Device for extracting parasitic ovum in feces

The utility model relates to the technical field of medical laboratory equipment, and provides a device for extracting parasitic ovum in feces. The device for extracting the parasitic ovum in the feces comprises a sampling bottle, a bottle cover, a mixing cylinder, a filter cylinder and a water supply device, wherein the bottle cover is connected with a sampling spoon, the bottle cover and the sampling bottle are connected through a thread, a thread which is matched with the bottle cover is also arranged on the top end of the mixing cylinder, a water inlet is arranged on the side surface of the mixing cylinder, the water outlet direction of the water inlet is aimed to the sampling spoon which is arranged on the bottle cover, the water supply device is communicated with the water inlet, the lower portion of the mixing cylinder is of a circular shape, a first filter screen which does not allow crude fiber particles in the feces to pass through is fixed on the lowest position of the circular shape, the filter cylinder is detachably connected with the bottom end of the mixing cylinder, and a second filter screen which does not allow the parasitic ovum to pass through is arranged on the bottom end of the filter cylinder. The water supply device in the device for extracting the parasitic ovum in the feces injects water flow into the mixing cylinder from the water inlet to wash the sampling spoon, thereby completing transfer of the feces, also cleaning the sampling spoon preliminarily, further playing the mixing effect, and being healthful and convenient to use.
