Description

  The present invention relates to a nail deformation prevention device that can be attached to a substantially flat nail to suppress external pressure applied in a direction in which the nail is deformed and prevent nail deformation in advance.

  To keep your toes clean, wear your formal shoes (for example, pointed toe or semi-round toe) or socks with tight toes to keep your toes clean. The part may be bent by the external pressure of the footwear, and the claw edge part may be deformed into a strong curved shape so as to bite into the claw groove part. Further, if the footwear continues to move while wearing the footwear, the nail edge portion may be repeatedly pressed and released, and the nail edge portion may be fatigued and split.

  Moreover, in exercise, there are many scenes in which the weight is put on and stretched from the first and second baseballs to the nail cage during body weight movement (including kicking feet), such as shown in FIGS. 9 (1) to (2). When the nailfold is compressed, the nail edge deforms and bites into the nail groove, and this operation is repeated to cause the nailfold to swell or the soft tissue of the nail groove to lacerate. Even walking is difficult. In addition, since the appearance is essential for athletes, the swelling of the nailfolds is difficult to cure during the exercise, and if the laceration is left untreated, bacterial infection may cause suppuration. It needs to be prevented before it occurs.

A number of nail deformation correction tools for treating wound nails and ingrown nails using an elastic action have been invented. For example, the nail deformation correction tools (Patent Document 1), (Patent Document 2), (Patent Document 3). All of the nail deformation correction tools such as) are for the purpose of treating nail deformation, so even when temporarily treated, the correction tool is bent and attached to the curved shape of the deformed nail. Also, it provides flexibility along the curved shape of the nail. The elastic performance used for the treatment of the nail deformation correction tool is adjusted to an elastic force that can be gradually corrected to a flat shape after being mounted along the already deformed nail. Also from this fact, the pressure resistance and the bending resistance of the nail deformation correction tool allow at least the curved shape of the wound nail. Therefore, when the nail deformation correction tool is mounted on a flat nail, the elastic performance adjusted for the correction treatment has pressure resistance and bending resistance that can be suppressed against external pressure that bends the nail. Is not recognized, and no description of suppression of external pressure is found in each document.
