Abstract: A method and system for collecting a double volume of red blood cells using a spinning membrane separator is provided by which a first quantity of whole blood is withdrawn from a donor; a first quantity of whole blood is flowed to the spinning membrane separator; where it is separated into a first quantity of red blood cells and a first quantity of plasma. The first quantity of red blood cells and the first quantity of plasma are then flowed to respective collection containers, and at least a portion of the first quantity of plasma is returned to the donor. A second quantity of whole blood withdrawn from the donor, and then separated into a second quantity of red blood cells and a second quantity of plasma using the spinning membrane separator. The second quantity of red blood cells and the second quantity of plasma are then flowed to the respective collection containers, and at least a portion of the second quantity of plasma is returned to the donor.

Abstract: A method and system for collecting leukoreduced red blood cells employing a spinning membrane separator including a housing having an upper end region and a lower end region in an operating position with a red blood cell outlet in the upper end region of the housing and a whole blood inlet in the lower end region of the housing. The method and system provide for flowing additive solution into the whole blood inlet of the housing to prime the separator; flowing whole blood into the whole blood inlet of the housing; separating red blood cells from the whole blood; flowing separated red blood cells out of the red blood cell outlet of the housing; combining the separated red blood cells with additive solution: passing the separated red blood cells and additive solution combination through a leukoreduction filter; and collecting the filtered red blood cells and additive solution.

Abstract: A membrane separation device is disclosed along with systems and methods employing the device in blood processing procedures. In one embodiment, a spinning membrane separator is provided in which at least two zones or regions are created in the gap between the spinning membrane and the shell, such that mixing of the fluid between the two regions is inhibited by a radial rib or ridge associated with the spinning membrane that decreases the gap between the spinning membrane and the shell to define two fluid regions, the ridge isolating the fluid in the two regions to minimize mixing between the two. Automated systems and methods are disclosed for separating a unit of previously-collected whole blood into selected blood components, such as concentrated red cells and plasma, for collecting red cells and plasma directly from a donor in a single pass, and for cell washing. Data management systems and methods and priming methods are also disclosed.
