Abstract

Certain examples provide a blood collection system including an operator user interface to allow an operator to configure the system for a blood collection procedure from a donor. The system also includes a donor display, separate from the operator user interface, arranged in the system to be within view of the donor who is to donate via the system. The donor display is to display information and instruction to the donor. The information and instruction include a first indicator regarding a progress of the blood collection procedure for the donor and a second indicator including a visual instruction to the donor regarding the blood collection procedure. The system includes a processor and a memory. The processor is to execute instructions stored in the memory to process input from and provide output to the operator user interface and the donor display.

Claims

1. A blood collection system comprising:

an operator user interface to allow an operator to configure the system for a blood collection procedure from a donor;

a donor display, separate from the operator user interface, arranged in the system to be within view of the donor who is to donate via the system, the donor display to display information and instruction to the donor, the information and instruction comprising a first indicator regarding a progress of the blood collection procedure for the donor and a second indicator comprising a visual prompt for donor interaction in the blood collection procedure, the visual prompt dynamically generated based on obtained sensor feedback indicative of donor blood flow; and

a processor and a memory, the processor to execute instructions stored in the memory to process input from and provide output to the operator user interface and the donor display.

2. The system of claim 1, wherein the second indicator comprises a graphical representation of a fist.

3. The system of claim 2, wherein the second indicator comprises a graphical representation of a fist plus one or more bars to indicate at least one of a squeeze intensity and a squeeze frequency.

4. The system of claim 1, wherein the second indicator flashes at a variable rate based on a desired donor squeeze frequency.

5. The system of claim 1, wherein the second indicator changes color according to a desired donor squeeze intensity.

6. The system of claim 1, wherein a discrete completion symbol is displayed upon completion of blood collection procedure.

7. The system of claim 1, wherein the blood collection procedure comprises a plasmapheresis blood component collection procedure.

8. The system of claim 1, wherein the information and instruction are derived from collected sensor data regarding donor vein and blood pressure feedback and collected volume at the system.

9. The system of claim 1, wherein a target collection volume for the donor is provided on the donor display.

10. The system of claim 9, wherein the target collection volume corresponds to a value programmed into the blood collection system by the operator for the donor.

11. A tangible computer readable medium including executable program instructions which, when executed by a processor, cause the processor to provide:

an operator user interface to allow an operator to configure a blood collection system for a blood collection procedure from a donor;

a donor display, separate from the operator user interface, arranged in the blood collection system to be within view of the donor who is to donate via the blood collection system, the donor display to display information and instruction to the donor, the information and instruction comprising a first indicator regarding a progress of the blood collection procedure for the donor and a second indicator comprising a visual prompt for donor interaction in the blood collection procedure, the visual prompt dynamically generated based on obtained sensor feedback indicative of donor blood flow.

12. The computer readable medium of claim 11, wherein the second indicator comprises a graphical representation of a fist.

13. The computer readable medium of claim 12, wherein the second indicator comprises a graphical representation of a fist plus one or more bars.

14. The computer readable medium of claim 11, wherein the second indicator flashes according to a desired donor squeeze frequency.

15. The computer readable medium of claim 11, wherein the second indicator changes color according to a desired donor squeeze intensity.

16. The computer readable medium of claim 11, wherein a discrete completion symbol is displayed upon completion of blood collection procedure.

17. The computer readable medium of claim 11, wherein the blood collection procedure comprises a plasmapheresis blood component collection procedure.

18. The computer readable medium of claim 11, wherein the information and instruction are derived from collected sensor data regarding donor vein and blood pressure feedback and collected volume at the blood collection system.

19. A method for computer-assisted blood collection from a donor, the method comprising:

adaptively processing measured data regarding donor blood flow and collected blood component volume from an ongoing blood collection procedure at a blood collection device;

determining at least one of a desired donor hand squeeze intensity and a desired donor hand squeeze frequency based on the processed data;

generating a graphical indicator based on the at least one of the desired donor hand squeeze intensity and the desired donor hand squeeze frequency to instruct the donor regarding the at least one of donor hand squeeze intensity and donor hand squeeze frequency to facilitate the blood collection procedure; and

displaying the graphical indicator to the donor via a donor display arranged to be viewable by the donor during the ongoing blood collection procedure.

20. The method of claim 19, wherein the graphical indicator animates to instruct the donor regarding at least one of the desired donor squeeze frequency and the desired donor squeeze intensity.

21. The method of claim 19, wherein the graphical indicator comprises a graphical representation of a fist displayed alone or in conjunction with one or more secondary graphical indicators.

22. The method of claim 19, wherein the measured data includes data regarding donor vein and blood pressure feedback collected from the donor by one or more sensors.

23. The method of claim 19, further comprising displaying a target collection volume for the donor on the donor display.

24. The method of claim 19, wherein the target collection volume corresponds to a value programmed into the blood collection system by the operator for the donor.
