Dental and medical devices with light source and antimicrobial solution

Dental and medical devices with a light source and antimicrobial solution include an antimicrobial solution; a fiber optic cable that exposes the antimicrobial solution to light of a predetermined wavelength; and a solution holding apparatus that retains the lighted antimicrobial solution against the tissue. A method for antimicrobial treatment of a user includes retaining an antimicrobial solution in a solution holding apparatus; purposefully selecting a wavelength of light that reacts with the antimicrobial solution; providing the selected wavelength of light from an LED or laser or other appropriate light source; utilizing a fiber optic cable to expose the antimicrobial solution to the light; and utilizing the solution holding apparatus to hold the lighted antimicrobial solution against the user.

BACKGROUND OF THE INVENTION

The present invention generally relates to enhancement of antimicrobial solutions and more specifically to dental and medical devices with a light source and antimicrobial solutions.

Microbes exist that cause harm or disease in living tissues.

Light of certain wavelengths has been demonstrated to improve or “super-charge” the effects of certain antimicrobial or anti-microbial agents, creating a synergistic effect to destroy or inhibit microbial growth.

Most chemical reactions work best at a certain temperature. These ideal temperatures vary for each reaction. A “scalding chart” might indicate that water of 130 degrees is safe under an exposure of 30 seconds, but over that it causes burns. Water of 120 degrees may be safe up to 5 minutes.

It would be desirable to add light of certain wavelengths to a device that holds certain antimicrobial agents in close proximity to tissues, so a synergistic effect can be created to destroy or inhibit microbial growth on the tissues.

SUMMARY OF THE INVENTION

In one aspect of the present invention, a device for antimicrobial treatment of a tissue of a user includes an antimicrobial solution; a fiber optic cable that exposes the antimicrobial solution to light of a predetermined wavelength; and a solution holding apparatus that retains the lighted antimicrobial solution against the tissue.

In another aspect of the present invention, a device for antimicrobial treatment of a tooth of a user includes an antimicrobial solution; a fiber optic cable that exposes the antimicrobial solution to a predetermined wavelength of light; a dental tray that retains the antimicrobial solution in a cavity on a side of the tray, retains the fiber optic cable, and holds the lighted antimicrobial solution against the tooth; an external light source that utilizes either a light emitting diode (LED), laser, or any effective light source to provide the light of a predetermined wavelength; and a fiber optic connection cable that optically connects the light source with the fiber optic cable.

In yet another aspect of the present invention, a method for antimicrobial treatment of a user includes retaining an antimicrobial solution in a solution holding apparatus; purposefully selecting a wavelength of light that reacts with the antimicrobial solution; providing the selected wavelength of light from an LED, laser or any effective light source; utilizing a fiber optic cable to expose the antimicrobial solution to the light; and utilizing the solution holding apparatus to hold the lighted antimicrobial solution against the user.

DETAILED DESCRIPTION

The preferred embodiment and other embodiments, which can be used in industry and include the best mode now known of carrying out the invention, are hereby described in detail with reference to the drawings. Further embodiments, features and advantages will become apparent from the ensuing description, or may be learned without undue experimentation. The figures are not necessarily drawn to scale, except where otherwise indicated. The following description of embodiments, even if phrased in terms of “the invention” or what the embodiment “is,” is not to be taken in a limiting sense, but describes the manner and process of making and using the invention. The coverage of this patent will be described in the claims. The order in which steps are listed in the claims does not necessarily indicate that the steps must be performed in that order.

An embodiment of the present invention generally provides a device to hold solutions in contact with tissues, such as flesh or teeth, while the tissues and solutions are simultaneously being exposed to certain wavelengths of light. This device has a component that amplifies the effect of the antimicrobial solutions by using a certain wavelength of light. The antimicrobial solution may or may not be light activated at any given time. When the light is on, the solution is “supercharged” by the light. This synergistic effect eliminates or reduces more microbes than the solution acting alone.

Microbes exist that cause harm or disease in living tissues. By adding a light of certain wavelengths to a device that holds certain antimicrobial agents in close proximity to tissues, a synergistic effect can be created to destroy or inhibit microbial growth. In the oral cavity, this device could be a tray designed to cover the teeth and gingival. This tray would emit certain wavelengths of light that when combined with certain antimicrobial solutions in the tray would cause a synergistic antimicrobial effect. The light could be produced, for example, from a light emitting diode (LED) or laser. An external light source could be connected to the fiber optic cable in the solution holding apparatus with a fiber optic connection cable that may also include a fiber optic connection interface or plug.

Embodiments of the present invention may create another means to treat disease. Super charging antimicrobial solutions with certain wavelengths of lights may cause the solutions to eliminate or reduce microbes at a higher percentage than the solution alone.

Embodiments may create a synergistic effect between certain wavelengths of light and antimicrobial solutions that when applied to tissues eliminates or reduces disease causing microorganisms.

Embodiments of the present invention may consist of a solution holding apparatus or medium that emits certain wavelengths of light into the solution. When this light and solution combination is applied to tissues, a synergistic effect is created that reduces or eliminates microorganisms that cause disease. The essential components are 1. The solution holding apparatus 2. A light source 3. An antimicrobial solution.

Embodiments may utilize blue light, or another certain predetermined wavelength of light that supercharges the solution, with an exposure from a few second to minutes. Embodiments may also use an H2O2 solution, such as a gel, with concentration of 0.3 mM or any concentration of solution that is suitable as an antimicrobial agent.

In an embodiment, for safety, a “scalding chart” might indicate that water of 130 degrees is safe under an exposure of 30 seconds, but over that it causes burns. Water of 120 degrees may be safe up to 5 minutes. Hydrogen peroxide (H2O2), when it is exposed to a light of 400-500 nanometers wavelength, may kill 96% of microbes in less than 20 seconds. This solution may work best at 57 degrees Celsius (134 degrees F.).

Alternate embodiments may include heating elements that warm and further super-charge the antimicrobial solution. In embodiments, a device may contain heating or cooling components or both. In an embodiment, an antimicrobial solution may be preheated to an ideal temperature before it is exposed to synergizing light. For example, Hydrogen peroxide may preferably be exposed to a light of 400-500 nanometers at 57 degrees Celsius (134 degrees F.) for less than 20 seconds. Other chemicals may have different preferred temperatures.

In an embodiment, a chemical may be used without a reservoir. The chemical may be inserted directly into the body cavity and exposed to light by a fiber optic wand with a plurality of light emitting fibers. Embodiments of a carrier or reservoir may be the solution itself or a gel. This gel could be inserted in a body cavity with a catheter and exposed to the synergizing light by the same catheter or a different catheter. Delivery devices may include, but are not limited to, reservoirs, bandages, gels, solutions, head coverings, wraps, socks, stockings, hats, helmets, mists, suits, tents, probes, or catheters.

Further embodiments that retain a microbial solution and hold the solution against a portion of the user's body may include: bandage; a bucket; a body suit; a catheter; a helmet; a bowl; and a body part covering. Still further embodiments include methods for using and applying said devices to provide anti-bacterial treatment.

An embodiment of a tray for either upper or lower teeth of a user may be like a sports mouth guard, with an open top to be pressed around the teeth. The solution may be a gel, so that it can be retained in a tray for the lower teeth as well as a tray for the upper teeth. An embodiment may have two trays connected together to form a dual tray for simultaneous treatment of upper and lower teeth.

To make an embodiment, one could embed light emitting fiber optic fibers in a generally C-shaped dental tray that can hold certain antimicrobial solutions in a cavity on one side of the tray. A light source of certain wavelengths may be connected to the fiber optic fibers. The tray may be made of waterproof, safe material, such as plastic. The dental tray may be shaped by making an impression of the user's teeth, making a model from the impression, and then molding the tray over the model. The fiber optic cable may be embedded or inserted into the tray before or after the tray is molded. Light emitting elements on the cable may be added after the user's teeth have been measured to help align the elements or light terminations with the corners of the user's teeth.

The light terminations may be positioned on the fiber optic cable within the tray before use so that each light termination is located between adjacent teeth or adjacent to a tooth of the user. When the light source is activated, a synergistic effect may be created that causes the antimicrobial solution to become more effective than the solution without the light.

A side light emitting cable may be composed of one or more strands of fiber optic cable. The cable may have a clear coating or a partially-translucent coating, or the cable may have an opaque coating that is partially removed, such as along one side of the cable. The diameter of the cable may vary.

An embodiment of a device that covers a user's teeth and gingival, may include a tray that retains a microbial solution and holds the solution against the teeth and gingival; and a light source that emits a predetermined wavelength of light into the solution. Another embodiment of a device for a portion of a user's body may include a bandage or other device that retains a microbial solution and holds the solution against the portion of the user's body; and a light source that emit a predetermined wavelength of light into the solution.

FIG. 1depicts an embodiment of a dental device10. A light emitting fiber optic cable12may expose the antimicrobial solution14to a certain wavelength of light, such as a purposefully selected wavelength or frequency of light from an LED or laser. A tray16may hold the antimicrobial solution14. An embodiment may include a plurality of light terminations18or other light emitters on the light emitting fiber optic cable12. Each light termination18taps into the fiber optic cable12to pipe some of the light out the top of the termination, thereby emitting light into the antimicrobial solution14. The device may be adjustable, so that the terminations18can added or moved, or the quantity and locations of the light terminations18may be measured to fit an individual user. The light terminations18may be located within the tray16so that each light termination18is will be positioned between adjacent teeth or adjacent to a tooth of the user. The fiber optic cable may be opaque with light emitters spaced along its length, or may be at least partially translucent to emit light along its length.

In an embodiment, a the fiber optic cable12may connect to a light source20through a fiber optic connection cable22. The connection cable22may enter the tray16and optically connect with the fiber optic cable12through a fiber optic connection interface24so that the light source20can be attached and removed after use. An embodiment of the interface24may include an aperture in a wall of the tray16with a fiber optic connection cable22fixed to the fiber optic cable12. Another embodiment of the interface24may include a socket on the tray16that mates with a plug on the connection cable22so that the light source20can be attached and removed after use.

As depicted in the embodiment ofFIG. 2, an embodiment may be installed on an arch of human teeth. A user may have a lower row of teeth26having, for example, 14 teeth if 2 wisdom teeth have been removed. An embodiment of a device for this user may have30light terminations18or other light emitters connected to the fiber optic cable12in two rows of 15 each, so that there will be 4 terminations located at the corners of each tooth that surround the tooth with light emitters.

FIG. 3depicts another embodiment of a dental device30. A light emitting fiber optic cable32may expose the antimicrobial solution34to a certain wavelength of light. A tray36may hold the antimicrobial solution34. An embodiment may include a translucent or side-lighting fiber optic cable32to emit light along its length. The fiber optic cable32may connect to a light source20through a fiber optic connection cable22.

FIG. 4Adepicts an embodiment of a side-lighting fiber optic cable that includes a light-emitting inner core34and an outer shield36or coating. The outer shield36may be opaque, or partially translucent. The outer shield36only covers part of the light-emitting inner core34so that more light will be directed to the side. One side of the shielding may be removed to expose light down its length, similar to a banana with just one piece of peel removed.

As depicted in the embodiment ofFIG. 4B, the side-lighting fiber optic cable32may be emit light38of a certain wavelength or frequency to the side of the cable.
