Abstract

嚥下は一般的に口腔期,咽頭期,食道期の3期に分類される。今回ストローを用いて吸啜,嚥下する際の口腔期,咽頭期について研究した。ファイバースコープ,超音波断層法,圧センサーを用いて行った。対象は健康な成人男子2名で,これらの結果を同時記録した。すべての器機にキャリブレイションを行い,予備実験としてphonation/ka/,long/S/発話,吸気,呼気,ハミングを行った。結果:吸啜開始時,舌と軟口蓋が接触し,その後離開した。ファイバースコープや口腔,咽頭圧センサーでも同様の所見を認めた。今後更なる研究が望まれる。

In general, the swallowing mechanism has been divided into three phases: the oral, the pharyngeal and the esophageal. This study was designed to study the minute mechanism of the transitional movements between the oral and the pharyngeal phase during sucking and swallowing through a fine tube. A flexible fiber scope, ultrasonograph and pressure transducers were used. Subjects were two healthy males. Multi-modal data were recorded simultaneously. Making sure that the equipment was functioning and calibrated properly, trial studies were done, such as the phonation of /ka/ sounds, long /S/ sounds, humming and inspiration and expiration before and after the data acquisition. Results were as follows. In the case of sipping juice, the tongue and the soft palate touched just at the beginning of sucking. After that, the tongue and the soft palate were separated. These findings were observed both in the ultrasound image and in the intraoral and pharyngeal pressure analyses. Further studies with more subjects are required for confirmation.
