 . A method of relieving pain associated with ingrown toenails, the method comprising:

providing the bandage of claim 1 ;

providing a tube of a medicated gel having 1 percent sodium sulfide;

squeezing gel into the well until it is about 50 to 100 percent filled;

aligning the aperture over an affected area of the toenail;

compressing the composition retaining well base adjacent to the affected area to laterally expand; and

wrapping the strip around the toe and releasably affixing the strip to the toe by the pressure sensitive adhesive.

7 . An ingrown toenail relief kit comprising: the bandage of claim 1 ; and a tube of a medicated gel having 1 percent sodium sulfide.

8 . The bandage of claim 1 , wherein the medicated gel composition has 1 percent sodium sulfide, is disposed within the composition retaining well and is configured to provide relief to the user's ingrown toenail.

9 . The bandage of claim 1 , wherein the first axis is parallel to a longitudinal axis of the bandage, and wherein the degree of taper angle of the first axis is greater than the second axis.
