INJECTION ENDPOINT MONITORING SYSTEM AND METHOD

Abstract: an injection endpoint monitoring system is configured for integration into an injection monitoring module mounted on a proximal end of a pen injection system comprising a proximal activation button. the monitoring system comprises a processor, a magnetometer, and an accelerometer, electrically connected to the processor, which is configured to receive data and/or information from either the magnetometer and/or the accelerometer. a magnetic field generator is configured to provide a magnetic field detected by the magnetometer, and is rotatable about a first axis, and located on, and translatable along, the first axis. the processor is configured to process data and/or information received synchronously from both the magnetometer and the accelerometer to determine whether a dose setting operation has been effected, whether a translational movement of the accelerometer along the first axis of the system has occurred, and to determine an endpoint of an injection operation of the pen injection system.
