Vomiting triggers can come from various forms of activities (car ride, pregnancy, medication).

The vomiting center becomes activated and sends signals to the gastrointestinal tract.

The gastrointestinal tract receives the signals, contracts abnormally, and causes vomiting.

Advanced TEAS Targeted Neuromodulation

TEAS stands for Transcutaneous Electrical Acupoint Stimulation, the advanced targeted neuromodulation technology at the core of EmeTerm. Designed as a non-invasive, device-based approach, it delivers targeted electrical stimulation through a wearable wristband format for drug-free nausea support.

  • EmeTerm is a wristband with electrode pads that deliver high-precision electrical impulses via the median nerve on the underside of the wrist.
  • These signals, modulated to inhibit the vomiting center, travel toward their target located in the medulla oblongata.
  • By inhibiting the vomiting center from signaling via the vagus nerve to the gastrointestinal system, EmeTerm can reduce the symptoms of nausea and vomiting.

Clinical Evidence You Can Trust for Nausea Relief

In a randomized clinical trial published in JAMA Surgery, EmeTerm showed superior control of moderate to severe postoperative nausea and vomiting, with a 77.6% 2-hour remission rate and a 12.2% 24-hour relapse rate.
