Abstract
Blood processing systems, devices, and methods including a durable hardware component, a disposable fluid flow circuit, and a controller configured to determine an optimum flow rate. More particularly, blood processing systems and devices including a controller configured to determine an optimum flow rate for return fluid and to determine false positive empty container detections.
Claims26
A blood processing system comprising:
- a reusable separation device, wherein the separation device includes a separator and a weight scale;
- a disposable fluid circuit including a separation chamber and a fluid container, wherein the disposable fluid circuit is configured to be associated with the reusable separation device and the fluid container is configured to be associated with the weight scale;
- and
- wherein the reusable separation device includes a controller configured to execute a blood processing procedure and to determine an optimum flow rate for pumping a fluid from the fluid container.
