呼吸机通气性能自动化测试系统研究和设计

Research and Design of Automatic Test System for Ventilator Performance

呼吸机是一种能替代自主通气功能的重要医疗器械,其安全可靠关系到患者的健康甚至生命安全。随着呼吸设备国内外新版标准的发布,对检测和评价提出了更高的要求。该文重点介绍了一款呼吸机通气性能自动化测试系统。该测试系统基于Imtmedical公司PF-300气流分析仪和标准模拟肺,开发了模拟肺自动切换模块,并使用基于Python的软件开发平台实现了呼吸机自动化测试系统的设计。不仅能自动测试呼吸机的所有通气控制参数和监测参数,还能实现自动数据记录,形成报告和数据分析,提升了检验检测和质控的效率及质量。

Ventilator is an important medical instrument which can replace the function of autonomous ventilation artificially.Its safety and reliability are related to the health and even life safety of patients.With the publishing of the new national standard and international standard for ventilators,higher requirements are put forward for the detection and evaluation.This study mainly introduces an automatic test system for ventilator performance.The test system is based on PF-300 air-flow analyzer of Imtmedical and standard simulation lung.The automatic switch module of simulation lung is developed,and the automatic test system of ventilator is designed using the software development platform based on Python.It can not only automatically test all ventilation control parameters and monitoring parameters of the ventilator,but also realize automatic data recording,form reports and data analysis,and improve the efficiency and quality of inspection,detection and quality control.
