In this study, we proposed a cuff-less blood pressure measurement using a medical tape sensor with an embedded hetero-core optical fiber. The tape sensor pasted on the skin can directly detect pulse wave signals with a simple measuring device. Pulse transit time (PTT) was obtained from the time difference between the two pulse waveforms at the neck and foot. Systolic blood pressure (SBP) was estimated from PTT and the regression equation. The result shows that the maximum prediction error was 3.8 mmHg in five healthy young subjects. The SBP data were evaluated using a Bland-Altman method to assess the agreement of SBP data estimated by the proposed method with those measured by the cuff-based electronic sphygmomanometer. The mean ± 1.96 standard deviation of the estimated SBP against the reference was −1.3 ± 5.1 mmHg. The results show that the proposed noninvasive blood pressure measurement method can measure blood pressure, and its accuracy is comparable to that of the cuff-based electronic sphygmomanometer.

使用异芯光纤进行无袖血压估算

在这项研究中，我们提出了一种使用带有嵌入式异芯光纤的医用胶带传感器进行无袖血压测量的方法。粘贴在皮肤上的胶带传感器可以通过简单的测量装置直接检测脉搏波信号。脉搏传导时间（PTT）是根据颈部和足部两个脉搏波形之间的时间差获得的。收缩压 (SBP) 通过 PTT 和回归方程估算。结果显示，5 名健康年轻受试者的最大预测误差为 3.8 mmHg。使用 Bland-Altman 方法评估 SBP 数据，以评估所提出的方法估计的 SBP 数据与基于袖带的电子血压计测量的 SBP 数据的一致性。估计 SBP 相对于参考值的平均值 ± 1.96 标准偏差为 -1.3 ± 5.1 mmHg。结果表明，所提出的无创血压测量方法可以测量血压，其准确度与袖带式电子血压计相当。
