Abstract
A blood component collection system is disclosed with optimization capabilities. In one embodiment, process parameters are derived from an input/configured predetermined blood component yield and which is based upon the maximization of at least one process parameters. Thereafter, the blood component collection procedure is performed with these derived process control parameters. In another embodiment, process parameters are derived from an input total procedure time from a maximized value for at least one of the other process control parameters so as to maximize blood component yield in this fixed time. Thereafter, the blood component collection procedure is performed with these derived parameters.
Claims15
A method for collecting at least one predetermined type of blood component from a source of whole blood using a blood component collection system comprising at least a blood component collection device, said method comprising the steps of:
- providing biological data relating to said source of whole blood;
- identifying a desired yield of said at least one predetermined type of blood component;
- associating a magnitude with each of one or more control parameters, said one or more control parameters being used in controlling said blood component collection system;
- said associating step comprising performing a first deriving step comprising deriving a magnitude for at least one of said one or more control parameters from said providing and identifying steps;
- inputting said magnitude of each of said one or more control parameters into said blood component collection system after said associating step;
- and
- performing a collection procedure on said blood component collection device using said inputting step to collect said desired yield of said at least one predetermined type of blood component from said source of whole blood;
- wherein:
- one of said one or more control parameters is an inlet flow to said blood component collection device and another of said one or more control parameters is a flow of anticoagulant into said blood component collection system, wherein said inlet flow comprises a flow of whole blood from said source of whole blood and said flow of anticoagulant, wherein said source of whole blood has a volume, wherein at least part of said flow of anticoagulant is provided to said source of whole blood, wherein an anticoagulant ratio is a ratio of said inlet flow to said flow of anticoagulant, and wherein an anticoagulant infusion rate is defined by said at least part of said flow of anticoagulant per said volume.
A method for collecting at least one predetermined type of blood component from a source of whole blood using a blood component collection system comprising at least a blood component collection device, said method comprising the steps of:
- providing biological data relating to said source of whole blood;
- identifying a desired yield of said at least one predetermined type of blood component;
- associating a magnitude with each of one or more control parameters, said one or more control parameters being used in controlling said blood component collection system;
- said associating step comprising performing a first deriving step comprising deriving a magnitude for at least one of said one or more control parameters from said providing and identifying steps;
- inputting said magnitude of each of said one or more control parameters into said blood component collection system after said associating step;
- and
- performing a collection procedure on said blood component collection device using said inputting step to collect said desired yield of said at least one predetermined type of blood component from said source of whole blood;
- wherein:
- said at least one of said one or more control parameters is a total procedure time, said performing a first deriving step comprising maximizing an inlet flow and minimizing said total procedure time.
A method for collecting at least one predetermined type of blood component from a source of whole blood using a blood component collection system comprising at least a blood component collection device, said method comprising the steps of:
- providing biological data relating to said source of whole blood;
- identifying a desired yield of said at least one predetermined type of blood component;
- associating a magnitude with each of one or more control parameters, said one or more control parameters being used in controlling said blood component collection system;
- said associating step comprising performing a first deriving step comprising deriving a magnitude for at least one of said one or more control parameters from said providing and identifying steps;
- inputting said magnitude of each of said one or more control parameters into said blood component collection system after said associating step:
- and
- performing a collection procedure on said blood component collection device using said inputting step to collect said desired yield of said at least one predetermined type of blood component from said source of whole blood:
- further comprising the steps of:
- providing a magnitude for each of said one or more control parameters before said identifying step;
- performing said collection procedure on said blood component collection device before said identifying step, using said inputting said magnitude step for a first time period, wherein said associating step is performed after expiration of said first time period.
