However, the inventor of the present application has found that the nail protector described above has the following problems.

Cleavage of onycholysis with bifurcated nail tip edge or bifurcated nail edge dehiscence of onycholysis, the opening and the origin of the dehiscence In order to prevent the deterioration and progress of each nail edge end opening (hereinafter referred to as an opening), the opening is fixed so as to be closed, and the bifurcated nail edge end forming the opening is formed. It is necessary to stop the development of fatigue cleavage or fatigue dehiscence due to the opening and closing movement of the dehiscence site. The nail protector described in Document 1 is provided with a nail protection portion that is attached to the nail plate and a hook-shaped locking portion that is hooked to the nail edge portion. Certainly, the effect of protecting the crack portion can be found by contacting the nail plate side so as to cover the crack. However, in the opening that develops like a dehiscence at the claw edge, only a hook-shaped locking portion is hooked, and the opening and closing movement of the opening is not fixed so as to be able to close. As a result, the opening causes an opening / closing-like movement in the hook-shaped locking portion, which not only causes fatigue dehiscence or fatigue fracture of the onset opening site, but also causes contact with the nail plate side. There is a problem of inducing the attachment / detachment of the nail protection portion.

For example, it is a case where the nail protective device described in Document 1 is attached to a nail in which nail rim fissure has developed on the side edge of the first toenail and the person walks. When observing the movement of the nail edge of the opening in the locking portion provided on the nail protector, since the opening is not closed and fixed, the time between the time of landing on the sole of the foot during walking, the time of standing, and the time of taking off the toe. In this series of movements, the first toenail claw is pressed from the ground, a ridge is generated, and the opening is widened. Next, when the leg is released from the ground, the claw cage released from the pressure on the ground returns to normal, and the opening is closed. In this way, each time one step is taken, the opening continuously opens and closes in the locking portion, so that the opening may cause fatigue dehiscence and a linear crack may extend to the nail plate side. be. If it gets worse, there is a risk of fatigue fracture from the linear crack portion and development of a nail plate defect. From this, it was clarified that the nail protector described in Document 1 is not suitable for protecting the nail margin dehiscence. Further, even in the case of cleavage that develops at the tip edge of the nail, it seems difficult to prevent fatigue peeling because the cleavage portion cannot be closed and fixed only by hooking at the locking portion.

As described above, the nail protector described in Document 1 protects the shape of the nail plate and the crack of the nail plate. There is no description or suggestion of the effect of closing the opening.

An object of the present invention is to protect the opening of the nail tip edge opening or nail edge dehiscence that has developed on the nail tip edge, and also to remove the nail tip edge fatigue or fatigue dehiscence of the nail edge fissure opening or the dehiscence portion. It is an object of the present invention to prevent the risk of nail plate defect due to fatigue fracture, and to provide a nail protector capable of protecting the opening and preventing nail plate defect due to fatigue peeling or fatigue fracture.

The nail protector of the present invention for solving the above problems is composed of the following technical means.

That is, according to the first aspect of the present invention, the opening which is the starting point of the onset of the tip edge of the nail and the tear of the edge of the nail and the edge of the vicinity of the periphery of each of the above-mentioned openings are inserted into the accommodating gap, and then the metal protector is used. By pressurizing and plastically deforming the plastically deformed portion so that at least one of the first leg and the second leg provided is in close contact with the opening, the opening is clamped and fixed in a closed state. The opening and closing movement of the opening can be stopped, fatigue dehiscence or fatigue peeling can be prevented, and the nail plate defect due to fatigue fracture of the linear crack portion developed on the nail plate can also be prevented. In the claw protector, a rectangular flat plate made of at least one selected appropriately plastically deformable material from a metal or a polymer compound is used and bent from a joint so as to face each other to form a substantially U-shaped cross section. The mimicking first and second legs form a containment gap into which the claw edge can be inserted in an inset, and at least one of the first leg and the joint is made of metal. From the material, use a shape that allows plastic deformation by controlling the yield point of the plastic or elastic material, or from the resin material, volatile curable resin, thermosetting resin, energy ray curable resin, polyfunctional acrylate. Using a single material or composite material appropriately selected from each material such as a monomer, the opening is closed with a plastically deformable portion formed to be plastically deformable by pressurization of either pressing or pinching. It is a claw protector that can be pinched and fixed in the state.

The invention according to claim 2 has elasticity capable of holding and fixing the opening developed in the claw edge to at least one of the first leg portion and the joint portion provided in the claw protector according to claim 1 in a closed state. It has an elastic acting part selected from a metal, resin, rubber, elastomer or composite material having elastic stress to generate pinching pressure, and is configured to be able to pinch and fix the opening in a closed state. Is.

As described above, according to the above configuration of the present invention, the opening / closing movement of the opening can be closed by the configuration of the nail protector capable of fixing the opening of the nail tip cleavage or the nail edge cleavage in the closed state. Fatigue cleavage or fatigue peeling can be prevented, and the nail plate defect due to fatigue fracture of the linear crack portion developed on the nail plate can also be prevented.
