The world health organization and the international red cross and red crescent motion have called for the principle of' medical blood donation using uncompensated blood "to countries in the world, and China encourages uncompensated blood donation, and donation of whole blood is a way in uncompensated blood donation. When whole blood is donated, a blood donor goes to a nearby blood center, a blood station or a movable blood collection point, and a professional blood collection nurse performs standardized blood collection operation. The whole operation flow comprises registration before blood sampling, physical examination, confirmation, blood sampling, propaganda and education and post-blood sampling treatment.

At present, before blood sampling, a blood sampling nurse finishes registration, physical examination and confirmation before blood sampling mainly through a plurality of scattered handheld mobile terminals, conventional detectors and manually filled paper registration forms, and data and information generated in the process are integrated in a blood center management system through manually inputting the information of the paper registration forms or uploading the data of the handheld mobile terminals.

During blood sampling, links such as identity confirmation, disinfection puncture, blood sample retention, blood sampling, communication and propaganda and education of blood donors are involved, and blood sampling is completed basically depending on the acquaintance of nurses on operation specifications, operation experience and working attitude at present. Some manufacturers have also provided automated devices to automatically complete the retention and collection of blood samples.
