The medical oxygen reducer inhaler is designed to reduce the pressure in the cylinder to the set value, as well as to carry out aerosol therapy. The device is also used to connect ventilator equipment (artificial ventilation in the lungs) in the conditions of transportation of the injured or directly at the scene. The oxygen reducer is attached to the valve.
The device can be used for first aid in case of fires, gas pollution, smoke. The equipment is also used for asphyxia, oxygen starvation, to alleviate attacks of bronchial asthma. The device is safe to use, no special training is required for its use. The oxygen reducer can also be used by employees who do not have any qualifications.
In addition to reducing pressure, the device also helps to maintain it at an optimal level automatically. The oxygen reducer is attached to the cylinders with union nuts. Devices are divided according to working pressure, throughput. Reduceroxygen can be direct or reverse action. In the first case, the control valve is opened by gas pressure. In a reverse-acting gearbox, on the contrary, the valve closes. This model, it should be noted, is considered the most reliable and, in this regard, more common.
Reverse oxygen reducer is quite compact. Its relatively simple design includes two chambers. One of them - working - has low pressure, the second - high. There is a valve between them. It is acted upon by 2 springs through the membrane. The second chamber is connected to the cylinder, in connection with this, the pressure in these parts of the device is the same. The opening of the valve depends on the ratio with which the springs are compressed. The elasticity of one of them (in the low pressure compartment) is adjusted with a screw. It is unscrewed to loosen the spring and close the valve.
The low pressure chamber is connected to the gas burner via gas hoses and a valve.
If the oxygen consumption is greater than its supply, the pressure of the working chamber will decrease. At the same time, the pressure spring, acting on the diaphragm, deforms it. This will cause the valve to open slightly, which will provoke an increase in the flow of oxygen into the working chamber. A decrease in flow causes an increase in pressure. The compression of the spring in this case deforms the diaphragm in the other direction. As a result, the valve closes the through hole and reduces the flow of gas. Sooptimal pressure is maintained in automatic mode.
The oxygen reducer is equipped with two pressure gauges. Their serviceability must be checked before starting work when connecting the cylinder and the device. The pressure gauges must be at zero and must not move when turning the reducer.
It is forbidden to independently tighten the threaded connections of the device, due to the fact that the work is carried out under high pressure.
