Abstract: With the increasing demand of people for health and medical services, auxiliary pulse diagnostic equipment has the advantages of remote diagnosis, real-time monitoring, convenient self-help, high efficiency and so on, and is increasingly favored by consumers. Currently, pulse diagnostic equipment, such as intelligent pulse monitoring system and dynamic pulse waveform analyzer, has high requirements for environmental conditions, low sensitivity and slightly cumbersome operation. Therefore, the equipment with smaller volume, more convenience, stable performance, simple operation and data visualization has attracted the attention of a wide range of researchers. Our team has developed gloves for collecting pulse information of traditional Chinese medicine. The device can fit perfectly with the skin and has good collection performance.
This paper discusses the functional structure design and implementation of pulse collection gloves, including device preparation, structure design, system construction, operation test and so on. The carbon fiber dimension material independently developed by our team is used in the sensing material in the pulse collection gloves. Two carbon fibers are used as a cross structure and are fixed on the flexible printed board through copper holes, which is used as a single sensing unit. The flexible sensor is placed at the fingertips of the index finger, middle finger and ring finger of the glove. It can not only read the key pulse information of the human body such as Cun, Guan and Chi, but also accurately identify the pulse information of the wrist and neck. The copper wire in the mezzanine channel is used as the transmission line to connect with the sensing unit, and the pulse information is transmitted to the circuit acquisition module on the back of the hand. The pulse information data are processed here and sent to mobile phones, computer terminals and uploaded to the cloud database.
The structural highlight of the pulse collection glove is the sandwich design on the back. When the glove works, with the bending and straightening of the fingers, the transmission line carried by the glove is frequently in a tight and relaxed state. The design of the glove mezzanine channel can realize the relatively loose state of the transmission line all the time, avoid the phenomenon that the transmission line is easy to be stretched and broken during use, and it fits well with the skin, ensuring the stable transmission of pulse diagnosis data.
The pulse diagnosis collection gloves can assist users to digitize and standardize pulse information, provide more stable and rich data tips and references for clinical diagnosis of traditional Chinese medicine, and provide more possibilities for home self-help pulse diagnosis and cloud diagnosis.

摘要： 针对当前中医脉诊设备体积庞大、操作环境条件要求较高、灵敏度较低以及操作繁琐等问题，开发了一款基于柔性传感技术的脉诊信息采集手套。该手套的柔性传感器由十字交叉的碳纤维构成传感单元，分别分布在手套食指、中指、无名指指尖位置；以铜线为传导线，通过手指设计的夹层通道与传感单元连接，将脉诊信息传输至手背的电路板模块；信息数据通过电路板处理后发送至手机、计算机终端，并上传至云数据库。测试结果表明：在0~0.2 N脉压力范围内，传感器表现出超高的灵敏度（201.305 N-1），能有效识别微弱的脉冲信号；传感器的响应时间和恢复时间均为82 ms，能够实时监测压力信号的变化；在2.0 N的外力作用下，经过1000次循环测试，该传感器前后电阻变化率基本保持不变，表明该传感器具有长期稳定性的特性。该装置可以将脉诊信息数字化、规范化，可为中医临床诊断提供更稳定、丰富的数据提示及参考，也为居家自助诊脉以及云端诊病提供更多可能性。
