Hans Rudolph

Hans Rudolph is a private U.S. respiratory medical device company that designs and manufactures valves, masks, pneumotachometers, calibration syringes, lung simulators, connectors, and related instrumentation for respiratory care, pulmonary function testing, sleep medicine, research, and OEM customers. The company traces its roots to the 1930s and was incorporated in 1960, with the business still operating as an active family-run manufacturer in Kansas. Its product portfolio includes CPAP/BiLevel/NIV oro-nasal masks, breathing valves, flow measurement systems, data acquisition systems such as SmartLab, and accessories used in hospitals, clinics, laboratories, and home-care settings. Hans Rudolph appears to be a niche commercial-stage healthcare manufacturer rather than a drug-development biotech company, with revenues generated from marketed respiratory products sold directly and through distributors worldwide.
