前几年,我所曾试制过一种液氮输液管,后因某单位对输液管的专门需要,我所就在原基础上进行了改进设计,经过不断努力,终于设计制成体积小、重量轻、使用方便、装置完整的自动低温输液器,它不用外加任何能源和辅助设备,只要将它插入杜瓦容器内,便能自动或者加速输送低温液体,如图所示。该输液器是利用两根不锈钢管子和三只单向阀的虹吸作用,一个
A few years ago, I had tried a liquid nitrogen infusion tube, after a unit due to the special needs of the infusion tube, I was on the basis of the original design improvements, after continuous efforts, and finally designed into a small size, weight Light, easy-to-use, fully-equipped, automated cryogenic transfusion unit that dispenses any energy and ancillary equipment as long as it is inserted into a Dewar vessel to deliver cryogenic liquid automatically or at an accelerated rate, as shown. The infusion set is a siphon effect using two stainless steel tubes and three one-way valves
