Abstract
A blood smear preparation device includes a base; a carrying table for carrying a microscope slide thereon and being supported on the base; a lifting mechanism mounted to the base; a retaining stand suspended from an output end of the lifting mechanism; a spreader holder rotatably suspended from the retaining stand about a second rotating shaft and positioned above the carrying table; a positioning member for positioning the spreader; and a torsion elastic member provided about the second rotating shaft, with a free end of the torsion elastic member abutting against the spreader holder. With the provision of the second rotating shaft and the torsion elastic member, the spreader has a certain degree of flexibility and self-adaptiveness. Even if the spreader or the microscope slide has no good micro-flatness or straightness, the device may automatically adjust the positions of the spreader and the microscope slide to achieve a line contact and a surface contact, and thus ensure the quality of the blood smear.
