Problems solved by technology

[0008] However, the above-mentioned portable terminal can respond to the generation pattern "snoring sound → no breathing → snoring sound", but it is difficult for the portable terminal to respond to the generation pattern "snoring sound → no breathing → body movement" or the generation pattern "breathing sound → no breathing → body movement". " in response
Therefore, it is difficult for the portable terminal to determine the apnea state from the generation mode in which the portable terminal cannot respond

Abstract

A portable terminal(1) includes a breath determining unit(31) that, when having detected sounds having similar frequency components periodically in picked-up sounds by a microphone while an object person is being asleep, determines the sounds to be breath sounds. The terminal includes a snore determining unit(32) that, when the sound pressure of the breath sounds is greater than a first level threshold value, determines the sounds to be a snoring sound. The terminal includes a body motion determining unit(34) that determines whether a body motion is detected after the breath sounds are determined. The terminal further includes an apnea determining unit(33) that determines whether a silent interval is detected from a period of time between timings of the breath sound and the body motion when the body motion is detected and that determines the silent interval to be an apnea state when the silent interval is detected.

Description

technical field [0001] Embodiments discussed herein relate to an apnea determining device and an apnea determining method. Background technique [0002] In recent years, the number of patients suffering from sleep apnea syndrome and the number of people who will become potential sleep apnea syndrome patients tend to increase year by year. Sleep apnea syndrome is a disease that can be relieved by early treatment. Therefore, it is important for patients with sleep apnea, and those who would become potential sleep apnea patients, to be aware of sleep apnea. [0003] In recent years, for example, portable terminals having a function of detecting sleep apnea have been developed. The portable terminal records the subject's voice during sleep, and detects snoring from the recorded data. Then, when a silent interval is continuously detected between consecutive snoring sounds for a predetermined period of time, the portable terminal determines the silent interval as an apnea state...
