Embodiment Construction

[0059] 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. The distal end 15 of the main body 14 and this end cap 18 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, the distance between the cap and the outer surface 20 of the main body This friction fit prevents the cover from inadvertently falling off the body.

[0060] The main body 14 houses: a microprocessor control unit, an electromechanical drive train, and at least two medicament reservoirs. When the end cap or cover 18 is removed from the device 10 (as figure 1 ), the dispense interface 200 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. Drug delivery device 10 may be used to administer a calculated dose of a second medicam...

Abstract

The technical problem of providing a channel which is more reliable and protected against contamination by the guided liquid and which can be produced in an easy and cost-effective manner is thus solved by a device. The apparatus comprises: a plastic part (316), and a channel (314) within the plastic part configured to guide at least one fluid, wherein the channel is configured for use in a medical device, wherein the channel is A Y-shaped channel with three ends (324, 326, 328), and wherein the channel is created using gas injection techniques and / or water injection techniques. This technical problem is further solved by a method for producing at least a part of a medical device, said method comprising the steps of producing a Y-shaped channel in a plastic part using gas injection techniques and / or water injection techniques, and The Y-shaped channel opens to create at least one opening.

Description

technical field [0001] This patent application relates to medical devices that deliver at least two pharmaceutical agents from separate reservoirs. Such a pharmaceutical formulation may include a first and a second agent. The medical device includes a dose setting mechanism for manually or automatically delivering the drug by a user. Background technique [0002] The drug formulations may be contained in two or more multi-dose reservoirs, containers or packages, each containing separate (single drug compound) or premixed (co-formulated multiple drug compounds) drug formulations. [0003] 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. This patent application has particular benefits where combination therapy is desired, but not possible in a single formulation, due to, for example but not limited to, compr...
