Ultrasonic wave nebulizers were invented in 1965 [16] as a new type of portable nebulizer. The technology inside an ultrasonic wave nebulizer is to have an electronic oscillator generate a high frequency ultrasonic wave, which causes the mechanical vibration of a piezoelectric element.
Peter Tsai (蔡秉燚; born February 6, 1952) is a Taiwanese-American inventor and material scientist who is best known for inventing and patenting improved meltblown filtration manufacturing techniques, used in respirators (like N95 respirators, which is a 1995 NIOSH standard made to address the shortcomings of USBM standards).
While the 4 other competing type of inhalers are relatively new inventions. The first "gas inhaler" (or breathing apparatus) was invented and designed by James Watt in 1793. The first nebulizer was invented and designed by Sales-Girons in 1858. The first dry powder inhaler was invented by Newton in 1864.
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
The Both respirator, a cheaper and lighter alternative to the Drinker model, was invented in Australia in 1937. British philanthropist William Morris financed the production of the Both–Nuffield respirators, donating them to hospitals throughout Britain and the British Empire. During the polio outbreaks of the 1940s and 1950s, iron lungs ...
USPTO trading card featuring Bird. Forrest Morton Bird (June 9, 1921 – August 2, 2015) was an American aviator, inventor, and biomedical engineer.He is best known for having created some of the first reliable mass-produced mechanical ventilators for acute and chronic cardiopulmonary care.
At the tip of the nebulizer, the liquid is pulled into the gas stream by surface tension along a spout dipping into the gas stream. This allows the gas to impact the liquid, and has the liquid interact in the center of the gas flow where the gas flow speed is highest, producing a better transfer of energy from the gas to the liquid, and ...
Frederick McKinley Jones (May 17, 1893 – February 21, 1961) was an American inventor, entrepreneur, engineer, winner of the National Medal of Technology, and an inductee of the National Inventors Hall of Fame. [1] Jones innovated mobile refrigeration technology.
