A housing for a solid or fluidal substance for the removal of an undesired respiratory gas component of a respiratory gas flow and an arrangement for ventilating lungs of a subject

摘要

A housing (19) for a solid or fluidal substance to remove an undesired respiratory gas component of a respiratory gas flow is disclosed herein. The housing includes a space (30) receiving the substance and a wall (31) surrounding part of the space. The housing also includes a first separator (35) surrounding part of the space allowing the gas flow but preventing the substance escaping and a second separator (36) surrounding part of the space allowing gas flow but preventing the substance escaping. One of the first separator and the second separator allows the respiratory gas flow to the space and the remaining one of the first separator and the second separator lets the respiratory gas flow from the space. The housing further includes a limiter (38) between the first and second separator for limiting a movement of the substance inside the space. An arrangement for ventilating lungs of a subject is also provided.
