【Example】

 Hereinafter, two embodiments will be shown in the drawings and the ultrasonic beauty treatment apparatus according to the present invention will be described in more detail. FIG. 1 shows a probe 10 of an ultrasonic beauty treatment device according to the present invention and an external control device 20 attached thereto.

The main part of the probe 10 is composed of a cylindrical tubular body CS that can be held by one hand, a tip portion CP attached to the tip thereof, and a connection sealing portion CN ₀ . The tip portion CP has a high ultrasonic vibration transmission efficiency and is formed of a conductive light metal, preferably aluminum or an alloy thereof, and adheres to a desired portion of the body to be cosmetically treated on the outer surface. The piezoelectric element PEZ is bonded to the inner surface of the tip portion CP with an adhesive. The high frequency current applied to the piezoelectric element PEZ is supplied from the external control device 20 via the connection cable L ₀ and the conductors L _{c and} L _a . The cylindrical body CS is made of a synthetic resin, such as ABS resin, which reduces the weight of the probe in order to facilitate handling of the probe. The connection sealing portion CN ₀ is made of a relatively soft insulating material, for example, synthetic rubber or a resin block, and is equipped with a connector CNT that facilitates the assembly and disassembly of the probe and facilitates the connection of the electric wire from the control device 20. Has been done.

According to the present invention, another connection sealing portion CN ₁ is provided in a part of the cylindrical body CS, and another electric conducting wire L _b is fed from the inside of the probe 10 through this connection sealing portion CN _1. It is outside. A conductive clamp electrode EL is connected to the tip of the electric conducting wire L _b for conducting contact with the skin. In the case of this embodiment, the clamp electrode EL can be attached while being clamped to a part of the body of a person who is to be subjected to ultrasonic treatment, for example, an arm. The other end of the other electric conductor L _b is also connected to the external control device 20 in the probe 10 via the connector CNT and the connection cable L ₀ .

Further, according to the present invention, the tip portion CP of the light metal and the piezoelectric element PEZ are bonded by the thermoplastic adhesive. As is well known, the piezoelectric element has a thin disk shape, and metal electrode layers are deposited on the upper and lower surfaces of the piezoelectric element ceramic disk. The adhesive layer of the above-mentioned thermoplastic adhesive is extremely thin, and the ordinary adhesive treatment maintains sufficient conductivity. In other words, the conductive wire L _c is practically sufficient for electrical conduction between the tip portion CP and the electrode of the piezoelectric element PE Z that is in close contact with the tip portion via the adhesive layer. If the conductive property of this adhesive layer is not sufficient, it is possible to form a sufficiently conductive layer by dispersing fine silver particles in the adhesive.

The main part of the external control device 20 that supplies power to the probe 10 is shown in the circuit diagram of FIG. The high frequency sine wave signal generated by the oscillator circuit OCR in the control device 20 is supplied to the drive circuit DR ₁ and, after power amplification, is supplied to the electrodes A and B respectively connected to both surfaces of the piezoelectric element PEZ. . Then, high-frequency mechanical vibration is generated in the piezoelectric element PEZ by this oscillation power. The frequency of this oscillation is in the ultrasonic range, ie above 20 kHz, preferably between 1 and 3 MHz.

On the other hand, a low frequency oscillator MB for generating a low frequency electric oscillation signal, preferably a rectangular wave pulse electric signal, is also provided in the external control device 20. This pulsed electric signal has a frequency of several Hz to several tens of Hz. This low-frequency oscillator circuit MB can be constructed using, for example, a self-running multivibrator. The pulse duty ratio and frequency can be varied by properly selecting the time constant of this free-running multivibrator. The generated pulse electric signal is supplied to another drive circuit DR2, and after power amplification, the one end B of the piezoelectric element PEZ on the one hand and the clamp electrode EL on the other end via the current limiting resistance _RL . Supplied in between. In this case, the current limiting resistance R _L is for protecting the circuit when an excessive current (for example, a short circuit) occurs between the end B and the clamp electrode EL. The end B of the piezoelectric element PEZ is connected to the tip of the tip CP of the probe 10, and is grounded via the ground terminal G as shown in FIG. This low-frequency pulse voltage has a frequency of several Hz to several tens of Hz, and the level of the applied DC voltage is DC 150 V at maximum.

As shown in FIG. 3, the power supply of the control device generates an AC voltage stepped down from the commercial power supply AC 100 V by the transformer T, and the rectification stack D and the smoothing capacitors C _1, C are generated from this low AC voltage. _A DC voltage is formed by 2 and this DC voltage is stabilized by a voltage control element, for example, positive and negative three-terminal regulators RG _{1 and} RG _{2 ,} and a positive voltage V is applied to each active element (DR _1, DR ₂ etc.). Supply _CC (eg + 12V) and negative voltage V _EE (eg -12V). Further, the transformer T has another winding in order to generate a relatively high voltage for the DC pulse, and the voltage taken out between the other windings is smoothed by the rectification diode D ₀ and the capacitor C _0. , A constant voltage source V ₋ is obtained by another voltage control unit (in the case shown, constituted by a Zener diode ZD and a transistor Tr).

The ultrasonic waves and DC pulse voltage generated by the probe 10 are controlled by an operating means K including a switch and a timer or a setting dial (detailed member names and arrangements are omitted because they are well known in themselves). According to the control signals α, β _1, β _2, β _3, γ, δ supplied from the sequence control unit CTL, it can be appropriately selected and generated.

As shown in FIG. 2, the control signal supplied from the sequence control circuit is α: a signal for on / off and fine adjustment of the ultrasonic oscillator β ₁ : a signal for setting the peak value of the output pulse of the low frequency oscillator circuit β ₂ : Low frequency oscillator frequency variable signal β ₃ : Low frequency oscillator duty ratio variable signal γ: Piezoelectric element on / off switching signal δ: Low frequency oscillator on / off switching signal . In this case, the control signals γ and δ are applied to the electromagnetic relays RE _{1 and} RE _{2 ,} respectively, to control conduction / non-conduction of the corresponding contacts. That is, when the relay RE ₁ is on, the piezoelectric element PEZ is excited, and when the relay RE ₂ is on, a low frequency DC pulse voltage is applied between the tip of the probe 10 and the clamp electrode EL.

According to this invention, the use mode program-controlled by the sequence controller CTL can be selected by the designation by the operating means K. These usage modes include: Use mode I: Only generate ultrasonic vibration Use mode II: Generate only low frequency DC pulse voltage Use mode III: Simultaneously generate ultrasonic vibration and low frequency DC pulse voltage In addition to these use modes I, II, III, or Use mode I is adopted during the following period and use mode II is adopted during the next period. Alternatively, the operating means K and the sequence control unit CTL are provided with a function capable of being programmed so that the use mode I is adopted in a certain period and the use mode III is adopted in the next period. Of course, such periods can be set by a timer. Further, the display panel of the external control device 20 should be provided with an indicator for displaying which usage mode is used or the elapsed time of the specific usage mode.

FIG. 4 shows a probe 10 according to a second embodiment of the present invention. This probe 10 is different from the probe of FIG. 1 in that the clamp electrode EL of the first embodiment is incorporated in the tip of the probe 10. In other respects, the structure and function are the same as those of the probe 10 of the first embodiment shown in FIG. 1, and the description thereof will be omitted. The tip portion CP is screwed to each other via a screw thread provided on the outer periphery of the tip of the cylindrical body CS and a screw thread provided on the inner wall of the tightening cap RN made of an electrically insulating material. In this tightening cap RN, as shown in FIG. 4B, there are three counter electrodes EL provided on the outer periphery of the tightening cap RN at three-fold symmetrical intervals. When the tip end CP is applied to the skin of a person who performs cosmetic treatment, these electrodes EL can be brought into conductive contact with the skin site. The conducting wire L _b extending from the connector CNT in the probe 10 passes through the connecting terminal TN provided on the inner wall of the tubular body CS and the conducting wire embedded in the tubular body CS, and further the tip of the tubular body CS and the tightening cap RN. The electrodes EL are electrically connected to each other via the contact terminals that are in contact with each other (the contact terminals are not shown). The advantage of the probe 10 of the second embodiment is that the DC pulse voltage can be applied in a state where it is limited to the part where ultrasonic vibration is actually applied.

In order to use the ultrasonic beauty treatment device according to the present invention, first, the skin to be subjected to the beauty treatment is soaked in warm water or rubbed with a warm towel or the like to sufficiently soften the living tissue. Furthermore, if necessary, beauty treatment liquid or lotion is applied in advance. Next, the operating mode to be used is set by the operating means K of the external control device. For example, when the use mode I and the use mode II are combined, the ultrasonic treatment is performed after applying the DC pulse voltage to the skin for a predetermined period. Alternatively, in the use mode III, ultrasonic treatment and application of DC pulse voltage are simultaneously performed. In these cases, the probe is brought into close contact with the skin to be treated and slid around it to perform ultrasonic cosmetic treatment. Such a combined beauty treatment works much more effectively than when each beauty treatment is performed individually.

In the first embodiment, the counter electrode for applying the DC pulse voltage has been described as a clamp member or a scissors-shaped member. However, other configurations are possible. For example, a suction cup that can make conductive contact with the skin or a belt that can be wound and tightened is also conceivable. Further, the lead wire to the counter electrode can be directly led not by the probe cylinder but by an external control device.

In addition, various modifications and alterations are possible. However, all the devices having the configurations defined in the claims for utility model registration belong to the ultrasonic beauty treatment device of the present invention.
