Embodiment Construction

[0055] According to a particular embodiment, the present invention administers a fixed predetermined dose of a second medicament (secondary drug compound) and possibly a variable dose of a first medicament (primary drug compound) through a single output or a single drug dispense interface (e.g. a double-ended needle). ). The user's setting of the dose of the primary medicament can automatically determine the fixed dose of the second medicament. The fixed dose of the second medicament is preferably a single dose. In a preferred arrangement, the drug dispense interface comprises a needle cannula (hollow needle) which can be locked after injection of the medicament and a needle shield which can be locked after injection. More preferably, the invention allows the user to prime the injection needle with the first medicament contained in the drug delivery device.

[0056] figure 1 A preferred arrangement of the medicated administration module 10 including the bypass member 52 is ...

Abstract

A medicated module attachable to a drug delivery device comprises a connecting body configured for attachment to the drug delivery device. A first needle is fixed within the connecting body and a movable needle hub is operatively coupled to the connecting body. A needle guard is operatively coupled to the connecting body and a biasing member is positioned between the connecting body and needle guard. A second needle is fixed within the needle hub. A first cavity within the connecting body defines a reservoir containing at least one dose of a medicament. The reservoir configured for fluid communication with the first and the second needle. The reservoir comprises a bypass configured to allow medicament from the drug delivery device to bypass the reservoir and exit the second needle.

Description

technical field [0001] According to a preferred embodiment, the present disclosure relates to medical devices and methods for delivering at least two drug formulations from separate reservoirs using a device having only a single dose setting mechanism and a single dispense interface. A single delivery step initiated by the user results in a non-user settable dose of the second drug formulation and a variable set dose of the first drug formulation being delivered to the patient. Pharmaceutical formulations are available in two or more reservoirs, containers or packages, either separate (single drug compound) or premixed (multiple drug compounds formulated synergistically). One aspect of the present invention is of particular benefit, through the control and definition of the treatment curve, the optimization of the treatment response for a specific target patient population can be optimized. Background technique [0002] Certain disease states require treatment with one or m...
