Abstract
The object of the invention is to provide a novel reservoir assembly for providing a cardioplegic solution and a method for manufacturing the same. An aspect of the invention is to provide a reservoir assembly for providing a cardioplegic solution, comprising a multi-chamber reservoir; a gas-impermeable outer package packaging the multi-chamber reservoir; an oxygen detection agent and a deoxygenation agent in a space part between the multi-chamber reservoir and the outer package, wherein the deoxygenation agent neither generates nor absorbs carbon dioxide, wherein the multi-chamber reservoir comprises at least a first chamber, a second chamber, and a first separator wall that separates the two chambers, the first chamber holds a first medical liquid, the second chamber holds a second medical liquid containing bicarbonate ions, one or both of the first medical liquid and the second medical liquid contains potassium ions, the cardioplegic solution comprises the first medical liquid and the second medical liquid, and the cardioplegic solution contains bicarbonate ions of 5 to 20 mEq/L and potassium ions of 5 to 35 mEq/L. Another aspect of the invention is to provide a method for manufacturing the reservoir assembly for providing a cardioplegic solution.
