Abstract：Objective Aiming at the problems of the low efficiency, poor stability and low success rate in making blood smear by
manual mode, a new type automatic blood smear maker integrating functions of pushing and staining was developed. Methods
First of all, mechanical system of the blood smear maker was designed refering to methods of preparing manual blood smear. Then,
hardware system based on the STM32 processor and software system based on real time operating system uC/OS-III were designed.
In addition, a PC operation interface based on VC++ was developed. Finally, experiments related to pushing and staining of blood
smear were carried out. Results Blood smear maker could produce qualified blood smear, which was more efficient and successful
in making blood smear compared to manual mode, and the quality stability of blood smear was improved. The experiment results
showed pushing velocity, pushing angle and staining times had an important influence on quality of blood smear. Conclusion A new
design scheme of automatic blood smear maker is put forward. The designed blood smear maker can realize functions of automatic
pushing and staining of blood smear and has a positive effect on promoting the development of China-made full-automatic blood
smear maker.
