Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a toothbrush having various medicinal effects.

[Conventional technology]

Conventional toothbrushes do not have any medicinal properties in and of themselves, and have always been used to brush teeth. Therefore, if it is possible to impart various medicinal effects to the toothbrush itself,
Brushing your teeth becomes unnecessary and becomes extremely convenient. However, it has been difficult to impart medicinal efficacy to toothbrush brushes and to maintain the medicinal efficacy stably for a long period of time. Furthermore, it was difficult to achieve this from the viewpoint of safety, such as the fact that it is not carcinogenic and does not cause inflammation or allergies.

[Problem that the invention seeks to solve]

Therefore, it is an object of the present invention to provide a toothbrush that has medicinal effects in itself, lasts for a long time, and is safe.

[Means for solving problems]

The present invention provides a toothbrush that has at least a part of the brush composition made of a porous substance made of polysaccharide, protein, or a derivative thereof, and has an appropriate drug immobilized on the porous substance. This is included in part.

[Effect]

In this invention, at least a part of the brush composition of the toothbrush has a porous substance, and a drug is appropriately fixed to this porous substance. Therefore, it is possible to impart medicinal effects to the toothbrush, and the drug can be gradually applied over a long period of time. can be released.

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

〔Example〕

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

The toothbrush according to the present invention has a porous substance made of polysaccharides, proteins, or derivatives thereof in at least a part of the brush composition, and an appropriate drug is immobilized on the porous substance, and this brush has at least one part of the bristles. It is included in the section.

The polysaccharides in this invention include chitin, chitosan,
One or two of cellulose, dextran, agarose, starch, etc. are preferred. In particular, porous materials derived from chitosan and potato starch are effective. Examples of these derivatives include ion-exchangeable derivatives, derivatives with hydrophobic groups, and tannin-bonded derivatives. Examples of proteins in the present 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 a uniform particle size, uniform micropores, and a large specific surface area, so it has a high ability to immobilize various drugs.

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

Next, the brush thus produced is impregnated with a drug, and the drug is fixed in the porous material. For example, as a drug,
These include water-soluble azulene to prevent alveolar pyorrhea, chlorhexidine gluconate to prevent dental plaque and bad breath, vitamin E to strengthen the gums, and an astringent. 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 toothbrush (1) shown in the drawing is one in which the brushes (2) endowed with medicinal properties are implanted in the head (3) of the toothbrush (1). For hair transplantation, in addition to applying medicinal properties and using only a brush, synthetic hair such as nylon or natural hair such as pig hair or white horse hair may be added to create a mixed hair.

In the toothbrush constructed as described above, since the drug is separated and released from the porous material during use, the drug maintains stable drug efficacy for a long period of time. Furthermore, since the porous material uses naturally derived polymers such as polysaccharides, it does not induce cancer or cause oral inflammation or allergies.

〔Effect of the invention〕

This invention has a porous substance in at least a part of the brush composition and fixes the drug to the porous substance, so it is possible to impart medicinal efficacy to the toothbrush itself and maintain the medicinal efficacy for a long time. can.

Furthermore, since the porous substance is composed of polysaccharides, proteins, or derivatives thereof, it has high safety.

[Brief explanation of the drawing]

The drawing is a perspective view showing an embodiment of the toothbrush according to the present invention.
