LIGHT BASED THERAPY MOUTHPIECE

CLAIM OF PRIORITY

[0001] This applicant claims, pursuant to 35 USC 119, priority to, and the benefit of, the earlier filing date of US Provisional Patent Applicant serial number 63/276,592 filed on November 6, 2021, the contents of which are incorporated by reference, herein.

BACKGROUND OF THE INVENTION

FIELD OF THE INVENTION

[0002] This invention relates to the field of medical examination/diagnosis and treatment and more particularly to a devices utilizing Fluorescent Enhancement Theragnosis technology in the identification and treatment of medical conditions related to the oral cavity.

BACKGROUND INFORMATION

[0003] Light based therapy has emerged as a useful tool in locating and identifying infection or bacterial load with bodily tissues and reducing or eliminating the bacterial load within the tissues. Light based therapy is intended to provide for photoactivated disinfection, photodynamic therapy and photobiomodulation.

[0004] Photoactivated therapy is based on the use of inactive prodrugs whose biological activity is significantly increased upon exposure to light. See, for example, F. Reeling, , et al., Beyond Photodynamic Therapy: Photoactivated Cancer Chemotherapy, Curr. Med. Chem., 2018, 24, 4905-4950.

[0005] Photoactivated disinfection (PAD) is based on the concept of photodynamic therapy (PDT). PDT is a treatment method that is associated with the use of a light source and a photosensitizer (PS) that binds to cells and after absorption of light induces a chemical reaction that results in the release of radicals and singlet oxygen. See, for example, Husejnagic S, , et al., Photoactivated disinfection in periodontal treatment: A randomized controlled clinical split-mouth trial. J Periodontol. 2019;90:1260-1269.

[0006] Photobiomodulation (PBM) is a non-invasive method that contributes to pain relief and reduces inflammation, parallel to the enhanced healing and tissue repair processes. See, for example, Dompe, C., et al., M. Photobiomodulation— Underlying Mechanism and Clinical Applications. J. Clin. Med. 2020, 9, 1724.

[0007] The referred to research has found that the application of light within known wavelength ranges when applied to a surface is an effective means for reducing the activity of virus and bacteria. Such research, referred to, herein, as Fluorescent Enhancement Theragnosis (FET) technology, has proved itself to provide benefit to practitioners, such as dentist, doctors and surgeons, etc. in identifying bacteria that would not normally be viewable by the practitioner.

[0008] For example, FET has been found use in dental practice to apply light to a patient's mouth to identify virus and/or bacteria and to reduce the activity of virus/bacteria to limit the infection from the virus/bacteria.

[0009] Similarly, FET technology provides a doctor or surgeon the ability to view virus and/or bacteria on or within a patient and initiate appropriate remedial actions when necessary.

[0010] However, the light utilized in FET technology may be harmful to the human eye and, thus, eye protection is required for both the patient and the practitioner to avoid inadvertently viewing the harmful light.

[0011] Hence, there is a need in the industry for applying a light therapy to the oral cavity that provides for the detecting and healing of infection caused by excessive bacterial and/or viral load to a patient while preventing inadvertent viewing of the applied light.

SUMMARY OF THE INVENTION

[0012] Disclosed is device to apply light therapy to infection such as bacteria and viruses within an oral cavity of a patient wherein the device is adjustable to provide a customized fit of the device to the user.

[0013] In accordance with the principles of the invention, a light based therapy device is disclosed to provide for fluorescence based identification and treatment of virus/bacterial within an oral cavity, wherein the light based therapy device comprises at least one mouthpiece comprising a plurality of lighting sources positioned on at least one of: a top surface, a bottom surface, at least one lateral surface between the top surface and the bottom surface and the back (or flat) surfaces of the at least one mouthpiece, a connector configured to provide an electrical energy to the plurality of lighting sources, a control board configured to control signals to cause the electrical energy to be provided to selected ones of the plurality of lighting sources and a bite element configured to provide an indication of placement the mouthpiece addition.

[0014] In accordance with another aspect a light based therapy device is disclosed to provide a light treatment to an oral cavity of a patient, wherein the light based therapy device comprises a rear mouthpiece, and a front mouthpiece that are positioned on opposite sides of the patient's teeth, a bite element positioned between the rear mouthpiece and the front mouthpiece wherein the patient engages the bite element to retain the light based therapy device in position, a connector configured to provide electrical energy to a plurality of selected ones of a plurality of lighting sources associated with the rear mouthpiece and the front mouthpiece, wherein at least one of the rear mouthpiece and the front mouthpiece is slidable with respect to the connector.

[0028] FIG. 1 illustrates a perspective view of a first exemplary embodiment of an oral cavity light-based therapy device 100 in accordance with the principles of the invention.

[0029] Light based therapy device 100 comprises a mouthpiece element 110 that may be formed, as illustrated, into a shape that is substantially conformal to an inner shape of a patient's mouth. Mouthpiece 110 may be composed of a flexible material (e.g., silicon) that enables mouthpiece 110 to conform to the surface of a patient's teeth, for example. Alternatively, mouthpiece 110 may be composed of a pliable or adaptable material that may be molded into a desired shape or configuration either when placed within the oral cavity or fitted against an inner surface of a patient's teeth.

[0030] In accordance with the principles of the invention, mouthpiece 110 further comprises a plurality of lighting sources (e.g., light emitting diodes) 120 positioned along at least one surface of mouthpiece 110, wherein the plurality of lighting sources 120 are positioned to emit light substantially perpendicular to the surface upon which the lighting sources or positioned. In the illustrated embodiment, lighting sources 120 are positioned on top surface 121, bottom surface 122, external lateral surface 123 and internal lateral surface 124 between top surface 121 and bottom surface 122. Although not shown, it would be recognized that lighting sources 120 may be positioned on back or flat end surfaces 125 to enable light to be directed to the back of the oral cavity.

[0031] The plurality of lighting sources 120 may be configured to emit light in one or more of a plurality of light wavelength bands. For example, an ultra-violet wavelength range (10- 380 nanometers (nm)), a visible wavelength range, which may be one of white (i.e., 380-750 nm) or one or more of a color light (e.g., violet - 380-435 nm; blue - 435-495 nm; cyan - 495-520; green - 420-570 nm; yellow - 570-590 nm; orange - 590-620 nm and red - 620- 750 nm) and an infra-red wavelength range.

[0032] Although not shown in detail, it would be recognized by those skilled in the art that each of the plurality of lighting sources 120 may be composed of one or more light sources arranged in an exemplary configuration (e.g., matrix). For example, the illustrated lighting sources 120 may be composed of four (4) individual light sources (e.g., light emitting diodes), wherein one of the light sources may emit light in a white wavelength range, a second one of the light sources may emit light at a first wavelength in a blue wavelength range, a third one of the light sources may emit light at a second wavelength in the blue wavelength range and a fourth one of the light sources may emit light in an orange wavelength range. The light emitted by the selected one of the light sources within each of the lighting sources 120 may be emitted individually, concurrently and or sequentially.

[0033] Although lighting sources 120 are discussed with regard to a combination of four light sources, it would be recognized that the number of light sources per lighting source 120 may be increased and decreased without altering the scope of the invention. Similarly, the wavelength ranges of the light sources (i.e., the light emitted) within each of the lighting sources 120 may be altered from the exemplary wavelength ranges disclosed, herein, without altering the scope of the invention claimed.

[0034] In one aspect of the invention, mouthpiece 110 may comprise a heat-transferrable material (i.e., cooper, aluminum, etc.) that may be encased in a waterproofing material (e.g., silicon). Mouthpiece 110 may then be formed or molded into a desired shape to allow for proper positioning of mouthpiece 110 in the oral cavity. Light emitted by the lighting sources 120 may be transmitted through an optically clear material toward tissue within the oral cavity. Alternatively, the waterproofing material may be translucent or frosted to provide for a more diffuse output of the light emitted.

[0035] Lighting sources 120 may be positioned on printed circuits boards (not shown) that may be positioned on an encased heat transferable material (e.g., cooper, aluminum, etc.), within mouthpiece 110. The heat transferrable material within mouthpiece 110 may further provide for the transmission of electrical energy to lighting sources 120 while removing heat generated by lighting sources 120 from the oral cavity. Alternatively, lighting sources 120 may be positioned on a flexible printed circuit board (not shown) that may be formed or molded into a shape that provides for a desired placement of lighting sources 120 within the oral cavity.

[0036] Further illustrated is connection 130 that provides a path for electrical energy to be supplied from control module 140 to lighting sources 120. Control module 140 may comprise a power source or power supply (not shown) (i.e., a conventional battery (e.g., alkaline), a rechargeable battery and/or an AC/DC converter that converts alternating current to direct current). Connection 130 may further include a protective sheathing composed of a material that provides protection for the electrically elements within connector 130. Within connector 130 a heat conductive material may be included that provides a heat conductive path from which heat generated by the operation of lighting sources 120 may be drawn from the oral cavity.

[0037] Although control module 140 is shown remote from mouthpiece 110, and connected through connection 130, it would be recognized that connection 130 may be such that control module 140 is positioned substantially proximal to mouthpiece 110, as will be discussed.

[0038] In accordance with the principles of the invention, control module 140 may further include electrical elements (i.e., resistors, capacitors, integrated circuits, etc.) (not shown) positioned on a control board (i.e., printed circuit board) (not shown) that may be used to control an application of a voltage or current to selected ones of the plurality of lighting sources 120 on or within mouthpiece 110.

[0039] In one aspect of the invention, control module 140 may include a user interface that enables a user to manually provide input instructions for the application of a voltage or current, the time duration of the application of such voltage or current, the level of such voltage or current and/or the color or color temperature to selected ones of the plurality of lighting sources. The control module 140 may further determine whether the voltage or current are applied in a pulsed (e.g., pulse repetition rate, pulse duration, pulse on/off ratio (i.e., duty cycle) etc.) or a continuous manner. For example, Pulse Width Modulation (PWM) is a well-known pulse technique where the pulse duration (or width) is altered between pulses to provide a longer or a shorter "ON" time during the duration of the time a signal is to be active (i.e., pulse mode duration). In this example, longer or shorter times for a light to be emitted for the duration of the time light is to be emitted.

[0040] In an alternative aspect of the invention, control module 140 may include a plurality of pre-set light setting that are set based on a desired light-based treatment for a known condition.

[0041] Further illustrated is bite elementl50 position proximal to mouthpiece 110 along connector 130 Bite element 150 provides a region upon which a patient may place their teeth to retain mouthpiece 110 in a proper relationship within the patient's oral cavity. [0042] In one aspect of the invention, bite element 150, which may be made of a rubber or other similar material (e.g., silicon), is slidable along wire connection 130. The slideability of bite elementl50 is advantageous as it enables the placement of a front surface of mouthpiece 110 to be substantially adjacent a patient's front teeth. For example, mouthpiece 110 may be adjusted within the oral cavity to be substantially adjacent the rear surfaces of a patient's teeth by providing a light pressure onto bite element 150 while sliding mouthpiece 110 into position. Alternatively, mouthpiece 110 may be placed deeper into the oral cavity to position light sources 120 closer to a point of infection.

[0043] In addition, bite element 150 may comprise a pressure sensor, a contact sensor, a proximity sensor, or other similar type sensing element (not shown) that may provide (or provides) an indication to control module 140 that bite element 150 has been engaged. Control module 140, receiving the provided indication of engagement of bite element 150 (and, hence, the proper positioning of mouthpiece 110), may provide (or provides) voltage to selected ones of the plurality of lighting sources 120. Without the indication of proper placement (i.e., engagement of a user's teeth) from bite element 150, control module 140 is inhibited from providing a voltage to the plurality of lighting sources 120.

[0044] In accordance with the principles of the invention, an image capture device (e.g., a camera, a CCD element, etc.) 180 may be incorporated onto (or within) interior lateral surface 124 to allow for the capturing of images or video of the oral cavity before, during and after treatment by the light-based therapy system 100.

[0045] Images captured by image capture device 180 may be transmitted, via connector 130, to a control board (not shown) within control module 140, wherein the images may be subsequently transmitted through a wireless or wired transmitter to a display device (not shown) or stored on a storage media (not shown). Protocols for wireless (e.g., BLUETOOTH, Wi-FI, etc.) and wired (e.g., RS-232) communications are well-known in the art and a detailed discussion of transmitting/receiving date utilizing these or similar (e.g., NFC) protocols is not believed necessary in discussing the invention disclosed, herein.

[0046] in accordance with the principles of the invention, a filter 190 may be placed before image capture device 180, wherein filter 190 limits the wavelength range captured by image capture device 180.

[0047] In one aspect of the invention, filter 190 may be configured to block the viewing or capturing of light wavelength ranges in a first wavelength, for example. In one aspect of the invention, filter 190 may be configured to block the wavelength region of light emitted by lighting sources 120, while allowing light associated with one or more specific or desired wavelength regions to be viewed or captured. In one aspect of the invention, filter 190 may comprise a notch filter configured to block wavelengths emitted by selected ones of said plurality of lighting sources 120 while allowing wavelengths outside of the notch filter range to pass through to image capture device 180. Alternatively, filter 190 may comprise a long pass filter that blocks light emitted by selected ones of said plurality of lighting sources 120 below a known wavelength while allowing wavelengths above the known wavelength. As an example, lighting sources 120 may emit light in a blue light wavelength range and in a white wavelength range, wherein filter 190 may possess filter characteristics that form a notch filter to blocks the blue light from being captured by image capture device 180, while allowing the white light, excluding that wavelength region blocked by the notch filter, to be viewed by the image capture device 180. [0048] FIG. 2 illustrates a front view of oral cavity light-based therapy device 100 shown in FIG. 1, wherein the view is taken from the oral cavity outwardly toward device 100. In this illustrated embodiment is shown internal lateral surface 124 of mouthpiece 110 and control module 140, wherein lighting sources 120 are positioned on each of top surface 121, bottom surface 122, external lateral surface 123 and internal lateral surface 124 of mouthpiece 110.

[0049] Further illustrated is mask 210 and control module 140 wherein mask 201 blocks light emitted by lighting sources 120 from exiting the patient's mouth, when control module 140 /mask 210 combination is pressed against the patient's mouth. In this aspect of the invention, mask 210 may comprise a flexible material that may be pressed against a patient's lower face (e.g., the mouth area) that is configured to block light emitted by lighting sources 120 from exiting the oral cavity.

[0050] Alternatively, mask element 210 may be a separate element that may be slidable with respect to connector 130 to allow the positioning of mask element 210 adjacent the lower face area of a patient after mouthpiece 110 is inserted into the oral cavity.

[0051] FIG. 3 illustrates a top view of light-based therapy device 100 shown in FIG. 1. In this illustrated embodiment is shown connector 130 and bite element 150, which is positioned proximal to a front portion 310 of external lateral surface 123. Further illustrated are lighting sources 120 positioned on a top surface 121, external lateral surface 123 and internal lateral surface 124 of mouthpiece 110. In one aspect of the invention, mask 210 may include a contact sensor, a proximity sensor, a heat sensor, etc., that indicates mask 210 is properly positioned with respect to a user. The sensor may provide an indication to the control module 140 that indicates the proper positioning of mask 210 with respect to the use or the patient. In this case, control module may be configured to provide electrical energy to selected ones of the lighting sources after receiving the indication of proper position of mask element 210.

[0052] FIG. 4 illustrates a side view of light-based therapy device 100 shown in FIG. 1, wherein lighting sources 120 are positioned on top surface 121, bottom surface 122 and external lateral surface 123. Although not shown, and as previously discussed, lighting sources 120 may be positioned on the end (back or flat) surface 125 positioned between top surface 121 and bottom surface 122.

[0053] Further illustrated is encasing material 410, which as discussed, may be composed of a waterproofing material (e.g., silicon) that prevents liquid from contacting the lighting sources 120, the associated electrical components. Encasing material 410 further allows for the sterilization of the mouthpiece 110. In one aspect of the invention, encasing material 410 may be composed of an optically clear material. In another aspect of the invention encasing material 410 may comprise a translucent or frosted material. In this case, the light emitted by lighting sources 120 may be diffused as it passes through a translucent or frosted encasing material 410.

[0054] FIG. 5 illustrates a perspective view of a second exemplary embodiment of an oral cavity light-based therapy device 500, in accordance with the principles of the invention. [0055] In this illustrated second exemplary embodiment, light-based therapy device 500, similar to the light-based therapy device 100 shown in FIG. 1, comprises control module 140, connector 130, bite element 150 and mouthpiece 505, wherein mouthpiece 505 comprises mouthpiece 110, shown in FIG. 1 (referred to, hereinafter, as rear mouthpiece 110) and front mouthpiece 510. Front mouthpiece 510, similar to rear mouthpiece 110, comprises a plurality of lighting sources 120.

[0056] In this illustrated embodiment, front mouthpiece 510 is positioned along connector 130 such that bite element 150 is positioned between rear mouthpiece 110 and front mouthpiece 510. Front mouthpiece 510, similar to rear mouthpiece 110, may be composed of a flexible or a pliable material that may conform substantially to a front portion of the oral cavity (e.g., the front surfaces of a patient's teeth). In one aspect of the invention front mouthpiece 510 may further include a heat-transferrable material similar to that described with regard to rear mouthpiece 110.

[0057] Front mouthpiece 510 further includes a plurality of lighting sources 120 arranged, in this example, on top surface 521, a bottom surface 522 and a rear surface 524 of front mouthpiece 510. Although not shown, it would be recognized that lighting sources 120 may be incorporated onto the back (or edge) surfaces 525 of front mouthpiece 510, as discussed with regard to rear mouth piece 110, without altering the scope of the invention claimed. [0059] In one aspect of the invention, rear mouthpiece 110 and front mouthpiece 510 may be adjusted to substantially engage rear and front surfaces, respectively of a patient's teeth, for example, by the movement of rear mouthpiece 110 and/or front mouthpiece 510 with respect to bite elementl50.

[0060] In accordance with the principles of the invention, rear mouthpiece 110 and front mouthpiece 510 may be positioned by the illustrated adjustment cable 520 to alter the position of one or both of rear mouthpiece 110 and front mouthpiece 510. For example, by adjusting the distance between rear mouthpiece 110 and front mouthpiece 510, rear mouthpiece 110 and front mouthpiece 510 may be placed in a substantially adjacent relationship to the rear and front surfaces of a patient's teeth. Alternatively, front mouthpiece 510 may be placed adjacent the front of the patient's teeth, while rear mouthpiece 110 may be extended toward a rear portion of the patient's oral cavity.

[0061] Although an adjustment cable 520 is shown, to cause movement of at the illustrated elements of mouthpiece 505, it would be recognized that other forms of movement control may be incorporated into the illustrated second exemplary embodiment of a light therapy device. For example, rear mouthpiece 110 and front mouthpiece 510 may include a screw thread, which may be positioned on a screw that allows the adjustment of the position of one or both of rear mouthpiece 110 and front mouthpiece 510.

[0062] FIG. 6 illustrates a front view (when viewed looking outward from inside an oral cavity) of the second exemplary embodiment shown in FIG. 5. Similar to the configuration shown in FIG. 2, lighting sources 120 are shown on an internal lateral surface 124 of rear mouthpiece 110. Further shown is the external lateral surface 523 and back surface 525 of front mouthpiece 510.

[0063] FIG. 7 illustrates a top view of the second exemplary embodiment of the light-based therapy device shown in FIG.5 showing the adjustable movement of front mouthpiece 510 with respect to bite element 150.

[0064] In this illustrated exemplary aspect of the invention, front mouthpiece 510 is shown in a first position or initial position (referred to as 510a) and then slide along connector 130 to a second position (referred to as 510b), which places mouthpiece 510 substantially adjacent a front surface of a patient's teeth (not shown). As shown, the shape of front mouthpiece 510 may be altered to conform to the front surface of the patient's teeth as front mouthpiece 510 is positioned substantially adjacent the patient's or user's teeth. [0065] Light emitted by one or more lighting sources 120 positioned on top surface 521, bottom surface 522, interior surface 524 and flat surface 525 may emit light toward tissue (e.g., gums) at or near the front surfaces of a patient's teeth.

[0066] Although not shown in FIG. 7, it would be recognized that rear mouthpiece 110 may be similarly adjusted with respect to bite element 150, as discussed previously.

[0067] FIG. 8 illustrates cut-away side view of the second exemplary embodiment of mouthpiece 505 shown in FIG. 5 in accordance with the principles of the invention.

[0068] In this illustrated embodiment, outer surface 523 of front mouthpiece 510 fails to include lighting elements 120, whereas the outer surface 123 of mouthpiece 110 includes lighting elements 120 (FIG. 4). Although the outer lateral surface 523 of front mouthpiece 510 is shown to not include lighting elements 120, it would be in the knowledge of those skilled in the art to incorporate lighting elements 120 onto (or into) the outer lateral surface 523 of mouthpiece 510 to provide light therapy to the inner surfaces of the user's lips. Such modification of the configuration shown, herein, has been contemplated and considered by the inventors to be within the scope of the invention claimed.

[0069] In summary, a mouthpiece element has been disclosed that provides for the placement of light emitting elements within an oral cavity of a patient or a user wherein an adjustment means is used to customize the position of the mouthpiece element(s) with respect to the patient's or user's oral cavity. In one aspect of the invention, the mouthpiece element(s) may be positioned substantially adjacent to the teeth of the patient or the user. In another aspect of the invention, the mouthpiece element may be positioned extended into the oral cavity to provide light therapy surrounding or near the patient's or user's throat. In addition, a control mechanism is disclosed that provides for the safe application of a voltage to the light emitting elements within or on the surface of the mouthpiece element(s). In one aspect of the invention, a facial mask element may be incorporated into the mouthpiece element (110 or 505) to reduce the possibility of the viewing of those wavelengths of the lighting elements that may be harmful to the eyes.

[0070] Although the invention disclosed herein discusses specific wavelengths that are produced with currently available LEDs (i.e., non-lasing light emitting diodes and laser diodes), it would be recognized that the specific wavelengths absorbed and/or reflected may be changed and/or added to without altering the scope of the invention. In addition, it would be known in the art that the specific wavelengths discussed, herein, represent a band of wavelengths centered on the wavelength values presented herein to account for divergence of the wavelength generated by the LED during the generation of the light and/or the operation of the LED, wherein the light generated is represented as a nominal value.

[0071] The invention has been described with reference to specific embodiments. One of ordinary skill in the art, however, appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims.

Accordingly, the specification is to be regarded in an illustrative manner, rather than with a restrictive view, and all such modifications are intended to be included within the scope of the invention.

[0072] Benefits, other advantages, and solutions to problems have been described above regarding specific embodiments. The benefits, advantages, and solutions to problems, and any element(s) that may cause any benefits, advantages, or solutions to occur or become more pronounced, are not to be construed as a critical, required, or an essential feature or element of any or all of the claims.
