Abstract
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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
80 words
In a device for treatment of sleep apnea by preventing the flow of air through a user's mouth while engaging the tip of the user's tongue in a socket, the engagement resulting from creation of suction in the socket, the improvement comprising: detection means connected to the device for generating an electrical signal when the tongue is disengaged from the socket; and alarm means operably coupled to said detection means for generating an alarm in response to said electrical signal.
Claim 2
Dependent Claim
80 words
In a device for treatment of sleep apnea by preventing the flow of air through a user's mouth while engaging the tip of the user's tongue in a socket, the engagement resulting from creation of suction in the socket, the improvement comprising: detection means connected to the device for generating an electrical signal when the tongue is disengaged from the socket; and alarm means operably coupled to said detection means for generating an alarm in response to said electrical signal.
Claim 3
Dependent Claim
123 words
In a device for treatment of sleep apnea by preventing the flow of air through a user's mouth while engaging the tip of the user's tongue in a socket to hold the tongue in a forward position within the mouth, the engagement resulting from tongue created suction in the socket, the improvement comprising: a detection system operatively coupled to the socket and responsive to the engagement of the user's tongue within the socket, an alarm system having an alarm state and a stable state, operatively coupled to said detection system, the operative coupling causing the alarm system to be in the stable state when the tongue is within the socket and in the alarm state when the tongue is not within the socket.
Claim 4
Dependent Claim
123 words
In a device for treatment of sleep apnea by preventing the flow of air through a user's mouth while engaging the tip of the user's tongue in a socket to hold the tongue in a forward position within the mouth, the engagement resulting from tongue created suction in the socket, the improvement comprising: a detection system operatively coupled to the socket and responsive to the engagement of the user's tongue within the socket, an alarm system having an alarm state and a stable state, operatively coupled to said detection system, the operative coupling causing the alarm system to be in the stable state when the tongue is within the socket and in the alarm state when the tongue is not within the socket.
