MEDICATED MODULE WITH DEFORMABLE MEMBRANE

摘要

A method and system for sequentially dispensing a non-user settable dose of one medicament followed by a user-settable dose of a primary medicament. A medicated module may be attachable to a drug delivery device and the drug delivery device may have a drug reservoir holding a first medicament. The medicated module includes a first needle, a second needle, a deformable membrane, and a second medicament. The deformable membrane facilitates sequential dosing of the second medicament followed by the first medicament. After the medicated module is attached to the drug delivery device, (i) the first needle is in fluid communication with the drug reservoir and (ii) the deformable membrane prevents fluid communication between the first and second needle. The deformable membrane prevents fluid communication between the first and second needle until substantially all of the second medicament is dispensed.
