Abstract
Disclosed herein is a peristaltic pump for medical applications comprising a motor, a rotor coupled to the motor, a housing in which the rotor is arranged and an opening and closing mechanism comprising a tube pressuring portion, a slider and a pivotable cover coupled to the housing and the slider. The opening and closing mechanism is accentuated by the pivotable cover, which pivotable cover is connected to the tube pressuring portion via elastic elements. The elastic elements are thereby connected via at least one adjustable element so that the tension or pretension in the elastic element can be adjusted to tube types and material, to the viscosity of the pumped fluid and to the amount of fluid that needs to be pumped.
Claims17
A peristaltic pump comprising:
- a motor;
- a rotor coupled to the motor;
- a housing in which the rotor is arranged;
- 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 opening and closing mechanism further including an elastic element 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, respectively,
- wherein the housing includes a first adjustable motion link, the tube pressuring portion includes a frame that extends into the housing, the frame having at least two guiding elements,
- wherein the tube pressuring portion's movement towards and away from the rotor is guided by the at least two guiding elements, which interact with the first adjustable motion link, and
- wherein the tube pressuring portion includes an adjustment element to which the elastic element is connected such that a tension in the elastic element is adjustable, the opening and closing mechanism further including a post attached to the slider, the pivotable cover including a rotating shaft having an extension extending perpendicular to a longitudinal direction defined by the rotating shaft, the extension configured to engage the post for moving the slider and, via the elastic element, 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.
