Problems solved by technology

Existing medical equipment generally has a relatively single function, and a certain type of equipment generally treats a certain disease accordingly. As a result, there are many kinds of equipment of different types, specifications, and purposes in the market, which makes medical companies design and manufacture Each product requires a considerable amount of energy, the correlation between various products is small, and the reusability rate is too low, which wastes the manpower and financial resources required for enterprise development and the product development cycle has not been effectively controlled.
For product users, they need to purchase different types of treatment equipment for patients with different symptoms. Not only the purchase cost cannot be controlled, but also the later maintenance of the equipment is extremely troublesome, which also puts forward higher requirements for maintenance personnel.

Embodiment 2

[0028] like image 3 As shown, the ultrasonic module generates a 1.2M high-frequency signal from the internal PWM module of the STM32 series microcontroller, and outputs it to the ultrasonic transducer drive circuit. Since different frequency transducers have different therapeutic effects, the device may be equipped with a variety of different frequencies. Transducer, and this design uses software to modify the frequency, which simplifies the hardware design, and the frequency switching is very convenient, just use the program to modify the control parameters. The ultrasonic module is also designed with a red light drive circuit to cooperate with photon treatment, the recovery effect is more significant;

Embodiment 3

[0030] like Figure 5 As shown, the DA module inside the STM32 outputs a sinusoidal signal with a fundamental wave of 1-10K through DMA through the DA module of the intermediate frequency electrical stimulation module. After low-frequency modulation, the power is amplified by the audio power amplifier. The specific model of the audio power amplifier is TPA3118, and then through the output transformer for step-up isolation, then contact the patient for treatment. The circuit is characterized by the use of digital power amplifier with high efficiency and simple structure. The whole circuit does not need special heat dissipation treatment, simple and reliable. Perform real-time calculations for the AD module inside the single-chip microcomputer to ensure energy control and safety protection during the treatment process, and another PWM signal controls the air pump through the power switch to perform negative pressure adsorption control.
