AC60V is held, AC15V exports direct current 21V after the first current rectifying and wave filtering circuit rectification, and supplies+5V ,+15V, -15V voltage.
AC60V exports direct current 90V through the second current rectifying and wave filtering circuit, and powers for DC/DC inversion units.The power supply of the present invention is all made of system
One power input, then through circuit conversion be different amplitudes, each unit, module for power supply for the present invention are only without setting
Vertical power supply so that power supply unit of the invention is simple in structure.
The use process and principle of the present invention is as follows：After powering on, by capacitive therapeutic electrode 1 and neutral plate electrode
3 are in contact with user's body, then capacitive treatment is opened；By resistance mode therapeutic electrode 2 and 3 user of neutral plate electrode
Body is in contact, then resistance mode treatment is opened.
The output end of second current rectifying and wave filtering circuit of the power input connection power supply unit in DC/DC inversion units, i.e.,
The power supply of DC/DC inversion units is the direct current that amplitude is 90V.Central control unit is inverse by the first output end control DC/DC
Become unit and voltage conversion is carried out to direct current 90V, DC/DC inversion units output amplitude is continuously adjusted direct current into 0V to 90V after converting
Voltage, user is according to the demand of itself, and by operating display unit, operation central control unit is to select, change direct current
The size of voltage.
Central control unit controls power amplification unit by second output terminal, by the direct-flow input end of power amplification unit
The direct current of input is converted to the AC signal of frequency 450KHz.
As shown in Fig. 2, capacitive therapeutic electrode 1 is capacitance cathode, neutral plate electrode 3 is capacitance cathode, is located at capacitance
Tissue between mode treatment electrode 1 and neutral plate electrode 3, then be taken as a part in capacitance.Tissue conduct
Medium is placed in the capacitance field between two electrodes of capacitance, because tissue has the duality of electrolyte and conductor concurrently, therefore
Under the action of high-frequency electric field, tissue non-polar molecule polarization, polar molecule is orientated.Due to 1 quilt of capacitive therapeutic electrode
Apply the AC signal signal of frequency 450KHz, therefore the electric field of capacitance changes repeatedly, therefore dipole occurs and high-frequency electrical
The corresponding high speed of field frequencies range is orientated repeatedly, and makees 180 ° of rotation repeatedly, and Charge sites movement built in dipole generates displacement
The size of electric current, the electric current is codetermined by the impedance of voltage and tissue between capacitive field the two poles of the earth.And by the present invention
Principle it is found that voltage between capacitive field the two poles of the earth, is the amplitude by the AC signal of the output of power amplification unit and resistance
What the impedance of anti-match circuit determined.Therefore, displacement current is by the impedance of tissue, the amplitude of AC signal and impedance matching
The impedance of circuit determines.
For the effect of the health and treatment of tissue, which is typically sized to 0mA-500mA.
Friction and the friction between medium around each other occur for dipole high speed rotation, and overcome dielectric
Resistance, caused energy loss are converted to thermal energy, i.e., generate thermal energy in human body；Also there is high speed and moves in people's cylinder electrolyte ion
Dynamic, generating conduction electric current and ohmic loss makes to heat up in electric field inner tissue.In addition, electromagnetic field of high frequency human body also will produce it is non-
Fuel factor, non-thermal effect refer to before making body that temperature change occur, and have occurred and that mobile ion, dipole and colloid grains in vivo
Biophysics, biochemistry, the metabolism such as son rotation, film potential variation, membrane permeability variation, the protein ingredient moulding of cell change
Varying effect.Capacitance treatment mode mainly acts on human body soft tissue, such as muscle, blood vessel, extracellular environment, intracellular loops
Border, dermal tissue, lymph.
As shown in figure 3, resistance treatment mode applies tissue by resistance mode therapeutic electrode 2 and neutral plate electrode 3
Add a frequency be 450Khz sine wave continuous current, in order to tissue health and treatment effect, electric current it is big
Small is 0mA-1000mA, and the size of the voltage at tissue both ends is 0V-100V.Similar with capacitance treatment mode, sine wave connects
Continuous electric current is determined by the impedance of tissue, the impedance of the amplitude of AC signal and impedance matching circuit.Resistance treatment mode is
Using the resistance characteristic of human body, the channel of an electric current is established in human body, and the movement of inside of human body ion is concentrated in
Positive and negative electrode m- therefore we are able to be deep into human body deep layer, therefore, this pattern mainly act on human body internal resistance value compared with
High tissue, bone, tendon, ligament, cartilage, microscopic structure, therefore, resistance mode may act on human body deep, while thermal effect
It should be apparent.
In capacitance treatment mode, the load impedance that tissue is constituted is a motional impedance, so output circuit
Impedance be also a motional impedance.The actual value and calculated value of output voltage are at certain functional relation, if some time
It is unsatisfactory for this relationship quarter, illustrates that output circuit impedance is mismatched with load impedance, circuit job insecurity can be caused in this way, very
To meeting damaged circuit.The setting of Current Voltage collecting unit, for acquiring capacitive therapeutic electrode 1 and resistance mode treatment electricity
The electric current of the electric current of 2 output end of pole, the acquisition of Current Voltage collecting unit feeds back to central control unit after treatment, center
Whether the impedance of control unit decision circuitry matches with load impedance, and the parameter for adjusting impedance matching circuit makes output circuit impedance
It is matched with load impedance, circuit is made to be operated in stable state.
Therefore, it is necessary to by central processing unit, the rational impedance magnitude for controlling impedance matching circuit.When tissue
When impedance changes, the impedance magnitude and tissue matches impedances of impedance matching circuit are adjusted, is ensured in tissue
Sine wave continuous current and displacement current size reasonable.
The present invention modulates high frequency by DC/DC inversion units and power amplification unit（450KHz）, long wave（600m）, etc.
The sine wave of width concussion, the distinctive electromagnetic frequencies of 450Khz generate biological effect and fuel factor, act on corresponding machine to targeting
Body tissue, while to environment electromagnetic-radiation-free；Two kinds for the treatment of modes of capacitance treatment mode and resistance treatment mode are set, are suitable for
