Insulin pens are medical devices used by people with diabetes to administer insulin. Insulin is a hormone that helps regulate blood sugar levels in the body. Insulin pens are convenient and easy-to-use devices that contain cartridges filled with insulin. Here’s how they work:
1. Loading the pen: The user inserts a new insulin cartridge into the pen. The cartridge contains a specific type of insulin prescribed by their healthcare provider.
2. Dosing: The user dials the desired dose of insulin using a dial or digital display on the pen. The dose is measured in units.
3. Injection: The pen is equipped with a disposable needle or a needle that can be replaced after each use. The user places the needle against the skin and presses a button on the pen to deliver the insulin subcutaneously (into the fatty tissue just below the skin).
Insulin pens offer several advantages over traditional vial-and-syringe injections. They provide a more convenient and discreet way to self-administer insulin. The pen’s design makes it easy to carry and use outside of the home, allowing people with diabetes to inject their insulin while on the go. Insulin pens also offer better dose accuracy and are generally more user-friendly, making them a popular choice for many individuals managing.
