Abstract

In this study, we developed a system that can change position to improve obstructive sleep apnea. Blocking of the breathing airway caused by obstruction of the apnea, lateral position is provided by the airway to improve the apnea. We used a pressure sensor (FSR402) in the form of an array to determine the position of patient. The air cylinder was controlled to raise and lower the bed. As a result of calculating the pressure difference between the supine position and the lateral position, it was $0.41{\pm}0.30$ and $1.09{\pm}0.73$. In other words, when the patient is lateral position, the difference between the sensor values on the right and left side is large. Therefore, it is confirmed that the system can maintain airway to breath for improvement of obstructive sleep.

본 연구에서는 폐쇄성 수면 무호흡증을 개선하기 위하여 환자의 자세를 변환 시킬 수 있는 시스템을 구현하고자 한다. 폐쇄성 수면 무호흡증의 원인이 되는 기도 폐쇄는 수면 중 세로로 누운 자세로 변경 시켜 줄 경우 무호흡 증상을 완화 시켜 줄 수 있다. 이러한 자세 변환 시스템을 구현하기 위하여 어레이 형태의 FSR 402 압력센서를 사용하였고, 에어 실린더는 자세변환 시스템인 침대를 들어 올리는데 사용하였다. 본 연구에서 구현된 시스템을 이용하여 누운자세와 세로로 변경된 자세에서 압력센서 값의 차이를 계산하여 자세변환을 확인하였다. 그 결과 누운 자세에서 센서값이 차이는 $0.41{\pm}0.30$ 이고 세로로 자세를 변경하였을 때는 $1.09{\pm}0.73$로 나타났다. 즉, 자세를 변경하여 세로로 누운 자세에서는 센서값의 차이가 크게 나타났다. 그러므로 본 연구에서 제시한 폐쇄성수면 무호흡 환자의 자세변환시스템은 기도를 확보하여 무호흡 증상을 완화시켜 줄 수 있음을 확인하였다.
