Hereinafter, embodiments of the present invention will be described. Also, the same reference numerals are given to the same elements throughout the present embodiment.

(First embodiment of the present invention)
The electric thermotherapy device pad according to this embodiment will be described with reference to FIGS. The electric thermotherapy device using the electric thermotherapy device pad according to the present embodiment activates proteins and normalizes biological functions by simultaneously applying electrical stimulation and thermal stimulation to the same part in the living body. (See Patent Documents 1 and 2). When electric thermotherapy is performed, a pair of electric thermotherapy device pads are attached to different parts of the living body, a weak pulse current is passed between the pair of electric thermotherapy device pads, and the electric thermotherapy device pad is Heat the applied part to give a thermal stimulus. The pad for an electrical and thermal treatment device according to the present embodiment appropriately applies the electrical stimulation and thermal stimulation as described above to the affected part of the living body, and improves the wearing feeling to moisturize the skin.

FIG. 1 is a diagram showing an example of use of a pad for an electric thermotherapy device according to the present embodiment. The electric thermotherapy device 100 using the electric thermotherapy device pads 1 and 2 according to the present embodiment attaches a pair of electric thermotherapy device pads 1 and 2 to different parts of the living body 10, and this pair of electric thermotherapy devices. The current is generated by controlling the input voltage supplied from the power supply 3 between the therapeutic device pads 1 and 2, and the electric thermal treatment device pads 1 and 2 generate heat to give electrical stimulation and thermal stimulation.

As will be described in detail below, each of the pads 1 and 2 for an electric thermotherapy device can simultaneously apply electrical stimulation and thermal stimulation to the site to which the living body 10 is attached, and therefore, via heat shock proteins and ubiquitinated proteins. The living body can be normalized. In addition, by maintaining the electric thermotherapy device pads 1 and 2 in a moist state, it is possible to energize a pulse current deep into the skin while moisturizing the skin.

FIG. 2 is a cross-sectional view showing a first structure of the electric thermotherapy device pad according to the present embodiment. In FIG. 2 (A), the pads 1 and 2 for an electrothermal therapy device are directly attached to the living body 10, and are provided with an adhesive layer 11 made of a nonwoven fabric having a water retention function, and the back side of the adhesive layer 11 (adhesive layer 11). On the back side of the weak current sheet 12, and a weak current sheet 12 that is laminated on the opposite side of the surface that becomes the living body 10 side) and that conducts a weak pulse current from the oscillation electrode 13; A laminated insulating layer 14 and a thermal sheet 15 laminated on the back side of the insulating layer 14 are provided.

Since the adhesive layer 11 is made of a non-woven fabric, it is gentle to the skin and feels good, so that the user can improve the feeling of wearing the pads 1 and 2 for the electric thermotherapy device. Moreover, since it has a water retention function, it can moisturize the skin and protect the skin from drying. The weak current sheet 12 gives a pulse current supplied from the power source 3 to the oscillation electrode 13 to the living body 10 as an electrical stimulus through the adhesive layer 11. At this time, since the pulse current is passed through the moisture retained in the adhesive layer 11, the current-carrying efficiency can be increased and the depth of the skin and the gap can be sufficiently achieved through the moisture that has penetrated into the skin. Electric stimulation can be given. The thermal sheet 15 has a function of generating heat, and gives a thermal stimulus of 38 ° C. to 45 ° C. to the skin through the insulating layer 14, the weak current sheet 12 and the adhesive layer 11. Further, by vaporizing the water retained in the adhesive layer 11 by the heat generated by the thermal sheet, it is also possible to expect a moistening effect by steam on the skin.

FIG. 2 (B) shows a structure when the adhesive layer 11 in FIG. 2 (A) is composed of a nonwoven fabric layer 11a and a water retention sheet 11b. In the case of the structure of FIG. 2 (A), the non-woven fabric previously wetted is used as the adhesive layer 11, and when the moisture is lost, the nonwoven fabric is moistened again. In the case of the structure of FIG. Since the nonwoven fabric layer 11a is constantly moistened by moisture from 11b, it is not necessary to frequently wet the nonwoven fabric. The water retention sheet 11b is, for example, a gel-like sheet, and the nonwoven fabric layer 11a that directly touches the skin is always wet by allowing moisture to permeate the nonwoven fabric layer 11a little by little. That is, after the moisture of the water retaining sheet has permeated the nonwoven fabric layer 11a, the pad surface on the side in contact with the skin is in the same state as in FIG.

As shown in FIG. 2, the thermal sheet 15 is disposed so as to cover the entire back side of the insulating layer 14 and the entire side surfaces of the adhesive layer 11, the weak current sheet 12, and the insulating layer 14. It is desirable. By carrying out like this, it becomes possible to maintain the moisture of the surface of the skin for a long time, without taking away the moisture and vapor retained by the adhesive layer 11 to the outside. Moreover, since the heat from the thermal sheet 15 can be efficiently transmitted to the adhesive layer 11, the moisture retained in the adhesive layer 11 can be vaporized to make it more gentle to the skin.

3 and 4 are sectional views showing a second structure of the electric thermotherapy device pad according to the present embodiment. 3 and 4 is a water repellent layer having water repellency between the insulating layer 14 and the thermal sheet 15 in the pads 1 and 2 shown in FIG. 16 is formed. 3A, a water repellent layer 16 is formed on the back side of the insulating layer 14 in the structure of FIG. 2A, and FIG. 3B shows an insulating layer 14 in the structure of FIG. A water repellent layer 16 is formed on the back side of the substrate. In this way, by forming a layer having water repellency on the back side of the adhesive layer 11 that is at least water-retained, moisture of the adhesive layer 11 can be maintained for a long time without letting the moisture of the adhesive layer 11 escape to the back side. It becomes possible to do.

4A covers the entire back side of the insulating layer 14 and the entire side surfaces of the adhesive layer 11, the weak current sheet 12, and the insulating layer 14 in the structure of FIG. 3A. A water repellent layer 16 is formed. FIG. 4B shows the entire structure on the back side of the insulating layer 14 as well as the adhesive layer 11, the weak current sheet 12 and the insulating layer 14 in the structure of FIG. 3B. The water repellent layer 16 is formed so as to cover the entire side surface. By doing so, it becomes possible to reliably keep the moisture on the surface of the skin long by confining the moisture and vapor retained in the adhesive layer 11 inside without reliably taking them out.

3 and 4, the water repellent layer 16, the insulating layer 14, and / or the weak current sheet 12 may have an integral structure, and the integral structure itself may have water repellency. That is, the weak current sheet 12 and the insulating layer 14 may be formed of, for example, a rubber agent having water repellency and function as the water repellent layer 16. In that case, the weak current sheet 12 and / or the insulating layer 14 may be disposed so as to cover the entire back surface side and the entire side surface of the adhesive layer 11.

FIG. 5 and FIG. 6 are diagrams showing a structure in the case where the heat generated by the thermal sheet 15 is generated by electrical means in the above-described pads 1 and 2 for the electric thermal therapy device. FIG. 5A shows a structure of FIG. 2A in which a heating part 22 is provided instead of the heating sheet 15, and FIG. 5B shows a structure of the heating sheet 15 in the structure of FIG. Instead, the heating unit 22 is provided. FIG. 6 is a plan view of the weak current sheet 12, the insulating layer 14, and the heating portion 22.

In FIG. 5, a heat generating sheet 28 made of oriented carbon fibers is disposed on the back side of the insulating layer 14, and elongated

heat generating electrodes

26 and 27 are disposed on the heat generating sheet 28. . The

heat generating electrodes

26 and 27 are disposed so that the orientation direction and the longitudinal direction of the heat generating sheet 28 coincide with each other, and are spaced apart from each other along both end portions 30 and 31 of the heat generating sheet 28. The exposed portions on the side and back sides of the

heat generating electrodes

26 and 27 are covered with an electrode cover 29 having the same material as the heat generating sheet 28 and having the orientation in the same direction (the same direction as the longitudinal direction of the heat generating electrodes 26 and 27). The Since the resistance between the

heating electrodes

26 and 27 is formed of carbon fibers having orientation in a direction parallel to the longitudinal direction of the electrodes, the

heating electrodes

26 and 27 are not short-circuited by the carbon fibers. Heat can be generated by an appropriate resistance value between the parallel carbon fibers.

The outer sheet 32 is disposed on the back side. A thermocouple 33 is provided to measure the surface temperature of the pads 1 and 2 for the electric thermotherapy device. By applying pressure from above and below, such a laminated state is formed, and pads 1 and 2 for an electric thermotherapy device are produced.

The

heating electrodes

26 and 27 may have a strip shape (rectangular shape). However, as shown in FIG. 6, the

heating electrodes

26 and 27 extend in a longitudinal direction from a predetermined position P _{1 to} P _{4 at} the central portion of the

heating electrodes

26 and 27. It is desirable that the taper is cut out toward the end portions Q1 _to Q4. That is, when the

heating electrodes

26 and 27 are in a strip shape (rectangular shape), the temperature of the end portions in the longitudinal direction of the

heating electrodes

26 and 27 may be high, and the temperature of the central portion may be low. However, as shown in FIG. 6, by cutting out both ends of the

heating electrodes

26 and 27 in a tapered shape, current flows easily in the central region, and current does not easily flow in the end region. Thus, the temperature distribution can be made uniform.

Further, as shown in FIG. 7, each of the pair of

heat generating electrodes

26 and 27 is disposed adjacent to the electrode cover 29 at the center inner portion of the

heat generating electrodes

26 and 27, and the carbon fiber of the heat generating sheet 28. You may make it provide the orthogonal carbon layers 60 and 61 which have orientation in the direction orthogonal to this orientation direction. That is, by having the orthogonal carbon layers 60 and 61 in the central inner portions of the

heat generating electrodes

26 and 27, the impedance of the central portions of the

heat generating electrodes

26 and 27 is reduced, current flows easily, and the temperature distribution is made uniform. can do.

Further, the oscillation electrode 13 may have a plate-like electrode having the same external shape as the electric thermotherapy device pads 1 and 2. As this plate electrode, one having conductivity and excellent thermal conductivity is used, for example, aluminum. In other words, the plate-like electrode functions as a weak current electrode, and heat generated in the heating section 22 can be diffused to make the temperature distribution uniform. Although the flexibility of the pad may be deteriorated by having the plate-like electrode, the flexibility can be improved by using the plate-like electrode as a punching plate, and the pad is brought into close contact with the body part. Is possible.

As described above, in the pads 1 and 2 for the electric thermotherapy device according to the present embodiment, the sticking portion to be stuck to the living body is made of a nonwoven fabric, and the feeling of wearing can be improved by suppressing irritation to the skin. In addition, when the adhesive layer is kept moist by water retention, moisture can be given to the skin, and the energization efficiency from the conductive means can be increased through the retained water. Furthermore, when moisture permeates the skin cells, the current from the conductive means can be efficiently supplied to the gaps between the cells.

The following experiment was conducted on the effect of relaxing the pad surface temperature by the nonwoven fabric. The experiment
(1) In the structure shown in FIG. 5A, the adhesive layer 11 is not provided (hereinafter referred to as only the pad).
(2) One having the structure of FIG. 5A (hereinafter referred to as pad + nonwoven fabric) (the nonwoven fabric contains moisture in advance)
(3) What does not have the nonwoven fabric layer 11a in the structure of FIG. 5 (B) (hereinafter referred to as pad + gel)
Images were taken by thermography.

FIG. 8 is a thermographic image showing the experimental results. FIG. 8A shows a state after completion of preheating, and FIG. 8B shows a state where 10 minutes have elapsed after completion of preheating. Note that FIG. 8 is difficult to distinguish between the high temperature part (40 degrees or more) and the low temperature part (23 degrees or less) for the convenience of drawing (gray scale display), but the inside of the pad is a high temperature region of 32 degrees or more. Suppose the pad exterior is shown as a low temperature region of 28 degrees or less.

As is clear from the results of FIG. 8, the temperature of the (2) pad + nonwoven fabric is suppressed and homogenized (relative to the temperature difference) compared to the case of (1) pad only and (3) pad + gel. is doing. In other words, as in the present invention, by having the adhesive layer 11 and the non-woven fabric layer 11a containing moisture on the pad surface that is in direct contact with the skin, moisture is given while suppressing irritation to the skin, and the temperature is made uniform. Even if a temperature abnormality occurs, the temperature rise can be mitigated and the safety of the user can be ensured. In addition, when moisture penetrates into the network structure of the nonwoven fabric, the energization effect can be enhanced and electrical stimulation can be effectively applied.
