多功能氧气面罩
摘要：
本发明公开了一种多功能氧气面罩，其总体上包括面罩主体和气体递送转接器。面罩主体形成内腔，内腔被配置成覆盖患者的口鼻。鼻腔室形成于面罩主体的上部中，鼻腔室包括上部、下部和邻近鼻腔室下部的气体递送转接器孔口。穿过面罩主体的下部并且邻近面罩主体的下部形成的接近孔口。接近孔口被配置成允许接近患者的口部。气体递送转接器具有大体上管状结构并且包括第一端和相对的第二端，气体递送转接器的第一端联接到气体递送转接器孔口。氧气供应端口从气体递送转接器径向向外延伸并且邻近气体递送转接器的第一端。氧气供应端口还包括外部入口部分、定位于气体递送转接器的体积空间内的出口部分以及邻近出口部分的转向器构件。转向器构件被配置成将流动朝向气体递送转接器的第一端导向。定量吸入器端口从气体递送转接器在径向向外延伸。另外，气体递送转接器包括定量吸入器端口和雾化器端口。
摘要（英）：

A multi-function oxygen mask is disclosed which generally comprises a mask body and a gas delivery adapter. The mask body forms an internal cavity configured to cover a nose and mouth of a patient. A nasal chamber is formed in the upper portion of the mask body, the nasal chamber includes an upper portion, a lower portion and a gas delivery adapter aperture adjacent the lower portion of the nasal chamber. An access aperture is formed through and adjacent to the lower portion of the mask body. The access aperture is configured to permit access to the mouth of a patient. The gas delivery adapter has a general tubular structure and includes a first end and opposing second end, the first end of the gas delivery adapter is coupled to the gas delivery adapter aperture. An oxygen supply port radially extends outward from the gas delivery adapter and adjacent to the first end of the gas delivery adapter. The oxygen supply port further includes an external inlet portion, an outlet portion positioned within a volumetric space of the gas delivery adapter and a diverter member adjacent to the outlet portion. The diverter member is configured to direct a flow towards the first end of the gas delivery adapter. A meter-dose inhaler port radially extends outward from the gas delivery adapter. Finally, the gas delivery adapter includes a meter-dose inhaler port and a nebulizer port.
