Intelligent ultrasonic physiotherapy device through blood pressure signal control and implementation method thereof

Abstract

The invention discloses an intelligent ultrasonic physiotherapy device through blood pressure signal control and an implementation method of the device and belongs to the technical field of ultrasonic therapy instruments. The device comprises a system control module, a DDS numerical control frequency source module, a pulse blood pressure acquiring and processing module, a valve module, a high-frequency generator module, an ultrasonic transducer and a frequency monitoring module, wherein the DDS numerical control frequency source module is used for generating ultrasonic frequency square wave signals, the pulse blood pressure acquiring and processing module is used for measuring high blood pressure and low blood pressure of a human body and using the average value of the high blood pressure and the low blood pressure as a parameter for controlling ultrasonic output power, and then pulse signals are acquired and processed by the pulse blood pressure acquiring and processing module so that TTL level control signals synchronous with pulses can be generated. According to the intelligent ultrasonic physiotherapy device through blood pressure signal control and the implementation method of the device, the blood pressure signals of the human body are used as the parameters for controlling the ultrasonic output power, the ultrasonic output power can be adjusted according to the physical conditions of the human body, the ultrasonic therapy application range can be wider, and the therapeutic effect can be better.

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...

AI Technical Summary

Problems solved by technology

[0005] However, some ultrasonic therapeutic instruments may experience unstable resonance frequency during use, or even stop working due to frequency drift, which greatly reduces the service life of the therapeutic instrument.

In addition, different constitutions, different causes of disease and different tolerances, the dose of ultrasound used, that is, the sound intensity and the use time are different, but the power of most therapeutic instruments is constant, which limits the scope of use of therapeutic instruments
