An insulin syringe consists of three main parts, each designed for safe and accurate insulin delivery.
Insulin Syringe Components
The three components of an insulin syringe, as highlighted in the reference, are:
- Needle: The needle is short and thin, coated with silicone for easier insertion and reduced discomfort. It's protected by a cap until use.
- Barrel: This is the long, hollow chamber that holds the insulin. It's marked with measurements to allow for precise dosing.
- Plunger: The plunger is used to draw insulin into the barrel and expel it during injection.
| Component | Description | Function |
|---|---|---|
| Needle | Short, thin, silicone-coated; covered with a protective cap. | Penetrates the skin to deliver insulin; silicone coating reduces pain. |
| Barrel | Long, thin, hollow chamber. Marked with units of insulin. | Holds the insulin and allows for accurate measurement of the dose. |
| Plunger | A rod that fits inside the barrel. | Used to draw insulin into the syringe and to push the insulin out during injection. |
Understanding these components helps in the proper use and handling of insulin syringes, ensuring accurate and safe insulin administration.
