The working principle of the medium frequency electrotherapeutic apparatus:
As a low-frequency modulation intermediate frequency electrotherapeutic apparatus uses the intermediate frequency signal generated by the intermediate frequency oscillator. After the low-frequency current modulates the intermediate frequency current, the current whose amplitude and frequency change with the amplitude and frequency of the low-frequency current is called the modulated intermediate frequency current. The modulated intermediate frequency current has both the characteristics and therapeutic effects of the low-frequency current and the intermediate frequency current. It can be used to simulate the effect of traditional Chinese medicine acupuncture and moxibustion, and the method of electrical stimulation is used for treatment. It acts on the ganglia, can produce reflexes, and has the functions of contracting muscles, relaxing tendons, and promoting blood circulation, and analgesia.
The scheme of DWIN medium frequency electrotherapeutic apparatus:
The whole scheme adopts DWIN dual-core T5L0 as the control center of the whole machine, GUI core realizes human-machine interaction with no code, and controls the output of intermediate frequency pulse therapy wave in different gears and modes through the PWM and AD feedback of the OS core. It supports human contact detection, low battery automatic alarm and other functions
Features:
1)Accurately multi-speed frequency adjustable: supports up to 1700 levels of adjustable intensity, 1~10KHz adjustable intermediate frequency output frequency, and 10~480Hz modulation frequency.
2) Output mode customization: modify the configuration file through SD card to customize the working frequency of each mode.
3) Rich interface elements: DGUSII interface secondary development with no code can realize the setting and display of work intensity, mode, time, as well as brightness adjustment, automatic screen time setting, boot animation, screen saver animation effect, etc.
4) Rechargeable: built-in rechargeable lithium battery, with Mini USB charging interface.
Advantages:
1) Single chip solution;
2) Dual-core chip, GUI core supports no code host computer design engineering interface; OS core boost, output control patent, no transformer required;
3) Support display solutions of various sizes and resolutions such as 4.3 inches to 10.4 inches;
4) Built-in 16MB FLASH, expandable to 176MB, can store multiple pictures, design touch and display as large icons, convenient for middle-aged and elderly people and people with poor eyesight, backlight adjustable screen brightness;
5) Intelligent battery management, low battery charging reminder, shutdown reminder.
