Embodiment Construction

[0079] figure 1 The illustrated expulsion device in the form of a drug delivery device comprises 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 cooperates with the distal end 15 of the body 14 to provide a snap fit or form fit connection such that once the cover 18 is slid onto the distal end 15 of the body 14, the This friction fit prevents the cover from accidentally falling off the body.

[0080] The main body 14 houses a microprocessor control unit, an electromechanical drive mechanism and at least two medicament reservoirs. When the end cap or cover 18 is removed from the device 10 ( figure 1 When removed, the dispense interface 200 is mounted to the distal end 15 of the body 14 and a dose dispenser (eg a needle assembly) is attached to the interface. Drug delivery device 10 may be used to deliver calculated doses of a second medicament (secondary drug compound) and vari...

Abstract

The present application relates to a dispense interface (500, 600, 700) comprising at least a first flat part (502, 602) tightly connected with a second flat part (504, 604), wherein at least one of the at least two flat parts (502, 504, 602, 604) comprises at least one deepening (508, 510, 512, 513, 608', 608'', 610', 610'', 612', 612'', 613', 613'') configured for forming at least one part of a channel profile (506, 606), wherein the at least one deepening (508, 510, 512, 513, 608', 608'', 610', 610'', 612', 612'', 613', 613'') is formed by embossing, wherein the channel profile (506, 606) comprises at least a first inlet channel (508, 608) and a second inlet channel (510, 610) and at least one outlet channel (512, 612), wherein each of the at least two inlet channels (508, 510, 608, 610) is configured for fluid communication with a respective reservoir (90, 100, 708, 710) of at least two reservoirs (90, 100, 708, 710).

Description

technical field [0001] The present patent application relates to discharge devices, such as medical devices, for delivering at least two liquids, such as liquid pharmaceutical preparations, from separate reservoirs. Such a pharmaceutical formulation may include a first agent and a second agent. The medical device includes a dose setting mechanism for automatic or manual delivery of a pharmaceutical agent by a user. [0002] The medical device may be an injector, such as a hand-held injector, especially a pen injector, which is the type of injector that provides administration by injection of a medicinal product from one or more multi-dose cartridges. In particular, the present invention relates to such user-settable dose syringes. Background technique [0003] A pharmaceutical formulation may be contained in two or more multi-dose reservoirs, containers or packs, each containing individual (single drug compound) or premixed (multiple drug compounds formulated in combinatio...
