An expanding plunger rod () for a syringe (). The expanding plunger rod is configured to transition from a packaged configuration for packaging to an expanded configuration for operation. The expanding plunger rod comprises a substantially cylindrical outer sleeve () having a closed-off bottom end () and an open upper end (). The expanding plunger includes an inner rod () having a lower end () and an upper end (). The inner rod is slidably disposed coaxially within the outer sleeve. In the packaged configuration, the inner rod is nested within the outer sleeve. In the expanded configuration, the inner rod is disposed substantially axially above the outer sleeve, and the inner rod is configured to lock axially in place so as to prevent transition from the expanded configuration to the packaged configuration.
