Insulin pen
A medical device used to inject insulin for the treatment of diabetes, designed to be more convenient and easier to use than traditional vial and syringe methods. Insulin pens typically consist of a pen-like device that holds an insulin cartridge and a disposable needle, with a dial to set the dose and a button to inject the insulin, offering more precise dosing and discreet usage. They are particularly beneficial for individuals with diabetes who require multiple daily insulin injections.
