一种战场士兵多生命体征监测头带设计

摘要

针对战场环境，从便携式角度出发，采用可穿戴技术，设计了一种集成心电、脑电、脉搏波、体温以及人体姿态测量的战场士兵多生命体征监测头带。其中，以超低功耗的MSP430单片机为主控芯片，以低功耗的ADS1292R作为双电极心电和脑电采集芯片，以反射式光频转换器采集人体光电容积脉搏波，以医疗专用负温度系数（ NTC）热敏电阻器作为体温传感器，以MMA7660数字三轴加速度计作为姿态测量传感器。通过蓝牙将所采集信息传送至单兵PDA，实现了多生命体征的监测，具备体积小、重量轻、功耗低、成本低、便携舒适等特点。%A monitoring headband which can measure electrocardiogram( ECG),electroencephalogram( EEG), photoplethysmography( PPG),body temperature and human posture is designed to monitor multiple vital signs of the soldiers in battlefield environment. Ultra-low-power consumption microcontroller MSP430 is used as main controller chip,low-power consumption ADS1292R is used as main collection chip for ECG and EEG,a reflex optical-to-frequency converter is used for collection of PPG,a medical negative temperature coefficient( NTC ) resistor is used as body temperature sensor,digital 3-axis accelerometer MMA7660 is used as attitude measurement sensor. Collected information is transmitted to personal digital assistant( PDA)through Gluetooth,realize multiple vital signs monitoring and it has features such as small size,light weight,low-power consumption,low-cost,portable and comfortable.
