Abstract
A computerized electro-mechanical drug delivery device (10) configured to deliver at least one dose of two or more medicaments. The device comprises a control unit (300). An electro-mechanical drive unit (500, 600) is operably coupled to the control unit and a primary reservoir (90) for a first medicament and a secondary reservoir (100) for a fluid agent, e.g. a second medicament. An operator interface (60) is in communication with the control unit (300). A single dispense assembly (200) is configured for fluid communication with the primary (90) and the secondary (100) reservoir. Activation of the operator panel sets a first dose from the primary reservoir and based on the first dose and a therapeutic dose profile (860), the control unit (300) is configured to determine a dose or range of the fluid agent. Alternatively, the control unit determines or calculates a dose or range of a third medicament.

17. An injection device comprising:
-
a primary reservoir of primary medicament containing multiple doses; a secondary reservoir containing multiple doses of a fluid agent that is different than the primary medicament; an electro-mechanical drive system operatively engaged with both the primary reservoir and the secondary reservoir; a single dispense assembly in fluid communication simultaneously with the primary reservoir and the secondary reservoir; a predetermined therapeutic dose profile stored in memory of the injection device that correlates doses of the primary medicament with doses of the fluid agent; and a control unit operably coupled to the electro-mechanical drive system and a human interface, where the control unit, receives a set dose value of the primary medicament entered through the human interface, determines a single dose of the fluid agent based on a comparison of the set dose value with the therapeutic dose profile, and activates the electro-mechanical drive system to expel the set dose of the primary medicament and the single dose of the fluid agent through the single dispense assembly. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of operating an injection device comprising:
-
receiving into memory of the injection device a predetermined therapeutic dose profile that correlates doses of a primary medicament with doses of a fluid agent, where the fluid agent is different than the primary medicament; receiving at a control unit located in an injection device a set dose value of the primary medicament entered through a human interface located on the injection device; determining at the control unit a single dose of the fluid agent based on a comparison of the set dose value with the therapeutic dose profile; and activating an electro-mechanical drive system through the control unit to expel the set dose of the primary medicament and the single dose of the fluid agent through a single dispense assembly. - View Dependent Claims (29, 30, 31)
