Be applied to collection device of excrement and urine parasite worm ovum sample

Technical Field

The invention relates to the technical field of biological experimental equipment, in particular to a collecting device applied to a fecal parasite egg sample.

Background

The parasite egg inspection method commonly adopts saturated saline floating method and water washing precipitation method at present.

Principle of water washing precipitation method: the parasite eggs are heavier than water and can naturally sink to the bottom of the water. By using a natural sedimentation method, the eggs of the insects are concentrated on the water bottom for convenient inspection. The specific operation steps are as follows: placing 5-10 g of a feces sample in a container, adding a small amount of clear water to stir the feces sample into paste, adding clear water (about 20-30 times) into the paste, uniformly stirring and filtering the mixture, filtering the mixture (40-60 meshes), placing prepared feces liquid in the container, adding water into the container, standing the mixture for 20-30 minutes, pouring out supernatant (about 2/3), adding water, stirring the mixture, standing the mixture (the standing time can be relatively shortened but cannot be less than 5 minutes as the feces liquid becomes thinner gradually), repeatedly operating the operation until the liquid is transparent, pouring out the supernatant, leaving a small amount of water, and performing microscopic examination on the precipitate (the collected precipitate cannot be too concentrated, otherwise, the visual field is fuzzy during the microscopic examination). The method is mainly suitable for checking the schistosome eggs, echinoderm eggs and tapeworm segments, and is particularly suitable for the condition that the collection amount of the same excrement sample is large. But the detection rate of the eggs with smaller contrast is very low, such as nematodes, coccidian oocysts and the like.

For example, patent number is N201821772702.1 discloses a parasite egg collection device, includes the ovum collecting vessel, sieves a, sample, the ovum collecting vessel is one and has open-ended cylinder bucket, is provided with the collection portion of back taper in its bottom of the barrel, sieve the setting inside the staving of ovum collecting vessel, and with the barrel head face parallel arrangement of ovum collecting vessel, sample setting is in the perpendicular top department of sieving, and sample and the opening outer fringe fixed connection of ovum collecting vessel.
