Special filter membrane surface cell counting plate for detecting circulating tumor cells

Abstract

The invention provides a special filter membrane surface cell counting plate for detecting circulating tumor cells. The special filter membrane surface cell counting plate comprises a glass slide, wherein a filter membrane placing region is mounted on the surface of the glass slide; a counting plate formed by square cells is arranged at one side of the filter membrane placing region above the glass slide; the sizes of the counting plate and the glass slide are adapted to that of a glass slide placing region. After being repeatedly tested and used, the special filter membrane surface cell counting plate has the advantages that the circular filter membrane placing region is arranged on the glass slide for placing a filter membrane; the glass slide is placed in the glass slide placing region of the counting plate; the position of the filter membrane corresponds to a counting region of the counting plate; the counting is very accurate; each straight line has codes, cell counting can be corrected to a specific coordinate position and region division can also be carried out; the counting accuracy is improved and the operation is convenient; the special filter membrane surface cell counting plate is good for recording and analyzing; the working efficiency is improved and the practicability is strong; the special filter membrane surface cell counting plate is suitable for general popularization and application.

Description

technical field [0001] The invention relates to the field of filter membrane detection methods for counting tumor cells according to their size, in particular to a novel membrane surface cell counting plate dedicated to circulating tumor cells. Background technique [0002] The present invention is based on the national key basic research and development plan (973 plan) project, and the number is 2011CB504302 to develop an improved membrane filtration circulating tumor cell detection system. After screening, the circulating tumor cells remain on the surface of the filter membrane for accurate counting. However, due to the absence of reference objects on the filter membrane surface, repeated counting and omissions are often caused, resulting in inaccurate detection results. The detected circulating tumor cells are relocated. Difficulty, which leads to the difficulty of repeated verification of the results; currently there is no equipment specifically for cell counting on the ...

[0002] The present invention is based on the national key basic research and development plan (973 plan) project, and the number is 2011CB504302 to develop an improved membrane filtration circulating tumor cell detection system. After screening, the circulating tumor cells remain on the surface of the filter membrane for accurate counting. However, due to the absence of reference objects on the filter membrane surface, repeated counting and omissions are often caused, resulting in inaccurate detection results. The detected circulating tumor cells are relocated. Difficult, which leads to the difficulty of repeated verification of the results; currently there is no equipment specifically for cell counting on the surface of the filter membrane, to make up for the blank of this related product, to develop a special filter surface cell counting board for circulating tumor cells detection
