Disposable bud type double nasal plug for nasal ventilation for infants

Abstract

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.

Description

technical field [0001] The invention relates to a disposable bud-type double nasal plug suitable for oxygen inhalation through a nasal catheter for infants, continuous positive airway pressure ventilation through the nose or mechanical ventilation through the nose. Background technique [0002] Many newborns, especially premature infants, require respiratory support after birth. The popularization and use of mechanical ventilation has greatly improved the success rate of neonatal treatment. However, the side effects and long-term prognosis of mechanical ventilation have been paid more and more attention by industry experts. For example, intraventricular hemorrhage, pneumothorax, bronchopulmonary dysplasia, ventilator-associated pneumonia, necrotizing enterocolitis, etc., seriously affect the prognosis and increase neonatal mortality and disability rates. In recent years, non-invasive ventilation modes such as nasal continuous positive airway pressure (nCPAP) are being wide...

AI Technical Summary

Problems solved by technology

In addition, the existing nasal prongs that can provide nCPAP have defects such as inconvenient operation, easy to fall off, air leakage around the nose, and easy damage to the nasal vestibule, which brings great inconvenience to medical staff and requires frequent inspection and adjustment.
