Methods and systems for a cartridge assembly for use with an injection system are provided. An example cartridge assembly may include an ampule containing a pharmaceutical product that is sealed at a distal end with a pierceable diaphragm. The cartridge assembly may also include a hub comprising a proximal portion defining a cavity that is configured to engage the distal end of the ampule and a piercing member positioned within the cavity. The piercing member may include a fluid pathway between a proximal end portion comprising an opening and a distal end in fluid communication with a distal opening of the hub. The proximal end portion may engage the pierceable diaphragm, and the piercing member may apply a force to the pierceable diaphragm in the inactivated position without penetrating the pierceable diaphragm.

Cartridge assembly for an injection system

An injector device for a pharmaceutical cartridge. The injector device includes a body defining a space for receiving a pharmaceutical cartridge. One or more retention members are disposed on the outer surface of the body. The injector device further includes a plunger rod having a connection member constructed for connection to a piston associated with a cartridge. The plunger rod has one or more receiving members. constructed to cooperatively retain the plunger rod on the body in a first position, and to release the plunger rod from the body when the plunger rod is moved to a second position. The plunger rod further includes a surface for engaging a pharmaceutical cartridge positioned within the body of said injector and for moving a pharmaceutical cartridge distally as the plunger rod is moved from its first position to its second position. A tamper evident band is secured to plunger rod and injector body.
