MEDICATED MODULE WITH AUTOMATIC RESERVOIR ENGAGEMENT AND TRIGGER LOCK MECHANISM

摘要

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. The medicated module does not require the user to manually engage a reservoir containing the secondary medicament. Instead, a biasing member automatically activates the reservoir when the needle guard is retracted. The needle guard prevents accidental needle sticks before and after an injection, and locks after dose delivery. A biasing member is provided within the medicated module that may be in a first, trigger-locked position within a secondary packaging, and a second, triggerable position when removed from the secondary packaging to prevent accidental triggering of the device prior to removal from its packaging by the user at the point of use.
