Embodiment Construction

[0025] The present invention will be described with reference to the accompanying drawings. In general, the main aspects of the invention relate to procedural and structural improvements in blood processing separation systems, or improvements to subassemblies for use with blood processing separation systems. However, some of these improvements may be applicable to other extracorporeal blood processing applications regardless of whether any blood components are returned directly to the donor or otherwise; and these are within the scope of the present invention.

[0026] figure 1 A preferred blood separation system 2 for use in and / or with the present invention is schematically illustrated in . The system 2 is preferably configured for a continuous blood fractionation process. Typically, whole blood is drawn from a donor and is supplied substantially continuously to a blood component separation device 6 where the blood is continuously separated into various component types and...

Abstract

A centrifugal blood processing device comprising: a centrifuge rotor, a separation chamber, and a tube set for conducting blood components and fluids; a method for controlling the blood processing device comprising: separating blood in the separation chamber components, flowing the blood components out of the separation chamber and into a concentration chamber, concentrating the blood components in the concentration chamber, and flushing the blood components from the concentration chamber . The method also includes simultaneously flowing a solution, such as a wash solution or PAS, into the concentration chamber between the separation chamber and the concentration chamber.

Description

technical field [0001] The present invention relates generally to the field of methods and apparatus for extracorporeal blood treatment, which methods and apparatus are particularly useful in the collection of blood components, and more particularly to the field of Method and apparatus for centrifugation of platelets from other blood components with reduced plasma content. Background technique [0002] One well-known form of extracorporeal blood processing involves a separation (aphaeresis) system and process in which blood is removed from a donor or patient (hereafter collectively referred to as the donor) and directed to a blood component separation device such as a centrifuge ), and separated into various blood component types (eg, red blood cells, white blood cells, platelets, plasma) for collection or treatment purposes. One or more or all of these blood component types may be collected and processed prior to storage for therapeutic purposes or returned to the patient,...
