A disposable
bud type double nasal plug for nasal ventilation for infants is used for infant
oxygen inhalation through a nasal tube or nasal
continuous positive airway pressure or nasal
mechanical ventilation. The
bud-shaped nasal plug is made of soft and elastic materials. The tube wall of an internal opening of one end of the nasal plug is rolled up and can be firmly inserted into two holes of a vent tube, the other end of the nasal plug is provided with a small opening and turned outside to be arranged on an inner tube in a sleeving mode, and the whole
bud type double nasal plug is inserted into the
nasal cavity. The outer tube wall is thinner than the inner tube wall, the outer tube wall can be closely attached to the
nasal vestibule, air leakage is reduced,
positive airway pressure is guaranteed, the
nasal vestibule can not be injured due to pressure, and the outer tube wall is not prone to disengaging. When the
airway pressure is too large, air leakage is increased accordingly, and the phenomenon of excessive volatility of the
airway pressure is adjusted automatically.
