血氧是反映心肺功能和组织代谢状况的重要参数。血氧测试仪可应用于临床、卫生医学、基础医学及有关的科学研究。测定在一定时间范围内氧量方法,目前国内外均采用连续冲洗式的隔膜法。峰值电压在90％时需60秒左右,不能做到稳定、连续、快速反映实时值。特别采样过程中,抽血程序不可能保证存在漏氧,且价格昂贵,丹麦进口之ABL型仪器需要数万美金才能购置。本仪器成本费只需人民币3500元,如果批量生产,价格还可下降,可斟对我国国情广泛推广。由于采用
Oxygen is an important parameter that reflects cardiopulmonary function and tissue metabolic status. Blood oxygen tester can be used in clinical, health medicine, basic medicine and related scientific research. Determination of oxygen in a certain period of time methods, at home and abroad are using continuous flush diaphragm method. Peak voltage at 90% takes about 60 seconds, can not be stable, continuous, rapid reflection of real-time value. Special sampling process, the blood drawing process can not guarantee the existence of oxygen leakage, and expensive, the ABL-type instruments imported from Denmark need tens of thousands of dollars to buy. The cost of the instrument only RMB 3,500 yuan, if the mass production, the price can drop, we can pour on the extensive promotion of China’s national conditions. Due to adoption
