Wound patch structure for treating wounds caused by ingrown toena

The present invention relates to a wound patch structure for treating wounds caused by ingrown toenails. More particularly, the present invention relates to a wound-attached structure for treating a wound caused by ingrown nails, which is attached to the hands and feet along the side of the nail (side line of the nail). The structure comprises: (i) a region of the wound abutment portion, a soft surface for intimidating the wound for adhering to the wound caused by the ingrown toe; and (ii) a guide region having a chute for The side of the nail piece is accommodated and slides along the side of the nail piece in the length direction of the hand and nail, and the wound patch structure has a rod pattern, and the sliding groove spans the front end of the wound patch structure At least a portion of the distance to the rear end portion is extended in the longitudinal direction of the wound patch structure, and in a state where the wound patch structure is attached to the hands and feet, the structure will be located at the root of the hands and feet The end of the body is defined as its front end portion, and the end of the structure at the front end of the hand and foot is defined as its rear end portion, and when the wound sticker structure is mounted on the hands and feet, the wound is closely attached. The soft surface used is guided to the inlay Position caused by trauma. When the wound patch structure of the present invention is used, the connection between the wound abutment region and the guide portion region is independent of the degree of incarceration deformation or the severity of wound pain caused by ingrown nails, and is not only the front end of the hand and foot nails. The ingrown nail trauma can also accurately treat the ingrown nail wound near the root of the hand and foot nail which is difficult to effectively and efficiently treat in the prior art, thereby effectively and effectively treating the wound caused by the ingrown nail. In addition, the traumatic pain caused by the ingrown nail can be alleviated faster (i.e., the immediate treatment is performed). Further, the wound patch structure of the present invention exerts the effect of correcting the ingrown nail by pushing up the side of the nail piece (the side edge of the hand and nail) and exerting the effect of correcting the ingrown nail.

The deformation of the nail usually refers to the armor or inlay. Although the term is used indiscriminately, the general nail is a symptom in which the nail is inwardly wrapped in the direction of the nail, and the ingrown nail is a symptom of the severely bent nail entering the skin and the meat tissue at both ends. In the present invention, the symptoms of deformation of the hands and feet that cause trauma and pain to the patient's hands and feet are collectively referred to as inlays, unless otherwise specified. In the case of ingrown toenails, as the nail grows, the side edges of one or both sides of the nail penetrate deep into the nail groove, thereby compressing the soft tissue (the meat inside the nail) causing inflammation and causing pain or colic . When the ingrown nails are severe, the inflammation is the roots that enter the hands and feet, making the pain more intense. The main causes of the disease are compression, trauma, deep cut, and congenitality when cutting nails. The incidence of ingrown toes, especially the big toes, is higher. In particular, the incidence of ingrown in the thumb of the big foot is higher. In order to treat ingrown toenails, conventional methods are surgical methods to remove lateral edges of the nails that are trapped in the nail sulcus, and methods using orthotic tools or orthotic devices. For a method of using a correction tool or a correction device, reference is made to U.S. Patent No. 4,057,055 (Patent Document 1), JP-A-8-215227 (Patent Document 2), and JP-A-2001-276104 (Patent Document 3). JP-A-2011-104231 (Patent Document 4), JP-A-2002-360619 (Patent Document 5), WO2008-142880 (Patent Document 6), and Patent No. 55,997,913 (Patent Document 7).

However, the method of surgery is complicated, and in addition, the width of the surgical nail piece is permanently narrowed. In addition, in the surgical method, since the nail entering the soft tissue is partially cut and removed, bacterial infection may be caused. In addition, the nail is partially removed by surgery, and even if the nail is temporarily treated, it cannot be corrected. The nail is wrapped around the entire direction of the nail, so most of the ingrown nails will recur after surgery. Therefore, the method for treating ingrown nails is preferably a method which is preferably not subjected to surgery, that is, a conservative method.

In the method using the correction tool or the correction device described in Patent Documents 1 to 7, the ingrown nail (deformed nail) can be preferably treated. However, the methods in Patent Documents 1 to 7 do not directly exert a therapeutic effect on wounds caused by ingrown toenails. Therefore, the methods in Patent Nos. 1-7 are incapable of effectively and efficiently treating wounds caused by ingrown nails, and in addition, pain cannot be alleviated faster and more (i.e., immediate treatment cannot be performed).

As a conventional method for treating wounds caused by ingrown nails, a method of applying a wound to the wound, or using an elongated metal body or a resin body to cover the side edges of the inlay (side of the nail piece) Method etc. For a method of applying the wound to the wound caused by the ingrown nail, reference is made to JP-A-2012-125527 (Patent Document 8) or JP-A-2013-81723 (Patent Document 9). For a method of covering the side edge of the inlay with an elongated metal body or a resin body, reference is made to JP-A-2004-329646 (Patent Document 10) or US Patent Application Publication No. US2007/0287945a1 (Patent Document 11). .

The wound patch used in the method described in Patent Document 8 or Patent Document 9 has a position different from that of the old wound except for the mat (the portion for wound recovery) that contacts the wound, and other common wounds of the old wound. Essentially have the same construction. As shown in the drawings shown in Patent Document 8 or Patent Document 9, when the method described in Patent Document 8 or Patent Document 9 is used, the wound at the position near the front end of the nail can be treated, but the vicinity of the nail base cannot be treated substantially. Trauma. As described above, when the ingrown nails are severe, the inflammation spreads to the roots of the hands and feet, making the pain more intense. Therefore, it is in fact impossible to treat the wound near the root of the ingrown nail, which means that the wound caused by severe ingrown nails is substantially incapable of treatment. Therefore, according to the method described in Patent Document 8 or Patent Document 9, the wound caused by the ingrown nail cannot be effectively and efficiently treated, and in addition, the pain cannot be relieved quickly and greatly (that is, the immediate treatment cannot be performed). .

Patent Document 10 (JP-A No. 2004-329646) proposes an ingrown-type treatment tool having a C-shaped cross-sectional shape formed of a hard material. The ingrown-aid treatment tool is mounted on the hands and feet to embed The side edge of the nail enters into the interval of the C-shaped cross-sectional shape. When the ingrown-type treatment tool is attached to the hand and foot fingers, since the side edge of the armor is covered by the tube body, the wound caused by the ingrown nail is mild At this time, the pain of the wound is reduced after a period of time. However, the ingrown-type treatment tool of Patent Document 10 does not have a structural feature for actively treating the wound caused by the ingrown nail, and therefore is not intended to be severe. The wound caused by the ingrown nail exerts a direct therapeutic effect and is substantially incapable of treating the wound caused by the severe ingrown nail. Therefore, even if the ingrown-type treatment tool of Patent Document 10 is used, it cannot be effectively and efficiently treated. Injury caused by ingrown nails, in addition, can not ease the pain more quickly, that is, can not be treated immediately.

The point of the method described in Patent Document 11 is that the side wall of the nail that is in close contact with the side edge of the nail is pressed side by hand with the finger and the foot, and the side edge and the wound portion of the armor are exposed, and then the elongated soft body having a U-shaped cross section is used. A resin sheet (a material called "protecting gutter") covers the side edges of the inlay, whereby the side edges of the inlay and the wound portion are spaced apart from each other to promote healing of the ingrown nail. However, in this case, first of all, in the case of severe ingrown toenails, due to severe inflammation, the surrounding area of the wound is quite swollen and very painful. Therefore, the fingers and the fingers will be close to and pressed against the side edges of the inlay. The side wall of the nail is pressed to the side with a large pain. In addition, when the nail side wall is pressed to the side as described above, the exposed space is very narrow, it is difficult to secure a sufficient space, and pus or lymph is oozing out, and in most cases, it cannot be confirmed by observation, and therefore, even if it is skilled The operator does not allow the soft resin sheet to be properly worn across the entire length of the side edge of the armor (when viewed in the longitudinal direction of the hands and feet). In addition, as described above, when the ingrown toe is severe, the inflammation spreads over the roots of the hands and feet, making the pain more intense. In addition, the roots of the hands and feet are covered by the back wall of the nail (independent of whether it is invisible or not). Therefore, in the method described in Patent Document 11, the soft resin sheet is substantially incapable of covering the side edge of the inlay with the soft resin sheet at the root of the hand and foot fingers. Therefore, it is practically impossible to treat the wound near the root of the hand and the foot (severe The wound caused by ingrown nails is treated. Therefore, with the method of Patent Document 11, the wound caused by the ingrown nail cannot be effectively and efficiently treated, and in addition, the pain cannot be alleviated quickly and greatly (that is, the immediate treatment cannot be performed).

Problem to be solved by the invention

As described above, in the known method using a correction tool or an orthodontic device (method for correcting ingrown nails), since a direct therapeutic effect cannot be exerted on a wound caused by ingrown nails, it cannot be effectively and efficiently treated. Trauma, and can not ease the pain faster and more. Further, as described above, a known method of applying a wound patch to a wound for treating a wound caused by ingrown nails, or a known method of covering an armor side edge using an elongated metal body or a resin body, is substantially impossible. Treatment of wounds near the roots of the hands and feet (trauma caused by severe ingrown toenails), therefore, the wound cannot be effectively and efficiently treated, and the pain cannot be alleviated faster and more. Therefore, in order to solve the problems of the above-mentioned prior art, there is a need for a treatment tool or a treatment method which is not related to the degree of deformation of the hands and feet or the pain severity of the wound caused by the ingrown nails, not only the ingrown nail wound at the front end of the hand and foot nails, but also It can accurately treat the ingrown nail trauma near the root of the nails of the hands and feet which is difficult to effectively and efficiently realized in the prior art, thereby effectively and effectively treating the wound caused by the ingrown nails, and more quickly and greatly easing the inlay. Wound pain caused by A (ie, implementation of immediate treatment). In general, regardless of the severity of the ingrown toe, and regardless of the position of the incisor caused by the wound in the length of the hand and nail, it is necessary to develop an exact and immediate effect on the trauma and pain caused by the ingrown toenails. Therapeutic techniques.

For example, the expanded portion 1E may be tapered or formed of a sheet, and a portion that is in close contact with the finger of the hand has a viscous surface.

5a is a schematic partial cross-sectional view and a schematic partial cross-sectional view of FIG. 5b, and a schematic partial cross-sectional view of FIG. 5c, although both the wound abutting portion region 2 and the guiding portion region 3 are shown, but for the treatment of ingrown toe In the wound, the soft surface 2A for the wound adhering to the wound-adhering region 2 can be attached to the wound site Fi to be treated. Therefore, in the state in which the wound patch structure of the present invention is attached to the hands and feet, the wound abutment region 2 and the guide portion region 3 can be displayed in all the sections across the longitudinal direction of the hands and feet and the hand and foot nails. Both parties, but not required, can show either party. For example, in the aspect shown in FIG. 1a, in the entire length between the front end portion 1A to the rear end portion 1B of the wound patch structure, both the wound abutment portion region 2 and the guide portion region 3 are extended, and therefore, When the wound patch structure shown in Fig. 1a is mounted on the hands and feet, in all the sections across the length direction of the hands and feet and the hand and foot nails, the wound abutment area 2 and the guide area are necessarily displayed. 3 both sides. Further, for example, in the aspect shown in FIG. 1c, although the wound abutment portion region 2 exists in the intermediate portion between the front end portion 1A and the rear end portion 1B of the wound patch structure, the guide portion region 3 does not exist, so When the wound patch structure of the aspect shown in FIG. 1c is mounted on the hands and feet, only the wound abutment region 2 is shown in the cross section of the intermediate portion in the direction of the length direction of the hands and feet and the fingernails. . Further, for example, in the aspect shown in FIG. 1i, although the guide portion region 3 exists in the intermediate portion between the front end portion 1A and the rear end portion 1B of the wound patch structure, there is no wound abutment portion region 2, Therefore, when the wound patch structure of the aspect shown in Fig. 1i is attached to the hands and feet, only the guide portion region 3 is shown in the cross section of the intermediate portion in the direction of the longitudinal direction of the hands and feet and the hand and nail.

In the wound patch structure of the present invention, preferably, the wound adhering portion region 2 is formed of a soft body, and the guide portion region 3 is formed of a hard body. An example of a soft body for the wound-adhering portion 2 can be obtained from a hydrogel, gauze, woven fabric, non-woven fabric, cotton wool body, rubber body, foamed polyurethane body, sponge body, fibrous body, and high flexibility. The resin body and the group of the material body which absorbs or stores the body fluid through the porous structure and/or the uneven structure are selected. Further, an example of the hard body used for the guide portion region 3 can be selected from the group consisting of a resin body having low flexibility, a metal body having low flexibility, a hard pulp body, a glass body, a stone body, and a ceramic body.

Hereinafter, the materials constituting the wound patch structure of the present invention will be described in detail.

The soft surface 2A for wound adhesion of the wound adhering portion region 2 is in close contact with the wound portion of the hands and feet caused by the ingrown to exert a healing promoting effect and/or a therapeutic effect. In the present invention, the "soft surface" may be replaced with "a surface for exerting a healing promoting effect and/or a therapeutic effect". Therefore, the material constituting the wound adhering portion region 2 is usually a wound patch or a medical pad or the like, and preferably has at least the same degree of flexibility, flexibility, or softness as the wound restoring material (blending material). Or air cushioning, or body fluid absorption and storage (in the present invention, body fluid absorption and storage means having the property of absorbing or storing body fluids). For the purpose of the present invention, although the material constituting the wound adhering portion region 2 is not particularly limited, it is generally preferably soft. In the present invention, softness means having at least one property selected from the group consisting of flexibility, flexibility, softness, air cushion property, body fluid absorption, and storage property, and is closely attached to the hands and feet caused by the inlay. The body of the wound that is used to exert a healing effect and/or a therapeutic effect. A material body that is effectively used as a wound healing material (conditioning material), such as a wound patch or a medical pad, can be used as a soft body in the present invention. Examples of preferred materials for the wound abutment region 2 are: hydrogels, gauze, woven fabrics, non-woven fabrics, absorbent cotton bodies, rubber bodies (natural rubber and synthetic rubber), polyurethane bodies, foamed polyurethane bodies, Sponge (natural sponge and artificial sponge), resin body (highly flexible monomer made by plant fiber or other fibers), fibrous body, plant fiber body, resin fiber body, glass fiber body, carbon fiber body A metal fiber body, a resin body having high flexibility, and a metal body having high flexibility. The other material of the preferred soft body may be a body material having a porous structure and/or a body fluid absorption and storage property of a concavo-convex structure (small groove or the like). A material having body fluid absorption or storage is usually a body of material exhibiting capillary action.

Here, the above-mentioned soft body may be used singly or in combination of a plurality of materials. For example, the wound abutment portion 2 may have a laminated structure composed of at least two of the above soft bodies, and the outermost layer may provide a soft surface 2A for wound adhesion. The thickness of each layer in the laminated structure as the wound adhering portion 2 is generally in the range of 0.01 to 10.0 mm, preferably 0.05 to 5.0 mm, more preferably 0.1 to 3.0 mm. In order to achieve the object of the present invention, the wound abutment portion 2 may be a non-porous structure or a perforated structure. The wound adhering portion region 2 and the soft body for the wound adhering portion region 2 may be a porous structure and/or a concavo-convex structure (small groove or the like). Further, it is possible to provide body fluid absorption and storage properties based on a porous structure and/or a concavo-convex structure (such as a fine groove). Details of the porous structure and the uneven structure will be described below.

The soft body used in the wound-adhering area 2 preferably has the characteristics of body fluid absorption or storage, thereby improving the softness and adhesion to the wound, and protecting the wound in a moist environment, thereby improving the wound. The healing effect of the wound. In order to impart a characteristic of body fluid absorption or storage to the soft body, for example, the soft body may be a material body having a capillary phenomenon or a material body having a highly absorbent molecular structure.

Examples of the material body having a capillary phenomenon are: a porous structure, a textured structure (for example, a structure having a single or a plurality of fine grooves), a fibrous body, a fiber aggregate, a woven fabric, a nonwoven fabric, a mesh Body and so on. An example of a porous structural body as a material body having a capillary phenomenon is a foamed polyurethane body, and an example of a suitable wound healing material (conditioning material) which is sold with a foamed polyurethane body is: a polyurethane foam which is generally used in the medical industry. , reconciliation materials, the well-known products. For example, "Hydrosite" (registered trademark) of the Japanese corporation of Smith & Nephew, UK. Further, an example of a suitable wound restorative material to be sold which contains a porous structural body composed of a synthetic resin and cellulose (specifically, a mesh sheet and a nonwoven fabric sheet) may be Plusmoist (registered trademark) of Teikoku Corporation of Japan.

A material body having a highly absorbent molecular structure is widely used in the medical industry, and is referred to as a "hydrogel" for convenience in the present invention. In the present invention, the term "hydrogel" may mean any polymer having a molecular structure having hydrophilicity and/or water absorption used in the formation of a wet environment in "wet therapy". The hydrogel body is superior in terms of its ability to safely absorb or store water or body fluids (i.e., the ability to safely absorb or store large amounts of water or body fluids). The hydrogel body has the property of swelling by water or body fluid. Further, the hydrogel body has a high swelling ratio of about 110 to 1,000% (the value of the swelling ratio is calculated according to the following formula: (volume after gel swelling/volume before gel swelling) x 100). Since the swelling ratio (%) of the hydrogel body is high, when the hydrogel body is used in a state where the wound adhering portion region 2 is not swollen, even when the wound patch structure 1 is attached to the hands and feet, the wound is tight. The thickness of the patch portion 2 is small, and the body fluid can be swollen after installation, so that the volume is greatly increased and the tightness of the wound is improved. In addition, the side of the nail piece (the side edge of the hand and foot) is pushed up to improve the effect of correcting the inlay. The hydrogel body is excellent as a material for the wound abutment region 2 from the viewpoint of providing an ideal moist environment to improve the wound healing effect.

When the hydrogel body is used as the material of the wound adhering portion region 2, the method or aspect to be used is not limited and can be appropriately selected. For example, the hydrogel body as the wound adhering portion region 2 may be in a state of not swelling or may be in a swollen state before the wound patch structure 1 is attached to the hands and feet. When the hydrogel body as the wound adhering portion region 2 is used, the above-described thickness range of the wound adhering portion region 2 means a value after swelling.

Before the wound patch structure 1 is attached to the hands and feet, the hydrogel body as the wound abutment region 2 is in a state of no swelling, at which time the wound abutment region 2 may not actually have a wound The surface of the soft surface 2A is adhered to, but after the wound-attached structure 1 is attached to the hands and feet, the hydrogel body swells the body fluid, so that the soft surface 2A for wound adhesion can be sufficiently formed. . Therefore, in the present invention, before the wound-attached structure 1 is attached to the hands and feet, the soft surface 2A for the wound-adhesive portion of the wound-adhering portion 2 is not necessarily present, and the wound-attached structure 1 can be Generated after mounting on the hands and feet. At any time before and after attaching the wound patch structure 1 to the hands and feet, in order to swell the hydrogel body as the wound adhering portion region 2, a body fluid may be used, or an aqueous liquid other than the body fluid may be used, and also Non-aqueous liquids such as ethanol can be used.

Hydrogels are commonly used in wound healing materials (blending materials) such as wound stickers or medical pads. An example of a hydrogel that is suitable for medical use is a well-known product that is commonly used as a "hydrocolloid, blending material" in the medical industry. For example, "Duoactive" (registered trademark) manufactured by Nippon Corporation of the US company ConvaTec, Denmark "Comfee" (registered trademark) manufactured by the Japanese corporation of Coloplast A/S, "Tegaderm" (registered trademark) manufactured by the Japanese company of 3M, and "Absocure" (registered trademark) manufactured by Nitto Medical Co., Ltd., Japan ). Other examples of commercially available hydrogels for sale are: the well-known products of the medical industry as "hydrogenated polymers, blending materials", for example, "Tielle" manufactured by the Japanese company Johnson & Johnson, Inc. (registered) trademark). Other examples of commercially available hydrogels for sale are: the medical industry is commonly known as a "fibrous blending material" or a "waterborne fiber blending material", for example, the Japanese company of the British company Smith & Nephew "Durafiber" (registered trademark). Other examples of commercially available hydrogels for sale are: the medical industry is commonly known as a "hydrogel, blending material", for example, the "Intrasite Conformable Dressing" of the Japanese company Smith & Nephew's Japanese corporation. Trademark). Other examples of hydrogels suitable for medical use are: the well-known products of the medical industry as "alginate blending materials", for example, "Kaltostat" (registered trademark) of the Japanese company ConvaTec, Japan, and Japan "Sorbsan" (registered trademark) manufactured by ALCARE (the above-mentioned medical medical gels listed, except for "Intrasite Conformable Dressing" (registered trademark), which are not swollen in the initial state, and are applied to After trauma, the wound-infiltrated body fluid swells. "Intrasite Conformable Dressing" (registered trademark) is a blending material that impregnates a water-swellable hydrogel (gel-like) into a non-woven gauze, that is, in an initial state. The type of swelling.

In order to achieve the object of the present invention, the shape of the wound abutment portion 2 is not particularly limited. However, in general, for example, it may have a shape similar to that of the wound abutment region 2 shown in Figs. 3a - 3r. After the wound patch structure of the present invention is attached to the hands and feet, the wound abutment region 2 and the guide portion region 3 are in a state in which the respective properties can be exerted. For example, the wound abutment region 2 can cover all of the guide portion region 3. (Refer to Figure 3o and Figure 3p). Further, for example, the wound abutment region 2 may be used to cover an outer edge portion or a part or all of the portions in the guide region 3, or the like, or may be installed when the wound patch structure of the present invention is attached to the hands and feet. Thereafter, only part or all of the portion that may come into contact with the flesh (soft tissue) of the hands and feet at a relatively sharp angle is covered (refer to FIG. 9). The method of preparing the wound abutment region 2 is not particularly limited. A known processing method can be appropriately selected depending on the material used or the desired shape. An example of a known processing method is that in the case of using a resin, shaping (ejection setting, compression setting, etc.), bending, mechanical processing, laser processing, or the like can be used. In the case of using a ceramic material, a method of sintering into a desired shape, mechanical processing, laser processing, or the like can be used. In the case of using a metal, a known method (simulation model method, punching method, casting method, forging method, mechanical processing, laser processing, powder metallurgy method, etc.) can be used.

The thickness of the guide portion region 3 is 0.5 mm (the type of the hydrogel sheet used is such that it does not swell in the initial state, and is applied to the wound site, and is wounded. The infiltrated body fluid swelled. Aron alpha A "Sankyo" (registered trademark), a medical adhesive manufactured by Japan East Asia Synthetic Co., Ltd., was used to bond the wound-adhered area 2 and the guide portion 3 to each other. The dimension measured in the longitudinal direction is 10 mm. The dimension (including the handle 1C) measured according to the direction across the length direction of the wound patch structure is 14 mm, and wherein the size of the portion having the i-invasion region 2 is It is 8 mm.

2. The treatment method inserts the front end portion of the wound patch structure from the front end of the nail and the nail along the side of the nail piece, and slides the chute 3A along the side of the nail piece toward the root of the hand and nail, thereby bringing the wound to the area of the wound. The soft surface 2A of the wound snug is guided to the wound position caused by the inlay. The entire wound structure can penetrate deeper than the free edge of the hand and foot. Then, an adhesive (Aron alpha A "Sankyo" (registered trademark)) manufactured by Japan East Asia Synthetic Co., Ltd. is placed between the guide portion region 3 and the handle 1C and the upper surface of the hand and nail to bond and fix the wound patch structure. The upper surface of the fingernails. The above-described mounting operation was performed on the first treatment day, and the wound patch structure was removed 7 days after the first treatment day (the second treatment day), and the above-described mounting operation was performed again, and the wound patch structure was replaced. Six days after the second treatment day, the patient's wound-attached structure naturally fell off during bathing, and the inventors found that the toes were completely cured the next day (after 7 days of the second treatment day).

3. Specific Description of Healing Passage A photograph of the toe before the treatment (installation of the wound patch structure) on the first treatment day is shown in Figs. 14a and 14b. It was confirmed to have large granulation, redness, swelling, and pain, and it was difficult to walk. A photograph of the toes after the treatment (installation of the wound patch structure) on the first treatment day is shown in Figs. 15a and 15b. After the wound-attached structure was installed, the pain subsided immediately and the walking improved. Fig. 16a and Fig. 16b show photographs of the toes before the treatment (exchange of the wound patch structure) in the second treatment day (after 7 days of the first treatment day). At this point in time, about 80% was cured, the pain disappeared and walked normally. Fig. 17a and Fig. 17b show photographs of the toes after the treatment (exchange of the wound patch structure) in the second treatment day (after 7 days of the first treatment day). A photograph of the toes 7 days after the second treatment day is shown in Figs. 18a and 18b. Completely cured except for about swelling. Therefore, it can be estimated that after 2 to 3 days of the second treatment day (that is, 9 to 10 days after the first treatment day), it is completely cured.

[Embodiment 2]

The invasive nail wound was performed by the same operation as the first treatment day of Example 1 with the same wound patch structure as in Example 1 for a 20-year-old female patient (the first toe on the left side had an inlay) treatment. Seven days after the treatment day, the inventors confirmed that the toes were completely cured.

(Specific Description of Cure Passing) A photograph of the toe before the treatment day (installation of the wound patch structure) is shown in Figs. 19a and 19b. It was confirmed to have obvious pain, internal bleeding, inflammation, and granulation, and it was difficult to walk. A photograph of the toes after the treatment of the day of treatment (installation of the wound patch structure) is shown in Figures 20a and 20b. After the wound-attached structure was installed, the pain subsided immediately and the walking improved. A photograph of the toes before removal of the wound-attached structure after 7 days of the treatment day is shown in Figures 21a and 21b. A photograph of the toes after removal of the wound-attached structure after 7 days of the treatment day is shown in Figures 22a and 22b, completely cured.

[Example 3]

The invasive nail wound was performed by the same operation as the first treatment day of Example 1 using the same wound patch structure as in Example 1 for a 27-year-old female patient (the first toe on the left side had an inlay) treatment. However, the patient of Example 3 uses a symmetrical shape (that is, has a mirror-symmetric relationship) because both sides of the nail piece on both sides of the left toe (the side edge of the nail) have a wound on both sides. Two (a pair of) wound-flap structures of the shape). The pair of wound patch structures are mounted on both sides of a toe and bonded and fixed to the upper surface of the toenail using an adhesive, and at this time, the handles 1C are superimposed on each other on the upper surface of the nail, and the adhesive is Adhesively fixed to each other. Seven days after the treatment day, the inventors confirmed that the toes were substantially completely cured.

(Specific Description of Curing Passage) A photograph of the toes before the treatment day (installation of the wound patch structure) is shown in Figs. 23a and 23b. It was confirmed that nail defects, obvious pain, internal bleeding, inflammation, swelling, and granulation were difficult to walk. A photograph of the toes after the treatment day of treatment (installation of the wound patch structure) is shown in Figures 24a and 24b. After the wound-attached structure was installed, the pain subsided immediately and the walking improved. A photograph of the toes before removal of the wound-attached structure after 7 days of the treatment day is shown in Figures 25a and 25b. A photograph of the toes after removal of the wound-attached structure after substantially 7 days of treatment day is shown in Figures 26a and 26b, substantially completely cured. The inflammation basically subsided and the epidermalization of the granulation part was almost completed. Then it is obvious that it will naturally heal completely after a few days.

[Comparative example 1]

With the same configuration as that of the first embodiment except for the region 2 in which the wound is not provided, the male patient for 45 (the first toe on the left side has inlay), by the first treatment day with the first embodiment The same procedure was used for invasive wound healing. The incarcerated wound state before treatment was basically the same as in Example 1. Appliance exchange and disinfection of the affected area are performed on a regular basis (every week) and repeated treatment is repeated between approximately two months.

(Specific description of the cure) The time to cure is about 50% from the start of treatment to two months later. Walking is still difficult. From the initial installation of the appliance (start of treatment) to about one week later, the pain was relieved, and when the pain did not subside, there was pain left at about two months later.
