1、The oxygen inhaler has accurate flow, simple operation and convenient to use. 2、The oxygen pressure regulator converts high‑pressure oxygen into low‑pressure oxygen, and inhales it at low pressure. 3、Made of high‑quality materials, the scale is clearly visible, not easy to rust, and has a longer service life. 4、Mainly used in the oxygen supply system of professional centers to provide oxygen supply for professional units and oxygen inhalation for patients with hypoxia 5、Exhaust pressure of safety valve is 0.17MPa±0.05MPa and the flow range of 1~10L/min or 1~15L/min. Item Type: Oxygen Inhaler Flow Range: 1~10L/min, 1~15L/min Input and Output: 0. 4MPa~0.5MPa Exhaust Pressure of Safety Valve: 0.17MPa±0.05MPa How to use: 1. When using the inhaler, fill the inhaler bottle with distilled water first. It is forbidden to replace it with physiological saline. The water level in the inhaler bottle is between the upper and lower water levels. Tighten the inhaler bottle. 2. Before inserting the inhaler into the oxygen supply terminal socket, turn off the flow adjustment switch, and then insert the quick plug into the oxygen supply terminal socket hole. When you hear a "click" sound and see the oxygen supply terminal socket locking sleeve automatically slides , It means that the quick plug and the oxygen supply terminal socket have been connected and locked 3. Before supplying oxygen, insert the oxygen inhalation tube (purchased separately) into the oxygen supply connector, and then turn the flow adjustment switch counterclockwise to turn on the air source to make the float rise slowly (the scale line aligned with the center of the float is the flow reading, unit Is liters/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 Article 1 of this item. Screw on the body of the inhaler and continue oxygen supply. 5. When the inhaler is out of use, the air source of the inhaler should be turned off; if it needs to be removed, hold the inhaler with one hand and unlock it with the other hand and then remove it (the unlocking method of the different oxygen supply terminal sockets is explained by the engineering installation unit ). Then pour out the water in the bottle for cleaning and disinfection, and store it in a non-corrosive gas and well-ventilated room. 1 x Oxygen Inhaler 1 x User Manual
