Later Inventions
In the mid 1940s, following a suggestion of Dr. Alvin Barach, Emerson perfected the Thunberg barospirator, which caused respiration without moving the lungs at all. Emerson was involved with the development of high altitude flight valves and SCUBA gear for the Navy shortly before World War II. In 1942 he developed an automatic resuscitator. In 1949 he developed a mechanical assistor for anesthesia with the cooperation of the anesthesia department at Harvard. In 1955 he built a pleural suction pump for postoperative thoracic surgery, the Emerson Postop Pump, which is still widely used. Late in the twentieth century he assisted Alvin Barach in developing the "In-Exsufflator Cough Machine", a device to aid in secretion removal in patients with neuromuscular disease.

Famous quotes containing the word inventions:
“Opera, next to Gothic architecture, is one of the strangest inventions of Western man. It could not have been foreseen by any logical process.”
—Kenneth MacKenzie Clark, Baron of Saltwood (1903–1983)
“Our inventions are wont to be pretty toys, which distract our attention from serious things. They are but improved means to an unimproved end, an end which it was already but too easy to arrive at; as railroads lead to Boston or New York.”
—Henry David Thoreau (1817–1862)
