The notice requires relevant medical device manufacturers to re-examine the product instructions, add warnings and tips such as "it is forbidden to use buoy type oxygen inhaler for oxygen atomization inhalation treatment", "it is forbidden to disassemble buoy type oxygen inhaler by themselves" and "humidification Cup" disinfection method and reasonable use period.

The notice requires all medical institutions within the jurisdiction to carry out clinical use in strict accordance with the approved scope of use of the buoy type oxygen inhaler.
