Patent number: 11404152Abstract: A data collection device is configured to capture images of a dosage indicator of a medicament delivery device and, if an injection is administered without prior confirmation of a dosage amount, to prompt the user to set a value for the delivered medicament dosage amount for storing in a dosage log. For example, the determination may be based on specific confirmation from the user or detecting a zero dosage amount in captured images. A suggested dosage amount may be displayed to the user, for example a highest or more recently programmed dosage amount prior to the injection or based on one or more previously confirmed dosage amounts. The data collection device may use one or more of optical character recognition, optical pattern recognition and determination of direction of rotation of a dosage adjustment component to determine whether an injection is being, or has been, administered and/or a suggested dosage amount.Type: GrantFiled: November 10, 2015Date of Patent: August 2, 2022Assignee: Sanofi-Aventis Deutschland GMBHInventors: Stephan Riedel, Isabel Klein, Alexander Allerdings, Christian Nessel
