Frequency optimal control method for ultrasonic biological treatment

Abstract

The invention relates to a frequency optimal control method for ultrasonic biological treatment. In the method, the ultrasonic biological treatment process is controlled by utilizing a wide-frequency domain ultrasonic power supply device by adopting an operation strategy of multiband sequential search, catching and locking the optimal processing frequency. When the domain ultrasonic power supply device is in running, energy converter vibration boards matched with mid-band frequency are configured in sequence according to the frequency search directions of frequency bands in the working frequency domain of the ultrasonic power supply device; by the coordination and the control (general control, display and operating parameter setting function, a frequency sweep mode and a power given function) of a control terminal, frequency sweep is carried out on upper limit frequency defined frequency bands and lower limit frequency defined frequency bands; the upper limit frequency and the lower limit frequency of each frequency band are manually set or automatically continuously spliced by referring to the natural frequency of the energy converter, and the frequency sweep mode is manually or automatically set.

Description

Frequency Optimal Control Method of Ultrasonic Biological Treatment Technical field The invention relates to an ultrasonic biological treatment method. Background technique Ultrasonic biological treatment methods are generally: by determining or selecting a certain processing frequency of ultrasonic waves in advance, configuring ultrasonic generating equipment and its transducers (vibration plates), and then acting on the treatment object with working ultrasonic waves of this frequency. 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 ultras...
