作者在本刊1979年第10期发表“输液自动定量真空灌注器介绍”一文后,接到很多同志来信,提出制作上的一些困难,主要是在注射器上要打出四个孔,还要同橡胶塞上的两孔相对应。这一点作者本人在实践中也有同感,为此进行了改革,现又研制成功一种只在针栓上打一个孔的输液自动定量真空灌注器,制作较为简便,经实际使用,效果较理想。一、结构:在距针栓上端5cm 处打一孔;针栓下部顶端通开,接一胶管与洗气瓶的进气管相联。洗气瓶的进气管与出气管之间的粗胶管中用实心胶塞隔开。粗胶管的下端接一玻管
The author published in the tenth issue of 1979, “infusion of automatic quantitative vacuum infusion device,” a text, received a lot of letters from comrades, made some difficulties in the production, mainly in the syringe to make four holes, but also Corresponds to the two holes on the rubber plug. This point the author I also agree in practice, to carry out the reform, and now successfully developed a hole in the needle plug only on a quantitative automatic infusion infusion device, the production is relatively simple, the actual use, the effect is more satisfactory. First, the structure: 5cm away from the top of the needle to play a hole at the top; open the top of the lower part of the needle, then a hose connected to the intake pipe of the gas bottle. Wash the gas cylinder with a thick rubber hose between the intake pipe and the outlet pipe separated by a solid rubber stopper. The bottom of the coarse hose connected to a glass tube
