  • Patent number: 10123528
    Abstract: A method for preserving erythrocytes comprising the steps of obtaining an erythrocyte concentrate; subjecting the erythrocyte concentrate to a gas system that includes 65% to 100% by volume and optionally one or more ballast gases from 0% to 35% by volume; and, maintaining the erythrocyte concentrate that has been subjected to the gas system at a temperature that is above the freezing point of the erythrocyte concentrate and up to a temperature of about 30° C.

  • Patent number: 5611997
    Abstract: An apparatus for producing blood component products. In one embodiment, a plurality of a predetermined type of blood component is harvested from a source of whole blood. At least two on-line yield determination techniques are utilized to determine the yield of the harvested blood components. One is a predetermined yield prediction technique and the second is a predetermined yield monitoring technique, each of which are individually calibrated in relation to a predetermined off-line yield determination technique. The predetermined yield prediction and monitoring techniques each provide the yield of the harvested blood components and each is then utilized to provide a determined yield. Consequently, when the harvested blood components are packaged the determined yield may be associated therewith, thereby providing a blood component product.
