An injection port works by providing a consistent and convenient access point for medication delivery under the skin, eliminating the need for multiple needle sticks.
Understanding Injection Ports
An injection port, also known as an infusion port or subcutaneous port, is a small device designed to make administering subcutaneous injections easier and less painful. Instead of injecting medication directly through the skin each time, you inject it through the port. Here's a breakdown of how it works:
Components and Application
- Insertion: Injection ports typically come with a built-in inserter to facilitate easy application.
- Cannula Placement: When applied, a short, soft, flexible tube called a cannula is inserted and remains under the skin.
- Securing the Port: The port is secured to the skin with an adhesive.
- Medication Delivery: Once the port is in place, medication is injected through the port and into the cannula, which delivers it under the skin. Importantly, the device itself does not store any medication.
Advantages of Using an Injection Port
- Reduced Pain: Lessens the pain associated with frequent injections, as only one insertion is needed every few days.
- Convenience: Simplifies the injection process, making it easier to administer medication.
- Reduced Skin Trauma: Minimizes skin irritation and damage from repeated needle sticks.
Usage Example
Imagine you need to inject a medication daily. Instead of piercing your skin with a needle every day:
- You insert the injection port.
- For the next few days (depending on the port's lifespan), you simply inject your medication through the port.
- When the port's lifespan is over, you remove it and insert a new one at a different site.
