Abstract

The invention concerns a portable integrated and very compact light for fastening to a speculum, which comprises a cold light source (1), a tube (3), a power source (12, 13), a housing (8), a housing cover (14) and, as an import element, fastening means (6) for fastening to a speculum.

Description


  Portable, integrated light for attachment to a speculum

The present invention relates to a portable, integrated light for attachment to a speculum according to the preamble of patent claim 1.

The illumination of the body cavity is an important requirement for the successful use of a speculum. Existing devices use as light source bulbs, which have relatively low light power. Namely, if the light power is increased so that it is sufficient for the illumination of the body cavities, this leads to an undue heating in the examined tissue.

Known light devices use as light source light emitting diodes (LED). These are e.g. connected to a power source over a longer connection.

   This is disadvantageous, as one has a cable in the work area for a normal examination, which must be respected. In many cases, a light-emitting diode (LED) is integrated in the medical instrument. There is no light for examination of the body cavity unless the medical instrument is used.

One of the unsolved problems of existing bulbs not associated with the speculum is their attachment to the speculum. It is often cumbersome and expensive. The two devices are e.g. bolted, or connected by Velcro. While a hook-and-loop fastener does not provide sufficient secure grip and is a concern for sterility, mounting with screws requires preparation time. Other versions are integrated as part of the speculum.

   This increases the cost of the speculum and presents problems with hygiene.

Of course, in the practice room bulbs such as ceiling lamps, floor lamps, etc. with separate strong light sources are connected to the mains. However, these are bulky lights that can only be used locally. In addition, the optimal alignment of the light on the body cavity to be examined under difficult anatomical conditions is not satisfactorily possible.

The present invention now has the task of producing a light source, quickly and safely to a normal speculum as it is commonly used in gynecology and obstetrics, but also in veterinary medicine, can be mounted. This bulb should be robust against heavy bumps and take up little space.

   Typically, the gynecologist or veterinarian has his speculum with him and if necessary, the small bulbs on his commonly used speculum with little effort and easy fix. This light source should have great light power, do not heat the tissue by heat development and shine even in deep body cavities precisely in the direction to be examined.

This object is achieved by a portable, integrated light for attachment to a speculum with the features of claim 1.

   Further inventive features will become apparent from the dependent claims and the advantages thereof are explained in the following description.

Content of the invention is an integrated, portable lamp that has neither a light guide with a long connection nor a light bulb with warming effect, but uses a white light emitting (high-performance) light emitting diode (LED). Lamp and power source are in the same housing. It is also quite conceivable that the light intensity can be adjusted by a control device. Also, such a control device can be accommodated without problems in the same housing.

   It is ideal if the luminaire can be easily and quickly, e.g. can be fixed by means of compression spring and slide to the handle already existing, common and reusable specula.

For the light, it is of great importance that there are no openings, gaps and niches, which allow contamination by blood and other body fluids. For this reason, all items are integrated in a housing, which is cleanly sealed in the lamp according to the invention. The luminaire must be cleaned with commercially available disinfectants or placed in a disinfectant bath. If, after use, the removal of the illuminant is forgotten inadvertently and the speculum, together with the luminous device for sterilization, is placed in the sterilizer, a stopper prevents the luminaire from exploding.

   To avoid this dysfunction as possible, the luminaire is made of colored luminous metal, e.g. made of anodized aluminum.

The lamp must be small and handy so that it can be carried in the pants bag. The impact resistance is designed so that it easily withstands falls on the ground. The integrated and fixed to the holder handle of the speculum small lamp does not interfere with the work area of the doctor and provides direct light into the body cavity.

   Disturbing shadows fall away and the overview becomes optimal.

In the drawing shows:

Fig. 1 exploded view of the lamp

[0014] FIG. 2 overall view of the luminaire

Fig 3 attached light on the speculum

Fig 4 attached light on the speculum

The figures represent preferred execution proposals, which are explained in the following description as examples.

The lamp (Fig 1) consists essentially of a cold light source 1, which is connected by a pipe 3 to the housing 8. In the tube 3 is a resistor 2. In the housing 8 in which the tube 3 is embedded, is closed by a housing cover 14. In the space formed by the housing 8 and housing cover 14 is a battery compartment 12 are housed in the battery 13.

   The battery compartment 12 forms with the batteries 13, the power source 12,13. The power source 12,13 the housing cover 14 opposite to the housing 8, a fastening means 6 is arranged.

In Fig 2 shows how compact the lamp is built. The housing cover 14 is connected to the housing 8 with a thread. An O-ring 9 between these parts seals the interior. The resulting gaps between the housing 8 and the housing cover 14 are closed by suitable means in such a way that no contamination by blood or other humors can occur. The two batteries 13 are held by a compression spring 15. The conductor piece 11 transmits the contact of one pole of the batteries 13 via an electric cable and a resistor 2 to the cold light source first

   The other pole is led by the batteries 13 through a cable clamping ring 10 and the corresponding wire connection through tube 3 to the cold light source 1. The tube 3 is held in the housing 8 by a clamping screw 4.

The fastening means 6 is fastened by means of screw 5 on the housing 8. Between fastening means 6 and housing 8, a pad 7 is arranged. The fastener is adapted to easily and quickly attach the luminaire to a speculum 20. FIG. 3 and FIG. 4. A simple resilient clip made of metal or plastic serves, as shown in FIG. 4, to clamp the luminaire on the speculum 20.

As a cold light source 1, a light-emitting diode "LED" is used with white light, which gives no heat to the tissue to be examined.

   On the other hand, the light source should illuminate the body cavity brightly, so that for the investigation with sufficient light, it is also guaranteed to see what you are investigating.

Thus, the light for sterilization and cleaning is not left on the metal speculum 20, the tube 3, the housing 8 and the housing cover 14 is marked with color. An elegant way for this marking is the use of anodized aluminum for these parts. The tube 3 can be made flexible, so that the direction of the cold light source 1 can be additionally adjusted. However, this is not necessary for the daily use of the lamp.
