摘要

The invention concerns a method concerns a method for indicating if a bag can be delivered by transfusion to a patient or not, whereon is fixed permanently an electronic chip equipped with an antenna capable of communicating with an electronic communication device (80) and a simplified electronic communication device (75, 77) equipped with a loop antenna connected to a programmable automaton (76, 71), whereby an expiry date is defined, from an initial time determined by taking a sample in a parent blood bag in a blood transfusion centre (63) by means of the electronic communication device (80) integral with a stirring spring balance (81), said expiry date being posted in the electronic chip of a parent blood bag then transferred into the electronic chip of a primary blood bag then into the electronic chip of secondary blood bags and whereby is also defined a maximum authorized residence time dT outside a chamber with controlled atmosphere (64, 65), for qualifying anew the blood bag when it is returned to the chamber if dT and the expiry date have not elapsed and for disqualifying it if dT or the expiry date have elapsed so as to destroy it.
