Abstract
A hemodialysis machine has ports of a disinfection manifold for receiving the arterial and venous line connectors terminating the arterial and venous lines. The ports are in fluid communication with a hydraulic system that circulates disinfection fluid through the machine including the extracorporeal circuit. The ports are constructed so as to provide a gap extending circumferentially around the arterial and venous line connectors. When the disinfection fluid circulates through the ports of the disinfection manifold, the fluid circulates around the external surfaces of the connectors as well as through the internal fluid passages, thereby insuring a complete disinfection of the connectors.
