| 摘要 |
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°. |

1. A device for removal of gas from a respiratory circuit, the device comprising:
a first subsection for connection to an inhalation branch of a respirator system; a second subsection for connection to an exhalation branch of the respirator system; a third subsection with a tube connection opening for insertion of a tube adapter, wherein the first subsection opens into the third subsection via a first opening and the second subsection opens into the third subsection via a second opening; and a gas removal tube extending from an opening in a wall of the third subsection into the third subsection, the removal tube having a first end having a removal opening, so that when the tube adapter is inserted, the removal opening is arranged essentially concentrically to an opening formed in the tube adapter and the first end is arranged under an edge of the first opening and an edge of the second opening, in relation to a direction in which exhaled breathing gas is predominantly discharged from the opening, in the tube adapter when the device is used, wherein the first end has an end face, which connects an edge of the first end, which said edge defines an outer wall of the gas removal tube, with an inner wall of the gas removal tube, which said inner wall surrounds the removal opening, wherein at least 40% of the end face is made funnel-shaped with an opening angle between 130° and 170°. |
