一种新型生命体征信号采集设备的研制

Development of a novel vital signs acquisition device

介绍一种新型的生命体征信号采集设备,该设备由传感单元和软件组成。使用时将传感单元放置于卧床枕头正下方,以收集人体睡眠时的体震信号,并通过无线方式传输至软件进行存储和分析,从而实现对心率和呼吸率两种生命体征的长期连续监测。通过使用人工测算、已上市的监护产品及本设备采集8位受试者的心率和呼吸率指标,初步验证该设备的监测指标有一定的准确性。

A new vital signs signal acquisition device which is composed of sensing unit and software is introduced in this paper.The sensing unit is placed in the bed under the pillow to collect human body vibration signals during sleep. Through the wireless transmission, the vibration signals are transmitted to the software for storage and analysis, achieving the long-term continuous monitoring for the two vital signs（heart rate and respiratory rate）. The heart rate and respiration rate of 8 subjects collected by artificial estimation, marketed monitoring products, and the new vital signs signal acquisition device, separately, are compared.The comparison shows that the introduced vital signs signal acquisition device had satisfactory accuracy.
