  • Patent number: 10271992
    Abstract: A portable device for noninvasively treating Meniere's disease and similar conditions by introducing pressure pulses into an ear canal to vibrate auditory ossicles through a tympanic membrane. The device includes a pump unit for generating the pressure pulses, wherein the pump unit includes a Voice Coil Motor and a diaphragm pump that is driven by the Voice Coil Motor; an earpiece for transmitting the pressure pulses to a tympanic membrane; a controller for controlling the pump unit; and an alarm lamp. When the device detects no pressure pulses being generated even when the pump unit is operated, the alarm lamp is lit and an error message is displayed on the indicator, and when the device detects the earpiece being disconnected from the ear of the user, the microcomputer stops counting the time elapsed and the alarm lamp is lit and an error message is displayed on the indicator.
