9 Claims, 5 Drawing Figures '1 A DEVICE AND METHOD FOR CORRECTING INGROWN TOENAILS BACKGROUND 1. Field of the Invention The present invention generally relates to improved devices and methods for treating toenails and more particularly for correcting ingrown toenails.

2. Description of the Prior Art Various devices have been provided for correcting ingrown toenails. However, most such devices either are complicated and expensive to buy and use or are of little practical value. Ingrown toenails usually develop when the free portion of the toenail is cut off 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. Many of conventional corrective devices and methods apply a positive bending force on the toenail at the corner rear terminus of its free portion in an effort to force it up and out of an underlying position with the adjacent toe flesh, but such devices are difficult to place in position and may be extremely painful, particularly where the affected area is already inflamed and swollen. Moreover, in view of the initial expense of many of such devices, they must be reused to make them practical. This may necessitate cleaning and/or resterilization. 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 disposable, so that there would be no need or desire to clean and/or resterilize the same. The device should also have positive means for enabling the user to accurately and painlessly position the same for maximum effect, and should minimize trauma to the affected area.

SUMMARY OF THE INVENTION The improved device and method of the present invention satisfy the foregoing needs and are substantially as set forth in the Abstract above. In this regard, the present device employs readily available components which are easily a'ssembleable into an inexpensive but effective means of correcting ingrown toenails. The device can easily and instantaneously be removed from a protective package or the like and made ready for application to the affected area. The color of the components of the device enables them to be accurately positioned for maximum effectiveness. The device can be easily applied to the toe each night and removed in the morning for replacement or reuse each succeeding night until the ingrown toenail condition has disappeared. The nail support portion of the device acts as a guide for the growing toenail and adjacent cuticle and flesh attachment to resume their proper anatomical relationship. The nail support prevents the cuticle and flesh at the rear corner of the free portion of the toenail from continuing to overlap and encroach upon the growing toenail. All this is accomplished without the appreciable pain and discomfort associated with the use of hook and lever types of ingrown toenail correction devices.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment An improved device for correcting ingrown toenails is provided in accordance with the present invention. As shown in FIGS. 1 and 2, a device 10 is depicted which comprises a flexible self-supporting nail support 12 in the form of a thin flat plate, preferably formed of non-allergenic material such as plastic, heavily calendered paperboard, thin wood, rubber or the like. Most preferably, support 12 is fabricated of polyethylene sheet or similar thermoplastic sheet material, which is very inexpensive, but is attractive and has the described requisite properties. At least a portion of nail support 12 is releasably secured to a protective strip 14 by an adhesive layer 16 preferably carried on strip 14, as shown in FIG. 1.

Strip 14 can be fabricated of any suitable flexible material, such as cellulosie or plastic web material or the like to which layer 16 is applied. Preferably, layer 16 comprises a permanently tacky material such as a rubber base adhesive or the like. Layer 16 on strip 14 functions as attaching means for releasably holding device 10 in place around a toe.

When device 10 is to be used, an end portion or corner of nail support 12 is separated from protective strip 14 and adhesive layer 16 and the detached portion is then fitted between the free portion of a toenail and the adjacent underlying cuticle and/or toe flesh to abut a rear corner terminus of said free toenail portion. The remainder of nail support 12 is reflected (bent) around the front of the toe and device 10 is then releas-ably held in place on the toe by adhesive layer 16 on protective strip 14. Strip l4 acts to protect the toe and nail support 12 from relative movement and from ingress of dirt, etc. Usually, device 10 is applied each night before 'going to bed and is removed upon arising in the morning. Device 10, due to adhesive layer 16, can be reused or can be replaced each night with an identical unit utilized in the described manner in accordance with the present method. Placement of nail support 12 in the described manner exerts a guiding effect on the growing toenail and adjacent cuticle and toe flesh at the point (corner) where the toenail is overlapped by the cuticle and/or flesh. Thus, it acts as a barrier against the cuticle and/or flesh continuing to grow around and over the emerging toenail, and thereby corrects the ingrown condition of the toenail. Device 10 is simple, effective, economical and easy to use and is easily replaceable. Second Embodiment FIGS. 3, 4 and 5 schematically depict a second embodiment of the device of the invention. As shown in those figures, a device 20 is provided which comprises a nail support 22 releasably connected on one side thereof to a protective strip 24 by means of an adhesive layer 26 carried on strip 24. Support 22 is releasably connected on the opposite side thereof to one or a plurality such as a pair of spaced backing strips 28 by means of adhesive layers 30 carried by strip 28 on one side thereof. The spacing of strips 28 is to facilitate peeling of one or both strips 28 partially or wholly from nail support 22. As an alternative, the strips 28 may overlap if desired and the adhesive layer 30 between the support 22 and strips 28 may be omitted to facilitate removal of the strips 28 in preparation for use. Also, although the support 22 or 12 (FIGS.-1 and 2) is shown disposed transversely of the strip 24, it may as well be mounted longitudinally thereof and extending only partially across the width of the strip 24. in either case, use of the device of the invention is essentially the same.

A preferred way of utilizing devices in accordance with the present method is schematically illustrated in FIG. 5. Thus, in FIG. 5 a toe 34 is shown, with toenail 36 ingrown in the area 38. Device 20 has had one of backing strips 28 removed so as to expose one end 40 of nail support 22. End 40 is placed between toenail 36 and the adjacent flesh and cuticle in the area 38, as shown in FIG. 5. Layer 26 on strip 24 acts to releasably hold device 20 in place around toe 34 with the remainder of nail support 22 bent around the front end of toe 34. Strip 24 acts to protect nail support 22 and toe 34, and particularly area 38, from dirt and infection while holding the portion 40 of nail support 22 in the desired therapeutic position in area 38 to obviate the ingrown toenail condition.

Accordingly, devices in accordancewith the invention provide simple, effective and inexpensive means for correcting ingrown toenails in accordance with the present method. Components of device 20 similar to those of device can be fabricated of the same or similar materials. The backing strips 28 can be fabricated of any suitable material, such as those described for strip 24 and strip 14.

It is also contemplated as part of the present invention preferable to provide nail supports 12 and 22, and most preferably also strips 14 and 24, with one or more colors contrasting with the colors'of the toenail, toe cuticle and toe flesh to facilitate proper alignment of nail supports 12 and 22 with the ingrown areas of the toe. Strips 28 can also be provided with contrasting colors. Where one's toenail is ingrown on both sides, two separate devices such as 10 or may be applied to the respective corners of the nail 36. Since

devices

10 and 20 are relatively flat and flexible, portions thereof can overlie one another very easily in a double application without discomfort and without impairing their effectiveness. Further advantages of the device of the present invention and the present method are as set forth in the foregoing.
