Thayer Medical

Thayer Medical is a private U.S. medical device company focused on respiratory care products rather than therapeutics. Founded in 1988 in Tucson, Arizona, the company designs, manufactures, and distributes ventilator circuit adapters, metered-dose inhaler holding chambers, and airway clearance devices for hospital, long-term care, clinic, school, pharmacy, EMS, and home-care settings. Its marketed products include LiteAire, PrimeAire, Valved Tee, MiniSpacer, and Quake, all aimed at improving aerosol drug delivery and airway clearance across the respiratory care continuum. Thayer Medical manufactures in the United States and operates under ISO 13485:2016 quality management certification, with CE-marked products and support for international distribution. The company appears to be a commercial-stage respiratory medical device manufacturer rather than a biotech or pharma developer.
