摘要
该文主要探究自动调压无创呼吸机软件部分的设计方法,并开展测试观察应用效果。呼吸机采用μc/OS-II实时嵌入式操作系统,呼吸机与上位机之间使用USB接口实现通信。用户佩戴呼吸机面罩后,传感器实时采集压力数据,并根据用户的呼吸动作自动调节输出压力,在呼气时降低压力以减小呼气阻力,在吸气时增加压力以辅助吸气。从测试情况来看,该文设计的自动调压无创呼吸机基本上达到设计要求。
This paper mainly explores the design method of the software part of the automatic pressure regulating non-invasive ventilator,and carries out the test to observe the application effect.The ventilator adoptsμc/OS-II real-time embedded operating system,and the USB interface is used to realize the communication between the ventilator and the host computer.After the user wears a ventilator mask,the sensor collects the pressure data in real time,automatically adjusts the output pressure according to the user's breathing action,reduces the pressure when exhaling to reduce expiratory resistance,and increases the pressure when inhaling to assist inhalation.Seen from the angle of the test,the automatic pressure regulating non-invasive ventilator designed in this paper basically meets the design requirements.
