1.静脉输液简介目前采用的输液方式多为需要进气管路的半开放输液.这种静脉输液是利用液体静压与大气压的物理原理,使液体输入到人体静脉内的.输液装置中的输液瓶是一个入口和大气相通,下连橡胶管的玻璃瓶(塑料软袋或更为先进的完全符合环保的复合膜软袋).正常情况下输液时,应将输液瓶挂于距穿刺部位约50～60cm高度处.瓶内液体在大气压力的作用下,使药液滴入
1. INTRODUCTION OF INTRAVENOUS INFUSION At present, the most commonly used infusion methods are semi-open infusions that require an intake line. This type of intravenous infusion is based on the physical principle of hydrostatic pressure and atmospheric pressure, allowing fluids to be introduced into the human vein. Infusion infusion devices The bottle is an entrance and the atmosphere, the lower glass bottle with rubber tube (plastic soft bag or more advanced fully-integrated membrane soft bag). In normal circumstances, the infusion bottle should be hung from the puncture site about At a height of 50-60cm, the liquid in the bottle is dropped into the liquid under the effect of atmospheric pressure.
