摘要
针对医院现有吸氧系统中金属浮球氧气流量计阀门手柄旋转角度和流量的对应关系,通过对手柄旋转角度进行编码,提出了一种基于单片机的医用智能氧气流量计的设计思想与实现方法,对病人吸氧时氧气流量和总吸氧量进行记录。实际应用表明,这种方法简单方便、安全可靠地解决了按吸氧量计费的问题。
A design ideology and realization method of the medical intelligent oxygen flowmeter based on a single chip computer are proposed,which performs the coding by the aid of the rotating angle of the nob on the valve of the metal ball cock oxygen flowmeter and aims at the corresponding relationship of the valve nob rotating angle and flow of the oxygen flowmeter available in hospitals.The flowmeter is used to record the patients oxygen flux and the total aspirate quantity.The system directly reads infrared data,which is produced by the metal ball cock oxygen flowmeter in the aspirate oxygen system available in hospitals The applicalion in practice indicates that the method is covenient and solves the problem of charge according to the quantity of the aspirate oxygen.
