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.
Claims24
A method for preserving erythrocytes comprising the steps of:
- a. obtaining an erythrocyte concentrate;
- b. subjecting the erythrocyte concentrate to a gas system that includes xenon at a concentration that is greater than xenon gas that naturally occurs in the atmosphere;
- and,
- c. 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.
The method as defined in claim 17, wherein said container is positioned in a hermetically-sealed vessel equipped with a cover that is permeable to said gas mixture, said vessel is not permeable to said gas mixture.
An erythrocyte container system designed to preserving erythrocytes comprising a container that includes an erythrocyte concentrate, said erythrocyte concentrate in said container at a temperature of less than ambient temperature, said erythrocyte concentrate at least partially saturated with a gas system, said gas system including xenon gas at a concentration that is greater than xenon gas that naturally occurs in the atmosphere.
