The invention relates to a liquid-based
cell smear manufacturing and
dyeing machine utilizing principles of injection and pipetting, which is characterized by structurally comprising a
machine base, a
machine body, a worktable, a horizontal slide rail, a moving arm, a horizontal motor moving device, an up-down motor moving device and a
microcomputer motion control system, wherein four groups of smear manufacturing and
dyeing units and a kit are mounted on the worktable board; and 24 samples can be automatically manufactured into smears and dyed when the machine runs once. The liquid-based
cell smear manufacturing and
dyeing machine does not need a tedious
specific gravity liquid
gradient centrifugation step, a
micropipe type liquid drawing
system of a liquid-based
cytology test (LCT) machine, or processes of vacuum negative pressure drawing and
positive pressure cell transfer of a microporous filter membrane of a Thinprep
cytology test (TCT) machine.
Cell samples are drawn, evenly mixed and scattered by using a pipetting
injector and sample reagents are transferred by utilizing an accurate quantitative liquid drawing and injecting function of the pipetting
injector. Cells in a
settling and smear-manufacturing bin are naturally settled on a sticky
glass slide by relying on the gravity of the cells and then automatically dyed. The liquid-based
cell smear manufacturing and dyeing machine has the advantages that the operation is simple, the cost is relatively low, and high quality liquid-based cytological smears can be rapidly manufactured.
