The present invention relates generally to the field of sports equipment for protecting the teeth from injury, that also has a means for delivery of hydration fluids to the mouth.
There are a number of physical activities that require protection of the teeth from impact, such as ice hockey, soccer and football. Participants in these sports most often wear mouth guards to protect their teeth, and also to avoid biting their tongue.
Because these activities demand considerable exertion, the players need to take frequent breaks to drink water. This can be done only when the player is on the bench during a break.
The current standardized mouthpieces/bite valves attached to water bladder tubes are not intended to remain in the user's mouth all the time. They are simple to lose from the user's mouth, distracting, and people usually stop using them while exercising.
In the case of ice hockey, players wear face shields and bulky gloves, and cannot quickly manage their fluid intake. To take a simple drink they need to (i) spit out their mouthguard, (ii) locate their water bottle and take a drink, (iii) take off their glove, (iv) lift up their shield, (v) take the drink, (vi) put the mouthguard back in their mouth with their free hand, (vii) close their shield, and (vii) put their glove back on.
The above sequence of steps cannot be done quickly. Young players often lose their bottles or cannot put their mouthguard back in their mouth before being called back to the ice. The simple process of taking a vital drink during a hockey game risks injury if the mouthguard cannot be quickly replaced back in the mouth when the player is called back to ice.
It would therefore be advantageous to combine the mouthguard with a fluid reservoir system that would enable the player to carry some fluids with them during play and hydrate as necessary.
U.S. Pat. No. 9,687,722 issued to Kennedy discloses a hydration mouthpiece that combines the mouthguard with a valve that can be closed when the user bites down on the mouthguard. It is also fitted with an intake tube that is intended to be connected to a water reservoir fitted with a bladder to pressurize the fluid.
This invention has a number of drawbacks. Firstly, it requires that the wearer bites down on the mouthguard in order to close the valve. Those that wear mouth guards during sport will recognize immediately that this is not a workable solution.
Firstly, mouthguard wearers do not apply continuous bite force to their guards. They clench and unclench their jaws periodically and move the guard back and forth between their teeth. Clenching their teeth for long periods to maintain the valve closed would quickly lead to jaw pain.
Secondly, hockey players often shout at each other during the game to identify their location. This cannot be done with their teeth clenched
Thirdly, hockey players instinctively shout in excitement when a goal is scored. It would thus be very dangerous if water is injected into the player's mouth during such periods of excited shouting, as the players would not be prepared for the rush of water. The water could be aspirated and could lead to unpleasant lung complications.
The invention of Kennedy is therefore unworkable in practice, and accordingly has not been implemented in the marketplace. For safety of use, the valve needs to be closed all the time and opened only when specifically directed by the user, not randomly by moving the teeth.
The present invention discloses a mouthguard with a valve that is closed and can be opened by the tongue, thus allowing pressurized fluid to enter the mouth. Once the tongue is released from the valve, the fluid automatically stops flowing and the tongue can be used to aid in swallowing. Bite of the teeth against the mouthguard has no effect on the function of the valve.
The invention comprises a mouthguard protective component connected via a tubular portion to a pressurized fluid reservoir. The mouthguard protective component includes a valve that is normally closed, preventing fluid passage from the fluid reservoir to the mouth, and can be opened via directed pressure of the tongue against a portion of the mouthguard protective portion.
The invention described above allows the user to safely place the mouthguard in their mouth, move it around with their teeth, and vocalize as may be necessary during the activity without concern for accidentally initiating the flow of fluid into the mouth. The combination of a mouthguard protective portion connected to a fluid reservoir enables the user to hydrate as necessary during the game and without the need to remove equipment. The use of a pressurized fluid reservoir enables effort free delivery of fluid into the mouth without the need for potentially exhausting suction during intense activity and rapid breathing.
This Summary is provided to introduce a number of concepts in a simplified form that are described below in the Detailed Description section. This Summary is not intended to identify key features or essential features of the subject matter claimed, nor is it intended to be used to limit the scope of the subject matter claimed. A more extensive presentation of the features, details and advantages of the present invention as defined in the claims is provided in the following written description of the various embodiments of the invention and illustrated in the accompanying drawings.
A Mouthguard with Hydration System is disclosed herein in conjunction with the accompanying figures.
The Mouthguard with Hydration System is comprised of a mouthguard protective component having an integral valve operated by the tongue, a pressurized fluid reservoir, and a flexible tube portion for providing fluid communication between the protective component and the fluid reservoir. In the illustrated embodiments of the present invention described herein, the fluid reservoir takes the form of a fluid container (deformable or rigid) or a fluid bag. Fluids stored in the reservoir may include, but are not limited to, water and sports drinks containing electrolytes.
The mouthguard protective component is preferentially fabricated from medical grade silicone rubber with a hardness appropriate for the application. It is shaped to fit between the teeth and can be of several sizes to accommodate users of different ages. It includes a spring component that keeps the valve closed until it is pressed upon by the tongue.
Throughout this specification, like reference numbers signify the same elements throughout the description of the figures.
According to a first embodiment of the invention, as shown in
The internal fluid handling passage are shown in
Valve 20 is shown in
Referring to
The ribbed connector 16 is sized to fit into the tubular portion 15 which is at the front of mouthguard protective component 10. The opposite end of the connector 16 fits into the delivery tube 39 which delivers pressurized fluid from deformable storage container 36 (see
Referring to
The valve 20 is kept closed by firm contact between the domed portion 21 and the rim of the hole 17 by the force of the pressurized fluid applied on the back face of the domed portion 21, as well as by the elastic preload bias of the arc-shaped spring 18. The resting state of the system is such that spring 18 is preloaded slightly to pull the domed portion 21 against the rim of hole 17, thus maintaining a fluid seal. Pressure applied by the user's tongue in a forward direction against the spring 18 is required to unseat the rounded portion 21 from the rim of the hole 17, and thus, enable pressurized fluid to pass around the valve 20 into the mouth of the user.
Mouthguard protective component 10 according to the present invention is both hands-free, as no action by the user's hands is required to enable the release of the fluid, as well as free-standing, in that no action by the user is required to prevent water from passing into the user's mouth. This is in stark contrast to the invention of Kennedy (U.S. Pat. No. 9,687,722) which requires the user to continually clench teeth against a valve in order to prevent water from passing into the user's mouth. In the present invention, water cannot enter the user's mouth unless the user's tongue is pressed against spring 18 with sufficient force to overcome the force on the closed valve and open it. This is inherently a safe system.
Pressurized fluid is passed through delivery tube 39 to valve 20 via the ribbed connector 16 that connects to tubular portion 15.
Additional measures can be used to secure the ribbed connector 16 within the tubular portion 15. For example, an additional clamping ring 19 (see
Delivery tube 39 connects to either a pressurized container 30 (
The pressurized container 30 or the pressurized bag 36 are preferably under a pressure that is sufficient to deliver the flow of fluid into the mouth, but not so much as to make it unsafe. The preferred pressure is between 35 to 50 kPa or (5 to 7.25 psi), although greater pressures are also acceptable as long as the container and all components are sized to contain the elevated pressures. Lower pressure is also acceptable, although that may lead to lower flow volumes.
Bag 36 is preferably sized so that it fits on a human's body strapped around the waist and anchored by the sports players' pants (see
Fluid can be delivered from bag 36 or any other suitable container by a motorized pump 40 (see
Bag 36 can also be pressurized by the use of a mechanical pump 41 (see
In an alternative embodiment, tubular portion 15 can be configured such that it is bent horizontally or vertically, or in any direction (see
