Description

Technical Field

[0001] The present invention relates to a claw corrector for correcting deformed curled claws.

Background Art

[0002] A curled claw is a state in which the corner of the claw is curled inward and digs into the finger, and it often occurs on the thumb of the foot. If left untreated, pain and inflammation may occur. Therefore, instruments for correcting curled claws have been proposed.

[0003] For example, Patent Document 1 describes an invention related to a claw correction tool composed of small pieces having appropriate restoring force. It is attached to the surface of the claw that has fallen into a curled claw, and the curled claw is gradually brought back to a normal state.

[0004] Also, Patent Document 2 describes an invention related to a claw corrector composed of a correction plate adhered to the surface of the claw and a solidifying agent applied to and solidified on the surface of the claw including the surface of the correction plate. Due to the original shape restoring force of the correction plate, the claw is gradually corrected to a normal shape.

[0005] Also, Patent Document 3 describes an invention related to a deformed claw corrector in which a resin plate containing a reinforcing body made of a fibrous body along the surface direction is curved along the curved surface of the curled claw and attached with an adhesive, so that the curled claw is returned to a normal state.

Summary of the Invention

[0007] However, the ingrown toenail correction device described in Patent Document 1 has a problem with its restorative force because it is a small, flat piece. The ingrown toenail correction device described in Patent Document 2 has the advantage that the correction plate is less likely to peel off the nail during correction, but it also has a problem with its restorative force. Furthermore, the deformed nail correction device described in Patent Document 3 improves the restorative force by embedding a fibrous reinforcement along the surface direction of the resin plate, but there is a problem with the cost of forming the resin plate.

[0008] This invention solves the above-mentioned conventional problems and provides an ingrown toenail correction device that can improve restorative force at low cost. [Means for solving the problem]

[0009] To solve the above problems, the ingrown toenail correction device of the present invention is an ingrown toenail correction device consisting of a substantially rectangular plate body, the back surface of which is attached to the surface of the nail, and the plate body is curved so that the back surface is convex along the longitudinal direction.

[0010] Preferably, the plate body is curved such that its back surface is convex along the shorter direction. [Effects of the Invention]

[0011] The ingrown toenail correction device of the present invention consists of a roughly rectangular plate body, with its back surface attached to the surface of the nail. The plate body is curved so that the back surface is convex along its longitudinal direction. By curving the plate body in the opposite direction so that the back surface is concave and attaching it to the nail, the restorative force in the longitudinal direction can be improved. Furthermore, since it is formed into a curved shape without adding any special components to the plate body, it can be manufactured at low cost.

[0012] Furthermore, the curvature of the plate so that the back surface is convex along the shorter side further improves the restorative force in the longer direction.

[0013] Thus, according to the present invention, it is possible to provide an ingrown toenail correction device that can improve restorative force at a low cost. [Brief explanation of the drawing]

[Figure 2] This is an explanatory diagram (front view) showing how to use the ingrown toenail correction device. [Figure 3] This is a diagram (plan view) illustrating how to use an ingrown toenail correction device. [Modes for carrying out the invention]

[0015] Next, an embodiment of the ingrown toenail correction device of the present invention will be described with reference to Figures 1 to 3. Figure 1 is (a) a perspective view, (b) a front view, and (c) a side view showing the ingrown toenail correction device 100 according to this embodiment.

[0016] The ingrown toenail correction device 100 consists of a roughly rectangular plate 10, which can be made of resin, for example. The plate 10 has a back surface 11 and a front surface 12, and as will be described later, the back surface 11 is attached to the surface of the nail.

[0017] The plate 10 is curved such that its back surface 11 is convex along the longitudinal direction (left-right direction in Figure 1(b)). The length of the plate 10 in the longitudinal direction is not limited, but it is preferable to make it slightly longer than the width of the nail to be corrected (for example, the big toe), and can be, for example, 20 to 30 mm.

[0018] Furthermore, the plate body 10 is curved such that its back surface 11 is convex along the shorter side (left-right direction in Figure 1(c)). The length of the plate body 10 in the shorter side is not limited, but can be, for example, 5 to 10 mm.

[0019] In addition, although the degree of curvature in the longitudinal direction and the lateral direction of the plate body 10 is not particularly limited, the greater the degree of curvature, the greater the restoring force, but it becomes more difficult to attach. Conversely, the smaller the degree of curvature, the easier it is to attach, but the restoring force decreases. Therefore, it is preferable to adjust according to the shape, material, etc. of the plate body 10.

[0020] Referring to FIGS. 2 and 3, a method of using the curly nail corrector 100 will be described. FIG. 2 is an explanatory view (front view) of the method of using the curly nail corrector 100, and FIG. 3 is an explanatory view (plan view) of the method of using the curly nail corrector 100. Reference numeral 1 indicates a nail in a curly nail state, and reference numeral 2 indicates a finger (for example, the big toe of the foot).

[0021] First, as shown in FIGS. 2(a) and 3(a), the end of the back surface 11 of the curly nail corrector 100 is attached with glue (adhesive) to the side wall side end (width direction end) near the free edge (the extended part at the tip) of the nail 1 in the curly nail state. It is preferable to select the end with a stronger curl in the curly nail state for attachment. Also, it is preferable to use an activator (an activator that promotes the curing of the adhesive).

[0022] Next, as shown in FIGS. 2(b) and 3(b), glue is applied to the surface of the nail 1 to which the curly nail corrector 100 is to be attached. Then, while quickly pulling the curly nail corrector 100 in the width direction, it is attached to the side wall side end on the opposite side of the nail 1.

[0023] At this time, the curly nail corrector 100 changes from a state where the back surface 11 is curved convex along the longitudinal direction (state before use) to a state where the back surface 11 is curved concave along the longitudinal direction (the front surface 12 is curved convex) in accordance with the curved surface of the nail 1. Therefore, a strong restoring force that tries to return the back surface 11 of the curly nail corrector 100 attached to the nail 1 from a state concave along the longitudinal direction to a state convex along the longitudinal direction is generated.

[0024] Furthermore, a similar change occurs in the shorter direction of the ingrown toenail correction device 100, causing the back surface 11 to return from a concave state along the shorter direction to a convex state along the shorter direction, thereby further improving the restorative force in the longer direction.

[0025] Once the attachment is complete up to the opposite sidewall end, as shown in Figures 2(c) and 3(c), use tweezers to firmly secure the nail 1 and the ingrown toenail correction device 100 together from the free edge of the nail 1. At this time, the ingrown toenail correction device 100 will be slightly protruding outwards, making it easier to grasp.

[0026] With the above steps completed, the ingrown toenail correction device 100 is attached to the nail 1, and the ingrown condition of the nail 1 is corrected.

[0027] The ingrown toenail correction device 100 according to this embodiment consists of a substantially rectangular plate 10, and its back surface 11 is attached to the surface of the nail 1. Since the plate 10 is curved so that the back surface 11 is convex along the longitudinal direction, the restorative force in the longitudinal direction can be improved by curving the plate 10 in the opposite direction so that the back surface 11 is concave and attaching it to the nail 1. Furthermore, since the plate 10 is formed into a curved shape without adding any special components, it can be manufactured at low cost.

[0028] Furthermore, since the plate body 10 is curved such that its back surface 11 is convex along the shorter side, the restoring force in the longer side can be further improved.

[0029] Thus, the ingrown toenail correction device 100 according to this embodiment is capable of improving restorative force at a low cost.

[0030] Although an embodiment of the ingrown toenail correction device of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various other modifications are possible.

[0031] For example, in this embodiment, the back surface 11 of the plate 10 is curved so that it is convex in the short direction, but the short direction may be flat. [Explanation of symbols]
