Appl. No.:

09/615390

Inventors:

Robert J Cantu - Lake in the Hills IL
Russel Stinoff - Alrlington Heights IL

Assignee:

Baxter International Inc. - Deerfield IL

International Classification:

G06F 1700

US Classification:

702 50, 702173, 702 55, 210782

Abstract:

Fluid processing systems and methods make use of a replenishable source containing a volume of a processing fluid that is dispensed during a processing period. A processor serves to sequentially pause and resume the processing period. The processor records weight values of the source at commencement of the processing period; upon pauses in the processing period; and upon resumptions of the processing period. At termination of the processing period, the processor generates a total volume value of processing fluid dispensed from the source during the processing period, which takes into account replenishment of the processing fluid when the processing period is paused. The systems and methods can be integrated into blood processing circuits to monitor the introduction of anticoagulant.

International Classification:

US Classification:

Abstract:

Blood processing systems and methods rotate a processing chamber on a rotating element. The processing chamber includes a first compartment and a second compartment. Blood is conveyed into the first compartment for centrifugal separation into components. A liquid free of blood occupies the second compartment to counter-balance the first compartment during rotation on the rotating element. In one embodiment, the second compartment is served by a single fluid flow access. Prior to use, the single access is coupled to tubing, through which a vacuum is drawn to remove air from the second compartment. While the vacuum exists, communication is opened between the tubing and a source of liquid. The vacuum draws the liquid into the second compartment through the single access, thereby priming the second compartment for use.

International Classification:

A61M 1/14

US Classification:

604 401, 210646

Abstract:

Systems and methods for controlling fluid flow during a fluid exchange procedure. In one aspect, a system is provided for controlling a net fluid volume difference of a patient during and/or after a fluid exchange procedure. The system comprises a first flow path for flowing at least a first fluid from the patient and a second flow path for flowing at least a second fluid to the patient. First and second reservoirs are respectively associated with the first and second flow paths. A controller is associated with the first and second flow paths for controlling first and second flow rates and operable to determine an actual flow rate for each first and second fluid and to change a first or second flow rate in response to a difference between at least one of such flow rates and its respective actual flow rate.

International Classification:

US Classification:

222 58, 222 61, 222 1

Abstract:

Systems and methods for determining when a fluid supply container of a blood processing apparatus becomes empty. The system uses a scale to monitor and detect when a fluid supply container is empty based on the rate of change of the container weight, and a controller receives a signal from the scale and controls the operation of a pump to stop pumping when the fluid supply container is empty.

International Classification:

B01D 2126

US Classification:

210745

Abstract:

Blood separation systems and methods employ a rotating chamber. The chamber includes an inlet region where whole blood enters for centrifugal separation into packed red blood cells, a plasma constituent, and an interface carrying mononuclear cells between the packed red blood cells and the plasma constituent. The packed red blood cells in the chamber have a hematocrit value H. sub. PRBC. A controller operates in a first mode to convey whole blood into the inlet region while removing packed red blood cells and the plasma constituent from the chamber and while maintaining the interface within the chamber. The controller also operates in the first mode to maintain a set H. sub. PRBC by conveying packed red blood cells into the inlet region.
