为提高工作效率，保证患者安全，根据产生负压－储存负压－使用负压的原理，研制了负压罐转盘式人工流产机，并投入临床，经三万余人次使用，结果表明该机在吸宫时间、减少术中出血量、防止人流综合征发生率等方面，均优于旧机，经显著性检验，Ｐ值均小于０．０１。
In order to improve work efficiency and ensure patient safety, a negative pressure tank rotary disc abortion machine was developed according to the principle of generating negative pressure - storage negative pressure - using negative pressure. The machine was put into clinical use and was used by more than 30,000 people. The results showed that the machine In the suction time, to reduce intraoperative bleeding, to prevent the incidence of flow syndrome and so on, are better than the old machine, the significance test, P values were less than 0.01.
