Patent ID: 8905730

Claim:
A peristaltic pump comprising: a tube provided with a transponder having a data storage memory and means for transmitting tube data stored in the data storage memory; and a pump unit in which the tube is mounted, the pump unit having drive means for deforming the tube to perform a peristaltic action, and a reader for reading tube data transmitted from the transponder; wherein the reader comprises: tube data memory adapted to store the tube data transmitted from the transponder; a control data memory adapted to store control data relating to the tube; a comparator adapted to compare the tube data stored in the tube data memory and the control data stored in the control data memory; wherein the control data includes data representing the predicted operational life of the tube based on the average operational life for other tubes previously operated for their full operational life in the same environment, and wherein, when the tube fails, the comparator compares the operational life of the tube with the predicted operational life and updates the predicted operational life stored in the control data memory to include the operational life of the tube.
