Injector Pen

An Injector Pen (pronounced: in-jek-tor pen) is a medical device used for the subcutaneous delivery of medications, most commonly insulin for people with diabetes.

Etymology

The term "Injector Pen" is derived from its function. The word "injector" comes from the Latin injicere meaning 'to throw in', and "pen" is used due to the device's resemblance to a writing pen.

Function

The Injector Pen is designed to deliver a precise dose of medication under the skin (subcutaneously). It is commonly used by individuals with diabetes to administer insulin, but can also be used for other medications such as glucagon or growth hormone. The pen contains a cartridge of medication, a dial to set the dose, and a disposable needle.

Usage

To use an Injector Pen, the user first dials the required dose of medication. The pen is then held against the skin and the button is pressed to deliver the medication. The needle is then removed and disposed of safely.

Advantages

Injector Pens offer several advantages over traditional syringes. They are more convenient and portable, making it easier for individuals to manage their medication while on the go. The dose can be easily adjusted, reducing the risk of errors. They are also less intimidating than syringes, which can make them a better option for children or individuals with a fear of needles.
