Abstract

PROBLEM TO BE SOLVED: To concentrate the electricity or heat applied on lesion tissues to the deep tissues without dispersion of the electricity or heat on the surface by coating a needle exclusive of a needle head part and needle tip part with a thin insulation layer. SOLUTION: The greater part of the needle exclusive of the needle head part 2 and the needle tip part 1 is coated with the thinnest possible insulation layer 3. Materials having bioaffinity, for example, ceramics, etc., are preferably used for the insulation layer 3. A method for masking the needle head part 2 and the needle tip part 1 and dipping the needle into a solvent contg. a resin, etc., are used in addition to welding means in the case of, for example, the ceramics as the method for coating the needle. The adhesion property of the needle surface may be improved by subjecting the needle surface to a surface roughening treatment, such as sandblasting or chemical etching. As a result, the ordinary use of the needle for acupuncture as an ordinary needle without making combination use of an electrical treatment and moxibustion. Stimuli may be concentrated to the deep lesion tissues.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acupuncture needle used for treatment by a doctor or an acupuncturist, and more particularly, to an acupuncture needle for acupuncture wherein a part other than an acupuncture head and an acupuncture tip is covered with a thin insulating layer.

[0002]

2. Description of the Related Art In acupuncture treatment, acupuncture needles are inserted into the body from the surface of a living body to stimulate an affected area several centimeters deep from the epidermis. In this case, it is effective to apply a stimulus such as electricity or heat through acupuncture. By connecting the acupuncture head to a pulse application power source or burning the grass for moxibustion with the acupuncture head, stimulation such as electricity or heat can be applied to the affected area.

[0003]

However, acupuncture is gold, silver,
Since it is made of a highly conductive metal such as platinum, current or heat is dispersed on the surface of a living body or in a living body, and it has been difficult to concentrate stimulation treatment on deeply affected tissue in the living body.

For example, in the case of pulse current application therapy, as shown in FIG. 3, the presence of sweat, body fat or dust on the epidermis 5,
Due to the intrinsic conductivity of the epidermis 5, the current i was not effectively transmitted to the affected part 4 and leaked to the epidermis in many cases.

Accordingly, the present invention provides an acupuncture needle which can concentrate electricity or heat applied to the head of the acupuncture head on the affected tissue deep in the living body without dispersing on the surface of the living body.

[0006]

Therefore, in the acupuncture of the present invention, an acupuncture needle for acupuncture and moxibustion in which a portion other than the acupuncture head and the tip of the acupuncture is covered with a thin insulating layer. Here, the insulating layer can be made of, for example, an insulating resin such as silicone or ceramic.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an acupuncture needle according to the present invention, wherein 1 is an acupuncture tip, 2 is an acupuncture head, and 3 is an insulating layer which is preferably as thin as possible and which is shown in FIG. Most of the acupuncture is covered as shown in the cross-sectional view. FIG. 3 shows a state in which an acupuncture needle has been inserted into the living body. In this figure, 4 is the affected part, 5 is the epidermis, 6 is the dermis,
7 schematically shows muscles and nerves.

The thin insulating layer 3 is preferably biocompatible, and may be, for example, ceramic, polyethylene, Teflon, nylon, or silicone resin. Polyethylene, nylon, silicone resin, etc. do not impair the original flexibility of acupuncture and are easy to cover.

[0009] The method of coating the insulating layer 3 on the acupuncture needle is, for example, a welding method in the case of ceramic, a method of masking the head part and the tip part of the acupuncture point, and then dipping the needle into a solvent containing a resin. There is also a method of spray-coating a solvent containing a. The thickness and strength of the insulating layer depends on the viscosity of the resin,
It can be easily adjusted by the concentration or the degree of polymerization.

Further, the surface of the acupuncture needle is roughened by sandblasting, chemical etching or the like, so that the adhesion between the insulating layer and the acupuncture needle can be improved.

The acupuncture of the present invention can be used as ordinary acupuncture without being used in combination with electrotherapy and moxibustion.

[0012]

As described above, the acupuncture according to the present invention, as described above, has a portion other than the acupuncture head and the acupuncture tip covered with an insulating layer. The stimulus can be concentrated on the affected area without dispersing the stimulus.

Therefore, according to the acupuncture of the present invention, the effect of acupuncture and moxibustion treatment can be further enhanced.
