The tube has a number of holes distributed in the longitudinal direction of the tube that form the vent openings

Such an extension can be produced easily and inexpensively, aaSerdea can already be installed Saaaelgefäee easy to convert.

According to a further development of the innovation, the air extraction openings have different sizes, in particular the size of the air extraction openings can essentially increase in the direction of the inner drawer of the extension In this way one can achieve that aas the different At least approximately the same amount of air is removed from areas along the extension

According to a further embodiment of the Heuerang is the part of the extension that has the air inlet openings outside the inner container «. Biesur part can e.g. at the Outer wall of the inner container run parallel to its axis

In the following, an execution game is based on the innovation closer to the drawing

The illustrated embodiment of the innovation contains an inner container 1 in perm a plastic bottle, whose beden with a relatively large tone, from a wire mesh spanned opening 2 is provided. Bas wire network is on Upper find of the inner container 1 by means of a flange 4 attached; which consists of ** »an annular groove 5 for receiving a has elastic ring 6 * About neck 8 of the bottle is used as Kxpiratioaslmft-Binlaß and is used when using the collection open the vessel with a hose, which the examined Person exhales through a mouthpiece or breathing mask.

The side wall of the inner container 1 has sehlitzfärmige Openings 9 on Ic near the neck 8 is an air intake port 10 arranged. At the end of the rare wall of the inner container 1 adjacent to the neck 8, there is a see annular recess 11, which is also for receiving a

elastic ring 12 is determined.

The annular groove 5, the recess 11, and the elastic rings 6 and 12 are used to attach a StQoK plastic hose 13, the diameter of which is significantly larger than that of the inner container 1.

As far as described, the expiratory air collecting vessel is known

According to the present innovation, the air extraction nozzle 10 does not simply open out at the bottom of the inner container 1, but rather it has an extension in the form of a hose 1 & amf, which can be attached to the inner end of the extraction nozzle 10, for example. In the illustrated embodiment, the hose 14 leads through a hole in the side wall of the inner container 1 and then runs in the direction of its axis 15 along its outer wall, to which it is attached in a suitable manner, e.g. by gluing, welding, by mounting brackets or the like. The tube can, for example, have an inside diameter of approximately 5 nm and has a number of holes 16 which are distributed in its longitudinal direction and of course can also be tolled in its circumferential direction. May be preferably takes the GrBiBe of the holes in the direction from Entnahiaestutzen 1Θ to the inner bath 17 iusaa open or closed) to back so that trad from all walks of UEM by the InBentfaum inner container 1 the bag 13 exhaled air collecting space formed about the same amount of air is removed.

The extension does not need to be outside the inner container to run, it can for example also consist of a stiff tube that protrudes into the interior of the inner container 1. However, the arrangement of the extension shown has proven to be special Proven to be useful and effective
