1. A peristaltic pump, comprising:
a tube for transporting a material, wherein 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 each of the at least one squeeze member includes a shaft extending parallel to the rotation axis; and a guide member for guiding a movement of the at least one squeeze member, wherein a perimeter of the guide member comprises a curved section and a linear section extending parallel to the longitudinal axis, wherein the peristaltic pump is configured such that the at least one squeeze member is shiftable in a radial direction relative to the rotation axis, and wherein the shaft of the at least one squeeze member directly contacts the perimeter of the guide member such that the guide member confines movement of the at least one squeeze member in the radial direction towards the rotation axis.
