我科在近几年来已将冷冻技术逐渐应用于临床,为了探讨在临床应用中发现和提出的一些问题,因此我们利用家兔及离体猪肌肉作液氮冷冻动物试验,现将临床的初步资料报告于后,供参考。冷冻工具是采用我科自制简便液氮“冷刀”(73—Ⅱ),输液管横段外径为1.8mm,室温18℃,每分钟喷液量为10～11克。(“冷刀”结构及喷液测定见新医学第6期281页,1974) In recent years, our department has been frozen technology gradually applied to clinical, in order to explore some of the problems found in clinical applications and put forward, so we use rabbit and pig muscle fluid frozen animal experiments, now the clinical preliminary Information report later, for reference. The freezing tool is made of our own simple liquid nitrogen “cold knife” (73-Ⅱ), the outer diameter of the cross-section of the infusion tube is 1.8mm, room temperature 18 ℃, the volume of liquid injection per minute is 10 ~ 11g.
