Data transmission between data chip attached to blood bag and computer chip of weighing device, avoiding all risk of error

摘要

Data is transmitted through a loop antenna integrated in the weighing tray (6) on which a blood bag (13) carrier (10) is placed. An integrated circuit (12) attached to a blood bag is connected to a loop antenna (43). The carrier antenna (15) is connected through a cord (19) to the weighing device computer. Data is transferred to the blood bag chip before the bag is lifted from the carrier.
