Abstract
A drug delivery device (), including a delivery unit () comprising a subcutaneous delivery system including a needle support (), an injection needle () mounted on the needle support, and an injection needle actuation mechanism configured to engage and slidably move the needle support from a retracted position where the injection needle is within a housing () of the drug delivery device to an extended delivery position where the injection needle projects through a skin contact wall of the housing. The needle actuation mechanism comprises a slider-crank linkage mechanism () comprising a crank rod () pivotally connected to the housing, a connecting rod () pivotally connected to the crank rod and pivotally connected to the slidable needle support (), and a spring () biasing the slider-crank linkage mechanism from a first retracted position prior to use where the needle is fully inserted within the housing towards an extended position for drug administration and further to a second retracted position after use.
