Description

[Detailed description of the invention] <Industrial application field> The invention relates to an electric moxibustion device, and more specifically, an electric moxibustion device that transmits the heat of a sheet-shaped energizing heating element to the skin as radiant heat rays through a heat radiation plate. The present invention relates to an electric moxibustion device which prevents conductive heat from being directly transmitted to human skin from a needle guide pipe, a heat radiation plate, and a sheet-like energized heating element.

<Prior art> As is well known, a moxibustion container includes a moxibustion container and a needle guide pipe supported at the center of the moxibustion container, and a heat conductive plate supported by the needle guide pipe and placed facing the skin side of the human body. Electric moxibustion devices having a sheet-shaped energizing heating element disposed on the back surface of the heat conductive plate are widely used. In the past, nichrome wires, thermistors, and the like were used as the energizing heating element, but now sheet-like energizing heating elements are used.

Furthermore, in the past, a metal plate was used as the heat conductive plate, and the heat conductive plate was applied directly to the skin. However, recently, in order to utilize far infrared rays at the same time as having a moxibustion effect, ceramic coating plates have come to be used as the heat conductive plates.

In order to obtain the above-mentioned moxibustion effect, for example, 45 to 50℃
Ideally, the temperature should be changed continuously so that the peak is around 40°C and the trough is around 40°C. Therefore, in order to obtain a good therapeutic effect, it is necessary to control the heat generation state so that the above temperature state is achieved.

In addition, the above-mentioned far-infrared rays effect generally means that far-infrared rays are easily absorbed by the human body, which is said to be good for human physiology, such as improving blood circulation. It is said that these wavelengths are easily absorbed by the human body.

<Problem that the invention attempts to solve> However, if we look at the conventional technology in more detail,
As shown in FIG. 1, the tip 3a' of the needle guide pipe 3' supporting the heat radiating plate 4' made of a ceramic plate and the sheet-shaped energizing heating element 5' is in direct contact with the skin A' side of the human body. is configured to
The conductive heat of the heat radiating plate 4' and the sheet-like energizing heating element 5' was easily transmitted to the skin A.

For this reason, in conventional electric moxibustion devices, it is difficult to heat the heat radiating plate 4 and the sheet-shaped energizing heating element 5 to a high temperature of about 60°C to 90°C, which is necessary to obtain far infrared rays. There was a problem where I couldn't get any results.

In view of the above-mentioned problems, it is an object of the present invention to make it difficult for conductive heat from a heat radiation plate and a sheet-shaped energizing heating element to be transmitted to the skin side, so that a good far-infrared effect can be obtained.

<Means for Solving the Problem> In order to achieve the above object, the present invention has a second technical means. That is, to explain using the reference numerals used in the attached drawings corresponding to the embodiments, the device includes a moxibustion container 1 and a needle guide pipe 3 supported at the center of the moxibustion container 1, and is supported by the needle guide pipe 3, In an electric moxibustion device having a heat radiation plate 4 disposed facing the skin A side of a human body, and a sheet-like energizing heating element 5 disposed on the back surface of the heat radiation plate 4, the heat radiation plate 4 is made of a porous sheet member with high thermal conductivity, and a ceramic coating layer 8 is formed on at least the surface facing the skin A side of the human body among the front and back surfaces of the heat radiation plate, and the moxibustion container 1 The distal end 3a of the needle guide pipe 3 is separated from the skin contact container 7 which engages with the skin A and contacts the skin A of the human body, and the distal end 3a of the needle guide pipe 3 is connected to the heat radiation plate 4 and is energized in sheet form. At this time, the heat radiation plate 4 and the peripheral edges 4a, 5a of the sheet-like energizing heating element 5 and the peripheral wall 1 of the moxibustion container 1 are attached.
b and the peripheral wall 7a of the skin-contact container 7 are supported at a distance from each other, so that the conduction heat of the heat radiating plate 4 and the sheet-like energizing heating element 5 is transferred to the needle guide pipe 3→
This electric moxibustion device is characterized in that the electric power is transmitted from the top 1a of the moxibustion container 1 to the peripheral wall 1b of the moxibustion container 1 to the skin A side of the skin contact container 7.

<Function> In the electric moxibustion device of the present invention, since the heat radiating plate 4 is made of a porous sheet-like member 6 with high thermal conductivity, the heat from the sheet-like energizing heating element 5 disposed on the back side of the plate is efficiently dissipated. It is possible to disperse the heat uniformly in a short time, to transmit the heat to the heat radiating plate 4 at high speed in response to energization, and to apply uniform thermal stimulation to the skin A at a set temperature through the ceramic coating layer 8. can. Moreover, the heat of the sheet-like energizing heating element 5 is
A porous sheet-like member 6 constituting the heat radiation plate 4
Since the ceramic coating layer 8 is heated, the overall heat capacity becomes smaller due to the porosity, and the temperature can be raised more quickly. Thereby, more far infrared rays can be generated from the ceramic coating layer 8. Further, since the ceramic coating layer 8 is thin and the porous sheet-like member 6 is used, the overall heat capacity is small and the surface area is large, so that heat is difficult to accumulate inside and cooling is performed quickly.

As a result, highly responsive and accurate temperature control corresponding to the energization control of the sheet-like energizing heating element 5 is possible, and it is also easy to obtain temperature changes with peaks and troughs, which are essential for obtaining the moxibustion effect. Become.

In addition, the tip 3a of the needle guide pipe 3, the heat radiation plate 4, and the sheet-like energizing heating element 5 are not in direct contact with the human skin A, and the peripheral walls 1b of the moxibustion container 1 and the skin contact container 7, 7a, so the heat radiation plate 4 and the sheet-like current-carrying heating element 5
The ideal temperature for obtaining far infrared radiation is 60℃.
It becomes possible to raise the temperature to as high as ~90°C.
This makes it possible to obtain not only the above-mentioned moxibustion effect but also a good far-infrared rays effect, making it possible to treat a condition closer to that of moxibustion.

<Example> Hereinafter, an example of the electric moxibustion device of the present invention will be described in detail based on the accompanying drawings FIG. 2 and subsequent figures.

FIG. 2 is a sectional view of an electric moxibustion device to which the present invention is applied, FIG. 3 is an enlarged partial cutaway view of a heat radiation plate thereof, and FIG. 4 is a bottom view of the skin contact container.

As shown in FIG. 2, the electric moxibustion device of the present invention includes a moxibustion container 1 and a needle guide pipe 3 supported at the center of the moxibustion container 1 by a mounting nut 2 and a collar 9. A heat radiating plate 4 is disposed at the tip 3a of the needle guide pipe 3, and a sheet-like energizing heating element 5 is attached to the back surface of the heat radiating plate 4. These heat generating parts are covered by a skin contact container 7,
The heat generating part is prevented from coming into direct contact with the skin A.

As shown in FIG. 3, the heat radiation plate 4 is constituted by a porous sheet-like member 6 (in this embodiment, a wire mesh is used). A ceramic coating layer 8 is provided at least on the surface facing the skin A side to facilitate generation of far infrared rays.

The tip 3a of the needle guide pipe 3 is spaced apart from the skin contact container 7. In addition, a heat radiation plate 4 attached to the tip 3a of the needle guide pipe 3, and a peripheral edge 4a of the sheet-like energizing heating element 5,
5a is the peripheral wall 1 of the moxibustion container 1 and the skin contact container 7;
b, 7a are held so as not to come into contact with each other.
As a result, the conductive heat from the heat radiation plate 4 and the sheet-like energizing heating element 5 passes through the needle guide pipe 3 → the top 1a of the moxibustion container 1 → the peripheral wall 1b, and then passes through the skin contact container 1.
This will be transmitted to the A side of the skin.

The sheet-like energizing heating element 5 is connected to an energizing circuit such as an intermittent energizing circuit (not shown) through a lead wire 10, and temperature can be controlled by controlling energization. Further, the bottom surface of the skin contact container 7 has holes 13 as shown in FIG.
By providing a plurality of heat radiation plates 4, the radiation heat including far infrared rays from the heat radiation plate 4 is formed so as to be directly radiated to the skin.

Next, the operation of the electromoxibustion device of this embodiment configured as described above will be explained.

When energized from an energization control circuit such as an intermittent energization circuit (not shown), the sheet-like energizing heating element 5 generates heat.
The heat radiation plate 4 is heated. Since the heat radiating plate 4 is made of a porous sheet-like member 6 with high thermal conductivity, its heat capacity is small due to the porosity. Once this happens, the temperature of the heat radiating plate 5 quickly rises, and far infrared rays are generated from the ceramic coating layer 8 in a short period of time. When the current is turned off, the ceramic coating layer is thin, and since the porous sheet member 6 is used, the overall heat capacity is small and the surface area is large. Therefore, since the heat radiation efficiency is good, heat is difficult to accumulate inside, and cooling is performed quickly. By repeating the above-mentioned operation, the temperature change that is considered ideal for obtaining the moxibustion effect, that is,
It is possible to obtain a temperature change with a peak between 45 and 50 degrees Celsius and a valley around 40 degrees Celsius.

Further, the conductive heat of the heat radiating plate 4 and the sheet-like energizing heating element 5 is transmitted to the skin A side of the skin contact container 7 through the needle guide pipe 3, the top portion 1a of the moxibustion container 1, and the peripheral wall 1b. Therefore, the temperature decreases during this time, so even if the temperature of the heat radiation plate 4 and the sheet-shaped energizing heating element 5 is high, it reaches the appropriate temperature by the time it reaches the skin A of the human body. For this reason, the heat radiating plate 4 and the sheet-like energizing heating element 5 are
It can be heated to the required temperature of 60℃ to 90℃ to obtain far-infrared rays, and better far-infrared rays can be obtained.

In this case, if the temperature sensor 12 is provided in the skin contact container 7, heating can be prevented and problems such as burns can be prevented.

The shape of the bottom surface of the skin-contact container 7 is such that the holes 13 are provided without significantly impairing the strength of the container, and the shape and number thereof are not limited to those in this embodiment.

<Effects> As detailed above, in the present invention, the heat radiating plate is constructed of a porous sheet member with high thermal conductivity, so the heat capacity of the heat radiating plate can be reduced and the surface area can be increased. can. Therefore, the heat radiation plate can be heated/cooled quickly, and the ideal temperature change can be easily and reliably obtained. Moreover, since the heat radiating plate is provided with a ceramic coating layer, far infrared rays can be efficiently generated.
In addition, since the tip of the needle guide pipe, the heat radiation plate, and the periphery of the sheet-like energizing heating element are held so as not to come into contact with human skin or the moxibustion container,
These conductive heat can be prevented from being directly transmitted to the skin. Therefore, the heating element can be heated to a high temperature of about 60°C to 90°C, which is ideal for obtaining far infrared rays. As a result, it is possible to obtain a sufficient far-infrared rays effect in addition to the excellent moxibustion effect due to the above-mentioned temperature change, and it is possible to perform a treatment that is more similar to moxibustion.
