摘　　要：我们设计能够用于呼吸机机械通气性能测试的人工模拟肺。首先,推导了人工模拟肺在理想情况下基于玻意耳定律的应用公式。然后,采用基于Lab VIEW的数据采集系统实现气体压强信号的采集,从而算出顺应性性能指标。给出了人工模拟肺模型及其数据采集系统。我们设计的人工模拟肺能够应用于呼吸机机械通气性能测试。To develop an artificial lung simulator for testing the performance of a mechanical ventilator. First,the applicable formula based upon the Boyle＇s law under the ideal case of the artificial lung simulator was derived. Then,the pressure inside the lung simulator was acquired by a data acquisition system based upon the Lab VIEW for computing the performance index,the compliance.The model and the data acquisition system were given. The artificial lung simulator designed can be used to test the performance of a mechanical ventilator.
