Liquid-based thin-layer cell sheet production clamp

Abstract

The invention discloses a liquid-based thin-layer cell sheet production clamp, belongs to a vertical sheet production clamp for a centrifugal liquid-based thin-layer cell sheet production machine andaims at providing the liquid-based thin-layer cell sheet production clamp capable of reducing outflow of cells on a glass slide with water and furthermore ensuring that the cells on the glass slide are collected. A technical scheme of the liquid-based thin-layer cell sheet production clamp has the key points that a baffle is arranged between inner walls of lower ends of sedimentation tubes; the lower end of the baffle is in contact with the glass slide; the baffle is arranged to be close to the center position of the sheet production machine, and the length of the baffle is smaller than the diameter of the sedimentation tube; a space formed by the sedimentation tube and the glass slide is divided into a cell sedimentation region and a water absorption region by the baffle; the cell sedimentation region is arranged to be close to the center position of the sheet production machine; the upper end of the baffle is provided with a moving plate located on the same plane with the baffle; oneend of the moving plate is hinged with the inner wall of the sedimentation tube, and the other end of the moving plate is in contact with the inner wall of the sedimentation tube; the moving plate isprovided with a tension spring above the cell sedimentation region; and the inner wall, located in the water absorption region, of the sedimentation tube is provided with water absorption cotton.

Description

technical field [0001] The invention relates to a vertical film-making clip for a centrifugal liquid-based thin-layer cell film maker, in particular to a liquid-based thin-layer cell film-making clip. Background technique [0002] In medicine, the observation of cell smears can be used to screen and diagnose female cervical cancer and other diseases. The screening of exfoliated cells includes the following steps: use a sampler to collect specimens, store in preservation solution, oscillate and mix, base fluid thin layer of cells Film preparation and microscope observation. One of the important steps is the production of liquid-based thin-layer cells, that is, transferring useful cells to glass slides to make cell smears with clear background, neat and uniform cells, and single-layer tiling for inspection and research by researchers. However, the exfoliated cells sampled during film production often contain impurities such as mucus and red blood cells, resulting in an unclea...

Problems solved by technology

When the cell slicer is centrifuged, the water in the liquid-based cells in the settling tube is separated from the cells due to centrifugation. At this time, the cells are adsorbed on the glass slide, and then the water is poured out through the settling tube. The cells adsorbed on the glass slide will also flow out with the water during the process, which is not conducive to the collection of cells on the slide
