Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine sog. Operations-' kabine, d.h. einen besonders gebauten Operationsraum, bei dem die Belüftung durch die Zufuhr hochgradig gereinigter Belüftungsluft erfolgt, die die Operationskabine senkrecht durchströmt.The present invention relates to a so-called operation 'cabin, i.e. a specially built operating room, where ventilation is provided by the supply of highly cleaned ventilation air that flows vertically through the operating room.
Eine große Anzahl von Infektionen wird bei gewissen Typen von Ope- rationen dadurch verursacht, daß Infektionsträger durch die Luft übertragen werden. Besonders groß ist diese Gefahr bei umfangreicheren orthopädischen Eingriffen. Die Infektionshäufigkeit bei derartigen Operationen kann sich auf mehrere Prozent der Operatio- nen belaufen, wenn nicht besondere Vorkehrungen getroffen werden.A large number of infections in certain types of Ope - rations thereby causing infection carriers are transmitted through the air. This risk is particularly great for extensive orthopedic interventions. The incidence of infection in such operations may amount to several percent of the operations, unless special precautions are taken.
Etliche Untersuchungen in den letzten Jahren haben gezeigt, daß sich die Infektionshäufigkeit wesentlich reduzieren läßt, wenn die Luft hochgradig von Bakterien befreit wird. Dies kann auf die Weise geschehen, daß in den Operationsräumen herkömmlicher Ausführung spezielle Operationskanmern oder, näher gesagt, sog. Operationskabinen installiert werden.Several studies in recent years have shown that the frequency of infections can be significantly reduced if the air is cleared of bacteria to a high degree. This can be done in such a way that special operating rooms or, more precisely, so-called operating rooms are installed in the operating rooms of conventional design.
Kennzeichnende Merkmale derartiger Operationskabinen sind, daß die zugeführte Luft in einem Absolutfilter gereinigt wird und die gesamte Luftmenge die Kabine mit hauptsächlich gleicher Richtung und Geschwindigkeit durchströmt. Man unterscheidet zwischen Operationskabinen für waagrechte Luftdurchströmung und Operationskabinen für senkrechte Luftdurchströmung. Bei der waagrechten Luftdurchströmung geschieht die Luftzufuhr durch ein in einer Wand installiertes Absolutfilter, bei senkrechter Luftdurchströmung durch eine Filtergruppe in der Kabinendecke.Characteristic features of such operating cabins are that the air supplied is cleaned in an absolute filter and the total amount of air flows through the cabin with mainly the same direction and speed. A distinction is made between operating cabins for horizontal air flow and operating cabins for vertical air flow. With horizontal air flow, the air is supplied through an absolute filter installed in a wall, with vertical air flow through a filter group in the cabin ceiling.
In jüngster Zeit erhaltene Forschungsergebnisse haben eindeutig den Nachweis erbracht, daß bei senkrechter Luftdurchströmung der Operationskabine die niedrigste Infektionshäufigkeit erhalten wird. Bei einer großen, auf internationaler Ebene durchgeführten Untersuchung zeigten sich beispielsweise durchschnittlich 2 kulturenbildende Einheiten je m3 bei senkrechter und 22 Einheiten je m3 bei waagrechter Luftdurchströmung, wobei das in der Operationskabine tätige Personal in beiden Fällen konventionelle OP-Kleidung trug.Recent research results have clearly shown that the lowest frequency of infection is obtained with a vertical air flow through the operating room. For a large, international level Investigation showed, for example, an average of 2 culture-forming units per m 3 with vertical air flow and 22 units per m 3 with horizontal air flow, whereby the personnel working in the operating room wore conventional surgical clothing in both cases.
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.
Vorliegende Erfindung bezieht sich auf eine Operationskabine mit senkrechter Luftdurchströmung, wobei die Kabine jeweils eine der folgenden Forderungen erfüllen kann: Entweder erhält die Luft ihre absolut höchste erzielbare Reinheit, oder die Kabine bietet möglichst hohen Anwenderkomfort bei gleichzeitig hohem Reinheitsgrad der Luft. Möglich wurde dies durch die kennzeichnenden Merkmale einer Operationskabine gemäß Patentanspruch 1. Weitere Ausführungsformen der Erfindung gehen aus den anschließenden Patentansprüchen hervor. Die Operationskabine gemäß der Erfindung umfaßt ein Wandsystem mit sowohl festen als auch abnehmbaren Wandteilen, und dadurch wurde es möglich, in jedem einzelnen Operationsfall die Operationskabine den Forderungen anzupassen, die bei der jeweiligen Operation von vorrangiger Bedeutung sind.The present invention relates to an operating cabin with a vertical air flow, the cabin being able to meet one of the following requirements: Either the air obtains its absolute highest achievable purity, or the cabin offers the highest possible user comfort with a high degree of air purity. This was made possible by the characterizing features of an operating cabin according to
Eine nähere Beschreibung der Erfindung erfolgt mit Hinweis auf die beiliegenden Abbildungen, wobei:
- Abb. 1 schematisch die Operationskabine und das an der Kabine angeschlossene Zuluftaggregat im Querschnitt zeigt und
- Abb. 2 die Operationskabine schematisch in perspektivischer Darstellung zeigt.
- Fig. 1 shows a schematic cross section of the operating cabin and the supply air unit connected to the cabin
- Fig. 2 shows the operating cabin schematically in perspective.
Wie aus Abb. 1 und 2 hervorgeht, ist die Operationskabine in 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.As can be seen from Figs. 1 and 2, the operating cabin is suspended in the
Die festen Wände der Operationskabine sind so ausgeführt, daß sie ca. 2,1 m oberhalb des Fußbodens, d.h. etwas über Kopfhöhe, enden. Diese festen Wände 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 mit sowohl festen als auch abnehmbaren Wänden eine verhältnismäßig kurze und dadurch handhabungsfreundliche Ausführung der Wandelemente erlaubt.The fixed walls of the operating room are designed so that they are approx. 2.1 m above the floor, i.e. something above head height. These fixed walls 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 on one end of the operating room are provided 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 room according to the invention with both fixed and removable walls, it is possible to meet different requirements with one and the same operating room. The lowest possible bacterial content is at An Turning 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.
