Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Überprüfung und/oder Überwachung der Luftströmung in einem Arbeitsraum, wie Operationsraum, mit in diesem angeordneten Arbeitsplatz, wie Operationstisch.The invention relates to a method for checking and / or monitoring the flow of air in a work space, such as operating room, with arranged in this workplace, such as operating table.
Auch nimmt die Erfindung Bezug auf ein Verfahren zum Konditionieren der Luft in einem Raum, insbesondere Reinraum wie Operationsraum, dem über einen Arbeitsbereich, wie Operationstisch, und auf diesen gerichtet laminar turbulenzarm strömende Luft zugeführt wird.The invention also relates to a method for conditioning the air in a room, in particular a clean room such as operating room, which is supplied via a work area, such as operating table, and laminar directed turbulence air flowing thereon.
Schließlich nimmt die Erfindung Bezug auf einen Operationstisch mit Liegefläche und stirnseitigen Enden.Finally, the invention relates to an operating table with lying surface and front ends.
In Reinräumen ist sicherzustellen, dass unter Arbeitsbedingungen definierte Grenzwerte der Konzentration an Luft getragener Kontamination eingehalten werden.In clean rooms it must be ensured that limits of the concentration of airborne contaminants defined under working conditions are met.
In Operationsräumen mit turbulenzearmer Verdrängungsströmung zur Erzielung eines Schutzbereichs, in dem die Operation stattfindet und die Instrumententische positioniert sind, soll eine turbulenzarme Abwärtsströmung gewährleistet sein. Hierdurch wird eine Verwirbelung der Luft im Operationsfeld weitestgehend vermieden, so dass die in das Operationsfeld von der Decke zuströmende keimarme Zuluft nur im zulässigen Umfang kontaminiert werden kann.In operating rooms with low-turbulence displacement flow to achieve a protection area in which the operation takes place and the instrument tables are positioned, a turbulence-poor downflow is to be ensured. As a result, a turbulence of the air in the surgical field is largely avoided, so that the inflowing into the surgical field from the ceiling low-germ supply air can be contaminated only to an acceptable extent.
Durch ein nichtordnungsgemäßes Verhalten wie Bewegen von Personen im Bereich des Operationsfelds und/oder nicht ordnungsgemäßes Anordnen von Geräten in dem Zuluftstrom können Turbulenzen auftreten, die zu einer unzulässigen Kontamination und somit Gefährdung der zu operierenden Person führen kann. Dies kann sich z. B. durch zu einem späteren Zeitpunkt auftretende Entzündungen äußern.By improper behavior such as moving people in the area of the surgical field and / or improper placement of devices in the supply air flow turbulence may occur, which can lead to unacceptable contamination and thus endanger the person to be operated. This can be z. B. by manifesting inflammation occurring at a later date.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie einen Operationstisch der eingangs genannten Art so weiterzubilden, dass mit einfachen Maßnahmen Rückschlüsse über die Art der Luftströmung erzielbar sind. Es soll indirekt eine Qualitätssicherung über die im Arbeitsbereich herrschende Strömung ermöglicht werden.The present invention has the object, a method and an operating table of the type mentioned in such a way that with simple measures conclusions about the nature of the air flow can be achieved. It is intended to indirectly ensure quality assurance of the prevailing flow in the work area.
Zur Lösung der Aufgabe sieht ein Verfahren zur Überprüfung und/oder Überwachung der Luftströmung in einem Arbeitsraum, wie Reinraum, insbesondere Operationsraum, mit in diesem angeordneten Arbeitsplatz, wie Operationstisch, vor, dass in, an oder im Bereich des Arbeitsplatzes zumindest eine Strömungssonde angeordnet wird, mittels der die Turbulenz des Luftstroms im Bereich des Arbeitsplatzes gemessen wird.To solve the problem provides a method for checking and / or monitoring the air flow in a workspace, such as clean room, especially operating room, arranged in this workstation, such as operating table, that is arranged in, on or in the workplace at least one flow probe by means of which the turbulence of the air flow in the area of the workplace is measured.
Aufgrund der erfindungsgemäßen Lehre wird unmittelbar in dem Bereich, in dem eine gewünschte Strömung herrschen soll, eine Überprüfung dieser vorgenommen, um z. B. rückwirkend nachvollziehen zu können, welche Beeinflussung die gemessene Strömung auf das Arbeitsergebnis hatte. Insbesondere handelt es sich bei dem Arbeitsplatz um einen Operationstisch, wobei zumindest im Bereich einer jeden Stirnseite des Operationstischs zumindest jeweils eine Strömungssonde angeordnet wird.Due to the teaching of the invention, a check of this is made directly in the area in which a desired flow is to prevail in order to z. B. to be able to retrospectively understand what influence the measured flow had on the work result. In particular, the workstation is an operating table, wherein at least one flow probe is arranged at least in the area of each end face of the operating table.
In eigenerfinderischer Weiterbildung der Erfindung ist vorgesehen, dass die Turbulenz online gemessen und bei Überschreitung eines festgelegten Turbulenzgrades von z. B. 30% ein Signal generiert und/oder in den Arbeitsbereich strömende Luft in Bezug z. B. auf Richtung und/oder Menge und/oder Strömungsart geregelt wird.In ownfinderischer development of the invention it is provided that the turbulence measured online and when exceeding a specified degree of turbulence of z. B. 30% generates a signal and / or air flowing into the work area in relation to z. B. is regulated in direction and / or amount and / or flow.
Es erfolgt ein adaptives System, durch das sichergestellt wird, dass optimale Strömungsverhältnisse im Bereich des Arbeitsplatzes, insbesondere eines Operationstisches herrschen können.There is an adaptive system, which ensures that optimal flow conditions prevail in the workplace, in particular a surgical table.
Des Weiteren sieht die Erfindung vor, dass der über die zumindest eine Strömungssonde gemessene Turbulenzgrad abgespeichert wird. Es erfolgt eine Archivierung der Ergebnisse, um diese sodann mit Daten von z. B. Arbeits- wie Operationsfolgen vergleichen zu können.Furthermore, the invention provides that the turbulence degree measured via the at least one flow probe is stored. There is an archiving of the results, in order then this with data from z. For example, to be able to compare work and operation sequences.
Insbesondere ist vorgesehen, dass in jedem Stirnbereich des Operationstisches zumindest eine Strömungssonde angeordnet bzw. in dem Operationstisch integriert wird.In particular, it is provided that at least one flow probe is arranged or integrated in the operating table in each end area of the operating table.
Ein Verfahren zum Konditionieren der Luft in einem Raum, insbesondere Reinraum wie Operationsraum, dem über einen Arbeitsbereich, wie Operationstisch, und auf diesen gerichtet laminar turbulenzarm strömende Luft zugeführt wird, zeichnet sich dadurch aus, dass im Arbeitsbereich zumindest eine den Turbulenzgrad der strömenden Luft messende Sonde angeordnet wird und dass in Abhängigkeit des gemessenen Turbulenzgrads die zuströmende Luft geregelt wird. Insbesondere wird Geschwindigkeit und Menge der zugeführten Luft geregelt.A method for conditioning the air in a room, in particular a clean room such as operating room, which is supplied laminar turbulence over a working area, such as operating table, and directed laminar, characterized in that at least one of the turbulence degree of the flowing air measuring in the work area Probe is arranged and that, depending on the measured degree of turbulence, the inflowing air is controlled. In particular, the speed and amount of the supplied air is regulated.
Ein Arbeitsplatz in Form eines Operationstisches umfassend eine Liegefläche mit stirnseitigen Enden zeichnet sich dadurch aus, dass im Bereich zumindest eines stirnseitigen Endes eine Strömungssonde angeordnet ist. Insbesondere sieht die Erfindung vor, dass der Operationstisch zumindest in einem stirnseitigen Ende in Verlängerung der üblichen Liegefläche eine Aufnahme für die zumindest eine Strömungssonde aufweist.A workplace in the form of a surgical table comprising a lying surface with frontal ends is characterized in that a flow probe is arranged in the region of at least one end face. In particular, the invention provides that the operating table has a receptacle for the at least one flow probe, at least in an end face in extension of the usual lying surface.
Bevorzugterweise handelt es sich bei der Aufnahme um einen stirnseitigen Ansatz an den Operationstisch, so dass dieser übliche Abmessungen und Konstruktionen aufweisen kann.Preferably, the receptacle is a frontal approach to the operating table so that it may have conventional dimensions and constructions.
Vorzugsweise sind in jedem stirnseitigen Ende zumindest jeweils eine Strömungssonde, vorzugsweise zwei Strömungssonden angeordnet.Preferably, at least one flow probe, preferably two flow probes, are arranged in each front end.
