Description

The present invention relates to an acupuncture needle (acupuncture needle), and more particularly to an acupuncture needle that can easily identify the thickness of the needle by itself and can be used as acupuncture head acupuncture needle.

As a conventional acupuncture and moxibustion needle, as described in Patent Document 1, a metal needle body having a needle tip formed at the tip and a cylindrical metal needle attached to the base end of the needle body. Some are composed of a handle.

Acupuncture needles with a metal needle handle can be used as moxibustion acupuncture needles, but unlike resin needle handles, the needle handle itself cannot be colored to identify the thickness of the needle body. ..

Commercially available products with color codes include the following products (1) and (2).
(1) An acupuncture and moxibustion needle with a needle tube, in which a wedge-shaped color tip of a color corresponding to the thickness of the needle body is inserted between the needle tube and the needle handle.
(2) Acupuncture and moxibustion needles with needle tubes, in which a resin needle tube is used as a colored needle tube with a color corresponding to the thickness of the needle body.

Re-table 2006-0111190

However, the product of (1) above cannot be identified thereafter if the color tip is removed when using (inserting) the acupuncture and moxibustion needle. In addition, it is necessary to remove the tip every time the treatment is performed, resulting in poor work efficiency.

Further, the product of (2) above can be identified until the needle tube is used for insertion, but if the needle tube is removed during or after the insertion, the product cannot be identified thereafter.

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

The present invention has been made in view of such an actual situation, and the thickness of the needle can be identified by a color code with the acupuncture and moxibustion needle alone so that the acupuncture and moxibustion needle can be identified not only at the time of insertion but also after the insertion. An object of the present invention is to provide acupuncture and moxibustion needles that can be used as head acupuncture at high temperatures.

In order to solve the above problems, the acupuncture and moxibustion needle according to the present invention has a metal needle body having a needle tip formed at the tip and a cylindrical metal needle attached to the base end of the needle body. Consists of including the handle
, A acupuncture needle used as Kyuatama acupuncture by burning sets the of moxa to the needle handle, the needle handle is to have a colored portion comprising a silicone resin having a flame-retardant or self-extinguishing property, the The burning temperature of moxa is characterized by being equal to or higher than the temperature at which the colored portion burns.

As a desirable form, the colored portion may be a color cap to be attached to the head of the needle handle, and further, a mounting shaft portion to be press-fitted into the head of the cylindrical needle handle, and the mounting shaft. It is preferable to include an exposed portion which is connected to the portion and covers the end face of the head.
Alternatively, the colored portion may be a colored film (colored layer) formed on the outer peripheral surface of the needle handle on the head side.

According to the present invention, since the needle handle has a colored portion, the thickness of the acupuncture and moxibustion needle alone can be identified by a color code not only at the time of insertion but also after insertion. Therefore, when needles of different thicknesses are used at the same time, it is possible to prevent mistakes in taking the needles.
Further, since the needle handle is made of metal and the colored portion is made of a flame-retardant or self-extinguishing resin, it can be used as a moxibustion acupuncture needle. That is, even if the moxa (moxa) is set on the needle handle and ignited, the needle handle and the colored part withstand the heat of combustion, so that it can be safely used as a moxibustion acupuncture needle.

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 acupuncture needle 1 of the present embodiment is composed of a needle body 2, a needle handle 3, and a color cap 4 which is a colored portion.

The needle body 2 is a linear body made of metal such as stainless steel, and a needle tip portion 2a is formed at the tip thereof.
The thickness (wire diameter) of the needle body 2 varies depending on the intended use, and is, 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 metal such as stainless steel, and is attached to the base end portion of the needle body 2 to serve as a handle portion for holding the acupuncture and moxibustion needle 1. Specifically, the base end portion of the needle body 2 is inserted into the tip end portion of the cylindrical needle handle 3, and the caulking portion 3a of the needle handle 3 is caulked from, for example, three points on the outer peripheral side of the needle handle 3. Then, the needle body 2 and the needle handle 3 are fixed.

The color cap 4 is made of a colorable, flame-retardant or self-extinguishing resin, and is attached to the head (base end portion) of the cylindrical needle handle 3.

FIG. 2 is an enlarged view of a main part of the acupuncture and moxibustion needle showing the attachment mode of 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 a needle handle 3 connected to the mounting shaft portion 4a. It is configured to include a large-diameter exposed portion 4b that covers and projects the end face of the head of the head. The exposed portion 4b has the same diameter as the needle handle 3, and the end face on the protruding side thereof has a hemispherical roundness. However, the protruding amount and protruding shape of the exposed portion 4b are not limited as long as they can be color-identified and do not affect the handling of the acupuncture and moxibustion needles.

The color cap 4 is molded from a flame-retardant or self-extinguishing resin.
The flame retardant here means a property that includes nonflammability (property that does not burn continuously) and has a slow burning rate. In addition, self-extinguishing property refers to the property of burning while exposed to a flame, but extinguishing the fire when separated from the flame.
Specifically, a thermosetting resin can be used as the resin having flame retardancy or self-extinguishing property.

The following resins can be used as the thermosetting resin.
・ Phenol formaldehyde (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 extremely preferably. This is because the material has excellent colorability and can be used in various colors.

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

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

Therefore, when the wire diameters are the above five types, a color cap 4 having the above five types of colors (color code) is created, and each acupuncture needle 1 has a color (color code) corresponding to the wire diameter. Select and attach the color cap 4.
However, the above example is shown for reference, and the type of wire diameter and the color corresponding to each 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.
Generally, when inserting an acupuncture needle into the skin, a needle tube is used as a guide for the acupuncture needle to the acupuncture point. At the distribution stage, it is important to protect the tip of the acupuncture and moxibustion needle and ensure its safety. For this reason, acupuncture needles are provided to users (generally acupuncturists) with needle tubes.

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

Then, in this state, the needle tube 10 and the acupuncture and moxibustion 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 brought into contact with each other to perform high-frequency induction heating or microwave heating. As a result, 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.

In such an acupuncture needle 1 with a needle tube 10, the acupuncture needle 1 does not come off from the needle tube 10 due to vibration during inspection, packaging, transportation, etc. until it is used for acupuncture treatment. Further, during acupuncture treatment, the acupuncture needle 1 can be removed from the needle tube 10 with one hand by pinching the needle tube 10 and pressing the end of the needle handle 3.

However, the positioning and fixing of the needle tube 10 and the acupuncture needle 1 is not limited to the above welding method, and both protection and safety of the needle tip of the acupuncture needle and ease of handling during use are compatible. It is only necessary to be able to plan.

According to the acupuncture and moxibustion needle 1 of the present embodiment, the thickness of the acupuncture and moxibustion needle can be identified by the color of the color cap 4 of the head of the needle handle 3, so that when needles having different thicknesses are used at once. , You can prevent mistakes in taking 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.

Further, according to the acupuncture needle 1 of the present embodiment, the operation is facilitated by eliminating the trouble of removing the wedge-shaped tip as compared with the conventional product using the wedge-shaped tip.

Further, according to the acupuncture needle 1 of the present embodiment, it can be safely used as a moxibustion acupuncture needle utilizing the heat of combustion of moxa.

FIG. 4 is a diagram showing an example of use as moxibustion acupuncture.
In this example, the pedestal (moxibustion acupuncture cap) 20 is used. The pedestal 20 is composed of a tubular portion 20a that covers and locks the head of the needle handle 3, and a receiving portion 20b that extends outward from the lower end portion of the tubular portion 20a.

Therefore, after inserting the needle tip portion 2a of the acupuncture needle 1 into the skin S, the pedestal 20 is set on the head of the needle handle 3 of the acupuncture needle 1 and the moxa M is held by the pedestal 20. Then, ignite the moxa M.

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

When it melts, the melted residue may fall off, but this is not the case. When the needle handle 3 and the pedestal 20 are welded together and the pedestal 20 is removed, the melted residue causes the acupuncture needle 1 to come off at the same time, which makes it difficult to continue the acupuncture treatment, but this is not the case.
In addition, depending on the resin, burning residue may be generated, albeit slightly. However, it is a very small amount of dry powdery burning residue, and does not cause welding of the needle handle 3 and the pedestal 20.

As described above, the handle of the acupuncture needle (metal needle handle 3 + flame-retardant or self-extinguishing color cap 4) withstands the heat of combustion of moxa M, so it can be safely used as moxibustion acupuncture. .. Therefore, the treatment form is not limited.

Although an example in which the pedestal 20 is used is shown in FIG. 4, the same effect can be obtained even when the moxa is directly wound around 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 the present embodiment, as a colored portion for identifying the thickness of the needle instead of the color cap 4, a colored film (colored layer) coated on the outer peripheral surface of the head side (the portion exposed from the needle tube 10) of the needle handle 3 is formed. 5 is provided.

The colored film is coated with a resin paint that can be colored and has flame retardancy or self-extinguishing property.
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 property.
In the case of the colored film 5, since the amount of the resin is small, a thermoplastic resin is used, and even if it burns, the amount of burnt residue and melted residue generated is very small, and it is 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 even if they have the same name.
-Epoxy resin-Acrylic resin-Urethane resin-Polyamide resin-Fluororesin Of these, epoxy resin can be used extremely preferably.

It should be noted that the illustrated embodiments (and the dimensions, colors, etc. shown in the present specification) merely illustrate the present invention, and the present invention is claimed in addition to those directly shown by the described embodiments. Needless to say, it includes various improvements and changes made by those skilled in the art within the scope of.
