Description

Technical Field

[0001] The utility model belongs to the technical field of blood product transportation, and particularly relates to a management system for the transfer of blood products between blood bank departments. Background Art

[0002] At present, blood centers are set up in China to preprocess and store and manage blood. In the blood management process, various data need to be recorded, including the identity information of blood donors, the type and quality of the blood itself, the time and place of blood collection, the information records of blood out of the warehouse and into the warehouse, etc. Due to the large amount of information, how to quickly collect and record is an important issue to improve the work efficiency of blood stations. At present, RFID technology is mostly used to automatically identify target objects through radio frequency signals and obtain relevant data. Using RFID technology to supervise blood products greatly reduces the labor intensity of manual work and realizes fast information entry.

[0003] However, the radio frequency signal decays severely when passing through liquids, and data reading errors often occur. The reading errors are mainly reflected in: 1) Missing part of the item information, resulting in the situation that the automatically entered number of items is lower than the actual number of items, so that some items entering the warehouse have no records; 2) Or reading the information of other items outside the specified range, then the actual number of items entering the warehouse is lower than the recorded number. This seriously affects the accuracy of data statistics, causing great trouble to blood management and affecting medical safety. Content of the Utility Model
