Abstract:
1. An oxygen supply device comprising: an oxygen source; an oxygen mask; a pressure sensor arranged in said oxygen mask; a breathing regulator arranged between said oxygen source and said oxygen mask, said breathing regulator comprising an electronic controller; an oxygen sensor arranged downstream of said breathing regulator wherein said breathing regulator and said oxygen sensor are arranged in an integral component; a breathing activity means for registering breathing activity of a mask user, said breathing activity means comprising a sensor for registering an air mass flow arranged downstream of said breathing regulator wherein said breathing activity means for registering breathing activity forms an integral constituent part of said oxygen sensor; a control device having a display function, wherein said oxygen sensor has a signal connection to said control device and said control device is connected to said pressure sensor arranged in said oxygen mask and connected to said breathing activity means, said control device indicating a deficient supply of oxygen at said oxygen sensor via said display function and said control device comprising a regulating unit for regulating said breathing regulator; and an exhalation valve comprising a valve element that has an open position to form a flow path from an internal space of said mask body to an outlet and a bias means including a line connecting an internal space of said integral component to said exhalation valve such that said valve element is moved to a closed position by fluid pressure prevailing in said internal space of said integral component.
