Description

[Technical field]

[0001] The present invention relates to a treatment device having first and second electrodes capable of coming into contact with a living body, and applying electrical stimulation based on power supplied from a power source to the living body via the first and second electrodes. [Background technology]

[0002] Japanese Patent Application Laid-Open No. 2014-64735 (Patent Document 1) describes a treatment device that includes a pair of electrodes to be brought into contact with the skin, a first electrical signal generating means for generating a low-frequency first electrical signal and having an output terminal connected to the pair of electrodes, and a second electrical signal generating means for generating a high-frequency second electrical signal and having an output terminal connected to the output terminal of the first electrical signal generating means via a pair of capacitors, and that applies an electrical stimulus to the skin by superimposing the first low-frequency electrical signal and the second high-frequency electrical signal and outputting them to the pair of electrodes.

[0003] This treatment device applies an electrical signal to the skin that is a superimposition of a first low-frequency electrical signal and a second high-frequency electrical signal, making it possible to simultaneously treat a relatively wide area of ​​the skin and a relatively lower part of the skin, and a relatively narrow area of ​​the skin and a relatively upper part of the skin, and also to suppress the development of habituation to the electrical stimulation. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2014-64735 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the treatment device described in the above publication can perform excellent superposition when the orders (number of digits) of the two frequencies are significantly different, for example, when the low-frequency first electrical signal is 100 Hz and the high-frequency second electrical signal is 2 MHz. However, when the orders (number of digits) of the two frequencies are similar and approximate, for example, when the low-frequency first electrical signal is 100 kHz and the high-frequency second electrical signal is 200 kHz, the high-frequency second electrical signal (200 kHz) is short-circuited via the capacitor and interferes with the low-frequency first electrical signal (100 kHz), making superposition impossible.

[0006] The present invention has been made in consideration of the above, and has as its object to provide a treatment device that can output two electrical signals in a well-superimposed manner regardless of the order (number of digits) of the two frequencies. [Means for solving the problem]

[0007] In order to achieve the above object, the treatment device of the present invention employs the following means.

[0008] According to a preferred embodiment of the treatment device of the present invention, the treatment device has first and second leads that can contact a living body, and applies electrical stimulation based on power supplied from a power source to the living body via the first and second leads. The treatment device includes first and second output terminals to which the first and second leads are connected, a first AC driving circuit, a first regulating unit, a second regulating unit, and a second AC driving circuit. The first AC driving circuit has a first input unit to which power from a power source is input, and a first conversion unit connected to the first input unit and the first and second output terminals. The first conversion unit is capable of converting the power input to the first input unit into a first electrical signal of a first frequency and outputting the converted signal. The first regulating unit is disposed between the first input unit and the first output terminal so as to permit a current flow from the first input unit to the first output terminal, while regulating a current flow from the first output terminal to the first input unit. The second regulating unit is disposed between the first input unit and the second output terminal so as to permit a current flow from the first input unit to the second output terminal while regulating a current flow from the second output terminal to the first input unit. The second AC driving circuit has a second input unit to which power from a power source is input, a second conversion unit connected to the second input unit, and first and second output units connected to the second conversion unit. The second AC driving circuit has a first output unit connected between the first regulating unit and the first output terminal, and the second output unit connected between the second regulating unit and the second output terminal. The second conversion unit can convert the power input to the second input unit into a second electric signal of a second frequency higher than the first frequency and output the second electric signal. Here, the first frequency can be in a frequency band of 0.1 Hz to 100 kHz, and the second frequency can be in a frequency band of 200 kHz to 4 MHz.

[0009] According to the present invention, the first and second output parts of the second AC driving circuit are connected between the first and second regulating parts and the first and second output terminals, in other words, the second AC driving circuit is arranged on the high side (high potential side) of the first AC driving circuit, the first and second output parts of the second AC driving circuit are bridged via the first and second regulating parts, and the first input part of the first AC driving circuit is connected between the first and second regulating parts. Therefore, the second electric signal is not short-circuited regardless of the order (number of digits) of the second frequency. That is, the second electric signal is not short-circuited not only when the order (number of digits) of the second frequency deviates from the order (number of digits) of the first frequency, but also when the order (number of digits) of the second frequency is close to the order (number of digits) of the first frequency. As a result, the first and second electric signals do not interfere with each other. As a result, the first and second electric signals can be excellently superimposed and output from the first and second output terminals. In addition, since the configuration is such that two electric signals are output from a pair of output terminals (first and second output terminals), the space required for arranging the output terminals in the first and second electrodes can be reduced compared to a configuration in which a pair of output terminals are arranged corresponding to each electric signal in order to output each of the two electric signals. This allows other elements, such as an ultrasonic vibrator, to be arranged in the freed space, so that a treatment device that can perform treatment by ultrasonic vibration in addition to treatment by electric stimulation while suppressing the device from becoming larger can be realized. In addition, by configuring the second frequency to be in the frequency band of 200 kHz to 4 MHz, heat can be generated, which can warm the living body from deep inside and promote metabolism, thereby providing a body-care effect and a skin-beautifying effect. As a result, by setting the first frequency to, for example, a frequency suitable for Electric Muscle Stimulation (hereinafter referred to as "EMS"), a frequency suitable for electroporation (hereinafter referred to as "EP"), or a frequency suitable for iontophoresis, it is possible to cause muscle movement while warming the living body, or to introduce a beauty serum while warming the living body, thereby further improving the treatment effect while shortening the treatment time.

[0010] According to a further embodiment of the treatment device of the present invention, the first regulating section is a first diode having a first anode and a first cathode. The first anode is connected to the first input section. The first cathode is connected to the first output section. The second regulating section is a second diode having a second anode and a second cathode. The second anode is connected to the first input section. The second cathode is connected to the second output section.

[0011] According to this embodiment, the first and second restricting portions can be easily realized since the orientation of the two diodes is merely determined and arranged.

[0012] According to a further embodiment of the treatment device of the present invention, the first conversion unit includes a first switching element having one end connected to the first output unit and the other end connected to the first output terminal, a second switching element having one end connected to the second output unit and the other end connected to the second output terminal, a third switching element having one end connected to the first output terminal and the other end grounded, a fourth switching element having one end connected to the second output terminal and the other end grounded to ground, and a switching circuit capable of driving the first to fourth switching elements. The second conversion unit includes a transformer having a primary winding connected to the second input unit and a secondary winding connected to the first and second output units and insulated from the primary winding.

[0013] According to this embodiment, it is possible to easily realize a configuration in which an electrical signal from a power source is converted to a first frequency and outputted, and a configuration in which an electrical signal from a power source is converted to a second frequency higher than the first frequency and outputted.

[0014] According to a further embodiment of the treatment device of the present invention, the treatment device further includes a control unit capable of controlling the first conversion unit. The control unit controls the first conversion unit to alternately and repeatedly execute a first state in which the first and fourth switching elements are turned on and the second and third switching elements are turned off, and a second state in which the first and fourth switching elements are turned off and the second and third switching elements are turned on, in a first mode in which power from the power source is supplied to the first input unit. Here, the "first mode" in the present invention preferably includes a mode in which power from the power source is output to the first and second output terminals via the first and second AC drive circuits as a first electrical signal, in addition to a mode in which power from the power source is output to the first and second output terminals with the first and second electrical signals superimposed thereon.

[0015] According to this embodiment, since only the first to fourth switching elements are controlled to be turned on and off, when the first mode is selected, it is possible, with simple control, to convert the power from the power source into a first electrical signal of a first frequency and output it, or to convert the power from the power source into first and second electrical signals of first and second frequencies and superimpose these two electrical signals and output them.

[0016] According to a further aspect of the treatment device of the present invention, in a second mode in which power from the power source is supplied only to the second input section, the control section controls the first conversion section to turn on the first and third switching elements and to turn off the second and fourth switching elements.

[0017] According to this embodiment, since only the first to fourth switching elements are controlled to be on and off, when the second mode is selected, the power from the power source can be converted into a second electrical signal of the second frequency and output with simple control. Effect of the Invention

[0018] According to the present invention, it is possible to provide a treatment device that can satisfactorily superimpose and output two frequencies regardless of the order (number of digits) of the two frequencies. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Next, the best mode for carrying out the present invention will be described with reference to examples. EXAMPLES

[0021] 1, the treatment device 1 according to the present embodiment includes a device main body 2 and a pair of treatment probes 60a, 60b electrically connected to the device main body 2.

[0022] The device main body 2 can be connected to an AC power source 6 via an AC / DC adapter 4, and is driven by power converted to DC by the AC / DC adapter 4. As shown in Fig. 1, the device main body 2 includes an operation unit 8, a display panel 10, a DC / DC converter 12 that converts DC power from the AC / DC adapter 4 into stabilized DC power, a mode switching circuit 20 to which the DC power converted by the DC / DC converter 12 is supplied, a first AC driving circuit 30, a second AC driving circuit 40, and an ultrasonic generating circuit 50 that are driven by the DC power supplied via the mode switching circuit 20, and an electronic control unit 70 that controls the entire device.

The first, fourth, sixth and seventh modes correspond to the "first mode" in the present invention, and the second and fifth modes are examples of implementation configurations corresponding to the "second mode" in the present invention.

[0025] 2, the first AC drive circuit 30 is connected to the mode switching circuit 20 via an input section Ip1, and includes a voltage control circuit 32, an electrode switching circuit 34, and a pair of output terminals T1 and T2. The voltage control circuit 32 adjusts the DC power converted by the DC / DC converter 12 to a voltage with a frequency set by a level switching switch, and then supplies the adjusted DC power to the electrode switching circuit 34. Here, diodes D1 and D2 are respectively arranged between a connection section Cp1 between the voltage control circuit 32 and the electrode switching circuit 34 (in other words, it can be said to be an input section to which a current resulting from the voltage adjusted by the voltage control circuit 32 is input) and the pair of output terminals T1 and T2. The diode D1 is arranged so that the anode is on the connection section Cp1 side and the cathode is on the output terminal T1 side, and the diode D2 is arranged so that the anode is on the connection section Cp1 side and the cathode is on the output terminal T2 side. In other words, the anodes of the diodes D1 and D2 are connected to the voltage control circuit 32, and the cathodes of the diodes D1 and D2 are connected to the drains of the switching elements SW1 and SW3, which will be described later. That is, the diodes D1 and D2 are arranged in such a direction that they allow the current from the connection part Cp1 to flow to the output terminals T1 and T2, while restricting the reverse (current flow into the connection part Cp1). The output terminals T1 and T2 correspond to the "first output terminal" and the "second output terminal" in the present invention, respectively, and the connection part Cp1 is an example of an embodiment corresponding to the "first input part" in the present invention. In addition, the electrode switching circuit 34 is an example of an embodiment corresponding to the "first conversion part" in the present invention. Furthermore, the anode and the cathode of the diode D1 correspond to the "first anode" and the "first cathode" in the present invention, respectively, and the anode and the cathode of the diode D2 are an example of an embodiment corresponding to the "second anode" and the "second cathode" in the present invention, respectively.

[0026] 2, the electrode switching circuit 34 has switching elements SW1, SW2, SW3, and SW4, and a FET drive circuit 36. The electrode switching circuit 34 is an example of an embodiment corresponding to a “first conversion unit” of the present invention.

[0027] In this embodiment, the switching elements SW1, SW2, SW3, and SW4 are configured to use N-channel MOSFETs. As shown in FIG. 2, the switching element SW1 has a drain connected to the cathode of the diode D1 (in other words, the output section 47a of the secondary coil 46b of the transformer 46), a source connected to the output terminal T1, and a gate connected to the output of the FET drive circuit 36. The switching element SW2 has a drain connected to the source of the switching element SW1 (in other words, the output terminal T1), a source grounded to the ground G, and a gate connected to the output of the FET drive circuit 36. That is, the switching elements SW1 and SW2 are connected in series via the output terminal T1. The switching element SW3 has a drain connected to the cathode of the diode D2 (in other words, the output section 47b of the secondary coil 46b of the transformer 46), a source connected to the output terminal T2, and a gate connected to the output of the FET drive circuit 36. The drain of the switching element SW4 is connected to the source of the switching element SW3 (in other words, the output terminal T2), the source is grounded to the ground G, and the gate is connected to the output of the FET drive circuit 36. That is, the switching elements SW3 and SW4 are connected in series via the output terminal T2. Here, "ground" refers to a connection to the ground, which is a reference potential, and is not limited to a connection to earth. The switching element SW1 corresponds to the "first switching element" in the present invention, the switching element SW2 corresponds to the "third switching element" in the present invention, the switching element SW3 corresponds to the "second switching element" in the present invention, and the switching element SW4 corresponds to the "fourth switching element" in the present invention. The diode D1 and the diode D2 are examples of embodiments corresponding to the "first regulation unit" and the "second regulation unit" in the present invention, respectively.

[0028] The FET drive circuit 36 ​​is composed of resistors and diodes (not shown). The FET drive circuit 36 ​​is driven by DC power from the DC / DC converter 12, and applies a voltage to the gates of the switching elements SW1, SW2, SW3, and SW4 to turn these switching elements SW1, SW2, SW3, and SW4 on and off.

[0029] As shown in FIG. 2, the second AC drive circuit 40 is connected to the mode switching circuit 20 via an input section Ip2, and includes an AC control circuit 42, a power control circuit 44, and a transformer 46. The AC control circuit 42 receives an on / off signal and a frequency setting signal from the electronic control unit 70 to control the power control circuit 44. The power control circuit 44 adjusts the DC power converted by the DC / DC converter 12 to a power value set by the level switching switch and a frequency adjusted by the AC control circuit 42, and then supplies the DC power to the transformer 46. The transformer 46 has a primary coil 46a connected to the output of the power control circuit 44, and a secondary coil 46b insulated from the primary coil 46a. The output sections 47a and 47b of the secondary coil 46b are connected to the cathodes of the diodes D1 and D2, respectively, in other words, to the drains of the switching elements SW1 and SW3. That is, the second AC drive circuit 40 is disposed on the high side (high potential side) with respect to the first AC drive circuit 30. The input section Ip2 corresponds to the "second input section" in the present invention, and the output sections 47a and 47b are examples of embodiments corresponding to the "first output section" and the "second output section" in the present invention, respectively. The AC control circuit 42 and the transformer 46 correspond to the "second conversion section" in the present invention, and the primary coil 46a and the secondary coil 46b are examples of embodiments corresponding to the "primary winding" and the "secondary winding" in the present invention, respectively.

[0030] The ultrasonic generating circuit 50 has an oscillation circuit (not shown) that converts the DC power converted by the DC / DC converter 12 into a continuous high-frequency AC signal, and ultrasonic transducers 52a, 52b (see Figs. 1 and 4) that convert the high-frequency AC signal from the oscillation circuit into ultrasonic vibration. The ultrasonic transducers 52a, 52b are passive elements (e.g., piezoelectric elements or piezo elements) that generate natural vibrations when a voltage is applied. The vibration frequency of the ultrasonic transducers 52a, 52b can be, for example, about 1 MHz.

[0031] As shown in FIG. 3, the treatment probes 60a and 60b have main bodies 62a and 62b, conductive probe heads 64a and 64b integrated with the main bodies 62a and 62b, and grip bands 66a and 66b attached to the main bodies 62a and 62b, and are electrically connected to the device main body 2 by power lines L1, L2, L3, and L4 as shown in FIG. 1. For example, the treatment probes 60a and 60b may be O-probe (a product name manufactured by Miyako Chemical Co., Ltd.). The treatment probes 60a and 60b are examples of the embodiment corresponding to the "first lead" and the "second lead" in the present invention, respectively.

[0032] As shown in Fig. 4, the probe heads 64a and 64b have a hollow truncated cone shape made of metal. One end of the power lines L1 and L2 is electrically connected to the inner surfaces 640a and 640b of the peripheral walls of the probe heads 64a and 64b, respectively, and the other end of the power lines L1 and L2 is electrically connected to the output terminals T1 and T2, respectively. In addition, ultrasonic transducers 52a and 52b electrically connected to one end of the power lines L3 and L4 are disposed on the bottom surfaces 642a and 642b of the probe heads 64a and 64b, respectively. The other ends of the power lines L3 and L4 are electrically connected to the output terminals T3 and T4, respectively. In this embodiment, since only one electrode (connection terminal of power lines L1, L2) is arranged on each of inner surfaces 640a, 640b of the peripheral wall of each of probe heads 64a, 64b, the space for arranging ultrasonic transducers 52a, 52b (bottom surfaces 642a, 642b of each of probe heads 64a, 64b) can be satisfactorily secured. This makes it possible to realize a treatment device 1 that can perform treatment by ultrasonic vibration in addition to treatment by electrical stimulation while suppressing the increase in size of device main body 2.

[0033] As shown in Figs. 1 and 2, the electronic control unit 70 is configured as a microprocessor centered on a CPU, and includes a ROM for storing processing programs such as treatment programs (treatment programs for performing only EMS, heat treatment programs for applying only high frequency, treatment programs for applying only ultrasonic vibration, and treatment programs combining these, i.e., programs for performing treatments in the first to seventh modes), a RAM for temporarily storing data, and an input / output port and a communication port (not shown). The electronic control unit 70 receives an on / off signal from a power switch, a set amplitude value (current value, voltage value, power value) and a set frequency from a level switch, a treatment mode signal from a mode switch, a treatment time from a timer (not shown), and the like, via an input port. The electronic control unit 70 also outputs drive signals (switching signals to switching elements SW1, SW2, SW3, SW4) to the first and second AC drive circuits 30 and 40, a drive signal to the ultrasonic generating circuit 50, a mode switching signal to the mode switching circuit, and the like, via an output port. The electronic control unit 70 is an example of an embodiment corresponding to the "control unit" in the present invention.

[0034] Next, the operation of the treatment device 1 configured in this manner, particularly the operation when the treatment device 1 is driven in the first to seventh modes, will be described. Below, the operations from the first mode to the seventh mode will be described in order.

[0035] <First mode> When the practitioner turns on the power switch of the operation unit 8, switches the mode switch to the first mode, and brings the treatment probes 60a, 60b into contact with the body (treatment area) of the patient, the CPU of the electronic control unit 70 drives the treatment device 1 according to the program for EMS treatment stored in the ROM. Specifically, the CPU of the electronic control unit 70 outputs a mode switching signal to switch the mode switching circuit 20 so that power via the DC / DC converter 12 is supplied only to the first AC driving circuit 30, drives and controls the voltage control circuit 32 so that the power via the DC / DC converter 12 becomes a voltage suitable for EMS treatment, and drives and controls the FET driving circuit 36 ​​so that an electrical signal with a frequency of 0.1 Hz to 100 kHz is output from the first and second output terminals T1, T2. The FET drive circuit 36 ​​switches between a first state in which the switching elements SW1 and SW4 are turned on and the switching elements SW2 and SW3 are turned off, and a second state in which the switching elements SW1 and SW4 are turned off and the switching elements SW2 and SW3 are turned on, at a frequency of 0.1 Hz to 100 kHz. As a result, an electrical stimulation suitable for EMS treatment is given to the body (treatment area) of the treated person through the treatment probes 60a and 60b. In other words, it can be said that an electrical signal with a frequency of 0.1 Hz to 100 kHz is generated between the two treatment probes 60a and 60b, and the electrical stimulation is given to the body (treatment area) of the treated person (twin polar type, see FIG. 5). As a result, as shown in FIG. 5, the electrical signal output from the wide area of ​​the two treatment probes 60a and 60b (probe heads 64a and 64b) can give electrical stimulation to the muscle layer (inner muscle) over a wide range.

[0036] <Second mode> When the practitioner turns on the power switch of the operation unit 8, switches the mode switch to the second mode, and brings the treatment probes 60a and 60b into contact with the body (treatment area) of the patient, the CPU of the electronic control unit 70 drives the treatment device 1 according to the program for high-frequency thermal treatment stored in the ROM. Specifically, the CPU of the electronic control unit 70 outputs a mode switching signal to switch the mode switching circuit 20 so that the power through the DC / DC converter 12 is supplied only to the second AC drive circuit 40, drives and controls the power control circuit 44 so that the power through the DC / DC converter 12 is suitable for high-frequency thermal treatment, and drives and controls the AC control circuit 42 and the FET drive circuit 36 ​​so that electrical signals with frequencies of 200 kHz to 4 MHz are output from the first and second output terminals T1 and T2. The FET drive circuit 36 ​​turns on the switching elements SW1 and SW3 and turns off the switching elements SW2 and SW4. As a result, an electrical stimulus suitable for high-frequency thermal treatment is applied to the body (treatment area) of the patient via the treatment probes 60a and 60b. In other words, an electrical signal with a frequency of 200 kHz to 4 MHz is generated between the two treatment probes 60a and 60b, and the electrical stimulus is applied to the body (treatment area) of the patient (twin polar type, see FIG. 5). As a result, heat is generated over a wide range by the electrical signal with a frequency of 200 kHz to 4 MHz output from the wide area of ​​the two treatment probes 60a and 60b (probe heads 64a and 64b), and the living body can be warmed from the deep inside. This can produce a skin-beautifying effect and a slimming effect.

[0037] <Third mode> When the practitioner turns on the power switch of the operation unit 8 and switches the mode switching switch to the third mode, and brings the treatment probes 60a and 60b into contact with the body (treatment area) of the patient, the CPU of the electronic control unit 70 drives the treatment device 1 according to the program for ultrasonic treatment stored in the ROM. Specifically, the CPU of the electronic control unit 70 outputs a mode switching signal to switch the mode switching circuit 20 so that the power through the DC / DC converter 12 is supplied only to the ultrasonic generation circuit 50, and drives and controls the ultrasonic generation circuit 50 so that the power through the DC / DC converter 12 is converted into an electric signal of a frequency (1 MHz to 5 MHz) suitable for ultrasonic treatment and output from the output terminals T3 and T4. This causes the ultrasonic transducers 52a and 52b to vibrate, and the body (treatment area) of the patient is given vibration suitable for ultrasonic treatment via the treatment probes 60a and 60b. In other words, ultrasonic vibrations with a frequency of 1 MHz to 5 MHz are generated between the two treatment probes 60a, 60b and applied to the body (treatment area) of the patient (twin polar type, see Fig. 5). As a result, the ultrasonic vibrations with a frequency of 1 MHz to 5 MHz output from the wide area of ​​the two treatment probes 60a, 60b (probe heads 64a, 64b) can remove old dead skin cells and dirt from the skin over a wide area and tighten the skin.

[0038] <Fourth mode> When the practitioner turns on the power switch of the operating unit 8 and switches the mode changeover switch to the fourth mode and brings the treatment probes 60a, 60b into contact with the body of the person to be treated (treatment area), the CPU of the electronic control unit 70 drives the treatment device 1 in accordance with a program stored in the ROM, specifically, a program for simultaneously performing EMS treatment and high-frequency thermal treatment. More specifically, the CPU of the electronic control unit 70 outputs a mode switching signal to switch the mode switching circuit 20 so that power via the DC / DC converter 12 is supplied to the first and second AC drive circuits 30, 40, drives and controls the voltage control circuit 32 so that the power via the DC / DC converter 12 is a voltage suitable for EMS treatment, drives and controls the FET drive circuit 36 ​​so that an electrical signal having a frequency of 0.1 Hz to 100 kHz is output from the first and second output terminals T1, T2, drives and controls the power control circuit 44 so that the power via the DC / DC converter 12 is power suitable for high-frequency thermal treatment, and drives and controls the AC control circuit 42 so that an electrical signal having a frequency of 200 kHz to 4 MHz is output from the first and second output terminals T1, T2. The FET drive circuit 36 ​​switches between a first state in which the switching elements SW1 and SW4 are turned on and the switching elements SW2 and SW3 are turned off, and a second state in which the switching elements SW1 and SW4 are turned off and the switching elements SW2 and SW3 are turned on, at a frequency of 0.1 Hz to 100 kHz. As a result, an electrical signal in which an electrical signal with a frequency of 0.1 Hz to 100 kHz and an electrical signal with a frequency of 200 kHz to 4 MHz are superimposed is output from the output terminals T1 and T2. That is, an electrical stimulation based on an electrical signal in which an electrical signal with a frequency of 0.1 Hz to 100 kHz and an electrical signal with a frequency of 200 kHz to 4 MHz are superimposed is applied to the body (treatment area) of the person to be treated via the treatment probes 60a and 60b. In other words, an electrical signal in which an electrical signal with a frequency of 1 Hz to 100 kHz and an electrical signal with a frequency of 200 kHz to 4 MHz are superimposed is generated between the two treatment probes 60a, 60b, and an electrical stimulation is given to the body of the person being treated (treatment area) (twin polar type, see Figure 5).As a result, the electrical signals (electrical signals in which an electrical signal with a frequency of 1 Hz to 100 kHz and an electrical signal with a frequency of 200 kHz to 4 MHz are superimposed) output from the wide areas of the two treatment probes 60a, 60b (probe heads 64a, 64b) can be used to heat a wide area from deep inside the living body while providing electrical stimulation to the muscle layer (inner muscle).

[0039] Here, in this embodiment, the output parts 47a, 47b of the second AC drive circuit 40 are connected between the diodes D1, D2 and the output terminals T1, T2, respectively, more specifically, to the connection parts Cp2, Cp3 between the cathodes of the diodes D1, D2 and the drains of the switching elements SW1, SW2. In other words, the second AC drive circuit 40 is arranged on the higher side (high potential side) than the first AC drive circuit 30, the output parts 47a, 47b of the second AC drive circuit 40 are bridged via the diodes D1, D2, and the connection part Cp1 between the voltage control circuit 32 and the electrode switching circuit 34 is arranged between the diodes D1, D2. Therefore, regardless of the frequency order (number of digits) of the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC drive circuit 40, the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC drive circuit 40 will not be short-circuited. That is, not only when the frequency order (number of digits) of the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC driving circuit 40 deviates from the frequency order (number of digits) of the electrical signal (electrical signal suitable for EMS treatment) output from the first AC driving circuit 30 (for example, when the frequency of the electrical signal suitable for EMS treatment is 0.1 Hz and the frequency of the electrical signal suitable for high-frequency thermal treatment is 4 MHz), but also when the frequency order (number of digits) of the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC driving circuit 40 is close to the frequency order (number of digits) of the electrical signal (electrical signal suitable for EMS treatment) output from the first AC driving circuit 30 (for example, when the frequency of the electrical signal suitable for EMS treatment is 100 kHz and the frequency of the electrical signal suitable for high-frequency thermal treatment is 200 kHz), the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC driving circuit 40 will not be short-circuited. This allows the electrical signal suitable for EMS treatment and the electrical signal suitable for high-frequency thermal treatment to be effectively superimposed and output from output terminals T1, T2 without causing interference between the electrical signal suitable for EMS treatment and the electrical signal suitable for high-frequency thermal treatment.

[0040] <Fifth mode> When the practitioner turns on the power switch of the operating unit 8 and switches the mode changeover switch to the fifth mode and brings the treatment probes 60a, 60b into contact with the body of the person to be treated (treatment area), the CPU of the electronic control unit 70 drives the treatment device 1 in accordance with a program stored in the ROM, specifically, a program for simultaneously performing high-frequency thermal treatment and ultrasonic treatment. More specifically, the CPU of the electronic control unit 70 outputs a mode switching signal to switch the mode switching circuit 20 so that the power through the DC / DC converter 12 is supplied to the second AC driving circuit 40 and the ultrasonic generating circuit 50, drives and controls the power control circuit 44 so that the power through the DC / DC converter 12 is suitable for high-frequency hyperthermia treatment, drives and controls the AC control circuit 42 and the FET driving circuit 36 ​​so that an electric signal with a frequency of 200 kHz to 4 MHz is output from the first and second output terminals T1, T2, and drives and controls the ultrasonic generating circuit 50 so that the power through the DC / DC converter 12 is converted into an electric signal with a frequency (1 MHz to 5 MHz) suitable for ultrasonic treatment and output from the output terminals T3, T4. The FET driving circuit 36 ​​turns on the switching elements SW1, SW3 and turns off the switching elements SW2, SW4. As a result, electrical signals with frequencies of 200 kHz to 4 MHz are output from the output terminals T1 and T2, and electrical signals with frequencies of 1 MHz to 5 MHz are output from the output terminals T3 and T4. That is, electrical stimulation based on electrical signals with frequencies of 200 kHz to 4 MHz and ultrasonic vibration based on electrical signals with frequencies of 1 MHz to 5 MHz are applied to the body (treatment area) of the patient through the treatment probes 60a and 60b. In other words, it can be said that electrical signals with frequencies of 200 kHz to 4 MHz and ultrasonic vibrations with frequencies of 1 MHz to 5 MHz are generated between the two treatment probes 60a and 60b, and are applied to the body (treatment area) of the patient (twin polar type, see FIG. 5).As a result, the electrical signals with a frequency of 200 kHz to 4 MHz output from the wide area of ​​the two treatment probes 60a, 60b (probe heads 64a, 64b) and the ultrasonic vibrations with a frequency of 1 MHz to 5 MHz output from a wide range can heat the deep inside of the living body, remove old dead skin cells and dirt, and tighten the skin.

[0041] <6th mode> When the practitioner turns on the power switch of the operating unit 8 and switches the mode changeover switch to the sixth mode and brings the treatment probes 60a, 60b into contact with the body of the person to be treated (treatment area), the CPU of the electronic control unit 70 drives the treatment device 1 according to a program stored in the ROM, specifically, a program for simultaneously performing EMS treatment and ultrasonic treatment. More specifically, the CPU of the electronic control unit 70 outputs a mode switching signal to switch the mode switching circuit 20 so that power via the DC / DC converter 12 is supplied to the first AC driving circuit 30 and the ultrasonic generating circuit 50, drives and controls the power control circuit 44 so that the power via the DC / DC converter 12 is suitable for EMS treatment, drives and controls the voltage control circuit 32 and the FET driving circuit 36 ​​so that an electrical signal having a frequency of 0.1 Hz to 100 kHz is output from the first and second output terminals T1, T2, and drives and controls the ultrasonic generating circuit 50 so that the power via the DC / DC converter 12 is converted into an electrical signal having a frequency (1 MHz to 5 MHz) suitable for ultrasonic treatment and output from the output terminals T3, T4. The FET drive circuit 36 ​​switches between a first state in which the switching elements SW1 and SW4 are turned on and the switching elements SW2 and SW3 are turned off, and a second state in which the switching elements SW1 and SW4 are turned off and the switching elements SW2 and SW3 are turned on, at a frequency of 0.1 Hz to 100 kHz. As a result, an electrical signal with a frequency of 0.1 Hz to 100 kHz is output from the output terminals T1 and T2, and an electrical signal with a frequency of 1 MHz to 5 MHz is output from the output terminals T3 and T4. That is, electrical stimulation based on the electrical signal with a frequency of 0.1 Hz to 100 kHz and ultrasonic vibration based on the electrical signal with a frequency of 1 MHz to 5 MHz are applied to the body (treatment area) of the person to be treated via the treatment probes 60a and 60b. In other words, an electrical signal having a frequency of 0.1 Hz to 100 kHz is alternated between the two treatment probes 60a, 60b, and ultrasonic vibrations having a frequency of 1 MHz to 5 MHz are generated and applied to the body of the person being treated (treatment area) (twin polar type, see Figure 5).As a result, the electrical signals with a frequency of 0.1 Hz to 100 kHz output from the wide areas of the two treatment probes 60a, 60b (probe heads 64a, 64b) and the ultrasonic vibrations with a frequency of 1 MHz to 5 MHz output from the wide area can electrically stimulate the muscle layer (inner muscle) over a wide area, removing old dead skin cells and dirt from the skin and tightening the skin.

[0042] <7th mode> When the practitioner turns on the power switch of the operation unit 8, switches the mode switching switch to the seventh mode, and brings the treatment probes 60a, 60b into contact with the body (treatment area) of the patient, the CPU of the electronic control unit 70 drives the treatment device 1 according to a program stored in the ROM, specifically, a program for simultaneously performing EMS treatment, high-frequency thermotherapy, and ultrasonic treatment. More specifically, the CPU of the electronic control unit 70 outputs a mode switching signal to switch the mode switching circuit 20 so that power via the DC / DC converter 12 is supplied to the first AC driving circuit 30, the second AC driving circuit 40, and the ultrasonic generating circuit 50, drives and controls the power control circuit 44 so that the power via the DC / DC converter 12 becomes power suitable for EMS treatment, and controls the voltage control circuit 32 and the FET drive circuit 44 so that an electrical signal with a frequency of 0.1 Hz to 100 kHz is output from the first and second output terminals T1, T2. The FET drive circuit 36 ​​drives and controls the power control circuit 44 so that the power through the DC / DC converter 12 becomes power suitable for high-frequency hyperthermia treatment, drives and controls the AC control circuit 42 so that an electrical signal with a frequency of 200 kHz to 4 MHz is output from the first and second output terminals T1, T2, and drives and controls the ultrasonic generation circuit 50 so that the power through the DC / DC converter 12 is converted into an electrical signal with a frequency (1 MHz to 5 MHz) suitable for ultrasonic treatment and output from the output terminals T3, T4. The FET drive circuit 36 ​​switches between a first state in which the switching elements SW1, SW4 are turned on and the switching elements SW2, SW3 are turned off, and a second state in which the switching elements SW1, SW4 are turned off and the switching elements SW2, SW3 are turned on, at a frequency of 0.1 Hz to 100 kHz. As a result, an electrical signal in which an electrical signal with a frequency of 0.1 Hz to 100 kHz and an electrical signal with a frequency of 200 kHz to 4 MHz are superimposed is output from output terminals T1 and T2, and an electrical signal with a frequency of 1 MHz to 5 MHz is output from output terminals T3 and T4.That is, through the treatment probes 60a and 60b, electrical stimulation based on an electrical signal in which an electrical signal with a frequency of 0.1 Hz to 100 kHz and an electrical signal with a frequency of 200 kHz to 4 MHz are superimposed, and ultrasonic vibration based on an electrical signal with a frequency of 1 MHz to 5 MHz is applied to the body (treatment area) of the patient. In other words, between the two treatment probes 60a and 60b, an electrical signal in which an electrical signal with a frequency of 1 Hz to 100 kHz and an electrical signal with a frequency of 200 kHz to 4 MHz are superimposed, and ultrasonic vibration with a frequency of 1 MHz to 5 MHz is generated and applied to the body (treatment area) of the patient (twin polar type). As a result, the electrical signals (electrical signals in which an electrical signal with a frequency of 1 Hz to 100 kHz and an electrical signal with a frequency of 200 kHz to 4 MHz are superimposed) output from the wide areas of the two treatment probes 60a, 60b, and the ultrasonic vibrations (1 MHz to 5 MHz) output from a wide area, can heat the deep inside of the living body over a wide area, while providing electrical stimulation down to the muscle layer (inner muscle), and can also remove old dead skin cells and dirt from the skin and tighten the skin.

[0043] According to the treatment device 1 of the present embodiment described above, the output parts 47a, 47b of the second AC drive circuit 40 are connected between the diodes D1, D2 and the output terminals T1, T2, respectively, more specifically, to the connection parts Cp2, Cp3 between the cathodes of the diodes D1, D2 and the drains of the switching elements SW1, SW2. In other words, the second AC drive circuit 40 is arranged on the high side (high potential side) of the first AC drive circuit 30, the output parts 47a, 47b of the second AC drive circuit 40 are bridged via the diodes D1, D2, and the connection part Cp1 between the voltage control circuit 32 and the electrode switching circuit 34 is arranged between the diodes D1, D2. Therefore, regardless of the frequency order (number of digits) of the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC drive circuit 40, the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC drive circuit 40 will not be short-circuited. That is, not only when the frequency order (number of digits) of the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC driving circuit 40 deviates from the frequency order (number of digits) of the electrical signal (electrical signal suitable for EMS treatment) output from the first AC driving circuit 30 (for example, when the frequency of the electrical signal suitable for EMS treatment is 0.1 Hz and the frequency of the electrical signal suitable for high-frequency thermal treatment is 4 MHz), but also when the frequency order (number of digits) of the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC driving circuit 40 is close to the frequency order (number of digits) of the electrical signal (electrical signal suitable for EMS treatment) output from the first AC driving circuit 30 (for example, when the frequency of the electrical signal suitable for EMS treatment is 100 kHz and the frequency of the electrical signal suitable for high-frequency thermal treatment is 200 kHz), the electrical signal (electrical signal suitable for high-frequency thermal treatment) output from the second AC driving circuit 40 will not be short-circuited. This allows the electrical signal suitable for EMS treatment and the electrical signal suitable for high-frequency thermal treatment to be excellently superimposed without interfering with each other and output from the output terminals T1, T2.Furthermore, since the orientation of the two diodes D1, D2 is simply specified and positioned, the electrical signal output from the first AC driving circuit 30 (electrical signal suitable for EMS treatment) and the electrical signal output from the second AC driving circuit 40 (electrical signal suitable for high-frequency thermal treatment) can be superimposed, and a circuit can be easily realized in which no short circuit occurs in the electrical signal output from the second AC driving circuit 40 (electrical signal suitable for high-frequency thermal treatment).

[0044] In this embodiment, a pair of treatment probes 60a, 60b is used, but this is not limited thereto. For example, as shown in FIG. 6, a modified treatment instrument 100 may be used, which includes a treatment probe 60a and a treatment glove 160. The modified treatment instrument 100 has the same configuration as the treatment instrument 1 of the embodiment, except that the treatment probe 60b is replaced with the treatment glove 160, and the output terminal T4 and the power line L4 are deleted. Therefore, the same reference numerals are used for the configuration of the modified treatment instrument 100 that is the same as the configuration of the treatment instrument 1 of this embodiment, and detailed description thereof will be omitted.

[0045] The treatment glove 160 is made of a conductive fiber material mixed with silver, copper, etc. so that the electrical resistance is 1 kΩ or less. By using the treatment glove 160 as a conductor, treatment can be performed in a state where it fits the shape of the treatment area. This allows for detailed and efficient treatment. The treatment device 100 of the modified example also has the same action and effect as the treatment device 1 of the embodiment, for example, in each mode, an electric signal (an electric signal having a frequency of 0.1 Hz to 100 kHz suitable for EMS treatment or an electric signal having a frequency of 200 kHz to 4 MHz suitable for high-frequency thermal treatment) or an ultrasonic vibration (a vibration having a frequency of 1 MHz to 5 MHz) can be generated between the treatment probe 60a and the treatment glove 160 and applied to the body (treatment area) of the person to be treated (twin polar, see FIG. 7), and when the frequency order (number of digits) of the electric signal (electric signal suitable for high-frequency thermal treatment) output from the second AC drive circuit 40 deviates from the frequency order (number of digits) of the electric signal (electric signal suitable for EMS treatment) output from the first AC drive circuit 30 (for example, when the frequency of the electric signal suitable for EMS treatment is 0 This advantageous effect can be achieved not only when the frequency order (number of digits) of the electrical signal suitable for EMS treatment output from the second AC driving circuit 40 (electrical signal suitable for high-frequency thermal treatment) is close to the frequency order (number of digits) of the electrical signal suitable for EMS treatment output from the first AC driving circuit 30 (electrical signal suitable for EMS treatment) (for example, when the frequency of the electrical signal suitable for EMS treatment is 100 kHz and the frequency of the electrical signal suitable for high-frequency thermal treatment is 200 kHz), but also when the frequency order (number of digits) of the electrical signal suitable for EMS treatment and the electrical signal suitable for high-frequency thermal treatment are excellently superimposed and output from the output terminals T1, T2 without causing the electrical signals suitable for EMS treatment and the electrical signals suitable for high-frequency thermal treatment to interfere with each other.

[0046] In the present embodiment and the above-mentioned modified example, the electric signal output from the first AC drive circuit 30 is an electric signal suitable for EMS treatment, but this is not limited thereto. For example, the electric signal output from the first AC drive circuit 30 may be an electric signal suitable for electroporation (EP) treatment for permeating a living body with a beauty ingredient, or may be an electric signal suitable for iontophoresis treatment for permeating a living body with a beauty ingredient. In this case, the voltage control circuit 32 and the FET drive circuit 36 ​​may be driven and controlled so that the power through the DC / DC converter 12 has a voltage and frequency suitable for EP treatment or iontophoresis treatment. In addition to the first AC drive circuit 30, a drive circuit dedicated to EP treatment or a drive circuit dedicated to iontophoresis treatment may be provided to perform EP treatment or iontophoresis treatment. In this case, the drive circuit dedicated to EP treatment or the drive circuit dedicated to iontophoresis treatment may be connected to the DC / DC converter 12 via a mode switching circuit.

[0047] In the present embodiment and the above-described modified example, the configuration includes a pair of treatment probes 60a, 60b, or the configuration includes the treatment probe 60a and the treatment glove 160, but is not limited thereto. For example, the configuration may include the treatment probe 60a and a conductive pad, a pair of treatment gloves, or the configuration may include the treatment glove 160 and a conductive pad.
