Needle protection device with gauge specific color coding and method for manufacturing thereof

摘要

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.

1. A needle syringe device, comprising: a syringe barrel body that includes a distal portion having a needle hub with a distal end wherefrom a needle of a particular gauge fixedly extends so that the needle is not removable from the syringe barrel body, a needle protection housing having a slot formed substantially along its body pivotable relative to said syringe barrel body, said needle having a longitudinal axis and being covered by a sheath frictionally held to the needle hub at the distal portion prior to use and is ready for use with the removal of said sheath, the sheath being made of either a translucent or clear plastic material, said needle adapted to be covered by said housing after the removal of said sheath when said housing is pivoted relative to the distal portion from a position away from the syringe barrel body to a position in alignment along the longitudinal axis of said needle, said needle passing through the slot formed along said housing when said housing is pivoted to the position to cover said needle, said housing formed from a plastics material having a specific color preassigned to correspond to said particular gauge of said needle according to a standard so that the gauge of the needle of said syringe is ascertainable by the color of said housing prior to and after the removal of said sheath to expose said needle, the needle hub having the same specific color, wherein a user is able to determine the particular gauge of the needle through the sheath without removal of the sheath because the sheath is made of the translucent or clear plastic material.
