A device (1) for removal of gas from a respiratory circuit comprises a first subsection (2) for connection to an inhalation branch of a respirator system, a second subsection (3) for connection to an exhalation branch of the respirator system, and a third subsection (4) with a tube connection opening (5) for insertion of a tube adapter (17), wherein the first subsection opens into the third subsection via a first opening (6), and the second subsection opens into the third subsection via a second opening (7). The device further comprises a gas removal tube (8) which stretches from an opening (9) in a wall (10) of the third subsection to a first gas removal tube end (12) that has a removal opening (11) extending into the third subsection, so that when the tube adapter is plugged in, the removal opening is essentially concentric with an opening (18) in the tube adapter, and the first end, relative to a direction (16) in which exhaled respiratory gas primarily exits from the opening in the tube adapter when the device is used, is arranged underneath an edge (13) of the first opening and an edge (14) of the second opening. The first end has an end face (25) that connects an edge (24) of the first end (12) which delimits an outer wall (8a) of the gas removal tube (8), to an inner wall (8b) of the gas removal tube (8) 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°. |
