Outcome:

Data of Light-Contact Pulse Diagnostic Devices

Type:

Primary indicator

测量时间点:

受试者安静坐位休息3分钟后

测量方法:

(1)受试者安静坐位休息3分钟; (2)将轻接触式脉诊仪佩戴于双手桡动脉“寸、关、尺”部位; (3)连续采集脉搏信号120秒; (4)记录年龄、身高、体重、孕周及B超或hCG结果; (5)数据加密存储,仅用于科研分析。

Measure time point of outcome:

Following a 3-minute period of seated rest in a quiet environment.

Measure method:

(1) Participants remained seated at rest for 3 minutes. (2) A lightweight contact pulse diagnostic device was positioned over the "Cun, Guan, Chi" regions of the bilateral radial arteries. (3) Continuous pulse signals were acquired over a period of 120 seconds. (4) Demographic and clinical data—including age, height, weight, gestational age, and results from ultrasound or hCG testing—were documented. (5) All data were encrypted and stored exclusively for scientific research and analysis.
