Intermediate-frequency-modulated low frequency sonophoresis system

Abstract

The invention discloses an intermediate-frequency-modulated low frequency sonophoresis system. The intermediate-frequency-modulated low frequency sonophoresis system comprises a power supply module, a signal generating module, a control module, a digital switch module, a power amplification module, an output module and a man-machine interaction module. The power supply module is electrically connected with the signal generating module and the control module, the signal generating module is sequentially electrically connected with the power amplification module and the output module, and the control module is electrically connected with the digital switch module and the man-machine interaction module respectively. According to the intermediate-frequency-modulated low frequency sonophoresis system, intermediate frequency signals are modulated into low frequency ultrasound driving signals to produce a power source for medicine sonophoresis with modulated low frequency ultrasonic waves as positioning treatment, and accordingly, advantages such as strong penetrating power, low reentry rate and little thermal transition can be obtained; an intermediate-frequency focus is used for taking place of a low-frequency focus, so that the volume of equipment application components is reduced and further requirements of accurate, flexible, simple, convenient and safe use and operation can be achieved and effects of sonophoresis treatment can be better.

Description

technical field [0001] The invention belongs to ultrasonic medical equipment, in particular to an ultrasonic drug penetration system with intermediate frequency modulation and low frequency. Background technique [0002] In recent years, the research on drug target delivery technologies and methods to promote the accumulation of drugs in local tissues and cells has been widely carried out. The research directions that have been carried out so far mainly focus on three aspects: pharmacy methods, physical methods, and methods combining pharmacy and physics. Among them, ultrasonic drug penetration technology, as the main physical method, has become a hot spot in research and development. [0003] In the past, ultrasound was mainly used to promote the transdermal absorption of drugs (sonophoresis), which refers to the process of using ultrasound to promote drugs to penetrate through intact living skin and enter soft tissues. Most of this method is to use medium-frequency ultra...

AI Technical Summary

Problems solved by technology

Therefore, the source crystal that produces low-frequency ultrasound needs to ensure a relatively large thickness, coupled with a full set of transducer counterweights, amplification components, and a cooling system, a practical ultrasonic output treatment unit is bulky and weighs several kilograms. will bring great difficulties to clinical application

This technical bottleneck has seriously hindered the research and development of low-frequency ultrasonic medical device products. Therefore, it is particularly important to find a technical solution that can not only reflect the advantages of low-frequency ultrasound, but also break through the constraints of large volume and weight of the transducer.
