Abstract
A needle removal/destruction apparatus for pulling a metal needle free from a plastic hypodermic syringe, while also deforming the metal needle to prevent reuse thereof. The apparatus includes a container having a rotatable needle removing fixture mounted therein. A metal needle hypodermic syringe is inserted within the rotatable needle removing fixture, which is thereafter rotated to pull the needle free of the needle hub while also permanently deforming the needle to prevent subsequent reuse thereof.
Claims19
An apparatus for removing a needle from a medical device, comprising:
- a container defining a chamber, said container including a container top having an aperture communicating with said chamber;
- a needle removing fixture rotatably mounted to said container top and rotatable with respect thereto free of shearing surfaces, said needle removing fixture being positioned at least partially within said chamber and including a passage for receiving a needle extending through said aperture in said container top;
- and
- a handle coupled to said needle removing fixture for rotating said needle removing fixture.
A method of removing a needle from a medical device, comprising:
- inserting said needle of said medical device into a passage of a needle removing fixture, wherein said needle removing fixture is rotatably mounted to a top of a container, and
- rotating said needle removing fixture about an axis via a handle while maintaining said medical device in a substantially stationary position, thereby removing said needle from said medical device without shearing thereof.
A method of removing a metal needle from a plastic hub of a medical device, comprising:
- securing said medical device in a substantially stationary position whereby said needle is located at a predetermined position;
- disconnecting said metal needle from said plastic hub without shearing of said needle by rotating said needle in a needle removal fixture that is rotatably mounted to a container, wherein said needle is deformed to prevent reuse thereof.
