呼吸机是医院常备的抢救设备,为呼吸功能不全的病人提供呼吸支持增强其新陈代谢。为了进一步推动呼吸机发展,需要建立呼吸机测试平台。本文提出了基于虚拟仪器技术的呼吸机测试方法。利用采集卡、传感器、模拟肺、LabVIEW配合C语言编程实现仪器。最后测试Servoi呼吸机。测试结果表明,呼吸机测试虚拟仪器与VT-Plus具有等效果的性能,完全满足实际测试需求。 Ventilator is the hospital’s standing rescue equipment to provide respiratory support for patients with respiratory insufficiency to enhance their metabolism. In order to further promote the development of ventilator, need to establish a ventilator test platform. This paper presents a ventilator test method based on virtual instrument technology. The use of acquisition cards, sensors, lung simulation, LabVIEW with C language programming instrument. Finally test the Servoi ventilator. The test results show that the ventilator test virtual instrument and VT-Plus have equivalent performance, fully meet the actual test needs.
