Abstract

A medication delivery device included molded cylindrical barrel having visual marks on the surface of the barrel in the axial direction, a plunger seals the distal opening of the cylindrical barrel, a molded needle hub disposed in the proximal opening of the cylindrical barrel for sealing the needle hub to the barrel. A needle is disposed in the needle hub for communicating liquids by operation of the plunger in the axial direction. The circumferential surface on the flange of the needle hub comprises a colored mark that corresponds to a characteristic of the medication delivery device or its contents.

Claims

1. A method of using a medication delivery device, comprising:

identifying a medication delivery device based on a single colored mark on an exterior of the medication delivery device packaging, wherein the medication delivery device includes;

a barrel with a needle hub disposed at a first end of the barrel, the needle hub having a flange disposed thereon, the flange having a single colored mark with a color matching a color of the single colored mark on the exterior of the medication delivery device packaging; and

a needle safety shield removably attachable to the needle hub;

wherein when the needle safety shield is attached to the needle hub, the needle safety shield abuts the flange of the needle hub; and

wherein the flange is completely visible to a user when the needle safety shield is not attached to the needle hub;

identifying a container of insulin, the insulin container having a cap for receiving the medication delivery device to communicate insulin into the medication delivery device, wherein the cap includes a visual mark having a single color matching the color of the single colored mark on the medication delivery device;

piercing the cap of the insulin container with the medication delivery device and withdrawing a prescribed amount of insulin by identifying insulin units disposed on a surface of the medication delivery device; and

injecting the insulin into a patient.

2. The method as recited in claim 1, wherein the single colored mark on the medication delivery device corresponds to a concentration of insulin.
