Definitions
- the present invention relates to a bandage structure for treating a wound caused by an ingrown nail. More particularly, the present invention is a bandage structure that is applied to a finger along the side nail plate edge to treat a wound caused by an ingrown nail, and (i) to adhere to the wound caused by an ingrown nail.
- a wound adhesion region having a flexible surface for wound adhesion
- a guide region having a slide groove that receives the side nail plate edge and is slidable in the longitudinal direction of the nail along the side nail plate edge.
- the bandage structure has a substantially rod shape, and the slide groove extends in the longitudinal direction of the bandage structure over at least a part of the distance between the front end portion and the rear end portion of the bandage structure.
- the present invention relates to a bandage structure characterized in that when the bandage structure is attached to a finger, the wound-adhesive flexible surface is guided to the position of the wound by the ingrown nail.
- the bandage structure of the present invention is used, the cooperation between the wound contact area and the guide area results in the vicinity of the tip of the nail regardless of the degree of deformation of the ingrown nail and the severity of wound pain due to the ingrown nail.
- the adhesive bandage structure of the present invention also exhibits an effect of correcting the ingrown nail by the effect of pushing up the side nail plate edge (side edge portion of the nail), and thus has a function of assisting the correction of the ingrown nail.
- curly nail and “ingrown nail”, and these terms are often used interchangeably.
- a symptom that becomes a “curly nail” is often referred to as a “curved nail”, and a symptom in which both ends of a strongly curved nail bite into the skin or flesh (soft tissue) is often referred to as “an ingrown nail”.
- invaginated nail is used as a general term for nail deformities that cause wounds and pain in a patient's finger. In the case of an ingrown nail, one or both side edges of the nail bite deeply into the nail groove as the nail grows, and pierce the soft tissue (nail groove or nail bed meat), causing inflammation, pain or severe pain Draw.
- Patent Document 4 Japanese Patent Application Laid-Open No. 2002-360619 (Patent Document 5), WO 2008-142880 (Patent Document 6), and Japanese Patent No. 5579913 (Patent Document 7). Can be referred to.
- the surgical method is complicated, and the nail plate width is permanently narrowed by the operation. Further, in the method by surgical operation, the nail that has bitten into the soft tissue is partially cut and removed, so that it is difficult to perform the operation when there is a risk of bacterial infection. In addition, even if the nail is partially removed by surgical operation and the ingrown nail is temporarily corrected, the ingrown nail is not recurrence corrected after the operation. There are many cases to do. Therefore, the idea that a method that does not rely on a surgical operation, that is, a conservative method is desirable as a method for correcting an ingrown nail is becoming common.
- Patent Documents 1 to 7 Among the methods using correction tools and correction devices described in Patent Documents 1 to 7, some ingrown nails (deformed nails) themselves can be corrected fairly well. However, none of the methods in Patent Documents 1 to 7 exhibits a direct therapeutic effect on wounds caused by ingrown nails. Therefore, in general, any of the methods of Patent Documents 1 to 7 treats wounds caused by ingrown nails effectively and efficiently, and alleviates the pain rapidly and significantly (ie, immediate treatment). Is not possible).
- Examples of conventional methods for treating wounds caused by ingrown nails include a method including applying bandages to the wound, and a metal body or resin body in which the side edges (side nail caudal edges) of the ingrown nails are elongated.
- a method including covering with is known.
- As a method including applying a bandage to a wound with an ingrown nail for example, JP 2012-125527 A (Patent Document 8) and JP 2013-81723 A (Patent Document 9) can be referred to.
- As a method including covering the side edge portion of the ingrown nail with an elongated metal body or resin body Japanese Patent Application Laid-Open No. 2004-329646 (Patent Document 10) and US Patent Application Publication No. US2007 / 0287945A1 (Patent Document) 11) can be referred to.
- Patent Document 8 and Patent Document 9 have substantially the same structure as a normal emergency bandage except that the position of the wound pad (part for wound covering) is slightly different from a general emergency bandage. It is what you have.
- using the methods described in Patent Document 8 and Patent Document 9 it is possible to treat a wound near the tip of the ingrown nail. Treatment of wounds near the base of the nail is virtually impossible. As described above, when the ingrown nail becomes severe, the inflammation spreads to the base of the nail and the pain becomes severe, so that the treatment of the wound near the base of the ingrown nail is substantially impeded. Being possible means that it is virtually impossible to treat a wound with a severely ingrown nail. Therefore, according to the methods described in Patent Document 8 and Patent Document 9, a wound caused by an ingrown nail is effectively and efficiently treated, and the pain is rapidly and greatly alleviated (that is, immediate treatment is performed). To do) is impossible.
- Patent Document 10 Japanese Patent Application Laid-Open No. 2004-329646 discloses an “ingrown nail treatment tool” including a tube made of a hard material having a C-shaped cross-sectional shape. This ingrown nail treatment tool is attached to a finger by inserting a side edge portion (side nail back edge) of the ingrown nail into a gap portion having a C-shaped cross section. When this ingrown nail treatment tool is attached to a finger, the side edge of the ingrown nail is covered with the tube, so that if the wound due to the ingrown nail is mild, the pain of the wound will be reduced over time. There is some reduction.
- the ingrown nail treatment tool of Patent Document 10 does not have a structural feature for actively treating wounds caused by ingrown nails, it has a direct therapeutic effect on wounds caused by ingrown nails. It does not perform and wounds with severely ingrown nails are virtually impossible to treat. Therefore, even with the ingrown nail treatment tool of Patent Document 10, a wound caused by an ingrown nail can be effectively and efficiently treated, and the pain can be rapidly and greatly relieved (that is, an immediate effective treatment can be performed). To do) is impossible.
- the gist of the method described in Patent Document 11 is that the side nail contour that is in close contact with the side edge of the ingrown nail is pushed sideways with a finger to expose the side edge of the ingrown nail and the wound site, and then the invagination
- the side edge of the nail is covered with an elongated soft resin piece having a U-shaped cross section (member called “protecting gutter”), and thus the side edge of the ingrown nail and the wound site are isolated from each other, It is to promote the healing of.
- the known method using a correction tool or a correction device does not exert a direct therapeutic effect on a wound caused by an ingrown nail. It is impossible to treat the pain efficiently and efficiently and relieve the pain rapidly and significantly.
- a known method including applying bandages to the wound to treat a wound caused by an ingrown nail, or covering a side edge of the ingrown nail with an elongated metal body or resin body Even in the known method including the treatment of the wound near the base of the nail (the wound caused by the severed ingrown nail), the wound by the ingrown nail is effectively and efficiently treated. It is impossible to treat and relieve the pain quickly and significantly.
- the present inventor conducted intensive research to solve the above-mentioned problems, and as a result, the bandage structure attached to the finger along the side nail plate edge to treat the wound caused by the ingrown nail And (i) a wound adhesion area having a wound-adhesive flexible surface for adhering to a wound with an ingrown nail, and (ii) receiving the side nail plate edge and A guide region having a slide groove slidable in a longitudinal direction, the bandage structure has a substantially rod-like shape, and the slide groove is a distance between a front end portion and a rear end portion of the bandage structure Extending over the length of the bandage structure over at least a portion of the bandage, and when the bandage structure is attached to a finger, the wound-adhesive flexible surface is guided to the position of the wound by the ingrown nail.
- the characteristic adhesive bandage structure can be solved by the characteristic adhesive bandage structure. It was heading.
- the wound contact area (i) having a flexible surface for close contact with the wound due to the ingrown nail and the side nail plate edge can be received and slid along the side nail plate edge in the longitudinal direction of the nail.
- the unique structure combined with the guide area (ii) having a sliding groove makes it possible to determine the position of the wound of the ingrown nail in the longitudinal direction of the nail regardless of the severity of the ingrown nail. Nevertheless, it has been found that a flexible surface for wound contact can be reliably guided to the position of the wound. Based on such knowledge, the present invention has been completed.
- a flexible surface for close contact with the wound can be obtained regardless of the severity of the ingrown nail and regardless of where the wound due to the ingrown nail is located in the longitudinal direction of the nail. Since it can be surely guided to the position of the wound, not only the ingrown nail wound near the tip of the nail, but also the ingrown nail wound near the base of the nail, which is difficult to treat effectively and efficiently with the prior art. Therefore, the wound caused by the ingrown nail can be treated effectively and efficiently, and the pain of the wound caused by the ingrown nail can be relieved rapidly and greatly.
- the adhesive bandage structure of the present invention When using the adhesive bandage structure of the present invention, even if the wound to be treated is located at the root of the nail (covered by the nail fold and cannot be seen), the flexible surface for wound adhesion is extended to the wound. Can be guided reliably. This is impossible with the prior art.
- the adhesive bandage structure of the present invention also exhibits an effect of correcting the ingrown nail by the effect of pushing up the side nail plate edge (side edge portion of the nail), and thus has a function of assisting the correction of the ingrown nail.
