【摘要】 在气流伯努利定理的基础上,设计和开发了基于ADuC7024的呼吸力学参数检测系统。介绍了该系统的传感器选型、放大电路设计、三通阀控制电路等硬件关键技术,同时对系统的应用程序和人机交互界面实现的功能也做了阐述。临床对比实验表明,该检测系统能有效监测病人呼吸气道的各项力学参数,实现对麻醉呼吸机工作状态的监测和病人呼吸气道的实时监测,对肺部疾病的家庭保健和预防起到很好的指导作用。更多还原

【Abstract】 a measuring system for respiratory mechanics parameters based on ADuC7024 is developed and designed,based on the Bernoulli’s theorem. This paper introduces some key problems like the sensor choosing,amplifier and valve control circuit designing,expatiates the application and man-machine interface. The clinical contrast results show that the measuring system could effectively monitor the patient’s respiratory mechanics parameters,could monitor work status of the ventilator and instruct the lung disease’s care and prevention.更多还原
