Similarly, the other potential is applied to the counter electrode rod 40 which is crimped onto a desired part of the skin at a predetermined distance from the electrode rod 30 via the conductor LX from the connection terminal C2 of the power supply main body 20 to the electrode tip 42. supplied to

The difference between this counter electrode rod 40 and the electrode rod 30 is that the former is further equipped with a function of transmitting ultrasonic vibrations to the electrode tip 42.

That is, an excitation voltage is supplied from the connection terminal C3 of the power supply main body 20 to the ultrasonic wave generating element 44 of the counter electrode bar 40 via the conductor L3. This ultrasonic generating element 44, electrode tip 42
The ultrasonic mechanical vibrations emitted from this element are directly transmitted to the electrode tip 42 and finally introduced into the skin.

The surface of this counter electrode 40 is also constituted by an insulating cover 41 made of an electrically insulated synthetic resin material. The ultrasonic generating element 44 is a piezoelectric element, and the main body is an insulator, so
The potential of the conductor L2 is transferred to the conductor 43 which detours inside the insulating cover 41.
It communicates with the electrode tip 42 via. Note that, in order to efficiently transmit ultrasonic waves, the electrode tip 42 is advantageously made of a lightweight material, such as aluminum or its alloy, or ceramics whose surface is conductively treated (metalized) (for example, alumina).

Although the tip 32 of the electrode rod 30 and the tip 42 of the counter electrode 40 are implicitly shown to have a round shape in FIG. It may also have an elliptical or rectangular contact cross section.

The main components of the power supply main body 20 include an operation/display section 21, a power input section 22, an applied voltage source 23, a power distribution section 24, and an oscillation power source 25.

The power input section 22 receives commercial power supplied to the power supply main body 20, and the power distribution section 24 supplies this power to the operation/display section 21, the applied voltage source 23, and the oscillation source 2.
Each part 2 is converted to the specified DC or AC power supply required for 5.
Provided on 1.23.25. For the applied voltage a23, a DC voltage or an AC voltage (mainly a pulsed DC voltage) is applied between the electrode rod 30 and the counter electrode 40 (Jt). In that case, the operation/display unit 21 The polarity of the applied voltage or the cycle of the AC voltage supplied from the applied voltage source 23 can be changed according to a command input to the oscillating power source 25. The oscillating power source 25 generates an excitation voltage to be supplied to the ultrasonic generating element 44 of the counter electrode bar 40. And the frequency is 1 to 3
It's Mllz. In addition to inverting the polarity and changing the period of the voltage applied to the electrode rods 30 and 40 described above, the operation/display unit 21 also controls a timer for setting the applied voltage and the period of generation of ultrasonic waves, and the value of the applied voltage and ultrasonic wave. It has a switch or variable resistor to set the value of the sound wave output, and an analog or digital display meter to display the value.

The actual circuit configurations of the applied voltage tA23 and the oscillation type tA25 are disclosed in other patent applications (Japanese Patent Application No. 1262240, respectively).
