ABSTRACT:
A modular safety needle cannula device that can be stored independently from the syringe that it will be used with, wherein when it is to be used the modular safety needle cannula device is attached or fixed to a suitable syringe, used to inject medicament into a body and than the used needle cannula is suitably disposed into an elongated module wherein the needle cannula cannot prick or harm a person. The device is comprised of a hub that is used to attach the device to a standard syringe, a capsule, a slideable piston, a compressed biased spring, a needle cannula that is straight and rigid on the first end and curved or flexible between the first end and the second end and wherein the second end of the needle cannula is fixed to the hub. A trigger or release means holds the slideable piston near the first end of the elongated capsule. After the needle cannula has been used to inject medicament into the body, the trigger or release meanes is pressed, releasing the slideable piston and thereby allowing the compressed spring to thrust the slideable piston toward the second end of the needle cannula thereby crushing the curved and flexible section of the needle cannula between the slideable piston and the second end of the elongated capsule thereby destroying the needle cannula and further encapsulating the point at the first end of the needle cannula in the inside of the elongated capsule thereby preventing an accidental needle prick or injury from the point or the first end of the needle cannula.
