Devices for the preparation of depleted blood products that provide oxygen, carbon dioxide, or oxygen and carbon dioxide depletion are described. The depletion device (100) comprises a housing (103), one or more liquid chambers (101), and one or more depletion chambers (102). A gas permeable barrier (107) separates the liquid chamber from the depletion chamber. The depletion chamber contains a depletion medium (106), such as a combination of solid O 2 and CO 2 sorbents. The depletion chamber may also include a gas inlet and a gas outlet through which a depleted gas such as argon enters and exits the device. The liquid chamber may include a flow control mechanism (108) that induces liquid flow relative to the gas permeable barrier. In addition, a device for supplementing oxygen and other gases to an anaerobic blood product is described. |
