An apparatus (1000, 3002, 3006, 3007), comprising: a housing (1100, 3110, 3116, 3182) having a distal end portion and a proximal end portion, the distal end portion includes a distal end surface; a medicine injector including a medicine container (3262) and a needle (3212, 6100), the needle configured to move within the housing between a first needle position and a second needle position, in the first needle position the needle is contained within the housing, in the second needle position at least a part of the needle extends from the distal end part of the housing; an energy storage member (2400, 2412, 3412) having a first configuration and a second configuration, the energy storage member configured to produce a force when transitioning from the first configuration to the second configuration to move the needle between the first needle position and the second needle position; and a drive member (3540, 7540, 9540, 10540) configured to transition the energy storage member from its first configuration to its second configuration when the drive member is moved from a first position to a second position; and a locking member (3130, 3170) configured to detachably engage the distal end portion of the housing, a protrusion (3128, 3178) of the locking member disposed through an opening defined by the distal end surface of the housing such that the protrusion engages the actuating member to prevent movement of the actuating member from the first position to the second position when the locking member engages the distal end portion of the housing. |
