Problems solved by technology

This problem means that pre-mixed formulations (formulations) with multiple active agents may not be suitable, because these pre-mixed formulations will have a fixed ratio of active components, the fixed ratio cannot be used by medical personnel 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

[0075] Particular embodiments of the disclosed medicated module and drug delivery system enable the administration of a fixed predetermined dose of a secondary drug compound (agent) and a variable dose of a primary or primary drug compound through a single output or drug dispense interface. The dose of the primary medicament may be set by the user independently of a single dose of the second medicament, preferably contained in a reservoir of a medicated module attachable to the drug delivery device.

[0076] In a preferred embodiment, the drug delivery interface is a needle cannula (hollow needle). figure 1 One example of a drug delivery device 100 is shown, a medicated module 200 (see Figure 2 to Figure 15 ) attachable to the connection means 109 of the distal end 132 of the drug delivery device 100. Each medicated module 200 is preferably self-contained and provided as a sealed and sterile disposable with a feature compatible with the attachment means 109 at the distal en...

Abstract

A medicated module for an injection system to co-deliver at least two medicaments is disclosed. The drug delivery device includes a push rod operably connected to a dose dial button. The medicated module includes a housing having a connector configured for attachment to the drug delivery device, and the housing is configured to receive a portion of the push rod when the medicated module is attached to the drug delivery device. The medicated module further includes a reservoir in the housing comprising a single dose of a medicament and a needle guard operably connected to the housing and configured to move in an axial direction during application to an injection site. Still further, the medicated module includes a sleeve in the housing configured to move axially in the housing and a locking collar in the housing configured to move axially and rotationally in the housing.

Description

technical field [0001] Particular embodiments of the present disclosure relate to medical devices and methods of delivering at least two drug formulations from separate reservoirs using devices having only a single dose setting mechanism and a single dispense interface. A user-non-settable dose of the second medicament and a variably settable dose of the first medicament may be delivered to the patient in a single, user-initiated delivery step. The pharmaceutical formulations may be available in two or more reservoirs, containers or packages, each containing separate (single pharmaceutical compound) or premixed (multiple pharmaceutical compounds formulated together) pharmaceutical formulations. In particular, embodiments of the present disclosure relate to a medicated module having a needle shield that latches after a predetermined number of doses have been delivered. Thereby, undesired reuse of the medicated module can be prevented. Background technique [0002] Some dise...
