Problems to be solved by the invention

Many of the symptoms in patients suffering from nail deformities are wound nails or ingrown nails where the left or right or both sides of the nail tip or nail edge are deformed inward (finger side) and invaginated into the finger. There are spoon nails that are deformed so as to be turned outward, and the so-called nails peel off from the nail bed.

In order to restore these deformed nails to a substantially flat shape, it is necessary to know the deformation state of the nail and the cause of the deformation. For example, the nail's water retention amount, nail thickness, nail hardness, degree of deformation, From the basic information such as nutritional status, medical history, living environment, etc., it is necessary to find the external factors that promoted the deformation of the nail and find the best treatment individually.
The information that causes the deformation of the nail in this way is diverse and complex. For this reason, there are few practitioners who have analyzed the factors that deformed these nails and have acquired techniques that can be used for treatment.

The nail corrector described in Utility Model Document 1 was devised to form an arcuate nail shape ideal for playing a nail on a guitar, and is different from the present invention. There is no description about means for performing orthodontic treatment in consideration of disease symptoms such as the curved shape of deformed nails and the progress of brittleness using an orthodontic appliance.

In addition, the nail corrector has a heating temperature of about 40 ° C. to 100 ° C. in the case of a nail of a child or a woman whose nail thickness is thin, for example, according to the applicant's many experience of deformed nail treatment and earnest research. Since the nails of elderly people who have become more brittle are often thick and hard, it has been found that a heating temperature of 60 ° C. to 300 ° C. is good after moisturizing or adding water or while adding water. However, the nail corrector has a problem that the range of heat generation temperature control is as narrow as 120 ° C to 180 ° C. Further, in the case of shaping treatment from a deformed nail to a flat shape, since the nail shape changes from a curved shape to a flat shape, it is necessary to always provide stable nail heating. For that purpose, it is indispensable that the heating part plastically or elastically deforms so as to follow the shape of the nail deformation process during shaping, but this description is not disclosed either.

In addition, it is difficult to perform corrective treatment by analyzing the cause of onset of deformed nails from the experience of the shaping performed by the applicant using the pressure described in Patent Documents 2 and 3 previously proposed by the applicant. However, at present, there is a problem that only a treatment that can be corrected gradually in the long term so as not to put a burden on the nail in order to avoid it.

The present invention has been made in view of such problems. By heating the deformed nail, the side chain bond of the keratin protein involved in nail formation is denatured without using a nail softener, and the nail shape is restored. Even if there are scratches on the nail cage or nearby skin, or on nails with thin nail thickness or deformed nails that are aged and difficult to reshape, An object of the present invention is to provide a nail heating / shaping tool that can be shaped safely and in a short time without considering the deterioration state and the cause of nail deformation.

Effect of the invention

According to the invention of claim 1, the nail stratum corneum is heated by heating the nail platen side or the nail tip edge free part side of the one-side nail edge or both-side nail edge having the deformed nail using the heating element. Since the nail can be softened by denaturation, shaping by pinching using a pinching tool or a pinching tool can be promoted, and heat remaining on the shaped nail can be removed. The nail shape is fixed.
By using this action, it was possible to facilitate nail shaping using a pinching tool or a pinching tool, and to obtain an effect of safely shaping into a substantially flat shape without causing cleavage. This effect is also effective for thin and easy-to-break nails found in young people, aging-promoting thick and brittle nails, and deformed nails such as bee nails and spoon nails that were difficult to shape. It is a means, and the correspondence range to more nail deformation types has expanded. In addition, since the safety of the treatment is enhanced, the difference in the treatment result due to the difference in the technique of the practitioner can be reduced, which contributes to the improvement of the reliability of the treatment which is an anxiety factor of the patient.

According to a second aspect of the present invention, in the nail heating / shaping tool according to the first aspect, the heat conducting plate is a material having an elastic performance that enables at least the elastic region bending deformation resembling the curved shape of the deformed nail. By having the shaping action by the elastic restoring force of the heat conducting plate, the self-shaping ability by the shaping tool itself was obtained. That is, the heat shaping operation can be completed by attaching the shaping tool on the nail plate surface along the nail plate shape of the deformed nail. This eliminates the need for a clamping tool or the like for obtaining a clamping pressure, and has an effect that simplification of the tool and provision of simple treatment means.

Yes. As a result, the deformed nail either left or right in the nail width direction is heated while acting from the substantially nail width direction center of the nail tip edge portion or nail tip edge free portion of the deformed nail inserted into the nail insertion gap. By sliding to the edge, the claw is shaped into a substantially flat shape. In addition, when the nail | claw deformation | transformation has developed to the right-and-left both edge edge, it shape | molds using the method similar to the above-mentioned also about the nail edge which has not finished shaping.
The shaping means using the shaping tool includes inserting the flat portion at the front edge of the front nail of the nail into the nail insertion gap, and then applying nipping pressure to the nail edge where the deformation of the nail is strengthened. By sliding sideways while maintaining the heating and clamping pressure, an effect that can be gradually shaped into a flat shape is obtained. Due to this effect, even if the nail has a deep curved deformation, the moving part of the shaping tool is heated and softened sequentially, so that it can be flexibly shaped into a flat shape even for forced deformation due to pinching. It can provide gentle and safe shaping that prevents

According to the fourth aspect of the present invention, the self-temperature control type heating element or any substantially constant heat generation designed at an appropriate temperature from between 40 ° C. and 300 ° C. which is the heat generation temperature considered from the nail quality and the degree of nail deformation.

In addition, by providing the heating temperature control device that can heat at an arbitrary constant temperature, safety corresponding to individual nail quality and stable heating shaping can be achieved, and treatment data of the practitioner It can be collected and contributes to the promotion of treatment technology.

According to the invention of claim 5, there is provided a storage container that is provided on the nail contact surface side of the heat conducting plate and contains a water retaining material that impregnates water or an aqueous solution for softening the nail. The nail contact surface is made of a material that has vapor permeability, so that fragility is promoted due to aging or deterioration of nail deformation, nail with thick nail disease, and nail whose deformation has deteriorated. However, since the liquid stored in the storage container is heated by the heating element, the liquid can be impregnated into the nail without inhibiting the heating of the nail. This facilitates the breaking of hydrogen bonds in the keratin protein that composes the nail without being affected by the liquid temperature or the outside air temperature environment to be treated, the nail is sufficiently softened, and can be promoted to a nail quality that is easy to treat, The effect of performing heat shaping safely while preventing cleavage and splitting is obtained. Moreover, even in the case of the nail where the embrittlement cannot be visually confirmed, there is an effect that the safety at the time of shaping can be ensured.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described with reference to FIGS. In addition, embodiment is not limited to the following forms, Other aspects can also be implemented if the subject of this invention can be solved.

An embodiment of the nail heating shaping tool 10A according to claims 1 and 4 of the present invention will be described with reference to FIGS.
As shown in FIG. 1A, the aluminum heat conduction plate 1 of the nail heating shaping tool 10A is covered with a flexible silicone rubber sheet-like covering, insulated, waterproof protected, and sandwiched. A PTC characteristic self-temperature control heater 2 (hereinafter referred to as a PTC heater) having a lid made of an aluminum casing that can withstand the applied pressure and having a maximum heat generation temperature of 100 ° C. is in close contact.
The operation in the above configuration will be described. When the PTC heater 2 provided in the shaping tool 10A attached to the nail plate side and the nail tip edge side of the deformed nail generates heat, the heat conduction plate 1 made of aluminum and having good heat conduction is heated. It is done. Since this PTC heater 2 is a self-temperature control type, it does not generate heat above the maximum temperature of the self-heating design, and even if an accident such as an overcurrent occurs for some reason during the treatment, temperature rise is suppressed. Therefore, there is no danger and safety is high. Although not described, if there is a possibility that the finger skin is burned by heating of the heating element, it is made of resin, elastomer, silicon, ceramic, mineral, or glass fiber that can protect the finger skin from heat. You may provide the heat insulating material suitably selected from the inside in this heat generating body side which contacts a finger meat at least.

Next, the operation in the orthopedic operation will be described with reference to FIG. 1B of the wearing example. The adhesive is applied so as to be extended on the nail back surface side of the deformed nail 21 at the nail tip edge and in the direction of both nail edges. The nail heating / shaping tool 10A adhered using the The deformed claw 21 to which the heat conducting plate 1 adheres is heated and heated by the heat conducting plate 1 to which heat is conducted by the heating of the PTC heater 2. 2. While being heated, it is shaped into a substantially flat shape by clamping with a clamping tool. In addition, when pinching, you may apply by the continuous contact in the same position of time suitably, or a gradual continuous or intermittent movement to a deformation | transformation nail edge along a nail | tip tip edge. 3. After the clamping operation is finished, the nail heating / shaping tool 10A is removed immediately, and the heat remaining on the deformed nail 21 is removed, and the nail is fixed in a substantially flat shape, and the deformed nail is shaped. In addition, you may apply | coat fixing agents, such as normal temperature polymerization acrylic resin, to a nail | claw back surface for the deformation | transformation recurrence prevention of a nail | claw after completion | finish of a shaping process. In addition, as for the time of the clamping pressure by setting the heating temperature, it is preferable to apply a contact time of about several seconds when the temperature is 180 ° C. or higher, and about 10 minutes when the temperature is about 40 ° C. Moreover, when setting the temperature and time to heat by means other than the above, it is good to carry out within the heat denaturation reversible region of the keratin protein which forms a nail | claw. In addition, when high-temperature heating is performed or when the nail is deficient in moisture, such as a dry nail, lanthionine that makes it difficult to form a flat shape by impregnating the nail with weakly acidic water before shaping. Inhibiting the formation of bonds can provide stable shaping.

A nail heating and shaping tool 10B, which is another example of the nail heating and shaping tool 10A according to claims 1 and 4 of the present invention, will be described with reference to FIG.
The nail heating / shaping tool 10B shown in the perspective view of FIG. 2 includes the sandwiching portions 3 and 4 that the heat conducting plate 1 faces vertically and the coupling portion 6 that connects the top and bottom sandwiching portions. Therefore, a means that can be inserted into the deformed claw 21 by plastic clamping is provided.
The nail heating shaping tool 10B is appropriately selected and used from metals or polymer compounds having plastic performance. In the practice of the shaping tool 10B, aluminum that can be deformed in a plastic region by using a clamping tool. Using a rectangular flat plate made of metal, the upper part 3 for sandwiching and the lower part 4 for sandwiching which are bent from the coupling part 6 so as to face each other and have a substantially U-shaped cross section in the short direction are opposed to each other. Further, a nail insertion gap 5 is formed into which a deformed claw 21 formed by the upper and lower sandwiching portions 3 and 4 facing each other can be inserted. A covered PTC heater 2 is fixed to the upper side of the sandwiching upper portion 3 so as to be in close contact therewith. With these configurations, the nail heating shaping tool 10B is formed.
The shaping tool 10B is characterized by the fact that the upper part 3 for clamping and the lower part 4 for clamping always face each other when the claw 21 is pressure-shaped by plastic working the connecting part 6 in the crushing direction. The connecting portion 6 functions as a restricting means for restricting the shift to the left and right as much as possible. This made it possible to perform clamping pressure shaping using a general-purpose clamping tool.
The shaping means heats the nail 21 for an appropriate time from the state in which the nail 21 is inserted into the nail insertion gap 5, and clamps the upper and lower clamping parts 3 and 4 into a plastic region. . During the clamping process, the upper and lower clamping parts do not shift from side to side due to the action of the restricting means of the coupling part 6, and the clamping pressure can be provided in a stable manner, so that no special tools or techniques are used. It has the effect of being able to heat and shape the various deformed nails into a substantially flat shape that is safe and always stable.

The heat conducting plate 1 has Ti-Ni (Ni concentration of about 56 wt%, Ni elastic capacity) that enables elastic deformation so as to imitate the curved shape of the deformed claw 21 that has been deformed in the claw width direction. Heat treatment (approx. 500 ° C.) is made of a super elastic alloy material, is formed in a substantially rectangular flat plate size that can be installed in the right and left nail contour direction, and is covered with a silicon rubber sheet protective covering so as to be in close contact with the upper part of the heat conduction plate The nail heating shaping tool 10C is configured by fixing and installing the mounted 45 ° C. self-temperature control type PTC heater.
The shaping means fixes the rectangular heat conduction plate 1 in the nail width direction on the nail plate so as to be laid on both side edges of the nail width direction on the nail tip side, and then is approximately 45 ° C. The deformed claw is heated by the designed PTC heater. When it is confirmed that the claw softened by heating has progressed to a flat shape due to elastic stress, the heater is turned off and the residual heat of the claw is dissipated to fix the claw shape.

The nail heating shaping tool 10D according to the third and fourth embodiments of the present invention will be described with reference to FIG.
In the nail heating / shaping tool 10D shown in FIG. 3 as an example, a rectangular flat plate made of stainless steel appropriately selected from elastic materials is used to be bent from the coupling portion 6 so as to face each other, and the upper side for sandwiching A sandwiching clip having a substantially U-shaped cross section in the short direction is formed by the portion 3, the coupling portion 6, and the sandwiching lower side portion 4 constituting the heat conducting plate 1. Further, the nail contact surfaces of the sandwiching upper part 3 and the sandwiching lower part 4 form a smooth surface, and the deformed claws 21 have curved inner sides at both ends in the nail width direction of the sandwiching upper part 3. A tongue-like smooth curved surface 7 is formed so as to be along the peripheral surface side, and the nail contact surfaces of the upper and lower sandwiching portions 3 and 4 are opposed to each other to form the nail 21. The nail insertion gap 5 has a gap height that can be sandwiched. Further, the nail heating and shaping tool 10D is configured by fixing the covered PTC heater 2 in close contact with the outer surface of the sandwiching upper portion 3 and at least a portion in contact with the nail deformation surface.
The feature is that shaping can be performed without using a special tool such as a clamping tool or a clamping tool.
The shaping means inserts the nail width direction center of the nail tip edge free portion of the nail 21 into the nail insertion gap 5 and then nipping the nail 21 to the nail edge where the deformation of the nail 21 is strengthened while applying heating nipping pressure. By laterally moving in a state where the pressure is maintained, an effect of shaping the deformed portion of the nail that is located for each movement is obtained.
