Abstract

A process for producing otoplastics comprises taking a silicone impression of a patients ear and then using it to produce a plaster mold which is filled with a plastic. The plastic is then polymerized in a microwave apparatus.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Otoplastiken.The invention relates to a method for producing Earmolds.

Bei den bekannten Kunststoffen zur Herstellung von Oto­ plastiken besteht die Gefahr, daß bei dem Benutzer aller­ gische Reaktionen ausgelöst werden und dadurch die Benut­ zung von Hörgeräten mit diesen Otoplastiken sogar unmög­ lich gemacht wird.In the known plastics for the production of Oto plastics there is a risk that the user of all reactions are triggered and thereby the user even hearing aids with these earmolds are impossible is made.

Es ist Aufgabe der Erfindung, ein neuartiges Verfahren zur Verwendung eines Kunststoffs für Otoplastiken zu nen­ nen, bei welchem die Gefahr von allergischen Reaktionen nicht mehr besteht und der weiterhin einfach zu verarbei­ ten ist, eine lange Lebensdauer besitzt und auch mechani­ schen Belastungen gewachsen ist.The object of the invention is a novel method to use a plastic for earmoulds in which there is a risk of allergic reactions no longer exists and is still easy to process ten, has a long service life and is also mechani strain has grown.

Diese Aufgabe wird erfindungsgemäß durch das Verfahren zur Herstellung der Otoplastiken gemäß Anspruch 1 ge­ löst.This object is achieved by the method for the production of the earmolds according to claim 1 ge solves.

Insgesamt soll die Herstellung von Otoplastiken verein­ facht und verbilligt werden, und es soll das Auftreten von allergischen Reaktionen ausgeschlossen werden.Overall, the manufacture of earmolds is said to be united be made cheaper and cheaper, and it should occur be excluded from allergic reactions.

Im einzelnen wird das erfindungsgemäße Verfahren wie folgt durchgeführt:
Der HNO-Arzt bzw. der Hörgeräte-Akustikmeister nimmt einen Silikon-Abdruck von dem betreffenden Patientenohr.In detail, the method according to the invention is carried out as follows:
The ENT doctor or the hearing aid acoustician takes a silicone impression of the patient's ear in question.

Aus der ohrabgewandten (distalen) Fläche des Abdruckes wird mittels eines Skalpells großzügig ein kegelförmiges Stück herausgeschnitten, bzw. mit einem Silikon-Fräser ausgefräst, ohne entscheidende Partien des Abdruckes zu beschädigen. Anschließend wird die Ohrabformung zweimal tauchgewachst und anschließend mit einem Netzmittel be­ handelt.From the distal surface of the impression becomes a conical one with a scalpel Cut out a piece, or with a silicone cutter milled out without decisive parts of the impression to damage. Then the ear impression is taken twice dip-waxed and then coated with a wetting agent acts.

Eine mehrteilige und fest verschließbare mikrowellen­ durchlässige Spezialküvette für dentale Kunststoff-Preß- Verfahren wird geöffnet und mit Vaseline oder Silikon- Spray innenseitig sorgfältig gegen Gips isoliert.A multi-part and firmly lockable microwave permeable special cuvette for dental plastic press Procedure is opened and with petroleum jelly or silicone The inside of the spray is carefully insulated against plaster.

Eine ausreichende Menge Dental-Gips des Klasse-III-Typs wird mittels eines Vakuumrührgerätes angerührt und in den Sockelteil der Küvette gegeben. Der gewachste Ohrab­ druck wird nun vorsichtig von Hand blasenfrei in den weichen Gips gesenkt, wobei die mesiale Gehörgang-Seite zuerst benutzt wird, bis die distale Abschlußkante des Abdrucks das Gipsniveau erreicht. Daraufhin wird der Gips teilweise ausgehärtet und die Gipsoberfläche sorg­ fältig geglättet.A sufficient amount of Class III dental plaster is stirred by means of a vacuum mixer and in given the base part of the cuvette. The waxed ear pressure is now carefully blown by hand into the soft plaster lowered, with the mesial ear canal side is used first until the distal end of the Impression reaches the level of gypsum. Then the Plaster partially hardened and the plaster surface provides wrinkled smooth.

Nach Aushärten des Gipses wird die Oberfläche mit Sili­ kon-Spray benetzt, der obere Küvettenteil aufgesetzt, und die Form wird vollständig mit frisch angerührtem Dental- Gips Klasse-III-Typ aufgefüllt. Darauf wird der Konter­ deckel aufgesetzt, die Küvette fest verschlossen, von außen werden etwaige Gipsüberschüsse gründlich entfernt und der zuvor eingefüllte Gips vollständig ausgehärtet.After the plaster has hardened, the surface is covered with Sili con-spray wetted, the upper part of the cuvette attached, and the form is completely filled with freshly mixed dental Filled plaster of class III type. This is the counterattack put the lid on, the cuvette tightly closed, by any excess gypsum is thoroughly removed from the outside and the previously filled plaster is completely hardened.

Die noch verschlossene Küvette wird in einem Mikrowellen­ gerät ca. 1 Minute mit Mikrowellen von 750 Watt Leistung beschickt. Die Küvette wird geöffnet, und beide Teile wer­ den gipsseitig gründlich mit kochendem Wasser überbrüht. Der Ohrabdruck wird dann vorsichtig aus der Gipsform ge­ hebelt und die Negativform ebenfalls noch einmal gründ­ lich mit heißem Wasser ausgebrüht, um etwaige Wachsreste darin restlos zu entfernen. Die Küvettenhälften kühlen daraufhin einige Minuten ab, und dann werden die gesamten Gipsflächen beider Küvettenteile sorgfältig mit einem Kunststoffisoliermittel behandelt.The still closed cuvette is in a microwave approx. 1 minute with microwaves with a power of 750 watts loaded. The cuvette is opened and both parts are opened  thoroughly scalded with boiling water on the plaster side. The earprint is then carefully removed from the plaster mold pry and found the negative form again Lich scalded with hot water to remove any wax residue to remove it completely. Cool the cell halves then a few minutes and then the whole Plaster surfaces of both cell parts carefully with one Plastic insulation treated.

Die Negativform des Ohrabdruckes wird mit dem gewünsch­ ten Kunststoff gefüllt.The negative form of the ear print is made with the desired one filled with plastic.

Bei Verwendung von SHERAMET-MW-2000-Kunststoffen werden die Bestandteile in leicht zähflüssiger Konsistenz ange­ mischt und blasenfrei langsam in die Negativform gegos­ sen, bis das Niveau bündig mit der Gipsfläche ist. Die Kunststoff-Melange ruht offen mindestens 5 Minuten, und dann wird der obere Küvetten-Konter aufgesetzt.When using SHERAMET-MW-2000 plastics the ingredients in slightly viscous consistency mixes and slowly bubble-free poured into the negative mold until the level is flush with the plaster surface. The Plastic melange is left open for at least 5 minutes, and then the upper cuvette counter is attached.

Bei Verwendung von DENTSPLY-DeTrey-Microbase-Kunststoff wird ein Luftabzugskanal von ca. 3 mm Durchmesser schräg in den Gips neben die Negativform des Ohrabdruckes ge­ bohrt, so daß der Abzugskanal die mesiale Spitze der Ge­ hörgangsform öffnet.When using DENTSPLY DeTrey Microbase plastic an air outlet duct with a diameter of approx. 3 mm is inclined in the plaster next to the negative form of the earprint drills so that the drainage channel is the mesial tip of the Ge ear canal shape opens.

Die Microbase-Paste wird kräftig und schlierenfrei in die Ohrform geknetet, bis der Kunststoffteig wieder aus dem Luftabzugskanal tritt. Überschüsse werden entfernt und der obere Küvetten-Konter aufgesetzt.The microbase paste becomes strong and streak-free kneaded the ear shape until the plastic batter comes out again the ventilation duct. Surpluses are removed and the upper cell counter is attached.

Unter einer Hydraulik-Presse für dentale Anwendungen wer­ den die Küvettenteile unter langsam ansteigendem Druck bis zu einem Enddruck von 100 Kp/cm2 gepreßt. Der End­ druck wird ca. 1 Minute gehalten, die Küvette der Presse entnommen, der überschüssige Kunststoff-Preßfahnen ent­ fernt und die Küvette fest endverschlossen. Der Kunst­ stoff in der Küvette wird in dem Mikrowellengerät ca. 4 Minuten bei 750 Watt Leistung polymerisiert.Under a hydraulic press for dental applications, the cuvette parts are pressed under slowly increasing pressure up to a final pressure of 100 Kp / cm 2 . The final pressure is held for approx. 1 minute, the cuvette is removed from the press, the excess plastic plugs are removed and the cuvette is firmly closed. The plastic in the cuvette is polymerized in the microwave oven for approx. 4 minutes at 750 watts.

Nach abgeschlossener Polymerisation wird die Küvette dem Mikrowellengerät entnommen und ca. 2 Stunden an der Raum­ luft abgekühlt, wobei gegebenenfalls, je nach Größe der Küvette, diese anschließend noch für ½ bis 1 Stunde in ein Kaltwasserbad gelegt wird. Danach wird die Küvette geöffnet und der in Gips gefaßte Kunststoff-Rohling aus­ gebettet.After the polymerization is complete, the cuvette is removed Microwave oven removed and about 2 hours in the room air cooled, where appropriate, depending on the size of the Cuvette, this then for ½ to 1 hour in a cold water bath is placed. Then the cuvette opened and the plastered plastic blank from bedded.

Zuletzt erfolgt die Bearbeitung des Rohlings nach den Re­ geln zur Herstellung von Kunststoff-Otoplastiken in der Hörgeräte-Akustik.Finally, the blank is processed according to the Re apply to the manufacture of plastic earmolds in the Hearing aid acoustics.
