Abstract

Claims (47)

1. A method of collecting plasma, comprising:

introducing whole blood from a donor to a separator;

combining anticoagulant with the whole blood from the donor;

separating whole blood from the donor into a plasma product and a second blood component comprising red blood cells;

sending the plasma product to a plasma product collection container;

receiving input from an operator;

scanning a bar code associated with the donor; and

determining with a controller a total blood volume for the donor based at least in part on donor weight and donor height;

displaying on a touch screen a parameter which identifies the donor;

receiving a confirming user input via the touchscreen, and,

in response to the confirming user input, operating a plurality of 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 method of claim 1 , wherein total blood volume is further determined by the controller based on donor gender.

3. The method of claim 1 , wherein the parameter which identifies the donor comprises the donor's name.

4. The method of claim 1 , further comprising determining a target volume for plasma product and/or raw plasma collection based at least in part on the total blood volume for the donor.

5. The method of claim 4 , further comprising, after controlling the system to operate one of the plurality of draw phases, establishing 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 controlling 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.

6. The method of claim 1 , further comprising determining the target volume based further on a hematocrit of the donor.

7. The method of claim 1 , further comprising determining the donor's total blood volume before whole blood is withdrawn from the donor during a donation.

8. The method of claim 1 , wherein the method is configured to operate at least three draw and return phases during a donation.

9. A method of collecting plasma, comprising:

receiving input from an operator at a touch screen;

scanning a bar code associated with a donor to receive personal information about the donor;

displaying on the touch screen a parameter which identifies the donor;

receiving a confirming user input via the touchscreen;

determining a body mass for the donor based at least in part on donor weight and donor height using a controller; and

controlling a blood separator to operate a plurality of draw and return phases to withdraw whole blood from a donor, combine anticoagulant with the whole blood, and separate the whole blood into a plasma product and a second blood component and to return the second blood component to the donor, 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.

10. The method of claim 9 , wherein the body mass is further determined based on donor gender.

11. The method of claim 9 , wherein the parameter which identifies the donor comprises the donor's first name, last name, and date of birth.

12. The method of claim 9 , further comprising determining, using the controller, a target volume for plasma product and/or raw plasma collection based at least in part on the body mass for the donor.

13. The method of claim 9 , further comprising, after controlling the system to operate one of the plurality of draw phases, establishing using the controller 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 controlling 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.

14. The method of claim 9 , wherein the controller determines the target volume based further on a hematocrit of the donor.

15. The method of claim 9 , 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 method of claim 9 , wherein the controller is configured to operate at least three draw and return phases during a donation.

17. A method of collecting plasma, comprising:

separating whole blood into a plasma product and a second blood component comprising red blood cells;

sending the plasma product to a plasma product collection container;

introducing the whole blood from a donor to a separator;

combining anticoagulant with the whole blood from the donor;

receiving input from an operator;

scanning a bar code associated with the donor;

determining a target volume for plasma product and/or raw plasma collection based at least in part on donor weight and donor height;

displaying on a touch screen data which identifies the donor;

receiving a confirming user input via the touchscreen; and

operating a plurality of 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.

18. The method of claim 17 , wherein the target volume for plasma product and/or raw plasma collection is based further on donor gender.

19. The method of claim 17 , wherein the data which identifies the donor comprises the first and last name and date of birth.

20. The method of claim 17 , further comprising determining the target volume based further on a hematocrit of the donor and before whole blood is withdrawn from the donor during a donation.

21. The method of claim 17 , wherein the operating step comprises operating at least three draw and return phases during a donation.
