Medical errors can have serious consequences, but mistakes during blood transfusions are particularly unacceptable. Though such errors are rare, they do still occur, and Typenex Medical, a Chicago, Illinois company, has created a solution that pretty much eliminates the possibility for errors.
The system utilizes a combination lock on the blood bag that will only open using a code printed on the patient’s armband. If a clinician accidentally attempts to open the bag using another patient’s code, it will stay closed and the transfusion will not happen.
