Reference numeral 216 denotes a power supply unit 216 for generating power of a size to be supplied to the power switching unit 217, and reference numeral 215 denotes a central signal processing unit for processing and controlling various signals of the low frequency generator.

The signal output unit 230, by using a low frequency generated from the low frequency generating unit 210 to stimulate the skin of the human body by a plurality of output projections (not shown) made of a material harmless to the human body Is done.

The mode display unit 240 is selected by the user to operate by combining a plurality of output protrusions of the signal output unit 230. In order to display such a combination state, the number of LEDs of the output protrusions is used. In this case, the LED corresponding to the output protrusion at which the low frequency is output emits light and displays the same.

The LCD display unit 250 is configured to display the state of the overall system such as displaying various functions such as the output state of the signal output unit 230 and the remaining battery capacity.

The intensity control unit 260, by adjusting the strength of the output of the signal output unit 230, an up button (not shown) to increase the intensity of the output, and a down button (shown to reduce the intensity of the output) Not used).

The power switch 217 is disposed on both sides of the strength control unit 260 to open and close the power.

The mode selection unit 280 is adjusted to operate by combining the output projections of the signal output unit 230, and is configured to allow multi-level selection.

The conventional low frequency treatment device configured as described above is operated as follows.

In a state where power is supplied from the power supply unit 216, the power switch 217 is turned on to output the supply power of the power supply unit 216. When power is input, the central signal processor 215 operates the pulse generator 212, and the pulse generator 212 generates an operation pulse based on the oscillation output of the oscillator 211. The signal generated by the pulse generator 212 is to boost the voltage in the voltage converter 213, the signal is output to the signal output unit 230 through the mode control unit 214.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the low-frequency treatment device synchronized with the skin resistance value and heart rate according to the present invention.

The low-frequency therapy device synchronized with the skin resistance value and heart rate of the present invention is configured to generate a pulse having a frequency synchronized with the heartbeat of the subject. In addition, the low frequency treatment device synchronized with the skin resistance value and heart rate of the present invention measures the skin resistance value of the subject and adjusts the output intensity of the low frequency signal output to the subject in accordance with the measured skin resistance value. Therefore, prior to the description of the low frequency treatment device synchronized with the skin resistance value and heart rate of the present invention, the process of measuring the skin resistance value of the examinee will be described first.

2 and 3 is a configuration of the skin resistance measuring device used in the low-frequency therapy device synchronized with the skin resistance value and heart rate of the present invention.

The skin resistance measuring apparatus includes a plurality of measuring probes (3, 5 ...). The plurality of measuring probes 3, 5... Remain in contact with each other on the human skin of the examinee 1. If the device is provided with 24 measurement probes, the test subject 1 performs skin resistance measurement with all 24 measurement probes attached to the human body. The number of the measurement probes varies depending on the device specification and the application.

The skin resistance measuring apparatus includes one reference probe 7. The reference probe 7 is attached to the position of the examinee 1 which provides a reference point for measuring skin resistance. The skin resistance measuring device having such a configuration has a skin resistance between the reference probe 7 and each measuring probe (3,5 ...) (skin resistance between 7-3, skin resistance between 7-5, .. ...).

The plurality of measuring probes 3, 5... Are connected to a current measuring unit 9 for detecting a minute current of each measuring probe. The current value applied to the skin resistance measuring device is a very fine value (200 µA). The current measuring section 9 can also be configured to include an amplifying section for amplifying the detected value. The current measuring unit 9 may also include a configuration for removing a noisy signal. In the present invention, the current measuring unit 9 uses a current / voltage conversion element.

Since the current measuring unit 9 must be configured to detect current for each measuring probe 3, 5..., The detection elements 11, 13 are attached to each measuring probe 3, 5. Each consists of a connection. The detection elements 11 and 13 may use op amps that are differentially amplified. Although not shown, the detection elements 11 and 13 are provided with operating power (+12 V and -12 V) at all times, and power is supplied to the measurement pro- duct connected to the detection element. At the time, it is operated to detect the desired skin resistance value.

The operation of the current measuring unit 9 is controlled by the power supply module 15. The power supply module 15 is a measurement probe that is desired to operate among a plurality of measurement probes 3, 5 ... Only configured to supply voltage and current selectively. For example, when measuring skin resistance between the measurement probe 3 and the reference probe 7, a current value desired to be detected through the detection element 11 is detected while power is supplied to the measurement probe 3. The voltage supplied to the measurement probe is about 12 volts and the current is about 200 μA maximum.

The current measuring section 9 is connected to an analog / digital converter 17. The analog-to-digital converter 17 converts the detected current (voltage value corresponding to the current) into a digital signal and transfers it to the computer 25 side.

The computer 25 performs predetermined calculation processing on the measured value through the calculation / control unit 29 at the request of the inspector. At this time, the operation control is performed by applying a predetermined arbitrary value. The random value is a value preset by the examiner according to the test function of the examinee, and is stored in the memory 27. Further, the computer 25 can supply the measured value to the display unit 23 or transmit the measured value to an external device through the communication unit 31 or the like under the control of the operation / control unit 29. The computer 25 is also responsible for selecting a measurement probe for detection. That is, the inspector selects a measurement probe to be operated through the computer 25, and a signal corresponding to the selected measurement probe is output to the outside of the computer 25.

In other words, the computer 25 is configured to perform arithmetic processing, display control, and output a tester input signal. Therefore, the computer 25 includes all of the general computer configurations (input devices, .....) although not shown in the drawings. In addition, the computer 25 should be provided with a control program connected to the skin resistance measuring device to perform the control. The control program is stored in the memory 27.

The signal corresponding to the measurement probe selected by the computer 25 is applied to the measurement probe selection control circuit 19 through the digital / analog converter 21. The digital / analog converter 21 performs a function of converting the output signal of the computer 25 into a signal recognizable by the measurement probe selection control circuit 19.

The measurement probe selection control circuit 19 controls the operation of the voltage supply module 15. That is, a selection signal is output so that power is supplied only to the measurement probe to be operated through the voltage supply module 15.

3 is an exemplary diagram for explaining a basic operating principle for measuring skin resistance between the measurement probes 3, 5... And the reference probe 7 in the skin resistance measuring apparatus. .

That is, as shown, a plurality of measurement probes 3, 5... Are provided. Each of the measuring probes 3, 5 ... is connected with a detection element 11, 13, which detects a minute current flowing between the measuring probe and the reference probe.

The measuring probes (3, 5, ...) are configured to be supplied with a constant voltage (about 12 volts) and a maximum current (200 µA). That is, as shown, one side of the resistor R1 is connected to the power supply 12, and the other side of the resistor R1 is connected to the resistor R2 and the first input terminal of the detection element 11. Connected. One side of the resistor R2 is connected to the second input terminal of the detection element 11 and one side of the variable resistor VR1, and the other side of the variable resistor VR1 is connected to the measurement probe 3. Connected. The reference probe 7 is connected to the power supply 12 through a resistor R5.

A switch SW1 is connected between the power supply 12 and the resistor R1, and a switch SW2 is connected between the power supply 12 and the resistor R3. The two switches SW1 and SW2 play a role of opening and closing the supply of power to the measurement probes 3 and 5...

The detection element 13 also has the above configuration. That is, one side of the resistor R3 is connected to the power supply 12, and the other side of the resistor R3 is connected to the resistor R4 and the first input terminal of the detection element 13. One side of the resistor R4 is connected to the second input terminal of the detection element 13 and one side of the variable resistor VR2, and the other side of the variable resistor VR2 is connected to the measurement probe 5. Connected. In addition to this, the detection element is provided as many as the number of measurement probes provided.

Therefore, the measurement of the skin resistance is made by first attaching all the measurement probes (3, 5, ...) to the human body of the examinee. At this time, it is important to attach all measuring probes (3, 5, ...) to the human body regardless of operation.

Select the measurement probe to be operated next. Apply power to the corresponding measurement probe, and do not apply power to the measurement probe that is not applicable. The operation is achieved by controlling the switches SW1, SW2 ... connected to the measurement probe in the on state.

Through the above operation, the detection element connected to the measurement probe to be operated is in a state capable of measuring skin resistance. For example, when the switch SW1 is controlled to the on state, when the power is applied to the measuring probe 3 and the power is not applied to the other measuring probe 5, only the detection element 11 measures skin resistance. It becomes possible state.

In this state, when a current is supplied from the power supply 12, the current flows between the measuring probe 3 and the reference probe 7 in the operating state. At this time, the detection element 11 detects and outputs the current value which flows (at this time, a signal is detected with the voltage value corresponding to a current value which flows). The signal is amplified by a predetermined output. At this time, since no power is supplied to the measurement probe 5, the detection element 13 cannot detect skin resistance.

The following describes the overall operating process of the skin resistance measuring apparatus that is operated on the same principle as described above.

The examiner attaches all of the plurality of measurement probes 3, 5,... Provided in the skin resistance measuring apparatus to the test position on the human body of the test subject 1. The plurality of measuring probes 3, 5, ... are all attached to the human body of the examinee 1 regardless of their operation. The reference probe 7 is also attached to a specific body part of the subject 1.

Next, the inspector performs an operation of selecting the measurement probes 3, 5, ... to be measured through the computer 25 connected to the skin resistance measuring device or the display / measurement / input device.

To this end, the computer 25 reads and operates a program related to the skin resistance measurement value stored in the memory 27. In the program, an inspection item and an inspection method are selected.

The inspector sets the values according to the selected method and the inspected object. Then, a predetermined value to be given to the inspection value of the inspection subject will be set according to the inspection criteria of the inspector. The set value is applied later in the calculation process. The set value may be set differently or identically for each examinee according to an examiner's judgment standard.

Next, the inspector selects a measurement probe to be measured according to the selected inspection item and inspection method. For example, in a serial method, one measurement probe will be operated sequentially, and in a parallel method, all measurement probes will be controlled to operate simultaneously.

The computer 25 outputs a measurement probe selection signal so that the selected measurement probe can be operated. The output measurement probe selection signal is a digital signal. Accordingly, the digital signal is converted into an analog signal so that the digital-to-analog converter 21 can recognize the skin resistance measuring device.

The converted analog measurement probe selection signal is input to the measurement probe selection control circuit 19. The measurement probe selection control circuit 19 controls the power supply module 15 to supply power only to the measurement probe to be operated based on the input signal. The power supply module 15 controls the measurement. Under the control of the probe selection control circuit 19, power is supplied only to the measurement probe to be operated.

The current flows between the measurement point (measurement probe) and the reference point (reference probe) to be measured by the control, and the current measuring unit 9 detects skin resistance. The skin resistance detected by the current measuring unit 9 is output after being amplified by a predetermined amount in the current measuring unit 9.

The output detection signal is converted into a digital signal by the analog / digital converter 17 and input to the computer 25. The detection signal input to the computer 25 is calculated together with the set value. The calculation indicates signal processing corresponding to processing required by the inspector. For example, a process of converting the measured value into a display control signal may be included. In addition, the step of converting the voltage corresponding to the current detected by the current measuring unit 9 to a current value, and converts it back to the skin resistance (R) and the like.

The detection signal calculated through this process is displayed and controlled on the display unit 23 under the control of the operation / control unit 29, and is also selectively stored in a predetermined area of the memory 27.

The skin resistance value computed and detected by the computer 25 is provided to the central signal processor 115 of the low frequency treatment apparatus described later through the communication unit 31.

Next will be described in detail with respect to the low-frequency treatment device synchronized with the skin resistance value and heart rate according to the present invention.

2 is a control block diagram of a low-frequency treatment device synchronized with the skin resistance value and heart rate according to the present invention.

The low frequency treatment device synchronized with the skin resistance value and heart rate of the present invention is configured to generate a pulse based on the heartbeat of the subject. That is, as shown, the low-frequency treatment device of the present invention includes a heart rate sensor 111. The heart rate sensor 111 is attached to the human body of the examinee and used for heart rate measurement.

The output of the heart rate sensor 111 is provided to the pulse generator 112. The pulse generator 112 generates a pulse signal having a frequency of a predetermined size based on the heart rate measured by the heart rate sensor 111. In this case, the frequency of the pulse signal generated by the pulse generator 112 is a frequency of a predetermined size by adding or subtracting a constant of a predetermined value to the heart rate detected by the heart rate sensor 111. The said constant is set to the value based on an experimental value. The pulse generator 112 is configured to be controlled by the central signal processor 115 to be described later.

The pulse signal having a frequency of a predetermined magnitude generated by the pulse generator 112 is output to the voltage converter 113. The voltage converter 113 boosts the applied pulse signal by a predetermined amount and outputs the pulse signal to the mode controller 114.

The mode adjusting unit 114 is configured to adjust the waveform of the pulse signal output from the signal output unit 130. The mode adjusting unit 114 is operated in association with the mode selecting unit 180. That is, assuming that the mode selectable by the mode selector 180 is divided into a square wave, a sine wave, a triangular wave, a mixed wave, and the like, the user selects a desired pulse waveform mode from the mode selector 180. The mode controller 114 outputs the pulse waveform signal selected by the mode selector 180. The mode adjusting unit 114 is configured to be controlled by the central signal processing unit 115 to be described later.

In addition, the low frequency treatment apparatus synchronized with the skin resistance value and heart rate of the present invention includes a skin resistance measuring device 160 for measuring skin resistance of the subject. The skin resistance measuring device 160 measures the skin resistance value flowing through the human body of the examinee.

The skin resistance measured by the skin resistance measuring apparatus 160 is applied to the central signal processor 115. The central signal processor 115 determines the output intensity of the pulse signal output from the signal output unit 130 based on the skin resistance value measured by the skin resistance measurement device 160. For example, when the skin resistance is high, the supply voltage is increased. On the contrary, when the skin resistance is low, a relatively low voltage is supplied. That is, the average value of the current flowing through all the power probes attached to the human body is constantly adjusted by controlling the voltage of the power supplied to the corresponding position in synchronization with the skin resistance of each part of the human body. Of course, the magnitude of the current to be supplied to the human body is limited, and its maximum value is set.

The central signal processor 115 plays a role of a controller for controlling the overall flow of the low frequency treatment device. Therefore, various data necessary for the operation of the low frequency treatment device are stored. In particular, the mode control unit based on the control data for the pulse waveform to be output to the pulse generator 112 according to the mode signal selected by the mode selector 180, the skin resistance value measured by the skin resistance measurement device 160. The control data for adjusting the output intensity of the pulse signal to be output to the 114, the display control data to be displayed on the LCD display unit 150, and the like. The central signal processor 115 is configured to transmit and receive various signals. Therefore, it is preferable that the central signal processing unit 115 use a normal computer.

The other mode display unit 140 displays the currently selected mode, and the power supply unit 116 and the power switch 117 control the power supply and the power supply opening and closing of the low frequency treatment device. In addition, the LCD display unit 150 displays various operating states of the current low frequency treatment device.

Next will be described the operation of the low-frequency treatment device synchronized with the skin resistance value and heart rate according to the present invention made up of the above configuration.

One of the characteristics of the low frequency treatment device synchronized with the skin resistance value and the heartbeat according to the present invention is to control the frequency of the pulse signal according to the heartbeat of the blood test. The heartbeat of a person varies depending on the person's health and constitution. Nevertheless, the conventional low frequency treatment device constantly controls the frequency of the low frequency signal. Therefore, in the present invention, the control is performed so that a frequency that changes for each individual to be inspected can be set. To this end, in the present invention, the heart rate sensor 110 is provided.

When the power switch 117 is in the ON state and the power supplied through the power supply unit 116 is provided to the low frequency treatment unit, the low frequency treatment unit has an operating state under the control of the central signal processing unit 115.

The user selects a pulse waveform to be output through the mode selector 180. Depending on the product, the output waveform can be adjusted in various ways, but it includes triangular wave, square wave, sine wave, and mixed wave. The mode selected by the mode selector 180 is input to the central signal processor 115, and the central signal processor 115 controls the output waveform of the mode controller 114 in a state in which the selected mode is recognized.

The heart rate sensor 110 detects the heart rate of the subject. The detected heart rate is output to the pulse generator 112. The pulse generator 111 generates a reference pulse signal having a different frequency according to each subject by adding or subtracting a predetermined constant (preset value) to the heart rate detected by the heart rate sensor 110.

The reference pulse signal generated by the pulse generator 111 is input to the voltage converter 113. The voltage converter 113 boosts and outputs an output voltage of an input reference pulse signal. The pulse signal boosted by the voltage converter 113 is input to the mode controller 114.

The mode adjusting unit 114 is configured to be controlled by the central signal processing unit 115. The central signal processor 115 outputs the control signal according to the mode selection signal selected by the user and the intensity control value according to the skin resistance measured by the skin resistance measuring device 160 to the mode adjusting unit 114.

The skin resistance measuring device 160 measures the skin resistance value of a predetermined portion of the subject by the examiner. The measured skin resistance is provided to the central signal processor 115.

The central signal processor 115 adjusts the magnitude of the voltage to be supplied based on the measured skin resistance value. At this time, the voltage is adjusted so that the human body current flowing through the subject becomes an average value. That is, when the skin resistance value is larger than the reference value, the voltage value is increased. When the skin resistance value is smaller than the reference value, the voltage value is lowered. Therefore, the output intensity is adjusted to maintain the average of the human body current of the subject.

Therefore, the pulse signal output from the mode controller 114 is output in the form of a pulse waveform selected by the user through the mode selector 180. And it is output to the output intensity adjusted based on the skin resistance value measured by the skin resistance measurement device 160.

In this way, the low frequency signal output from the mode adjusting unit 114 is provided to the examinee through the signal output unit 130.

When the above operation is controlled, the LCD display unit 150 displays the operation state of the low frequency treatment unit and the like under the control of the central signal processing unit 115.

As described above, the low frequency treatment apparatus synchronized with the skin resistance value and the heartbeat according to the present invention is characterized by controlling the output intensity of the low frequency signal output in accordance with the skin resistance value of the treatment part of the examinee. In addition, the low-frequency therapy device synchronized with the skin resistance value and heart rate according to the present invention is characterized by controlling the output frequency based on the heart rate of the subject.

To this end, the low-frequency therapy device synchronized with the skin resistance value and heart rate of the present invention includes a heart rate sensor and adjusts the frequency based on the heart rate detected through the heart rate sensor. In addition, the low frequency treatment apparatus synchronized with the skin resistance value and heart rate of the present invention includes a skin resistance measuring device, and adjusts the output intensity of the low frequency signal based on the skin resistance value detected through the skin resistance measuring device. Through such control, the low frequency therapy apparatus synchronized with the skin resistance value and heart rate of the present invention can perform low frequency treatment synchronized with the heart rate and coincident with the skin resistance value.
