  • Publication number: 20040026341
    Abstract: 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.

  • Patent number: 6656105
    Abstract: A centrifuge intended for processing blood and blood components of use with a ring type blood processing bag with associated secondary bags. The rotor of the centrifuge has supports arranged along its periphery and a rotating inner lid a clamp function that secures the ring bag along and between supports. The supports can also function as valves or a welding apparatus for the tubing between the processing bag and the associated secondary bags.

  • Publication number: 20020119880
    Abstract: The claimed invention relates to a method and a device for processing blood concentrate products before they are exposed to a continued process for extracting those remaining medicinally interesting sub-components. The appropriate pre-processing, in relation to the invention, primarily entails a mechanically powered resolution of the viscous flowing concentrate products in a diluting solution for the adaptation of the total products for a renewed centrifuging.

  • Publication number: 20020086788
    Abstract: The claimed invention refers to a centrifuge intended for processing blood and blood components and with its function based on theeffective utilization of ring type blood processing bags with associated secondary bags and other accessories. The most outstanding feature of the centrifuge, in accordance with the claimed invention, is that its rotor, at the same intended height of the ring bag (22) inner periphery, shows at least three supports (9-11) arranged along this periphery and intended to locate the ring bag's inner strengthened periphery edge on guide holes at the same time as the centrifuge and its rotor is equipped with a joint rotating inner lid (6) which includes a clamp function (7) that clamps ring bag (22) securely along and between supports (9-11).
