ABSTRACT:
A syringe tip device and method wherein a safety chamber is provided at the end of the hub for a slip tip, eccentric tip, or threaded tip syringe. The hub is placed on any conventional syringe in a convention manner; the safety sheath protecting the needle cannula is removed and the syringe is filled with the desired amount of medication wherein the medication is injected into a patient wherein when the process is complete, a button or lever is depressed, releasing an internal biased spring that strikes the needle cannula and bends the needle cannula within the hub chamber until the entire needle cannula is bent and destroyed within the hub chamber thus rendering the needle cannula safe from an accidental needle cannula prick.
