Medication delivery device with mechanical locking system
A medication delivery device having a lock element. The device is connectable to an electrical plug of a conduit. The device includes an external housing with an opening that ports to a plug receiving hollow within an interior volume. An electrical circuit connected to at least one of a rechargeable battery and a memory controller includes a connection element within the plug receiving hollow. The lock element travels within the plug receiving hollow when a dose delivery assembly of the device operates for forcing medication from the device. The lock element is 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 the connection element, to thereby halt the dose delivery assembly from further operating for forcing medication from the device.
1. 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.
2. The medication delivery device of claim 1 wherein said lock element extends through an aperture in a wall of a socket that defines said plug receiving hollow.
3. The medication delivery device of claim 2 wherein said lock element does not extend within said plug receiving hollow when said dose delivery assembly is not being operated.
4. The medication delivery device of claim 1 wherein said dose delivery assembly comprises a drive member that is shiftable in an axial direction within a barrel of a medication cartridge, and wherein said lock element travels in said axial direction within said plug receiving hollow.
5. The medication delivery device of claim 4 wherein said opening and plug receiving hollow are configured for the plug insertion in a direction generally perpendicular to the axial direction.
