Embodiment Construction

[0047] figure 1 The drug delivery device shown in 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. The end cap 18 and the distal end 15 of the 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 body 14, the friction fit between the cap and the body outer surface 20 prevents the cap from Accidentally detached from the main body.

[0048] The main body 14 contains a microprocessor control unit, an electromechanical drive train and a single holder for holding a medicament reservoir or cartridge. When removing the end cap or cover 18 from the device 10 (as figure 1 ), a dispense interface 201 is mounted to the distal end 15 of the body 14, and a dose dispenser (eg, a needle assembly) is attached to the interface. Dispense interface 201 provides fluid communication between the needle assembly and a medicament r...

Abstract

A medicament delivery device (10) for the administration of one or more drug agents is described. The device (10) has a priming mode (920, 945) and a drug delivery mode (947) for administering delivery of the drug agents. The device includes a controller (700) operative for controlling the device (10) to perform a priming operation, and a user interface (74) for activation of the priming operation. The controller (700) is operative to perform the priming operation by way of a plurality of intermittent doses of medicament, the number of intermittent doses being dependent on the activation of the user interface (74).

Description

technical field [0001] The present invention relates to a drug delivery device, and a method of controlling the device for administering one or more drug agents to a patient, especially but not exclusively for self-administration of the drug agent(s). Background technique [0002] Certain disease states require treatment with one or more different agents. Some pharmaceutical compositions need to be delivered in a specific relationship to each other in order to deliver an optimal therapeutic dose. Although this patent application is applicable to single agent devices, it is beneficial where combination therapy is desired but not possible in a single formulation for reasons such as, but not limited to, stability, therapeutic Reduced efficacy and toxicology. [0003] For example, in some cases it may be beneficial to use long-acting insulin (which may also be referred to as the first or primary agent) together with glucagon-like peptide 1 (also referred to as as a second dru...
