Embodiment 1

[0018] 1. When installing the device, it is required that the upper edge of the water intake head (1) is slightly lower than the lake water surface, and the 50-80 mesh filter screen (2) can allow schistosome cercariae to enter and prevent large-sized impurities on the lake surface from entering.

[0019] 2. The lower opening of the water intake head (1) is connected to the inlet of the self-priming water pump (3) with a water pipe (15), and the water outlet of the self-priming water pump (3) is connected to the water inlet pipe (4) of the enrichment tank.

[0020] 3. According to the living habit of schistosomiasis cercariae on the water surface, the schistosomiasis cercariae will flow into the water intake head (1) together with the surface water, and be sent to the inner layer of the enrichment tank (5) through the self-priming pump (3). According to the principle of the connecting device, the water surface heights in the inner layer (5) of the enrichment tank and the outer l...

Abstract

The invention relates to an automatic collecting and real-time monitoring device for schistosoma cercaria, which is formed by a water carrier, a water suction pump, an enrichment pool, an observation pool and a digital microscopy, and has the working principles that: on the basis of the water surface life habit of the schistosoma cercaria and depending on the drive action of water flow, the schistosoma cercaria is gradually conveyed and enriched into an effective observation range of the digital microscopy in the observation pool, the schistosoma cercaria entering the observation pool can be on-line observed instantly through the digital microscopy, and the states of the schistosoma cercaria can be recorded. The automatic collecting and real-time monitoring device for the schistosoma cercaria can be used for monitoring and surveying schistosoma epidemics.

Description

technical field [0001] The invention belongs to the field of prevention and treatment of schistosomiasis, and relates to automatic enrichment and real-time monitoring of schistosomiasis cercariae, which can automatically enrich and monitor schistosomiasis cercariae on a large area of ​​water. Background technique [0002] The invasion of schistosomiasis cercariae into human skin and mucous membranes is the only way for people to be infected with schistosomiasis. Therefore, monitoring and killing the cercariae of Schistosoma japonicum is one of the key links in the work of schistosomiasis prevention. Since the cercariae of Schistosoma japonicum are only 280-360 μm×60-95 μm in size, they cannot be directly observed. At present, the method of manual fishing with sentinel rats, C-6 membranes, and nylon mesh bags is usually used for observation with a microscope. These methods have a long detection cycle, consume a lot of manpower and material resources, and cannot detect the ep...
