Abstract

Methods and systems for an injection system are provided. An example injection system includes a container for a pharmaceutical that is sealed at a proximal end with a plunger having a pushing surface for engaging an inner surface of the hollow body. A plunger rod extends axially from the proximal end of the container and is covered with a plunger rod cover. Removal of the cover activates the system and allows for delivery of the pharmaceutical product from the container by advancing the plunger within the container towards the seal.
