The present invention relates to a syringe that prevents reuse and more specifically to a syringe formed with a needle (10), a cylinder (20) wherein an injection solution is stored, a plunger (30) that sucks the injection solution into the cylinder (20) or pushes it through the needle (10), and a piston (40) that couples with the plunger (30) at its tip to maintain sealing; wherein the end part of the needle (10) is formed to protrude inside of the cylinder (20) and when the plunger (30) is pushed, the end part of the needle (10) that has protruded into the cylinder (20) passes through the piston (40) and a part of the piston (40) is cut off and fitted into the needle (10) so that the pathway for discharging the injection solution is blocked, and when the injection solution has been injected entirely, the end part of the needle protruding into the cylinder cuts off a part of the piston and passes through the piston, so the cut area is received inside the needle to block the pathway for discharging the injection solution to prevent reuse. |
