The present invention relates to an electrostatic potential and an interference current combination therapy device that can reduce the cost of manufacturing by miniaturizing the therapy device by sharing a probe for current.

Electro stimulation therapy devices have been developed in various medical device types by applying voltage, current, and resistance as medical technology. Since 1950s, they have been widely used in hospitals, clinics, and homes as physical therapy and medical devices.

Representative electric stimulation treatments include electrostatic potential treatments that induce high potentials by charging high voltages to the human body, and current stimulation treatments that apply minute low frequency (also medium or high frequency) currents to the human body. Among the current stimulation treatments, interference current therapy is to diversify the form of the stimulus by causing the nature (frequency and amplitude) of the current applied to the human body to be changed unevenly.

Potential treatment is to apply a high voltage of about 9000V to the probe in contact with the human body, and to treat the human body charged by the high voltage between the probe and the ground to induce a potential, and to promote metabolism through the activation of cells The blood purification through the blood purification effect, and the effect of increasing the body's immunity is effective.

Interference current treatment stimulates the muscles and nerves of the human body by applying minute low-frequency (also medium or high-frequency) harmless to the human body to relieve pain, treat muscle diseases, promote blood circulation, and massage (physical therapy).

The electrostatic potential and interference current combination therapy device according to the present invention, as shown in the drawings, the first interference current channel 10, the second interference current channel 20, the electrostatic potential induction channel 30, the components of the controller 40 It is roughly divided into.

The first interference current channel 10 and the second interference current channel 20 have a similar configuration and function, and the difference may be that the characteristics (frequency or waveform) of the generated carrier sine wave and the modulated sine wave are different. Is there.

The first interference current channel 10 includes a first carrier oscillator 11, a first modulated oscillator 12, a first modulator 13, a first amplifier 14, a first insulation transformer T1, and a first Probes P1a and P1b are included, and the second interference current channel 20 includes a second carrier oscillator 21, a second modulator oscillator 22, a second modulator 23, and a second amplifier 24. ), A second insulating transformer T2, and second probes P2a and P2b.

For reference, hereinafter, “first” and “second” used to prevent division and confusion between components of the first interference current channel 10 and the second interference current channel 20 are confused with the necessity of the distinction. In situations where it is determined that there is no concern, this will be omitted and explained.

The carrier oscillators 11 and 21 generate the carrier sine waves CSW1 and CSW2 by oscillating the power current supplied from the controller 40.

The modulation oscillators 12 and 22 also oscillate the power supply current supplied from the controller 40 to generate modulation sine waves MSW1 and MSW2 having different properties (eg, frequency and amplitude) from the carrier sine waves CSW1 and CSW2. and,

The modulators 13 and 23 modulate the carrier sine waves CSW1 and CSW2 of the carrier oscillators 11 and 21 and the modulation sine waves MSW1 and MSW2 of the modulation oscillators 12 and 22 to modulate the modulated waves CSW1_M, CSW2_M),

The amplifiers 14 and 24 amplify modulated waves CSW1_M and CSW2_M of the modulators 13 and 23 to adjust intensity.

The isolation transformers T1 and T2 transmit modulated waves CSW1_MA and CSW2_MA that are amplified and output from the amplifiers 14 and 24 and are input to the probes P1a, P1b, P2a and P2b, and then amplified modulated waves. The primary side to which the CSW1_MA and CSW2_MA are input and the secondary side outputting to the probes P1a, P1b, P2a, and P2b are electrically insulated from each other so as to isolate the primary side (ie, the amplifiers 14 and 24) and the modulators 13 and 23. ), Carrier oscillation parts 11, 21, etc.) are protected from the secondary side.

The first probes P1a and P1b and the second probes P2a and P2b are formed in pairs facing each other, and the pair of first probes P1a and P1b and the pair of second probes P2a and P2b, respectively. ) Are arranged to intersect,

Current flowing through the pair of first probes P1a and P1b (ie, the first carrier sine wave CSW1_MAT through the first modulator 13, the first amplifier 14, and the first insulation transformer T1) Currents flowing through the pair of second probes P2a and P2b (ie, the second modulator 23, the second amplifier 24, and the second carrier sine wave CSW2_MAT through the second insulation transformer T2) interfere with each other. To induce an interference current (IC).

The interference current IC induced and generated by the first probes P1a and P1b and the second probes P2a and P2b is characterized by the nature of the current CSW1_MAT flowing through the first probes P1a and P1b and the second probe P2a. , P2b) according to the nature of the current flowing through (CSW2_MAT) has a frequency of 2000Hz ~ 8000Hz (that is, any frequency from low to medium and high frequency) and various waveform intensities to apply various types of electrical stimulation to the human body Deeply into the dermis of the skin and into the muscular nervous system below it.

Although driving of the carrier oscillators 11 and 21 is necessary to induce an interference current IC to a human body, driving of the modulation oscillators 12 and 22 is optional, and the modulation oscillators 12 and 22 are driven. Otherwise, the modulators 13 and 23 may bypass the carrier sine waves CSW1 and CSW2 to the amplifiers 14 and 24 without modulating.

The first carrier oscillator 11, the first modulated oscillator 12, the second carrier oscillator 21, and the second modulated oscillator 22 each comprise one type of carrier sine wave (CSW1, CSW2) and a modulated sine wave (MSW1, In the case where MSW2) can be generated, there are six types of interference currents IC induced and applied to the human body through the first probes P1a and P1b and the second probes P2a and P2b.

That is, when the first first carrier oscillator 11 and the second carrier oscillator 21 are driven, the second first carrier oscillator 11, the second carrier oscillator 21, and the second modulated oscillator 22 are driven. In this case, when the third first carrier oscillator 11, the first modulated oscillator 12, and the second carrier oscillator 21 are driven, the fourth first carrier oscillator 11, the first modulated oscillator 12, and the second When the carrier oscillator 21 and the second modulated oscillator 22 are driven, when the fifth first carrier oscillator 11 and the first modulated oscillator 12 are driven, the sixth second carrier oscillator 21 and the second The modulation oscillator 22 is driven.

Modulated waves CSW1_M and CSW2_M modulated in 13 and 23 may also be referred to as a kind of interference current that is not constant in frequency and magnitude.

The electrostatic potential induction channel 30 has a high voltage through the first probe P1a and P1b or the second probe P2a and P2b or the first probe P1a and P1b and the second probe P2a and P2b. By applying to the electric potential is induced on the skin surface of the human body.

The electrostatic potential induction channel 30 may supply a high voltage to at least one of four probes (ie, two first probes P1a and P1b and two second probes P2a and P2b), but the probe may contact the skin. Rubbing in this condition can cause the probe to fall into contact with the skin (non-contacting) instantaneously, causing a tingling pain in the skin due to a large potential change. Therefore, it is desirable to supply high voltage to all four probes (P1a, P1b, P2a, P2b) to prevent the probe from falling out of the skin (a tingling pain occurs when all probes supplying the high voltage fall from the skin). Do.

The electrostatic potential induction channel 30 boosts a commercial power supply to a high voltage (approximately 9000 V), and the high voltage unit 31 for raising the boosted high voltage to a constant voltage, and the output lines of the high voltage unit 31 have four probes P1a and P1b. Are connected to the input lines of P2a and P2b to prevent the carrier sine waves CSW1_MAT and CSW2_MAT applied by the interference current channel to the pro unit from flowing to the output line of the high voltage unit 31. R3, R4).

The probes P1a, P1b, P2a, and P2b to which the high voltage supplied by the high voltage unit 31 are applied form a grounded ground and an electric field in contact with the human body so as to generate a fine induced current in the human body. That is, the electrostatic potential is induced on the skin surface of the human body.

The interference current protection parts R1, R2, R3, and R4 use resistors having a very large value, so that the carrier sine waves CSW1_MAT and CSW2_MAT do not flow to the output line of the high voltage part 31, and thus the probes P1a and P1b. , P2a, P2b).

In the drawing, if there is no resistance as the interference current protection parts R1, R2, R3, and R4, the two input lines connected to the pair of probes P1a, P1b or P2a, P2b are in a short state and the insulation transformers T1 and T2 are short. Very large current is induced on the secondary side of the c) and causes an electrical accident, but when the resistance is present as the interference current protection units R1, R2, R3, and R4, it is induced to the secondary side of the insulation transformers T1 and T2. The carrier sine waves CSW1_MAT and CSW2_MAT do not flow through the resistors R1, R2, R3, and R4 and are applied to the probes P1a, P1b or P2a, and P2b.

The controller 40 controls the driving of the first interference current channel 10, the second interference current channel 20, and the electrostatic potential induction channel 30.

The controller 50 is connected to the regulator 50, the feedback unit 60, and the operation unit 70.

The regulator 50 regulates the commercial power to supply driving power required for driving the controller 40 and power currents for the carrier oscillators 11 and 21 and the modulation oscillators 12 and 22.

The feedback unit 60 detects the carrier sine waves CSW1_MAT and CSW2_MAT supplied by the insulation transformers T1 and T2 to the probe and feeds them back to the controller 40. Accordingly, the controller 40 sets the set frequency and magnitude. Carrier sine wave (CSW1_MAT, CSW2_MAT) having a control to the carrier oscillator (11, 21), modulation oscillator (12, 22) and amplifiers (14, 24) to be continuously supplied to the probe (P1a, P1b or P2a, P2b) . The feedback unit includes a current transformer for sensing the frequency and intensity of the current output to the secondary output lines of the isolation transformers T1 and T2, and an op amp that amplifies the current sensed by the current transformer and transmits the current to the controller 40. do.

The control unit is for the user's operation, the display unit for showing the current driving state (for example, whether the power supply, electrostatic potential treatment or interference current treatment, the potential of the potential or interference current (IC), etc.) And a setting unit for setting the treatment intensity, and an input key for inputting various command signals of the user.
