Single-use incision lancet for taking capillary blood samples from the heels of premature and newborn babies, and infants. When the button is pressed, an extra-thin steel blade provides a fine, clean surgical cut and ensures a good flow of blood. The penetration depth is predetermined to protect against bone infections and cannot be altered. Permanently shielded blade excludes the possibility of injury or reuse. Ergonomic design enables it to be held securely and the piercing point precisely located. Sterile and individually packed in blister packaging.
