A dental lighting device arranged such that the light from a light source is reflected by a reflection plate and is cast into the inside of the mouth, wherein a mirror member used to look at the inside the mouth is provided in combination with a lighting device component so that the mirror member can take a mirror use posture where the surface of the mirror member is almost perpendicular to the light beam from the reflection plate at least when the mirror member is used. The mirror member of the lighting device can also take a mirror non-use posture where the mirror surface does not intercept the light beam.

The present invention comprises an improved oral self inspection device that is versatile, inexpensive, and easy to use. The device consists of a small, cylindrical light source on which a small front primary or inspection mirror, a larger rear secondary or ocular mirror, and a cheek and tongue extender are mounted. Each of these implements is mounted at the end of an arm whose other end is rotatably and slideably mounted on the cylindrical light source. Each such arm is independently rotatable a full 360 degrees around the body of the cylindrical light source, such that the relative angular position between each of the implements is infinitely variable. Each of the arms is also independently slideable along the cylindrical light source, such that the relative separation between the implements can also be readily changed. The primary mirror may be attached to its mounting arm at a fixed angle, or the angle of tilt may be adjustable. The secondary mirror is mounted to its arm by means of a universal ball joint such that its angular orientation can be easily changed. The secondary mirror consists of a concave mirror on one side and a flat mirror on the other side to allow both magnified and unmagnified viewing of the image reflected by the primary mirror. The tongue and cheek extender consists of a resilient arm having a flat enlarged portion at one end which can be positioned adjacent the primary mirror such that it maintains a person's cheek or tongue to one side of the primary mirror and a clear line of sight from the secondary mirror to the primary mirror is maintained.

A holder has a first aperture and a second aperture adapted to receive a light source and a wand of a mirror assembly, respectively. The holder positions the light source and the mirror assembly so that light from the light source is received by a mirror of the mirror assembly. Suitable manipulation of the holder enables the mirror assembly to be positioned so that a user can indirectly visualize an object in the presence of light from the light source reflected off the mirror.

An ergonomic non-obstructive illuminated examination mirror for dentistry, medicine and surgery, without the need of fiber optics, includes a slim line elongated member having a wire connection passage, a weighted first proximal end with a battery chamber and a second distal end. A removable disposable non-fogging angled reflective mirror head is coupled to the second end of the elongated member. Light to the mirror is provided by a low heat emitting light source attached to the second end of the rod directed toward the angled reflective head. The power source is connected to the low heat light source by one or more conductive wires within the wire passage and a switch, thereby forming a circuit with the power source and the light source, which is activated by a switch connected to the conductive wire connection.

A convertible laryngoscope includes a deployable integral mirror to allow the doctor to clearly view the larynx and more easily insert an endotracheal tube. In many patients, due to injury, deformation, or an existing medical condition, the introduction of the endotracheal tube can be a prolonged and difficult affair, the doctor being forced to work blind when they cannot gain an unobstructed view of the larynx and the path that the cannula or tube needs to travel during intubation. The present invention addresses this problem by providing the above mentioned mirror, which is disposed in a first position proximate the laryngoscope blade during the initial introduction of the blade into the patient's mouth. Once the base of the tongue is reached and depressed, the user may deploy the mirror into a second position extending towards the soft palate that allows a reflected view towards the larynx and epiglottis. This allows the person intubating the patient to clearly see the path that the cannula needs to take, preventing inadvertent damage to the soft tissue of the mouth and throat. A fixed integral light source is included that is directed towards the deployed mirror position to illuminate the proposed path.
