Humidifier Bottle without Nut
This is nothing but humidifier bottle having threading on the top if the bottle that is to fix the bottle to the FA valve regulator. It is used as a spare part for Oxygen FA valve regulator. It is called as humidifier bottle with threading or humidifier bottle without nut. Oxygen gas is released from FA valve regulator and passes through this humidifier bottle. During the process it humidifies the gas and thus avoids dryness in patient nasal ares and thus avoid itching. Water is poured in the bottle and tightened before releasing the gas.
One can observe the Oxygen bubbles when the gas passes through the humidifier bottle. There will a rubber washer inside the bottle to avoid the gas leakage. So when filling the water one has to maintain the washer without falling from the bottle. There will marking of maximum and minimum water level on the bottle. Water has to be maintained at minimum level when the flow of oxygen is more than 3 ltrs per minute. This is to avoid leakage of Oxygen gas into oxyset. At lower Oxygen flow rates one can pour up to maximum level.
It is always recommended to pour mineral water, otherwise scaling is observed after usage of some number of days. Oxy set is attached from the outlet opening of the bottle and gas flows through the oxy set to the patient. FA valve regulator shall be closed while releasing the gas from cylinder. As the pressure comes from the cylinder is at high pressure one has to operate carefully and release the nob of FA valve slowly to give oxygen to patient. So the attendees or nursing staff shall be trained before giving the gas to the patients. This is mainly used by hospitals, nursing homes, home care patients and clinics and diagnostic centers.
