Household Oxygen Concentrator Negative Ion Atomization Oxygen Generator Machine Condition: Item Type: Oxygen Generator Material: High Strength ABS Remote Control Power Supply Mode: 1 x CR2025 Electronic Battery (Not Included) Product Size: Approx. 21.5 x 39.5 x 49cm/8.5 x 15.6 x 19.3in Operating Instructions: Working Environment Temperature: 5℃-40℃ Use Environment Humidity: ≤80% Atmospheric Pressure: 860hPa-1060hPa No strong corrosive gas, no oil, no strong dust and vibration. 1. Operation panel and key functions (1) "Switches" key. Press the "switches" button to turn on or off the oxygen generation function (2) "Timing" button. Press the "Timing" button to adjust the timing time. (3) "Negative ion" key. Press the "negative ion" button to turn on or off the negative ion function. 2. Oxygen production operation (2) Press the "timing" key to adjust the timing time. The time in the center of the display is the oxygen inhalation time set this time, and the time displayed on the top is the cumulative oxygen generation time of the machine. (3) Rotate the flow control valve to increase or decrease the oxygen flow; turn the flow valve counterclockwise to increase the air flow, and turn clockwise to decrease the air flow. (4) Wear a headset-type oxygen tube or nasal-type oxygen tube before inhaling oxygen. (5) After using the machine, press the "switches" key to turn off the oxygen production, and unplug the oxygen tube on the machine. 3. Atomization operation (Only applicable to the atomized version) This machine has an atomization function, the operation steps are as follows: (1) Take out the atomization port cap by rotating, and connect one end of the atomization tube to the atomization port of the oxygen generator; the other end of the atomization tube is connected to the bottom of the atomization cup; (2) Inject liquid medicine into the atomizing cup; (3) Connect the atomizing nozzle or atomizing face shield to the atomizing cup; (4) Put the atomizing nozzle in your mouth or wear a face shield on your face. (5) Press the "switches" button to turn on the atomization function. (6) After the atomization of the liquid medicine is finished, unplug the atomization tube at the atomization port, turn off the machine, and keep it properly. Warning: ▲The expected performance can only be achieved after the machine is turned on for 120 seconds. ▲Oxygen flow rate and oxygen inhalation time, please follow doctor's advice. ▲Patients with hyperthyroidism and other special populations must be used under the guidance of a doctor. ▲Severe patients must be used under the supervision and guidance of a doctor. ▲Patients with severe lung diseases should consult a professional physician for their choice of oxygen intake. ▲This product is a general oxygen production product and cannot be used as a special emergency equipment. ▲If there is a special reactions (such as feeling unfit for the body) or unexpected situation during the use of this product, stop using it and consult relevant professionals or doctors. ▲If this product is equipped with a non-designated humidifier and dosing accessories, its performance may be affected. Note: 1. Oxygen inhalation and atomization cannot be performed at the same time. 2. Please make sure the nozzle, mask and medicine cup are clean before atomizing, or clean it before use. 3. Please follow doctor's advice for the type, dosage, and usage of nebulized medicine, otherwise symptoms may worsen. 4. The maximum capacity of the atomization cup is 8ml, please do not fill the liquid medicine exceeding 8ml. 5. Do not use any medicine in powder form, suspension or high concentration. 6. Keep a certain distance between the atomization component and the eyes, because some medicines atomize and may cause damage to the eyes. 7. It is recommended that each atomization time should not exceed 20 minutes. 8. The atomization components (atomization nozzle or atomization mask) of the parts in contact with the human body can only be used by the same person to prevent cross infection. 9. Do not place or carry the instrument when there is liquid medicine in the atomizing cup. 10. Do not tilt the atomization cup more than 45°, and avoid violent shaking, otherwise, the spilled liquid may make it impossible to inhale the prescribed amount. 11. It is recommended e the atomization components recommended by the manufacturer to prevent affecting its performance.
