摘要

本研究為建立一能即時量取血壓脈波之系統，此系統具有氣壓感測結合壓脈帶的高穩定性與操作方便等特性，而氣囊製作選用有拉伸彈力佳與抗老化等優點的矽橡膠為主要材料。此系統為三組感測器與氣囊能同步量取寸、關、尺三點之血壓脈波，撰寫程式用來量化波形轉折點等座標，計算出脈波特徵參數並提供給使用者分析。臨床應用以睡眠品質優劣者之脈波為主，受測者經由匹茲堡睡眠品質量表把分成兩組，分別為7位睡眠品質佳者及12位睡眠品質差者，透過t-test統計分析找出睡眠品質佳及睡眠品質差者之間的差異性。研究結果顯示，睡眠品質差者在脈波特徵參數會出現∠P1、∠P2及∠P明顯大於睡眠品質佳者，∠U明顯小於睡眠品質佳者，t1除關脈外皆明顯大於睡眠品質佳者，波形面積在寸沉、寸浮及關脈明顯小於睡眠品質佳者。本研究發現睡眠品質差者之脈相較之下會比較弦，血管阻力明顯增大，且於波形面積上發現寸關尺的臟腑存在著分侯學說，本研究的發現，相信會對中醫脈診的科學化有所助益。

The purpose of this study was to establish a real-time blood pressure wave measuring system. The system used an air pressure-sensing device which had three cuffs with high stability and user-friendly features. The airbag production was made of using silicone rubber as the main material. It had a good stretch and the advantage of anti-ageing. This system had three sets of the airbag and sensors. It could measure Cun, Guan, and Chi three parts of blood pressure pulse simultaneously. The program could record the quantitatively turning point of the waveform, and calculate pulse parameters. In the clinical applications, the sleep quality was tested nice or poor to compare with the pulse wave. Examinees were divided into 2 groups by Pittsburgh Sleep Quality Index (PSQI) that 7 adults with nice sleep quality and 12 adults with poor sleep quality. The t-test method was used to analyze the difference relationships between nice and poor sleep quality. The result of this research showed ∠P1, ∠P2, t1, and ∠P of the poor sleep quality adults were obviously larger than those of the nice sleep quality adults, but ∠U of the poor sleep quality adults were obviously smaller than that of the nice sleep quality adults. The curve area of the poor sleep quality adults was obviously smaller than that of the nice sleep quality adults in the Cun-deeping, Cun-floating, and Guan. Also, it was found that airbag production method could influence the measured wave results. In this research, we found the poor sleep quality adults tauter than the nice sleep quality adults and made the vascular resistance increase. We also found that Cun, Guan, Chi corresponded to different organs. The research results would be helpful for the scientific credentials of pulse diagnosis in Chinese medicine.
