LOWER FACE OXYGEN MASK

Abstract

A lower face oxygen mask dimensioned and adapted to circumscribe only the mouth of the wearer is provided. The lower face oxygen mask has spaced apart nostril prongs fluidly connecting the nostrils of the wearer with the spaced enclosed by the body of the lower face oxygen mask. The lower face oxygen mask provides an access aperture adjacent with the mouth of the wearer, the access aperture being compatible with standard size bag valve masks and anesthesia circuits. The body of the lower face oxygen mask also provides an access port for inlet and outlet conduits for oxygen and carbon dioxide flow.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] FIG. 1 is a front elevation view of an exemplary embodiment of the present invention; and

[0009] FIG. 2 is a side elevation view of an exemplary embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0010] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0011] Broadly, an embodiment of the present invention provides a lower face oxygen mask dimensioned and adapted to circumscribe only the mouth of the wearer and provide spaced apart nostril prongs fluidly connecting the nostrils of the wearer with the spaced enclosed by the body of the lower face oxygen mask. The lower face oxygen mask provides an access aperture adjacent with the mouth of the wearer, the access aperture being compatible with standard size bag valve masks and anesthesia circuits. The body of the lower face oxygen mask also provides an access port for inlet and outlet conduits for oxygen and carbon dioxide flow.

[0012] Referring now to FIGS. 1 and 2, the present invention may include a lower face oxygen mask 10 dimensioned and adapted to cover just the chin and mouth of the wearer. The lower face oxygen mask 10 has a body 14 defined by a periphery 14a. Though the figures show an oval design of the body 14, other shapes are contemplated so long as they function as disclosed herein. In certain embodiments, the periphery 14a may be an inflatable balloon cuff. The body 14 may be made of transparent material.

[0013] A band 12, most likely elastic, may interconnect two portions of the periphery 14a for securing the lower face oxygen mask 10 to a wearer. At the interface of the band and the periphery 14a may be pull tabs 16 for tightening the lower face oxygen mask 10.

[0014] An access aperture 18 may be provided in the body 14 so as to be in line with the mouth of the wearer. In certain embodiments, the access aperture 18 may be 13 mm in diameter so as to be compatible with bag valve mask (“self-inflating bag”) and anesthesia circuits standard size. In certain embodiments an opening periphery 18a may include corrugated ribs.

[0015] Along an upper portion of the periphery 14a may be two spaced apart conical nasal prongs 22 to establish a seal with various sized nostrils and prevent mask movement towards eyes. The nasal prongs 22 are fluidly coupled to an inner side of the lower face oxygen mask 10.

[0016] An access port 20c may be provided in the body 14. An inlet conduit 20a and an outlet conduit 20b may be fluidly coupled to the access port 20c. The access port 20c may be located slightly inward of the periphery 14a. The inlet and outlet conduits 20a and 20b may be housed in a single tube 20. The inlet conduit 20a is adapted for oxygen delivery and may be five to seven feet in length with a standard sized inverse conical connector used to connect to oxygen flow meters. The outlet conduit 20b being adapted for a carbon dioxide outlet tube.

[0017] All the elements work together to complete purpose of the present invention as a superior mask oxygen delivery device. The present invention can be used in routine cases to provide oxygen to the sedated patient. The lower face oxygen mask 10 can also be used in the endoscopy arena to give access for the endoscopist's upper endoscopy, while adding an increased level of safety with the access aperture 18 being compatible with bag valve masks and anesthesia circuits standard size. Furthermore, the lower face oxygen mask 10 provides more comfort and safety by keeping the mask away from the wearer's eyes.

[0018] A method of using the present invention may include the following. The lower face oxygen mask 10 disclosed above may be provided. During upper endoscopy, patients can desaturate rapidly by using this design the endoscopist can rapidly remove the scope and oxygen delivery device such as a bag valve mask or anesthesia circuit for delivery of positive pressure ventilation and high flow oxygen. Additionally, the present invention can be used as a general oxygen delivery device whenever oxygen delivery is needed.

[0019] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
