US Patent 10398852 Smart adapter for infusion devices

Smart sensors are employed to determine one or more of drug identification, dose, flow rate, concentration, agglomeration, and degradation and/or other characteristics of drug administration that can be detected via sensing technology. A smart sensor(s) can be coupled to or retrofitted onto injection pen injectors and/or drug delivery cartridges and/or infusion sets or cannulae, enabling infusion sets, pen injector systems or drug delivery cartridges to improve tracking of drug self-administration and stop medication errors that occur primarily through self or automated injection (e.g., due to incorrect or incomplete dosing, excessive dose or rate, incorrect drug, or drug degradation).
