ULTRAVIOLET DISINFECTION OF MEDICAL DEVICE ACCESS SITES

摘要

Devices and methods for automatically maintaining disinfection of access sites of medical devices using ultraviolet light are disclosed. In one example approach, a device comprises a controller and an ultraviolet light source incorporated into a chamber of an enclosure which is closeable over access ports. In response to an adjustment of the enclosure from an open position to a closed position, the controller illuminates the ultraviolet light source for a predetermined first duration while the enclosure is maintained in the closed position. Following illumination of the ultraviolet light source for the first duration, the controller illuminates the ultraviolet light source for a predetermined second duration at predetermined time intervals while the enclosure is maintained in the closed position.
