Abstract:
1. A medical perfusion system comprising: a plurality of perfusion devices arranged to provide a perfusion circuit that oxygenates and circulates blood, the plurality of perfusion devices including at least a blood pump device and a level sensor device that generates a signal indicative of fluid level within a reservoir; a controller device including a touch screen input device mounted to a flat-panel display to provide information related to the perfusion circuit and to display one or more image icons indicative of one or more of the perfusion devices; a first network connection for the blood pump that provides communication between the blood pump device and the controller device; a second network connection for the level sensor that provides communication between the level sensor device and the controller device, the second network connection comprising a removable module that receives a cable extending from the level sensor device; and a communication bus that transmits configuration messages between the controller device and one or more of the perfusion devices, the communications bus interconnecting the controller device with the first network connection for the blood pump device and with the second network connection for the level sensor device, wherein the configuration messages include device association data for establishing a device association between the level sensor device and the blood pump device that persists even when there is a subsequent failure of the controller device.
