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 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, the control unit (300) is configured to determine a dose or range of the second medicament. Alternatively, the control unit determines or calculates a dose or range of a third medicament. Further, a dispense interface for use with a drug delivery device is disclosed.

Medicament injection device

The purpose of the present invention is to make a medicament injection device easier to use, e.g. by opening a cartridge holder automatically. In order to accomplish said purpose, this medicament injection device is provided with a cartridge holder (7), a main-body case (1), a piston (10), a motor (13), an opening part (130), an open/closed-state detection switch (24), and a control unit (25). The motor (13) drives the piston (10) in either an insertion direction (C) whereby the piston (10) is inserted into a medicament cartridge (9) or a pull-out direction (D) whereby the piston (10) is pulled out of the medicament cartridge (9). In conjunction with the movement of the piston (10) in the pull-out direction (D), the opening part (130) opens the cartridge holder (7). The open/closed-state detection switch (24) detects whether the cartridge holder (7) is open or closed. When the open/closed-state detection switch (24) detects that the cartridge holder (7) has opened, the control unit (25) controls the motor (13) so as to stop the piston (10).

Variable proportion dispenser with cartridge replacement assembly

A variable proportion dispenser (2c) includes a housing (12c) which houses two pharmaceutical cartridges (6b). A reciprocating drive assembly includes drive stems (36c) extending from the pistons (46b) of each cartridge, a limit guide (76c) removably mounted to the housing, and a sliding body (66e, 300) mounted to the housing through the limit guide. Two one-way drivers (326) and threaded dosage adjusters (60c) are carried by the sliding body. Each one-way driver drives the drive stem into the cartridge through a drive surface to provide a range of dose selections. The user can thus control the amount and proportion of each pharmaceutical dispensed during each delivery stroke for each dispensing cycle. The housing is separable from the remainder of the dispenser, preferably using a cartridge release assembly (302), to allow spent cartridge to be replaced. Use of the cartridge release assembly also causes the one-way drivers to release the drive stems to permit the drive stems to be returned to their original positions.
