用於評估早產兒經口餵食狀態之無線多參數監測系統設計

Abstract

早產兒通常不能順利地完成經口餵食，而成熟的吸吮、吞嚥及呼吸活動是新生兒生存的關鍵指標，在現今的臨床狀況，醫護人員主要是用主觀的觀察來診斷嬰兒的吸吮、吞嚥及呼吸行為。由於早產兒本身較為脆弱多病和各種肌肉活動訊號的不明顯，現今依然缺乏一個經口餵食監測系統，能客觀地透過量化的生理參數來診斷嬰兒。在本研究中設計出一個無線多參數監測系統，可以在嬰兒進行經口餵食時監測吸吮、吞嚥及呼吸及心跳變異的量化信息。並由實驗結果證明該系統能有效的收取嬰兒的相關生理參數。而此系統將可提供未來在臨床上對嬰兒的經口能力進行客觀評價並監測與防護的工具。

Premature infants often cannot successfully and coordinately complete their oral feeding. Mature sucking, swallowing and respiration activities are crucial indicators for new born infant survival. In current clinical practices, care givers mainly depended on subjective behavioral observation of infants during oral feeding. There are lack of an integrated oral feeding monitoring systems to objectively and quantifiably monitor the related physiological parameters of infants. In this study, a wireless multi-parameter monitoring system for oral feeding of premature infants was proposed to monitor the sucking, swallowing, and breathing activities, and the information of heart rate variability quantitatively. The experimental results show that the proposed system can effectively detect the related physiological parameters of infants. Therefore, the proposed system may provide an objective clinical evaluation tool for oral feeding ability and safety of preterm infants in the future.
