I. EHA-I Electrothermal Acupuncture Therapy Apparatus Product Overview

This product, the EHA-I Electrothermal Acupuncture Therapy Apparatus, is a novel device that utilizes electrothermal needles specifically designed for the apparatus to perform acupuncture treatment. In traditional Chinese acupuncture therapy, it achieves the therapeutic effects of both acupuncture and warm needle moxibustion. It effectively addresses the issue in ancient warm needle moxibustion where the moxa wool is burned on the needle handle but heat conduction to the needle body and tip is suboptimal.

II. Scope of Application

Applicable for electrothermal acupuncture treatment of joint pain, swelling, and heaviness symptoms caused by knee Bi syndrome (knee osteoarthritis).

III. Operating Conditions

1. Ambient temperature: 5°C to 40°C

2. Relative humidity: ≤80%

3. Atmospheric pressure: 500 hPa to 1060 hPa

4. Power supply conditions: AC 220V, 50Hz

5. Input power: 60VA

IV. EHA-I Electrothermal Acupuncture Therapy Apparatus Main Technical Parameters

1. Electrothermal needle appearance and dimensions: See Figure 1 and Table 1.

2. Electrothermal needle resistance: EHA-L60 type electrothermal needle is 9Ω, tolerance ±10%. EHA-L80 type electrothermal needle is 12Ω, tolerance ±10%.

3. Maximum temperature during electrothermal needle operation (in 26°C room temperature air) does not exceed 60°C.

4. Therapy apparatus output current: Maximum operating output current of the therapy apparatus does not exceed 200mA, tolerance ±10%.

5. Treatment time: 1-30min (graduation value 1min), tolerance ±10%.

6. Fuse: F2AL250V Φ5mm×20mm.

7. Safety type: Class I, BF type.

8. Operating mode: Continuous operation.

9. Number of output channels: 8 channels independent output.

10. Treatment method: Electrothermal acupuncture warm needle therapy.

11. Output open-circuit and short-circuit performance:

The apparatus has automatic detection functions for output open-circuit and short-circuit conditions. Under open-circuit or short-circuit conditions, the device protects itself. After the condition is resolved, the apparatus resumes normal operation.

12. External dimensions: 435mm×294mm×108mm.

13. Weight: 4.8kg±0.1kg.

14. The therapy apparatus has the following functions:

a) Has automatic detection function upon startup; the apparatus automatically stops working when the ambient temperature exceeds the 5°C to 40°C range;

b) Has automatic detection function for electrothermal needles and connecting wires;

c) Has automatic monitoring function for electrothermal needles and connecting wires during the treatment process;

d) Has functions for adjusting time, adjusting temperature, and display.

15. Continuous operating time: Not less than 4h.
