Abstract

Automatic injection device includes a housing, a syringe, a plunger, and a syringe carrier. The housing includes a barrel between a first end and a second end. The barrel includes an elongated window to allow viewing of contents inside the housing. The syringe is disposed within the housing and has a reservoir. The plunger is at least partially disposed within the syringe and includes a visual indicator. The syringe carrier is disposed within the housing and configured to contain the syringe and displace the syringe within the housing between a first position and a second position. The syringe carrier can be substantially transparent. The syringe carrier can have first and second legs and an extension disposed therebetween, and at least a portion of the extension can be configured to align with the window and the reservoir when the syringe carrier is in the first position.
