Liquid absorption mechanism and working method thereof

Abstract

The invention relates to a liquid absorption mechanism and a working method thereof. The mechanism comprises a bracket, a centrifuge bottle, a control chip, a liquid absorption component and a visualinspection component, wherein the visual inspection component comprises a camera component and a visual controller; the camera component and the visual controller are connected; the visual controllerand the liquid absorption component are independently connected with the control chip; the centrifuge bottle, the camera component and the liquid absorption component are connected to a bracket; the photo of the centrifuge bottle is shot through the camera component; and after the visual controller carries out photo analysis, liquid layering position information is obtained, the liquid layering position information is sent to the control chip, and the control chip drives the liquid absorption component to carry out an absorption operation of an upper-layer clear liquid in the centrifuge bottle. By use of the liquid absorption mechanism disclosed by the invention, the fully automatic absorption of the upper-layer clear liquid is realized, and in addition, liquid separation accuracy is highby visual identification and inspection.

Description

technical field [0001] The invention relates to a liquid suction mechanism, more specifically to a liquid suction mechanism and its working method. Background technique [0002] In the process of cell preparation, the liquid of the transferred cells needs to be centrifuged, and the cultured stem cells are stripped from the culture dish, which contains both stem cells and culture fluid, and after being separated by a centrifuge, the cells are precipitated on the centrifugal screen. At the bottom, the centrifuged supernatant needs to be separated from the centrifuge bottle for cell culture. [0003] At present, in the manual or automated stem cell preparation process, the supernatant is taken out by the operator manually pouring the liquid quickly, which has a low storage efficiency, and some cells are prone to flow out with the supernatant during the operation. Or, the colloidal dispersion system formed by dispersing and suspending the small particles of the supernatant in t...

[0003] At present, in the manual or automated stem cell preparation process, the supernatant is taken out by the operator manually pouring the liquid quickly, which has a low storage efficiency, and some cells are prone to flow out with the supernatant during the operation. Or, the colloidal dispersion system formed by dispersing and suspending the small particles of the supernatant in the gas medium will cause cross-contamination to the environment, or during the process of pouring the liquid, some of the liquid will stick to the wall of the culture dish and cannot be separated cleanly, thus causing the cell Reduced success rate
