Peristaltic pumphead and methods for assembly thereof

A method of assembling a peristaltic pump, comprising:

• mounting a rotor on a molded base of the peristaltic pump, the base including a rotor receiving opening, a pair of elongated slots, and at least one cylindrical hinge portion;
• slidably mounting an occlusion bed on the base though the slots;
• inserting a first pivot pin along a first hinge axis through the at least one cylindrical hinge portion and corresponding cylindrical hinge portion of a lid, the lid including a mounting bracket extending perpendicularly relative to the first hinge axis;
• inserting a second pivot pin along a second hinge axis parallel to the first hinge axis through the mounting bracket and through a first end of each of a pair of curved arms of a linkage assembly including a cam connecting the pair of curved arms at a second end of each of the pair of curved arms opposite to the first end and having a cam surface facing the mounting bracket;
• and
• inserting a third pivot pin along a third hinge axis parallel to the first hinge axis through the cam and through a bracket of the occlusion bed,
• wherein, when the lid is in a closed position, the mounting bracket extends between the pair of curved arms to abut the cam surface and form a cooperative connection between the lid and the occlusion bed via the linkage assembly.
