Abstract: Automatically-locking syringes are disclosed herein. A syringe in accordance with embodiments of the present technology can include (i) a barrel, (ii) a plunger slidably positioned within the barrel, and (iii) a lock plate coupled to the barrel. The plunger also extends through an opening in the lock plate, and a biasing member is configured to bias the lock plate to a locking position. When the plunger is moved from a depressed position to a withdrawn position, the lock feature engages the lock plate to drive the lock plate away from the locking position to thereby permit the lock feature to pass through the opening in the lock plate. After the lock feature passes through the opening, the biasing member drives the lock plate to the locking position to inhibit movement of the plunger from the withdrawn position to the depressed position.
