SYSTEMS, APPARATUSES, AND METHODS FOR TREATING BRUXISM, APNEA, AND SLEEP DISORDERS

Abstract

Systems, apparatuses, and methods for aiding a user in ceasing or at least ameliorating sleep or awake bruxism, or apnea, or snoring. The unit is fully enclosed against fluid incursion and placeable between a user's teeth and adjacent cheek, such as while the user is sleeping or awake. A flange extends from a lateral side of the unit, so as to fit between the user's upper and lower teeth and locate the unit in place. The unit includes a circuit that, when completed, such as by the user clenching his/her teeth, causes a mild vibration mechanism to activate and cause a sensation which signals the user to stop clenching his/her teeth. The vibration is preferably such that, if the user is sleeping, the user is not fully awakened but mildly startled to break whatever condition has set off the unit.

DETAILED DESCRIPTION OF THE INVENTION

[0043] Detailed embodiments of devices, systems, and methods are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of the devices, systems, and methods, which may be embodied in various forms. Therefore, specific functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

[0044] FIGS. 1-3A-B illustrate a device 10 adapted to provide a signal/sensory indication to a user in response to, in one aspect, the user clenching his/her jaw, or clenching or grinding his/her teeth 102, for example during bruxism. According to other aspects, such a device functions as a “chassis” for use in treating apnea, snoring, and potentially other issues. The device 10 may be used as a training device that provides a reminder to the user in the form of a vibration sensation, an audible sound, an olfactory sensation, a visual indication, a taste sensation, or other sensory indication in response to the physical activity of teeth clenching or bruxism. As illustrated in FIG. 1, the device 10 includes a disc-shaped portion 12 shaped and formed to nest between a cheek 104 and adjacent teeth 102; hence the reference to the so-called “Puck.” The device 10 also includes a bite portion or tab 14 that extends and is adapted to situate between the user's teeth 102. When the user clenches his/her teeth 102 the user places pressure on the tab 14. The tab 14 serves to otherwise position and locate the device 10 in its desired place.

[0045] The disc-shaped portion 12 and the tab 14 or bite portion are shaped to both maintain patient comfort while anchoring the device 10 in the user's mouth at an optimal position for proper function. For example, the disc-shaped portion 12 is shaped to comfortably fit between the user's cheek 104 and teeth 102, and allows the device 10 to maintain position in the user's cheek pocket. Similarly, the length of the tab 14 is designed to prevent the device 10 from being pushed out from between the user's teeth 102 into the user's cheek pocket, and to limit interference with the user's tongue.

[0046] The tab 14 is compressible and includes a mechanism that when compressed activates electronic components in the disc portion of the device 10. When activated, the electronic components (for example, including a power source, such as battery 16, and a responsive device, such as vibrator 18, deliver a vibrating sensation to the user. This vibration sensation provides a signal, such as a biofeedback signal, to the user. That feedback can be in the instance of teeth clenching, or detected apnea (interruption of breathing), or snoring. As will be further described hereafter, there are anticipated associated apparati which will serve to detect conditions beyond bruxism that the device, system and method are intended to ameliorate. So, in the case of bruxism, the device allows the user to take corrective action. The cessation of clenching quickly becomes a natural and automatic response to the vibration reminder. In this way, the device 10 provides a biofeedback response useful in training the user to correct teeth clenching/bruxism.

[0047] The device 10 may be formed having a continuous outer wall 20. In this embodiment, such outer wall 20 is formed from a deformable material, preferably medical grade plastic common to dental applications, such that when a user clenches his/her teeth 102 the tab 14 deforms. Outer wall 20 defines an inner chamber 22 which is formed within both the disc-shaped portion 12 and the tab 14. A housing 24 is carried in inner chamber 22, such housing encapsulating the vibrator 18 and the battery 16. The housing 24 completely surrounds the battery 16 and the vibrator 18 such that if outer wall 20 is pierced or otherwise ruptures, the battery and the vibrator will remain encapsulated and protected against fluid incursion. The housing 24 is preferably formed in two parts which snap together to allow assembly of the battery 16 and vibrator 18 and associated electrical conductors prior to enclosing the housing in the outer wall 20.

[0048] A diaphragm or thinned section 26 is formed in housing 24 on the face of the housing which is oriented in the direction of tab 1 (i.e., inboard). The thinned section 26 is shaped such that it repeatably bends or deforms in the same direction, namely in the direction of battery 16. The thinned section 26 is bendable or deformable and facilitates activation of the vibrator 18 as described below. In this embodiment, the thinned section 26 is a single crease in housing 24. A contact element, for example, electrical conductors 28 or a signal generator, which are in electrical communication with vibrator 18, are mounted to housing 24 proximate the inner side of thinned section 26. Battery 16 is positioned adjacent electrical conductor 28, such that when a user is not clenching his/her teeth, the electrical conductor is spaced from battery 16 in an open circuit position. When a user does clench his/her teeth, thinned section 26 bends, thereby pushing or moving the electrical conductor 28 against battery 16 which completes a circuit, allows a signal to flow to vibrator 18, and causes vibrator 18 to activate. As such, when tab 14 is not deformed, a gap is present between electrical conductor 28 and battery 16, which gap is bridged by movement of thinned section 26 which is facilitated by deformation of tab 14.

[0049] As will be discussed below, in its form for treating apnea or snoring, a receiver will take the place of the signal generator, or be in addition to the signal generator. That receiver wirelessly interconnects with an external appliance/apparatus, which can send a signal to the receiver to then actuate the vibrator 18.

[0050] Turning back to the chassis, sometimes referred to herein as a puck (due to its general overall external look in this particular form), Chassis/device/puck 10 uses a tab 14 that has a generally elongate cross-section, such as an oval-shaped cross-section. This elongate shape helps to orient biofeedback device 10 between the teeth, wherein the device 10 will tend to naturally rotate such that the longer axis of the tab 14 will orient generally parallel with the user's teeth.

[0051] Disc-shaped portion 12 is formed having an aperture 34 (FIG. 2A, 2B) passing therethrough, such that aperture 34 forms a hole through the outer flange portion of biofeedback device 10. Aperture 34 does not provide access to internal chamber 22, since this would allow saliva and other fluids to potentially spoil the internal electronics. Instead, aperture 34 allows air to pass through biofeedback device 10 in the case where biofeedback device 10 becomes lodged in the user's airway. In this way, aperture 34 is a safety feature which prevents suffocation.

[0052] In one embodiment, a pair of elongate arms 30 extend from housing 24, wherein the arms are spaced on either side of thinned section 26. Arms 30 extend within internal chamber 22 in tab 14. Arms 30 are positioned parallel one another. Arms 30 are wider than they are thick, such that a space is formed between the arms when tab 14 is not clenched. When tab 14 is clenched, arms 30 are forced toward each other which causes thinned section 26 to deform and to push electrical conductor 28 against battery 16. The arms 30 are preferably oriented parallel with the longer axis of tab 14, such that a user's bite motion will cause the arms 30 to move toward each other, rather than biting on the edges of the arms.

[0053] As described above, the device 10 uses a lever-type mechanism, which has one or more elongated elements, arms 30, in the bite area that, when moved toward the longitudinal axis of the bite area, cause a movement of the contact element, electrical conductor 28, so as to close a circuit and thereby generate a signal. Such a signal can be an electrical current, to actuate the vibrator 18, for example. In one such embodiment described, there are two elongated arms 30 connected through a base, thinned section 26, of what constitutes a u-shaped piece. As the arms 30 bend toward one another under influence of teeth moving toward engagement (clenching), the base flexes. The base flexes outwardly (essentially bulging), to thereby move the contact element to close a circuit. The base could just as easily move inwardly, and thereby lever the contact to a closed position.

[0054] The embodiments described above are very similar in concept in treating bruxism, that a bulging movement physically engages the contact element to close a circuit. One of elongate members 32 or elongate arms 30 defines an actuating member. Actuating member is such that, when a user bites tab 14, the actuating member is actuated in a way that completes a circuit and activates vibrator 18. Housing 24 is optional; the electrical components may be placed directly within inner chamber 22 and actuated directly by the actuating member.

[0055] The devices 10 described above involves a single integrated unit which is emplaced in a person's cheek. All of the electronics, power source and indicator device for providing an impulse to the user of teeth clenching (e.g., a vibrator), are contained in that integrated unit.

[0056] The embodiments are not limited to an integrated device 10 with all operational elements located in a person's cheek. As illustrated in FIG. 8, the clenching action, or some other action, may result in a signal transmitted, such a through Bluetooth, infrared or radio frequency communication, from the action of the bite area to a remote station or device, such as a computer 50, a mobile phone or handheld device 52, or a smart watch 54, or a web engaged apparatus such as a voice controlled interactive personal assistant 56 (e.g., an Alexa apparatus), among other things. The signals can be generated by the device 10 for recording, use or analysis by such external apparati, as well as for sending signals to the device 10, which then provides some stimulus to the person. Besides vibratory responses, the stimulus could be a visual stimulus, audible sound or alarm, for example, or it could be another physical stimulus, such as a vibration through some mechanism engaging or attached to a person (e.g., the smart watch 54), but which is remote from the general housing of the device 10. Additionally, the device 10 may include circuitry adapted to receive and transmit data and other information to the remote station or external apparatus.

[0057] A functional block diagram of components of the device 10 in one form are described with reference to FIG. 5. As illustrated in FIG. 5, the device 10 may include a controller 62 and a memory 58 coupled to the controller 56. The device 10 also includes interface circuitry 60 which may include, for example, a universal serial bus (USB) port, Firewire port, infrared data transmitter, radio frequency data transmitter, Bluetooth, or other communication technique. The interface 60 allows the device 10 to communicate with other external appliances such as, those illustrated in FIG. 8. The interface 60 may also be used to power or charge the power source or battery 16 of the device 10 in a wireless fashion.

[0058] The interface 60 and memory 58 may be coupled to the controller 62 by one or more internal signal paths. The controller 56 may be a processor, a control circuit, etc., and may facilitate communication between various components of the device 10 and control operation of various electrical components of the device 10. In one aspect, the memory 58 can store data or computer programs for use with the device 10. For example, the memory 58 may be used to store instructions for the vibrator 18. It is contemplated that the biofeedback may be proportional, in some respect, to the amount of teeth-clenching that is occurring (i.e., the force being applied to the bite portion, tab 14). Accordingly, as the force applied by the closing teeth increases, the stimulus (i.e., vibration by the vibrator 18) applied to the user likewise increases. Additionally, controls can be provided to allow the user to adjust how the system will respond. These could be amplitude adjustments as indicated in the preceding paragraph, whereby the impulse to the user varies with clenching force.

[0059] For example, the device 10 may have one or more settings relating to duration, amplitude, etc. of the vibration. The device 10 may use usage input to modify the input into a variety of outputs based on the settings. The setting could be based on clinical data, guess and check, patient demographics, etc. As an example, one bite for 1 second could trigger 2 seconds of vibratory output. In another example, the vibration may have a sinusoidal decay to ease the user back to sleep. These settings may be programmed by the user via the computing device(s) illustrated in FIG. 8, or even based on activating the vibrator in a certain sequence to enter a ‘setup’ mode. The device 10 can then emit a vibration to the user to communicate that it has or has not received the inputs when in ‘setup’ mode.

[0060] The memory 58 can also store data relating to a use of the device 10. For example, the memory 58 may record duration of teeth clenching, pressure/force of teeth clenching, time, intensity, etc., to create a log or history of the teeth clenching of the user. This data may then be uploaded or transmitted to one or more of the computing devices illustrated in FIG. 8. Without limitation, the memory 58 can include a non-transitory computer-readable recording medium, such as a hard drive, DVD, CD, flash drive, volatile or non-volatile memory, RAM, or any other type of data storage, for example.

[0061] Further details relating to an embodiment as adapted for the treatment of bruxism can be found in U.S. Pat. No. 9,827,137, the disclosure of which is hereby incorporated by reference in the present application.

[0062] But as contemplated herein, the invention encompasses more than just the treatment of bruxism. Turning to FIG. 6, an embodiment using the device/chassis 10 is adapted for the treatment of sleep apnea. Here, one form of the invention uses a blood or pulse oximeter 70, which is intended to be applied to a user in standard fashion. It is known that in instances of prolonged breath stoppage, the blood oxygen level drops. If that level falls below a threshold, this can be an indication of an apnea episode. The oximeter thus functions as a trigger to reverse the apneic episode, that is, startle the sleeper, as through actuation of the vibrator 18 of the device 10, and reinstitute breathing.

[0063] In this form of the invention, the oximeter 70 would advantageously be connected to its own or an interconnected signal generator. The signal generated by the oximeter 70 is then transmitted to the device 10, for action. Device 10 therefore has a receiver 72 for the signal therein; this receiver is schematically illustrated as an optional feature of the block diagram FIG. 5.

[0064] There are other physiological phenomena that can be detected indicative of apnea, such as pulse rate, respiratory rate. These can also be used as thresholds for instituting action to break the episode. Also, the disclosure herein can be extended to deal with issues such as suffocation, and even Sudden Infant Death Syndrome.

[0065] The device 10 as a chassis may remain as generally described in its form for the treatment of bruxism. However, if used only for the treatment of some other issue, such as apnea or snoring, the tab 14 need not be adapted for the detection and response to teeth clenching. A modified tab 14′ therefore is merely for positioning.

[0066] Turning now to FIG. 7, what is schematically depicted is an adaptation for use in treating snoring. In this illustration, an Alexa-like apparatus 56 is located near or in the vicinity of the user, basically within a distance so as to hear the user. Apparatus 56 is programmed to detect the sounds S of an individual snoring, which may be a sonic or tonal level indicative of that person engaging in snoring. The apparatus 56 then sends a signal triggering the device 10 to provide a vibratory “nudge,” and truncate the snoring episode.

[0067] As in the instance of apnea treatment, the tab 14 need not have contents adapted for teeth clenching, as its function here is also for location primarily.

[0068] Notably, and using the characteristic of this disclosure as a chassis 10, the device 10 can be adapted to contain all of the foregoing adaptations for bruxism, apnea and snoring, or just one or more of the foregoing. The chassis may be adapted to receive modules that contain the elements for treatment of a specific issue. This could take the form of a kit, where multiple different treatment modules can be swapped in and out, depending upon the need. The kit could therefore include the external peripheral apparati required.

[0069] Although systems, apparatuses, devices, and methods have been described and illustrated in connection with certain embodiments, many variations and modifications will be evident to those skilled in the art and may be made without departing from the spirit and scope of the disclosure. For example, the vibrator may be a piezoelectric device, a linear actuator, etc. Similarly, the trigger mechanism for causing the vibrator to activate may be a pressure sensitive switch or a contact switch. The disclosure is thus not to be limited to the precise details of methodology or construction set forth above as such variations and modification are intended to be included within the scope of the disclosure, and the Claims hereafter.
