Abstract
A peristaltic pump includes a motor, a rotor coupled to the motor, a housing in which the rotor is arranged, and an opening and closing mechanism. The mechanism includes a tube pressuring portion, a slider, and a pivotable cover coupled to the housing and the slider and the mechanism is connected to the slider and 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. The opening and closing mechanism further includes a slider moving element attached to the slider, the pivotable cover including a rotating shaft having an extension configured to engage the slider moving element for moving the slider and also the tube pressuring portion away and towards a top of the housing in response to a respective opening and closing of the pivotable cover.
