The present disclosure relates to drive unit (3) of a drug delivery device (1) configured for setting and dispensing of a dose of a medicament, the drive unit (3) comprising: a drive unit housing (9) extending along a longitudinal axis (A), the drive unit housing (9) comprising a distal end (4) and a proximal end (5), a first interface (110) provided at the distal end (4), configured to connect with at least one of a container unit (2) and a protective cap (14), the first interface (110) comprising at least a first electrical contact element (111, 112), an electronic unit (70) arranged on or inside the drive unit housing (9), a first elongated device component (40) extending along the longitudinal axis (A), a first electrical conductor path (141) located on or inside the first elongated device component (40), the first electrical conductor path (141) comprising a first path distal end (142) and a first path proximal end (143), wherein the first path proximal end (143) is connected to the electronic unit (70) and wherein the first path distal end (142) is connected to the first electrical contact element (111, 112), wherein the electronic unit (70) is operable to execute an electronically implemented function in response to receive an electric detection signal via the first electrical conductor path (141).
A drive unit (3) of a drug delivery device (1) configured for setting and dispensing of a dose of a medicament, the drive unit (3) comprising:
The drive unit (3) of any one of the preceding claims, further comprising a second device component (60) movable relative to the first device component (40) for at least one of setting of the dose and dispensing of the dose of the medicament, wherein the electronic unit (70) is arranged on or in the second device component (60) and wherein a first electrical conductor path extension (145) located on or inside the second device component (60) is electrically connected to the electronic unit (70) and is electrically connected to the first electrical conductor path (141).
The drive unit (3) of any one of the preceding claims, further comprising an electromechanical actuator (50) electrically connected to the electronic unit (70) via a first electrical control path (181) and a second electrical control path (191) electrically isolated from the first electrical control path (181), wherein the electronic unit (70) is operable to selectively activate or deactivate the electromechanical actuator (50) by generating and transmitting at least one control signal to the electromechanical actuator (50) via the first and second electrical control paths (181, 191).
The drive unit (3) according to any one of the preceding claims, further comprising:
A drug delivery device (1) for setting and dispensing of a dose of a medicament, the drug delivery device comprising:
