The NSS Military Field Stimulator (MFS) ((510)K140530) is a percutaneous nerve field stimulator (PNFS) system, which is used in a target population of acute and/or chronic pain. The NSS MFS is a battery-operated micro-stimulation appliance weighing approximately 5 grams designed as a disposable product for a single use. The NSS MFS is placed behind the patient’s ear and connected to stimulation needles on the auricle. The NSS MFS offers regular therapy over several days. The appliance transmits low-frequency electric pulses to exposed nerve endings.
An electrically-powered unit designed to be used specifically to apply electrical stimuli to acupuncture sites (electroacupuncture). It is an external low-intensity, low frequency pulse (usually 1 to 100 pulses per second), multimode generator intended to connect to acupuncture electrodes. The electrodes may be placed either on the skin, or through acupuncture needles that penetrate the skin at the acupuncture points. Some may use a probe to detect the acupuncture sites using visual or audio signals.
