Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a brush for treating athlete's foot.

[Conventional technology]

Athlete's foot is caused by the proliferation of tinea fungi, and it occurs not only on the feet (tinea pedis) but also, less frequently, on the hands (tinea mantis) and nails (tinea unguium).

The most common type of tinea pedis is the interdigital erosion type, which occurs most often between the fourth and fifth toes and spreads between the other toes and toward the sole of the foot. There are 3 types: the vesicular/scaling type, which occurs most frequently on the side edges and arches, and causes small blisters to peel off when dry; and the rarest type, the hyperkeratotic type, in which dead skin cells proliferate mainly on the heels. There are two types of disease.

Trichophyton is thought to grow parasitically on the stratum corneum, which is the outermost layer of the skin rich in keratin, and on the nails, and when scales containing bacteria are peeled off from the affected area, it infects other areas.

Therefore, in order to treat athlete's foot, it is said that the affected area must be thoroughly washed and cleaned, and a drug must be applied several times a day.

However, since the affected area is made up of stratum corneum, it is not only difficult to completely remove the scales, but also because it is very troublesome to repeat the above treatment every day, people tend to neglect treatment, which is the reason why athlete's foot does not heal easily. was.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a brush for treating athlete's foot that can completely clean the affected area and simultaneously apply a chemical.

[Means for solving problems]

This invention has a porous material made of polysaccharides, proteins, or derivatives thereof as at least a part of the bristles composition of the brush, an appropriate drug is immobilized on the porous material, and the bristles are used at least as part of the hair transplantation. The tip of the hair transplanted part is pointed.

[Effect]

In this invention, at least a part of the bristles of the brush contain a porous substance, and a drug is appropriately fixed to this porous substance, so that the brush itself can be endowed with medicinal effects. Therefore, by brushing the affected area, it is possible to remove scales, grime, and dirt from the affected area, and at the same time apply a drug to the affected area.

Since the drug is fixed in a porous material, it can be released gradually over a long period of time.

The porous substance is composed of polysaccharides, proteins, or derivatives thereof, and these polysaccharides are naturally derived polymers and therefore have high safety.

In addition, since the tip of the flocked part is pointed,
Even difficult-to-treat affected areas such as between the fingers can be easily brushed.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings.

The brush according to the present invention has at least a part of the bristles composed of a porous substance made of polysaccharides, proteins, or derivatives thereof, a suitable drug is immobilized on the porous substance, and the bristles are at least used for hair transplantation. The tip of the hair transplanted part is pointed.

The polysaccharide used in this invention is preferably one or two of chitin, chitosan, cellulose, dextran, agarose, starch, and the like.
In particular, porous materials derived from chitosan and ginger starch are effective. These derivatives include:
Examples include ion-exchangeable derivatives of these, derivatives with hydrophobic groups, and derivatives to which tannins are bonded.

Proteins in this invention include gluten, silk thread, and the like.

To produce a porous substance from a polysaccharide or its derivative, for example, chitosan is produced by dissolving low molecular weight chitosan in an acidic solution, and dropping this solution into a basic solution to coagulate it into granules. The granular porous chitosan thus obtained has uniform particle size, uniform micropores, and a large specific surface area, so it has a high ability to immobilize various drugs.

In order to produce hair having such a porous material as at least a part of the hair composition, it is necessary to use a porous material (for example, in the above-mentioned granular porous chitosan, the particle size is 1 to 15 μm,
A material having a specific surface area of 2 to 5 m ² /g) alone or a mixture with a synthetic resin such as nylon is extruded into a thread form from a molding machine, and the wire diameter is about 25 μm.

Next, the brush thus produced is impregnated with a drug, and the drug is fixed in the porous material. Examples of drugs include pyrrolenitrine, crotamiton, salicylic acid, benzalkonium chloride, and imidazole drugs. Immobilization means include physical adsorption and covalent bonding by functional groups (amino group, carboxyl group, hydroxyl group, imidazole group, phenol group, sulfhydryl group, etc.).

The bristles imparted with medicinal properties in this manner are implanted into the main body 1 of the brush. As shown in FIGS. 1 to 3, the brush has the tip of the main body 1 and the tip of the bristle part 2 shaped like a point, and FIGS. 1 and 2 show one side 1.
Only the side 1a and 1b in FIG. 3 are tilted. For hair transplantation, in addition to using only the above-mentioned hair, synthetic hair such as nylon or natural hair such as pig hair or white horse hair may be added to create a mixed hair.

By brushing the affected area, the brush configured as described above removes scales, dirt, and dirt from the affected area, and at the same time rubs the affected area. Since the drug is separated and released from the porous material during brushing, stable drug efficacy is maintained for a long time. Furthermore, since the porous material uses naturally derived polymers such as polysaccharides, it does not induce cancer, inflammation, or allergies. Furthermore, even if the affected area is difficult to treat, such as between the fingers, the tip of the hair transplanted part is pointed, so it can be easily brushed.

〔Effect of the invention〕

This invention has a porous substance in at least a part of the bristles of the brush, and the drug is fixed to the porous substance, so that just by brushing, you can completely clean the affected area and apply the drug at the same time. It can be carried out. Therefore, although the treatment is simple, it is highly effective.

Furthermore, since the toothbrush uses a porous substance made of polysaccharide, protein, or a derivative thereof, the toothbrush has long-lasting medicinal effects and is highly safe.

In addition, since the tip of the flocked part is pointed,
Even difficult-to-treat affected areas can be easily treated.
