随着现代电子技术和生物工程学的飞速发展,肺功能仪不断推陈出新。选用肺功能仪,主要从3个方面进行考虑:一是仪器的适用性,是指适合医院自身情况、能真正用于开展业务的仪器。二是仪器的性价比,是指性能优越、计量准确,且价格合理的仪器。三是售后服务与技术支持,是指故障率低且维修服务及时的仪器。肺功能仪的日常维护是仪器可靠性的保障,其中流速/容量校准、检测气体浓度校准等日常仪器校准是重要内容,当仪器已使用多年或疑有测量误差过大时,建议采用标准呼吸模拟器进行质量检测。
With the rapid development of modern electronic technology and bioengineering, the continuous development of the lung function instrument. The choice of lung function instrument, mainly from three aspects to consider: First, the applicability of the instrument refers to the hospital’s own situation, can really be used to carry out business equipment. Second, the cost of the instrument, refers to superior performance, accurate measurement, and the price is reasonable instruments. Third, after-sales service and technical support, refers to the low failure rate and timely maintenance of equipment. Routine maintenance of the lung function instrument is the guarantee of the reliability of the instrument. The daily instrument calibration such as flow rate / volume calibration and gas concentration calibration is an important content. When the instrument has been used for many years or the measurement error is too large, it is recommended to adopt the standard breath simulation For quality testing.
