  • Patent number: 6267745
    Abstract: A confined air tube is intended to be placed into in-line communication with the transfer tubing of a blood processing system. The confined air tube provides an incremental volume of air, which keeps the transfer tubing from collapsing and sticking together during heat sterilization. After sterilization, the confined air tube accommodates conveyance of a blood component into an associated downstream transfer container. The confined air tube can also receive air vented from the transfer container, so that the blood component can undergo further processing or be stored in an air-depleted environment within the transfer container.

  • Patent number: 5906915
    Abstract: The present invention provides an improved aqueous solution for suspending and storing red blood cells. The solution includes sodium citrate, a combination of sodium biphosphate and sodium phosphate dibasic, adenine, and mannitol. The solution is formulated at a low osmolarity and has a physiological pH of approximately 7.4. The solution simultaneously maintains stored red cells ATP and 2,3-BPG. Also disclosed is a method for storing red blood cells comprising adding an anticoagulant with a reduced citrate concentration compared to a CPD solution comprising 26.3 g/l, sodium citrate and 3.28 g/l citric acid hydrous to whole blood, separating the red cells and adding a storage solution comprising sodium citrate, sodium diphosphate, sodium phosphate dibasic, adenine and mannitol.
