<p>The present invention relates to a therapeutic device emitting multi-frequency ultrasonic-waves, and more particularly, to a therapeutic device simultaneously or selectively using the ultrasonic-waves of multi-frequency bands from one ultrasonic-wave vibrator, wherein ultrasonic-wave treatment is performed by bringing the ultrasonic-wave vibrator into contact with a skin surface and cell of human face and whole body. The therapeutic device uses the ultrasonic-wave vibrator emitting the ultrasonic-waves of multi-frequency bands instead of the ultrasonic-wave vibrator emitting a conventional ultrasonic-wave of a single frequency band. Specifically, one ultrasonic-wave vibrator may include a high frequency generating ultrasonic-wave vibrator for generating a wave (in a high frequency band) with a broad amplitude and short frequency and a low frequency generating ultrasonic-wave vibrator for generating a wave (in a low frequency band) with a narrower amplitude and longer frequency than those of the high frequency generating ultrasonic-wave vibrator, to selectively or simultaneously generate the ultrasonic-waves in the high frequency band and low frequency band. Accordingly, a dermatological hospital and a skin massage shop may perform treatment through an optimized ultrasonic-wave by using the minimum number of ultrasonic-wave therapeutic devices without purchasing various kinds of ultrasonic-wave therapeutic devices, so that an individual, a dermatological hospital, and a skin massage shop can minimize purchase costs for the ultrasonic therapeutic device and also reduce cost required for maintenance and the like. Also, the ultrasonic-waves of low frequency band and high frequency band may be alternately used to effectively treat specific lesions such as acne.</p> |
