Patients in infrared physiotherapy, you can adjust the size of the aperture through the knob on the top of the machine, change the intensity of irradiation, to achieve a more comfortable physiotherapy temperature. At the same time, the lower temperature probe can detect the real-time temperature of the physical therapy irradiation site, so as to avoid the damage to the patient's skin caused by long-term irradiation and prevent the patient from being scalded at low temperature. When the infrared probe detects that the temperature is too high, the aperture in the lampshade will automatically narrow to reduce the transmission of infrared light. At the same time, the steering gear on the main support rotates to control the head to move backward away from the user to prevent burns. The instrument has a variety of built-in physiotherapy modes, combined with mobile phone software to control the movement of the main machine and aperture adjustment for customized physiotherapy selection.
