Device Description
TENS & EMS Device is a pain management device with a combination of TENS and EMS therapy technology. It can stimulate healthy muscles in order to improve and facilitate muscle performance, and temporary relief of pain associated with sore and aching muscles in the upper and lower back, back of the neck, upper extremities (shoulder and arm), lower extremities (leg and feet) due to strain from exercise or normal household work activities by applying current to stimulate nerve. TENS & EMS Device (Model: LY-ET-01, LY-ET-04) has 3 modes (Model LY-ET-02 has 5 modes) and one channel, which provide electrical pulse stimulation through the electrode pads to the treatment area. The TENS & EMS Device has the operating elements of ON/OFF knob, Mode Selection button, Intensity adjustment Dial (or Intensity Increase button and Intensity decrease button) and Time Selection button which is user-friendly and easy to control. The device is equipped with electrode pads and electrode wire is used to connect the pads to the main unit. All the accessories can only be purchased by a local distributor.
More Information

No
The summary describes a standard TENS/EMS device with fixed modes and manual controls, and there is no mention of AI or ML in the device description, intended use, or performance studies.

Yes
The device is described as a pain management device used for temporary relief of pain associated with sore and aching muscles and for symptomatic relief and management of chronic pain, which falls under the definition of a therapeutic device.

No

Explanation: The device is described as a pain management device used for symptomatic relief, muscle performance improvement, and increased blood circulation by applying electrical stimulation. It does not mention any function related to diagnosing diseases or conditions.

No

The device description explicitly mentions physical components like electrode pads, electrode wire, a main unit with operating elements (knobs, buttons, dials), and states that accessories are purchased separately. It also details performance testing on the "final, finished product" which includes hardware. While software verification and validation are mentioned, the device is clearly a hardware-based TENS/EMS unit with integrated software for control, not a standalone software application.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The TENS & EMS Device described applies electrical stimulation to the body's surface for pain relief and muscle stimulation. It does not analyze any biological specimens.
  • Intended Use: The intended use clearly states the device is for temporary pain relief and muscle stimulation by applying current to the body. This is an external application, not an in vitro analysis.

Therefore, this device falls under the category of a therapeutic or physical medicine device, not an In Vitro Diagnostic device.
