Provided is a fluid circuit comprising a first container configured to receive a transplant component and a second container configured to receive an apoptotic component. Provided is a separator configured to associate with the fluid circuit and separate whole blood into a red blood cell component, a plasma component, and a white blood cell component. Whole blood is directed into the fluid circuit and the separator. The whole blood is separated into the red blood cell component, the plasma component, and the white blood cell component. A first portion comprising the transplant component of the white blood cell component is directed to the first container. A second portion of the white blood cell component is directed to the second container and the second portion is rendered apoptotic.

DIALYSIS MACHINE
The present invention relates to a blood treatment device, preferably a dialysis machine, that is configured to be used with a disposable, preferably with a cassette system, and that has a coupling region for the disposable and a control unit that is configured to carry out a plurality of pressure measurements at different times during a coupling procedure of the disposable to the blood treatment device, with a quality of the coupling of the disposable to the blood treatment device being able to be determined with reference thereto. The present invention further relates to a method of monitoring a coupling procedure of a disposable to a blood treatment device.
Compact reverse flow centrifuge system
Provided is a chamber configuration for a reverse flow centrifuge, and a reverse flow centrifuge system configured for low fluid volume and small radius rotation. The compact reverse flow centrifuge system has a reusable subsystem and a single use replaceable subsystem. The replaceable subsystem comprises a separation chamber, fluid delivery manifold and rotational mounting connecting the separation chamber to the fluid manifold. The single use replaceable subsystem provides a closed environment for execution of reverse flow centrifugation processes. The separation chamber has a substantially conical fluid enclosure portion connected to a neck portion, and a dip tube extends centrally through the conical fluid enclosure to provide a fluid path to the tip of the conical fluid enclosure.
Method for providing operation data to a fluid processing medical apparatus using a medical accessory
A method for providing operation data to a fluid processing medical apparatus and a medical accessory have been provided. The method comprises the steps of providing the medical apparatus (10) with a readable element (12); acquiring configuration data associated to the readable element (12) of the medical apparatus (10) by relatively approaching a data acquisition unit (22) of a medical accessory (20) and the readable element (12) of the medical apparatus (10); establishing a wireless communication between medical accessory (20) and the medical apparatus (10) based on the configuration data; providing a medical component (40) having a readable element (42); acquiring operation data associated to the readable element (42) of the medical component (40) by relatively approaching the data acquisition unit (22) of the medical accessory (20) and the readable element (42) of the medical component (40), the medical component (40) being destined to be operatively coupled to the medical apparatus (10); and providing the operation data to the medical apparatus (10) using the wireless communication.
Method for operating an extracorporeal blood treatment apparatus and blood treatment apparatus
The present invention relates to a method for operating an extracorporeal blood treatment apparatus having an extracorporeal blood circuit for a hemodialysis and/or hemofiltration and/or hernodiafiltration by controlling an impeller pump. The invention furthermore comprises that the impeller blood pump is operated in a pulsating manner by adding a pulsating speed portion to a first constant speed.
Systems and methods for treating a biological fluid with light in the event of a bulb outage
Methods and systems for treating a biological fluid with light are disclosed. The methods and systems include determining the light dose being delivered to a biological fluid and adjusting the duration of a treatment or the intensity of light emitted in the event of a detected light source outage.
Systems and methods for platelet filtration using an additive
Systems and methods are provided for collecting a platelet product from a fluid including platelets and plasma. Platelet-rich plasma is separated from at least a portion of another constituent of the fluid and then may be further separated into concentrated platelets and platelet-poor plasma, with the concentrated platelets being resuspended. Separated platelets are conveyed through a size exclusion filter and into a platelet storage container. The size exclusion filter is configured to remove platelet clumps and/or particles larger than a platelet from the separated platelets. Subsequently, an additive is conveyed through the size exclusion filter and into the platelet storage container. Conveying additive through the size exclusion filter improves platelet recovery in the platelet product by displacement of separated platelets with the additive and may also break up any platelet clumps that are present in the size exclusion filter.
Combination kidney and liver dialysis system and method
A combination kidney and liver dialysis system and method provides a portable, lightweight hemodialysis device that removes uremic toxins, hepatic toxins, water, and impurities from the blood. The method comprises separating the blood into a plasma portion and a cellular portion, immediately returning the cellular portion to the body, providing large volumes of replacement fluids, diluting the plasma portion with replacement fluids, and then manipulating the plasma portion of the blood to pass through hemoperfusion membranes, hemodiafiltration membranes, and extracorporeal membrane oxygenation membranes. Dialysis is performed on the plasma portion of the blood with an albumin dialyzer against an albumin dialysate and a high molecular weight cut off membrane. Dialysis is performed on the plasma portion of blood with a lipid dialysate comprising 10-30% lipid composition, and a high flux dialyzer. The system can also use any form of dialysis technology including hollow fiber, flat plate and microfluidic technology.
