900系统呼吸机在国内已普遍使用。除了操作和使用不当造成故障以外,仪器系统的技术故障也会造成工作失常,本文就此作些分析。 一、呼出流量指示表明显偏大 首先应检查呼出流量传感器的过滤网是否太脏,因此而造成呼出气流受阻,将使通过放置应变电阻的小孔中的分流气流量大增,造成指示偏大。解决的办法是清洗或更换滤网。传感器的定期清洁,对流量指示以及呼吸机的正常工作是十分重要的。
The 900 system ventilator has been widely used in the country. In addition to the malfunctions caused by improper operation and use, technical malfunctions of the instrument system can also cause malfunctions. This article makes some analysis. First, the apparent flow of the exhalation flow indication table should first check whether the filter of the exhalation flow sensor is too dirty, thus causing obstruction of the exhalation air flow, which will increase the flow of the divergent air in the small hole through the placement of the strain resistance, resulting in an indication of large . The solution is to clean or replace the filter. The regular cleaning of the sensor is very important for the flow indication and the normal operation of the ventilator.
