Welch Allyn Miller Laryngoscope Blades All of Welch Allyn's MacIntosh, English MacIntosh, and Miller standard laryngoscope blades are constructed with a single piece of stainless steel. This one-piece design is more robust than the typical competitive product. And it's safer as well. The removable light pipe virtually eliminates the chance for cross-contamination, and allows low-cost upgrade to fiber optic technology.
