Such a connecting element is, for example, be found in GB 2190969 A to.

or the like fasteners for ventilation hoses. 29823090 Ul are described for example in DE. Such a known, substantially Y-shaped design connection element opens into a further pipe section, wherein a non-slip surface of the connecting element has been proposed to facilitate the pushing on and dismounting of hoses.

In modern ventilators usually advised a greater number of tubes to be connected, with the individual tubes each with different functions are used and, therefore, separately to flow inside a tube. A rapid and error-free connection of such a tube with a plurality of different hoses is therefore in terms of patient safety is essential. Hose connectors are known in principle in different training. A hose connector with a plug part and an inner profile substantially complementary construction to the plug part socket part DE 3529052 Al, for example, can be seen. Such a design of always can be connected to each other only in a particular defined angular position and is thus less suitable as different torques have to be absorbed by the hose connection depending on the movement and position of the patient, which also in the sequence for use in a respirator exert respective torques to the tube, whereby undesired stresses are introduced.

The invention now aims to further develop a connection element of the type mentioned initially such that it, for example, a tracheal tube can be connected quickly and risk of confusion with the respective counterclaims circuits and to the secure connection allows an appropriate freedom of movement without that here the tight and secure connecting a plurality of different arranged tubes, each having a plurality of corresponding in the tube and opening into openings different distances will be affected. thus, it is intended both the sealing effect as well as the correct assignment of the individual tubes to the corresponding holes in the interior of a tube can be maintained in any position and a particularly simple connection of a plurality can be ensured confusable of different hoses for different gases or different measuring processes. To solve this problem connecting to the invention consists element, starting from a configuration in which is provided at least a first plug-shaped connecting member with at least two hose connections, whose plug-in part offset in the axial direction has radial openings, which are connected each with a hose connection, wherein at least one sleeve-shaped connecting member is provided to be rotated about the insertion axis receptacle of the male connection member having a wall in which also has radial openings the axial spacing of the radial apertures of the male connecting member corresponding axial intervals, between adjacent radial apertures and the axial end of the bush-shaped and / or plug-shaped connecting member the wall of the bush-shaped and plug-shaped connecting member relative to one another sealing ring or disc-shaped gasket having en substantially in the fact that the depth of insertion of the plug shaped link is limited by resilient stops and the resilient stops are designed as resilient locking members and engage with counterstops. Characterized in that plug-in parts of the invention are rotatably received in the socket-shaped connecting members and each having at least two hose connections of each plug-in part open out from each other via radial openings at different axial distances, the possibility is created, even upon rotation of the male connecting member, the correct opening of the respective radially exiting gas or radially withdrawn gas into a corresponding groove or a corresponding socket-side opening to be ensured. The structurally particularly simple embodiment of plug parts and socket-shaped connecting members allows interpreted respectively a male part and a corresponding female-shaped connecting member for two or more hose connections, and such in the case of a larger number of tube connections, and in particular for four or more hose connections for each two hose connections plug parts are selected with a first diameter corresponding to the outer diameter and for the respectively other plug-in parts of said first plug parts of different outer diameter, so that a reliable assignment of the respective terminals through a simple plug-in connection possible. For this purpose, the configuration is preferably made such that the number of at a first plug-shaped or exceeding the corresponding sleeve-shaped connecting member number of hose connections more plug-shaped or buchsenföπτiige connecting members are provided with different of the first links the outer and inner diameters for a. It can therefore which are used to measure the pressure and / or gas composition hose connections, comprising a plug part with a larger or smaller diameter than the diameter of the male part for the supply of gases and optionally gases which at the same time with a different pulse rate or consecutively are to be introduced at various locations may be selected.

In principle, it must be ensured that the respective radially opening out terminals are aligned in the axial direction with each other or can be brought in gas-tight connection when inserting the male part into the sleeve-shaped connecting member. To this end, the configuration is such that the depth of insertion of the male connection member is limited by resilient stops, at the same time are designed as resilient locking members, the resilient stops and engage with counterstops. By means of such spring-loaded stops the correct insertion position and on the other the same time allowing a fuse to extraction while maintaining the rotation of the plug in the socket thus firstly.

A particularly simple design, the connecting element can be designed so that the radial perforations are formed by annular grooves or open into annular grooves, which are preferably arranged as seals between adjacent annular grooves and O-rings of the same outside. In a particularly simple manner, the configuration is made according to the invention so that the sleeve-shaped connecting members supporting outlets are seen upstream of the gas supply line. A, Such a configuration makes it possible to remove the tubing between the gas supply line or also the corresponding measuring device and the tube, whereby a respectively required cleaning is greatly facilitated.

The invention is explained in more detail below reference to a schematically depicted in the drawings embodiment. In this Fig.l show a cross section of a plug part with two plugged hose ends and Figure 2 a cross section of a corresponding sleeve-shaped connecting member for use together with a connector according to Fig.l.
