Abstract
A peristaltic pump comprises a tube for transporting a material, wherein the tube is arranged linearly along a longitudinal axis. The peristaltic pump further comprises a pump head for causing a squeezing of the tube, wherein the pump head is rotatable about a rotation axis.
Claims21
A peristaltic pump, comprising:
- a tube for transporting a material;
- and
- a pump head rotatable about a rotation axis and configured to cause a squeezing of a portion of the tube, the portion of the tube to be squeezed being arranged linearly along a longitudinal axis, the pump head comprising at least one squeeze member for squeezing the tube and a support member rotatable about the rotation axis,
- the support member including a slot for supporting the at least one squeeze member, the slot extending in a radial direction relative to the rotation axis throughout rotation of the support member about the rotation axis, and enabling movement of the at least one squeeze member in the radial direction.

A peristaltic pump, comprising:
- a tube for transporting a material, wherein at least a portion of the tube is arranged along a longitudinal axis;
- a pump head configured to cause a squeezing of the tube, wherein the pump head is rotatable about a rotation axis, wherein the pump head comprises at least one squeeze member for squeezing the tube, and wherein the at least one squeeze member is shiftable in a radial direction relative to the rotation axis;
- a non-rotatable guide member for guiding a movement of the at least one squeeze member;
- and
- a tube guide for guiding the tube,
- wherein the non-rotatable guide member is arranged relative to the tube guide such that a radial position of the at least one squeeze member relative to the rotation axis is confined in one radial direction by the non-rotatable guide member and in the opposite radial direction by the tube guide during a portion of the rotation of the pump head about the rotation axis, the confinement by the non-rotatable guide member and the tube guide during the portion of the rotation of the pump head about the rotation axis exerting forces on the at least one squeeze member to follow a linear path so as to enable squeezing of the tube.
