[0002] Currently, in vitro diagnostic medical device technology has matured significantly, and achieving fully automated testing has become an important development direction for the industry. In this process, the automatic identification of sample identity information is a crucial step in realizing the association, storage, and processing of test results. Currently, the industry commonly uses barcodes affixed to the outer wall of test tubes to mark sample information; the testing instruments obtain sample data by reading the barcodes on the test tubes.
