Embodiment Construction

[0039] The disclosed ventilation masks combine features for delivering oxygen or other gases to a patient with an open mask structure. Despite their open mask construction, ventilation masks use fluid dynamics to deliver high concentrations of oxygen or other gases to the patient. Additionally, ventilation masks may utilize fluid dynamics to measure or sample the patient's exhaled gas.

[0040] The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. It will be apparent, however, to one skilled in the art that the subject technology may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order ...

Abstract

Ventilation masks are described herein. A ventilation mask includes a mask body and a gas manifold. The mask body defines a patient cavity and further includes a patient opening in fluid communicationwith the patient cavity; and at least one vent opening formed through the mask body, the at least one vent opening in fluid communication with the patient cavity, wherein the at least one vent opening is disposed generally opposite to the patient opening. The gas manifold is coupled to the mask body. The gas manifold can define a gas channel. The gas manifold can include a plurality of vectored gas ports in fluid communication with the gas channel, wherein the plurality of vectored gas ports are configured to create a curtain effect gas flow within the patient cavity to form a gas curtain within the patient cavity and adjacent to the at least one vent opening.

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application Serial No. 62 / 773,820, filed November 30, 2018, entitled "VENTILATION MASK" and U.S. Provisional Application Serial No. 62, filed July 31, 2018, entitled "VENTILATION MASK." Priority of 62 / 712,933. technical field [0003] The present disclosure relates generally to ventilation masks and, in particular, to ventilation masks having ventilation openings. Background technique [0004] Delivery of supplemental gases, such as air or oxygen, to a patient is a well-known method of treatment for a variety of diseases and conditions. For patients with difficulty breathing, oxygen can be provided from an oxygen supply (eg, pressurized gas cylinders, etc.) through a regulator and a ventilation mask. Ventilation masks may include openings to allow for medical procedures, eating, hygiene and to prevent claustrophobia. [0005] In some applications, it may be difficult to deliv...
