摘要：
An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle. Other embodiments may also include spacer structure configured to reduce dead volume inside a syringe that is coupled to the atomizing nozzle.一種霧化噴嘴,特別用於鼻用治療。較佳實施例包括一兩件式霧化噴嘴,此霧化噴嘴係經建構耦接於具有一注射器之魯爾鎖緊結構。此一霧化噴嘴包括一鼻用止擋器及一桿件。一較佳鼻用止擋器包括一遠側頂端,遠側頂端係依尺寸製作而用於插入一人類小孩之一鼻孔,其具有一近側屏蔽部分係經建構用於阻止一排放孔於鼻孔內造成過度插入。一鼻用止擋器合意地提供一定中心功能,藉此以推動排放孔遠離於一鼻腔壁。一可操作桿件係經建構耦接於止擋器且合意地在一近端具有一單一貫穿結構。一第二可操作桿件係經建構為一鼻用止擋器之一單一部件且亦合意地在一近端具有一單一貫穿結構。某些實施例亦可包括一間隔件結構,此間隔件結構係用以降低霧化噴嘴內之失效容積。其它實施例中亦可包括一間隔件結構,此間隔件結構係用以降低耦接至霧化噴嘴之一注射器內之失效容積。100...第一較佳組件102...注射器104...分配噴嘴106...屏蔽108...遠端
