聲、光、壓三通道脈搏訊號紀錄器

本論文以脈壓量測為主體的方式，將系統分為手腕量測系統以及手臂量測系統，並都在恆定的壓力下量測即時的脈搏訊號，同時以精簡的錄音系統以及紅外光光學檢測系統，同步擷取脈音訊號和光體積變化訊號，並以此整合三個即時的量測系統，深入分析心血管的生理參數。本研究即以三通道之聲、光、壓的同步訊號量測，進行實際的人體檢測及分析。研究中，本系統利用三通道擷取同步的生理訊號，得到以平均壓為基準的五段恆定壓力下所獲取的脈搏訊號、光體積變化訊號(PPG)和脈音訊號的變動，其中可由PPG訊號得到血管硬化指數(SI)，與血管反射指數(RI)，由脈搏訊號與PPG訊號結合，獲得脈波傳導速度(PWV)，而脈音變動訊號可以得到此段聲音之頻譜資料，由這些得到之即時參數，可藉由分析來對心血管生理狀況做進一步的評估。本研究依據量測系統擷取訊號後，得到各項參數的統計資料，可將本研究受測的兩個族群，依照年齡層的不同區分開來，並推論其得到的研究參數與心血管生理有對應關係之現象。本研究以整合的三通道訊號量測系統得到同時間的多個資訊參數，利用與以往不同的方式探討心血管方面的狀況，並得到相同的結果，得到嶄新的研究方向，在往後研究心血管生理狀況的分析上具有重大意義。

Pulse pressure measurement system is the main way of this study. The system is divided into the wrist measurement system and the arm measurement system, both measured real-time pulse signal base on constant pressure, at the same time used simplify recording system and infrared optic system, to retrieve the pulse acoustic signal and PPG signal synchronization. This study is to use a three-channel acoustic, photonics, pressure synchronized measurement system measure and analysis of subjects. This study used to capture three-channel synchronization of physiological signals, obtained pulse signal, PPG signal, pulse acoustic signal on the five segments of constant pressure that basis of average pressure. SI and RI can be obtained by the PPG signal, and PWV can be obtained by the PPG signal and pulse signal. In addition, used pulse acoustic changes to obtained spectrum information. Do further evaluation.by analysis these real-time parameters of the physical condition. The parameters of the statistical data be obtained in this study allows the subjects to distinguish between the two groups according to different ages. Inference that the correspondence between study parameters and cardiovascular physiology. In this study, the multi-information parameters at the same time and get the same results in different approaches. Validate of new feasibility cardiovascular indicator by integrating the three-channel signal measurement system. This also means that parameters in the analysis of the cardiovascular physiological conditions have great significance on the future study.
