Oxygen masks
The present disclosure relates to an oxygen mask comprising: a mask body defining a cavity configured to be positioned over the mouth and nose of a patient, an oxygen port formed on the upper half of the mask body, an annular aperture formed on the mask body, and at least one vent port formed on the mask body, wherein each vent port is formed on the bottom half of the mask body in a manner that patient's exhaled gases are directed towards the vent port.
1. An oxygen mask comprising:
a mask body defining a cavity configured to be positioned over the mouth and nose of a patient, wherein the mask body is formed to define a reservoir for storing oxygen during expiration and the size of the reservoir is approximately 20 cc to 100 cc, and wherein the mask body is configured to be placed over a nasal cannula on the patient's face,
an oxygen port formed on the upper half of the mask body,
an oxygen storage tube directly coupled to a vent port at the bottom half of the mask body,
an annular aperture formed on the mask body in a manner that the annular aperture provides mouth access of the patient, and
a second vent port formed at a distal end of the oxygen storage tube, wherein the second vent port is formed to create an additional reservoir between the vent port at the bottom of the mask body and the second vent port.
2. The oxygen mask of claim 1 , wherein the oxygen storage tube is adjustable to increase or decrease the volume of the oxygen storage tube.
3. The oxygen mask of claim 1 , wherein the oxygen storage tube is configured to couple to a filter or continuous positive airway pressure machine.
4. The oxygen mask of claim 1 , wherein the oxygen mask is configured to store about 75 cc of oxygen when the oxygen mask is worn.
5. The oxygen mask of claim 1 , wherein the oxygen storage tube is attached to the vent port of the mask body within one inch from the bottom of the mask body.
6. The oxygen mask of claim 1 , wherein the annular aperture is formed near a central area of the mask body.
