Lancing Device (Pen)

Lancing Device (Pen)

A lancing device is a small handheld device used to prick the skin and draw a small amount of blood for testing. Lancing devices come in different shapes and sizes, but they all have the same basic components: a lancet, a trigger mechanism, and a depth-adjustment feature. The device also contains a spring-loaded mechanism that pierces the skin with a tiny needle, usually called a lancet. The needle is typically very thin, about the size of human hair, and causes minimal pain or discomfort. People with diabetes use lancing devices that need to monitor their blood glucose levels regularly.
