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 have 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. The gauge of the needle of a fixed needle syringe could also be ascertained by its color coded needle protective housing. Color coded markings that correspond to the gauge of the needle may also be printed onto the syringe barrel of the fixed needle syringe.
