Abstract

A safety syringe includes a barrel, a needle set, a needle set adapter, an engaging element, and a plunger. In this case, the needle set has a needle, and a needle holder. The needle set adapter is connected with one end of the barrel. The needle set adapter has a second through hole. The needle set is disposed at the second through hole and the first through hole and the second through hole are aligned. The engaging element has a first detent portion and at least a second detent portion. The engaging element connects with the needle set adapter. A piston is disposed at one end of the plunger. The piston end has a protrusion portion. When the plunger moves along the first direction to the needle set adapter, the first detent portion and the second detent portion engages the protrusion portion.
