一、引言随着我国医疗卫生事业迅速的发展,许多医院正在建设或改扩建医疗用房。在医院建设中,医用氧气系统因与生命直接相关而被称为“生命支持系统”。医院医用氧气系统由气源部分、管道输送部分和末端装置等三部分组成。地区和城市中心医院病人多,对氧气的需求量大,依赖性强,因此,医用气体系统供应的可靠性应从气源上保证。目前,国内的气源有高压气瓶、液氧罐和变压吸附式制氧机制氧等三种。合理选用氧气气源,增加医院氧气使用的可靠性,不仅十分重要,而且对医院的节约降耗起到关键作用。
I. INTRODUCTION With the rapid development of medical and health undertaking in our country, many hospitals are building or rebuilding medical buildings. In hospital construction, the medical oxygen system is called the “life support system” because it is directly related to life. The hospital medical oxygen system is composed of gas source part, pipeline conveying part and end device. There are many patients in hospitals in district and city center, and the demand for oxygen is large and dependent. Therefore, the reliability of supply of medical gas system should be guaranteed from gas source. At present, there are three kinds of gas sources: high pressure gas cylinder, liquid oxygen tank and oxygen pressure swing adsorption oxygen plant. Rational use of oxygen gas source, increasing the reliability of hospital oxygen use, not only is very important, but also plays a key role in saving the hospital.
