Ultrasonic wave and ion conduction transdermal medicament or cosmetic conduction device

Abstract

The invention discloses an ultrasonic wave and ion conduction transdermal medicament or cosmetic conduction device, which comprises a central processing unit, a signal generator, a piezoelectric ceramic, a pointed metal electrode and a booster circuit, wherein the central processing unit is used for receiving a control command and outputting a waveform control signal; the signal generator is used for generating high-frequency waves, low-frequency waves or high and low-frequency waves; the piezoelectric ceramic is used for converting electric energy into mechanical energy to generate mechanical vibration of corresponding frequency; the pointed metal electrode is used for making low-frequency current flow into skin in a concentrated way through an electrode tip and transmitting ultrasonic waves generated by the piezoelectric ceramic onto the skin through the electrode tip; and the booster circuit is used for providing a stable and appropriate voltage for an entire circuit system. In the device, ultrasonic wave and ion conduction methods are combined, so that medicament or cosmetic components with treatment effects are conducted into skin. Through the method, medicaments can be directly conducted into superficial focuses and have high concentrations and long acting time in local superficial tissues, and the administration amount can be decreased greatly; and moreover, the method is low in cost, and has small side effects.

Description

technical field [0001] The invention belongs to the technical field of drug or beauty product introduction, and in particular relates to an ultrasound and iontophoresis transdermal drug or beauty product introduction device. Background technique [0002] The existing iontophoresis method is generally unidirectional. The disadvantage of unidirectional import is that the current only flows in one direction, and the electrochemical reaction caused by the current flow will change the pH of the skin, which will easily cause skin damage. In addition, due to the existence of the stratum corneum of the skin, it is difficult for general molecules to penetrate the stratum corneum and enter the dermis. Therefore, relying solely on iontophoresis, the consistency of molecular penetration is poor and the penetration is small. Finally, the impedance of the skin increases with the decrease of the imported current, often in the small current range of the trapezoidal wave, the voltage of the...

Problems solved by technology

[0003] The purpose of the embodiments of the present invention is to provide an ultrasonic and iontophoresis transdermal drug or beauty product introduction device and method, which aims to solve the disadvantage of one-way introduction, which is that the current only flows in one direction, and the electrochemical reaction caused by the current flow makes the The pH of the liquid on the surface of the skin changes, which can easily lead to skin damage; due to the existence of the stratum corneum of the skin, it is difficult for general molecules to penetrate the stratum corneum and enter the dermis. The impedance of the skin increases with the decrease of the imported current, often in the small current range of the trapezoidal wave, and the voltage of the line cannot maintain the predetermined current amplitude.
