摘要
根据人体工程学、手指的解剖结构和红外线透射原理研制了人体脉搏波光电传感器.其关键在于符合人体工程学的非接触式微功率光电传感器设计,使得人体组织尤其是穴位部分始终保持自然放松状态,确保测试结果不会因自身神经紧张和意外的外界条件变化而发生扭曲.该传感器使用了标准USB1.0接口,从而简化了电路设计.
A photoelectric sphygmograph sensor is developed using the infrared transmission theory. The shape of the sensor is in accordance with the anatomical structure of human fingers, The essential point of the design is that a low-power, untouched photoelectric sensor must to be fitted to the human factor engineering criterion so that the final results of the diagnosis will not be affected by the patient＇s tension. Moreover, the sensor supports the USB 1.0 protocol .
