Abstract
A monitor system is provided for a device used in the treatment of sleep apnea. The device engages the user's tongue in a socket. The tongue is thereby held in a forward position, increasing the size of the air passageway, while at the same time flow of air through the mouth is blocked. The monitor is responsive to the position of the tongue in the socket and activates an alarm when the tongue slips out of the socket. One example of such a monitor includes circuitry with a thermistor. Thermistor temperature changes are used to generate a voltage that enables alarm and recording circuitry.
