Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a diagnostic lamp for, for example, examining teeth, which excites a luminous substance applied to body parts to be examined, such as teeth and gums.

To make normally invisible spots, i.e. deposits consisting mainly of bacteria and causing diseases of the teeth and gums, visible by applying a crab-light solution to the teeth and exciting it with a suitable crab-light producing lamp. is publicly known. In this case, it is preferable that the crab-lighting substance adheres only to spots and not to clean and healthy teeth and gums. This also applies to areas where spots have become mineralized and tartar has formed, or where cavities are already present. Only tooth positions that are likely to be affected by the disease or have already been affected will emit a ray of light under illumination, and can be clearly distinguished from other areas that do not emit a ray of light. It is possible to recognize and determine the location. Diseased gums, skin, or tissue can be visualized using the honeydew effect.

Inspection lamps useful for the above purpose include an incandescent lamp as the light source, a dichroic reflector placed behind the lamp, a dichroic filter placed in front of the lamp, and preferably a dichroic filter having the same transmission and reflection properties as the filter. Equipped with a chromatic observation reflector.

. In order for the purpose to be achieved, the light beam illuminating the location to be inspected must be largely limited to blue light, which in particular excites the crab light solution, and as limited as possible with a wavelength corresponding to the color of the yellow or green halo light beam. Must. That is, only under such conditions can a clear contrast be obtained between the crab-light castle and the surrounding non-crab-light castle. Otherwise, when illuminated, the surrounding areas that do not emit crab light will appear to have almost the same color as the crab light rays. This known inspection lamp is expensive to manufacture and therefore expensive to obtain, and is complicated to handle. Furthermore, the user must have constant access to the halo substance, often the honeydew liquid, which is essential to the lamp's use. The known test lamps therefore do not meet the favorable conditions for the widespread use of diagnostic lamps of this type so as to allow regular self-tests. The object of the present invention is that it is simple in structure, can be mass-produced at low cost, is easy for the user to operate, does not require special skill, and is therefore problem-free to use, and is widely used, for example, in the prevention of tooth decay through regular self-examination. The object of the present invention is to provide a diagnostic lamp that can be popularized.

In the present invention, there is provided a diagnostic lamp used for optical excitation of a optical material applied to an object to be inspected, comprising:
The diagnostic lamp includes a housing having dimensions for easy and convenient handling by a user, and on the exterior of the housing a reflector movable between a folded rest position and an open operating position. a mirror pivotally mounted, a light source mounted to the housing, a power source disposed to power the light source, a dispenser for the crab light material, and a light source replaceably mounted to the housing. A diagnostic lamp is provided, comprising means for attaching the dispenser to the housing.

In the light of experience, it has been found that the diagnostic lamp of the present invention has a size of, for example, approximately 12 cm x 5.
5c x 2.5 cm, the wavelength is shorter than the crab light beam to be excited, it contains no or almost no color in the spectral band of this crab light beam, and therefore the excited crab light and the surrounding part that does not emit crab light. It has been found that a simple inexpensive flashlight of the above construction that produces a clear contrast is sufficient.

Equip the flashlight with an ordinary incandescent lamp with sufficient light intensity and a filter adapted to the type of photoluminescent substance used, so that the spectral excitation beam is mostly transmitted, but the spectral band of the crab-light beam itself is sufficiently absorbed. It is particularly preferable to Therefore,
When using, for example, fluorescein that emits green light as the honeydew solution, a filter that absorbs green light and transmits blue light may be used. When using eosin as the crab light solution, the filter must transmit most of the excitatory green light and absorb the yellow and clear bands of the crab light beam. An appropriately colored light bulb itself may also serve as a filter. Using a filter, the light source may consist of at least one light emitting diode called an LED. A preferred embodiment of the present invention is provided with two loading bodies that can be loaded from both open end faces of the outer cover and locked with a locking member, and one loading body is a replaceable dispenser. and the other loading body houses all the electrical components including the battery, light source and lamp switch.

A mirror that cooperates with a switch is attached to the inside of the lid, which can be turned open, so that when the lid is closed, power is cut off to the light bulb, and when the lid is opened, power is automatically supplied. The dispenser preferably consists of a movable plastic container and is provided with an outlet connecting piece having a dispensing nozzle attached thereto, which in the folded position closes the connecting piece and in the outwardly pivoted position. Align with the connecting piece. Liquid can be easily expelled from the dispensing nozzle by squeezing an externally accessible dispenser wall section. The invention will now be described in detail according to three embodiments with reference to the accompanying drawings.

The flashlight shown comprises an elongated housing 1 which is juxtaposed to one another and separated by an intermediate wall 4 and each contains a longitudinally extending hollow chamber 2 and 3.

The hollow chamber 2 houses two batteries 5 connected in series, the front end of which is delimited by a socket 6 provided in the envelope, in which a light bulb 7 is held. A filter 8 is provided in front of the light bulb 7. The other hollow chamber 3 of the flashlight envelope contains a tubular or tubular dispenser 9 with a crab light solution.

The dispenser 9 has a central dip tube 10 which protrudes from the front side of the housing 1 and is closed at its front end by an elastic compression knob 11 formed as an elastically crushable bellows. dip tube 1
A hole 12 that is closed by a valve ball 13 is provided on the inner end surface of the valve. This diff in the vicinity of this hole 12. A discharge nozzle 14 branches from the peripheral wall of the tube 10, penetrates the wall of the dispenser 9, protrudes from the outer body 1, and has a spring-loaded discharge valve 15 installed therein, and this nozzle opens backwards. . That is, the crab light solution is released on the opposite side of the flashlight from the bulb. Therefore, when the user presses the elastic compression knob 11, the valve ball 13 closes the hole 12 of the dip pipe 10, and the discharge valve 15 is opened against the action of its closing spring, causing the liquid in the dip pipe 10 to be opened. is extruded from the discharge nozzle 14. The discharge nozzle 14 on the rear side of the flashlight housing 1 can be directed towards or close to the tooth to be examined. When the compression bottle knob 11 is released, it inflates again due to its self-elasticity, the valve ball 13 is pulled out from the hole 12 by suction, and an appropriate amount of liquid is sucked into the dip pipe 10. A protrusion on the inner wall of the dip pipe 10 formed in front of the discharge nozzle 14 limits the opening stroke of the valve ball 13. Cover caps 16 and 17 close off the two cavities 2 and 3 on the rear side of the housing 1 and are pivoted to the housing 1 in a freely releasable manner, as shown in FIG. 1, or are fitted with screws or click stops. It can be attached and detached via.

The discharge nozzle 14 is elongated and opens on the rear side of the outer body so that it can be easily taken out from the outer shell 1 by opening or removing the cover cap 17 and further removing the elastic compression drop knob 11 of the dispenser 10. Preferably, it protrudes from the slot. With this configuration, an empty dispenser can be easily replaced with a filled dispenser. The front end wall defining the cavity 3 may be omitted so that the dispenser 9 can be replaced without removing the elastic compression knob 11. As is clear from FIGS. 2 and 3, a reflector 19 on the outside of the envelope 1 can be pivoted from the folded position of FIG. 2 to the working position of FIG.
is pivotally connected via a hinge 18, and by shining a beam of light from a diagnostic lamp on it, you can observe your own teeth through this reflector. The folded inactive position and the pivoted operative position of the reflector 19 are preferably in a resting position or in a pre-sprung position. In order to fine-tune the reflecting mirror, the reflecting mirror may be rotatably attached to the outer shell as the case requires, so that it can be rotated around a maricenter in a direction orthogonal to the hinge axis. The optical filter 8 absorbs a wide spectral band of the excitation light beam, transmits the short wavelengths necessary for the crab light excitation, and is adapted to the crab photosensitive solution used.

The embodiment of the diagnostic lamp illustrated in FIGS. 4-12 includes a generally rectangular parallelepiped, fan-flat outer shell 20, which allows the flashlight to be secured, for example, in a breast pocket of a jacket, like a pen. An elastic fixing clip 21 is provided on the back side.

The narrow side walls of the outer shell are rounded, as can be seen in Figures 6 and 8, which show the opposite end walls of the flashlight. A lid 22 that matches the shape of the outer shell, but covers only about half of the outer shell, is pivotally attached to the wide side surface of the outer shell, which is the upper side in the figure, via a hinge 23. The light bulb 24 is mounted on one rounded side wall so as to be offset from the center line so that it is at least partially covered by the lid when the lid 21 is closed, as shown in FIG. As shown in FIGS. 9 and 12, a reflective mirror 25 is fixed inside the lid, and when the lid 22 is opened, this reflective mirror is located behind and slightly above the light bulb 24, and when the user shines the light on the teeth. It is designed to allow easy self-diagnosis. Hishi 22 is designed so that the flashlight is powered at the same time as the lid is closed, and the power is cut off when the lid is opened.

The easiest way to satisfy this condition is, for example, with a push plow switch-like spring, which is disengaged when the lid is opened and assumes the conductive position under the action of the spring, and is held in the disconnected position when the lid is closed. A power on/off switch may be provided. Preferably, the lid 22 is held in the closed condition by a suitable lock or strong protrusion. An outer cover loading body 26 which can be easily taken out by opening the lid 22 is disposed inside the outer cover 20, and a battery and a replacement dispenser for the light-emitting solution are housed in this loading body.

In the illustrated embodiment, this dispenser consists of a known cartridge with a head 2 in which a drip hole is provided.
7, and a part of the wall is flexibly constructed so that dripping can be performed by pushing this movable castle. Outer cover 2
A rinsing piece 28 that can be reciprocated when operating the dispenser cartridge is arranged on the narrow side wall opposite to the light bulb 24 of the 0, and is arranged in parallel with the lid 22 on the end wall of the outer cover 20 adjacent to this. As shown in FIG. 6, there is formed a hole 29 through which the head 27 of the dispenser cartridge can protrude. The sliding piece 28 is provided with a stopper that protrudes into the interior of the housing and surrounds, for example, the inner part of the dispenser head 27, with one end being a trimmed inner surface with the hole 29 of the housing 20 and the other end being the original part of the cartridge. The rear wall or bottom wall of the dispenser mountain cartridge is brought into contact with the stopper piece under the action of a spring supported by the front wall of the storage chamber.

When the sliding piece 28 is moved in the direction of the arrow in FIG. 7 to the position shown in FIG.
8 is driven in the same direction against the spring action, so that the dispensing head 27 protrudes from the hole 29, as shown in FIG. 11, and at the same time,
As the spring pressure increases, the flexible area of the cartridge wall is compressed, and a droplet 30 emerges from the dispenser head 27, as shown schematically in FIG. The tooth and gum area to be examined can be easily wetted with the droplets prior to the examination. When the sliding piece is released, the dispenser cartridge, and therefore the sliding piece, returns to its original position again, and the compressed cartridge wall section returns to its original state.
If the sliding piece 28 is operated again, the droplet will appear. In this embodiment as well, a suitable filter is provided in front of the light bulb 24, or the light bulb itself is appropriately colored. The diagnostic lamp embodiment shown in FIGS. 13 to 20 has a fixing clip 41 (

A fixing plate 65a of a locking portion 65 (FIG. 13) is attached to the rear wall portion 45b of the loading body 45 adjacent to the light bulb 52 between both projecting ends of this wall portion. The locking portion 65 is a flexible region 6 with low wall strength.
It is connected to the fixed plate 65a via 5b, and is bent at right angles to the fixed plate 65a in this transitional position. A circular protrusion 45c formed on the wall portion 45b is fitted with iron into a corresponding notch in the fixing plate 65a to perform a centering function.
On the upper side of the locking portion 65, a protrusion 66 that can be accessed by opening the lid 42 and a protrusion 67 that acts as a fishing rod are formed. The body 45 is locked to the iron edge 40a of the outer cover 40. To remove the loading body 45 together with the battery 48 and the lamp socket 51 with the light bulb 52 attached,
It is only necessary to gently push the protrusion 66 to cause the locking portion 65 to elastically bend inward until the protrusion 67 can be slid under the European green 40a. In the illustrated embodiment, the loader 45 accommodates three batteries 48 (FIG. 14), which are held in electrical series connection with the elastic tongue 54a via a conductor 54 in a known manner. There is.

In FIG. 14, the right pole of the upper battery 48 is a bush piece consisting of a strip 49a that extends almost along the battery and a portion 49b whose inner end is bent at right angles, as shown in FIGS. 17 and 18. I am in contact with 49. This portion 49b, which is provided in the vicinity of the hinge 43 so as to widen toward the lid 42, is provided with a hole 49c and constitutes a spring contact 71 at its free end. The part of the spring contact 71 that is remote from the hinge 43 and closer to the lid 42 is curved into a spherical shape (Fig. 15).
. Occupying a position mirror image of this curved portion of the spring whisker point 71 is the spring contact 7 formed at one end of the other bag piece 50.
0 is also a spherical curved part. The shape of this saddle piece 50 is as shown in FIGS. 19 and 20, and includes portions 50a and 50b forming an angle with each other, the portion 50a constituting the spring contact 70 is provided with a hole 50c, and the other portion 50b

The dispenser storage portion may be connected via a. The lid may be configured to extend over the entire length of the housing, and the battery and dispenser may be loaded directly into the housing after opening the lid. In the present invention, the filter can be omitted by using a light source whose emitted light has a narrow wavelength band close to monochromatic light.

Suitable examples of such light sources include special light emitting diodes, which have recently been used for displays in electrical devices such as small computers and small electronic watches. Diodes of this type can be operated with very low supply voltages, for example on the order of 2 volts, and very low currents on the order of 10-2 amperes, and can be accommodated in small spaces. For example, 2 to 4 light emitting diodes can be used to obtain the required amount of light.
They can be installed in parallel. Since various light emitting diodes with different light colors are commercially available, by selecting the light color, the light source used in the diagnostic lamp of the present invention can be adapted to the excitation characteristics or excitation light rays of various light substances. can. Depending on the crab light solution used, for example, three green light emitting diodes can constitute a light source with a sufficient amount of light.
