Abstract

The invention relates to a respiratory mask comprising a mask body and an articulated connection piece that can be connected to a respiratory tube. On the mask body, at least one exhalation gap is located in the vicinity of a connection that holds the articulated connection piece. Preferably, the exhalation gap terminates in an umbrella-shaped outflow channel that runs away from the patient. Preferably, at least two components of the respiratory mask are interconnected without play.
