ABSTRACT:
An apparatus is provided for safely and conveniently holding and dispensing needle assemblies. The apparatus includes a generally tubular holder with opposed dispensing and inserting ends and an elongate passageway extending therebetween. The tubular holder is dimensioned to slidably receive needle assemblies therein in axial alignment with one another. Separator disks are disposed between adjacent needle assemblies in the holder, and an end disk is disposed between the inserting end of the holder and the needle assembly adjacent thereto. The separator disks and the end disk are color coded to be readily visible through a window in the holder. The needle assembly nearest the dispensing end can be mounted to medication delivery pen or other hypodermic syringe and may be removed from the holder. The used needle assembly may then be inserted into the inserting end of the holder. This process is repeated for each administration of medication until the supply of needles is exhausted. The number of needle assemblies remaining can be readily observed through the window by tracking the incremental advancement of color coded separator disks.
