A nonreturn valve () for a compact ventilation system (), includes a recoil membrane () and a holding element () for holding the recoil membrane () and for fastening the nonreturn valve () at a flow duct () of the compact ventilation system (). The recoil membrane () has at least one mechanical stabilizing section () for cooperating with at least one mechanical counter-stabilizing section () of the holding element () or of the flow duct () of the compact ventilation system (). At least one opening section () is provided for the defined movement of the recoil membrane () during the opening of the nonreturn valve () and a holding section () is provided for holding the recoil membrane () at a counter-holding section () of the holding element (). A compact ventilation system () is provided with such a nonreturn valve ().

Water filter device and housing

A self-locking T-piece connects an attachment to a breathing gas line. The self-locking T-piece has a line section (), a connection line () branching off therefrom, a movable valve body () with a valve disk (), and a valve seat (). The valve body () is prestressed by a spring () into a position to seal the connection line () against the line section (), with the valve disk in the valve seat, and moves out of the sealing position when connecting the attachment to the connection line. The valve body () is elastically deformable such that it can be advanced through the connection line () and the valve seat (), while undergoing elastic deformation, and returns to its original shape during the entry of valve disk () into the line section, in which it has a sufficient extension to be able to cover the valve seat for sealing.

Self-locking T-piece

A breathing tube connecting device is provided for connecting a breathing tube to at least two respirators. The breathing tube connecting device includes a base body with a breathing gas through duct embodied in the base body, a jacket body, which can be meshed with the base body in a positive-locking manner and thus encloses at least a part of the base body in a coaxial manner, and a transponder. The transponder is provided between the base body and the jacket body. The breathing gas through duct and the jacket body are embodied at least partly as a coupling section for a selective connection of the breathing tube to one of the at least two respirators.

Breathing tube connecting device

A device for releasing breathing gas establishes constant flow conditions for the breathing gas being discharged. An annular connection element () is provided between an outer part () and an inner part (), and a discharge gap () is formed between the connection element () and the outer part ().
