Abstract
Medical needle apparatus for transferring fluid includes syringe assemblies for fluid injection and phlebotomy systems for collecting blood samples. A case with an elongated cavity therein has an open end and a relatively closed end from which a hollow needle projects. An operating member fits through the open end of the case into the cavity and controls both fluid transfer and self-destruction of the apparatus after fluid transfer to prevent reuse. Plastic deformable means responsive to pressure on the operating member in a direction toward the needle renders the apparatus non-reusable after fluid transfer either by actuating needle retraction or by increasing the lateral dimension of the operating member to prevent withdrawal. The apparatus is operable with a single hand to transfer fluid and actuate deformable means without re-positioning the hand on the apparatus.
