Abstract
A syringe assembly and methods of producing the syringe assembly are described. The syringe assembly may include a syringe body, a plunger rod, a barrel cover, and a tamper evident device. The syringe body has a chamber configured to receive a material. The plunger rod moves within the chamber to dispense the material. The barrel cover covers the syringe body. The backstop is attached to the barrel cover to prevent a portion of the plunger rod from moving proximally through the backstop. The tamper evident device includes a tamper evident cap covering a distal portion of the syringe body, a collar attached to the barrel cover, and a frangible connection between the tamper evident cap and the collar.
