Description
Absauggerät ür ärztliche oder zahnärztliche Zwecke.Suction device for medical or dental purposes.
Derartige Absauggeräte werden zum Absaugen von Bohrstaub, Khlwasser, Blut und Sekret verwendet. Dabei ist es oft erforderlich, die Saugleistung zu verändern, um sie den Arbeitserfordernissen während der Behandlung anpassen zu können.Such suction devices are used to extract drilling dust, cooling water, Used blood and secretions. It is often necessary to change the suction power, in order to be able to adapt them to the work requirements during the treatment.
Die Änderung der Saugleistung erfolgt bei derzeitigen Geräten durch Verändern des Ansaugquerschnitts der Saugleitung, meist am Griffsttlck oder durch Hinzuschalten eines Beipasses, Uber den an geeigneter Stelle in gleichem Maße mehr Luft angesaugt wird als durch das Saugmundstück weniger, dabei bleibt die Drehzahl des Motors unverändert und es entstehen die bekannten Nachteile, wie Wirbelbildung am Mundstück und damit Geräuscherhöhung, z.T. starke Erwärmung des Motors neben hohem Verbrauch von elektrischer Leistung. Insbesondere die Erhöhung der Geräusche wirkt unangenehm und oft auch beängstigend auf den Patienten.The change in suction power is carried out with current devices Changing the suction cross-section of the suction line, mostly on the handle or through Adding a bypass, about which more at a suitable point in the same measure Air is sucked in less than through the suction nozzle, while the speed remains of the engine unchanged and there are the known disadvantages, such as vortex formation on the mouthpiece and thus increased noise, partly strong heating of the motor next to it high consumption of electrical power. In particular, the increase in noise has an uncomfortable and often frightening effect on the patient.
Der Erfindung liegt die Aufgabe zugrunde, diese, bei der Regelung der Saugleistung des Absauggerätes entstehenden Nachteile zu beseitigen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Drehzahl des Saugmotors entsprechend der gewUnschten Saugleistung verändert wird, und zwar durch Ändern der Speisespannung mittels eines Stelltransformators, eines Schiebewiderstandes oder mittels Phasenanachnittsteuerung z. B. durch einen Triac-Regler. Die Regulierung der Saugleistung kann natürlich stufenlos oder über zweckmäßig eingeteilte Stufen erfolgen. Die Stellorgane zur Drehzahlregulierung können am Handstück, am Gerät oder an einem sonstigen Einrichtungsgegenstand der ärztlichen oder zahnärztlichen Praxis angebracht sein, oder auch parallel an zwei oder mehr verschiedenen Stellen, da es z. B. erforderlich sein kann, daß sowohl der Behandler als auch die Helferin die Saugleistung bzw. Motordrehzahl verändern müssen.The invention is based on the object of regulating this to eliminate the disadvantages arising from the suction power of the suction device. This task is achieved according to the invention in that the speed of the suction motor accordingly the desired suction power is changed by changing the supply voltage by means of a variable transformer, a sliding resistor or by means of phase control z. B. by a triac regulator. The regulation of the suction power can of course be carried out continuously or via appropriately divided levels. The actuators for Speed regulation can be done on the handpiece, on the device or on another piece of furniture the medical or dental practice, or parallel to it two or more different places, as there are e.g. B. may be required that both the practitioner as well as the assistant change the suction power or motor speed have to.
Die mit der Erfindung erzielbaren Vorteile sind Regelung der Saugleistung ohne Querschnittsveränderung der Leitung und damit Verminderung der Geräusche, Anpassung der Motorleistung an die benötigte Saugleistung und bessere Regulieriöglichkeit der Saugleistung.The advantages that can be achieved with the invention are regulation of the suction power without changing the cross-section of the line and thus reducing the noise, adaptation the motor power to the required suction power and better regulation the suction power.
