Prefilled Autoinjector Combination Device (Three-Step Method)

The prefilled autoinjector combination device primarily consists of three components: the prefilled syringe (PFS), the body assembly, and the drive mechanism. The medication is contained within the prefilled syringe, which is then loaded into the body assembly. The body provides protection for the PFS against accidental damage and features a large viewing window for easy drug inspection. After the body is assembled with the drive mechanism, the injection is powered by an internal spring within the drive mechanism to complete drug delivery.
