Abstract: A multifunction oxygen mask comprises a mask body and a gas delivery adapter. A nasal chamber is formed in the upper portion of the mask body. An access aperture is formed through and adjacent to a lower portion of the mask body. The access aperture permits access to the mouth of a patient. The gas delivery adapter includes a first end coupled to a gas delivery adapter aperture of the mask body. An oxygen supply port radially extends outward from the gas delivery adapter. The oxygen supply port includes an external inlet portion, an outlet portion positioned within 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. The gas delivery adapter includes a nebulizer port.

Abstract: 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 an 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.

Abstract: A mask for delivery of gas, such as oxygen, to a patient and useable in a naso-gastric intubation procedure without disruption of the seal between the mask and the face of the patient. The body of the mask includes a fenestration or opening through which the naso-gastric tube may be inserted. The fenestration is preferably shaped to support the tube in manner which is comfortable for the patient and which eliminates or minimizes the amount of gas lost to the atmosphere outside the mask. In at least some embodiments, the fenestration is closed when a tube is not inserted therethrough so that the mask may be used normally without loss of the gas through the fenestration.
