粪便检查仍是当前诊断血吸虫病的主要方法。随着血防形势的发展,血吸虫病感染率与感染度逐年下降,运用常规的沉淀孵化(镜检)方法,虫卵检出率往往较低,而且,该法还存在操作过繁、时间过长、每次检查的粪量少、操作过程中散失虫卵较多等缺点。为了适应查病需要,天门县血防战线参考外地尼龙袋集卵法的经验,经过反复实践,初步试制了粪便荡洗机,提高了检出率,并能克服常规沉孵法的缺点。据此,我们于1977年8月在该县净潭公社、八 Stool examination is still the main method of diagnosis of schistosomiasis. With the development of blood-borne anti-infection situation, the infection rate and infection rate of schistosomiasis declines year by year. The detection rate of eggs is often low by the conventional method of sediment incubation (microscopic examination). Moreover, , Each fecal inspection less, the operation lost more eggs and other shortcomings. In order to adapt to the need of checking the disease, Tianmen County Blood-Defense Frontline made reference to the experiences of foreign nylon bag-laying method. Through repeated practice, the preliminary trial of the manure-washing machine improved the detection rate and overcome the shortcomings of the conventional method. Accordingly, we in August 1977 in the county net Tan commune, eight
