光闸式桡动脉搏传感器的研制

RESEARCH FOR THE PULSE WAVE SENSOR MADE UP OF OPTICAL FLOODGATE

本文介绍一种自行设计的新型脉搏传感器。这种传感器让脉搏波在寸口处的搏动推动一光闸系统。然后通过光电转换可直接在通用示波器上显示出脉图信号。文中还详细介绍了该传感器研制过程中的性能测试，从测度结果看，该传感器具有灵敏度高，线性好等特点，可广泛应用于临床和科研。

In this paper,We reported a new type of pulse wave sensor.In this sensor an optical floodgate sys-tem is pushed up and down by pulsation of pulse,Then,The pulsation information is shown on screen of oscillo-graph by photoelectric conversion,We also introduced to the method testing the sensor characterization.In re-sult,The sensor has advantages such as high sensitivity,wide linearity and small size.
