CareFusion cares about eliminating human error and infection in hospital settings. The company sells medical equipment -- infusion and respiratory ventilation systems -- and accompanying disposables for infection prevention. Its Pyxis automated medication dispensing units cut down on clinician error when dealing with patients in critical care settings. Its Alaris infusion products include software to reduce IV medication errors. The company also makes AVEA respiratory ventilation devices, SensorMedics pulmonary care products, and V. Mueller surgical instruments. Other products and software help prevent the spread of hospital-acquired infections. Medical equipment maker Becton, Dickinson bought CareFusion in 2015.
