Problems solved by technology

This problem means that pre-mixed formulations with multiple active agents may not be suitable because these pre-mixed formulations will have a fixed ratio of active components that cannot be used by healthcare professionals or change
[0006] Another problem is that when multiple drug compound treatments are required, many users cannot cope with having to use more than one drug delivery system or having to precisely dose the desired combination of doses

Embodiment Construction

[0059] Specific embodiments of the disclosed medicated module and drug delivery system enable delivery of fixed and predetermined doses of a secondary drug compound (agent) and variable doses of a primary or primary drug compound via a single output or drug delivery interface . By setting the dose of the primary medicament by the user, a fixed dose of the second medicament, preferably a single dose contained in a reservoir or a sealed capsule, is automatically determined. 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, a medicated module 4 (see Figure 2-5) attachable to the connection mechanism 9 of the distal end 32 of the drug delivery device 7 . Each medicated module 4 is preferably self-contained and provided as a sealed and sterile disposable module with an attachment mechanism 8 at the distal end 32 of the device 7. The attachment mechanism 9 is compatible. Although...

Abstract

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 primary medicament accepts a medicated module (4) containing a single dose of a secondary medicament and where both medicaments are delivered through a single hollow needle (3). The medicated module (4) is configured so that it will first deliver both the primary and secondary medicaments and then, if needed, a dose(s) of additional primary medicament. The module (4) also contains a needle guard (22) that locks the first dose delivery, but can be manually overridden by a user to perform a second or subsequent injection of primary medicament.

Description

technical field [0001] Particular embodiments of the present disclosure relate to medical devices and methods for delivering at least two drug agents from separate reservoirs utilizing a device having only a single dose setting mechanism and a single dispense interface. A single delivery program initiated by the user may deliver a non-user settable dose of the second drug formulation and a variably settable dose of the first drug formulation to the patient. The drug formulations are available in two or more reservoirs, containers or packages, each containing a separate (single drug compound) or premixed (co-formulated multiple drug compounds) drug formulation. In particular, the present disclosure relates to a medicated module wherein, following delivery of a first dose, the user has the option to consciously unlock the module to perform a second dose delivery of a first medicament. This may be particularly advantageous in some cases where the therapeutic response for a parti...
