Abstract
An apparatus includes a syringe body and a plunger. The syringe body defines a volume configured to contain a medicament. A proximal end portion of the syringe body includes an engagement portion, and a distal end portion of the syringe body includes a delivery tip. A side wall of the syringe body includes a transparent window. The plunger has a distal end portion configured to move within the volume of the syringe body to convey the medicament. An engagement portion of the plunger is configured to interface with the engagement portion of the syringe body to limit rotation of the plunger about a longitudinal axis of the plunger. An outer surface of the plunger includes a series of indicia, at least one which is visible through the transparent window.

A method of delivering a medicament, comprising:
- inserting a delivery tip of a syringe body into a medicament container, the syringe body defining a volume therein;
- moving a plunger in a proximal direction within the volume of the syringe body to convey a medicament from the medicament container into the volume, the moving performed until a dose indicia from a plurality of dose indicia on the plunger is visible through a transparent window defined by the syringe body, the plunger including an engagement portion configured to interface with an engagement portion of the syringe body to limit rotation of the plunger about a longitudinal axis of the plunger during the moving;
- and
- moving the plunger in a distal direction within the volume of the syringe body to convey the medicament from the volume via the delivery tip.
A kit, comprising:
- a medicament container containing a medicament, the medicament container defining an opening;
- and
- a syringe assembly including a syringe body and a plunger, a proximal end portion of the syringe body including an engagement portion, a distal end portion of the syringe body including a delivery tip configured to be disposed within the medicament container to withdraw the dose of the medicament from the container into a volume defined by the syringe body, a side wall of the syringe body including a transparent window, a distal end portion of the plunger configured to move within the volume of the syringe body to convey the medicament, an engagement portion of the plunger configured to interface with the engagement portion of the syringe body to limit rotation of the plunger about a longitudinal axis of the plunger, an outer surface of the plunger including a plurality of dose indicia, at least one indicia from the plurality of indicia being visible through the transparent window.
