Description

Screen display interaction method for laboratory ultrasonic biological treatment
Technical Field
The invention relates to an ultrasonic biological treatment system, working software, a process and a method for a laboratory.
Background
The laboratory device, the process and the method of ultrasonic biological treatment still belong to the modes of single-frequency treatment, group comparison and induction effect at present. The current laboratory method of ultrasonic biological treatment is as follows: by setting or selecting a certain operating frequency of the ultrasonic wave generating apparatus in advance, the ultrasonic wave of the frequency is applied to the treatment object. However, the processing rate of the ultrasonic waves to the object is highly related to the ultrasonic frequency, and the ultrasonic frequency is different, so that the processing efficiency is greatly different; furthermore, the type of biological cells to be treated is highly correlated with the frequency of ultrasonic waves, and different biological cells have greatly different sensitivities to ultrasonic waves of different frequencies. This makes the determination of the primary ultrasonic frequency of the conventional ultrasonic biological treatment method blind, and further makes the additional ultrasonic frequency analysis and determination dependent. The actual working process is as follows: processing conditions of certain biological cells under different frequencies are utilized to carry out sub-band comparison and analysis determination to obtain related data; in later work, the appropriate ultrasound frequency was determined empirically, using the data for that particular object. This has been a common practice. Essentially, such a method cannot guarantee that the working ultrasonic frequency is the efficient optimal frequency for the object, and cannot perform precise fine frequency adjustment on different objects, and the accumulated experience is not the optimal process; moreover, the method not only consumes a lot of manpower, financial resources and material resources in the initial stage, but also frequently requires observation, adjustment and maintenance in the lifetime. In view of the above, there is a need to develop a new and efficient strategy for ultrasound bioprocessing that does not follow the inefficient procedure of first cross-band comparison, analysis to determine the ultrasound frequency, and then empirically determining the desired frequency, but rather makes the process of determining the desired frequency maximally efficient and automated. The scheme for solving the problems can be divided into a multi-body integrated networking visual structure experimental device, a process and a method, or a multi-frequency integrated visual structure experimental device, a process and a method.
