Puritan Bennett has been a provider of respiratory products since 1913 originally as a medical gas supplier. In addition to critical care ventilation, Puritan Bennett provided medical devices for patients outside of the acute care environment. Its products included portable ventilation, oxygen therapy systems, sleep diagnostic and sleep therapy equipment, spirometry and other respiratory care products.


In 1913, Puritan Bennett entered the medical gas industry.[1][2] In 1940, founder Ray Bennett invented a mechanical ventilator as an alternative to the iron lung machine.[3]

In 1995, Nellcor acquired Puritan Bennett and the newly expanded company was renamed Nellcor Puritan Bennett.[4] In 1997, Nellcor Puritan Bennett became a part of Mallinckrodt, a medical products company with product lines in respiratory care, diagnostic imaging and analgesic pharmaceuticals. In 1998, Puritan-Bennett Aero Systems (PBASCO[2]) was sold to BE Aerospace Inc.[5][6]

In 2000, Tyco International acquired Mallinckrodt to become a Tyco Healthcare company.[7][8] In 2007, Covidien spun off from Tyco International[9] and inherited Puritan Bennett along with other Tyco Healthcare Brands.[10]

In 2015, Medtronic acquired Covidien and inherited all brands, including Puritan Bennett.[11]
