The invention relates generally to a dental mirror, and snore particularly to a dental mirror that is configured to receive air from a standard dental compressed air source to de-fog the mirror surface and help remove debris therefrom.
By way of background, mouth mirrors are very well known in the art as they have provided the dental community with indirect vision during dental procedures for many years. As is well known, the goal of a mouth mirror is to provide vision to the lingual surface of both the maxillary and mandibular arches where direct visibility is difficult if not impossible. Other areas of the mouth are viewed more readily with the assistance of a mouth mirror.
During a dental procedure, the ability of a mouth mirror to provide indirect vision is commonly compromised by several factors. As a result, the mirror is not able to provide the very function for which it was designed. For example, fogging of the mirror is a common problem with dental mirrors, particularly when a dental mirror at room temperature is placed inside a patient's warm, humid mouth. As soon as a patent exhales, condensation can cloud the mirror. If irrigation is required during a procedure, water droplets may build up on the mirrors surface distorting vision. When drilling or removing of existing tooth structures, debris typically collects on the surface of the mirror blocking the dental professional's vision. Unfortunately, these conditions are a part of the dental environment and the mouth mirror is limited in its ability to provide the function it was intended for.
There have been many attempts to address the well-known problem of fogging of dental mirrors during a dental procedure. For example, throughout the procedure, it is common for a dental assistant to constantly use air and water on the mirror to create a clear visual pathway before the dental professional resume use of the mirror.
Further attempts in the prior art to preventing a dental mirror from fogging up include dipping the mirror into a mirror de-fogging solution before insertion into the mouth. The thin film of solution left on the mirrors glass surface thereafter improved visibility for the operator. However, this anti-fog film of solution easily comes off during the course of dental procedure as water, that is constantly being spraying in the mouth, encourages the anti-fog film to come off. As the film degrades, fogging will return necessitating retreatment of the mirror with new anti-fog solution. As can be understood, this is time consuming and disruptive during a dental procedure.
Still further, there have been attempts to deliver air to the face of the mirror using air, and the like. Such delivery of air requires control of the flow of such air. The prior art employs simple valves that are inline with the flow of air to the dental mirror. However, these prior art attempts are inadequate in that they are difficult to use and fail to provide the user with a level of control and customization that is required to make the use of such a device efficient and worthwhile. More specifically, the prior art does not enable the user to ergonomically fine tune the level of the delivery of compressed air to the mirror and also does not provide for an option to deliver a full blast of air and still return back to the previously set custom level of air delivery.
The foregoing attempts in the prior art fail to adequately address the problem of moisture fog and debris accumulation on the surface of a dental mirror during a dental procedure.
In view of the foregoing, there is a demand for a dental mirror that is fog-free during its use during a dental procedure and uses air from an existing compressed air source in a dental office to remove moisture, fog and debris from the surface of the mirror. There is a need for such a dental mirror to be adjustable in air flow, adjustable in mirror position and ergonomic. Moreover there is a demand for a dental mirror that is ergonomic yet enables the user to fine tune the level of the delivery of compressed air to the mirror while also providing for an option to deliver a full blast of air and still return back to the previously set custom level of air delivery.
The present invention preserves the advantages of prior art dental mirrors. In addition, it provides new advantages not found in currently available dental mirrors and overcomes many disadvantages of such currently available dental mirrors.
The fog-free dental mirror of the present invention provides an affordable mouth mirror, which increases the productivity of the dental team while providing consistent, clear vision of the oral cavity. The dental mirror of the present invention uses compressed air directed at and over the surface of the mirror to provide a protective air stream over the surface of the mirror to avoid the accumulation of moisture while keeping debris off of the surface of the dental mirror. The fog-free dental mirror of the present invention employs a new and novel valve construction that unique enables the user to ergonomically control the amount of flow of compressed air delivered to a mirror surface. It enables a fine tuned control of flow while providing an option for a full blast of compressed air when needed. Even if the valve is release, the device maintains the custom set level of compressed air delivery. Moreover, even after a full blast of compressed air, the valve returns to its previously set custom level of compressed air delivery.
The handle of the mirror is preferably aluminum and is ergonomically designed and allows for the novel regulation of airflow and quick connection of multi-positional mirror heads. The new and unique dental mirror is fully auto-clavable.
It is therefore an object of the present invention to provide a dental mirror that is fog-free during its use during a dental procedure.
Another object of the present invention is to provide a dental mirror that uses air to remove moisture from the surface of the mirror.
Yet another object of the invention is to provide a dental mirror that uses air to remove debris from the surface of the mirror.
A further object of the present invention is to provide a dental mirror that is fog-free and auto-clavable.
Another object of the present invention is to provide a dental mirror that has adjustable air flow.
Another object of the present invention is to provide a dental mirror that is ergonomic.
Another object of the present invention is to provide a dental mirror that rotationally adjustable to optimal angle position.
Another object of the present invention is to provide a dental mirror that can provide a single blast of air for moisture and debris removal.
A further object of the present invention is to provide an ergonomically controlled delivery of compressed air to a mirror surface.
Another object of the present invention is to provide a fine tuned control of flow while providing an option for a full blast of compressed air when needed where even if the valve is release, the device maintains the custom set level of compressed air delivery.
Further, another object of the present invention is to provide a dental mirror that, even after a full blast of compressed air, the valve returns to its previously set custom level of compressed air delivery obviating the need for the user to reset the custom level of air delivery.
The novel features which are characteristic of the present invention are set forth in the appended claims. However, the invention's preferred embodiments, together with further objects and attendant advantages, will be best understood by reference to the following detailed description taken in connection with the accompanying drawings in which:
Turning first to
With the handle 12 and mirror stem 14 interconnected, a continuous air supply path 48 is maintained via an aperture 50 in the handle 12 and port 52 in the mirror stem 14. The aperture 50 in the handle 12 can also been seen in detail in
The multi-sided connection interface 38, 40 between the handle 12 the mirror stem 14 and, as a result, the mirror housing 16 itself, enables the direction of the mirrored surface 20, which is angled, to be adjusted relative to the location of the valve assembly 18 for control of the flow of air through the dental mirror 10. This enables the use to place the valve assembly 18 at a number of locations rotationally relative to the face 20 of the mirror to achieve the most comfortable position for efficient use of the device 10. For example, this enables the dental mirror 10 to be easily customized for both right and left handed use.
While it is shown that the handle 12 includes the male side 38 of the interconnection and the mirror stem 14 includes the female seat 40, it should also be understood this configuration can be reversed where in the mirror stem 14 provides a male member and the handle provides the female seat. It should also be noted that a multi-sided configuration interconnection is just one example. Other types of connections, such as those greater than or fewer than twelve sides can be used, such as a hexagon, octagon or square and still be within the scope of the present invention.

As seen in
It should be understood that the slidable interconnection of pins 81 on barrel valve 56 within slots 83 of valve actuator 24 shown are just one example of a slidable interconnection that is envisioned in accordance with the present invention. Other interconnection structures and methods that provide such controlled slidable interconnection between the barrel valve 56 and actuator 24 may be used and are within the scope of the present invention. For example, the interconnection may be reversed where the valve actuator 24 has pins that engage with slots formed in the barrel valve 56 (not shown). Further, such a slidable interconnection need not include pins and slots but may employ a different mating interconnection structure to carry out the same function.
In
If there is a desire to deliver a full blast of air to the reflective mirror surface 20, a direct downward pressure on the valve actuator 24, regardless of the current pivotal position of the actuator 24, causes the bosses 74a, 74b in their respective vertical slots 76 on opposing sides of the handle to travel downwardly against the forces of springs 75 to fully open the barrel valve 56 to a condition as seen in
As to the full blast feature of the present invention, it should be understood that the slidable interconnection of bosses 74a and 74b within their respective slots 76 in the handle, as shown, are just one example of a slidable interconnection that is envisioned in accordance with the present invention to carry out the inventive blast function described above. Other structures and methods that provide such a blast function, by permitting the actuator 24 to slide relative to the handle 12, may be used and are within the scope of the present invention. For example, this interconnection may be reversed where bosses are provided on the handle and respective slots are carried on the actuator 24 (not shown). Further, such a slidable interconnection need not include bosses and slots but may employ a different mating interconnection structure to carry out the same function.
The dental mirror 10 of the present invention is preferably made of material that is durable and suitable for being cleaned and sterilized using an autoclave or the like to permit reuse. For example, the parts and components, such as the handle 12, mirror stem 14 and mirror housing 16 can be made of stainless steel or other similar material. The protective boot 22 can be made of rubber, or the like. For the mirror surface 20 of the mirror, the appropriate coating can be used, which is well known in the art, can be used to provide a reflective surface.
In view of the above, a dental mirror 10 of the present invention has the capability of delivering air flow proximal to the surface 20 of the reflective mirror to effectively remove moisture and debris therefrom for more effective and efficient use of the dental mirror 10 during a dental procedure.
It is also possible that the dental mirror 10 of the present invention be disposable. In that case, it may be desirable to make many parts, such as the handle 12, stem 14 and mirror housing 16, of the dental mirror 10 of the present invention out of less expensive materials, such as plastic.
It would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be covered by the appended claims.
