Only-Once Syringe / Syringe

Only-Once Syringe

I do some little changes on the disposable syringe to make it have to be destroyed after the first use. I cut out of a groove on the head of the core rod which is near the piston. After the syringe is used, people just need to twist the core rod to break off it, thus the second use of disposable syringes can be avoided.
