Claim 6:
7. An organ perfusion system comprising:
a perfusion fluid supply duct for supplying perfusion fluid to the organ;
a fluid removal duct for removing perfusion fluid from the organ;
a surrogate organ removably connected between the perfusion fluid supply duct and the perfusion fluid removal duct so as to form a fluid circuit, so that perfusion fluid can be circulated in the circuit in preparation for connection of the organ,
a sling for supporting the organ;
a sump located below the sling for collecting leaked fluid which has leaked from the organ;
a return duct connected to the sump and arranged to return leaked fluid from the sump to the fluid circuit;
an excreted fluid collection sump for collecting waste fluid produced by the organ;
an excreted fluid measurement system configured to measure, at each of a plurality of measurement times during perfusion of the organ, a respective flow rate of the fluid excreted by the organ; and
a controller having a memory and configured to store the measurement times and the respective flow rates as flow rate information in the memory; wherein the excreted fluid measurement system comprises an excreted fluid collection volume and a sensor arranged to detect when a predetermined volume of the excreted fluid has collected in the collection volume, and the controller is configured to remove the excreted fluid from the collection volume in response to said predetermined volume being reached, to determine a plurality of times between subsequent occurrences of the predetermined volume being reached, and from each of the times between subsequent occurrences of the predetermined volume being reached, to determine said respective flow rate of the excreted fluid from the organ.
