Embodiment Construction

[0054] 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 end cap 18 and the distal end 15 of the main body 14 work together to provide a snap fit or form-fitting connection so that once the cover 18 is slid onto the distal end 15 of the main body 14, the frictional fit between the cap and the outer surface 20 of the main body Prevent the cover from accidentally falling from the main body.

[0055] The main body 14 houses a microprocessor control unit, an electromechanical transmission system, and at least two drug reservoirs. When the end cap or cover 18 is removed from the device 10 (e.g. figure 1 (Shown), the dispense interface 200 is mounted to the distal end 15 of the main body 14, and a dose dispenser (for example, a needle assembly) is attached to the interface. The drug delivery device 10 can be used to administer the calculated dose of the...

Abstract

The invention is related to an apparatus comprising: a valve body (300; 400) comprising two inlet openings (302, 304; 402, 404), one outlet opening (306; 406) and a central space (308; 408) connecting the inlet openings (302, 304; 402, 404) and the outlet opening (306; 406), and a spherical element (310; 410) movably contained inside the central space (308; 408) configured for translatory movement and configured to seal either the first inlet opening (302; 402) or the second inlet opening (304; 404), wherein each of the inlet openings (302, 304; 402, 404) are configured for fluid communication with a first reservoir (90) and with a second reservoir (100) and wherein the outlet opening (306; 406) is configured for fluid connection with a septum (352). This apparatus solves the object to make the exchange of used parts including the valve construction less complex. A further object of the invention is to make the exchange easier to handle. The invention is also related to a medical device comprising a dispense interface and an apparatus of the afore-mentioned type.

Description

Technical field [0001] This patent application relates to a medical device that delivers at least two medicaments from separate reservoirs. These agents may include first and second drugs. The medical device includes a dose setting mechanism for automatic delivery or manual delivery of the drug by the user. In particular, the present invention relates to a needle seat and a valve structure for such a needle seat. Background technique [0002] The medicament can be contained in two or more multi-dose reservoirs, containers, or packs, each of which contains an independent (single drug compound) or premixed (co-formulated multiple drug compounds) Medicament. [0003] Certain disease conditions require the use of one or more different drugs to treat. Some pharmaceutical compounds need to be delivered in a specific relationship with each other to deliver the optimal therapeutic dose. This patent application is particularly beneficial in situations where combination therapy is desir...
