Abstract
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.
Claims20
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.
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.
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.
