摘要:
A centrifugal fluid separation system is disclosed for centrifugally separating a composite fluid into components thereof. This centrifugal separation system includes at least a centrifugal rotor which has a composite fluid containment area, a fluid flow channel/tubing and at least one separated component collection area defined therein. A composite fluid to be separated is delivered to the fluid containment area where under centrifugal forces the composite fluid is separated into components and then from which a component travels through an outlet channel to a respective separated component fluids flowing therethrough. A centrally disposed pump is also provided to move the separated component(s) to the collection area(s). Optical sensing of the interface of the separated fluid components may be used with a clamp to stop flow. A disposable bag and tubing system is also disclosed for use with reusable rotor devices.

An apparatus and method are disclosed for filtering or separating particles. The apparatus has a centrifuge rotor rotatable about an axis of rotation. A fluid chamber rotates with the rotor. A substance is supplied to the inlet of the chamber. A saturated fluidized bed of first particles forms within the fluid chamber and obstructs flow of second particles through the chamber. Additive substances alter sedimentation velocity of the first particles to modify the filtration characteristics of the saturated fluidized bed.

A system and method are used in connection with processing of blood components. The processing of blood components may involve centrifugal separation and/or filtering of the blood components. In some examples, at least some blood components are centrifugally separated in a chamber and then filtered via a filter rotating along with a centrifuge rotor, wherein the filter is located closer than the chamber to an axis of rotation of the rotor. The filter may include a porous filtration medium configured to filter leukocytes, platelets, and/or red blood cells. Some examples include a pressure sensor sensing pressure of pumped blood components. The sensed pressure may be used in connection with controlling the pumping of the blood products and/or in connection with determining the location of an interface associated with the blood products. Other uses of the sensed pressure are also possible.
摘要:
A method is disclosed for collecting and processing whole blood. Whole blood is collected at several remote donor sites and transported to a central blood-processing center, where information regarding demand for blood products is used to direct processing of whole blood into blood products. Whole blood is initially collected in collection bags unattached to satellite bags instead of commonly used multiple bag sets. When the determination is made at the blood processing center as to which blood products are to be made, the appropriate satellite bags and/or other system components are sterile docked to the blood-collection bag and the whole blood is processed. The use of blood-collection bags initially unattached to satellite bags eliminates waste and simplifies the transportation and processing of whole blood. Also disclosed are blood collection systems that remove leukocytes and collect whole blood into blood-collection bags unattached to satellite bags.
