Patent Application

Concussion, or mild traumatic brain injury (MTBI), is the most common type of traumatic brain injury. Sports-related concussions have increased over the years. This may be relative to the increased physical stature of athletes and the intensity of contact sports over time. Frequently defined as a head injury with a temporary loss of brain function, concussion can cause a variety of physical, cognitive, and emotional symptoms.
The human body generally is built to protect the brain from traumatic injury. Cerebrospinal fluid surrounds the brain beneath the skull. The skull provides the hardened exterior protection, while the cerebrospinal fluid provides a hydraulic “cushion” that protects the brain from light trauma. However, severe impacts or forces associated with rapid acceleration and deceleration may not be absorbed by this cushion. As they are understood, however, concussions are likely caused by impact forces, in which the head strikes or is struck by an object. In other instances, concussion may be caused by impulsive forces, in which the head moves without itself being subject to blunt trauma, such as in the case of severe whiplash.
Concussive forces may engage an individual's head in a manner that causes linear, rotational, or angular movement of the brain. In rotational movement, the head turns around its center of gravity, and in angular movement it turns on an axis not through its center of gravity. Concussions and their proximate causation remain the center of study and debate. However, it is generally accepted that the threshold amount of blunt force for concussion is approximately 70-75 g. Impacts to the individual's head of this magnitude and greater are thought to adversely affect the midbrain and diencephalon. The forces from the injury are believed to disrupt the normal cellular activities in the reticular activating system located in these areas. Such disruption may produce loss of consciousness, which often occurs in concussion injuries.
The prior art has produced a wide array of protective equipment, such as helmets, mouth guards, and other headgear in an attempt to reduce the number of sports-related concussions. In particular, mouth guards are believed to help prevent concussions as well as protect the user's teeth from damage. Traditionally, mouth guards have been formed of plastic or rubber and engage a user's upper teeth to keep the guard in position. Some mouth guards include moldable materials whereby a user can custom fit the mouth guard to their teeth for a more comfortable fit. In the past, a mouth guard that kept the user's teeth from contacting each other was considered sufficient. Regarding concussions, traditional mouth guards have generally relied on the resiliency of the plastic or rubber that they are formed from to cushion an impact transferred through a user's jaw. Thus, there exists a need to innovate to innovate with respect to mouth guard design in order to better help prevent concussion injuries.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary, and the foregoing Background, are not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.
Described herein is a mouth guard that comprises an arcuate body member positionable between the upper and lower teeth of a user for protecting the user's teeth and helping to prevent concussions. The body member includes an incisor portion for confronting the incisors of the user and a pair of molar portions for confronting the molars of the user. Each said molar portion includes a hollow region. The hollow region may extend through its respective molar portion. Alternatively, the hollow region is contained within the body member and may also be air tight. The hollow region could also be a blind cavity. A resilient member, such as a spring or foam material, may be disposed within the hollow region.
A bladder may be disposed in the hollow region, such as an air bladder or a bladder containing gel. A resilient member, such as a spring or foam material, may be disposed within the bladder. The bladder may be formed of a translucent or transparent material.
The mouth guard may also be described as including an arcuate body member positionable between the maxilla and mandible of a user. The mouth guard includes a pair of walls extending from the body member to form a tray adapted to receive the maxillary teeth of the user. The tray includes an incisor region and a pair of molar regions. At least one hollow region is formed in the body member below the tray. The hollow region may be formed below the incisor region, below the molar regions or both.
These and other aspects of the mouth guard will be apparent after consideration of the Detailed Description and Figures herein. It is to be understood, however, that the scope of the invention shall be determined by the claims as. issued and not by whether the given subject matter addresses any or all issues noted in the Background or includes any features or aspects recited in this Summary.
Non-limiting and non-exhaustive embodiments of the present invention, including the preferred embodiment, are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified.
Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense.

The mouth guards described herein may be formed of a suitable rubber or plastic materials as are known in the art. For example and without limitation, the mouth guard may be formed from thermoplastic elastomer (TPE) or ethylene vinyl acetate (EVA) or a combination thereof. The mouth guard may be formed by any suitable manufacturing process, such as for example injection molding, insert molding, welding, gluing, and the like. In addition, the mouth guards described herein may be decorated with in mold labeling and in mold decorating techniques as are known in the art.
Although the technology and methods of using and/or applying the same have been described in language that is specific to certain structures, materials, and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures, materials, and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended. Unless otherwise indicated, all numbers or expressions, such as those expressing dimensions, physical characteristics, etc. used in the specification (other than the claims) are understood as modified in all instances by the term “approximately.” At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the claims, each numerical parameter recited in the specification or claims which is modified by the term “approximately” should at least be construed in light of the number of recited significant digits and by applying ordinary rounding techniques. Moreover, all ranges disclosed herein are to be understood to encompass and provide support for claims that recite any and all subranges or any and all individual values subsumed therein. For example, a stated range of 1 to 10 should be considered to include and provide support for claims that recite any and all subranges or individual values that are between and/or inclusive of the minimum value of 1 and the maximum value of 10; that is, all subranges beginning with a minimum value of 1 or more and ending with a maximum value of 10 or less (e.g., 5.5 to 10, 2.34 to 3.56, and so forth) or any values from 1 to 10 (e.g., 3, 5.8, 9.9994, and so forth).
