DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
[0014]
(1) Configuration of Embodiment FIG. 1 is a block diagram showing a beauty tool according to an embodiment of the present invention. In this beauty tool 1, a drive unit 3 and an electric field forming unit 4 are housed in a main body 2, and a probe 5 is movably connected to the main body 2 via a cable.
[0015]
Here, as shown in FIG. 2, the probe 5 is generally formed in a substantially cylindrical shape, and a disk-shaped electrode 5 </ b> A is disposed at the tip. In the probe 5, an ultrasonic transducer 5B is disposed in the cylindrical portion, and the electrode 5A vibrates at a predetermined frequency by the vibration of the ultrasonic transducer 5B. Here, the overall shape of the probe 5 is formed so that the resonance frequency of the ultrasonic transducer 5B is about 22 kHz. On the other hand, the electrode 5A is made of stainless steel so as not to change due to sweat or the like.
[0016]
The probe 5 is connected to a cable so as to extend from both end electrodes of the vibrator 5B so that the vibrator 5B can be driven by the main body 2, and the cable is connected to the main body 2 via a predetermined connector. Has been made. The electrode 5A side electrode of the vibrator 5B is electrically connected to the electrode 5A, so that a voltage can be applied from the main body 2 to the electrode 5A.
[0017]
In the main body 2, the drive unit 3 drives the transducer 5 </ b> B of the probe 5. That is, the main body 2 supplies commercial power to the drive unit 3 and the electric field forming unit 4 via the power switch 6. As a result, the beauty tool 1 is activated by operating the power switch 6.
[0018]
In the drive unit 3, the rectification unit 7 starts operation by operating the drive unit switch 8, rectifies the commercial power supply, and generates various power sources necessary for the operation of the drive unit 3. The control unit 9 operates with the driving power output from the rectifying unit 7, and varies the voltage of the driving power and outputs it to the oscillating unit 10 in response to the operation of the operation element arranged on the control panel of the main body 2. . The oscillating unit 10 is operated by the power source output from the control unit 9 and generates a drive signal having a frequency of 22 [kHz] to drive the vibrator 5B.
[0019]
As a result, the drive unit 3 is activated by operating the drive unit switch 8, and the electrode 5A of the probe 5 is vibrated at a frequency of 22 [kHz] with an intensity corresponding to the control of the power supply voltage in the control unit 9. Yes.
[0020]
Thus, in the beauty tool 1, the operation of the drive unit 3 is activated and pressed against the site of the probe 5 where the electrode 5A is to be treated, whereby the medicine previously applied to the site to be treated is caused by ultrasonic vibration of the electrode 5A. It is designed to be able to penetrate the skin efficiently.
[0021]
In the electric field forming unit 4, the power supply unit 12 starts operation by operating the electric field forming unit switch 13, and rectifies the commercial power supply to generate various power sources necessary for the operation of the electric field forming unit 4. The pulse oscillating unit 14 is operated by the driving power source, and generates a rectangular wave signal having a frequency of about 25 to 30 [Hz].
[0022]
The constant current output unit 15 intermittently raises an output voltage based on a DC voltage according to the rectangular wave signal. At this time, the constant current output unit 15 raises the output voltage so that the average value or peak value of the output current becomes a constant reference current value. The constant current output unit 15 varies the reference current value according to the amount of operation of the operation element 16 arranged on the control panel of the main body 2 and similarly responds to the operation of the switch 17 arranged on the control panel. Switch the polarity of the output voltage.
[0023]
The constant current output unit 15 switches its operation by operating the switch 18 and continuously outputs a DC voltage based on the previous reference current value instead of intermittent DC voltage output.
[0024]
The constant current output unit 15 directly outputs the output voltage to the connector arranged in the main body 2 on the cold side, while outputting it to the connector via the switch 20 on the hot side.
[0025]
The switch 20 selectively supplies the hot side of this output voltage to the connector 5A of the probe 5. In the beauty tool 1, the first electrode 21 that applies an electric field to the site to be treated is connected to the hot side of the output voltage via this connector, and the electrode 22 that is gripped by the subject to be treated is the cold side of the output voltage. Connected to.
[0026]
As a result, the beauty tool 1 can apply a DC voltage between the electrodes 21 and 22 intermittently or continuously by switching the switch 20 to the connector side. As a result, the beauty tool 1 applies the drug to the site to be treated and grips the electrode 22, and then presses the electrode 21 against the site to be treated, thereby applying an electric field to the site to be treated and efficiently applying the drug. It is designed to penetrate the skin.
[0027]
Alternatively, the switch 20 is switched to the probe 5 side so that a DC voltage can be applied intermittently or continuously between the electrode 22 and the electrode 5A of the probe 5 so that the site to be treated can be applied. An electric field can be applied while applying ultrasonic vibrations. When only ultrasonic vibrations are applied, the drug is applied to the skin much more efficiently than when only electric fields are applied. It is made to be able to penetrate.
[0028]
In this embodiment, a jelly-like liquid containing vitamins is applied as the drug.
[0029]
(2) Operation of Embodiment In the above-described configuration, in the beauty tool 1, supply of commercial power to the drive unit 3 and the electric field forming unit 4 is started by operating the power switch 6.
[0030]
In this state, when the drug is allowed to penetrate the skin only by applying an electric field, in the beauty tool 1, the electric field forming unit 4 starts operating by the operation of the switch 13, and the pulse oscillation unit 14 has a frequency of 25 to 30 [Hz]. Are generated. In the beauty tool 1, by operating the switch 20, an output voltage whose voltage rises intermittently in response to the rectangular wave signal is applied to the electrodes 21 and 22 through the connector. Thus, in the beauty tool 1, the drug is applied to the site to be treated and the electrode 22 is gripped, and then the electrode 21 is pressed against the site to be treated, whereby an electric field is applied to the site to be treated to ionize the drug. Can penetrate the drug.
[0031]
At this time, in the beauty tool 1, by applying an electric field between the electrodes 21 and 22 by intermittent output of DC voltage, the absorption efficiency of the medicine is improved as compared with the case of applying DC voltage continuously. Can be improved.

At this time, in the beauty tool 1, the polarity of the output voltage is switched by operating the switch 17, whereby the direction of the electric field applied to the site to be treated can be switched. Therefore, the polarity can be set according to the active ingredient of the drug to be absorbed by the skin, and this also improves the absorption efficiency of the drug compared to the case where an electric field is applied simply by the polarity in one direction. Can do.
[0033]
In addition, when the DC voltage is applied, an output voltage is generated by the constant current output unit 15 so as to obtain a current value corresponding to the operation amount of the operation element 16, so that the electric field can be variously changed as necessary. The absorption rate of can be controlled.
[0034]
Further, by operating the switch 18, a continuous DC voltage is applied to the electrodes 21 and 22 instead of intermittent DC voltage application, whereby the drug can be absorbed into the skin by the electric field under the same conditions as in the prior art. it can.

On the other hand, when the medicine is to be absorbed only by ultrasonic waves, in the beauty tool 1, the drive unit 3 starts operating by the operation of the switch 8 and corresponds to the power supply voltage output from the control unit 9. The vibrator 5B vibrates due to the strength, and the electrode 5A vibrates due to the vibration of the vibrator 5B. As a result, in the beauty tool 1, after applying the medicine to the site to be treated, the electrode 5 </ b> A is pressed to apply ultrasonic vibration to the site to be treated, and the medicine is absorbed by the skin by this ultrasonic vibration. be able to.
[0036]
At this time, in the beauty tool 1, the electrode 5A is vibrated at a frequency of about 22 [kHz] which is much lower than that of the conventional device, and thereby, the drug can be absorbed into the skin much more efficiently than the conventional device. .
[0037]
On the other hand, when the medicine penetrates the skin by both ultrasonic waves and electric fields, the operations of the drive unit 3 and the electric field forming unit 4 are activated by the operation of the switches 8 and 13, and the electrodes 21 are activated by the operation of the switch 20. Instead, the hot side of the output voltage generated by the electric field forming unit 4 is supplied to the electrode 5 </ b> A of the probe 5.
[0038]
Thus, in the beauty tool 1, a DC voltage is applied intermittently or continuously between the electrode 5A that vibrates at a frequency of about 22 [kHz] by the vibrator 5B and the electrode 22 that is held by the patient to be treated. Can do. Thus, in the beauty tool 1, after applying the medicine to the site to be treated and holding the electrode 22, the electrode 5A of the probe 5 is pressed against the site to be treated, and an electric field is applied in a state of being vibrated by ultrasonic waves. As a result, the drug can penetrate into the skin much more efficiently than in the past.
[0039]
(3) Effects of the Embodiment According to the above configuration, the drive unit 3 that vibrates the electrode 5A of the probe 5 together with the vibrator 5B is housed and disposed in the main body 2, and the electric field formation disposed in the main body 2 is formed. By applying a DC voltage between the predetermined electrode 22 and the electrode 5A of the probe 5 by the unit 4, an electric field can be applied in a state in which the treatment site is vibrated by ultrasonic waves. Compared with this, the drug can penetrate into the skin much more efficiently.
[0040]
Further, at this time, even when this electrode 5A is vibrated at a frequency of about 22 [kHz] which is lower than that of the prior art, the drug can be penetrated into the skin more efficiently than in the past.
[0041]
Furthermore, by applying a direct voltage between the electrodes 5A and 22 intermittently, the drug can penetrate into the skin more efficiently than in the past.
[0042]
(4) Other Embodiments In the above-described embodiment, the case where the electrode 5A of the probe 5 is vibrated at a frequency of about 22 [kHz] has been described. However, the present invention is not limited to this, and the frequency of 20 [kHz]. ] It can vibrate in the range of -25 [kHz], and can infiltrate a chemical | medical agent more efficiently compared with the former practically enough. This is a comparison with the conventional case where only ultrasonic waves are applied.
