Medication delivery device with mechanical locking system

A medication delivery device connectable to an electrical plug of a conduit for at least one of charging and data transfer, the medication delivery device comprising:

• an external housing having an outer surface and defining an interior volume, said outer surface defining an opening that ports to a plug receiving hollow within said interior volume;
• a dose delivery assembly operable for forcing medication from the device;
• an electrical circuit within said interior volume connected to at least one of a rechargeable battery and a memory controller within said interior volume, said electrical circuit including a connection element within said plug receiving hollow for electrically interfacing with the plug when the plug is inserted, from external to the external housing, through the opening into the plug receiving hollow;
• a lock element within said interior volume operably connected to said dose delivery assembly to travel within said plug receiving hollow when said dose delivery assembly operates for forcing medication from the device, said lock element sized and positioned to have its travel halted by abutment with the plug, when the plug is within the plug receiving hollow and electrically interfacing with said connection element, to thereby halt said dose delivery assembly from further operating for forcing medication from the device.
