Abstract
This disclosure relates to a blood processing and preservation system. Apparatus of the system comprises a primary collection bag, a blood collection tube connected to the bag and adapted to draw a unit of blood from a person and feed the blood into the bag, and a harness connected to the bag for conducting solutions and blood components into and out of the bag. The harness includes a first tube for removing at least one blood component from the bag while retaining another component, a second tube for moving a cryoprotective solution into and out of the bag, a third tube for conducting a wash solution into and out of the bag, and identification on the bag. The foregoing apparatus is usable in a blood system including the method steps of collecting a unit of blood from a person and delivering the blood to the collection bag, processing the blood to separate the components and removing the components except for the red blood cells from the bag, preparing the red blood cells for freezing by conducting a cryoprotective solution into the bag and mixing this solution with the red blood cells, preserving the red blood cells by freezing, subsequently washing the red blood cells by conducting a wash solution and the cells into and out of the bag, and delivering the cells in the same collection bag to a recipient. While the foregoing method may be used in a homologous blood system where the recipient is not the donor, it is especially suited for use in an autologous blood system where the blood is reinfused in the person who furnished the blood, and the identification on the bag assures the recipient that he/she is receiving his/her own blood. Other blood components, such as the plasma, may also be preserved by freezing.
