  • Patent number: 12115295
    Abstract: A hemodialysis system including one or more ultraviolet chambers is disclosed. The hemodialysis system including a dialyzer arranged and configured to filter a patient's blood, a hemodialysis machine arranged and configured to pump, move, or the like dialysate through the dialyzer, the hemodialysis machine including an outlet valve and an outlet fluid flow path to pump or move dialysate from the hemodialysis machine to the dialyzer, and an inlet valve and an inlet fluid flow path to pump or receive dialysate from the dialyzer, and one or more ultraviolet chambers arranged and configured to kill bacteria, viruses, or a combination thereof. Thus arranged, by incorporating one or more ultraviolet chambers in strategic areas of the system, the ultraviolet chambers may eliminate, or at least greatly reduce, the possibility of cross-contamination in, for example, the dialysate, and thus eliminate the need for disinfecting the system between treatments.
