A medication delivery device is disclosed having a dose detection system and an associated control system configured to determine an amount of medication delivered from the medication delivery device based on the sensing of relative rotation within the medication delivery device. The relative rotation may occur between a dose setting member and an actuator and/or housing of the medication delivery device. The rotation sensing may involve sliding contact sensing. A latch circuit may be coupled between the rotational sensor and the controller. The dose detection system may be a modular or integral component of the medication delivery device.

Medication delivery device with dose detection system

Medication delivery devices are provided having a dose delivery sensing capability. A dose button includes a support and a cover that at least partially encloses an electronics assembly including a sensor for detecting rotation of a component during dose delivery to determine a dosage of delivered medication. The electronics assembly includes a controller for receiving a signal from the sensor. The medication delivery device may be configured to communicate dosage delivery information to an external device.

Medication delivery device with sensing system

An injection device assembly including a housing, a syringe, a drive mechanism and a status sensing system and a module are described. The drive mechanism advances the syringe from a storage position to an injection position, and a plunger advances the syringe piston from an initial position to a final position. The status sensing system includes a light emitter that emits electromagnetic radiation into the housing transverse to the longitudinal axis, a light detector and a controller. The system determines a current status condition from at least three of the following five status conditions: 1) an injection ready state; 2) a needle insertion state; 3) a drug delivered state; 4) a needle guard present state; and 5) a needle retraction state.
