Three-cavity communication type sampling and filtering device and water-through filtering type sampling process thereof

Abstract

The invention relates to a three-cavity communication type sampling and filtering device and a water-through filtering type sampling process thereof. The three-cavity communication type sampling and filtering device comprises a base, wherein a three-cavity filtering type detection cup is arranged on the left side of the base; a vertically upward upright post is arranged on the right side of the base; a hollow liquid inlet stirring and sampling device is positioned above the three-cavity filtering type detection cup and movably connected with the upright post. The water-through filtering type sampling process comprises the following steps: performing primary filtration on a to-be-detected sample solution via a first filtering net, and performing secondary filtration on the sample solution by virtue of a second filtering net on an arc-shaped plate; pumping out the sample solution filtered twice from a third cavity. According to the three-cavity communicated sampling and filtering deviceand the water-through filtering type sampling process thereof disclosed by the invention, the problems that the conventional sampling device is easily contaminated by impurities, shooting is not clearand counting is inaccurate can be solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a three-cavity connected sampling and filtering device and a water-through-filtering sampling process thereof. Background technique [0002] With the development of science and technology, the medical industry is also growing, and the requirements for medical equipment are becoming more and more stringent. The detection of patient excrement is one of the basic means to find the cause of the disease, and it is also a key step in prescribing the right medicine. Sampling devices are required during the testing process. However, the existing sampling devices generally use open sampling cups or simple sampling bottles, which have disadvantages such as too simple structure, single function, inability to automatically remove impurities, unclear microscopic observation, inaccurate counting, and poor airtightness. Inconvenient operation and inaccurate detection results. Conte...
