Device for concentrating cells in samples of discharged/extracted substances

The utility model relates to a device for concentrating cells in samples of discharged/extracted substances and a special scraping device. The device comprises a cover, a membrane and a bracket, which are provided with through holes respectively, wherein the diameter of the membrane is greater than the lower diameter of the through hole in the cover; the membrane is arranged between the cover and the bracket and completely covers the through hole in the cover; the cover is fixedly connected with the bracket. The device can treat all samples of discharged/extracted substances of human or animal, and extract the cell amount desired in the preparation of a post medical cell paraffin block, so that the detection of a cell paraffin block containing exfoliated cells in human or animal body required for inspection and pathological analysis is realized, the sampling is comprehensive, the detection accuracy is improved. The special scrapping device is used for scrapping concentrated cells on the membrane after the bracket is removed; thin sugar, albumen, ice or rice milk are stuck to the ends of the scrapping device; when the cells are extracted from the scrapping device by rinsing, flushing, dissolving and other ways, the cells are easier to be separated from the scrapper device, so that the sample scrapping effect is improved without affecting the detection result.
