For surgeries that require general anesthesia, anesthesiologists often need to insert a plastic tube into a patient's trachea (wind pipe) to maintain an open airway and assist breathing. One of the tools used to do this is a laryngoscope, used to view the larynx (voice box), which is the opening to the trachea and lungs. The "blade" of the laryngoscope goes into the patient's mouth, acting as a tongue depressor and guide for the tube. In some cases, special laryngoscope blades that provide an indirect view are useful. This mirror blade was introduced in 1956 by Dr. Ephraim S. Siker (1926-2013). The example seen here was the inventor’s prototype. A copper jacket conducts heat away from the mirror, which minimizes fogging by the patient's breath. While this design helped to prevent injury in cases of difficult intubation, practice was needed in order to correctly follow the reversed image in the mirror.
