摘要： A method and apparatus for maximizing the total amount of blood processed during an apheresis procedure by optimizing the concentration of anticoagulant in a donor/patient and the associated extracorporeal tubing set is provided. A simplified model of anticoagulant accumulation in a donor/patient's body is used to calculate an optimal anticoagulant infusion rate profile to the donor/patient during a blood processing procedure. A maximum acceptable anticoagulant concentration in the donor/patient acts as an upper limit on the rate at which anticoagulant may be infused to the donor/patient using the optimized infusion rate profile. A minimum acceptable anticoagulant level acts as a lower limit in optimally controlling the anticoagulant concentration in the extracorporeal tubing set. Both the maximum acceptable anticoagulant level in the donor/patient and the minimum acceptable anticoagulant level in the extracorporeal tubing set may be customized for a specific donor/patient thereby allowing the optimized infusion rate profile and the extracorporeal tubing set anticoagulant concentration to be customized for the specific patient.

摘要： An apparatus for producing blood component products. In one embodiment, a plurality of a predetermined type of blood component is harvested from a source of whole blood. At least two on-line yield determination techniques are utilized to determine the yield of the harvested blood components. One is a predetermined yield prediction technique and the second is a predetermined yield monitoring technique, each of which are individually calibrated in relation to a predetermined off-line yield determination technique. The predetermined yield prediction and monitoring techniques each provide the yield of the harvested blood components and each is then utilized to provide a determined yield. Consequently, when the harvested blood components are packaged the determined yield may be associated therewith, thereby providing a blood component product.

摘要： A blood component collection system 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 parameter. 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.

摘要： A method for processing blood in an apheresis system is disclosed. The present invention includes selecting a packing factor for separated blood component types in the separation stage(s) of a blood processing vessel. A packing factor is a number that reflects the degree with which the blood component types are packed together in the separation stage(s) and is dependent at least upon the rotational speed and the flow rate into the blood processing vessel. The method further includes providing an apheresis system and operating it under conditions to separate the blood into a plurality of blood component types and achieve the selected packing factor.
