Membrane type liquid-based thin layer cell tableting machine

Abstract

The invention relates to a membrane type liquid-based thin layer cell tableting machine comprising a rack and a filter membrane cup disposed on the rack, wherein the filter membrane cup comprises a liquid take-up tube and a liquid storage tube which are sleeved to each other, a conical tube inserted into the container is disposed in the liquid take-up tube, the liquid storage tube is internally provided with a liquid storage film abutting the bottom of the conical tube, the rack is provided with a liquid take-up fixing device and a liquid storage driving device; a glass slide capable of extending between the liquid take-up tube and the liquid storage tube is slidably disposed on the rack in the horizontal direction; and the rack is also provided with a suction device communicated with theliquid storage tube and generating negative pressure when the liquid take-up tube and the liquid storage tube are sleeved. Since the filter membrane cup is disposable and can be disposed of after use,which can effectively avoid the contamination when sucking different cell base fluids. At the same time, since the filter membrane cup is disposable and can be directly thrown after use, the operation is very convenient without repeated cleaning of the tableting machine.

Description

technical field [0001] The invention relates to the technical field of slicers, in particular to a membrane-type liquid-based thin-layer cell slicer. Background technique [0002] Most of the existing membrane-type liquid-based thin-layer cell slicers use a negative pressure pump to filter multiple filter membrane cups at the same time, and the pressure will be uneven. For the same suction time, residual liquid in the membrane cups is likely to occur, resulting in Cross-contamination. [0003] The utility model with the notification number CN 208026527U provides a membrane-type liquid-based thin-layer cell slicer. By setting up multiple negative pressure pumps and connecting the filter membrane cup and the solenoid valve in parallel, a stable and large-flow suction force is obtained to ensure that the pumping liquid effect. [0004] When in use, it is necessary to suck out the cell base fluid in the filter membrane cup through the tip of the dipping tube, and then transfer...

AI Technical Summary

Problems solved by technology

[0004] When in use, it is necessary to suck out the cell base fluid in the filter membrane cup through the tip of the dipping tube, and then transfer the cells to the glass slide through photoelectric induction and pressure sensing to complete the output of the cells. During operation, the dipping tube The tip will repeatedly absorb the cell base fluid. When it is necessary to transfer different cells, if the tip of the dipping tube is not cleaned in time, there will be mixing of different sample cells, resulting in inaccurate test results, but often It is very inconvenient to clean the dipping tube head
