Description

Bei der vorligenden Erfindung handelt es sich um einen Ohrstöpsel aus Stein zum Einführen in den menschlichen äußeren Gehörgang zum Schutz gegen Lärm und um die Vorrichtung zur Befestigung einer Lasersonde zur Messung der dreidimensionalen Daten des Gehörgangs zur Herstellung des Ohrstöpsels durch einen automatischen Fräser.In the present invention acts it is an earplug made of stone for insertion in the human outer ear canal Protection against noise and around the device for attaching a laser probe for measurement the three-dimensional data of the ear canal to produce the earplug through an automatic router.

Als Lärmsschutz sind bereits viele Varianten von Ohrstöpseln, z.B. aus Kunststoff bekannt ( DE941165U1 , DE9112815U1 ; DE9302783.4 , DE9313061U1 ). Der Nachteil der herkömmlichen Ohrstöpseln ist, das sie oft nach mehrmaliger Benutzung entweder durch Formveränderung keinen Lärmschutz mehr bieten und in der Regel kurzlebig sind, oder durch Schmutz zur Entzündung des Gehörgangs führen.Many variants of earplugs, e.g. made of plastic, are already known as noise protection ( DE941165U1 . DE9112815U1 ; DE9302783.4 . DE9313061U1 ). The disadvantage of conventional earplugs is that, after repeated use, they either no longer offer noise protection by changing their shape and are usually short-lived, or they cause inflammation of the ear canal due to dirt.

Ein Ohrstöpsel aus Mineralstein hat den Vorteil, dass durch die relativ hohe Dichte und den geringen Absorptionskoeffizienten (ca. 0.02) ein sehr hoher Lärmschutz gewährleistet ist. Außerdem ist die Gefahr von Allergien insgesamt gering. Der Ohrstöpsel ist einfach zu pflegen und ist und kann durch seine Stabilität wesentlich länger getragen werden als die bekannten Ohrstöpsfel. Um die o.g. Eigenschaften zu erfüllen sollte der Mineralstein eine Härte ab 5 auf der Mohsskala besitzen. A mineral stone earplug has that The advantage is that the relatively high density and the low absorption coefficient (approx. 0.02) very high noise protection guaranteed is. Moreover the risk of allergies is low overall. The earplug is easy to maintain and is essential due to its stability longer are worn as the well-known earplugs. To the above characteristics to fulfill the mineral stone should be a hardness from 5 on the Mohsskale.

Damit das harte Material im äußeren Gehörgang trotzdem als angenehm empfunden wird muß die Form genau an den Gehörgang angepasst sein. Dazu müssen die Maße des Gehörgangs bis zu einer Tiefe von ca. 1,5 cm gemessen und aus diesen Daten der Stein entsprechend gefräst werden.So that the hard material in the outer ear canal anyway is perceived as pleasant Shape exactly to the ear canal be adjusted. To do this the dimensions of the ear canal measured to a depth of approx. 1.5 cm and from this data the Stone milled accordingly become.

Das heraus meißeln eines solchen Ohrstöpsels per Hand ist nahezu unmöglich. Die Erfindung benutzt die bekannte Prototyping-Technik, die bereits bei der automatischen Herstellung von Zahn-Inlays durch Roboter in der Zahnarztpraxis verwendet wird (CEREC III).Chisel out such an earplug by Hand is almost impossible. The invention uses the well-known prototyping technique, which is already at the automatic production of tooth inlays by robots in the Dental practice is used (CEREC III).

Hierzu können durch eine Lasersonde, die in den Gehörgang eingeführt wird, die dreidimensionalen Daten des Gehörgangs gesammelt und über einen Rechner zum automatischen Fräser übertragen werden. Aus einem Stück Stein kann so ein maßgeschneiderter Ohrstöpsel hergestellt werden.For this, a laser probe, the in the ear canal introduced the three-dimensional data of the ear canal is collected and transmitted via a Computer to be transferred to the automatic router. Out of one piece Stein can be such a tailor-made ear plug getting produced.

Um die Lasersonde ohne Verletzung der Gehörgangshaut einzuführen sieht die Erfindung ein Führungsrohrror (1C), in das die Sonde platziert wird, welches durch einen auf dem Kopf fixierten Ring (1A) über drei Gelenke (1B) in Höhe des Gehörgangs gebracht werden kann. Natürlich muß der Gehörgang mit einem Ohrmikroskop (wie bei der HNO-Einheit) betrachtet werden, nachdem durch einen Ohrtrichter der Gehörgang dargestellt wird. Anders als beim üblichen Ohrtrichter sieht die Erfindung einen Ohrtrichter mit einem länglichen Spalt vor, damit nach Einstellung der Sonde, der Ohrtrichter heraus genommen werden kann ohne die Sonde zu bewegen.In order to insert the laser probe without damaging the ear canal skin, the invention provides a guide tube 1C ), in which the probe is placed, which is attached to the head by a ring ( 1A ) over three joints ( 1B ) can be brought up to the level of the ear canal. Of course, the ear canal must be viewed with an ear microscope (as with the ENT unit) after the ear canal is shown through an ear funnel. In contrast to the conventional ear speculum, the invention provides an ear speculum with an elongated gap so that after setting the probe, the ear speculum can be removed without moving the probe.

Das weitere Procedere der Lasermessung und Datenverarbeitung und Übertragung der Daten auf einen automatischen Fräser ist ähnlich der o.g. Technik der Herstellung von Zahn-Inlays.The further procedure of laser measurement and Data processing and transmission the data on an automatic router is similar to the above Technology of Manufacture of dental inlays.
