Abstract
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.
