Abstract: Clinical transfusion is one of the important treatment of severe hemorrhage patients. Timeliness is a key factor of curative effect in transfusion therapy. Many complicated process and many departments are involved. Therefore, it is imperative to build a standard, reasonable and effective paperless process of clinical transfusion. The paperless process transforms the traditional paper-based documents into seamless connections between programs. It is mainly composed of three modules, information interaction, compatibility test and transfusion closed-loop. This process improves the work efficiency, reduces the error rate, saves energy and storage space. It also has realized the safety management of standardization, informationization and paperless transfusion closed-loop.

Key words: Clinical Transfusion, Transfusion Closed-loop, Paperless, Informationization, Safety management
