Reletex – wrist-worn neuromodulation device provides drug-free treatment for nausea and vomiting

Depending on drugs to get rid of nausea or vomiting is not a long-term solution, there might be some other side effects if you’re too much dependent on drugs. Here comes a wrist-worn neuromodulation device, called the Reletex, which provides you a drug-free way for treatment of nausea and vomiting.

Wrist-worn stimulation devices are good adjuncts for the treatment of nausea or vomiting, although they might not be the most effective or cost effective ones. Basically, the device generates electrical signals that affect the brain’s perception of nausea.

The Reletex is an FDA-approved device and a product of Chicago based Neurowave Medical Technologies. More details about the Reletex are as follows. A video is also attached below for your consumption.

Reletex generates a proprietary programmed pulse that stimulates the neurons in the median nerve pathway creating an action potential. The cascading action potentials are sent via median nerve into the brachial plexus which then enter the cervical spinal cord and travel into the spinothalamic tract which sends signals to the brainstem. The action potentials created by Reletex™ reach the brainstem emetic control center.

The action potentials activate various key neurons within the brainstem emetic (vomiting) control center and may override or stimulate some of the gated ion channel movements created by emetic agonists. Neurons within the emetic center then create an action potential that regulates the GI tract via the vagus nerve. The interstitial cells of Cajal (ICC), known as the pacemakers of the GI tract, receive the action potentials via the vagus nerve.

The waveform of the action potentials sent to the ICC now directly affects the force and frequency of muscle contraction in the stomach. The now regulated stomach contractions allow relief from nausea and vomiting.
