Using the switch 41, it is possible; ::, manually or automatically using the device 42 to control arbitrary deep breathing intervals. If the inhalation time exceeds the expiration time, the time comparison device 26 is activated and a signal is sent to the signaling device 27. If the camera 11 is empty, the determination means 18 sends a signal to the valve control devices 23, 24 2.2. Connect ™ M pipe 21 with the atmosphere and, therefore, instantaneously lower the pressure of B chamber 11 to atmospheric. The operation of the synchronization means 25 is essentially a function of the operation of the pressure sensor 43, which turns on the alarm device 8, at Gj y-iae, if the maximum inhalation pressure has been exceeded. The pause device 28 is set to approximately 15 seconds and, if during this time the mechanism does not work correctly, the alarm device 9 is triggered. In case of low oxygen pressure, the alarm device 10 is activated. Air can be supplied to the spray gun 32 from pipe 44 connected to the main gas bungle 1 or from an additional gas source 31, and gas from one source from another source is supplied by a safety valve 4. Thus, the gas B is dispensed from different sources, which increases the reliability of the apparatus. Formula 1 and 1.
