Description

A newborn nasal mask

technical field

The utility model relates to the technical field of medical equipment, in particular to a nasal mask for newborns.

Background technique

The nasal mask is an indispensable equipment in the oxygen supply stage. When the patient suffers from anemia, blood loss and other diseases, the red blood cells in the body are insufficient in oxygen carrying capacity, and it is necessary to manually input pure oxygen to the patient to rapidly increase the oxygen content in the body, thereby It ensures the change of the body's internal environment, and the nasal mask can directly introduce pure oxygen into the patient's nasal cavity during the oxygen delivery stage, so that the gas inhaled by the patient will not be mixed with other gases, which is conducive to improving the body's internal environment.

When the traditional neonatal nasal mask is working, it is simply inserted into the patient's nasal cavity through the nasal cannula, and the nasal mask is fixed through the connection between the nasal cannula and the nasal cavity, but this fixation is not reliable, and the nasal mask is in use. During the process, the newborn's mouth needs to be closed to prevent air leakage and the treatment effect is not obvious. However, the newborn has poor self-consciousness and is prone to opening the mouth, which reduces the effect of treatment. At the same time, when the nasal cannula is inserted into the nostril, the machine does not have a scale. Lines, so that the staff can only judge the depth of insertion through experience, it is easy to insert too deep or too shallow, which also results in poor treatment effect.
