NPD-4AE Traditional Chinese Medicine Directional Permeation Therapy Device Technical Parameters and Performance

Technical Parameters

1. Treatment Current: D-created asymmetric superconducting low-to-medium frequency encoded current, which has dual effects of multi-encoding and dynamic modulation;

2. Control Method: Standard button control, with various physical parameters displayed on the LCD screen;

3. Four Treatment Modes:

a) Low-to-medium frequency asymmetric directional drug delivery therapy;

b) Low-to-medium frequency symmetric massage electrotherapy;

c) Low-to-medium frequency asymmetric directional drug delivery + massage electrotherapy + thermotherapy + magnetotherapy;

d) Low-to-medium frequency symmetric massage electrotherapy + thermotherapy + magnetotherapy;

4. Output Waveform: Multi-modulated symmetric wave during massage, multi-modulated asymmetric wave during drug delivery;

5. Operating Frequency: Medium frequency: 2000Hz±15%, Low frequency modulation: 95 Hz±15%;

6. Pulse Width: 0.220ms±20%;

7. Modulation Method: Dynamically adjustable duty cycle;

8. Output Channels: 2 channels (treating 2 patients simultaneously);

9. Output Intensity (500Ω load):
Medium frequency output current: 0~70mA
Output intensity adjustment: 0~99 (100-step adjustment)
Maximum pulse current: ≤100mA;

10. Output and Protection Functions:
Output current automatically stabilizes at the set value; parameters remain unaffected when load impedance varies from 100Ω to 1KΩ. The device includes multiple safety protections such as electrode detachment detection, output lock, short-circuit tolerance, and double insulation isolation;

11. Timing: Automatically set to 25 minutes by the system, or manually adjustable from 1 to 60 minutes;

12. ★ Thermotherapy Temperature: Adjustable between 25°C and 50°C;

13. ★ Thermotherapy Power: 0~5 (6-step adjustment), with seasonal temperature presets for spring, summer, autumn, and winter;

14. Preset Programs: Includes four expert-selected treatment programs (A-B-C-D), allowing flexible selection based on patient needs;

15. ★ Magnetotherapy Function: Dynamic magnetic field with therapeutic effects;

16. Power Supply: AC 220V 50Hz±10%;

17. Power Consumption: ≤80VA;

18. Continuous Operation Time: ≥4 hours;

19. Device Lifespan: ≥6 years.
