Abstract

A system and method for collecting plasma includes drawing whole blood from a donor, combining anticoagulant with the whole blood from the donor, separating the whole blood into a plasma product and a second blood component and sending the plasma product to a collection container. A controller receives parameters over a network from a remote computer, receives a user input to confirm the a parameter and/or procedure, determines a target volume for plasma product and/or raw plasma based on the parameters and, in response to confirming the donor, controls the system to collect the plasma using draw and return phases.

First claim

The invention claimed is:

1. A system for collecting plasma, comprising:
a venipuncture needle configured to draw whole blood from a donor;
a blood separator configured to separate whole blood into a plasma product and a second blood component comprising red blood cells, the blood separator having a plasma output port coupled to a plasma line configured to send the plasma product to a plasma product collection container;
a donor line fluidly coupled to the venipuncture needle configured to introduce the whole blood from the donor to the separator, flow through the donor line being controlled by a first pump;
an anticoagulant line coupled to an anticoagulant source, the anticoagulant line configured to combine anticoagulant with the whole blood from the donor, flow through the anticoagulant line being controlled by a second pump,
a touchscreen configured to receive input from an operator; and
a controller configured to control operation of the system, the controller configured to receive parameters for a plasma collection procedure over a network from a remote computer, the remote computer comprising a donor management system by which a donor is screened prior to a donation and donor records are managed, to receive a user input via the touchscreen to confirm at least one of the parameters and/or the procedure, to determine a target volume for plasma product and/or raw plasma which is based at least in part on at least one of the parameters received over the network from the remote computer and, in response to confirming the at least one of the parameters and/or the procedure, to control the system to operate at least three draw and return phases to withdraw whole blood from a donor and separate the whole blood into the plasma product and the second blood component and to return the second blood component to the donor.

2. The system of claim 1 , wherein the parameters comprise an image of the donor, the controller configured to display the image on the touchscreen and to receive the user input from the touch screen to confirm the donor.

3. The system of claim 1 , wherein the parameters comprise a donor identifier, wherein the system further comprises a scanner configured to scan a code associated with a donor.

4. The system of claim 3 , wherein the scanner is configured to scan the code from a wristband worn by the donor.

5. The system of claim 3 , wherein the parameters comprise at least one data unique to or characteristic of the donor, wherein the controller is configured to display the at least one data unique to the donor and prompt the user to confirm the donor is associated with the data unique to the donor.

6. The system of claim 5 , wherein the at least one data unique to or characteristic of the donor is a social security number or a birth date.

7. The system of claim 1 , wherein the controller is configured to determine the target volume for plasma product and/or raw plasma by receiving the target volume for plasma product and/or raw plasma as one of the parameters from the remote computer.

8. The system of claim 7 , further comprising the remote computer, wherein the remote computer is configured to calculate the target volume for plasma product and/or raw plasma based on at least two of weight, height, hematocrit and gender of the donor.

9. The system of claim 1 , further comprising the remote computer and a weight scale coupled to one of the remote computer and the controller, wherein at least one of the remote computer and the controller is configured to receive the weight of the donor from the weight scale, wherein the target volume for plasma product and/or raw plasma is determined based at least in part on the weight from the weight scale.

10. The system of claim 1 , wherein the controller determines the target volume for plasma product and/or raw plasma by calculating the target volume for plasma product and/or raw plasma and wherein the controller is local to and coupled to the blood separator.

11. The system of claim 1 , wherein the donor parameters received electronically from the remote computer comprise a donor weight, wherein the controller is configured to determine the target volume for plasma product and/or raw plasma based at least in part on the donor weight.

12. The system of claim 11 , wherein the donor parameters received electronically from the remote computer comprise a donor hematocrit, wherein the controller is configured to determine the target volume for plasma product and/or raw plasma based at least in part on the donor hematocrit.

13. The system of claim 12 , wherein the controller is configured to determine a target volume for plasma product based on the donor's total blood volume and the donor's plasma volume.

14. The system of claim 13 , wherein the controller is configured to determine the donor's total blood volume based on the weight and height of the donor.

15. The system of claim 14 , wherein the controller is configured to determine the donor's total blood volume before whole blood is withdrawn from the donor during a donation.

16. The system of claim 15 , wherein the controller is configured to determine the target volume for plasma product comprising raw plasma and anticoagulant, wherein the target volume for plasma product is determined prior to withdrawing the whole blood from the donor based at least in part on an anticoagulant ratio, the donor's weight and the donor's hematocrit.

17. The system of claim 1 , further comprising a reservoir separate from the blood separator for receiving concentrated red blood cells.

18. The system of claim 1 , wherein the controller is further configured to, after controlling the system to operate a draw phase and a return phase, establish an updated value of hematocrit of the donor and a new target volume for plasma product and/or raw plasma based on the updated value of hematocrit, and to control the system to operate a subsequent draw and return cycle, whereby the donor's changing hematocrit is taken into account in calculating the new target volume for plasma product and/or raw plasma.

19. The system of claim 1 , wherein the parameters received by the controller comprise at least a donor's weight, height, sex and hematocrit, the controller to determine the target volume for plasma product and/or raw plasma based at least in part on the weight, height, sex and hematocrit and to control the system to operate the draw and return phases until the target volume is reached.

20. The system of claim 1 , further comprising the remote computer, wherein the remote computer is configured to calculate the target volume based on at least a donor's weight, height, sex and hematocrit, wherein the controller is configured to determine the target volume by receiving the target volume from the remote computer.

21. The system of claim 1 , wherein the controller is configured to receive at least a donor's weight, height and hematocrit and to determine the target volume for plasma product comprising raw plasma and anticoagulant, wherein the target volume for plasma product is determined prior to withdrawing the whole blood from the donor based at least in part on an anticoagulant ratio, the donor's weight, height and the donor's hematocrit, the controller configured to then control the system to operate the draw and return cycles.

22. The system of claim 21 , wherein the controller is configured to determine the target volume for plasma product based on the donor's total blood volume and the donor's plasma volume.
