Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Erzeugung von Kaltluft für medizinische Zwecke.The invention relates to a device for generating cold air for medical purposes.
Kaltluft kann bei verschiedenen Krankheitssymptomen nützlich sein. Beispielsweise können rheumatische Beschwerden an Gelenken durch Anwendung von Kaltluft günstig beeinflusst werden. Außerdem können Blutungen durch Beaufschlagung mit Kaltluft gestilit werden. Schließlich können asthmatische Beschwerden gemildert werden, wenn der Patient trockene, keimfreie Kaltluft einatmen kann. Im Übrigen ist es bekannt, durch gezielten Einsatz von Kälte bei einer sogenannten Kryotherapie therapeutische Effekte zu bewirken, vgl. z. B. die Empfehlungen der Deutschen Dermatologischen Gesellschaft zur Qualitätssicherung „Kryochirurgie in der Dermatologie”,
Grundsätzlich ist es möglich, Kaltluft mit üblichen Wärmepumpen mit einem Kältemittelkreislauf zu erzeugen. Allerdings ist der damit verbundene Aufwand vergleichsweise hoch.Basically, it is possible to produce cold air with conventional heat pumps with a refrigerant circuit. However, the associated effort is comparatively high.
Deshalb ist es Aufgabe der Erfindung, ein zur Kaltlufterzeugung geeignetes Gerät mit besonders einfacher Konstruktion und hoher Robustheit zu schaffen.It is therefore an object of the invention to provide a device suitable for producing cold air with a particularly simple construction and high robustness.
Diese Aufgabe wird erfindungsgemäß mit einem Ranque-Hilsch-Wirbelrohr gelöst, welches eingangsseitig an die Druckseite eines saugseitig mit der Atmosphäre verbundenen Kompressors angeschlossen ist.This object is achieved with a Ranque-Hilsch vortex tube, which is connected on the input side to the pressure side of a suction side connected to the atmosphere of the compressor.
Ein Ranque-Hilsch-Wirbelrohr ist grundsätzlich bekannt, bspw. aus der
Gleichwohl bietet es die Möglichkeit, ohne jegliche bewegliche Teile Kalt- und Warmluft erzeugen zu können, wenn Druckluft zur Verfügung steht.Nevertheless, it offers the possibility of being able to generate cold and warm air without any moving parts when compressed air is available.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, an der Saugseite des Kompressors einen Luftfilter anzuordnen.According to a preferred embodiment of the invention, it is provided to arrange an air filter on the suction side of the compressor.
Desweiteren ist vorzugsweise ein nach dem Verdrängerprinzip arbeitender Kompressor vorgesehen, dessen Verdrängerarbeitsräume mit einer Membran hermetisch abgedichtet sind.Furthermore, a compressor operating according to the displacement principle is preferably provided, whose displacer working spaces are hermetically sealed with a membrane.
Auf diese Weise lässt sich gewährleisten, dass die vom eingangsseitigen Filter kommende Luft innerhalb des Kompressors frei von Verunreinigungen, wie bspw. ölhaltigen Aerosolen oder dergleichen, bleibt. In das Material der Membran sind bevorzugt Nanopartikel aus Silber und/oder Kupfer bzw. Silber/Kupfer/Legierungen eingebettet, so dass antiseptische Eigenschaften gegeben sind.In this way, it can be ensured that the air coming from the input-side filter inside the compressor remains free of contaminants, such as, for example, oil-containing aerosols or the like. In the material of the membrane are preferably embedded nanoparticles of silver and / or copper or silver / copper / alloys, so that antiseptic properties are given.
Beim Betrieb eines Ranque-Hilsch-Wirbelrohrs entstehen charakteristische Pfeifgeräusche. Deshalb ist gemäß einer besonders bevorzugten Ausführungsform der Erfindung ein Schalldämpfergehäuse vorgesehen, wobei gegebenenfalls eine Geräuschauslöschung durch Gegenschall vorgesehen sein kann. Im Ergebnis kann damit ein weitestgehend geräuschfreier Betrieb gewährleistet werden.The operation of a Ranque-Hilsch vortex tube produces characteristic whistling noises. Therefore, according to a particularly preferred embodiment of the invention, a silencer housing is provided, wherein optionally a noise canceling by counter sound can be provided. As a result, a largely noise-free operation can be ensured.
Im Übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche und die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der bevorzugte Ausführungsformen der Erfindung näher beschrieben werden.Incidentally, with regard to preferred features of the invention to the claims and the following explanation of the drawing, reference is made to the preferred embodiments of the invention will be described in more detail.
Schutz wird nicht nur für angegebene oder dargestellte Merkmalskombinationen sondern auch für prinzipiell beliebige Kombinationen der angegebenen oder dargestellten Einzelmerkmale beansprucht.Protection is claimed not only for specified or illustrated feature combinations but also for any combinations of the specified or illustrated individual features.
