[0101] Referring now to the drawings, one or more oral airways in accordance with one or more preferred embodiments of the invention are next described. The following description of such oral airways is merely exemplary in nature and is in no way intended to limit the invention, its applications, or uses.

[0102] Turning now to FIGS. 1-4, commercially available oral airways are illustrated. In particular, FIGS. 1-2 illustrate the Ovassapian oral airway; FIG. 3 illustrates the Williams oral airway; and FIG. 4 illustrates the Berman oral airway, all of which are commercially available and are described in detail in the background of the invention section above.

[0103] In contrast, oral airways in accordance with preferred embodiments of the invention are illustrated in FIGS. 5-10. In particular, FIGS. 5-7 illustrate an oral airway 100 in accordance with a first preferred embodiment of the invention; FIG. 8 illustrates an oral airway 200 in accordance with a second preferred embodiment of the present invention; FIGS. 9 and 10 illustrate an oral airway 300 in accordance with a third preferred embodiment of the invention; and FIGS. 11-35 illustrate an oral airway 400, or components thereof, in accordance with a fourth embodiment of the invention.

[0104] As shown in FIGS. 5 and 6, the oral airway 100 includes a first component 102 and a second component 104 that are removably coupled together to form the oral airway 100. A dashed line 106 is included in FIG. 5 to demarcate a preferred juncture between the first component 102 and the second component 104. The demarcation line 106 also extends in similar fashion about the other side of the oral airway 100. The first component 102 extends over the second component 104 and forms the top of the oral airway 100, with the second component 104 forming the bottom of the oral airway 100. When coupled together, the first component 102 and the second component 104 define a conduit 108 having a first opening 110 and a second opening 112 through which a fiber-optic scope and an endotracheal tube may be extended for intubation of the trachea.

[0105] The first component 102 and the second component 104 are shown decoupled from one another in FIG. 6. When so disengaged, each of the components 102,104 may be independently removed from the mouth of a patient without disrupting the proper placement of an endotracheal tube in the trachea of a patient.

[0106] When coupled together, the first component 102 and the second component 104 preferably are forcibly retained in this condition until some minimum amount of force is applied to separate the components 102,104. In the oral airway 100, detents 114 are utilized to retain the coupling between the two components 102,104. In this regard, the detents are formed on elastic, spring-like lever arms 116 that extend from and form part of the second component 104 and that are received within corresponding slots 118 formed in sidewalls of the first component 102. The detents 114 are received and retained by corresponding depressions 120 formed in the slots 118 of the first component 102.

[0107] The oral airway 200 of FIG. 8 includes a first component 202 and a second component 204 that are removably coupled together to form the oral airway 200, and is generally similar in design to the oral airway 100 of FIGS. 5-7. The differences between the oral airway 100 and the oral airway 200 relate to the mechanism that is utilized to retain the first and second components 102,104 and 202,204 in their respective coupled disposition. In this regard, while the oral airway 100 of FIGS. 5-7 utilizes an interlocking mechanical structure, including elastic elements, to maintain the components 102,104 in their coupled disposition, the oral airway 200 of FIG. 8 utilizes magnetism to maintain the coupling. Specifically, sidewalls of the first component 202 include magnetized elements 214 and sidewalls of the second component 204 of the oral airway 200 include magnetized elements 216 that respectively attract each other when the two components 102,104 are coupled together.

[0108] In various alternative designs of the preferred embodiments, the juncture of the first component and the second component could extend along the top and bottom of the oral airway such that the oral airway splits into two halves wherein, for example, each half is a mirror image of the other. One such example of such an arrangement is shown in FIGS. 9 and 10, wherein an oral airway 300 includes a first component 302 and a second component 304 that are removably coupled together to form the oral airway 300. This oral airway 300 is generally similar in design to the oral airway 100 of FIGS. 5-7 or the oral airway 200 of FIG. 8, except that the two components 302,304 are joined along a vertical juncture, demarcated by a dashed line 306 as shown in FIGS. 9 and 10, rather than by a horizontal juncture such as, for example, the juncture demarcated by dashed line 106 in FIG. 5.

[0109] Other configurations are within the scope of the invention, with the common feature being that the oral airway separates into two independent pieces such that the oral airway may be removed directly away from the sides an endotracheal tube without displacement of the endotracheal tube. In other words, when coupled, the two components preferably completely encompass or encircle an endotracheal tube extended through the conduit of the oral airway and, when decoupled, the two components preferably do not completely encompass or encircle an endotracheal tube such that each component may be independently removed away from the endotracheal tube.

[0110] Yet another oral airway 400and components thereofin accordance with a preferred embodiment of the invention collectively are illustrated in FIGS. 11-35. In particular, FIGS. 11, 15, 18, 21, 24, 27, 30, and 33 illustrate various views of the first component 402 and second component 404 removably coupled together to form the oral airway 400. FIGS. 13, 16, 19, 22, 25, 28, and 31 illustrate various corresponding views of the first component 402, and FIGS. 14, 17, 20, 23, 26, 29 and 32 likewise illustrate various corresponding views of the second component 404. FIG. 12 illustrates an exploded view of the first component 402 and second component 404 arrived at by decoupling and sliding of the second component 404 in the direction of arrow A relative to the first component 402. FIGS. 34 and 35 illustrate partial views of the oral airway 400 focusing on corresponding elements of the latch mechanism of the oral airway 400.

[0111] When the first component 402 and second component 404 are removably coupled together to form the oral airway 400, the first component 402 extends over the second component 404 and forms the top of the oral airway 400, with the second component 404 forming the bottom of the oral airway 400. As such, the first component 402 sometimes may be referred to herein as the superior component and the second component 404 sometimes may be referred to herein as the superior component 404.

[0112] Furthermore, when coupled together, the first component 402 and the second component 404 collectively define a conduit 408 (FIG. 21) having a first opening 410 (FIG. 11) and a second opening 412 (FIG. 18) through which, for example, a fiber-optic scope and/or an endotracheal tube may be extended for intubation of the trachea. Preferably, the internal dimension of the conduit is maximized in order to accommodate sizes of endotracheal tubes that are larger than what conventional oral airways will accommodate. Preferred dimensions for a size#9 (90 mm) oral airway are identified in the drawings and, in particular, FIGS. 21, 22, 23, and 30. The internal diameter in this illustrated embodiment is approximately 0.9 inches at the first and second portions of the first component 402 as shown in FIG. 30.

[0113] The first component 402 and the second component 404 also are forcibly retained in this condition until some minimum amount of force is applied to separate the components 402,404. Specifically, an interlocking mechanical structure is utilized in the oral airway 400 to retain the coupling between the two components 402,404. The first component 402 includes a first elongate tongue 452 (FIG. 19) and a second elongate tongue 454 (FIG. 19) extending in generally parallel relation. The second component 404 includes a first elongate groove 456 (FIG. 17) and a second elongate groove 458 (FIG. 17) extending in generally parallel relation. When the first and second components 402,404 are removably coupled together, the first and second tongues 452,454 extend, respectively, within the first and second grooves 456,458. Specifically, each tongue 452,454 includes a leading end 453 (FIG. 19) and a trailing end 455 (FIG. 19); each groove 456,458 includes an opening 460 (FIG. 17) at a forward end 457 (FIG. 14) for receiving the leading end 453 of a respective tongue 452,454 therethrough; and, when the first and second components 402,404 are removably coupled together, the elongate tongues 452,454 are received respectively within the elongate grooves 456,458.

[0114] Each tongue 452,454 further includes a raised bump or protuberance 462 (FIG. 35) proximate the leading end 453; each groove 456,458 further includes an indentation or recess 464 (FIG. 34) located proximate the rear end 459; and, when the first and second components 402,404 are removably coupled together, each protuberance 462 is received within a recess 464 for latching of the first and second components 402,404 in physical engagement with one another.

[0115] Each tongue 452,454 includes a cross-sectional profile that closely corresponds to a cross-sectional profile of a groove 456,458 for close fitting of the tongue 452,454 within the groove 456,458 without undesired play.

[0116] The oral airway 400 also includes a mouth guard for abutting an exterior area of the mouth of a patient during endotracheal intubation and preventing the oral airway 400 from overextending into the mouth of the patient. In particular, the first component 402 forms a first mouth guard portion 466 (FIG. 12) and the second component 404 forms a second mouth guard portion 468 (FIG. 12), with the first mouth guard portion 466 and the second mouth guard portion 468 defining the mouth guard itself. The first component 402 and the second component 404 also preferably define a chamfer 470 (FIG. 21) between the conduit 408 and an exterior surface of the mouth guard for facilitating the introduction of a fiber-optic scope or an endotracheal tube.

[0117] The first mouth guard portion 466 and the second mouth guard portion 468 each have respective surfaces 472,474 (FIG. 21) that extend in generally coplanar relation for presenting a flush exterior mouth guard surface as seen, for example, in FIG. 18. Furthermore, as perhaps best seen in FIG. 21, the first mouth guard portion 466 extends adjacent opposite lateral sides 476 of the second mouth guard portion 468 thereby bracketing the second mouth guard portion 468. The first mouth guard portion 466 may be characterized as generally M shaped or C shaped, as perhaps best seen in FIG. 22. Moreover, the second mouth guard portion 468 may be characterized as generally U shaped, as perhaps best seen in FIG. 23.

[0118] The second mouth guard portion 468 also includes an area 478 dimensioned for grasping between a finger and thumb of a hand for decoupling of the first and second components 402,404. This area 478 preferably comprises a pull-tab and corresponds to, at least to some extent if not completely, the second mouth guard portion 468.

[0119] With specific regard to the first component 402, the first component 402 includes an anterior portion 480 (FIG. 28) and a posterior elbow portion 482 (FIG. 28). The anterior portion 480 extends generally linearly in a longitudinal direction along a first extent and includes a first curved surface 481 (FIG. 19). The posterior elbow portion 482 extends generally curvilinearly in the longitudinal direction and includes a second curved surface 483 (FIG. 19) that defines a posterior curve 485 (FIG. 28). Furthermore, the second curved surface 483 of the posterior elbow portion 482 and the first curved surface 481 of the anterior portion 480 together define a first, superior guiding surface of the oral airway 400.

[0120] Likewise, with specific regard to the second component 404, the second component 404 also has a first portion 486 (FIG. 29) and a second portion 488 (FIG. 29). The first portion 486 extends generally linearly in the longitudinal direction approximately the first extent and includes a first curved surface 487 (FIG. 17) located in opposing relation to the first curved surface 481 of the anterior portion 480 of the first component 402. The second portion 488 includes a second curved surface 489 (FIG. 17) located in opposing relation to the second curved surface 483 of the posterior elbow portion 482 of the first component 402. The second portion 488 of the second component 404 also includes tapering side edges 490 (FIG. 29). The second curved surface 489 of the second portion 488 of the second component 404 and the first curved surface 487 of the first portion 486 of the second component 404 together define a second, inferior guiding surface of the oral airway 400.

[0121] As will be appreciated from the drawings, the superior guiding surface and the inferior guiding surface together define and encompass an interior passage (i.e., conduit 408) through the oral airway 400. This interior passage preferably is dimensioned to direct a fiber-optic scope or an endotracheal tube extending through the interior passage for tracheal intubation. As shown by the cross-sectional view of FIG. 33, the interior passage is generally oval in cross-sectional profile as indicated at 491 and, specifically, is generally circular in cross-sectional profile.

[0122] With continuing reference to FIG. 33, the first and second components 402,404 include a continuous, uninterrupted curved outer exterior surface 492 (FIG. 27) that circumferentially surrounds the interior passage, and this exterior surface 492 is generally oval in cross-sectional profile as indicated at 493 in FIG. 33.

[0123] The first component 402 of the oral airway 400 also includes a first generally planar member 495 (FIG. 24) that protracts in opposite lateral directions from the exterior surface 492 of the anterior portion 480 of the first component 402. Likewise, the second component 404 includes a second generally planar member 497 (FIG. 26) that protracts in opposite lateral directions from the exterior surface 492 of the first portion 486 of the second component 404. The first generally planar member 495 and the second generally planar member 497 extend in spaced parallel relation to one another and are configured to splint the teeth of the mouth of a patient and provide stability against rotation or wobbling of the oral airway 400 during endotracheal intubation. The second generally planar member 497 also includes a flat lingual surface 496 (FIG. 18) that is configured to forwardly depress the tongue of a patient during endotracheal intubation.

[0124] In use of any of the foregoing oral airways, a method of tracheal intubation includes the steps of extending a fiber-optic scope or an endotracheal tube through a conduit defined by first and second components of an oral airway, wherein the first and second components are removably coupled together to define the conduit; decoupling the first and second components after an endotracheal tube has been extended through the conduit for tracheal intubation such that the first and second components are physically separated from one another; removing the first component from the patient's mouth without disrupting the endotracheal tube; and removing the second component from the patient's mouth without disrupting the endotracheal tube. The step of decoupling the first and second components includes sliding one of the components relative to the other of the components. The step of decoupling the first and second components comprises further applying a sufficient amount of force to overcome a latch that serves to retain the first and second components together in fixed disposition. When decoupled, each of the components may be independently removed from the mouth of a patient without disrupting the proper placement of an endotracheal tube in the trachea of the patient. With reference to the oral airway 400, the inferior component 404 preferably is removed and then the superior component 402 is removed.

[0125] Returning now to consideration of all of the illustrated embodiments of the drawings, preferably the walls of the components 102,104 of oral airway 100, the walls of the components 202,204 of oral airway 200, the walls of the components 302,304 of oral airway 300, and the walls of the components 402,404 of oral airway 400 are constructed from medical grade low density polyethylene and have sufficient rigidityor are reinforcedso as to prevent collapse when the oral airway is bitten down upon by a patient. The oral airways also preferably are latex free.

[0126] Oral airways in accordance with preferred embodiments of the invention may be produced in a variety of sizes ranging from neonatal to large adult sizes. As such, the oral airways preferably are color coded so as to indicate size upon quick visual observation.

[0127] Additionally and/or alternatively, an oral airway in accordance with the present invention may be adapted, configured, or manufactured to provide a desirable smell and/or taste. For example, a flavoring material may be applied during the manufacture of the oral airway, or may be applied afterwards, that results in a desirable flavor being experienced when the oral airway is utilized in the mouth. The flavor may be, for example, that of a food, a natural flavor, or an artificial flavor including, but not limited to, bubble gum or a fruit, such as an orange. Alternatively, or in addition, a material may be may be applied during the manufacture of the oral airway, or may be applied afterwards, that results in a desirable scent or odor being experienced when the oral airway is utilized. The scent or odor may be that of a food or other pleasant item. In connection with the flavoring and/or scent, the oral airway may include a corresponding color, such as a pink color if the flavoring and/or scent is that of bubble gum.
