Functionally-closed, sterile blood processing solution system and method
View Patent ↗Delivering a blood processing solution to blood in a blood bag includes coupling a first tube to a vented spike at one end and to a Y-shaped tube connector at a second end. An in-line microbiotic barrier filter is coupled to the first tube between its ends. A second tube is coupled to a transfer bag at one end and to the Y-shaped tube connector at its other end. A third tube is coupled to the output of the Y-shaped tube connector and sealed at its distal end. The blood bag includes a fourth tube that is sealed at a distal end. The third tube is welded to the fourth tube using a sterile tubing welder, wherein a functionally-closed, sterile flow path through which the blood processing solution can flow into the blood bag is maintained.
1. A functionally-closed, sterile Y-type tube set comprising:
a vented spike coupled to a first end of a first tube;
a Y-shaped tube connector having a first and a second input and an output, wherein a second end of the first tube is coupled to the first input of the Y-shaped tube connector;
an in-line microbiotic barrier filter coupled between the first and second ends of the first tube, wherein a flow path extends from the first end to the second end of the first tube that passes through the microbiotic barrier filter;
a transfer bag coupled to a first end of a second tube, wherein a second end of the second tube is coupled to the second input of the Y-shaped tube connector; and
a third tube coupled to the output of the Y-shaped tube connector, wherein a second end of the third tube is sealed.
2. The functionally-closed, sterile Y-type tube set of claim 1 , wherein the inline microbiotic filter is a 0.2 micron IV filter.
3. The Y-type tube set of claim 1 , wherein the transfer bag is empty.
4. The Y-type tube set of claim 1 , wherein the transfer bag includes a wash solution.
5. A method for delivering a blood processing solution to a blood component present in a blood bag, the method comprising:
obtaining a functionally-closed sterile tube set comprising i) Y-type tube connector, (ii) a first tube providing a flow path extending from a vented spike at a first end of the first tube through an inline microbiotic filter to a second end of the first tube, the second end coupled to a first input of the Y-type tube connector, (iii) a transfer bag coupled to a second input of the Y-type tube connector, and (iv) a sealed output tube coupled to an output of the Y-type tube connector;
welding the sealed output tube to a sealed input tubing of a blood bag using a sterile tubing welder, wherein a functionally-closed, sterile flow path is maintained through which a blood processing solution can flow into the blood bag; and
inserting the vented spike into avid containing the blood processing solution to deliver the blood processing solution through the inline microbiotic filter and into a blood component in the blood bag.
6. The method of claim 5 , further comprising storing the treated blood component greater than 24 hours for use thereafter.
7. The method of claim 5 , wherein the in-line microbiotic barrier filter is a 0.2 micron IV filter.
8. The method of claim 5 , further comprising increasing the intracellular content of ATP and 2,3-DPG of the blood component as a result of delivering the blood processing solution to the blood component.
9. The method of claim 5 , wherein blood component comprises a red blood cell concentrate, the method further comprising increasing the intracellular content of adenosine triphosphate and 2,3-diphosphoglycerate of the red blood cell concentrate as a result of delivering the blood processing solution to the red blood cell concentrate.
10. The method of claim 5 , further comprising processing the blood and blood processing solution together using a functionally-closed, sterile cell processor.
11. The method of claim 5 , further comprising processing the blood and blood processing solution together using a functionally-closed, sterile centrifuge.
12. A blood processing system, comprising:
a Y-shaped tube connector having a first input, a second input, and an output;
a first tube comprising an in-line filter, the first tube coupled to the first input;
a transfer bag coupled to the second input; and
an output tube coupled to the output of the Y-shaped tube connector, the output tube having a sealed end;
a vented spike configured to be coupled to the first tube; and
a container comprising a blood processing composition, the container configured to be pierced by the vented spike.
13. The blood processing system of claim 12 , wherein the transfer bag is empty.
14. The blood processing system of claim 12 , wherein the transfer bag includes a wash solution configured to wash a blood product.
15. The blood processing system of claim 12 , wherein the blood processing composition comprises inosine, pyruvate, adenine, and a phosphate mixture.
16. The blood processing system of claim 15 , wherein the blood processing composition comprises between about 2 to 30 g/L inosine, between about 5 to 15 g/L pyruvate, between about 0.2 to 2 g/L adenine, and between about 10 to 30 g/L phosphate.
17. The blood processing system of claim 15 , wherein the blood processing system is packaged in a single container.
18. The blood processing system of claim 17 , wherein the container includes instructions for use of the blood processing system.
19. The blood processing system of claim 12 , wherein the in-line filter is a 0.2 micron filter.
20. The blood processing system of claim 12 , wherein the transfer bag is coupled to second input through a tube.
