一种血气分析仪及其使用方法A blood gas analyzer and method of use thereof

技术领域technical field

背景技术Background technique

现有国产血气分析仪的PCO2、PO2电极定标均采用气体配比不同的高气和低气两种压缩气体经过减压、保温、湿化后导入电极测量通道定标，其余电极采用标准液体定标。这种定标方式中，流路分气路和液路，气液交叉处控制较为复杂，特别是在出现故障的情况下，定标液或清洗液进入气路极易损坏电磁阀，另外，由于气瓶的存在，仪器不便于做成可移动使用的便携式或手推式，使得标准气运输不便；由于标准气体是压缩气体，气瓶又较大，不便于运输和使用，压缩气体要经过减压、保温、湿化后才可用，使用过程较为繁琐。因此急需一种使用方便，质量可靠的气血分析仪。The PCO2 and PO2 electrodes of existing domestic blood gas analyzers are calibrated using two compressed gases with different gas ratios, high gas and low gas, which are decompressed, kept warm, and humidified, and then introduced into the electrode measurement channel for calibration, and the rest of the electrodes use standard liquids target. In this calibration method, the flow path is divided into gas path and liquid path, and the control of the gas-liquid intersection is more complicated. Especially in the case of a failure, the calibration liquid or cleaning liquid enters the gas path and easily damages the solenoid valve. In addition, Due to the existence of gas cylinders, the instrument is not convenient to be portable or hand-push, which makes the standard gas transportation inconvenient; because the standard gas is compressed gas, and the gas cylinder is large, it is not easy to transport and use, and the compressed gas has to go through It can only be used after decompression, heat preservation, and humidification, and the use process is relatively cumbersome. Therefore be badly in need of a kind of easy to use, gas and blood analyzer of reliable quality.
