The McKesson Prevent Newborn Heel Incision Device is specifically engineered for newborns, so the stainless steel blade makes small, precise incisions in a gental, sweeping arc instead of a puncture for reduced bruising. It also features a contoured-finger design and a single direction of safety tab and trigger function for a steady and stable grip in a convenient, single-handed operation, and it has a tapered contact surface for better visibility of the site location. The extra thin, steel blade is designed to achieve the finest, cleanest surgical incision, and the consistent depth (1.0 mm) and length (2.5 mm) of incision provides excellent blood flow and a precise incision for adequate sampling; thus, reducing the need for re-sticking while the permanently retractable blade with integrated safety tab is fully shielded before and after use to minimize possible injury or reuse.
