    Abstract: A real-time drug injection time duration measurement system includes a sound transducer, a waveform shaping circuit operably coupled therewith, a pulse clamping circuit operably coupled with the waveform shaping circuit, and a timer operably coupled with the pulse clamping circuit. The sound transducer detects a first sound associated with drug delivery initiation and a second sound associated with drug delivery completion and is further converts the detected first and second sounds into a first electronic waveform and a second electronic waveform, respectively. The waveform shaping circuit converts the first and second waveforms into a first pulse and a second pulse, respectively. The pulse clamping circuit triggers upon receiving the first pulse and generate a regenerated pulse. The timer initiates upon receiving the regenerated pulse and stop upon receiving a subsequent regenerated pulse via the pulse clamping circuit.

    Abstract: The present disclosure relates to a drug delivery device. The drug delivery device includes a housing having a proximal end and a distal end. Additionally, a needle guard disposed at the proximal end of the housing and movable in an axial direction relative the housing between a first position and a second position. A storage container, disposed within the housing for storing a drug, includes a needle for administering the drug. The drug delivery device also includes an injection activation button disposed on the distal end of the housing and including a fingerprint detector. Additionally, the present disclosure includes a lock configured to switch between a locked configuration inhibiting actuation of the drug delivery device and an unlocked configuration enabling actuation of the delivery device. The lock is in the unlocked configuration when the needle guard is in the second position and the fingerprint detector detects a fingerprint.
