<P>PROBLEM TO BE SOLVED: To provide a hypopnea detector that can easily detect an infrequent respiration state during sleep. <P>SOLUTION: The hypopnea detector includes: a vibration sensor 1 generating an electric charge by detecting body movement of a sleeping person 20; a charge amplifier part 2 converting the generated electric charge in the vibration sensor 1 into a voltage signal; a body movement detection part 3 detecting the body movement based on the voltage signal; a first filter part 4 extracting a snore component of the sleeping person 20 from the voltage signal; a snore detecting part 5 detecting snore based on the extracted snore component; a second filter part 6 extracting a respiratory component of the sleeping person 20 from the voltage signal; an abnormality detection part 7 determining whether a respiration fluctuation is abnormal based on the extracted respiratory component; an infrequent respiration detecting part 8 determining the infrequent respiration state when the body movement is not detected by the body movement detection part 3, the snore is not detected by the snore detecting part 5 and the respiration fluctuation is determined to be abnormal by the abnormality detection part 7; and a display part 9 displaying the generation of the infrequent respiration state when the infrequent respiration state is determined by the infrequent respiration detecting part 8. <P>COPYRIGHT: (C)2012,JPO&INPIT |
