Abstract

A transparent interception container (5), is installed in the conveying system (2) in front of prim filter (3) retaining bacteria and viruses. The container provides a receptacle for drawn-up fluids, e.g. blood, viscous secretions, mucus and similar. V valve mechanism (6) is provided on or in the container to close the conveying system when the container is full. An end switch is provided to interrupt the electromotor driving the vacuum pump when the container is full. The container is easily exchangeable. The suction appliance (1) includes an intermediate filter protecting the electromoter, an active carbon filter reducing smell and ventilation filter approaching nearly 100 per cent filtering efficiency. USE- Operational area for laser or h.f. surgery.

Description

Die Erfindung bezieht sich auf ein Gerät zum Absaugen von Rauchgasen und Entfernen von Viren und Bakterien aus dem Operationsfeld bei Anwendung der Laser- oder Hochfrequenzchirurgie, das im wesentlichen aus einer elektromotorisch angetriebenen Vakuumpumpe und mehreren Filtern besteht, die in einem Leitungssystem zwischen einem Absaugetrichter o. dgl. und der Vakuumpumpe angeordnet sind.The invention relates to a device for vacuuming Flue gases and removal of viruses and bacteria from the Operating field when using laser or high-frequency surgery, that essentially consists of an electric motor driven vacuum pump and several filters that exist in a line system between a suction funnel or the like and the vacuum pump are arranged.

Bei der Handhabung derartiger Geräte läßt es sich nicht immer vermeiden, daß Flüssigkeiten aufgesaugt werden. Da diese Flüssigkeiten das Filtersystem, insbesondere einen Bakterien- und virenretentiven Filter schnell verstopfen und damit unbrauchbar machen, sieht die Erfindung zur vorteilhaften Behebung dieses Umstandes einen insbesondere durchsichtigen Auffangbehälter für aufgesaugte Flüssigkeiten, z. B. Blut, schleimige Sekrete o. dgl. vor, der in dem Leitungssystem des Gerätes vor einem Bakterien- und virenretentivem Primärfilter angeordnet ist. Durch einen derartigen Auffangbehälter wird vorteilhaft erreicht, daß der Primärfilter, der nach jeder Operation ausgewechselt wird, während der Operation voll funktionsfähig bleibt.When handling such devices, it is not always possible avoid liquids being sucked up. This one Liquids the filter system, especially a bacterial and virus-clogging filters quickly clog up with them make useless, the invention looks advantageous Eliminate this circumstance, especially a transparent one Collection container for absorbed liquids, e.g. B. blood, slimy secretions or the like in front of the Device in front of a bacteria and virus-retentive primary filter is arranged. Through such a container advantageously achieved that the primary filter after each Operation is replaced during the full operation remains functional.

In vorteilhafter Ausgestaltung des Erfindungsgegenstandes kann im oder am Auffangbehälter ein Ventilmechanismus vorgesehen sein, der das Leitungssystem bei vollem Auffangbehälter schließt, so daß nicht abgesaugt werden kann und damit angezeigt wird, daß der Auffangbehälter ausgewechselt werden muß. In an advantageous embodiment of the subject matter of the invention a valve mechanism is provided in or on the collecting container be the line system when the container is full closes so that can not be suctioned off and so indicates that the waste container is to be replaced got to.  

Nach einem weiteren Merkmal kann auch ein Einschalter vorgesehen sein, der bei vollem Auffangbehälter den Antrieb der Vakuumpumpe unterbricht.According to a further feature, a switch can also be provided be the drive of the vacuum pump when the collecting container is full interrupts.

Schließlich kann der Auffangbehälter leicht auswechselbar angeordnet sein.Finally, the container can be easily replaced be arranged.

In der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel schematisch dargestellt.In the drawing, the subject of the invention is in one Exemplary embodiment shown schematically.

Das Gerät 1 zum Absaugen von Rauchgasen und Entfernen von Viren und Bakterien aus dem Operationsfeld bei Anwendung der Laser- oder Hochfrequenzchirurgie ist mit einer elektromotorisch angetriebenen Vakuumpumpe versehen, an die ein Leitungssystem 2 angeschlossen ist. In dieses Leitungssystem 2 ist im Inneren des Gerätes ein den Elektromotor schützender Zwischenfilter, ein Aktivkohlefilter zur Geruchsreduzierung und ein Abluftfilter eingeschaltet, der zu dem nahezu 100%igen Filterwirkungsgrad beiträgt. Außerhalb des Gerätes 1 ist ein Primärfilter 3 im Leitungssystem 2 angeordnet, der Bakterien- und Virenretentiv ist. Damit dieser Primärfilter 3 beim Ansaugen von Flüssigkeiten, z. B. Blut oder schleimige Sekrete, nicht wirkungslos wird, ist im Leitungssystem 2 zwischen dem Primärfilter 3 und der Ansaugöffnung 4 ein durchsichtiger Flüssigkeitsbehälter 5 leicht auswechselbar angeordnet. In oder am Flüssigkeitsbehälter 5 befindet sich ein Ventilmechanismus 6, der bei vollem Flüssigkeitsbehälter 5 das Leitungssystem 2 abschließt, so daß nicht mehr abgesaugt werden kann. Die Vakuumpumpe im Gerät verträgt diesen Zustand, zumindest so lange, bis der Flüssigkeitsbehälter ausgetauscht wurde. Anstelle des Ventilmechanismus 6 kann auch ein Schalter vorgesehen sein, der den Antrieb der Vakuumpumpe stillsetzt.The device 1 for extracting smoke gases and removing viruses and bacteria from the operating field when using laser or high-frequency surgery is provided with an electric motor-driven vacuum pump to which a line system 2 is connected. In this line system 2 , an intermediate filter protecting the electric motor, an activated carbon filter for reducing odor and an exhaust air filter are connected in the interior of the device, which contributes to the almost 100% filter efficiency. Outside the device 1 , a primary filter 3 is arranged in the line system 2 , which is bacterial and virus retentive. So that this primary filter 3 when sucking liquids, for. B. blood or slimy secretions, is not ineffective, a transparent liquid container 5 is arranged in the line system 2 between the primary filter 3 and the suction opening 4 easily replaceable. In or on the liquid container 5 there is a valve mechanism 6, which the line system 2 terminates with a full liquid container 5, so that it can no longer be aspirated. The vacuum pump in the device tolerates this condition, at least until the liquid container has been replaced. Instead of the valve mechanism 6 , a switch can also be provided which stops the drive of the vacuum pump.
