    Abstract: A blood purification device includes a chamber, a liquid feed line, an air introduction unit, a liquid level adjustment unit, and a control unit. The chamber is provided on a blood circuit for extracorporeally circulating patient's blood and introduces purified plasma obtained by purifying plasma separated by a plasma separator provided on the blood circuit, or a replenishing liquid for replenishing the plasma separated by the plasma separator, into the blood circuit. The liquid feed line is capable of sending the purified plasma or the replenishing liquid to the chamber. The air introduction unit is capable of introducing air into the liquid feed line. The liquid level adjustment unit is capable of adjusting a liquid level height in the chamber. At the end of blood purification treatment, the control unit performs a liquid recovery process for sending the purified plasma or the replenishing liquid to the chamber via the liquid feed line while introducing air into the liquid feed line by the air introduction unit and maintains the liquid level height in the chamber at a predetermined liquid level height by the liquid level adjustment unit.

    Abstract: The present disclosure relates to various aspects of a procedure for reducing the carbon dioxide content in blood during the treatment of patients. A first aspect of the present disclosure relates to a buffer solution for use in reducing the carbon dioxide content in the blood when treating a patient suffering from pulmonary insufficiency or the complete failure of lung function, wherein the fluid is in gas exchange with a portion of the patient's blood conducted through an extracorporeal circuit. The first aspect of the present disclosure further relates to an apparatus for the extracorporeal reduction of the carbon dioxide content in the blood using said buffer solution. A second aspect of the present disclosure relates to a system for extracorporeal blood treatment, likewise using said buffer solution and the apparatus, and furthermore to a treatment apparatus for extracorporeal blood treatment comprising the aforementioned system. A third aspect of the present disclosure relates to a functional unit for performing extracorporeal blood treatment, a blood-guiding apparatus for interacting with the functional unit for performing an extracorporeal blood treatment using the aforementioned buffer solution, which comprises a blood treatment element, wherein the blood treatment element is the aforementioned apparatus for the extracorporeal reduction of the carbon dioxide content in the blood. In a fourth aspect, the present disclosure relates to a treatment system comprising the aforementioned apparatus for the extracorporeal reduction of the carbon dioxide content in blood as well as a balancing device. In a fifth aspect, the present disclosure relates to a treatment system comprising the aforementioned apparatus for the extracorporeal reduction of the carbon dioxide content in blood as well as a means for reducing the pressure of the aforementioned buffer solution used in said treatment system.
