Abstract

<P>PROBLEM TO BE SOLVED: To prevent an ingrown nail by reducing the degree of a curve in a curved nail tended to be the ingrown nail. <P>SOLUTION: An ingrown nail preventing implement comprises: an upper surface fixing part (1); a lower surface fixing part (2); and a pressure belt (3) arranged at the center of the upper surface fixing part (1). The pressure belt (3) causes a center at the distal end of the nail (4) to be deformed downward. Thus, both side ends of the distal end of the nail (4) are deformed upward and outward to thereby reduce the degree of the curve in the nail (4). <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention corrects the shape of a nail that tends to become a wound nail and prevents it from becoming a wound nail.

A wound nail is a state in which a normal nail having a shape as shown in FIG. 6 gradually incurs curvature over a period of days and bites into a finger as shown in FIG. In order to treat or prevent this, conventionally, as shown in FIGS. 9 and 10, the elastic plate (13) is attached in the lateral direction of the nail along the curvature of the nail, or as shown in FIGS. Some have tried to return the curvature of the nail to flat using the repulsive force of the elastic plate (13) by hooking the elastic plate (13) to both ends of the nail.
In addition, as shown in FIG. 13 and FIG. 14, there are some that use a wire (15) or the like, but they all tried to lift both side ends of the claw (4) directly outward and upward.

These have the following drawbacks.
(A) In order to prevent the elastic plate (13) from peeling off from the nail (4), a strong adhesive had to be used.
(B) The nail (4) has a layered structure in which many layers are overlapped, and when the elastic plate (13) applies a pulling force to the surface of the nail (4), the nail (4) is peeled off in layers. .
(C) As shown in FIGS. 11 and 12, when the elastic plate (13) is hooked on both ends of the nail (4), the elastic plate is not extended to some extent from the tip of the finger (5). (13) does not enter the lower side of both ends of the nail (4) and cannot be used.
(D) In the case of using a wire as shown in FIGS. 13 and 14, a hole (16) must be made in the nail (4), so that the nail (4) extends to some extent from the tip of the finger (5). It cannot be used without it.

The upper surface fixing portion (1) and the lower surface fixing portion (2) are connected, and the pressure band (3) is installed at the center of the upper surface fixing portion (1).
The present invention is a curly nail preventer having the above-described configuration.

The present invention applies a downward force to the center of the tip of the curved nail (4) and deforms the center of the tip of the nail (4) downward as shown in FIG. Both side ends of the are deformed outward and upward as shown in FIG.
As shown in FIG. 8, if a downward force is applied to the center of the tip of the semi-cylinder (8) whose rear end is fixed, both side ends of the tip are deformed outward and upward. It is to be done.
As a result, the nail (4) is less bent and the claw is prevented.
Unlike the prior art, the present invention is characterized in that a pressing force is applied only to the center of the tip of the nail (4).

Hereinafter, modes for carrying out the present invention will be described.
(A) It is comprised from the upper surface fixing | fixed part (1) and lower surface fixing | fixed part (2), and the pressurization belt | band | zone (3) installed in the center of the upper surface fixing | fixed part (1).
(B) The width of the pressure band (3) is narrower than the width of the claw (4).
The present invention is configured as described above.
When using this, the upper surface fixing part (1) is fixed to the upper surface of the finger (5) and the nail (4), and the pressure band (3) is pressed against the center of the upper surface of the nail (4) while fixing the lower surface. The part (2) is fixed to the lower surface of the finger (5). At that time, the lower surface fixing portion (2) is moved while applying a force to the center of the tip of the nail (4) so that the center of the tip of the nail (4) is deformed downward as shown in FIG. It shall be fixed.
