An infusion pumping mechanism includes a motor, a plurality of pump fingers and an opposing plate. Each finger of the pump fingers includes a body portion and a head portion. The head portion includes a tip that is configured to contact and occlude a tube installed in the pumping mechanism. The opposing plate includes an anvil with a plurality of force concentrators. A force concentrator of the plurality of force concentrators corresponds to a respective pump finger of the plurality of pump fingers. Additionally, the force concentrator includes a concentration surface configured to contact and occlude the tube. The force concentrator is aligned with a tip of the respective pump finger such that as the finger is directed towards the tube and contacts the tube, both the tip and the force concentrator provide pressure to opposite sides of the tube and at least partially occlude the tube.

Infusion pump alignment features for vertically-oriented IV tubes are disclosed. In an example, an infusion pump housing includes a tube channel having a radial curvature for bending an IV tube from a horizontal orientation to a vertical orientation when the infusion pump is positioned for operation. The housing also includes a hood having a first side and a second side that are divided by the tube channel. The infusion pump has a door that is connected to the housing for enclosing the tube channel and the hood. The door includes a cavity having dimensions to receive the hood when the door is in a closed position. The hood is configured to engage the cavity to prevent the door from closing if the IV tube is not positioned along the tube channel.

An infusion pump for delivering an intravenous ('IV') fluid includes a housing comprising an actuation area that engages a portion of an IV tube. The actuation area includes a first end that receives the IV tube from a fluid container and a second end that provides the IV tube to a patient. The housing also includes a seal section located along a perimeter of at least a portion of the actuation area. The seal section includes a gasket rib positioned along the seal section and a tube channel configured to cradle the IV tube. The example infusion pump also includes a door connected to the housing and configured to engage the gasket rib to enclose the actuation area of the housing.
