Abstract: A needle dispenser includes a hopper configured to receive and hold a plurality of bulk needles for dispensing. A singularizing drum is positioned to rotate with a portion of the singularizing drum exposed to the interior of the hopper. The singularizing drum includes at least one groove in an outer surface of the singularizing drum. A positioning drum positioned to rotate adjacent to the singularizing drum. The positioning drum includes at least one groove in an outer surface of the positioning drum. The singularizing drum and the positioning drum rotate in coordination to pass a needle from the at least one groove of the singularizing drum to the at least one groove of the positioning drum.

Abstract: A protective dental needle includes a sheath having a cylindrical body with a channel along the cylindrical body. A needle assembly includes a hypodermic needle extending through a hub. The needle assembly is retained within the sheath and movable within the sheath between a retracted position and an extended position. A needle cap is positioned external to the sheath. The needle cap includes a plurality of longitudinal ribs that extend from an interior surface of the needle cap.

Abstract: A protective cover for a syringe needle includes a sheath and a needle hub. The sheath preferably includes a cylindrical body terminated with a bullet shaped end. The needle hub includes a needle base and a hypodermic needle retained in the needle base. The needle base includes a bullet shape and a locking projection extending from an outer perimeter of the needle base. A lengthwise slot is formed through the cylindrical body. The lengthwise slot receives a button portion of the locking projection. A retracted locking notch is formed on one end of the extension slot. An extended locking notch is formed on an opposing end of the lengthwise slot. The button portion is retained in the retracted locking notch or the extended locking notch. A second embodiment of the protective cover includes a sheath and a needle hub. The needle hub is slidably retained in the sheath.

The needle base includes a bullet shape and a locking projection extending from an outer perimeter of the needle base. A lengthwise slot is formed through the cylindrical body. The lengthwise slot is sized to receive a button portion of the locking projection. A retracted locking notch is formed on one end of the extension slot. An extended locking notch is formed on an opposing end of the lengthwise slot. A storage notch is formed adjacent the retracted locking notch. The button portion is retained in the retracted locking notch, the extended locking notch or the storage notch.
