Frequency searching and controlling method of ultrasonic biological treatment

Abstract

The invention relates to a frequency searching and controlling method of ultrasonic biological treatment. In the method, a wide frequency domain ultrasonic power device is utilized, and an operation policy with an optimal treatment frequency is searched, caught, controlled and locked by adopting a multi-band treatment sequence. During operating, in the working frequency domain of the ultrasonic power device, an energy converter, an amplitude transforming rod and a (tool head) vibrator which are matched with a central frequency of frequency bands are sequentially arranged along a frequency band frequency searching direction; through coordinating and controlling by a control (master control, display and operation parameter setting functions and frequency scanning mode and power given functions) terminal, synchronous frequency scanning is carried out on an upper limit frequency definition frequency band and a lower limit frequency definition frequency band; and by taking the natural frequency of the energy converter as a reference, the upper limit frequencies and the lower limit frequencies of all the frequency bands and the scanning modes can be manually set and also be automatically and continuously connected, thus various biological cells, article surface stains, pollutions and dirt can receive ultrasonic actions with a proper frequency and are locked on the frequency so as toimprove the treatment efficiency in multiples.

Description

Technical field [0001] The invention relates to an ultrasonic biological treatment method. Background technique [0002] The existing ultrasonic biological treatment method is: by setting or selecting a certain working frequency of the ultrasonic generating equipment in advance, and then using the ultrasonic frequency of this frequency to act on the treatment object. However, the processing rate of ultrasonic waves on objects is highly correlated with ultrasonic frequency, and the processing efficiency varies greatly with different ultrasonic frequencies; moreover, the type of biological cells to be processed is highly related to ultrasonic frequency, and different biological cells are sensitive to different frequency ultrasonic waves. very different. This has caused the blindness of the initial ultrasonic frequency determination in the existing ultrasonic biological treatment method, and further, the additional ultrasonic frequency analysis and determination form dependenc...

Problems solved by technology

In essence, such a method cannot guarantee that the working ultrasonic frequency is the optimal frequency for the object, nor can it perform precise and fine frequency adjustments for different objects, and the accumulated experience is not the best process; in addition, the The method not only consumes a lot of manpower, financial resources and material resources in the initial stage, but also often requires observation, adjustment and maintenance during the use period.
