Description

  The present invention relates to a wound nail pad that is inserted between a nail and skin to relieve and treat pain.

For severe wound nails, there are surgery to remove the nails and treatment with a corrector.
Depending on the degree of mildness or the degree of progression, padded rolled cotton wool between the nails and the skin isolates the nails and the skin so that force can be applied to the fingertips during walking and exercise. Conventionally, a treatment that gradually improves by continuing the push-up state for a long time has been performed.
As an alternative to the absorbent cotton, there are various devices and inventions.
In patent document 1, it is an instrument which inserts a string-like pad between a nail | claw and skin.
In Patent Document 2, a thin plate made of metal or plastic is inserted between a nail and skin and fixed with an adhesive tape.
In patent document 3, a nail | claw is pinched | interposed and adhere | attached by the U-shaped part formed with the plastics, and also it fixes with an adhesive agent in a correction state.

JP 2004-321586 A Utility Model Registration No. 3091516 Japanese Patent No. 3393865

Since the rolled absorbent cotton is held by the pressure and friction between the nail and the skin, the sock may fall off when the pressure is weak or when the sock is attached or detached.
In patent document 1, since it is the same holding | maintenance method as the said absorbent cotton with a string-like pad, there exists a problem of dropping out similarly. In addition, the wound nail and the skin are in line contact, whereas the absorbent cotton or string-like pad isolates the nail and the skin by a substantially point contact, so the entire area where the nail and the skin are in contact can be isolated. difficult.
In Patent Document 2, since there is a hard thin plate in contact with the thin skin inside the nail, it is necessary to use it with care so that the corners of the thin plate do not contact the skin when force is applied by insertion or external contact There is.
In patent document 3, it is an effect | action which raises a nail | claw from upper part, and does not push up a nail | claw from the bottom by inserting a member between a nail | claw and skin. In addition, since it is fixed for a long time with an adhesive, it is necessary to prepare it by immersing it in hot water containing a disinfectant and drying it in advance.
The subject of the present invention is
1. It is possible to respond step by step according to the degree to which the claw presses the skin.
2. Apply a pad to the nail and skin to make the contact surface wider.
3. Ensure that the pad can be fixed stably for a long time.
4). Make the corrector plate safe to use without touching the skin.
5. It should be easy to wear, easy to wear, and easy to continue with no cosmetic problems.
Accordingly, it is an object of the present invention to provide a wound nail pad that reduces pain, normalizes walking, and improves symptoms.

[1] A sheet-like base material made of a cushioning material, an end adhesive layer provided at both ends in the longitudinal direction on one side of the base material, and a short center of the base on the same side as the end adhesive layer With a central adhesive layer provided on one side of the hand direction, a pad formed on the side facing the central adhesive layer, a release sheet adhered to the end adhesive layer and the central adhesive layer, Become a wound nail pad.
[2] A sheet-like base material, a pressure-sensitive adhesive layer provided on the entire surface of one side of the base material, a substantially rectangular shape, and the short side direction is shorter than the short side direction at the center of the base material, and the long side direction is the base material The longitudinal direction of
A pad formed shorter and one end of the pad in the short direction is the longitudinal direction of the adhesive layer
The same adhesive surface as one end in the short direction of the substantially central direction, or a part protruding from the same surface is pasted , the central adhesive layer on the side facing the same surface, and the adhesive Length of agent layer
An nail pad comprising an end adhesive layer formed at both ends in the hand direction , and a release sheet adhered to the end adhesive layer and the central adhesive layer.
[3] enclosing a straightening plate composed of a laminar piece inside the pad or form the pad into a bag shape
The wound nail pad according to [1] or [2], wherein the correction plate can be inserted from the bag-shaped opening .
[4] In a state where the wound nail pad is used, a surface opposite to the pad of the base material;
A correction plate made of a thin plate piece sized to be inserted between the nails, and the correction plate
The wound nail according to any one of [1] to [3], comprising an adhesive sheet formed in a size larger than the correction plate for holding the insertion state of the adhesive by an adhesive, and a release sheet attached to the adhesive sheet pad.

According to the wound nail pad of the present invention, claim 1 or 2 is applied to mild cases, claim 3 is applied to slightly advanced nails, and claim 4 is applied to advanced nails according to symptoms. Can respond.
By applying a pad to the nail and skin with surface contact, almost all parts of the wound nail can be isolated to reduce pain, and can be fixed for a long time with three adhesive layers, and the hard correction plate does not touch the skin and is safe Symptoms can be improved by being easy to wear and cheap and easy to continue.
According to the first aspect, by forming the sheet-like cushioning material on the base material and the pad, the material for the base material can be omitted and the manufacturing cost can be reduced.
Moreover, since the pad and the base are integrated, the strength is high, and when inserting between the nail and the skin while holding both ends with both hands, it can be inserted with force and easy to insert even if the nail is strongly compressed. The central adhesive layer plays a role of restraining the pad inserted between the nail and the skin from coming off and can be fixed for a long time.
According to the second aspect, since the pad is attached to the base material, the base material receives the hard nail, and the soft pad touches the skin to protect it.
The central adhesive layer acts as a restraint to prevent the pad inserted between the nail and the skin from coming off and can be fixed for a long time.
In the case where the pad is protruded from the same surface as the base material, the touch is good because the pad is in wide contact with the skin. Further, the correction plate of claim 4 to be described later can be further isolated so as not to touch the skin.
According to the third aspect, by providing the correction plate inside the pad, the skin can be protected by the correction plate even when the nail is strongly compressed.
The correction plate is covered with a pad and is safe without touching the skin.
Since the correction plate cannot be seen, the attached part is not conspicuous, and correction can be made without impairing the cosmetic appearance.
According to claim 4, by inserting a correction plate into the nail where the symptom is progressing, the skin is protected and the correction effect can be improved.
Further, since the correction plate is inserted between the base material and the nail, the hard correction plate can be inserted safely and smoothly without coming into contact with the skin, and can be fixed with an adhesive sheet for a long time.
