Abstract
An infusion pump includes upstream and downstream valves, a pressing surface disposed between the valves which presses on an infusion tube, a pressure sensor which measures pressure within the infusion tube, and a controller. In response to the pressure, the controller determines that there is an occlusion in the infusion tube downstream of the downstream valve, and in response thereto, toggles the upstream valve and the downstream valve. The toggling includes sequentially, (a) while the upstream valve remains closed, isolating a segment of the infusion tube between the valves by closing the downstream valve, (b) while the downstream valve remains closed, reducing pressure in the isolated segment by opening the upstream valve, (c) while the downstream valve remains closed, closing the upstream valve, and (d) while the upstream valve remains closed, reducing pressure downstream of the downstream valve by opening the downstream valve. Other applications are also described.
