An infusion pump which is operable to pump a fluid through a tube is described. The pump comprises a shuttle having upstream and downstream sides which is operable to cyclically deform and reform the tube, a first valve associated with the upstream side of the shuttle, a second valve associated with the downstream side of the shuttle and a cam having a first face which is operable to actuate the shuttle and a second face which is operable to actuate the first and second valves.
