Peristaltic pump

A peristaltic pump comprising:

• a motor;
• a rotor coupled to the motor;
• a housing in which the rotor is arranged, the housing extending from a bottom to a top;
• and
• an opening and closing mechanism including a tube pressuring portion, a slider, and a pivotable cover coupled to the housing and the slider, the slider being connected to the tube pressuring portion such that a tube engaging surface of the tube pressuring portion slides towards and away from the rotor upon closing and opening of the pivotable cover, which opens and closes by pivoting around a central axis of a rotating shaft, respectively, wherein the central axis of the rotating shaft is located proximate to the bottom of the housing and the tube pressuring portion is located proximate to the top of the housing;
• wherein the housing includes a first motion link, the tube pressuring portion includes a frame that extends into the housing, the frame having at least one guiding element,
• wherein movement of the tube pressuring portion towards and away from the rotor is guided by the at least one guiding element, which interact with the first motion link, and
• wherein the tube pressuring portion includes an adjustment element configured to move the tube engaging surface of the tube pressuring portion toward and away from the rotor to adjust the peristaltic pump to various system pressures, the opening and closing mechanism further including a slider moving element attached to the slider, the rotating shaft of the pivotable cover having an extension configured to engage the slider moving element for moving the slider and also the tube pressuring portion away and towards the top of the housing in response to a respective opening and closing of the pivotable cover.
