A peristaltic pump may include a rotor rotatably mounted on a base and an occlusion bed mounted on the base and moveable toward and away from the rotor. The peristaltic pump may also include a lid hingedly mounted to the base along a first hinge axis including a mounting bracket extending perpendicularly relative to the first hinge axis. A linkage assembly connecting the occlusion bed and the lid may include a pair of curved arms hingedly mounted to the mounting bracket along a second hinge axis parallel to the first hinge axis and a cam connecting the pair of curved arms and having a cam surface facing the mounting bracket, the cam being hingedly mounted to the occlusion bed at an end opposite the second hinge axis. The mounting bracket abuts the cam surface and form a cooperative connection between the lid and the occlusion bed via the linkage assembly.
