Twist Lancet

A twist lancet is another type of medical tool used for blood sampling in patients. It works on the same principle as a safety lancet, but instead of being pressure-activated, it requires a twisting motion to activate it. The twist lancet device is also comprised of a small needle surrounded by a protective shield. To use the device, the user twists the top of the lancet to expose the needle, then places it against the skin, and twists it again to activate the needle and obtain the blood sample. Like the safety lancet, the twist lancet is designed for a single use and is then discarded. The twist lancet is often preferred by patients who find the pressure-activated lancets to be uncomfortable or difficult to use.
