Problems solved by technology

This issue means that pre-mixed formulations of multiple active agents may not be suitable as these will have fixed ratios of active ingredients that cannot be changed by healthcare professionals or users
[0006] Additional problems arise where multi-drug combination therapy is required, as many users cannot cope with having to use more than one drug delivery system or necessitate precise calculation of the required dose combination

Embodiment Construction

[0060] Particular embodiments of the disclosed medicated module are capable of administering a fixed predetermined dose of a second pharmaceutical composition (medication agent) and a variable dose of a primary or first pharmaceutical composition through a single output or drug dispense interface. A fixed dose of the second medicament, preferably a single dose contained in a reservoir or sealed capsule, is automatically determined by the user setting the dose of the primary medicament. In a preferred embodiment, the drug dispense interface is a needle cannula (hollow needle). figure 1 An example of a drug delivery device 7 is shown, a medicated module 4 (see figure 2 ) may be attached to the drug delivery device via a connection mechanism 9 arranged at the distal end 32 of the device 7 . Each medicated module 4 is preferably self-contained and provided as a sealed and sterile disposable module having an attachment mechanism 8 compatible with the attachment mechanism 9 at the...

Abstract

A reservoir (31) with at least one flexible section for use in a medicated module (4) for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device (7) containing a first medicament accepts a medicated module (4) containing a single dose of a second medicament (2) and where both medicaments are delivered through a single hollow needle (3). The reservoir (31) comprises one or more slit valves (44, 45) to allow for delivery of the first and second medicaments. The medicated module (4) also contains a needle guard (22) that engages a housing (43) of the reservoir (31) to open the slit valves (44, 45).

Description

technical field [0001] Particular embodiments of the present disclosure relate to medical devices and methods for delivering at least two pharmaceutical agents from separate reservoirs using a device having only a single dose setting mechanism and a single dispense interface. A single delivery program initiated by the user results in delivery to the patient of a preferred non-user-settable dose of the second pharmaceutical agent and a preferred variable set dose of the first pharmaceutical agent. The pharmaceutical agent may be available in two or more reservoirs, containers or packages each containing separate (single drug composition) or premixed (mixed multiple drug composition) drug agent. In particular, the present disclosure relates to flexible reservoirs containing single doses of a second medicament. The reservoir may be used in a medicated module attachable to the primary drug delivery device. At least one slit valve, in particular a "humpback" type valve, may allow...
