A pivotable cover secures a pump header or tubing to a peristaltic pump of a dialysis machine. The cover includes an integral raceway for engaging the pump header as a rotor of the peristaltic pump rotates along the integral raceway. The cover is pivoted away from the dialysis machine to separate the raceway from the rotor and provide substantial access for loading the pump header about the rotor. The cover is then closed to secure the pump header in place and properly position the integral raceway in relation to the pump rotor. If the pump header is connected to a blood tubing set, the cover also secures the blood tubing set in position against the dialysis machine. A detachable hinge connects the cover to the dialysis machine to allow the cover to be completely detached from the dialysis machine. The detachable cover provides complete access for cleaning the area surrounding the peristaltic pump rotor and the location where the blood tubing set is located.

[ What is claimed is:] [1.] In a dialysis machine having a hydraulic flow path for delivering dialysate to a dialyzer, peristaltic blood pump with a rotor for controlling a flow of blood through an extracorporeal flow path which includes the dialyzer, the extracorporeal flow path including a flexible pump header which the rotor pinches during rotation to pump blood in the extracorporeal flow path, and an improved cover for securing the pump header relative to the rotor for blood pumping, said cover comprising:a hinge pivotably connecting one end of the cover to the dialysis machine to allow the cover to pivot between a closed position wherein the pump header is pinched by the rotor for blood pumping and an open position extended away from the dialysis machine wherein the pump header is not pinched for blood pumping; andan integral raceway of the cover for engaging the flexible pump header to allow the rotor to pinch the pump header against the raceway during blood pumping, said raceway engaging the flexible pump header for blood pumping only when the cover is pivoted to the closed position; and wherein:said hinge allows selective detachment of the cover from the dialysis machine.
