Abstract: To enable a user to readily determine the gauge of the needle of a needle assembly that has a base and a needle protective housing pivotably attached thereto, the needle assembly is injection molded from a color coded molding material which color was preassigned to correspond to the gauge of the needle. As a result, both the base and the protective housing of the needle assembly are the same specific color, and reflect or provide an indication of the given gauge of the needle. The needle sheath that covers the needle prior to use may be made of a plastics material that may be clear, or have the same or a different color than that of the needle assembly.

Abstract: A safety needle assembly has a needle hub having a proximal portion and a distal portion. Integrally formed from the proximal portion is a ring that surrounds the luer base portion of the needle hub. Windows are provided at the sidewall of the ring to enable a user to see the base portion of the needle hub. At the distal portion of the needle hub there are coaxially formed circumferential flanges. The space between the flanges and the end wall of the ring surrounding the luer end of the needle hub is dimensioned to accept protrusions at the inner surface of the proximal portion of a collar. Once mated to the space at the needle hub, the collar is rotatable, although not freely, about the needle hub. A needle protection housing is connected to the collar and is pivotable to cover the needle that extends from the distal end of the needle hub.

Abstract: A safety needle assembly has a collar or ring that is rotatably mounted to a needle hub, which may be connected to a medical device such as a syringe. The needle assembly may be connected to the syringe by the user grasping the needle hub in first and second embodiments, or turning of the needle sheath in other embodiments. In all of the embodiments, the collar of the needle assembly may be rotated by turning the needle sheath, which is designed to interact with the collar. In some of the embodiments, the needle hub likewise interacts with the collar in such a way that by rotating the needle sheath, the needle hub is likewise rotated for connection to a syringe. When an exposed needle is to be covered, after the needle sheath has been removed, a housing connected to the collar is pivotally moved to cover the needle.
