Cell smearing apparatus and cell smearing method
A cell smearing apparatus comprising: a mixed solution container accommodation unit accommodating a mixed solution container containing a mixed solution of cells and a preservation solution; a suction unit suctioning the mixed solution from the mixed solution container accommodated in the mixed solution container accommodation unit; a sensor unit sensing variation of the mixed solution suctioned by the suction unit; and a controller controlling a suctioning speed of the suction unit based on a value sensed by the sensor unit. The present invention allows cells to be examined to be smeared as a monolayer on a slide for microscopic examination.
1. A cell smearing method comprising:
(a) coupling an upper body of a mixed solution container to a mixed solution container accommodation unit of a case, the mixed solution container including the upper body and a lower body detachably coupled to the upper body;
(b) lifting a tray to couple a suction unit of the tray to the mixed solution container accommodation unit;
(c) suctioning the mixed solution of the mixed solution container accommodation unit through the suction unit;
(d) lowering the tray to separate the lower body from the upper body;
(e) coupling a slide to a slide accommodation portion of the case; and
(f) lifting the tray to allow cells filtered through a filter of the lower body to be stamped on the slide coupled to the slide accommodation portion.
2. The cell smearing method according to claim 1 , wherein in the step of (c) suctioning the mixed solution of the mixed solution container accommodation unit through the suction unit, a pressure sensor senses pressure of the mixed solution suctioned by a suction unit, and a controller controls the suction unit to suction the mixed solution at a reduced speed when the pressure of suctioning the mixed solution sensed by the pressure sensor reaches a predetermined pressure.
3. The cell smearing method according to claim 1 , wherein, before the step of (c) suctioning the mixed solution of the mixed solution container accommodation unit through the suction unit, (b′) a concentration analyzer measures a concentration of the mixed solution in the mixed solution container accommodated in the mixed solution container accommodation unit, and a preservation solution supplier additionally supplies the preservation solution to the mixed solution container accommodation unit when the concentration of the mixed solution measured by the concentration analyzer exceeds a predetermined value.
