Parts of the Insulin Syringe
In order to properly care for your health, it is vital that you understand the tools required to administer insulin. There are three main parts of an insulin syringe: the needle, barrel, and plunger. A cap protects the needle, which is short and thin.
To make injection easier, the needle is surrounded by a thin layer of silicone. The barrel, which holds the insulin, is long, thin and marked with unit measurement lines. The plunger sits inside of the barrel and slides up and down, allowing you to draw the insulin in and push it out.
How to Read Measurements on Insulin Syringes
Insulin syringes come in many sizes. The following details how many units of insulin each syringe size holds:
- ¼ mL or 0.25 mL = 25 units
- 1/3 mL or 0.33 mL = 30 units
- ½ mL or 0.50 mL = 50 units
- 1 mL = 100 units
How to Choose the Right Size Insulin Syringe
Choosing an insulin syringe that is closest in size to the dosage you need is the best way to administer your medication. It is easier to read the measurements on smaller syringes, as the measuring lines are farther apart. As such, choosing the smallest syringe capable of holding the dose you need is ideal
