Where does the oxygen bag inflate?

There is no special inflation point, because the management of oxygen is also strict, and it is more troublesome to go to a big hospital. You can go to the outpatient department of a small hospital to discuss the payment of inflation. The use time of oxygen bag is very short, which is inconvenient, and even if it is not used for a long time, it will leak. You can consider buying a household oxygen generator with a price of more than 1 1,000 yuan, without worrying about inflation, once and for all.
