A blood smear drying method, device and smearing device; when drying a blood smear, using dry gas as a drying medium for the blood smear dries the blood film on the blood smear, thus reducing the drying time of blood smears and the number of stored blood smears. The drying medium is obtained by: first removing liquid water from high-pressure gas, then filtering out the water vapor, and finally depressurizing the high-pressure gas to normal pressure to obtain a drying medium with relatively low humidity. In addition, provided is another preferred embodiment: heating the drying medium, to reduce the relative humidity of the heated drying medium. In order not to cause deformation of blood film cells, preferably directing the heated drying medium in the spread direction of the blood film on the blood smear, thus completely drying the blood smear, reducing the possibility of deforming of the blood film, improving the drying quality of the blood smear. |
