SLEEP APNEA SYNDROME TESTING APPARATUS, TEST METHOD FOR SLEEP APNEA SYNDROME AND TANGIBLE RECORDING MEDIUM RECORDING PROGRAM
First Claim
1. A sleep apnea syndrome testing apparatus comprising:
- an analyzing unit to analyze a sound signal resulting from a subject during sleep and collected by a sound pickup device and to calculate duration and frequency characteristics of a partial sound signal being a sound produced by the subject and being included in the sound signal; and
a determining unit to determine, based on an analysis result by the analyzing unit, whether or not the duration and the frequency characteristics of the partial sound signal match the characteristic sound and to determine whether or not the sound signal includes a characteristic sound produced when a sleep state of the subject recovers from an apneic state into a breathing state.

Abstract
A sleep apnea syndrome testing apparatus includes: an analyzing unit that analyzes every unit time a sound signal resulting from a subject during sleep; a determining unit that determines whether a unit time of the sound signal includes a breath sound or a characteristic sound produced when a patient with sleep apnea syndrome recovers from an apneic state into a breathing state, and the determining unit that determines that the sleep state of the subject in the unit time is any one of “breathing restored state,” “state with breathing,” and “state without breathing;” a storage unit in which a sleep state of the subject in each unit time is stored; and a detecting unit that detects an apneic state of the subject if a history of the sleep states of the subject indicates at least a transition from the “state without breathing” to the “breathing restored state.”

10. A test method for sleep apnea syndrome by a computer, comprising
analyzing a sound signal produced during sleep and collected by a sound pickup device and calculating duration and frequency characteristics of a partial sound signal being a sound produced by the subject and being included in the sound signal, and determining based on an analysis result whether or not the duration and the frequency characteristics of the partial sound signal match the characteristic sound and determining result by the analyzing unit whether or not the sound signal includes a characteristic sound produced when a state recovers from an apneic state into a breathing state.

11. A program for causing a computer operating as a sleep apnea syndrome testing apparatus to execute:
-
analyzing a sound signal produced during sleep and collected by a sound pickup device and calculating duration and frequency characteristics of a partial sound signal being a sound produced by the subject and being included in the sound signal; and determining based on an analysis result whether or not the duration and the frequency characteristics of the partial sound signal match the characteristic sound and determining whether or not the sound signal includes a characteristic sound produced when a state recovers from an apneic state into a breathing state.
