摘要：
An elbow (1), for a respiration mask for the artificial respiration of a patient, includes an angular tube (30), which defines a breathing gas duct (10), with a tube port (11) with an inlet opening (12) for connecting a breathing tube (7) and with a mask port (13) with an outlet opening (14) for connecting the respiration mask (9). The elbow also includes an anti-suffocation valve (18) and carbon dioxide expiration openings (19). The elbow (1) is able to be switched, while being able to be handled in a simple manner, in different open and closed states for the anti-suffocation valve (18) and the carbon dioxide expiration openings (19). The elbow (1) includes only one (a single) switching member (20) for activating and deactivating the anti-suffocation valve (18) and the carbon dioxide expiration openings (19).
