The device description details manual controls (knobs for wave, frequency, intensity, timer) and does not mention any automated or adaptive functions typically associated with AI/ML. There is no mention of AI, DNN, or ML in the provided text.
Yes
The "Intended Use / Indications for Use" states it is "indicated for use in the practice of acupuncture" and the "Device Description" calls it "an electro-acupuncture device for acupuncture therapy."
No
The device description clearly states it is an "electro-acupuncture device for acupuncture therapy" and is used to "stimulate" and "treat" patients. The "Indications for Use" section further supports this by stating it is for "use in the practice of acupuncture." It does not mention any function related to identifying, analyzing, or determining a medical condition, which are characteristic of diagnostic devices.
No
The device description explicitly states it is an electro-acupuncture device composed of a console, electrode cables, and powered by batteries, indicating it is a hardware device.
Based on the provided information, the Jiajian® CMN Stimulator is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for electro-acupuncture stimulation in the practice of acupuncture by qualified practitioners. This involves applying electrical stimulation to the body, not analyzing samples taken from the body.
- Device Description: The device is described as an electro-acupuncture stimulator with electrodes and controls for wave, frequency, intensity, and timer. It does not involve any components for collecting, processing, or analyzing biological samples.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD device, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing information for diagnosis, monitoring, or screening based on sample analysis
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information about a person's health. The Jiajian® CMN Stimulator is a therapeutic device that applies electrical stimulation to the body.

B. Substantial Equivalence Discussion
| Similarities between New device
and Predicate Device: | Intended use, input DC power, biphasic square waveform, Net charge,
adjustable frequencies and intensity, standards, at most 3 channels of
output |
|----------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Differences between New device
and Predicate Device: | The two devices have different weight, dimensions, output pulse width,
frequency range;
The predicate device has a battery level check button, while the new
device auto shut when the input power is less than 8.1V;
The new device outputs 3 modes of waveforms (continuous wave,
interrupted wave & Dense-disperse wave), while the predicate device
has only I mode of continuous wave |

Conclusion:
The new device and the predicate device have same intended use, input DC power, biphasic square waveform, zero net charge, complied standards, adjustable frequency and intensity.
The differences between the two devices are analyzed as following:
- Interrupted wave (Burst Mode) and Dense-disperse wave: The new device has burst mode which is composed of a continuous train of impulses with a small pause in between while the predicate device has continuous train of impulses. The Dense-disperse wave of new device is composed of a alternating frequency. But the basic characteristics of the Interrupted wave (Burst Mode) and Dense-disperse wave of the proposed device are consistent with the continuous wave, so this difference does not raise new types of questions of safety or effectiveness.
2 Maximum output voltage, maximum output current, output pulse width, frequency range:
The new device has higher maximum output voltage and current than Predicate device. The output pulse width of new device is higher than the Predicate device while the frequency range is lower than the Predicate device.
Because the physiological effectiveness of stimulation is primarily dependent on delivered charge, and the maximum phase charge per pulse of the new device is a little higher than the Predicate device, so it can achieve the effectiveness. And the maximum output Charge is within the safety limit.
Therefore this difference does not raise new types of questions of safety or effectiveness.
- Maximum power density, total maximum RMS current passed through the body:
Maximum power density is smaller than the predicate device. Though the new device has 6 channels of output, only 3 channels at most could be used on single patient, and the total maximum RMS current of the new device passed through the body is smaller than the predicate device. So the differences would not raise new safety concerns.
To sum up, the new device Jiajian® CMN Stimulator is substantially equivalent to Predicate device of ES-130 (K081943).
4. Safety and Effectiveness of the device
Jiajian® CMN Stimulator was tested and found to meet the safety standards of:

-
IEC 60601-1-2:2007, Medical Electrical Equipment - Part 1-2: General Requirements for basic safety and essential performance - Collateral Standard: Electromagnetic Compatibility -- Requirements and Tests
The output lead wires with Alligator type connectors used for Jiajian® CMN Stimulator were tested and found to comply with the safety standards of:
- IEC 60601-1, Medical Electrical Equipment - Part 1: General Requirements for Safety, 1988; Amendment 1, 1991-11, Amendment 2, 1995
The device was also tested basis on reduced battery level, and was found that the stimulus parameters were not significantly affected (less than ±10%).
The conclusion drawn from the testing is that the device is substantially equivalent to the predicate devices.

Dear Ms. Dong:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful, and not misleading.
If your device is classilied (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
