Cell preserving and centrifugal filtering device

Abstract

The invention discloses a cell preserving and centrifugal filtering device. The cell preserving and centrifugal filtering device comprises a transparent cylindrical hollow tube, wherein a funneled filter funnel is arranged on the upper inner side of the transparent cylindrical hollow tube; a guide pipe is arranged at the bottom of the filter funnel; a filter screen is arranged between the guide pipe and the filter funnel; the bottom of the transparent cylindrical hollow tube is in threaded connection with a bottom cover; a support pillar is arranged on the upper surface of the bottom cover; a circular-arc-shaped groove is formed in one side of the transparent cylindrical hollow tube; a glass slide is inserted into the transparent cylindrical hollow tube through the circular-arc-shaped groove. The cell preserving and centrifugal filtering device has the advantages that the structure is simple, the functions are diversified, the working efficiency is effectively improved, consumables are reduced, disorder is prevented, and the probability of cross contamination is reduced.

Description

technical field [0001] The invention relates to the field of cell detection equipment, in particular to a centrifugal filter device for cell preservation. Background technique [0002] In the production process of liquid-based cytology technology, when cells are subjected to centrifugal filtration and sedimentation for production, sample transfer machines, film production machines, pipetting syringes, centrifuge tubes, film production chambers (or film production clips), Various instruments, equipment and devices such as glass slides are costly. During the operation, samples need to be manually transferred or added between multiple instruments and equipment. The process is cumbersome and lengthy; and when transferring and adding multiple cell samples When sampling, it is easy to have upside-down and cross-contamination phenomenon in human operation, which seriously affects the accuracy of cell detection; samples are easily lost and polluted people, objects and the environmen...

[0002] In the production process of liquid-based cytology technology, when cells are subjected to centrifugal filtration and sedimentation for production, sample transfer machines, film production machines, pipetting syringes, centrifuge tubes, film production chambers (or film production clips), Various instruments, equipment and devices such as glass slides are costly. During the operation, samples need to be manually transferred or added between multiple instruments and equipment. The process is cumbersome and lengthy; and when transferring and adding multiple cell samples When sampling, it is easy to have upside-down and cross-contamination phenomenon in human operation, which seriously affects the accuracy of cell detection; samples are easily lost and polluted people, objects and the environment during the transfer process, resulting in an increase in the missed diagnosis rate of cell detection and biosafety hazards.
