Single collection bag blood collection system, method and apparatus
A blood or blood component collection and processing system, apparatus and method are disclosed. One embodiment includes a vascular access device and a blood collection container having a blood inlet and first and second blood component outlets. The outlets are located at opposite ends of the container, and a blood flow conduit extends between the vascular access device and collection container. The collection container is free of attachment to other blood collection containers when in an initial collection configuration at the time of collection.
1. A method of processing one or more blood components using a blood processing system, the blood processing system including a red cell collection container having a cell inlet and a cell outlet with the cell inlet spaced from the cell outlet, a red cell flow conduit having one end defining a red cell inlet and another end in fluid communication with the red cell collection container, the another end attached directly to the cell inlet of the red cell collection container, and a tubing loop separate from the red cell flow conduit and having one end in fluid communication with the interior of the red cell container, the one end attached directly to the cell outlet of the red cell collection container, and another end in fluid communication with red cell flow conduit at a junction between the ends of the red cell flow conduit, the method comprising:
flowing a red cell component from a collection container into the red cell collection container through the red cell flow conduit,
flowing contents of the red cell collection container from the red cell collection container into the tubing loop; and
flowing the contents of the red cell collection container from the tubing loop into the red cell flow conduit and mixing the contents with the red cell component from the collection container.
2. The method of claim 1 , wherein the red cell collection container contains certain ingredients of a red cell preservative solution.
3. The method of claim 2 , wherein a processing container is connected to and in fluid communication with the red cell flow conduit and contains other ingredients of the red cell preservative solution, and the method further comprises flowing the red cell component from the collection container through the processing container before flowing the red cell component into the red cell collection container.
4. The method of claim 1 , wherein the red cell flow conduit includes a leukocyte reduction filter, the red cell collection container contains certain ingredients of a red cell preservative solution, and the method further comprises flowing the certain ingredients from the red cell collection container through the leukocyte reduction filter to wet the leukocyte reduction filter before flowing the concentrated red cell component through the leukocyte reduction filter.
5. The method of claim 4 including filtering the red cells through the leukocyte reduction filter after the filter is wetted by the certain ingredients.
