초록
본 연구에서는 코골이 방지 베개의 효율성을 검증하기 위해 수면다원검사 측정 결과를 이용한 분석 방법 및 총 수면 시간과 코골이 시간 등의 효율성 평가에 유용한 변수를 제안하는 것으로 연구가 진행되었다. 사용된 코골이 방지 베개는 두 개의 polyvinylidene fluoride (PVDF) 진동 센서와 펌프, 밸브, 공기주머니로 구성되어있다. 두 진동센서를 통해 코골이 신호를 정확하게 검출하고, 코골이 판정 시 제시된 알고리즘에 따라 베개 내부에 부착된 공기 주머니를 팽창시켜 목을 들어줌으로써 좁아진 기도를 확보하게 해 코골이를 경감시키도록 베개가 설계되었다. 베개의 유효성을 검증하기 위해 수면다원검사를 실시하였고, 실험에는 두 명의 피실험자가 참여하였으며 코골이 베개의 사용 유무에 따라 실험이 진행되었다. 수면다원검사로부터 다양한 변수 값을 측정하여 분석하였고, 이 결과 값들로부터 베개의 유효성을 판단하였다. 두 피실험자 모두 총 수면시간은 큰 차이를 보이지 않았으며 총 코골이 시간과 가장 긴 코골이 시간은 감소하는 것을 확인하였고 코골이 방지 베개가 코골이를 효율적으로 경감하도록 하는 것을 알 수 있었다. 본 연구의 결과로부터 수면다원검사를 통해 코골이 방지 베개의 유효성을 확인하였으며 측정된 각 변수들과 수면의 질과의 관계를 살펴봄으로써 향후 많은 연구에 활용될 것이다.
Abstract
In this study, the parameters of Polysomnography (PSG) test, such as total sleep time, snoring time, had been analyzed to evaluate the effectiveness of a developed anti-snore pillow. The developed anti-snore pillow is made up of two polyvinylidene fluoride (PVDF) vibration sensors, pumps, valves, and air bladders. The two PVDF sensors inside the pillow can acquire the sound signals and the algorithm was perfectly designed to extract snoring by removing unwanted noise accurately and automatically. Once the pillow recognizes snore, a pump inside the hardware activates, and a bladder under the neck area inside the pillow will be inflated. The PSG test was used and two volunteers were participated for the study. The parameters of the PSG results were analyzed to evaluate the effectiveness of the anti-snore pillow. The total sleep time of each volunteer was similar on each phase of test, but the snoring time and the longest snoring episode were significantly decreased with the use of anti-snore pillow. The overall results showed excellent possibilities for reducing snoring for the person who snores during sleep by using the anti-snore pillow. The effectiveness of the anti-snore pillow can be evaluated by the PSG test. Moreover, the relationship between each parameter of PSG test and the quality of sleep will be used for further researches.
