Two-sided chest piece with tunable diaphragms on both the adult and pediatric sides
Single-piece tunable diaphragm is easy to glue, and easier to scrub because its surface is smooth without crevices
Pediatric side converts to a traditional open bell by replacing the only-piece diaphragm with a non-chill rim
Next-generation tubing provides longer life because of improved resistance to skin oils and alcohol; less most probably to select up stains
Reusable LED penlight with sealed concentric beam to light up the eyes, ears, and throat
Dual-serve as pocket clip for portability and for activating the sunshine
Pupil gauge imprinted on the body of the penlight for determining pupil size
