A laryngoscope is an instrument used to view the larynx (voice box), which is the opening to the trachea and lungs. It consists of a “blade,” which goes into the patient’s mouth, and a handle. Prior to 1943 when Macintosh introduced his curved blade, most laryngoscope blades were long and straight. The straight blades were used to directly hold the epiglottis. Macintosh’s curved blade works differently: it indirectly opens the epiglottis by applying pressure to a space between the root of the tongue and epiglottis, called the vallecula. The flange running along the left lower edge of Macintosh’s blade was also a novel innovation. It was designed to move the tongue to the side, which improved the view of the larynx and made more room for a breathing tube. The Macintosh Laryngoscope remains one of the most popular blades worldwide. (Source: Wood Library Museum) This laryngoscope was previously owned by John Mainland, as evidenced by the name etched into the handle. Mainland graduated from the University of Melbourne in 1950 with a Bachelor of Science degree. After researching and completing his medical degree, Mainland entered into the field of anaesthetics, training at the Royal Women's and Royal Children's Hospitals, later Alfred Hospital, in 1959. He completed training in 1964 and remained at the Alfred Hospital. During his career, he also became the first anaesthetist appointed to the position of Professor in Victoria. His other achievements include manufacturing a respiratory monitoring module that accompanied astronauts on the United States moon landing and developing a stimulator to lessen the risk of deep vein thrombosis in surgical patients. Mainland became a Fellow of the Australian and New Zealand College of Anaesthetists in 1992, retiring from the profession in 1997.Oblong shaped handle with textured grip.
