Abstract
A safety lancet device has a casing, a driver assembly and a needle hub with a needle. The driver assembly and the needle hub are mounted within the casing. The driver assembly comprises a container, a pressing unit, a controller, a pushing unit and a resilient unit. The needle hub is controlled by the driver assembly to make the needle momentarily protrude. After the needle is used, the location of the driver assembly keeps the needle from protruding. When a new needle hub replaces the used needle hub, the driver assembly will return to the original location before use and can drive the needle momentarily from the casing. Users will not forget to change the used needle. Furthermore, the safety lancet device will decrease the danger of infection.
