Description

technical field

[0001] The invention relates to the field of ultrasonic therapy instruments, in particular to an intelligent ultrasonic physiotherapy device controlled by a blood pressure signal and an implementation method thereof. Background technique

[0002] Ultrasonic medical technology is a technology that uses ultrasonic waves to interact with the physical (mechanical) properties of tissues to image tissue or perform surgical treatment. In recent years, with the development of science and technology, ultrasonic technology has entered a new stage of development. Because of the advantages of no injury, no pain, and repeated inspection and treatment, it is especially suitable for soft tissue operations. Medical ultrasound equipment has been widely valued and developed rapidly. Such as ultrasonic lithotripsy, ultrasonic cosmetology and ultrasonic cancer treatment.

[0003] Ultrasonic therapy instrument is mainly composed of two parts: high-frequency power generator and...

Embodiment 1

[0078] Figure 6 For the concrete implementation of the work flow chart of the present invention, as Figure 6 As shown, when the device is working, the single chip microcomputer is first initialized to control the blood pressure signal acquisition. The collected blood pressure signals are high and low blood pressure values. The average value should be calculated by the single-chip microcomputer, and the average value should be used as a parameter to control the output of ultrasonic power. Also collect the pulse signal and use it as the trigger signal of the ultrasonic frequency square wave signal. DDS numerical control frequency source module is used to generate ultrasonic frequency square wave signal. In the valve module, when a pulse signal comes, the ultrasonic frequency square wave signal is triggered and input to the high frequency power generator module. After the relevant functions of the high-frequency power generator module are processed, the electric energy is co...
