摘要: | 摘要
設計製作一個可穿戴式的多參數心肺生理訊號量測系統,系統有很低的功率消耗(40mA,3.7V)、體積微小化(6×5cm2),應用震幅調變作短距無線化傳輸三組生理訊號,包含心電圖、呼吸、脈波傳輸頻帶依序為315、432、916MHz,再由個人數位助理(Personal Digital Assistant P.D.A)作生理訊號接收並應用內建的藍芽無線傳輸標準技術(2.4G)傳輸到其他端,傳輸到電腦端可再應用LabVIEW由網路通訊協定(TCPIP)建構出網路遠距量測平台,可以把量測到的三組心肺生理訊號傳輸到遠端電腦或伺服器上。微型化、無線化以及網路化,因此可穿戴式無線多參數心肺生理訊號網路遠距量測系統可以應用於高齡化社會居家照護、傳染病病患的隔離、需要長時間收集生理訊號的病患以及運動休閒的體適能評估。在穿戴式微系統製作上,生醫感測器的微型化設計相當重要,因此應用微機電製程所製作的微熱絲流量感測晶片來作呼吸功能量測,另一方面呼吸過程中氣體的含量分析,是一項心肺生理訊號的重要參數,因此初步也研製氧氣氣體感測晶片,使用表面電漿共振的原理來做氧氣氣體的感測。用光學式感測元件量測血液體積脈波的變化及運用電極片作第一導程的心電圖量測。量得心肺生理訊號藉由生醫訊號處理初步可以取得心跳、脈波、呼吸速率等參數來評估定量身體狀況。 Abstract A Multi Parameters Wearable Cardio-Pulmonary (CP) Physiological Signal Measurement system with features of low power consumptions (40 mA, 3.7 V), miniaturization (size 6×5 cm2) has been designed and fabricated. It is an amplitude shift keying (ASK) short range telemetric system that transmits three CP physiological signals including respiratory functions, electrocardiograph and pulse with frequency band of 315, 432, 916 MHz, respectively. Then we use a personal digital assistant (PDA) to receive the cardio-pulmonary physiological signals and transmit the digitized signals to a personal computer (PC) by bluetooth technology (2.4GHz). The PC can then communicate with a web server by LabVIEW software via TCP/IP protocol. A multi parameters wearable CP monitoring telemetric system has features of miniaturization, wireless and internet platform. The target application can be the evaluation of CP condition for homecare, patient in isolation and quarantine, long-term monitoring, and recreational sports. While fabricating the wearable micro system, it is very important to miniaturize biosensors. Consequently, we use a miniature bi-directional hot-wire sensor fabricated by microelectromechanical system technology for respiratory function, an optical sensor for s plethsymograph, and two surface electrodes for single lead electrocardiograph. In addition, the gas composition during respiration is a significant parameter in CP physiology. We design a novel oxygen gas sensor based on surface plasmon resonance (SPR). The parameters acquiring from this system has been used for the quantitative evaluation of heart rate, pulse rate and respiratory rate. |
