However, once installed, piping at gas production facilities and piping at hospitals is used for many years, so condensation can occur in the piping, and contamination can occur when connected to equipment or gas storage containers due to exposure to the atmosphere. There are things to do. However, conventionally, no measures have been taken to remove impurities mixed in the medical gas either in the filling route or in the usage route.

The gas may become contaminated by passing through pipes contaminated with germs, and when the patient inhales it, it may be contaminated with impurities such as fungi and particles. Patients to whom this medical gas is used often have a reduced resistance, but if a patient with such a reduced resistance inhales gas contaminated with impurities, there is a risk of pneumonia. However, in patients taking immunosuppressants, any type of bacteria could cause an infection.
