一、引言尿中雌激素的含量,是用于妇产科临床诊断卵巢功能,胎儿胎盘功能,以及用于计划生育的药物研究和有关的生殖生理的理论研究中的一个重要指标。而尿中雌激素的提取,多年来一直是用分液漏斗进行手工操作的,工作效率低。我们参考文献[1],并结合实验室操作的经验,试制成雌激素提取机。经三年2千多小时应用,证明该提取机性能良 First, the introduction of urinary estrogen levels, is used in obstetrics and gynecology clinical diagnosis of ovarian function, fetal placental function, as well as for the study of family planning drugs and related reproductive physiology in an important indicator of theoretical research. The urinary estrogen extraction, over the years has been using a separatory funnel for manual operation, low efficiency. We reference [1], and combined with the experience of laboratory operations, trial production of estrogen extraction machine. After three years more than two thousand hours of application, to prove that the extractor good performance
