Oxygen generator

摘要

The generator has an inlet (1) connected to a pressurized air source (2). An oxygen output line (5) is connected to a supply circuit for a respiratory tract of a user. A flow meter (13) is placed in the output line for supplying an electrical signal representing an oxygen flow transitioning in the outlet. A runaway circuit (15) has a solenoid valve (16) that operates in response to a signal derived from the electrical signal.
