Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a thermal low-frequency treatment lead for performing low-frequency treatment while warming, and a low-frequency treatment device including the lead.
[0002]
[Prior art]
A thermal low-frequency treatment lead is applied to a treatment site in order to perform treatment by applying a low-frequency current to the treatment site while warming the treatment site of a living body. For example, in order to warm the treatment site, One surface of a single insulating layer (resin sheet) is a stainless steel electrode (thermal electrode) that generates heat and a stainless steel electrode (low frequency current electrode) that conducts electricity to a conductive layer (for example, a carbon layer). There is something formed.
[0003]
In this conductor, a resin sheet is attached to an adhesive pad via a carbon layer, and a low frequency current electrode and a heating electrode are formed on the surface of the resin sheet opposite to the carbon layer side. The electrode for low frequency current extends linearly in the center of the resin sheet, and the electrode for heating is continuously formed in a polygonal line pattern so as not to cross (contact) the electrode for low frequency current. According to this conductor, the conductive layer is energized by the low frequency current electrode, and the heating electrode generates heat by its own resistance.
[0004]
However, since the heating electrode is made of stainless steel, the temperature responsiveness to the energization time is poor. For example, if the room temperature is 20 ° C. and the maximum heating temperature is 43 ° C., it takes a long time for the temperature of the conductor to reach 43 ° C. after the heating electrode is energized. Usually, the low frequency treatment has a maximum time of about 15 minutes, so if it takes time to reach 43 ° C., the treatment is almost over when it finally gets warm, and there is no point in heating.
[0005]
For this reason, there is an electrode device for a low frequency treatment device (Japanese Utility Model Publication No. 6-27168) in which the heat generation layer is made of a PTC (positive temperature characteristic) material. In the electrode device described in this publication, a heater portion is configured by a heat generating layer made of a PTC material and an electrode (thermal electrode) that supplies current to the heat generating layer, and a conductive layer and an electrode that supplies current to the conductive layer ( The low frequency current electrode) constitutes a low frequency treatment unit.
[0006]
As is well known, PTC (Positive Temperature Coefficient) has a resistance value that increases with an increase in temperature, and a conductor whose resistance value suddenly increases at about 43 ° C., for example, is selected.
According to this electrode device, the resistance value is low near room temperature (20 ° C.), the temperature rapidly rises due to energization, the current is suppressed by increasing the resistance value when it approaches 43 ° C., and substantially when the temperature exceeds 43 ° C. Current is cut off, heat generation stops, heating can be prevented, and the temperature can be kept substantially constant at 43 ° C.
[0007]
[Problems to be solved by the invention]
However, in the electrode device of the above publication, the heater unit and the low-frequency treatment unit are not only configured on separate resin sheets (insulating sheets), but also the heater unit and the low-frequency unit using pin members and power terminals. Since it is a structure that conducts with the treatment section, there are the following problems (1) and (2).
(1) The number of resin sheets to be used increases. As a whole, the electrode device becomes thicker, the bending force becomes harder (elasticity deteriorates), the fit to the treatment site not only deteriorates, but it is also detachable from the treatment site. It becomes weak against the bending force applied.
{Circle around (2)} The structure is complicated, manufacturing takes time, and the cost increases.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments.
1 and 2 are cross-sectional views schematically showing an example of the structure of the thermal low-frequency treatment lead of claims 2 and 3, respectively. However, in FIG. 1 and FIG. 2, each layer is shown separately for the sake of clarity, but each layer is actually in contact.
[0018]
The conductor shown in FIG. 1 is provided with a low-frequency current electrode and a pair of heating electrodes on one side of the insulating layer (surface on the conductive layer side). Adhesive pad (gel pad) 10 to be attached, conductive layer (carbon layer) 11, insulating layer (resin sheet) 12, PTC layer 13, and carbon layer of another insulating layer (resin sheet) 16 An electrode sheet 17 formed on the surface on the 11 side so that the low frequency current electrode 14 energizing the carbon layer 11 and the pair of positive and negative heating electrodes 15 energizing the PTC layer 13 are not in contact with each other; Are sequentially laminated.
[0019]
In this conductor, both the carbon layer 11 and the PTC layer 13 are provided on the adhesive pad 10 side, but both the layers 11 and 13 are insulated by the resin sheet 12 and are in a non-contact state. The low frequency current electrode 14 is in contact with the carbon layer 11 through the conductive portion 11 a of the carbon layer 11 protruding through the hole 12 a formed in the resin sheet 12, and the heating electrode 15 is in direct contact with the PTC layer 13. The resin sheets 12 and 16 are made of PET film, polyimide film, cloth, etc., and the electrodes 14 and 15 are made of, for example, copper foil.
[0020]
As an example of the thickness of each layer in this conductor, the thickness of the adhesive pad 10 is 2 mm, the thickness of the carbon layer 11 is 40 μm, the thickness of the resin sheet 12 is 50 μm, the thickness of the PTC layer 13 is 40 μm, The electrodes 14 and 15 each have a thickness of 18 μm, the resin sheet 16 has a thickness of 50 μm, and the heat insulating sheet 18 has a thickness of 1.5 mm.
The conductor shown in FIG. 2 is one in which an electrode for low frequency current is provided on one surface (surface on the conductive layer side) of the insulating layer, and an electrode for heating is provided on the other surface (surface on the opposite side). The low-frequency current electrode 22 for energizing the carbon layer 21 is formed on the carbon layer 21 side surface of the adhesive pad 20, the carbon layer 21, and the resin sheet 23, which are attached to the biological surface from the application side of the biological surface. Then, an electrode sheet 25 in which a pair of heating electrodes 24 energizing the PTC layer 26 is formed on the opposite surface, a PTC layer 26, a resin sheet 27, and a heat insulating sheet 28 are laminated in order.
[0021]
For example, the thickness of each layer of the conductor is 2 mm for the adhesive pad 20, 40 μm for the carbon layer 21, 18 μm for the low frequency current electrode 22, 50 μm for the resin sheet 23, The thickness of the heating electrode 24 is 18 μm, the thickness of the PTC layer 26 is 40 μm, the thickness of the resin sheet 27 is 50 μm, and the thickness of the heat insulating sheet 28 is 1.5 mm.
[0022]
Each element of the type of conductor shown in FIG. 1 will be further described. The adhesive pad 10 is the same as that used for the conventional low frequency treatment device, and the carbon layer 11 attached to the adhesive pad 10 has a rectangular shape as shown in FIG. And has protruding conductive portions 11a at the edges of the two sides. The resin sheet 12 shown in FIG. 3B is larger than the carbon layer 11 and has a hole 12 a at a position corresponding to the conduction portion 11 a of the carbon layer 11.
[0023]
The PTC layer 13 of FIG. 4A has a mushroom shape (spade shape) according to the pattern of the heating electrode 15 of the electrode sheet 17 of FIG. 4B. The electrode sheet 17 has the same shape and size as the resin sheet 12, and a low frequency current electrode 14 and a pair (positive and negative) heating electrodes 15 are formed on one side. The low frequency current electrode 14 extends along the peripheral portions of the two sides of the rectangular resin sheet 16, and has contact portions 14a at two locations. The contact portion 14a is in contact with the conducting portion 11a of the carbon layer 11 through the hole 12a of the resin sheet 12, and the carbon layer 11 and the low-frequency current electrode 14 are conducted.
[0024]
The heating electrode 15 includes a positive electrode pattern and a negative electrode pattern. The positive and negative patterns here are branched and extended so as not to contact each other alternately in the vertical direction of the drawing. Corresponding to this positive / negative pattern, the PTC layer 13 has a shape as shown in FIG. 4A, and the PTC layer 13 is in contact with the pair of heating electrodes 15 but the low frequency current electrode 14. Do not touch. Accordingly, when the pair of heating electrodes 15 are energized, the PTC layer 13 generates heat.
[0025]
In this electrode sheet 17, the PTC layer 13 generates heat by energizing the heating electrode 15, but the conductor tends to warp toward the heat insulating sheet 18 with the generation of heat. However, if the low frequency current electrode 14 is formed in a pattern as shown in the figure, it is possible to prevent warping. That is, when the positive / negative pattern of the heating electrode 15 is as shown in FIG. 4B, the warping tends to curve the left and right end portions of the electrode sheet 17 toward the heat insulating sheet 18 side. In response to this warp, when the low frequency current electrode 14 is formed in a pattern as shown in the drawing, that is, with respect to a plurality of positive and negative linear patterns of the heating electrode 15 extending in the vertical direction of the drawing, When the pattern of the low-frequency current electrode 14 is formed in a direction (left-right direction) intersecting the direction (vertical direction), the pattern of the low-frequency current electrode 14 acts so as to cancel out the warp. Can be prevented.
[0026]
FIG. 5 shows another example of the pattern of the PTC layer 13, the low-frequency current electrode 14, and the heating electrode 15. The low-frequency current electrode 14 in FIG. 5B extends linearly at the center of the resin sheet 16, and positive and negative patterns of the heating electrode 15 are formed on both sides of the low-frequency current electrode 14. Here, a plurality of positive and negative linear branch patterns extend in the vertical direction of the drawing, and the pattern of the low-frequency current electrode 14 exists in a direction (left-right direction) that intersects (perpendicularly) the vertical direction, It has a structure that prevents warpage of the conductor due to heat generation. In FIG. 5 (b), the contact portion with the carbon layer 11 is not shown in the low frequency current electrode 14, but the contact portion is provided at an appropriate place (for example, one in the center or one on the left and right), Conductivity with the carbon layer 11 is measured. Then, the PTC layer 13 divided into two as shown in FIG. 5A corresponding to the positive and negative patterns of the heating electrode 15 is used.
[0027]
Here, the difference between the electrode patterns in FIGS. 4 and 5 will be described. In the type of conductor shown in FIG. 1, as shown in FIG. 6A, the PTC layer 13 is present in addition to the resin sheet 12 between the carbon layer 11 and the low-frequency current electrode 14. In order to bring the conductive portion 11 a of the layer 11 into contact with the electrode 14, the PTC layer 13 needs to have a printing loss of width W (interval from the hole 12 a of the resin sheet 12 to the edge of the PTC layer 13). That is, if the thickness of the resin sheet 12 is 50 μm and the thickness of the PTC layer 13 is 40 μm, the distance between the carbon layer 11 and the electrode 14 is 90 μm, and therefore the carbon layer 11 and the electrode 14 are passed through this 90 μm distance. Is required to have a printing loss of width W.
[0028]
On the other hand, in the conventional conductor having the stainless steel electrode, as shown in FIG. 6 (b), there is no PTC layer, so there is no need for the printing loss of the PTC layer. If the thickness is 50 μm, the conductive portion 11 a of the carbon layer 11 may be brought into contact with the stainless steel low-frequency current electrode 14 ′ through the hole 12 a of the 50 μm resin sheet 12.
[0029]
As described above, in the type of conductor shown in FIG. 1, since there is a printing loss of the PTC layer 13, when the low frequency current electrode 14 is located at the center as shown in FIG. The pattern formation region is narrowed, and the area of the PTC layer 13 is accordingly reduced, which is disadvantageous in terms of heat generation efficiency. However, if the low-frequency current electrode 14 is provided at the end as shown in FIG. 4B, the printing loss of the PTC layer 13 can be brought into the space at the end of the resin sheet 16, so The pattern forming region of the electrode 15 can be secured widely and the area of the PTC layer 13 is increased, which is advantageous in terms of heat generation efficiency.
[0030]
Next, each element of the type of conductor shown in FIG. 2 will be further described. In this type of conductor, a plan view of the portion where the electrode sheet 25 and the PTC layer 26 are provided in FIG. 7 as viewed from the heat insulating sheet 28 side (arrow A) is shown in FIG. A plan view viewed from the 20 side (arrow B) is as shown in FIG. However, the resin sheet 27 is omitted.
[0031]
In FIG. 8A, the heating electrode 24 is formed in a positive / negative pattern as shown on one surface of the resin sheet 23 in the electrode sheet 25, and the PTC layer 26 is in contact with the heating electrode 24 of this pattern. Is formed. On the other hand, the low frequency current electrode 22 is formed in the same pattern as the heating electrode 24 on the other surface of the resin sheet 23, and the carbon layer 21 is formed in contact with the low frequency current electrode 22 of this pattern. Yes. The patterns of the low-frequency current electrode 22 and the heating electrode 24 are shown in the same direction in FIGS. 8A and 8B, but the direction of the arrow is the opposite direction (up and down direction). It is point-symmetric with respect to the center of the resin sheet 23, and extends in directions that intersect (orthogonal) each other.
[0032]
According to the pattern of the low-frequency current electrode 22 and the heating electrode 24, the warp of the conductor due to the heat generation of the PTC layer 26 can be prevented as in the case of the conductor of the type shown in FIG. That is, since the heating electrode 24 is a pattern extending in an oblique direction of the drawing, if the pattern of the low-frequency current electrode 22 is formed in a direction intersecting the pattern (perpendicular direction), that is, the pattern of the electrodes 22 and 24. Is formed symmetrically with respect to the center of the resin sheet 23, warping of the conductor can be prevented.
[0033]
The patterns of the low-frequency current electrode 22 and the heating electrode 24 are preferably as similar as possible in point symmetry. That is, in the manufacturing process of the conductor, in the process of forming the PTC layer 26, after printing the PTC, it is baked at a high temperature for about 1 hour, but warping may also occur at this time, so that this can be prevented. However, it is desirable that the patterns of the electrodes 22 and 24 be as much as possible as shown in FIGS.
[0034]
FIG. 9A shows a plan view (figure on the adhesive pad side) of the whole of the thermal low-frequency treatment lead constructed as described above, and FIG. 9B shows a side view thereof. The conductor 30 shown here has an adhesive pad 32 attached to an adhesive pad attaching portion 31, and is used by attaching the adhesive pad 32 to the surface of a living body. The adhesive pad pasting portion 31 includes a carbon layer 11, a resin sheet 12, a PTC layer 13, an electrode sheet 17, and a heat insulating sheet 18 in the type of conductor shown in FIG. 1, and the carbon layer 21 in the type of conductor shown in FIG. , Electrode sheet 25, PTC layer 26, resin sheet 27, and heat insulating sheet 28.
[0035]
According to such a conductor 30, in the type of FIG. 1, the low-frequency treatment unit composed of the low-frequency current electrode 14 and the carbon layer 11 and the heating electrode 15 are provided on one side of one resin sheet 16. 2 and a PTC layer 13 is provided. In the type of FIG. 2, a low frequency treatment unit composed of a low frequency current electrode 22 and a carbon layer 21 is provided on one surface side of one resin sheet 23. Since the heater part composed of the heating electrode 24 and the PTC layer 26 is provided on the other side, compared to the conventional conductor in which the low-frequency treatment part and the heater part are respectively formed on separate resin sheets, However, the number of necessary resin sheets is reduced, the thickness of the conductor is reduced accordingly, and the bending stress is increased.
[0036]
A low-frequency treatment device including such a conductor 30 is, for example, as shown in FIG. The treatment device shown here is the same as the conventional one, and a main body 40 having an electric circuit and switches for generating a low-frequency current, and a pair of conductors having the above-described structure connected to the main body 40 by lead wires 41. And a child 30. The main body 40 has a power / power dial 50 for turning on / off the power and changing the strength of the low frequency current, a strength display 51 for displaying the power on / off and the strength of the low frequency current, A speed changeover switch 52 for switching the cycle of the low frequency output to fast / slow, an output display 53 that blinks in synchronization with the low frequency output, and heating the conductor 30 by turning on / off the power to the conductor 30 There are provided a heat switch 54 for turning on and a heat display 55 that is turned on when the heat is output.
[0037]
The main body 40 and the conductor 30 are connected by inserting a conductor plug 57 attached to one end of the lead wire 41 into the output port 56 of the main body 40. An AC adapter 59 is connected to the main body 40 via an AC adapter jack 58.
In this low-frequency treatment device, as shown in FIG. 11, the conductor 30 is attached to the treatment site 60 of the living body during treatment. At this time, since the conductor 30 is thin and excellent in elasticity, even when the treatment site 60 is a curved surface, the fitting property to the curved surface is good and can be surely adhered to any treatment site 60. . Also, as shown in FIG. 12, when the conductor 30 is attached to and detached from the treatment site 60 (particularly when the conductor 30 is removed), bending force is applied to the conductor 30, but the conductor 30 is thin and bent. Since it is strong against stress, breakage due to bending can be prevented.
[0038]
In the above embodiment, as a structure for preventing the warp of the conductor, in the conductor of the type shown in FIG. 1, the pattern direction of the low-frequency current electrode 14 and the branch pattern direction of the heating electrode 15 are crossed, and FIG. In this type of conductor, the pattern of the low-frequency current electrode 22 and the pattern of the heating electrode 24 are provided point-symmetrically with respect to the center of the resin sheet 23, but the following structure may be adopted. That is, in any of the types of conductors shown in FIGS. 1 and 2, the resin sheets 16 and 23 of the electrode sheets 17 and 25 are fibrous because they are made of PET film, polyimide film, cloth, or the like as described above. Therefore, even if the fiber direction of the resin sheets 16 and 23 and the branch pattern direction of the heating electrodes 15 and 24 are crossed, the warp of the conductor can be prevented by the same action.
