Device Description
ComboRehab is four channels combination unit, can provide muscle stimulation, ultrasound, biofeedback and combination therapy. This product is designed to offer a multiple choices for clinician in one compact and integrated package. A large control knobs located on the panel, allows clinician very easy to select different therapy mode and set therapeutic parameters. The award winning design offers a 5 inch Touch TFT LCD color display screen that can helps clinician to monitor the treatment information promptly. In the electrotherapy mode, it's freedom for clinician to select one, two, three or four channels into therapy. A comprehensive set of current waveforms is available, targeting both pain management and muscle stimulation applications; interferential (4-pole), premodulated (2-pole interferential), Russian, NMS (Pulsed mode, burst mode), high volt, TENS, Microcurrent and Direct current. The Ultrasound mode can be equipped with two applicators, 1cm² and 5cm². The applicators can operate in continuous or pulsed mode at an ultrasound frequency of 1 MHz or 3 MHz. The EMG mode can provide us detail information about the organ-specific properties of a muscle through surface EMG electrodes. EMG biofeedback activity can couple with triggered electrical muscle stimulation using selected electrotherapy waveforms for the maximum benefit in muscle re-education. The combination electrotherapy is used for the management of pain and muscle spasm. All functions of 1 or 3 MHz Ultrasound can be combined with Interferrential, Premodulated, Asymmetrical Biphasic. NMS, NMS burst mode, and High Voltage pulsed Current.
More Information

Not Found

No
The device description and intended use focus on standard therapeutic modalities (ultrasound, electrotherapy, EMG) with no mention of AI or ML algorithms for analysis, treatment planning, or any other function. The performance studies listed are focused on electrical and safety standards, not AI/ML performance metrics.

Yes
The device details multiple therapeutic applications, including pain relief, muscle spasm reduction, increasing range of motion, muscle re-education, and preventing disuse atrophy, which are all aimed at treating specific medical conditions.

No

The device is primarily a therapeutic device, providing various forms of electrotherapy and ultrasound for treatment purposes (e.g., pain relief, muscle relaxation, muscle re-education). While it has an "EMG mode" that provides information about muscle activation and force, this information is used for "retaining of muscle activation," "coordination of muscle activation," and "relaxation/muscle re-education," which are therapeutic goals. The EMG is a biofeedback tool to aid in rehabilitation, not for diagnosing a condition.

No

The device description clearly states it is a "four channels combination unit" that provides muscle stimulation, ultrasound, and biofeedback, and mentions physical components like "control knobs," a "Touch TFT LCD color display screen," and "applicators." This indicates it is a hardware device with integrated software, not a software-only medical device.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to detect diseases, conditions, or infections.
  • Device Function: The description clearly states the device is a "four channels combination unit" providing "muscle stimulation, ultrasound, biofeedback and combination therapy." Its intended uses are focused on therapeutic applications like pain relief, muscle rehabilitation, and increasing range of motion.
  • Lack of Sample Analysis: There is no mention of the device analyzing any biological samples from the patient. Its actions are external applications of energy (ultrasound, electrical stimulation) or measurement of physiological signals (EMG) for therapeutic or diagnostic purposes in vivo.
  • Relevant Standards: The listed standards (IEC 60601-1, IEC 60601-1-2, IEC 60601-2-10, IEC 60601-2-5, IEC60601-2-40) are for medical electrical equipment, nerve and muscle stimulators, ultrasonic physiotherapy equipment, and electromyographs, all of which are consistent with a therapeutic and diagnostic device used on the body, not for analyzing samples from the body.

Therefore, this device falls under the category of therapeutic and diagnostic medical devices used directly on the patient, not In Vitro Diagnostics.

8. Conclusions:

The proposed device has the same intended use and similar characteristics as the predicate device, the CT1000 SonicStimu Device and Vectra Genisys. Moreover, bench testing, and safety repor documentation supplied in this submission demonstrates that any differences in their technological characteristics do not raise any new questions of safety or effectiveness. In the other words, those engineering difference do not affect the intended use or alter the fundamental scientific technology of the device.

Thus, ComboRehab Device is substantially equivalent to the predicate device.
