2. Description of the Related Art As an apparatus for performing an ultrasonic cosmetic treatment, the present applicant has already proposed an ultrasonic cosmetic treatment apparatus using an ultrasonic vibrator made of a ferroelectric substance in Japanese Patent Application Laid-Open No. 3-123559. This ultrasonic vibration mainly applies high-frequency mechanical vibration of around 1 MHz to the body, for example, the surface of the face,
The beauty treatment is performed intensively on the site. This vibration transmits mechanical vibration generated from the vibrator to the skin via a thin vibration transmission plate.

Further, the present applicant has filed utility model registration number 30.
Japanese Patent Publication No. 31511 (Japanese Utility Model Application No. 8-1689) also proposes a complex beauty treatment apparatus having an ultrasonic wave application function and a heating / heating function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on preferred embodiments with reference to the drawings. 1 and 2
FIG. 1 shows an exemplary device configuration in which the method according to the invention can be implemented. The ultrasonic probe 40 is the same as disclosed in
Since the resonance frequency of the vibrator is about 1 MHz, the application area is almost circular and the diameter is about 4 MHz.
Details other than 0 mm are not described here. To excite the ultrasonic vibrator, oscillation by a so-called inverter circuit is used. That is, the main oscillation output section 32 in the apparatus main body 10 is driven by the drive circuit 36 that drives the coils of the pulse transformer T, the transistors Tr ₁ and Tr _2, and the bases of both transistors, which receive the DC output power of the DC power supply 35 in a center tap manner. It is configured. The output of the secondary winding of the transformer T is supplied to the probe 40 having a built-in ultrasonic vibrator through the conductive wire L _5.

The DC power supply 35 is configured to vary its DC output voltage in order to vary the power intensity supplied to the ultrasonic probe 40. Generally, when the DC voltage applied to the inverter circuit changes, the oscillation frequency also changes. However, the ultrasonic vibrator is excited only at a constant frequency (oscillation frequency). as variable and even if the oscillation frequency does not change, drives the output of the secondary winding through the detection wire L ₄ 36
And the excitation of the transistors Tr ₁ and Tr ₂ is varied.

The apparatus main body 10 has another function of varying the DC output of the DC power supply 35 in order to vary the ultrasonic output of the probe 40. This function is realized by the arithmetic processing unit 30 to send the DC power supply 35 a control signal via conductor L _2. As shown in FIG. 1, the arithmetic processing unit 30
A large-scale integrated circuit (for example, in which an OM storage unit, a RAM storage unit, an interface, a microprocessor, and a management unit including these circuit elements are all integrated in one chip)
HD 6413378 F 10). The arithmetic processing unit 30 is controlled by the operation signal supplied via conductors L ₁ from the operation and display unit 25 to be described later in detail based on FIGS. 2 and 3.

FIG. 2 shows an operation / display unit 25 of the apparatus main body 10.
The details are shown below. The power of the entire main body can be turned on / off by the operation switch 12, and the state can be displayed by the light emitting diode 14. With the push button type elliptical mode changeover switch 16, the mode of "continuous", "intermittent", "variable 1" and "variable 2" can be selected on the corresponding display section 18. Each time the mode switch 16 is pressed, the above four modes can be sequentially switched. The “continuous” mode is a mode in which a constant output ultrasonic vibration is output continuously. , Are output again for a certain period of time. “Variable 1” corresponds to the pine surge mode, and “variable 2” corresponds to the fat burning mode. This will be further described with reference to FIG. Further, the ultrasonic intensity can be varied among “face”, “body 1”, and “body 2” on the corresponding display unit 22 by the intensity changeover switch 20. The circles on the left of the display unit 18 and the display unit 22 are light emitting diodes indicating the selected state, and the rectangle on the right indicates a display character in which the corresponding mode or intensity is written. The portion indicated by the reference numeral 24 is a mode display or a numerical value display portion indicating the period.

FIG. 3A shows an output voltage waveform in the "variable 1" pine surge mode, and FIG. 3B shows an output voltage waveform in the "variable 2" fat burning mode. “Variable 1” in FIG. 3A
In the pine surge mode changes continuously at the maximum output P _M following values output P is inherent in the probe, the maximum value P
Between the _H and the minimum value P _L is repeatedly varying substantially sinusoidal. In this case, the minimum value P _L is set to a value larger than zero (corresponding to stopping excitation of the vibrating element or stopping energization of this element), and its period is t ₀ .

In the “variable 2” fat burning mode of FIG. 3B, the output P is varied in three stages, and the maximum output P _{1, the} intermediate output P _2,
Certain period t ₁ is the minimum output P _{3 respectively,} t _2, t ₃ are maintained. In this case, the maximum output P ₁ is set below the maximum output P _M, the minimum output P ₃ is greater than zero. In this embodiment, the period t ₀ is 4 to 10 in the pine surge mode.
A value between seconds is selected and the output P _L ~
P _H is 0.1 to 0.3, respectively, 0.4-0.8, is 0.1 ~ 0.8 W / cm ² is selected for the "face", "body 1", "body 2". In the fat burning mode, the periods t1 _, t2 _, t
₃ selects any value from 10 to 30 seconds, and outputs P ₁ , P ₂ , and P ₃ are set to 0.2, respectively for “face”, “body 1”, and “body 2” for intensity setting. 0.3, 0.4;
0.5, 0.7, 0.8; 0.3, 0.5, 0.8 W / cm ² are selected.

In the case of this embodiment, the outputtable ultrasonic output (in terms of electric power) can be varied between a minimum value of 0.1 and a maximum value of 0.8 W / cm ^2. It has been chosen to be smaller. Arithmetic processing unit 3
0 is set in response to an operation switch signal from the mode switch 16 and the intensity switch 20 of the operation / display unit 25.
A corresponding control signal is sent to the DC power supply 35 to generate a DC voltage having an appropriate output period and an appropriate output intensity. In this case, the arithmetic processing unit 30 reads out a predetermined arithmetic processing stored in the ROM storage, generates the corresponding control signal using the RAM storage, and converts the digital processing signal into an analog signal through an interface. It is converted into a component and supplied to the DC power supply 35.

The numerical values in the above examples are shown for reference only, and the method of the present invention is not limited to these numerical values. In addition, the pine surge mode (Fig. 3
In A), the output waveform is described as a substantially sinusoidal wave, but other continuously changing waveforms can be used. The transition to each step output in the fat burning mode (FIG. 3B) is seen with a bluff. It may rise or fall with an inclination other than vertical. Also, the description has been given of the probe having the ultrasonic wave generating vibrator. However, it has another complex function, a heater including a heating element (for example, a type shown in Utility Model Registration No. 3031511), or another beauty treatment function. , A DC voltage pulse, high-frequency power, infrared light, ultraviolet light, or the like. In that case, the corresponding control power supply must also be included in the apparatus main body 10.

[0016]

According to the configuration of the ultrasonic cosmetic treatment apparatus according to the present invention described above, in addition to the well-known mode of continuously or intermittently outputting ultrasonic vibrations, at least two ultrasonic vibrations having different output intensities are provided. There is a mode that can be applied periodically by sequentially changing the intensity. The one with a relatively strong intensity and a long application period can be used to convert fine biological tissues of the body part at the molecular level (that is, for large tissues such as muscles, blood cells, lymph,
Or means organs that emit or generate them) Strong and high frequency shaking, used as a fat burning mode to burn fat, where the intensity is relatively weak and near the skin of the body if it changes continuously and periodically Is used as a pine surge mode that activates the living tissue to enhance metabolism and accordingly enhance the beauty treatment effect.

A particularly advantageous effect of the cosmetic treatment method of the present invention is that the rhythm inherent in a living body or a living tissue,
The point is that ultrasonic vibration is applied at a constant rhythm suitable for the biorhythm. The rhythm is not constant, but the intensity and the application period are changed quasi-periodically, and has an effect different from continuous or intermittent on / off ultrasonic application.

Changing the intensity also changes the depth at which the ultrasonic vibration penetrates into the body, in particular, the living tissue near the skin. That is, the higher the intensity, the deeper the depth, and the lower the intensity, the lower the depth. This also means that the depth of a living tissue that can be subjected to cosmetic treatment by ultrasonic vibration can be varied. Furthermore, in the case of an ultrasonic probe using a ferroelectric vibrating element, if a high output is generated continuously, the amount of heat generated from the vibrating element itself is large, and an ultrasonic wave is continuously generated at a high output or the highest output. If so, there is a possibility that burns or inflammation may occur when the ultrasonic probe is gripped or the skin is applied to the tip. It is worth noting that such heat generation problems can also be brilliantly avoided or significantly suppressed with the device according to the invention.
