Insulin Syringe

To administer Insulin properly, familiarize yourself with information about insulin: (a) insulin syringes, (b) storage, (c) site selection (d) steps for injection, and rotation, (e) Preservation of insulin.

First you learn about simple syringe. The word syringe is derived from Greek word syrinx.

A syringe is a simple piston pump consisting of a plunger that fits tightly in a tube. The plunger can be pulled and pushed along inside a cylindrical tube (the barrel), allowing the syringe to take in and expel a  liquid or gas through an orifice at the open end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle, to help direct the flow into and out of the barrel. Syringes are often used to administer  injections.

Technically, the syringe is actually only the portion that holds the medication and the plunger which draws in the medication and then expels it through the needle. Needle refers to only the needle at the end of the Syringe, the sharp part. The diameter of needles on insulin syringes are measured in Gauges.
