Airway humidifier for the respiratory tract

摘要: According to the present invention, an airway humidifier for directly humidifying air flow requirement of a respiratory tract during inspiration phase breathing cycle is provided, which comprises nest relatively large bore, thin wall transmitting elongated hollow fibers terminating at output end that adapted communicate merged through tube tract, water chamber surrounding said and having sufficient rigidity resist collapse when subjected negative operational pressure, source heated about 105° F. (40° C.) pump connected maintain filled with under internal diameter order 0.050 inch, being in number length enable peak rate proceed characteristic pressure drop less than 5 centimeters water, walls wettable surface conditions permeable vapor impermeable liquid aggregate wetted area humidify whereby pulsing into can be humidified by compact, closely-located unit.
