This invention is directed to a method of collecting and separating whole blood into components. The method includes the steps of adding an anticoagulant having an acidic pH to a bag for collecting and/or separating whole blood, collecting whole blood in the bag, loading the bag containing anticoagulated whole blood on a rotor, spinning the bag on the rotor to separate the whole blood into at least one component; and squeezing the bag on the rotor to push the component from the separation bag into at least one satellite bag.

Adjusting pH in a method of separating whole blood

A method related to using a squeezing or transfer fluid to transfer fluid or components between bags in a centrifuge wherein the squeezing fluid can be reversed to reduce squeezing and such fluid an also be used to build up a over-pressure for rapid movement.

Method for separating a composite liquid into at least two components

Method for separating a volume of composite liquid into at least a first component and a second component including centrifuging a separation bag containing a volume of composite liquid and a volume of gas so as to sediment at least a first component and a second component separation bag; displacing a volume of hydraulic fluid against the separation bag to cause a transfer of at least one fraction of the content of the separation bag into at least one component bag connected to the separation bag; determining the volume of hydraulic fluid displaced and determining the volume of the composite liquid or the transferred components from the determined volume of displaced hydraulic fluid.

Method of separating a composite liquid into at least two components

A method used in connection with processing of blood components, wherein blood products are then filtered via a filter rotating along with a centrifuge rotor and 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.

Blood component processing system method

A method for separating a volume of a composite liquid into at least a first component and a second component is performed in a centrifuge cooperating with a separation bag containing the volume of composite liquid. The separation bag is connected to at least a first component bag and a second component bag. The separation bag is spun so as to centrifuge the volume of composite liquid and cause the sedimentation of the at least first and second components. When the at least first and second components have sedimented, the first component is transferred at least one first transfer flow rate into the first component bag. When the first component has been transferred into the first component bag, the second component is transferred into the intermediate component bag at least one second transfer flow rate that is different from the at least one first transfer flow rate.

Method for separating a volume of composite liquid into at least two components

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.

The separation bag is connected to at least a first component bag and a second component bag. The separation bag is spun so as to centrifuge the volume of composite liquid and cause the sedimentation of the at least first and second components.

Apparatus and method for separating a volume of composite liquid into at least two components

A centrifuge for processing blood and blood components in a processing bag connected to at least one secondary bag comprises a rotor for spinning a processing bag and separating a content thereof in at least two components, and a squeezing member for exposing a processing bag to an external pressure and causing a transfer of a separated component from a processing bag into a secondary bag. Electrically powered devices, such as valves and photocells, are mounted on the rotor for controlling a transfer of fluid from a processing bag into a secondary bag. An electrical power supply system supplies the electrically powered devices with electrical power through the rotor.

Centrifuge for processing a blood product with a bag set having a processing bag

The claimed invention refers to a centrifuge intended for processing blood and blood components and with its function based on the effective utilisation 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 () inner periphery, shows at least three supports () 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 () which includes a clamp function () that clamps ring bag () securely along and between supports (). Furthermore, in the invention these supports () have, on the one hand, built-in valve functions for communication between the ring bag and the respective secondary bags can be actively controlled and, on the other hand, sterile welding functions for communication between ring bag () and the respective secondary bags when interruption and blocking is required.

Method for processing a blood product with a bag set having a multi-way connector

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. The device includes a centrifuge machine containing one or more suspended product bags that can be oscillated forwards and backwards in an incomplete pendulum swing by operation of a motor mounted in a lid of the machine. The product bag(s) are connected to a ring bag for subsequent processing and to a bag containing diluting solution by a multi-way connector.
