Client: Homunculus, Inc.


The Stethoscope Reflex Hammer is a simple device that snaps around the chest piece of a stethoscope to create a reflex hammer. The intended users are doctors performing general exam on patients. Previously, doctors would have to carry both a stethoscope and a reflex hammer with them at all times. The reflex hammer needs weight and is, therefore, heavy and bulky to carry–typically sticking awkwardly out of lab coat pockets. The challenge was to design a reflex hammer attachment that would not interfere with the stethoscope’s vital function and would fit various stethoscope models.
