The working principle and usage of buoy oxygen inhaler.

working principle

The role of the oxygen inhaler is to provide a continuous constant pressure and flow of oxygen for the patient to use. The bottle-inserted oxygen inhaler uses its own decompression device to reduce the high pressure in the oxygen bottle (15Mpa pressure when the bottle is full) to a low pressure (0.2~0.2Mpa) suitable for human use, and then output to the human body after being moistened by water. . The wall-plug oxygen inhaler does not need to be decompressed because the input pressure is 0.2~0.4Mpa, and it can be directly output to the human body.

How to operate

1. Add distilled water to the humidification cup. The water level in the bottle should not be higher than the upper water line, but it should not be lower than the lower water line. It is forbidden to use normal saline instead.

2. Screw the large nut of the inhaler on the outlet joint of the oxygen cylinder valve, so that the pressure gauge and flowmeter are vertically upward.

3. Before supplying oxygen, insert the oxygen suction tube into the oxygen delivery connector, and then turn the flow adjustment switch counterclockwise to open the source, so that the floating ball slowly rises (the scale line aligned with the upper plane of the floating ball is the flow reading, and the unit is L/min ), the oxygen supply can be adjusted as needed.

4. During the oxygen supply process of the inhaler, if the water in the inhaler bottle is lower than the water line, the flow adjustment switch should be closed in time, the humidification bottle should be unscrewed, and distilled water should be added according to the requirements of the first item of this item. Screw on the inhaler bottle and continue to supply oxygen.

5. When the inhaler is not in use, the air source of the inhaler should be turned off; if it needs to be removed, hold the inhaler with your hand and remove it after the operation (the unlocking method of different oxygen supply terminal sockets shall be explained by the engineering installation unit), and then After pouring out the water in the bottle for cleaning and disinfection, store it in a non-corrosive and well-ventilated room).
