1. An infusion pump for delivering an intravenous (“IV”) fluid comprising:
a housing having a vertical orientation when the infusion pump is positioned for operation, the housing having a top side configured to engage a horizontal portion of an IV tube; and
a seal section located along at least the top side of the housing, the seal section including
at least one rib positioned along the top side of the housing, the at least one rib extending vertically from the top side and defining a tube window having a width to enable the horizontal portion of the IV tube to pass between edges of the tube window, and
a tube channel aligned with the tube window, the tube channel having a horizontal orientation when the infusion pump is positioned for operation, the tube channel being in connection with the tube window and configured to contact a bottom side of the horizontal portion of the IV tube,
wherein the at least one rib and the tube channel both include an elastomeric material to enable the at least one rib to create a seal against a door connected to the housing and enable the tube channel to contact the bottom side of the horizontal portion of the IV tube without causing compression or fluid occlusion of the IV tube.
