Description

An adjustable neonatal resuscitation bag

technical field

The utility model relates to the field of medical appliances, in particular to an adjustable neonatal resuscitation bag.

Background technique

In severe neonatal asphyxia, correcting hypoxia and acidosis is the key to resuscitation, and pressurized oxygen is an important part. At present, manual airbags are mainly used for pressurized oxygen in clinical practice.
