Combination lock to prevent blood transfusion errors? Why not

medGadget: “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.” – Simple, yet effective. Interesting concept, no?

The product is called FinalCheck.
