Abstract
Disclosed is a hypodermic syringe with several embodiments teaching the safe disposal of the cannula and hub of the syringe into a container such as a SHARPS CONTAINER without the need of replacing the needle cover thus eliminating the very real danger of an accidental stick of a finger or hand of the technician with a contaminated needle. The preferred embodiment allows the plunger to stop at a first resistance and when the needle is removed from the subject and placed over the disposal container, continued forward motion forces the hub and needle to separate from the barrel thus involving the use of only one hand and eliminating the need to bring the others hand anywhere near the contaminated needle.
