Abstract: This study is aimed to design the testing system of multiple parameters of the incubators, and to make their quality control plans. Also it is required to establish a model of data collection and processing based on MCU, and to program the host computer software in order to analyze data. The result shows that the testing system is accurate and stable; also it is convenient to collect the data. This testing system is a good complement of the quality control of incubators. It has a high practical value in improving medical safety and reducing the occurrence of adverse events.
