(19) As shown in FIGS. 1 through 17, embodiments of the present stable airway management device 10 include a base 15, a pair of support arms 20 maintained within the base 15, a pair of thrust arms 30, each of which is movably secured to a respective support arm 20 and a pair of jaw discs 60, each of which is secured to a respective thrust arm 30. In various embodiments, the base of each thrust arm 30 connects to a respective support arm 20 via a separate thrust arm nose 50. Embodiments of the jaw discs 60 include a substantially elliptical shaped contact surface 62 that provides distributed support along the individual's jaw line when in use. It will be appreciated that pads can be provided on top of and/or around the jaw discs 60 to provide a cushion for the patient during use. Such pads may be made of Styrofoam™ or similar material, for example.

(20) According to various embodiments, such as shown in FIGS. 1 through 3, for example, the base 15 includes a rim 70 useable as a head rest surface for a patient, a platform 80 useable as a neck rest surface for a patient and a back wall 90 which may engage a patient's shoulders during use. The base 15 can further be formed with shoulders 16, each of which has a support arm opening 17 and a latch opening 18.

(21) In various embodiments, each support arm 20 is movably secured to the base 15. For example, as shown in FIGS. 4 through 7, each support arm 20 can be formed with a body 21, a head 22 and a head clip 23. The body 21 can be formed with a front wall 24 and an exposed wall spine 25, wherein the front wall 24 is formed with a series of ridges 26 for interacting with a support arm latch 40 as described elsewhere herein. The head 22 can be formed with an outer wall 27 and an inner wall 28 defining a head opening 29 for receiving a thrust arm 30 as described elsewhere herein. In various embodiments, the body 21, head 22 and head clip 23 are integrally formed as a monolithic unit. The body 21 of the support arm 20 can be positioned through the support arm opening 17 in the base 15 and the support arm latch 40 can further be positioned in the latch opening 18 of the base 15. The head clip 23 can be employed to pull or push the support arm 20 as needed during installation and use.

(22) In various embodiments such as shown in FIGS. 8 and 9, for example, each support arm latch 40 is provided with an outer segment 42 formed with grip ridges 43 on a top side 41 thereof. Each support arm latch 40 can further be provided with an inner lip 44 for engaging the ridges 26 of the support arm(s) 20 as well as latch nodes 45 formed with a gap 46 therebetween for engaging a stem (not shown) on the base 15 to allow the support arm latch 40 to pivotally move about the stem. Each support arm latch 40 can further be provided with legs 47 and a prong 48 extending from each leg 47, wherein the prongs 48 are insertable into receiving areas (not shown) within the base 15 in order to retain the support arm latches 40 therein. During operation, a user can depress the support arm latch 40 such as by pressing a thumb or finger on the grip ridges 43 in order to promote contact between the inner lip 44 of the support arm latch 40 and a ridge 26 on the support arm 20, thereby pushing the support arm 20 upward in incremental distances until the desired extension of the support arm 20 from the base 15 is obtained. Alternatively, the support arm latch 40 can be depressed so as to release any resistance provided by inner lip 44 on a support arm 20, and when the support arm 20 is moved to its desired location, the support arm latch 40 is released so as to permit the inner lip 44 to engage a desired one of the ridges 26 on a support arm. Each support arm latch 40 is thus in communication with a respective support arm 20 and permits adjustment of the extension of a respective support arm 20 from a respective shoulder 16 of the base 15.

(23) As shown in FIGS. 10 through 12, each thrust arm 30 is formed with a main body 31 and an arm extension 32 that extends from an elbow portion 33 at an angle to the axis of the main body 31. A thrust arm knob 34 extends outwardly from the arm extension 32. The main body 31 includes an inside face 35, which can be formed with various steps 36 to permit engagement with a thrust arm release 55 for permitting or restricting movement of the main body 31 of the thrust arm 30 within a respective support arm 20 as described herein. Each thrust arm release 55 can be formed with a front leg 110, a back leg 112, a latching body segment 114 and pivot nodes 115. The pivot nodes 115 can be secured within receiving elements (not shown) of the base and permit the thrust arm release 55 to rotate about an axis A as shown in FIG. 12. The front leg 110 can be formed with gripping ledges 116 for providing frictional surfaces for assisting a user when manipulating the thrust arm release 55. The back leg 112 can be formed with a leg extension 118 that can engage the inner surface of a support arm 20 such that, when a user depresses the front leg 110, the leg extension 118 engages the support arm 20 and the legs 110, 112 can flex so as to permit the latching body segment 114 to pivot about axis A and lift latching notches 117 away from the steps 36 of the inside face 35 of the corresponding thrust arm 30. In this way, a user can move the thrust arm 30 within the opening 29 of the support arm 20 and when the thrust arm 30 reaches its desired location, the user can release the thrust arm release 55 so that the latching notches 117 engage steps 36 on the thrust arm 30 and maintain the thrust arm 30 in place.

(24) As shown in FIGS. 13 and 14, each thrust arm nose 50 is formed with slats 122 and slots 120 for facilitating connection to the support arms 20. As shown in FIGS. 15 and 16, each jaw disc 60 can be formed in a somewhat elliptical shape with a top contact surface 62 and a bottom surface 64. A clasp 66 can be formed with slots 68 to permit flexing of the clasp 66, which can be snapped into place on the thrust arm knob 34 of the thrust arm 30 during assembly and can further be rotated about the thrust arm knob 34 due to the spherical thrust arm knob 34 and the rounded clasp 66. It will be appreciated that the size of the jaw disc 60 can limit the rotational movement of the jaw disc 60 to the degree that the bottom surface 64 may contact a thrust arm 30 during movement.

(25) FIG. 17 illustrates an implementation of the stable airway management device 10 according to embodiments of the present disclosure. As shown therein, the patient's head 200 can be positioned such that the neck lies on rim 70 of the base 15 and the head 200 rests on the platform 80 of the base 15. Pressing one of the latches 40 permits the corresponding support arm 20 to be raised or lowered and pressing the front leg 110 of one of the thrust arm release elements 55 permits the corresponding thrust arm 30 to be raised or lowered. By manipulating the support arm(s) 20 and/or thrust arm(s) 30, the jaw discs 60 can be appropriately positioned under the patient's jaw for proper and stable management of the patient's airway. The patient's chin can be lifted and held in place and the patient's head can be tilted and held in place.

(26) As shown in FIG. 18, the platform 80 of the base 15 includes a first side 150 and a second side 160, where one of the jaw discs 60 is secured to the first side 150 of the platform 80 and another of the jaw discs 60 is secured to the second side 160 of the platform 80. The jaw disc 60 on the first side 150 is secured so as to be liftable and lowerable in a first direction along a first plane 130 relative to the platform 80 and further so as to be liftable and lowerable in a second direction K along the first plane 130. The jaw disc on the second side 160 of the platform 80 is liftable and lowerable in a third direction L along a second plane 132 relative to the platform 80 and further so as to be liftable and lowerable in a fourth direction M along the second plane 132.

(27) As further shown in FIG. 18, the first plane 130 is not co-planar with the second plane 132, which facilitates the device properly engaging a patient during operation of the device. In various embodiments, the thrust arm extension 32 of the thrust arm 30 on the first side 150 is secured to the jaw disc 60 on the first side 150 and extends in a third plane 134 that is not co-planar with the first 130 or second 132 planes. Further, the thrust arm extension 32 of the thrust arm 30 on the second side 160 is secured to the jaw disc 60 on the second side 160 and extends in a fourth plane 136 that is not co-planar with the first 130 or second 132 planes. This arrangement also facilitates the device properly engaging a patient during operation of the device. As further shown in FIG. 18, the fourth plane 136 is not co-planar with the third plane 134. Through the non-coplanar arrangement, the raising and lowering of the jaw discs 60 permits proper alignment with a patient's head during use and proper spacing to permit removal of the patient's head from the device when not in use.

(28) In various embodiments, all elements of the device as described herein are manufactured from materials (e.g., plastic) other than metal. In this way, the device as described herein will not affect other instrumentation such as magnetic resonance imaging (MRI) devices. The device as described herein can be manufactured via additive manufacturing (i.e., 3D printing) techniques according to various embodiments.

(29) Although the present approach has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the present approach.
