Mellan skxkten bildas parallella, genomgående kanaler, genom vllka patientens ut- och inandningsluft är avsedd att strömma. Stutsen 90 sträcker sig i huvudsak över höljets hela utsträcknlng vlnkelrätt mot den nämnda axellinjen x. och stutsen 9b är lämpllgeo utformad på stutsen 9c.The sockets 9a-c of the exchanger 9 are formed in the same strength as a preferably plastic-containing casing containing a circular-cylindrical insert 10. The insert 10 consists of a plurality of concentric, corrugated layers of paper or the like, which are treated with hydroscopic material. Between the layers, parallel, continuous channels are formed, through which the patient's exhaled and inhaled air is intended to flow. The stub 90 extends substantially over the entire extension of the housing perpendicular to the said axis x and the stub 9b is suitably formed on the stub 9c.
