Excerpt

The Leech airway or “Pharyngeal Bulb Gasway”, was patented1 in 1937 by Dr. Beverley C. Leech (1898-1960). Born in Brandon, Manitoba, Dr. Leech served in World War I as a Lieutenant in the Canadian Infantry. He obtained his medical degree from McGill University in 19251 and later became the director of anesthesia at the Regina General Hospital. He is currently recognized as one of the pioneers of Canadian anesthesia.
