Description
Zur Beobachtung und Untersuchung von Kehlkopfschwingungen werden Lichtblitz-Stroboskope verwendet, deren Lichtquelle entweder starr mit den übrigen zum Betrieb benötigten Einheiten in einem Gehäuse vereinigt sind, so daß das gesamte Stroboskop bei Kehlkopfuntersuchungen in eine zweckentsprechende Stellung zu bringen ist, oder die Blitzlampe ist separat als Handlampe in einem Reflektor angeordnet und strahlt so von außen in die Mundhöhle. To be used for observation and investigation of larynx vibrations Light flash stroboscopes are used whose light source is either rigid with the rest Units required for operation are combined in one housing, so that the whole Bring the stroboscope into an appropriate position during larynx examinations is, or the flash lamp is arranged separately as a hand lamp in a reflector and thus radiates from the outside into the oral cavity.
Die geschilderte Art der Beleuchtung ist sehr nachteilig, da die Lichtquelle stets in einem gewissen Abstand zur Mundhöhle angeordnet ist, so daß sich sehr oft eine schlechte Beleuchtung und damit ein umständliches Arbeiten ergibt. Die nicht ausreichende Beleuchtung kann an sich durch Blitzlampen größerer Helligkeit behoben werden. Diese bedingen jedoch einerseits ~einen größeren techn,isdhen Aufwand, andererseits sind sie teurer, und die Unhandlichkeit der Apparatur bleibt trotzdem bestehen. The type of lighting described is very disadvantageous because the Light source is always arranged at a certain distance from the oral cavity, so that Very often there is poor lighting and therefore cumbersome work. The insufficient lighting can be caused by flash lamps of greater brightness be resolved. On the one hand, however, these require a greater technical effort, on the other hand, they are more expensive, and the awkwardness of the equipment still remains exist.
Durch die Erfindung werden die geschilderten Nachteile vermieden, außerdem wird erreicht. daß die Helligkeit der bisher verwendeten Blitzlampen herabgesetzt werden kann, was in technischer und wirtschaftlicher Hinsicht vorteilhaft ist. The described disadvantages are avoided by the invention, also is achieved. that the brightness of the flash lamps previously used is reduced can be, which is advantageous from a technical and economic point of view.
Die Erfindung bezieht sich auf ein Lichtblitz-Stroboskop zur Beobachtung und Untersuchung von Kehlkopfschwingungen. Erfindungsgemäß ist die Blitzlampe in einem als Sonde ausgebildeten Gehäuse angeordnet, welches in den Mundhohlraum eingeführt wird. Vorzugsweise ist die Blitzlampe an einem Ende eines im Querschnitt kreisförmigen Gehäuses angeordnet, das außerdem den Zündtransformator enthält. Zur Vereinfachung der Untersuchungen ist in dem Gehäuse ein die Kehlkopfschwingungen aufnehmendes Mikrophon angeordnet. Vom anderen Ende des Gehäuses wird dem Zündtransformator iiber einen außerhalb der Sonde liegenden Generator die Impulsspannung zugeführt. Um eine gute Beobachtung zu ermöglichen, ist am Umfang der Sonde eine Halterung für einen abnehmbaren Spiegel angeordnet, der in seiner Stellung veränderbar ist. Zweckmäßig ist die Halterung elastisch ausgebildet. Eine besonders einfache Ausbildung der Sonde wird durch Umgießen der Blitzlampe und des Zündtransformators mittels eines härtbaren Gießharzes erreicht. The invention relates to a light flash stroboscope for observation and study of larynx vibrations. According to the invention, the flash lamp is in a housing designed as a probe, which is inserted into the oral cavity will. Preferably, the flashlamp is at one end circular in cross-section Housing arranged, which also contains the ignition transformer. For simplification of the examinations there is a larynx vibrations in the housing Microphone arranged. The ignition transformer is passed from the other end of the housing The pulse voltage is fed to a generator located outside the probe. To a To enable good observation, there is a bracket for one on the perimeter of the probe arranged removable mirror, which is changeable in its position. Appropriate the bracket is designed to be elastic. A particularly simple training of the The flashlamp and the ignition transformer are cast around the probe by means of a hardenable casting resin achieved.
An Hand eines in der Figur dargestellten schematischen Ausführungsbeispiels wird der Erfindungsgegenstand näher erläutert. Die Blitzlampe I ist in einem etwa fingerdicken Gehäuse 2 angeordnet, welches auch den Impulstransformator 3 und ein nicht dargestelltes Mikrophon enthält. Das eine Ende des Gehäuses ist durch eine Linse 4 abgeschlossen. Dem anderen Ende 5 werden die benötigten Spannungen über ein Kabel 6 zugeführt. On the basis of a schematic embodiment shown in the figure the subject of the invention is explained in more detail. The flashlight I is about Finger-thick housing 2 arranged, which also includes the pulse transformer 3 and a Includes microphone not shown. One end of the housing is through a Lens 4 completed. The required voltages are applied to the other end 5 a cable 6 is supplied.
Am Umfang des Gehäuses ist ein abnehmbarer und veränderbarer Halter 7 mit Spiegel 8 angeordnet.There is a removable and changeable holder on the circumference of the housing 7 arranged with mirror 8.
Der Halter ist elastisch ausgeführt, so daß der Spiegel in der Mundhöhle die gewünschte Stellung einnehmen kann.The holder is made elastic, so that the mirror in the oral cavity can take the desired position.
Auf Grund der kleinen Abmessungen wird bei Einführung der Sonde in den Mundhohlraum die Beobachtung und Untersuchung des Kehlkopfes von außen in keiner Weise behindert. Eine weitere Verringerung der Abmessungen der Sonde wird erreicht, wenn diese als Gießharzkörper ausgeführt wird. Due to its small dimensions, when the probe is inserted into the oral cavity the observation and examination of the larynx from the outside in none Way handicapped. A further reduction in the dimensions of the probe is achieved, if this is designed as a cast resin body.
