Development status and prospect of on orbit precision testing instruments for aerospace medicine

Aerospace medical on orbit inspection instruments have played a great role in the on orbit health inspection and monitoring of astronauts because of their high detection accuracy, portable use and strong environmental adaptability. This paper briefly describes the main detection methods of on orbit medical detection instruments, including electrochemical method, dry chemistry method, flow cytometry combined with fluorescence detection technology, chemiluminescence immunoassay technology and enhanced Raman spectroscopy. The application direction and current situation of on orbit precision detection instruments in the field of aerospace medicine are introduced, and their future development trends are prospected.
