Oxygen supplying device for respiratory mask, has electronic controller controlling stop valve with respect to pressure in temporary storage, and relief valve releasing pressure when pressure exceeds maximum permissible value

摘要

The device has a compressed oxygen tank connected to a temporary storage by a controllable stop valve (34). An impulse respiration controller is attached to the stop valve. An electronic controller (18) controls the stop valve with respect to pressure prevailing in the temporary storage. A relief valve is arranged between the storage and a regulator to release the pressure, when the pressure in storage exceeds a maximum permissible value.
