Problems solved by technology

This problem means that such pre-mixed formulations of multiple active agents may not be suitable as these pre-mixed formulations will have a fixed ratio of active components which cannot be varied by healthcare professionals or users
[0006] Additional problems arise in situations where multi-drug compound therapy is required, as many users cannot cope with having to use more than one drug delivery system or make the necessary accurate calculations of the required dosage combinations

Embodiment Construction

[0055] The present invention delivers a fixed predetermined dose of a secondary drug compound (agent) and a variable dose of a primary or first drug compound through a single output or drug delivery interface. User setting of the dose of the primary medicament automatically determines a fixed dose of the second medicament, which is preferably a single dose contained in a capsule or reservoir with an integral flow dispenser. In a preferred embodiment, the drug delivery interface is a needle cannula (hollow needle). figure 1 An example of a drug delivery device 7 is shown in which the medicated module 4 of our invention (see figure 2 Or 7) Attachment means 9 on the cartridge holder 50 capable of being attached to the distal end 32 . Each medicated module is preferably self-contained and provided as a sealed and sterile disposable with an attachment means compatible with the attachment means 9 of the distal end 32 of the device 7 module. Although not shown, the medicated modu...

Abstract

A medicated module for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle (3). The medicated module does not require the user to manually engage a reservoir (22) containing the secondary medicament. Instead, a biasing member (48) automatically activates the reservoir when the needle guard (42) is retracted. The needle guard prevents accidental needle sticks before and after an injection, and locks after dose delivery.

Description

technical field [0001] The present invention 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 program primed by the user enables a user non-settable dose of the second drug formulation and a variable set dose of the first drug formulation to be delivered to the patient. The pharmaceutical formulations are available in two or more containers, receptacles or packs, each containing individual (single pharmaceutical ingredients) or premixed (multiple pharmaceutical compounds formulated together) pharmaceutical formulations. In particular, our invention relates to a medicated module wherein the user does not have to manually select or program the module to dispense a second drug formulation. Actuation of the needle shield automatically engages the reservoir of the secondary medicament with the dispensing line to ...
