A person with unilateral facial paralysis (typically Bell's Palsy) may face difficulty when eating. More specifically, it may be difficult to avoid biting the cheek and lip when such an individual chews food. It may also be difficult to retain food and liquids within the mouth when such an individual lacks the necessary muscle tone or the ability to control muscles on one side of the face while chewing food, which often occurs when an individual has unilateral facial paralysis. The present disclosure provides a device that helps to retain food and liquids within the mouth. The device also may act as a cheek and lip guard to prevent biting the cheek and lip while an individual is chewing food.

The mouth plate 12 is also sized and configured to span a space or gap 38 between top and bottom teeth of the adjacent teeth 26 when the jaw 41 is opened to retain food items within the oral cavity 18. The mouth plate 12 is also sized and configured to not span an upper end 40 and a lower end 42 of the vestibule 22 when the jaw 41 is closed. The space or gap 38 between the top and bottom teeth of the adjacent teeth 26 is also closed when the jaw 41 is closed. The mouth plate 12 may be shaped and sized to fit into the vestibule 22 when the jaw 41 is both opened and closed and to span the gap 38 between top and bottom teeth of the adjacent teeth 26 when the jaw 41 is opened in order to retain food items within the oral cavity 18. For example (i) the mouth plate 12 may have a width, W1, that is sufficiently thin so that the mouth plate 12 may be disposed within the vestibule 22 between the cheek 24 and the adjacent teeth 26, (ii) may have a height, H1, that is sufficiently tall to span the gap 38 between top and bottom teeth of the adjacent teeth 26 when the jaw 41 is opened, and (iii) may have a top edge 44 and a bottom edge 46 that are substantially parallel so as to not come into contact with the upper end 40 and the lower end 42 of the vestibule 22, respectively, when the jaw 41 is closed. Substantially parallel may refer to any incremental value that is between exactly parallel and 15° from exactly parallel.
The mouth plate 12 may also span an entire half of the teeth 26 from the front teeth (e.g., the front incisors) to the back teeth (e.g., the back molars). Although illustrated along one side of the mouth, the mouth plate 12 may be disposed along either the left or right side of the mouth 20. More specifically, the eating assistance device 10 may be symmetrical along a longitudinal plane or horizontal plane to facilitate ease of use on either side of the mouth 20.
Opposing ends 48 of the mouth plate 12 taper from the top edge 44 and the bottom edge 46. Stated in other terms, the opposing ends 48 of the mouth plate 12 are rounded or have fillets to eliminate sharp corners. An outer peripheral edge 50 of the mouth plate 12 is also rounded or has fillets to eliminate sharp corners. The outer peripheral edge 50 may include the top edge 44, the bottom edge 46, and the opposing ends 48 of the mouth plate 12. The rounded ends and edges of the mouth plate 12 are included for safety purposes. More specifically, by including the rounded ends and edges, any sharp corners or edges that may cause lacerations are eliminated. The rounded ends and edges also help to facilitate inserting and removing the mouth plate 12 from the vestibule 22.

The user handle 14 may more specifically be connected to the mouth plate 12 via the linking arm 16. The linking arm 16 may secure an end 52 of the user handle 14 to one of the ends 48 of the mouth plate 12. The linking arm 16 may also orient the user handle 14 at an angle, θ, relative to the end 48 of the mouth plate 12 that ranges between 135° and 225°. The user handle 14 may also be thicker along a distal end 53 relative to a proximal end 55 that is adjacent to the mouth plate 12 and the linking arm 12. Stated in other terms, the user handle 14 may taper in a direction that extends from the distal end 53 relative to a proximal end 55.
The user handle 14 may also include has a tear-drop shaped cross-section 56 that tapers laterally toward the mouth plate 12. The tear-drop shaped cross-section 56 may more specifically be defined along a section 58 of the user handle 14 that is proximal to the mouth plate 12 and linking arm 16. The tear-drop shaped cross-section 56 provides additional space between the user handle 14 and user's face or cheek along top and bottom sides of the user handle 14 so that a user's finger 59 (e.g., index finger) and thumb 60 may be utilized to pinch the cheek 24 and/or lips 62 (See

The linking arm 16 is substantially flat and is sized such that the opening 54 to the oral cavity 18 or the lips 62 may be closed over the linking arm 16. More specifically, an upper surface 64 and an opposing lower surface 66 of the liking arm 16 may each be substantially flat such that the opening 54 to the oral cavity 18 or the lips 62 may be closed over the linking arm 16. Substantially flat may refer to a flat surface that has no deviations from a perfectly flat plane or has deviations from the perfectly flat plane that are less than a tolerance. For example, the upper surface 64 and the lower surface 66 may have an allowable tolerance of 2 millimeters (mm) or less, 1 mm or less, or 0.5 mm or less, 0.25 mm or less, etc. from corresponding perfectly flat planes.
The linking arm 16 has a cross-sectional shape 68 that tapers in a direction that extends from an end toward a center of the opening 54 to the oral cavity 18 or toward a center of the lips 62 when the mouth plate 12 is disposed within the oral cavity 18 and more specifically when the mouth plate 12 is disposed within the vestibule 22. More specifically, the linking arm 16 (i) may be thinner along an external edge 70 that is positioned toward a center of the opening 54 to the oral cavity 18 (or toward a center of the lips 62) to allow the lips 62 to close or seal over the linking arm 16 to minimize the leakage of food and liquids from the oral cavity and (ii) may be thicker and rounded (or filleted) along an internal edge 72 that that is positioned in a corner of the opening 54 to oral cavity 18 (or a corner of the closed lips 62) for comfort purposes. Please note that the cross-section cut line for
The mouth plate 12, user handle 14, and linking arm 16 have vertical dimensions or heights, H1, H2, and H3 respectively, that extend in a direction from a top to a bottom of the mouth 20 when the mouth plate 12 is disposed within the oral cavity 18 and more specifically when the mouth plate 12 is disposed within the vestibule 22. The height of the linking arm, H3, is smaller than the height of the mouth plate, H1, and the height, H2, of the user handle 14, and is sized such that the opening 54 to the oral cavity 18 or the lips 62 may be closed or sealed over the linking arm 16. The height, H2, of the user handle 14 may also be smaller than the height of the mouth plate, H1.
The linking arm 16 defines an arc 74 that orients the user handle 14 at the angle, θ, relative to the end 48 of the mouth plate 12. The curvature of an inner or internal edge 76 of the linking arm 16, as seen from above, may be greater than the thickness of the cheek 24, so that the user handle 14 will sit near the surface of the face when the eating assistance device 10 is being used. This allows a user's the fingers to both hold onto the user handle 14 and to hold the lips 62 shut against the upper surface 64 and the lower surface 66 of the linking arm 16 along one side of the mouth 20 in order retain food items within the oral cavity 18. Also, curvature of an inner or internal edge 76 of the linking arm 16, as seen from above, may be greater than the thickness of the cheek 24, so that the cheek 24 may comfortably rest within a slot 78 defined by the internal edge 76 of the linking arm 16. The slot 78 is configured to straddle the cheek 24 via the opening 54 to the oral cavity 18 when the mouth plate 12 is disposed within the vestibule 22.
The eating assistance device 10 may be made from any material but is preferably made from a material that will not damage the teeth 26 or soft tissue within the mouth 20. For example, the eating assistance device 10 may be made from a plastic material, such as a thermoplastic, thermoset plastic, or polymer. The material should be sufficiently rigid to maintain the shape of the eating assistance device 10 while being used but should be soft enough so as to not damage the teeth 26 or soft tissue within the mouth 20. However, the material is not limited to plastic materials and the eating assistance device 10 may alternatively be made from any metallic material, including but not limited to stainless steel.
It should be understood that the designations of first, second, third, fourth, etc. for any component, state, or condition described herein may be rearranged in the claims so that they are in chronological order with respect to the claims. Furthermore, it should be understood that elements labelled upper, lower, top, bottom, left, right, etc. may be adjusted if the eating assistance device 10 is utilized on the other side of the mouth 20 than illustrated.
The words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure. As previously described, the features of various embodiments may be combined to form further embodiments that may not be explicitly described or illustrated. While various embodiments could have been described as providing advantages or being preferred over other embodiments or prior art implementations with respect to one or more desired characteristics, those of ordinary skill in the art recognize that one or more features or characteristics may be compromised to achieve desired overall system attributes, which depend on the specific application and implementation. As such, embodiments described as less desirable than other embodiments or prior art implementations with respect to one or more characteristics are not outside the scope of the disclosure and may be desirable for particular applications.
