A cell capture device suitable for medical testing

Abstract

The invention relates to the technical field of cell detection, in particular to a cell capturing device for medical inspection. The cell capturing device aims at solving the problems of the prior artthat the single cells are difficult to separate out due to lack of separation structure, and the cell stress is concentrated due to unreasonable design of the capturing mechanism. The cell capturingdevice for the medical inspection comprises a microfluid substrate, a microfluid cover plate, a separation clapboard, a fluid guide inlet, a culture medium inlet, a fluid guide outlet, a first fluid blocking plate, a second fluid blocking plate, and an outlet opening and closing plate, wherein the microfluid substrate is arranged under the microfluid cover plate and is integrally bonded with the microfluid cover plate; the separation clapboard is movably arranged in the microfluid substrate. A microfluidics cell capturing device is adopted, and has the advantages that the convenience in use isrealized for an inspector; the stress concentration is avoided in the fluid channel; the cell dissolving and cell injury due to unreasonableness of capturing structure are furthest avoided.

Description

Technical field [0001] The present invention relates to the technical field of cell detection, in particular to a cell capture device suitable for medical testing. Background technique [0002] As the number one killer threatening human life and health, people are paying more and more attention to cancer research, and the metastasis of cancer cells has been plagued by scientific research and medical workers. How to quickly and effectively separate cancer cells from tissue fluid and peripheral blood Cancer cells are the primary task for further study of cancer cell metastasis and pathogenesis. At this stage, the industry mainly uses flow analyzers as the main method of cell separation. In practical applications, it has been found that the flow analyzer has problems such as complicated operation procedures, separation process affecting cell viability, and difficulty in obtaining single cells. Therefore, with the in-depth research on microelectromechanical systems in academia, the ...
