Abstract

The invention belongs to the field of liquid-based cell pelleting, in particular to a cell collecting device of a membrane type liquid-based cell pelleter. Proposed now is the following scheme: the cell collecting device comprises a second shell, a first shell is fixedly mounted at the top of the second shell; an air cylinder is fixedly mounted at the upper end of the first shell; the output end of the air cylinder is connected with a lifting rod; the lower end of the lifting rod penetrates through the first shell and extends into the first shell, and a collecting box is fixedly mounted; a mounting through hole is formed in the upper end of the second shell; the lower end of the collecting box penetrates through the mounting through hole and extends into the second shell; and two rectangular through holes are symmetrically formed in the left end and the right end of the collecting box, filter membranes are fixedly mounted on the inner side walls of the two rectangular through holes inthe vertical direction, a motor is fixedly mounted at the right end of the first shell, and a two-way lead screw is connected to the output shaft of the motor. The cell collecting device is good in separation effect, convenient to collect, high in automation degree, easy to operate and high in practicability.

Description

technical field [0001] The invention relates to the field of liquid-based cell preparation, in particular to a cell collection device of a membrane-type liquid-based cell preparation machine. Background technique [0002] The liquid-based cell production machine can evenly distribute a thin layer of cells on the carrier, which overcomes the problems of too thick material, cell overlap, blurred background and poor staining in the traditional Pap smear technology, and the liquid-based cell production The chip machine can repeatedly copy the same sample, which is more conducive to the accurate diagnosis and screening of pathological cells. This technology helps to screen abnormal cells, improve the sensitivity and specificity of cervical lesion screening, make it easier to detect early cancers, reduce the incidence of advanced cancers, and reduce the mortality rate of cervical cancer. [0003] The working principle of the commonly used membrane-type liquid-based cell slicer is...
