Abstract
A one-handed hypodermic syringe is a renovated structure that allows users to push and pull the syringe by one hand. The medical personnel may place their thumbs inside the ring disposed in the distal end of the plunger and may press the concave objects disposed in the distal end of the barrel by their index fingers and middle fingers. Thus, the syringe may be held steadily, and the pull-push action of the injection manipulated with one band. The convenience for the medical personnel's use of hypodermic syringe is thereby enhanced.
