The aromatic scent emitted by the drugs in the sachet can stimulate the nasal mucosa and make the antibodies on the nasal mucosa—secretory immunoglobulins. The content of A (SIgA) is increased, SIgA has a strong ability to kill the virus, and the SIgA content of the child's nasal mucosa is low, so it is most suitable for hanging.

The oxygen raw material for medical oxygen production mechanism is air. The air is filtered (to remove oil, dust, moisture and solid impurities in the air) and then enters the compressor for compression. The compressed high-pressure air is cooled and then enters the adsorption tower for adsorption and separation. The tower is equipped with molecular sieves, and the nitrogen and carbon dioxide in it will be adsorbed by the molecular sieves. The gas flowing out of the adsorption tower is oxygen with relatively high purity, which can be used as medical oxygen. The separated part of the oxygen enters the gas storage tank through the one-way valve, and is decompressed by the pressure reducing valve, and then flows out through the flow meter and humidification bottle for users to use; the other part of the oxygen is backflushed to clean the adsorber in the desorption state, and desorb The nitrogen is discharged through the muffler High dual-flow medical oxygen concentrator,CE certification 93% concentration oxygen concentrator,portable oxygen concentrator Suzhou Xuanweicheng Biotechnology Co., Ltd , https://www.xwc-medical.com
