HR2003A Ultrasonic Physical Therapy Device

I. Working Principle and Application Scope of HR2003A Ultrasonic Physiotherapy Device: 

 A high-tech product that utilizes the high-frequency mechanical effects, thermal effects, and physicochemical effects of ultrasound for physical therapy on the human body. Ultrasound can generate endogenous heat in tissues, leading to local vasodilation, accelerated blood flow, enhanced metabolism, reduced muscle tension, alleviated pain, and increased extensibility of connective tissues. 

 II. Product Features: 

 1. 8-inch LCD screen for real-time display of various treatment data. 

 2. Compact size, lightweight, and simple operation. 

 3. Dual treatment heads for increased treatment area or simultaneous treatment of two patients. 

 4. Automatically generates treatment modes based on treatment depth, disease stage, and treatment area. 

 6. Features both pulse and continuous treatment modes. 

 7. 10 levels of sound intensity and 6 levels of time adjustable manually. 

 8. Treatment heads are designed with immersion protection (IPX7) and can be used for underwater ultrasound therapy. 

 9. Treatment head load protection with visual and auditory alerts when contact with the skin is poor or the timer ends, and automatically stops working. 

 10. Treatment heads feature over-temperature protection to prevent overheating. 

 11. Complies with the specific safety standard GB9706.205-2020 for ultrasonic physiotherapy devices. 

 12. Complies with the general safety standard GB9706.1-2020. 

 13. Complies with the electromagnetic compatibility standard YY9706.102-2021. 

 14. Complies with the environmental test standard GB/T 14710-2009.
