Patent Application
20230000691
Presented herein are devices and methods for use in relieving pain associated with ingrown toenails, and in particular devices and methods for relieving ingrown toenails using a bandage wrap having a compressible/expandable well configured to receive over-the-counter (OTC) ingrown toenail relief products.
Onychocryptosis is a nail condition where a lateral edge of a nail plate pierces tissue in or directly under a lateral nail fold. This condition is more commonly known as an ingrown toenail. Ingrown toenails can develop when the distal portion of the toenail is cut too short, thereby allowing the cuticle and toe flesh at the corner of the emerging toenail (rear corner terminus of the free portion of the toenail) to overlap the toenail, thus causing inflammation, swelling and pain.
Sulfides, such as sodium sulfide nonahydrate, (hereinafter referred to as sodium sulfide), are effective keratolytic agents for softening nails. According to the Federal Register, over-the-counter ingrown toenail relief drug products in a form suitable for topical administration can, under certain circumstances, be generally recognized as safe and effective (for example sodium sulfide 1 percent in a gel vehicle). (See generally, Federal Register Vol. 68, No. 88, May 7, 2003; pages 24347-24349)
Various medicated devices and methods using, for example, sodium sulfide or conventional antibiotics such as mercurochrome have been provided to correct or relieve pain associated with an ingrown toenail (See, generally, U.S. Pat. Nos. 5,770,583; 3,464,408 and 3,799,160). However, most such devices either are complicated to use, expensive or of little practical value. For example, the device may not be able to adequately and deliberately direct and hold the medication on the affected area and may not provide a sufficient quantity of medication.
Accordingly, it would be desirable to provide a simple, inexpensive, but highly effective device for such purposes and a simple method of use of the same. Preferably, such a device should be easily applied to an affected area and easily disposable.
It is to be understood that if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art.
Accordingly, to advance at least the aforementioned deficiencies in the art, described herein is a simple, easily used, wrapable bandage for use in relieving pain associated with ingrown toenails. The present embodiments provide a device to deliberately and effectively direct and hold a sufficient quantity of medication against an affected area, such as an ingrown toenail.
According to one approach, a bandage is provided having a flexible and wrapable bandage strip coated on one side with pressure sensitive adhesive, and on the same side as the pressure sensitive adhesive a compressible and expandable composition retaining well having an aperture configured to receive a medicated gel composition is affixed at its base about midway along a length of the strip; wherein the composition retaining well at rest is about 3 millimeters to 10 millimeters in height from its base to the aperture and having sides sloping towards the aperture of about 30 degrees to about 80 degrees. In one embodiment the strip and the composition retaining well can be integral.
In various embodiments, the composition retaining well can be compressible from about 20 to 80 percent of its height at rest. The well depth can be between 100 percent to 50 percent of the height of the composition retaining well. The composition retaining well can be made from an inert material and made of any suitable moisture-blocking material. The composition retaining well can be selected from the group consisting of polyethylene foam, closed foam, vinyl film, low density polyethylene foam, and the like, and combinations thereof. The strip can be selected from the group consisting of rubber, a breathable polymeric material, a woven tricot cloth, vinyl film, cellulose and plastic web. The composition retaining well can be configured to receive a medicated gel having 1 percent sodium sulfide.
According to one approach, a method of relieving pain associated with ingrown toenails may have the steps of providing a bandage having a flexible and wrapable bandage strip coated on one side with pressure sensitive adhesive, and on the same side as the pressure sensitive adhesive a compressible and expandable composition retaining well having an aperture configured to receive a medicated gel composition is affixed at its base about midway along a length of the strip; wherein the composition retaining well at rest is about 3 millimeters to 10 millimeters in height from its base to the aperture and having sides sloping towards the aperture of about 30 degrees to about 80 degrees; 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 adjacent to the affected area; and wrapping the strip around the toe and releasably affixing the strip to the toe by the pressure sensitive adhesive.
According to another approach, an ingrown toenail relief kit is provided having a bandage having a flexible and wrapable bandage strip coated on one side with pressure sensitive adhesive, and on the same side as the pressure sensitive adhesive a compressible and expandable composition retaining well having an aperture configured to receive a medicated gel composition is affixed at its base about midway along a length of the strip; wherein the composition retaining well at rest is about 3 millimeters to 10 millimeters in height from its base to the aperture and having sides sloping towards the aperture of about 30 degrees to about 80 degrees; and a tube of a medicated gel having 1 percent sodium sulfide.
Other aspects of the invention are also disclosed and will become more apparent to persons having ordinary skill in the art to which the devices pertain and from the following description and claims.
Notwithstanding any other forms which may fall within the scope of the present invention, preferred embodiments of the disclosure will now be described, by way of example only, with reference to the accompanying drawings in which:
While the features described herein may be susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the drawings and detailed description thereto are not intended to be limiting to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the subject matter as defined by at least the appended claims.
The present embodiments provide a flexible strip having on one side a pressure sensitive adhesive and a compressible/expandable well to receive compositions therein. In use, the pressure sensitive adhesive may be applied to a surface to hold and compress the well against the surface thereby exposing the surface adjacent the opening/aperture of the well to the composition contained therein. Although the present embodiments are demonstrated as a bandage wrap having a compressible/expandable well configured to receive over-the-counter (OTC) ingrown toenail relief products, it is understand that present embodiments may be used wherever any composition is desired to be maintained adjacent a surface.
Thus, accordingly to one exemplary approach, presented herein are simple easy to use devices configured to assist in relieving pain associated with ingrown toenails by deliberately and effectively applying medication disposed within a compressible/expandable well against an affected area.
The present figures provide an exemplary use of the device of the present embodiments. A device 20 (shown herein as a bandage wrap) is comprised of a flexible/wrapable bandage strip 22 coated on one side with pressure sensitive adhesive 21. Pressure sensitive adhesive 21, can be a permanently tacky material like an acrylic adhesive, rubber base adhesive, or the like. Pressure sensitive adhesive 21 functions as an attaching means for releasably holding device 20 in place around a toe 48 so that an aperture of a well having a medicated gel can be directly, firmly and consistently applied to an affected area.
Strip 22 can be made of rubber, a breathable polymeric material, a woven tricot cloth, vinyl film, cellulose, plastic web and the like so long as it is flexible and wrapable, and optionally stretchable. Strip 22 has on the same side as the pressure sensitive adhesive a composition retaining well 16 having a well/opening/bore 14, the underside/base of which is attached to strip 22 either by the pressure sensitive adhesive 21 or by a separate more permanent adhesive (not shown). Composition retaining well 14 should be an essentially inert material and can be made of any suitable moisture-blocking material, such as polyethylene foam, closed foam, vinyl film, low density polyethylene foam, and the like.

As shown in the figures, composition retaining well 14 may be a pyramid or a cone shape or any variation between a pyramid and cone shape. The cone base may be round or oblong and the pyramid base may be square or rectangular. The angles of slopes 28 (
Composition retaining well 14 not only protects the skin and retains the sulfide-containing gel in place on the afflicted ingrown toenail area, but also through the compression of composition retaining well 14 adds a greater, more effective seal and greater and more effective pressure of gel 34 onto the affected area of nail 38. Thus, the present embodiments provide a superior ability to seal and drive medicated gels into affected areas. The exposed portion of composition retaining well 14 may optionally also have has a pressure sensitive adhesive for attaching to the toe.
