Immunoject is a novel, low cost prefilled syringe that is simple and intuitive to use. By design, it eliminates many of the prevalent errors encountered with vials.

Immunoject allows for single handed operation, leaving one hand free to clean the injection site or support the patient. In Immunoject, the ARCH package is combined with a foldable backing that consists of two joined panels. For injection, one of the panels is folded over to expose the needle, and to depress the ARCH package between the panels to deliver the dose. At the end of the injection the panels are turned in an opposite direction to bend the needle and protect it, thereby disabling the device from being reused, and making it safe to discard.

The low parts count and parts simplicity makes Immunoject simplest and list expensive prefilled syringe for mass manufacturing.
