Description

  The present invention relates to an ingrown nail correction tool that corrects an ingrown nail and a holding material for an ingrown nail correction tool that have a function of preventing peeling off from the nail.

  The ingrown nail is a disease in which the side edge of the nail plate is bent so as to be entangled inside, bites into the nail groove and the side nail cage, compresses the soft tissue of the toes, and causes pain. As the prevention jig, an ingrown nail correction tool using a shape memory alloy or a shape memory resin material disclosed in Patent Document 1 is known.

  As shown in FIG. 5, the ingrown nail correction tool 1 attaches the plate-like body 2 to the surface of the ingrown nail B of the mother A using an adhesive so that there is no gap, and lightly the entire body from above. Press and hold until the adhesive is dry and fully adhered. In such a state, when the temperature is warmed to a predetermined temperature at which a predetermined shape is stored in advance, the shape memory alloy or the shape memory resin material regains the memory and tries to restore it to a predetermined flattened or warped shape.

  Accordingly, as shown in FIG. 6, the plate-like body 2 generates a restoring force in the direction of the arrow, and the ingrown claw B is pulled so as to warp in the direction opposite to the bent shape particularly at the edge portion. By performing such a force application state for a predetermined time or repeatedly, the bending of the ingrown nail B is gradually corrected so as to become flat.

  Patent Document 2 describes an ointment in which a magnetic powder such as ferrite is mixed and magnetized to give a magnetic field to the affected area in a planar shape.

  The ingrown nail correction tool of Patent Document 1 is applied to the ingrown nail B after applying an adhesive to a part of the surface of the ingrown nail B. Or the adhesive force of the adhesive gradually weakens and easily peels off over time.

  When the plate-like body 2 is peeled off, the plate-like body 2 may be re-stretched again using an adhesive on the surface of the ingrown nail B, but the size of the plate-like body 2 is 2 mm wide, 20 mm long, The thickness is about 0.5 mm. Therefore, there is a problem that if it is peeled off, it is lost somewhere without noticing that it has been peeled off.

  Such an ingrown nail corrector is expensive because it is made of a shape memory member or a super elastic member, and if it is lost, it imposes a heavy burden on the patient.

  An object of the present invention is to provide an ingrown nail correction tool and an ingrown nail correction tool holding material that can correct an ingrown nail and prevent peeling off from the ingrown nail.

  The ingrown nail corrector according to the present invention for achieving the above object is a long plate-like body adhered to the surface of the nail plate by an adhesive, and the plate-like body is a shape memory member or superelasticity. It includes a member and a magnetic body.

  The ingrown nail corrector holding material according to the present invention is a gel-like base material to be applied to the back surface of the nail plate and is characterized in that a magnetic powder is mixed with the gel-like base material.

  According to the ingrown nail correction tool and the ingrown nail correction tool holding material according to the present invention, the magnetic substance contained in the gel-like base material and the magnetic substance contained in the ingrown nail correction tool are magnetically applied via the ingrown nail. Since it attracts, even if the adhesive strength of the adhesive is weakened, it does not peel off from the surface of the nail.

It is sectional drawing of the ingrown nail correction tool of an Example. It is sectional drawing of a mother toe and an ingrown nail. It is sectional drawing of the state which used the ingrown nail correction tool for the ingrown nail. It is a perspective view. It is explanatory drawing of a prior art example. It is explanatory drawing of a prior art example.

The present invention will be described in detail based on the embodiment shown in FIGS.
As shown in the cross-sectional view of FIG. 1, the ingrown nail correction tool 11 of the embodiment is formed as a long plate-like body having a width of 2 mm, a length of 20 mm, and a thickness of about 0.5 mm. On the upper layer side of the plate-like body is a shape-retaining material layer 11a made of a shape memory member or superelastic member as a first layer, and on the lower layer side is a magnetic layer 11b as a second layer. . The shape memory member is made of a shape memory alloy or a shape memory resin material, and the superelastic member is made of a superelastic alloy or a superelastic resin material.

  Note that the size of the ingrown nail corrector 11 can be appropriately changed according to the nail area and the like. Further, the ingrown nail corrector 11 may have a single-layer structure in which a magnetic powder such as a ferrite magnet or a neodymium magnet is mixed with a material of a shape memory member or a super elastic member.

  FIG. 2 is a cross-sectional view of the main cage A and the ingrown nail B, and a gap C is formed between the back surface of the ingrown nail B and the main cage A due to the deformation of the nail B by the ingrown nail B.

  As will be described later, the gel-like base material 12 embedded in the gap C is a holding material for holding the ingrown nail corrector 11, and a ferrite magnet or ointment 12a having medicinal components such as wounds and antibiotics. This is a mixture of powder of a magnetic body 12b such as a neodymium magnet. The ointment 12a may have no medicinal components as long as it does not affect the human body. Moreover, you may make the ointment 12a contain the adhesive component which does not harden | cure, and water resistance and durability improve with an adhesive component.

  3 is a cross-sectional view when the ingrown nail correction tool 11 and the gel-like base material 12 are used for the ingrown nail B, and FIG. 4 is a perspective view. The gel-like base material 12 is applied to the back over the entire width of the back surface of the ingrown nail B in the gap C. Since this gel-like base material 12 melts and flows to some extent in bathing or the like, it is effective to apply it after bathing.

  Next, the ingrown nail correction tool 11 is attached to the surface of the ingrown nail B on which the gel-like base material 12 is applied via an adhesive 11c. In the ingrown nail correction tool 11 including the shape memory member, since the force that warps in the opposite direction to the bent shape of the ingrown nail B by the shape memory member is not generated at the time of pasting, it can be easily pasted. It is. On the other hand, in the ingrown nail correction tool 11 including a superelastic member, a force that always warps in the direction opposite to the bent shape of the ingrown nail B by the superelastic member is generated at the time of sticking. It is somewhat difficult to do.

  However, the ingrown nail correction tool 11 including the shape memory member needs to raise the ambient temperature to a predetermined temperature by a heating means or the like in order to generate a force that warps in the direction opposite to the bent shape of the ingrown nail B. However, the ingrown nail corrector 11 including a super elastic member always generates a force that warps in the direction opposite to the bent shape of the ingrown nail B, and therefore does not need to be raised to a predetermined temperature. The nail B can be corrected quickly.

  The magnetic substance 12b of the gel-like base material 12 applied and the magnetic substance layer 11b of the stuck ingrown nail corrector 11 or the mixed magnetic substance attract each other strongly with the ingrown nail B in between. Thus, the ingrown nail corrector 11 is held.

  The ingrown nail corrector 11 affixed to the surface of the ingrown nail B has a magnetic layer 11b of the magnetic body 12b and the ingrown nail corrector 11 even if the adhesive 11c weakens with time. Alternatively, the magnetic body is held by the magnetic force, and the ingrown nail corrector 11 can be prevented from peeling off from the ingrown nail B.
