Abstract

An intravenous infusion set and/or blood collection assembly is provided with a safety feature for covering the used needle with a simple movement. The assembly is comprised of a structure which is of very economical and simple construction, which allows for manual mounting, if required, but which may be formed and handled on a mass production line for rapid production, as required. The safety feature is a two-part shield which when placed in cooperating relationship, allows accommodation of a conventional unmodified blood collection needle and body including the usual handling wings. After use, the body with the needle are pulled rearwardly so that the wings do not need to be touched but moved through slots past an abutment into positive locking slots which prevent the body, wings and needle from moving out of the shield thereafter. The two-part shield may be connected by a living hinge and is comprised of a semi-rigid thermoplastic material which gives for passage of the needle body and wings from the use position to the locked position.
