摘要
设计了一种可调节模拟肺,通过模拟呼吸系统气道阻力和肺顺应性(肺硬度)的变化及漏气(漏气损失),产生阻塞性通气障碍或限制性通气障碍的病理状态效果,与呼吸机连接后,临床医生通过观察呼吸机运行状态变化,调节各项机械通气参数,进而掌握呼吸机工作原理和性能。
Abstract We designed an adjustable simulated lung for clinical use. Depending on the feature of adjustable resistance and compliance, the device could simulate various pathological changes of lung, such as obstructive diseases and restrictive diseases. Thru simulating various pathological conditions with the device, the clinicians could learn how to manipulate a mechanical ventilator. In addition, the device has a leakage equipment for simulating leakage of respiratory circuit, depending on which the clinicians could learn more about ventilators.
