NASAL INTERFACE FOR RESPIRATORY THERAPY MACHINE OF WARMED AND HUMIDIFIED HIGH FLOW RATE OXYGEN METHOD, WHICH MAINTAINS POSITIVE END EXPIRATORY PRESSURE AT PREDETERMINED LEVEL

摘要

The present invention relates to a nasal interface for an respiratory therapy machine in an interface for an artificial respirator. The nasal interface for a respiratory therapy machine of a warmed and humidified high flow rate oxygen method, which maintains positive end expiratory pressure at predetermined level and is characterized by comprising a housing, a pair of outlet tubes, and a pair of induction tubes. The housing has a ventilation space which has a through-hole to be connected to the outside at one side thereof and enables an exchange of inside air and outside air. The housing has an inhalation channel which is separated from the ventilation space by a partition wall and is connected to an oxygen supplier by being connected to the outside at one side. The pair of outlet tubes are separately formed under the housing corresponding to the interval between nasal apertures, protrudes considering the depth of nasal apertures, and are connected to the ventilation space (110). The pair of induction tubes protrudes to the openings of the pair of outlet tubes to supply air which flows into the inhalation channel to the pair of outlet tubes without direct sharing of the ventilation space by being integrated to the partition wall between the inhalation channel and the pair of outlet tubes. The pair of induction tubes enables the opening of the outlet tubes to be open without blocking by making the outer diameter of the cross section of the induction tubes smaller than the inner diameter of the outlet tubes.;COPYRIGHT KIPO 2014
