Abstract

The invention discloses a membrane type collecting system and method for liquid-based cell, belonging to the cell-collecting device and method of cell smear processing equipment. The prior art has the drawbacks of uneven quantity of cell collection, incompletion of cell and inconvenience for observation. The invention comprises a filtering device, a pressure feeding device for the filtering device, a controller. In the filtering device is provided a filter, which is a sealed vessel, and on which are provided with a liquid suction hole and an air vent; the liquid suction hole is covered by a filtrating membrane, and the air vent is provided with a windpipe to connect the filter with the pressure feeding device; on the filter is also provided with a filter pressure sensor to supervise the filter pressure; the filter pressure sensor and the pressure feeding device are connected with the controller. The invention has the advantages of realizing the basically constant quantity of cell collection, guaranteeing the completion of cells, removing the impurity, preventing from the cells deposit, as well as being convenient in use, observation and diagnosis.

Description

【Technical field】 [0001] The invention relates to a cell collection device and method for cell smear manufacturing equipment, in particular to a cell collection system and method for a membrane-type liquid-based cell slicer. 【Background technique】 [0002] The traditional cell collection method is to collect cell samples through cotton swabs, cervical brushes or scrapers, and then apply the collected cells on glass slides, and then put the glass slides into a fixative solution to fix the cells. [0003] With this method of collection, most of the cells (more than 80%) remained on the swab or cervical brush or scraper and were thrown away, and very few cells were transferred to the glass slide, and because of the manual method, each The number of cells collected is uneven and lacks representativeness; impurities, inflammatory cells and blood cannot be removed during collection, they overlap with cells, and cells themselves will also accumulate and overlap, hindering observati...
