心电监护服装结构对监测点位移的影响研究

Research of Effects of ECG Monitoring Clothing Structure on Displacement of Monitoring Points

心电信号的实时监护可以达到人体慢性心血管疾病提前预防的目的。服装与人体之间的近身关系及其优良的舒适性与移动性能使得其成为心电实时监护设备的最佳载体,可以长期连续获取丰富的人体生理信息。通过研究心电监护服装结构对心电采集稳定性能的影响,旨在找出造成电极从穿着者原始点位置偏移较小的服装结构,达到准确监测人体生理参数的目的。设计了三款心电监护服装,采用在服装上集成位移传感器的方法,研究动态穿着条件下服装结构对电极偏移的影响。试验结果表明:服装结构对心电监测点的稳定性有很大的影响,不同的服装结构对监测点的作用力不同,因此位移也有很大的差异。三款服装中造成监测点位移相对较小的服装结构是款式1,该款式能够有效地平衡监测点的位置。

Real-time monitoring of ECG signal can prevent chronic cardiovascular diseases in early stage. The special relationship between clothing and human body, and the excellent comfort and mobility performance make clothing become the best carrier for the ECG real-time monitoring equipment which can obtain continuous long-term human physiological information. This paper studies the influence of ECG monitoring clothing structure on ECG collection stability and aims to find out the clothing structure that causes the smaller deviation from the original point and reach the purpose of accurately monitoring physiological parameters of human body. Three types of ECG monitoring clothing are designed. The method of integrating displacement sensor on the clothing is used to study the influence of clothing structure on electrode displacement in the dynamic condition. The result shows that the structure of ECG clothing has a great influence on the stability of the monitoring point. Furthermore, different clothing structures have different force on the monitoring points, so there are big differences in displacement. Style 1 relatively causes the smallest displacement among the three types of clothing. This style can effectively balance positions of monitoring points.
