Definitions
- the invention relates to an operating cabin for vertical air flow, which is suspended from the ceiling of an operating room and has a filter ceiling, a wall construction for the connections to at least one supply air unit with fans and prefilter.
- Operating cabins for vertical air flow of the type mentioned at the outset are known in two different basic designs.
- the side walls of the operating cabin are made in one piece and attached to the ceiling of the operating room (FR-A-2 089 467).
- This embodiment has the disadvantage that the size of the operating cabin delimited by the side walls cannot be changed in order to be able to adapt it to the different requirements given in different operations.
- the accessibility of the operating room can be improved by the fact that at least one side wall of the operating room is at least partially formed by curtains which are suspended from an upper fixed part of this side wall (DE-A-2 449 573) . Since this known operating cabin is set up and fastened on the wall corners above feet or vertical posts on the floor of the operating room, it can only be opened to a limited extent. The operating cabin of this version can therefore not be adapted to the different space requirements in small and large operations.
- the invention is therefore based on the object of designing the operating cabin of the type mentioned for vertical air flow in such a way that it can be optimally adapted to the respective space requirements in different operations, in order to achieve the highest possible degree of purity of the ventilation air.
- the wall construction of the operating cabin consists partly of fixed wall parts attached to the ceiling and partly of wall elements which are detachably suspended and reach almost to the floor of the operating room.
- Fig. 1 the operating cabin and the supply air unit connected to the cabin in vertical cross section and
- Fig. 2 shows the operating cabin schematically in perspective.
- the operating cabin is suspended from the ceiling 10 of the operating room.
- the supply air unit 1 which provides the operating room with cleaned air, is installed in the example shown in a room above the actual operating room.
- the supply air unit 1 contains a fan 2, a prefilter 3 and the necessary sound insulation devices.
- the air coming from the supply air unit is distributed in a pressure chamber 4 before it flows through the absolute filter 5, the degree of separation of which is high and amounts to at least 99.9%.
- the fixed wall parts of the operating cabin are designed so that they are approx. 2.1 m above the floor, i.e. something above head height.
- These fixed wall parts 6 are provided with fastening elements 7, on which a number of loose wall elements 8 are suspended.
- the wall elements 8 are provided with handles 11 for easier hanging and removal. It should be noted that the selected wall construction with both fixed and removable wall parts allows a relatively short and therefore easy to use design of the wall elements.
- two of the wall elements are on one end of the operating room with through openings 12 for pass-through of instruments.
- the wall elements 8 end approximately 100-300 mm above the floor, so that the ventilation air can flow out through the gap between the wall elements and the floor.
- the operating table 9 is usually permanently installed in the operating cabin.
- the operating cabin according to the invention By designing the operating cabin according to the invention with both fixed and removable walls, it is possible to meet different requirements with one and the same operating cabin.
- the lowest possible bacterial content is achieved when using the wall elements 8. If the wall elements 8 are removed, on the other hand, the freedom of movement of the personnel working in the operating cabin is improved, while at the same time a low bacterial content can still be maintained.

Abstract
Description
Die Erfindung betrifft eine Operationskabine für senkrechte Luftdurchströmung, die an der Decke eines Operationssaales aufgehängt ist und eine Filterdecke, eine Wandkonstruktion für die Anschlüsse an mindestens ein Zuluftaggregat mit Ventilatoren und Vorfilter aufweist. Mit Operationskabinen innerhalb von Operationssälen kann eine wesentlichen Reduzierung der Infektionsgefahren erreicht werden, denn die gesamte solchen Operationskabinen zugeführte Luft kann optimal vorgereinigt und zum gleichmäßigen Hindurchströmen durch die Kabine und anschließenden Abströmen nach außen gebracht werden.The invention relates to an operating cabin for vertical air flow, which is suspended from the ceiling of an operating room and has a filter ceiling, a wall construction for the connections to at least one supply air unit with fans and prefilter. A significant reduction in the risk of infection can be achieved with operating cabins within operating rooms, because all the air supplied to such operating cabins can be optimally pre-cleaned and brought to the outside to flow evenly through the cabin and subsequent outflow.
In jüngster Zeit erzielte Forschungsergebnisse haben den Nachweis erbracht, daß bei senkrechter Luftdurchströmung von Operationskabinen die geringste Infektionsgefahr besteht. Bei einer auf internationaler Ebene durchgeführten Untersuchung ergaben sich beispielsweise durchschnittlich zwei Kulturen bildende Einheiten je m3 bei senkrechter und 22 Einheiten je m3 bei waagerechter Luftdurchströmung, wobei das in den Operationskabinen tätige Personal in beiden Fällen konventionelle OP-Kleidung trug.Recent research results have shown that there is the least risk of infection if the air flow through the operating cabin is vertical. In an investigation carried out at international level, for example, an average of two culture-forming units were found per m 3 with vertical air flow and 22 units per m 3 with horizontal air flow.
Der für senkrechte Luftdurchströmung angegebene Wert bezieht sich auf Operationskabinen mit Wänden. Es liegen auch Ergebnisse für senkrecht durchströmte Kabinen ohne Wände vor. In diesem Fall ergab oben genannte, internationale Untersuchung einen durchschnittlichen Gehalt von 10 kulturenbildenden Einheiten je m3. Obwohl diese vereinfachten Kabinen nicht die gleichen guten Luftreinheitsergebnisse erbringen, werden sie häufig gewählt, weil die Tätigkeit in einer Operationskabine mit Wänden häufig als unbequem betrachtet wird.The value given for vertical air flow refers to operating rooms with walls. There are also results for vertically flow through cabins without walls. In this case, the above-mentioned international investigation showed an average salary of 10 culture-forming units per m 3 . Although these simplified cabins do not produce the same good air purity results, they are often chosen because working in a wall-mounted operating room is often considered uncomfortable.
Operationskabinen für senkrechte Luftströmung der eingangs genannten Gattung sind in zwei verschiedenen prinzipiellen Ausführungen bekannt. Bei der einen Ausführung sind die Seitenwände der Operationskabine durchgehend einstückig ausgebildet und an der Decke des Operationssaales befestigt (FR-A-2 089 467). Diese Ausführung hat den Nachteil, daß die Größe der von den Seitenwänden begrenzten Operationskabine nicht verändert werden kann, um sie den bei unterschiedlichen Operationen gegebenen verschiedenartigen Anforderungen anpassen zu können. Bei der zweiten bekannten Ausführung kann zwar die Zugängigkeit der Operationskabine verbessert werden, und zwar dadurch, daß mindestens eine Seitenwand der Operationskabine zumindest teilweise von Vorhängen gebildet wird, die an einem oberen festen Teil dieser Seitenwand aufgehängt sind (DE-A-2 449 573). Da diese bekannte Operationskabine an den Wandecken über Füße oder senkrechte Pfosten auf dem Boden des Operationssaales aufgestellt und dort befestigt ist, kann sie jedoch nur beschränkt geöffnet werden. Auch die Operationskabine dieser Ausführung kann daher nicht an die bei kleinen und großen Operationen unterschiedlichen Raumbedürfnisse angepaßt werden.Operating cabins for vertical air flow of the type mentioned at the outset are known in two different basic designs. In one embodiment, the side walls of the operating cabin are made in one piece and attached to the ceiling of the operating room (FR-A-2 089 467). This embodiment has the disadvantage that the size of the operating cabin delimited by the side walls cannot be changed in order to be able to adapt it to the different requirements given in different operations. In the second known embodiment, the accessibility of the operating room can be improved by the fact that at least one side wall of the operating room is at least partially formed by curtains which are suspended from an upper fixed part of this side wall (DE-A-2 449 573) . Since this known operating cabin is set up and fastened on the wall corners above feet or vertical posts on the floor of the operating room, it can only be opened to a limited extent. The operating cabin of this version can therefore not be adapted to the different space requirements in small and large operations.
Der Erfindung liegt daher die Aufgabe zugrunde, die Operationskabine der eingangs genannten Gattung für senkrechte Luftströmung derart auszugestalten, daß sie an die jeweiligen Raumbedürfnisse bei unterschiedlichen Operationen optimal angepaßt werden kann, um somit auch den jeweils höchstmöglichen Reinheitsgrad der Belüftungsluft zu erzielen.The invention is therefore based on the object of designing the operating cabin of the type mentioned for vertical air flow in such a way that it can be optimally adapted to the respective space requirements in different operations, in order to achieve the highest possible degree of purity of the ventilation air.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst, nämlich dadurch, daß die Wandkonstruktion der Operationskabine teils aus an der Decke angebrachten festen Wandteilen und teils aus an diesen abnehmbar aufgehängten und fast bis zum Fußboden des Operationsraumes heranreichenden Wandelementen besteht. Mit der erfindungsgemäßen Ausbildung ist es möglich, die Operationskabine den bei den unterschiedlichen Operationen gegebenen verschiedenartigen Anforderungen genau anpassen zu können. Da die Wandteile nicht auf dem Boden des Operationssaales aufgeständert sind, kann durch Entfernen der abnehmbar aufgehängten Wandelemente die Kabine derart geöffnet werden, daß keine Teile an den Seiten der Kabine verbleiben, welche den Innenraum der Kabine seitlich begrenzen und die Operationstätigkeit behindern würden.This object is achieved by the features specified in the characterizing part of
Zweckmäßige Weiterbildungen der vorerwähnten Erfindung sind in den Ansprüchen 2 bis 6 gekennzeichnet.Advantageous developments of the aforementioned invention are characterized in
Ein besonders vorteilhaftes Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung beschrieben, wobeiA particularly advantageous embodiment of the invention is described below with reference to the drawing, wherein

Abb. 2 die Operationskabine schematisch in perspektivischer Darstellung zeigt.Fig. 2 shows the operating cabin schematically in perspective.
Wie aus Abb. 1 und 2 hervorgeht, ist die Operationskabine an der Decke 10 des Operationssaales aufgehängt. Das Zuluftaggregat 1, das die Operationskabine mit gereinigter Luft versieht, ist im gezeigten Beispiel in einem Raum oberhalb des eigentlichen Operationssaales aufgestellt. Das Zuluftaggregat 1 enthält einen Ventilator 2, ein Vorfilter 3 sowie die erforderlichen Schalldämmvorrichtungen. Die vom Zuluftaggregat kommende Luft wird in einer Druckkammer 4 verteilt, bevor sie das Absolutfilter 5 durchströmt, dessen Abscheidegrad hoch ist und mindestens 99,9% beträgt.1 and 2, the operating cabin is suspended from the
Die festen Wandteile der Operationskabine sind so ausgeführt, daß sie ca. 2,1 m oberhalb des Fußbodens, d.h. etwas über Kopfhöhe, enden. Diese festen Wandteile 6 sind mit Befestigungselementen 7 versehen, an denen eine Reihe loser Wandelemente 8 aufgehängt sind. Die Wandelemente 8 sind zum leichteren Aufhängen und Entfernen mit Griffen 11 versehen. Es sei darauf hingewiesen, daß die gewählte Wandbauweise mitsowohl festen als auch abnehmbaren Wandteilen eine verhältnismäßig kurze und dadurch handhabungsfreundliche Ausführung der Wandelemente erlaubt.The fixed wall parts of the operating cabin are designed so that they are approx. 2.1 m above the floor, i.e. something above head height. These fixed wall parts 6 are provided with
In dem in Abb. 2 dargestellten Beispiel sind zwei der Wandelemente an der einen Stirnseite der Operationskabine mit Durchgangsöffnungen 12 für u.a. ein Durchreichen von Instrumenten versehen. Die Wandelemente 8 enden ca. 100-300 mm über dem Fußboden, so daß die Belüftungsluft durch den Spalt zwischen den Wandelementen und dem Fußboden abströmen kann. Der Operationstisch 9 ist in der Regel fest in der Operationskabine installiert.In the example shown in Fig. 2, two of the wall elements are on one end of the operating room with through
Durch die Ausführung der Operationskabine gemäß der Erfindung mit sowohl festen als auch abnehmbaren Wänden ist es möglich, mit einer und dergleichen Operationskabine unterschiedliche Forderungen zu erfüllen. Der niedrigst mögliche Bakteriengehalt wird bei Anwendung der Wandelemente 8 erzielt. Wenn die Wandelemente 8 entfernt werden, verbessert sich andererseits die Bewegungsfreiheit des in der Operationskabine tätigen Personals, während gleichzeitig weiterhin ein niedriger Bakteriengehalt aufrechterhalten werden kann.By designing the operating cabin according to the invention with both fixed and removable walls, it is possible to meet different requirements with one and the same operating cabin. The lowest possible bacterial content is achieved when using the
Die Erfindung beschränkt sich nicht auf die oben beschriebene und in den Abbildungen dargestellte, nur dem Beispiel dienende Ausführungsform, sondern sie kann selbstverständlich im Rahmen der nachstehenden Patentansprüche verändert werden.The invention is not limited to the embodiment described above and shown in the figures, which serves only as an example, but can of course be changed within the scope of the following claims.
