Embodiment Construction

[0042] figure 1 The drug delivery device shown includes a body 14 extending from a proximal end 16 to a distal end 15 . At the distal end 15, a removable end cap or cover 18 is provided. This end cap 18 and the distal end 15 of the main body 14 work together to provide a snap fit or form fit connection so that once the cover 18 is slid onto the distal end 15 of the main body 14, this frictional fit between the cap and the main body outer surface 20 prevents The cover is unintentionally dropped from the main body.

[0043] The main body 14 houses a microprocessor control unit, an electromechanical drive train, and a single holder for holding a medicament reservoir or cartridge. When the end cap or cover 18 is removed from the device 10 (as figure 1 ), a dispense interface 201 is mounted to the distal end 15 of the main body 14, and a dose dispenser (eg a needle assembly) is attached to the interface. Dispensing interface 201 provides fluid communication between the needle a...

Abstract

A medicament delivery device is shown for the administration of one or more drug agents. The device comprises a medicament cartridge retainer for holding a medicament cartridge. A dispense interface can be attached to an attachment of the device for facilitating fluidic communication from the device. Further, an interface sensor is configured to provide an output indicative of whether the dispense interface is attached to the attachment. The device also comprises a piston rod for driving a bung of the medicament cartridge, and a drive train for advancing the piston rod to the bung. A controller is configured to control the drive train to advance the piston rod towards the bung when the output of the interface sensor indicates that the dispense interface is not on the attachment. The controller is further configured to disable advancement of the piston rod when the output of the interface sensor indicates that the dispense interface is at least partially on the attachment.

Description

technical field [0001] The present invention relates to a drug delivery device for administering one or more drug agents to a patient, and particularly but not exclusively for self-administration of said drug agents, and a method of controlling the device. Background technique [0002] Certain disease states require treatment with one or more different agents. In order to deliver an optimal therapeutic dose, some pharmaceutical compounds need to be delivered in a specific relationship to each other. While this patent application is applicable to single drug devices, there are benefits where combination therapy is desired, which is not possible with a single formulation due to reasons such as but not limited to stability, compromised therapeutic properties and toxicology . [0003] For example, in some cases, long-acting insulin (also referred to as the primary or primary agent) is used along with glucagon-like peptide-1 such as GLP-1 or a GLP-1 analog (also referred to as ...
