lansetter

A lansetter is a type of medical device used for obtaining small blood samples. It is commonly employed for diagnostic purposes in various healthcare settings. The device typically consists of a small lancet, which is a sharp needle or blade, housed within a mechanism designed to penetrate the skin quickly and with minimal discomfort.

Lansetters are designed for single use to maintain sterility and prevent the transmission of infections. After the lancet pierces the skin, a small drop of blood is collected, often onto a test strip or directly into a capillary tube. This blood sample is then used for a variety of tests, such as glucose monitoring for individuals with diabetes, hemoglobin testing, or other rapid diagnostic assays.

The development of lansetters has aimed to improve patient comfort and ease of use for healthcare professionals and individuals performing self-testing. Various designs exist, including manual push-button devices and automated models that retract the lancet immediately after use. Safety features are often incorporated to prevent accidental needle sticks. The widespread availability and affordability of lansetters have made them a staple in both clinical environments and home healthcare.
