The present invention relates to a multifunctional physical therapy device for both high-frequency thermal therapy and low-frequency stimulation therapy.

As a physical therapy device by electric stimulation which has relieved fatigue, relieved pain such as neuralgia, muscular pain, arthritis, and physical therapy by stimulating the pain part of the body such as abdomen, joint, shoulder, etc., there are high frequency and low frequency therapy device, ultrasonic treatment device, A treatment device, and a vibration treatment device by vibration.

It is a device that generates deep heat by applying high frequency to body part. High frequency physical therapy device is used for various pain relief and treatment, and it is effective for the management of obesity and skin care because it has the function of decomposing and discharging fat cells.

In addition, low-frequency physiotherapy device also attaches a low-frequency generator of anode and cathode to a stimulation device, and when low-frequency electric stimulation is applied to the skin, stimulates the skin surface and internal tissues to promote blood circulation and fatigue recovery of skin surface and tissue, And physical therapy functions to improve the health.

However, in a high-frequency physical therapy apparatus using a high-frequency RF output signal and applying it to a human body, the output level is unstable and congestion may occur due to the use of a high-voltage current. Accordingly, a spark due to a high voltage occurs between the human body and the electrode There is a problem that the electrical stability in use is not ensured due to an image or an instantaneous electric shock from an improper high-frequency output generated from a high-frequency ceramics, etc., thereby causing a serious danger to the human body.

A high frequency therapeutic electrode 260 (high frequency human body output unit) that provides a stimulus by applying a current to a conductive electrode which is in direct contact with a human body and contacts the human body, The use of the push-pull converter of the high-frequency output section makes it possible to obtain a stable waveform and output.

As a result, in the present invention, as an output monitoring device in which the MCU 100 is sensed by human body contact with the human body from the high-frequency therapeutic electrode (high frequency human body output unit) 260, the use sensing resistor A is sensed by a rectifying unit A The abnormal operation state and the current flow are continuously monitored in real time through the sensing input A, and when the ceramic is completely contacted with the skin by the control of the MCU 100, the power is increased to the energy required for the operation, When it is contacted or separated from the human body, the power is reduced by the control of the MCU 100, so that the electric current is not applied to the human body by a certain level or the electric stability is improved by stopping the operation of the device , It is possible to prevent unnecessary energy from being transmitted to the patient, Or image, thereby implementing a multifunction safety system of a physical therapy apparatus according to the intelligent skin feedback system for preventing the side effects, such as overheating.

The low frequency output unit 300 independently connected to an MCU (Micro Control Unit) 100 is a circuit device for generating and supplying a low frequency signal for applying a low frequency electrical stimulation signal to the affected part of the human body, unit (100).

The low frequency part 120 of the low frequency output part 300 is electrically connected to a pulse generating part and a low frequency power part for generating a low frequency reference waveform pulse, which is similar to the high frequency output part.

  The low frequency output unit 300 mixes a carrier signal and an input signal SIGNAL of a microcontroller (MCU) 100 to perform soft waveform output to a sensitive or fragile skin and performs AM modulation (MIXER) 310 for converting a low frequency signal, which is an AM modulation signal from the mixer (MIXER) 310, into a low frequency signal, A low frequency transformer 330 for adjusting the magnitude of a low frequency signal amplified by the LF amplifier 320 and outputting the waveform to a low frequency therapeutic magnet 360 in accordance with a skin procedure, A relay B (low-frequency switch unit) 340, which is switched by the output signal of the low-frequency transformer 330 and selectively supplies power to the patient, A rectifying section B 350 for rectifying the used sensing resistor B to DC as a current detecting resistor of a user interface for measuring and sensing the used power of the low frequency therapeutic ceramics to be flowed, (Low frequency human body output unit) 360 for applying a stimulus to a subject.

 The low frequency output unit 300 is an output monitoring unit that is sensed by the MCU 100 in accordance with whether the human body touches the human body from the low frequency therapeutic electrode 360 as in the case of the high frequency output unit 200, B (360), the abnormal operation state and the current flow are continuously monitored in real time through the sensing input B, which is a sensed signal rectified by the MCU (B) 360. When the ceramic is completely contacted with the skin by the control of the MCU 100, When the body is abnormally contacted with the ceramic body or separated from the body, the electric power is reduced by the control of the MCU 100, and the electric current of a certain level or more is not applied to the human body.

The low frequency output unit 300 is driven in accordance with the set operation conditions such as the operation time, the low frequency intensity, and the low frequency mode even when the low frequency output mode is operated, and the low frequency mode operation is stopped when the input time elapses A high frequency output unit and a low frequency output unit can be selected individually or simultaneously to perform a function of a physical therapy device capable of selectively managing according to the state of the body.

At this time, if the high-frequency or low-frequency operation mode setting time elapses or the overcurrent is detected by the sensor, the high-frequency operation is stopped and the low-frequency operation is automatically performed. When the high-frequency heat is cooled after a certain time, the high-frequency operation is automatically and repeatedly performed.

In the present invention, the high-frequency output of the high-frequency output section is applied to the high-frequency output section by applying PWM-HI and PWM-LOW high-frequency signals (pulses) of pulse width modulation In particular, even if the power is supplied to the high-frequency output part during PWM-LOW operation, the input value becomes "0" to cut off the current to the therapeutic device, so that the therapeutic device can be safely separated from the body without any danger such as spark do.

As a result, the feedback control circuit configured to stabilize the output voltage as described above performs multiple safety functions.

The presence or absence of human body contact of the high frequency therapeutic electrode 260 and the low frequency therapeutic electrode 360 in the MCU 100 is determined according to the use sense resistor A and the use sense resistor B connected in series to the therapeutic electrode 260 and the low frequency therapeutic electrode 360 The output current is monitored in real time by feedback, and only high frequency and low frequency output are performed only when each therapeutic electrode is completely in contact with the skin. However, by controlling the amount of current to be outputted within a constant current value, The electrical stability can be improved by preventing an image or a shock caused by the spark,

Further, when the therapeutic porcelain 260 and the low-frequency therapeutic porcelain 360 are completely brought into contact with the skin under the control of the MCU 100, the power is stepped up to an appropriate energy required for the operation so as to output no side effect of the image due to the rapid temperature rise, When the human body is abnormally contacted with the therapeutic porcelain 260 and the low-frequency therapeutic porcelain 360 or separated from the human body, the control signal outputted from the abnormal operation under the control of the MCU 100 is supplied, The output is controlled by a stepwise reduction in power to a level that the human body is not overloaded so that there is no danger of the electric current, so that the output is controlled according to whether the therapeutic electrode is attached to the human body, Intelligent skin feedback system to prevent side effects such as shock, burn, and overheating Multiple safety device system It will be implemented.

In order to use it safely from the risk of burns, only when it comes into full contact with the human body, it operates by raising the output with the required energy. When the body is abnormally contacted or separated from the human body, the output is lowered, By providing multiple outputs with appropriate strength and power output in a range that does not adversely affect the human body by stopping the operation, the electric stability can be improved to increase the electrical moment of the patient due to the instantaneous current flowing into the congestion phenomenon. By performing multiple safety device functions that can provide various, appropriate, and safe stimulation of irregular, even heat, it is possible to achieve a pleasant output effect for each function.
