Human excrement incubated miracidia enrichment device

Abstract

The invention belongs to the technical field of schistosomiasis prevention and treatment, and discloses a human excrement incubated miracidia enrichment device. The enrichment device comprises a liquid suction graduated bottle, wherein the top of the liquid suction graduated bottle is in threaded connection with a graduated bottle upper cover, the top of the graduated bottle upper cover is fixedly communicated with a first hose and a second hose, the other end of the first hose is fixedly connected with a vacuum pump, the other end of the second hose is fixedly connected with a liquid suction top cover, and the bottom of the liquid suction top cover is in threaded connection with a bottom cover. According to the enrichment device, a conical flask is assembled with a bottom cover and a sealing pipe, then the second hose and the first hose are used for communicating the liquid suction graduated bottle with the bottom cover and communicating the liquid suction graduated bottle with the vacuum pump, the vacuum pump is started, gas in an upper cover of the graduated bottle is pumped out, the interior of the liquid suction graduated bottle is in a local vacuum state, local vacuum is transmitted into the bottom cover through the second hose, and a conical liquid suction head in the bottom cover adsorbs liquid and miracidia in the conical flask to an enrichment filter membrane together.

Description

technical field [0001] The invention belongs to the technical field of prevention and treatment of schistosomiasis, in particular to an enrichment device for miracidia hatched from human feces. Background technique [0002] Schistosomiasis japonicum is a zoonotic disease that seriously affects the health of infected people and brings significant social and economic impacts. The gold standard for the diagnosis of schistosomiasis is the detection of eggs or hatching of miracidia in the feces of infected people. The current epidemiological status of schistosomiasis is mainly based on low infection. It is difficult to find schistosomiasis eggs through the improved Kato thick smear method (41.7mg / piece) microscopic examination, and the hatching method (human feces 30g) can be extremely difficult due to the large amount of feces. Greatly improve the detection rate of schistosomiasis, while the fecal hatching method mainly uses the Erlenmeyer flask, and the hatched miracidia are ac...

Problems solved by technology

The current epidemiological status of schistosomiasis is mainly based on low infection. It is difficult to find schistosomiasis eggs through the improved Kato thick smear method (41.7mg / piece) microscopic examination, and the hatching method (human feces 30g) can be extremely difficult due to the large amount of feces. Greatly improve the detection rate of schistosomiasis, while the fecal hatching method mainly uses the Erlenmeyer flask, and the hatched miracidia are active in the neck of the Erlenmeyer flask. The inspection of the fecal hatching miracidia is performed on the neck of the Erlenmeyer flask with the naked eye or a magnifying glass, depending on the individual According to experience, due to the influence of factors such as the refraction of the glass Erlenmeyer flask, the turbidity of the hatching feces, the small number of miracidia or the poor vitality, it is easy to cause missed and false detections, which affects the diagnosis and control of schistosomiasis.
