Abstract: A safety needle assembly has a collar or ring that is rotatably mounted to a needle hub. The needle assembly may be connected to a syringe by the user grasping the needle hub in first and second embodiments, or turning of the needle sheath in other embodiments. The collar of the needle assembly may be rotated by turning the needle sheath. The needle hub may also interact with the collar by rotating the needle sheath. Mechanisms are provided at both the collar and the housing so that once the contaminated needle is covered, the needle assembly may be removed from the syringe for disposal by rotating the needle housing.

Abstract: A safety needle assembly has a needle hub and a collar. Integrally formed from the proximal portion of the needle hub is a ring that surrounds its luer base. At the distal portion of the needle hub there are coaxially formed circumferential flanges which act to allow the collar to be rotatable 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. Before use, the needle extending from the needle hub is covered by a needle sheath that has a groove formed circumferentially at its proximal end that snap-fits to a circumferential rib formed at the distal end of the collar.

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.

Abstract: A needle protection assembly has a needle hub with a proximal portion having two sets of spaced flanges and a distal portion having a number of arms for forming at least one catch and one slot. A collar with a needle protection housing has at its inner surface a number of protrusions fittable within the space defined by the two sets of flanges, when the collar is press-fitted to the needle hub, and a number of fingers that removably grasp a needle sheath that covers the needle extending from the needle hub. After the sheath is removed, the needle protection housing may be pivoted to cover the needle. Once the housing fully covers the needle, a spline inside the housing coacts against the catch at the needle hub to enable the needle hub to be removed from a syringe by rotating the housing.

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 needle protection assembly has a needle hub with a proximal portion and a distal portion. Two sets of spaced apart flanges extend transversely from the proximal portion of the needle hub. A number of arms extend transversely from the distal portion of the needle hub for forming at least one catch and at least one slot. A collar to which a needle protection housing is attached has a proximal end and a distal end. The proximal end of the collar has, at its inner surface, a number of protrusions that are fitted within the space defined by the two sets of flanges, when the collar is press-fitted to the needle hub. The distal end of the collar has a number of fingers or retainers that are used to grasp and removably couple a needle sheath. The needle sheath covers the needle that extends from the distal end of the needle hub before use.

Abstract: A collar to which a needle protection housing is attached has a proximal end and a distal end. The proximal end of the collar has a number of internal protrusions that are fitted within the space defined by the two sets of flanges extending from the proximal portion of a needle hub. The distal end of the collar has a number of fingers or retainers that are used to grasp and removably couple a needle sheath. The needle sheath covers the needle that extends from the distal end of the needle hub before use. A needle protection housing is pivotally connected to the collar, and is pivoted to cover the needle after use. A channel or opening in the protective housing through which the needle passes is formed by a pair of progressively angled lips that extend longitudinally along the length of the housing.

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.
