Abstract
A respiratory circuit gas removal device (1) has a inhalation branch subsection (2), a exhalation branch subsection (3) and a tube connection subsection (4), with a tube connection opening (5) for a tube adapter (17). The inhalation subsection connects to the tube subsection via a first opening (6), and the exhalation subsection opens into the tube subsection via a second opening (7). A gas removal tube (8) extends from the tube subsection to a removal opening (11), essentially concentric with a tube adapter opening (18). A tube end face (25) connects an edge (24) of a first end (12), which delimits an outer wall (8a) of the gas removal tube, to an inner wall (8b) of the gas removal tube surrounding the removal opening (11). At least 40 percent of the end face (25) is in a funnel shape and has an opening angle (15) between 130° and 170°.
