Abstract

A blood component collection system with data manipulation and optimization capabilities. The system comprises a central database, a data manipulation device, and a communication subsystem connected to the central database and the data manipulation device, and one or more extracorporeal blood processing machines. The central database maintains records of total donation volumes contributed by a donor during selected time periods as communicated by the blood processing machine and as determined by the data manipulation device. The records comprise a total red blood cell donation volume and a total plasma donation volume.

8. The extracorporeal blood processing information management system of claim 7 wherein said estimated plasma donation volume comprises an actual whole blood donation volume reduced according to a minimum hematocrit.

9. The extracorporeal blood processing information management system of claim 6 wherein said estimated plasma donation volume comprises an actual whole blood donation volume reduced according to a minimum hematocrit.

10. The extracorporeal blood processing information management system of claim 9 wherein said estimated red blood donation volume comprises an actual whole blood donation volume reduced according to a maximum hematocrit.

11. The extracorporeal blood processing information management system of claim 10 wherein said calculated red blood cell donation volume comprises an actual whole blood donation volume reduced according to a known patient hematocrit and wherein said calculated plasma donation volume comprises an actual whole blood donation volume reduced according to a known donor hematocrit.

12. The extracorporeal blood processing information management system of claim 1 further comprising at least one extracorporeal blood processing machine in data communication relationship with said communication subsystem, said blood processing machine being capable of communicating data concerning a donation volume contributed by a donor.

13. An extracorporeal blood processing information management system comprising:

a central database; and

means for creating records of total donation volumes contributed by a donor, said donation volumes being volumes of fluid not returned to said donor, said records being maintained for a plurality of donations by said donor during selected time periods as communicated by said blood processing machine and as determined by said data manipulation device, said records being stored in said central database and comprising a total red blood cell donation volume and a total plasma donation volume for said plurality of donations.

14. The extracorporeal blood processing information management system of claim 13 wherein said total red blood cell donation volume comprises at least one actual red blood cell donation volume and at least one calculated red blood cell donation volume and at least one estimated red blood cell donation volume.

15. The extracorporeal blood processing information management system of claim 14 further comprising means for determining said calculated red blood cell donation volume from an actual whole blood donation volume reduced according to a known donor hematocrit.

16. The extracorporeal blood processing information management system of claim 15 further comprising means for determining said estimated red blood donation volume from an actual whole blood donation volume reduced according to a maximum hematocrit.

17. The extracorporeal blood processing information management system of claim 14 further comprising means for determining said estimated red blood donation volume comprises an actual whole blood donation volume reduced according to a maximum hematocrit.
