System for monitoring sleep apnea
2010
The invention discloses a system for monitoring sleep apnea. The system comprises a respiration signal acquiring module, a processing module, a display module and an alarm module, wherein the respiration signal acquiring module comprises a thermistor, a signal amplifier module and a comparison module; the thermistor is used for acquiring a signal representing the flow of gas generated by the respiration of a patient and sending the signal to the signal amplifier module which is used for amplifying and sending the acquired respiration signal to the comparison module; the comparison module is used for comparing the respiration signal with a signal in a normal respiration range and sending the comparison signal to the processing module; and the processing module is used for processing the comparison signal, storing the processing information and sending a control signal to the display module and the alarm module. The system for monitoring the sleep apnea has the advantages of stable and reliable operation, safe use, high price performance ratio and capability for mass production and popularization.
