Description

  The present invention relates to an acupuncture needle, and more particularly to an acupuncture needle that can easily identify the thickness of a needle with a single acupuncture needle and can be used as a wharf.

  As described in Japanese Patent Application Laid-Open No. 2004-133620, as a conventional needle, a metal needle body having a needle tip portion formed at the tip, and a cylindrical metal needle attached to the base end portion of the needle body There is something that consists of a handle.

  A hook having a metal needle handle can be used as a wharf, but unlike a resin needle handle, the needle handle itself cannot be colored to identify the thickness of the needle body. .

The following products (1) and (2) are available as commercial products with color codes.
(1) An acupuncture needle with a needle tube in which a wedge-shaped color chip of a color corresponding to the thickness of the needle body is inserted between the needle tube and the needle handle.
(2) An acupuncture needle with a needle tube, wherein a resin needle tube is a color needle tube of a color corresponding to the thickness of the needle body.

No. 2006-011190

  However, the product (1) becomes unidentifiable after removing the color chip when using the needle (inserting). In addition, it is necessary to remove the chip every time during the operation, and work efficiency is poor.

  Moreover, although the product of said (2) is identifiable until it inserts using a needle tube, if a needle tube is removed in the middle of or after insertion, it will become unidentifiable after that.

  In actual acupuncture, many needles with different thicknesses are often stabbed at one time, and in this case, the thickness of the stabbed needle cannot be identified.

  The present invention has been made in view of such a situation, so that the needle thickness can be identified by a color code with a single needle so that it can be identified not only at the time of insertion but also after insertion. It is an object of the present invention to provide an acupuncture needle that can be used at a high temperature as a skull.

  In order to solve the above-described problems, acupuncture needles according to the present invention include a metal needle body having a needle tip formed at the tip, and a cylindrical metal needle attached to the proximal end of the needle body. The needle handle has a colored portion made of a resin having flame retardancy or self-extinguishing properties.

As a desirable mode, the colored portion may be a color cap attached to the head of the needle handle, and further, an attachment shaft portion press-fitted into the head of the cylindrical needle handle, and the attachment shaft. And an exposed portion that covers the end surface of the head portion.
Alternatively, the colored portion may be a colored film (colored layer) formed on the outer peripheral surface on the head side of the needle handle.

According to the present invention, since the needle handle has a colored portion, it is possible to identify the thickness of the needle with the color code by the needle needle alone, and therefore not only at the time of insertion but also after insertion. Therefore, when using needles having different thicknesses at the same time, mistakes in taking mistakes can be prevented.
Moreover, since the needle handle is made of metal and the colored portion is made of a resin having flame retardancy or self-extinguishing properties, it can be used as a bun. That is, even if a mogusa (butterfly) is set on the needle handle and ignited, the needle handle and the colored part can withstand the heat of combustion, and therefore can be used safely as a wharf.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a schematic view of an acupuncture needle shown as an embodiment of the present invention.
The scissors needle 1 according to the present embodiment includes a needle body 2, a needle handle 3, and a color cap 4 that is a colored portion.

The needle body 2 is a linear body made of metal such as stainless steel, and has a needle tip portion 2a formed at the tip.
The thickness (wire diameter) of the needle body 2 varies depending on the application, for example, five types of 0.14 mm, 0.16 mm, 0.18 mm, 0.20 mm, and 0.25 mm.

  The needle handle 3 is a cylindrical body made of a metal such as stainless steel, and is attached to the base end portion of the needle body 2 and serves as a handle portion for holding the needle 1. Specifically, by inserting the proximal end portion of the needle body 2 into the distal end portion of the cylindrical needle handle 3 and performing caulking processing from, for example, three points on the outer peripheral side of the needle handle 3, the caulking portion 3 a of the needle handle 3. Thus, the needle body 2 and the needle handle 3 are fixed.

  The color cap 4 can be colored, is made of a resin having flame retardancy or self-extinguishing properties, and is attached to the head (base end) of the cylindrical needle handle 3.

FIG. 2 is an enlarged view of the main part of the eyelid showing the manner of attaching the color cap.
As can be seen from FIG. 2, the color cap 4 is a resin molded product and has a small diameter mounting shaft portion 4a press-fitted into the head of the cylindrical needle handle 3, and the needle handle 3 connected to the mounting shaft portion 4a. And a large-diameter exposed portion 4b projecting over the end face of the head. The exposed portion 4b has the same diameter as the needle handle 3, and the end face on the protruding side is hemispherically rounded. However, the protruding amount and protruding shape of the exposed portion 4b are not limited as long as they can be identified by color and do not affect the handling of the needle.

The color cap 4 is molded from a resin having flame retardancy or self-extinguishing properties.
The term “flame retardant” as used herein refers to a property including a non-flammability (a property of not burning continuously) and a slow combustion rate. Self-extinguishing is a property that burns while exposed to a flame but extinguishes when separated from the flame.
As the resin having flame retardancy or self-extinguishing property, specifically, a thermosetting resin can be used.

As the thermosetting resin, the following resins can be used.
・ Phenolic resin (PF)
・ Epoxy resin (EP)
・ Melamine resin (MF)
・ Urea resin (Urea resin, UF)
・ Unsaturated polyester resin (UP)
・ Alkyd resin ・ Polyurethane (PU)
・ Silicone resin (SI)
Of these, silicone resin (SI) can be used particularly suitably. This is because the material is excellent in colorability and thus can correspond to various colors.

  The color cap 4 is molded and colored with a resin that can be colored. This is because the thickness (wire diameter) of the needle 1 can be identified by the color of the color cap 4 alone.

The correspondence between the wire diameter and the color code is exemplified below.
Wire diameter 0.14mm ... Green wire diameter 0.16mm ... Red wire diameter 0.18mm ... Ivory wire diameter 0.20mm ... Sky blue wire diameter 0.25mm ... Violet

Therefore, when the wire diameters are the above five types, the color caps 4 of the above five types of colors (color codes) are created, and the color (color code) corresponding to the wire diameter is set for each needle 1. Select and install the color cap 4.
However, the above example is shown for reference, and the type of wire diameter and the corresponding color can be arbitrarily set within a range that can be identified by the user (generally an acupuncturist). .

FIG. 3 is a schematic view in the case of an acupuncture needle with a needle tube.
In general, when an acupuncture needle is inserted into the skin, a needle tube is used as a guide for the acupuncture needle to the acupuncture point. In the distribution stage, it is important to protect and secure the needle tip of the needle. For this reason, acupuncture needles are provided with a needle tube to users (generally acupuncturists).

The needle tube 10 is a cylindrical body made of resin, and its length is shorter than the total length of the needle 1 and its inner diameter is larger than the outer diameter of the needle handle 3.
The acupuncture needle 1 and the needle tube 10 are inserted into the needle tube 10 so that the tip of the acupuncture needle 1 is housed in one end portion of the needle tube 10 and the head of the needle handle 3 including the color cap 4. Position so that the portion is exposed from the other end of the needle tube 10.

  In this state, the needle tube 10 and the heel needle 1 (needle handle 3) are temporarily fixed (removably fixed). That is, the inner peripheral surface of the needle tube 10 and the outer peripheral surface of the needle handle 3 are partially contacted to perform high frequency induction heating or microwave heating. Thereby, the resin of the needle tube 10 at the contact portion is melted, and the needle tube 10 and the needle handle 3 can be temporarily fixed at the welded portion 11.

  The acupuncture needle 1 with such a needle tube 10 is not detached from the needle tube 10 due to vibrations during inspection, packaging, transportation, etc. until it is used for acupuncture. In the case of acupuncture, the acupuncture needle 1 can be removed from the needle tube 10 with one hand by holding the needle tube 10 and pushing the end of the needle handle 3.

  However, the positioning and fixing of the needle tube 10 and the eyelet needle 1 are not limited to the above-described welding method, and both the protection and safety of the needle tip portion of the eyelet needle and the ease of handling during use are compatible. It is sufficient if it can be achieved.

According to the acupuncture needle 1 of the present embodiment, the thickness of the needle can be identified by the color of the collar cap 4 at the head of the needle handle 3, so that when using needles with different thicknesses at the same time, , You can prevent mistakes.
Further, as shown in FIG. 3, since the color cap 4 is exposed from the needle tube 10, the thickness of the needle can be identified even in the case of an acupuncture needle with a needle tube.

  Moreover, according to the scissors needle 1 of this embodiment, compared with the conventional product which uses a wedge-shaped chip | tip, the operation | work will become easy by removing the effort which removes a wedge-shaped chip | tip.

  Moreover, according to the hook 1 of this embodiment, it can be safely used as a wharf using the combustion heat of moxa.

FIG. 4 is a diagram showing an example of use as a wharf.
In this example, a pedestal (a wharf cap) 20 is used. The pedestal 20 includes a cylindrical portion 20a that covers and locks the head of the needle handle 3, and a receiving portion 20b that extends from the lower end of the cylindrical portion 20a to the outer peripheral side.

  Therefore, after the needle tip 2a of the acupuncture needle 1 is inserted into the skin S, the pedestal 20 is set on the head of the needle handle 3 of the acupuncture needle 1, and the peg M is held on the pedestal 20. And ignite Mogusa M.

  At this time, the resin-made color cap 4 is exposed to the heat of combustion of Mogusa M. The color cap 4 is a thermosetting resin such as a silicone resin, and is basically a flame-retardant or self-extinguishing resin. In addition, it does not burn or melt. As a result, no unpleasant odor or excessive heat is generated.

When it melts, the molten residue falls, but this is not the case. When the molten residue welds the needle handle 3 and the pedestal 20 and removes the pedestal 20, the acupuncture needle 1 comes off at the same time, causing a situation in which it is difficult to continue the acupuncture treatment, but this is not the case.
Moreover, although it is slight, burning residue may be generated depending on the resin. However, it is a very small amount of dry powdered debris and does not cause welding of the needle handle 3 and the pedestal 20.

  As described above, since the handle of the hook needle (metal needle handle 3 + flame retardant or self-extinguishing color cap 4) withstands the heat of combustion of Mogusa M, it can be safely used as a bun hoe. . Therefore, there is no limitation on the treatment form.

  In addition, although the example which uses the base 20 was shown in FIG. 4, the same effect can be acquired also in the case where a moxa is wound directly on the needle handle 3 and burned.

FIG. 5 is a schematic view of an acupuncture needle with a needle tube shown as another embodiment of the present invention.
In this embodiment, as a colored portion for identifying the thickness of the needle instead of the color cap 4, a colored coating (colored layer) formed on the outer peripheral surface of the needle handle 3 on the head side (site exposed from the needle tube 10). 5 is provided.

The colored coating is formed by applying a resin paint that can be colored and has flame retardancy or self-extinguishing properties.
The resin paint may be either a thermosetting resin or a thermoplastic resin, and may be any resin that can be colored and has flame retardancy or self-extinguishing properties.
In the case of the colored coating 5, since the amount of the resin is small, even if a thermoplastic resin is used and it burns, the amount of burnt residue and melt residue generated is very small and not so bad.

Examples of the resin paint in this case include the following resins. In addition, some of the following resins have both a thermosetting resin and a thermoplastic resin with the same name.
-Epoxy resin-Acrylic resin-Urethane resin-Polyamide resin-Fluorine resin Of these, the epoxy resin can be used particularly suitably.

  It should be noted that the illustrated embodiments (and the dimensions, colors, etc. shown in this specification) are merely examples of the present invention, and the present invention is claimed in addition to those shown directly by the described embodiments. It goes without saying that various improvements and modifications made by those skilled in the art are included within the scope of the above.
