Description

Ultrasonic frequency detection method for ultrasonic biological treatment

[0001] The present invention relates to an ultrasonic frequency detecting method for an execution terminal of an ultrasonic biological processing operation.

Background technique

[0002] The processing rate of ultrasonic waves on objects is highly correlated with the ultrasonic frequency. The ultrasonic frequencies are different and the processing efficiency is very different. Moreover, the biological cell types of the treated objects are more highly correlated with the ultrasonic frequencies, different biological cells, and ultrasonic waves of different frequencies. Sensitivity is very different. This results in the blindness of the initial ultrasonic frequency determination of the existing ultrasonic biological treatment method, and further, the ultrasonic frequency analysis is performed to determine the formation dependence. The actual working process is: using the processing of a certain biological cell at different frequencies, performing sub-band comparison, analysis and determination to obtain relevant data; in the future work, the data of the specific object is used to empirically determine the appropriate ultrasonic frequency. This is already a custom. In essence, such a method does not guarantee that the ultrasonic frequency at work is the optimal frequency for the object, nor can it accurately and finely adjust the different objects. The accumulated experience is not the best process; The method not only consumes a lot of manpower, financial resources and material resources at the beginning, but also frequently requires observation, adjustment and maintenance during the period of use.

[0003] In view of this, it is necessary to develop a new and efficient strategy, so that the ultrasonic biological processing work will no longer follow the inefficient method of determining the ultrasonic frequency by sub-band comparison, analyzing and determining the required frequency, but The process of determining the required frequency is carried out to be as efficient and automated as possible. An efficient solution to this type of problem is the integrated structure of ultrasonic bioprocessing frequency search control, and the most difficult problem of the integrated structure is the broadband transduction matching technique, ie, the wide frequency band at several different center frequencies as the search frequency changes. How to realize the frequency band search and conversion matching of the resonant network between the vibration plate and the driving power source. For such a complex matching structure, control is a more complicated and unavoidable problem, and obtaining frequency feedback signals is the primary problem of control. Furthermore, performing ultrasonic frequency detection of the terminal becomes a key and urgent problem to be solved. Different from the frequency detection of the single frequency ultrasonic execution terminal, the frequency detection of the ultrasonic biological processing frequency search and control integrated system needs to be performed on the dynamic execution terminal. Therefore, it is necessary to develop an unconventional detection method suitable for the system of the continuous switching process. technical problem

[0004] In order to make the ultrasonic biological treatment process measurable and controllable, wide-band search and control in the bio-mechanical-electrical integrated processing system is realized.
