Abstract
This invention relates to a feeding apparatus for breathing masks that allows food and drink intake when the mask is in use, does not reduce the wearer's field of vision, requires little space, and is protected from dirt or other contamination. It is the problem of this invention to provide a feeding apparatus for breathing masks that does not reduce the wearer's field of vision, is protected from dirt or other contamination and allows for contamination-free insertion of a drinking cannula, if required. The problem of the invention is solved by placing a pivoting check valve (1) that can be closed using a sealing cap (5) and tightly encompasses a hollow axle (2) in a fitting 4 on the outside of the breathing mask. The hollow shaft (2) of the feeding apparatus is equipped with a hose and mouthpiece (3) on its end inside the breathing mask.
