Abstract
Description
Die Patentanmeldung stellt eine Zusatzpatentanmeldung gemäß § 16(2) Patentgesetz zur anhängigen Patentanmeldung
Die Erfindung betrifft eine verbesserte Vorrichtung zur Erzeugung eines nichtthermischen Plasmas gemäß Patentanmeldung
Ein weiterer Gegenstand der Erfindung besteht darin, wie in
Der Stand der Technik entspricht dem der Patentanmeldung
In diesem Plasma werden insbesondere reaktive Spezies (Radikale) und Strahlung (VUV/UV) erzeugt, die wichtig für den Behandlungseffekt sind. Zum anderen wird das Plasma durch Verlustprozesse aufgeheizt und die Temperatur in der Spitze beträgt etwa 50°C, was unter Plasmabedingungen als „kalt” zu betrachten ist. Bei Anwendungen auf der menschlichen Haut führt jedoch die permanente lokale Behandlung der Haut mit einem Plasma dieser Temperatur zu einer lokalen Verbrennung. Zur Vermeidung derartiger Verbrennungen wird derzeit das Plasma mit einer gewissen Geschwindigkeit über die zu behandelnde Stelle bewegt.In particular, reactive species (radicals) and radiation (VUV / UV) are generated in this plasma, which are important for the treatment effect. On the other hand, the plasma is heated by loss processes and the temperature in the tip is about 50 ° C, which is considered to be "cold" under plasma conditions. However, in human skin applications, permanent topical treatment of the skin with a plasma of this temperature results in localized combustion. To avoid such burns, the plasma is currently being moved over the site to be treated at a certain rate.
Eine weitere Reizung (Irritation) der Haut, die sich in einem unangenehmen ”Kribbeln” äußert, wird durch den elektrischen Strom hervorgerufen, der von der Hochspannungselektrode (
Wie in der Hauptanmeldung beschrieben, besteht ein Vorteil vor allem darin, dass durch die Integration von Plasmadüse, Hochspannungsspule und HF-Generator in einem handlichen Plasmawerkzeug die Kabelverbindung zwischen Plasmaquelle(-„Plasmadüse”) und Hochspannungsquelle entfällt und somit das Problem der elektromagnetischen Verträglichkeit gelöst wird. Andererseits bietet sich durch die Miniaturisierung des Plasmawerkzeugs die Möglichkeit der Anwendung für punktgenaue, lokale Mikroplasmabehandlungen.As described in the parent application, there is an advantage in particular that the integration of plasma nozzle, high voltage coil and RF generator in a handy plasma tool eliminates the cable connection between plasma source (- "plasma nozzle") and high voltage source and thus solves the problem of electromagnetic compatibility becomes. On the other hand, the miniaturization of the plasma tool offers the possibility of application for pinpoint, local micro-plasma treatments.
Die Erfindung stellt es sich einerseits zur Aufgabe, die genannten Nachteile (Reizung der Haut) zu beseitigen und andererseits eine Alternative zur Integration von Plasmadüse, Hochspannungsspule und HF-Generator gemäß Hauptanmeldung bereitzustellen.On the one hand, the object of the invention is to eliminate the mentioned disadvantages (irritation of the skin) and, on the other hand, to provide an alternative to the integration of plasma nozzle, high voltage coil and HF generator according to the parent application.
Die Aufgabe wurde gemäß den Merkmalen der Patentansprüche gelöst.The problem has been solved according to the features of the claims.
Überraschenderweise hat sich herausgestellt, dass mit der erfindungsgemäßen Lösung im Bereich der erzeugten Spezies ein feldfreies Gebiet erzeugt, d. h. Elektronen und Ionen weitgehend „abgesaugt” wurden. Außerdem ist es gelungen, die Plasmadüse weiter zu miniaturisieren und damit auch an schwer zugänglichen Stellen eine lokale Plasmabehandlung vornehmen zu können.Surprisingly, it has been found that with the solution according to the invention in the area of the species produced, a field-free region is produced, ie. H. Electrons and ions were largely "sucked off". In addition, it has been possible to further miniaturize the plasma nozzle and thus be able to perform a local plasma treatment even in hard to reach places.
Die im Stand der Technik erwähnten Irritationen durch zu hohe Temperaturen und durch den elektrischen Strom wurden erfindungsgemäß wie folgt unterbunden:The irritations due to excessively high temperatures and the electric current mentioned in the prior art were prevented according to the invention as follows:
In
Die zur Behandlung notwendigen Spezies und die Strahlung stehen jedoch, wenn auch etwas gemindert, hinter dem Spalt zur Verfügung. Die antimikrobielle Wirkung konnte nachgewiesen werden.However, the species and radiation necessary for treatment are available, albeit somewhat diminished, behind the cleft. The antimicrobial effect could be proven.
Gleichzeitig wird durch diese Kappe die thermische Energie aufgenommen und die Temperaturen sind so gering, dass eine permanente Behandlung auf der Haut, auch in sensiblen Bereichen, erfolgen kann.At the same time the thermal energy is absorbed by this cap and the temperatures are so low that a permanent Treatment on the skin, even in sensitive areas, can be done.
Der entscheidende Vorteil ist, dass eine solche annehmbare Kappe eine Option für den Anwender darstellt. Benötigt er ein „kräftigeres” Plasma, dann arbeitet er ohne Kappe. Die Kappe wird – je nach Anwendungsgebiet – einfach aufgeschoben oder abgezogen.The key advantage is that such an acceptable cap is an option for the user. If he needs a "stronger" plasma, then he works without a cap. The cap is - depending on the application - simply pushed or peeled off.
Die Alternative zur Integration von Plasmadüse, Hochspannungsspule und HF-Generator gemäß Hauptanmeldung besteht darin, dass man, wie in
Diese Anordnung ermöglicht es, die Plasmadüse weiter zu miniaturisieren und damit auch an schwer zugänglichen Stellen eine lokale Plasmabehandlung vornehmen zu können.This arrangement makes it possible to further miniaturize the plasma nozzle and thus be able to make a local plasma treatment even in hard to reach places.
In diesem Fall müssen allerdings zusätzliche Maßnahmen zur Vermeidung einer erhöhten elektromagnetischen Störabstrahlung ergriffen werden.In this case, however, additional measures must be taken to avoid increased electromagnetic interference radiation.
Diese Anordnung bietet darüber hinaus die Möglichkeit, die Plasmadüse durch eine andere, an das zu behandelnde Objekt angepasste, externe Plasmaquelle zu ersetzen.This arrangement also offers the possibility to replace the plasma nozzle by another, adapted to the object to be treated, external plasma source.
