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.

A method useful in delivering a blood processing solution to blood present in a blood bag, the method comprising:
- coupling a first end of a first tube to a vented spike and a second end of the first tube to a first input of a Y-shaped tube connector;
- coupling an in-line microbiotic barrier filter 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;
- coupling a first end of a second tube to a transfer bag and a second end of the second tube to a second input of the Y-shaped tube connector;
- coupling a first end of a third tube to an output of the Y-shaped tube connector;
- sealing a second end of the third tube;
- providing instructions to seal a second end of a fourth tube that is coupled at a first end to the blood bag;
- and
- providing instructions to weld the third tube to the fourth tube using a sterile tubing welder.
A system useful in delivering a blood processing solution to blood present in a blood bag, the system comprising:
- 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;
- and
- indicia instructing a user to weld the third tube to a sealed blood bag tube using a sterile tubing welder and thereby maintain a functionally-closed, sterile flow path through which the blood processing solution can flow into the blood bag.
