In the family oxygen therapy, we often need to use the medical molecular sieve oxygen concentrator. What should we pay attention to in the process of daily use?

1. Bottled purified water or distilled water purchased from the supermarket should be used in the humidification bottle. If it is not available, it is not recommended to directly use tap water or mineral water. The amount of water should reach half of the humidification bottle, otherwise the water in the bottle is easy to escape or enter the oxygen suction tube, and the water in the bottle should be replaced in about three days.

2. Regularly clean and replace the inner and outer sets of filter cotton. The filter cotton must be thoroughly dried before it can be replaced into the machine.

3.Keep at least 30cm away from the ground after use.

4. When the oxygen concentrator is started, do not adjust the flowmeter to gear 0 (at least keep it above 1L, usually about 2l-3.5l).

5. Keep upright during transportation and storage. It is strictly prohibited to place horizontally, upside down and wet.

6. During daily use, pay attention to the unique “exhaust sound” of the oxygen concentrator to judge whether the machine operates normally: that is, there will be a “poop” sound every 7 ~ 12 seconds during startup and operation, which is discharging nitrogen.

7. When it is necessary to inflate the oxygen bag, please note that after the oxygen bag is filled, operate in the order of removing the oxygen bag first and then turning off the oxygen concentrator.

8. If the oxygen concentrator is idle for a long time, it will affect the activity of molecular sieve (especially in humid environment). It should be started up for several hours every month for self drying, or wrapped in plastic bags and stored in the original packing box.
