Abstract
A rearwardly and downwardly opening mask shell is provided for positioning about and over the nose and mouth face areas of a patient in a manner such that the mask shell seals rearwardly against the face of the patient and opens downwardly from the mouth area of the patient. Oxygen inlet means opens inwardly through opposite side portions of the mask shell aligned with the nostril area of the user, and therefore closely adjacent the mouth of the user, and flexible oxygen delivery tubes have discharge ends operatively connected with the oxygen inlet means and the tubes include opposite end portions for communication with an oxygen supply line and which are joined together through the utilization of a soft material connecting strip frictionally adjustable along the tubes such that the connecting strip may pass behind the neck of the user and the tubes may be used to retain the mask shell in position on the face of the user, the mask shell including an upper arched portion constructed of soft material for passing over the nose bridge area of the user and having malleable strip supported therefrom, which strip may be shaped for frictionally gripping the nose bridge area of the patient.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
