Abstract

In order to achieve an optimally high degree of purity of the air supplied to an operating area it is proposed, according to the method, that the air to be supplied be used in a dual air system comprising a screening edge veil (5) and emerging laminar filling air (6). This is achieved, according to the device, in that the outer air veil (5) comprises an annularly arranged, preferably focusable annular veil nozzle system (3) which is preferably located on the outer casing of an operation theatre lamp, and the circular inner region of the lamp is designed as a preferably perforated exit area (4) for the inner laminar air supply (6) and jet formation, it being possible for the perforated exit area (6) to be formed thereby and/or between the individual lamps (2) or in front of these. <IMAGE>

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Verfahren und Vorrichtung zur gezielten Reinluftzuführung in das Operationsfeld Es ist bekannt, Operationsräume mit reiner Luft zu versorgen, um Sekundärinfektionen zu vermeiden."Process and device for targeted clean air supply into the Operating field It is known to supply operating rooms with clean air in order to Avoid secondary infections.

Dies führt jedoch nicht immer zum gewünschten Erfolg, weil stoßweise auftretende Verunreinigungen, beispielsweise durch Zutritt oder Weggang von Personen, die fallweise nicht den notwendigen Reinheitsgrad aufweisen, auftreten.However, this does not always lead to the desired success because it is intermittent Occurring contamination, for example due to the entry or departure of people, which in some cases do not have the necessary degree of purity.

Es gibt weiterhin das sogenannte Reinfeldverfahren, indem in der Decke angebrachte laminare Strömungen zur räumlichen Beschickung des OP-Tisches angewandt werden.There is still the so-called Reinfeld method by adding in the ceiling Applied laminar flows for spatial loading of the operating table will.

Weiterhin ist das Einleiten von Querströmungen durch Einzeldüsen und auch das Bilden von Luftschleiern durch schlauchförmige, variabel anzusetzende Elemente bekannt.Furthermore, the introduction of cross flows through individual nozzles and also the formation of air veils through tubular, variably attachable elements known.

Diese so eingesetzten Einzelströme erzeugen jedoch nachteilig wirkende Induktionsströme von angesaugter, nicht gereinigter Fremdluft, die dann unerwünscht wiederum verstärkt auftritt.However, these individual currents used in this way produce adverse effects Induction currents from sucked in, uncleaned external air, which are then undesirable again occurs more intensely.

Erfindungsgemäß wird daher vorgeschlagen, einen laminaren ausströmenden Flächenbereich durch äußere Ringschleierabsicherungen so abzuschirmen, daß die gereinigte Laminarluft gezielt an den einzuhaltenden Ort transportiert wird, und der sie umgebende Ringluftschleier einen Fremdluftzutritt verhindert.According to the invention it is therefore proposed to use a laminar outflow Shield the surface area with external ring curtain protection so that the cleaned Laminar air is specifically transported to the place to be maintained and the surrounding area Ring air curtain prevents external air from entering.

Hierzu wird erfindungsgemäß weiter zur Sicherung dieses Gewollten ausgeführt, daß durch die Luftmenge des sichernden Schleierstromes im Inneren des Systems ein Überdruck auftritt, der einen Fremdlufteinbruch innerhalb der zu schützenden Zone verhindert.To this end, according to the invention, further steps are taken to ensure that this is desired executed that by the amount of air of the securing veil flow inside the Systems an overpressure occurs, which causes an ingress of external air within the zone to be protected.

Gleichzeitig wird der Ringstrahlstrom so stark ausgebildet und gerichtet, daß der geschützte Laminarstrom gesichert bis auf die zu schützende Fläche auftritt.At the same time, the ring jet stream is so strongly developed and directed, that the protected laminar flow occurs securely up to the surface to be protected.

Weiterhin wird erfindungsgemäß vorgeschlagen, um nicht zusätzliche Abblendungen im Bereich des OP-Tisches riskieren zu müssen, die so und so vorhandene Lichtquelle, die in der Regel als kreisförmige Fläche ausgebildet ist, mit der eben erfindungsgemäß beschriebenen Technik auszubilden.Furthermore, it is proposed according to the invention to avoid additional Having to risk dimming in the area of the operating table, the one that exists in one way or another Light source, which is usually designed as a circular surface, with the plane train according to the invention described technique.

Außerdem wirkt sich die nach innen konkav gewölbte Fläche fokussierend auf den gewünschten Luftstrom aus.In addition, the inwardly concave surface has a focusing effect the desired airflow.

Durch diese erfindungsgemäße Kombination ist die Gewähr gegeben, daß so und so, wo die Lichtquelle richtstrahlmäßig angesetzt wird, auch die schützende Reinlufttechnik wirksam wird.This combination according to the invention ensures that so and so, where the light source is placed in the direction of a directional beam, also the protective one Clean air technology takes effect.

Die Fläche zwischen den einzelnen Lichtstrahlern wird erfindungsgemäß perforiert ausgebildet und der Rand der Lampe als Luftschleierdüse.The area between the individual light emitters is according to the invention perforated and the edge of the lamp as an air curtain nozzle.

Weiterhin wird erfindungsgemäß erreicht, daß durch Konditionieren der Luftmengen eine Kühl- oder Warmwirkung auf das Wundfeld wunschgemäß erzielt werden kann.Furthermore, it is achieved according to the invention that by conditioning the air volume achieves a cooling or warming effect on the wound area as desired can be.

In der beiliegenden Zeichnung ist dargestellt: mit (1) der OP-Tisch mit (2) die Lampenschirmlichtfläche mit (3) die fokussierbare, vorzugsweise schwenkbar ausgebildete Ringstrahldüsenanordnung mit (4) die perforierte Innenfläche des Lampenkörpers für die Laminarströmung mit (5) der randabdeckende, fokussierbare Ureib-und Schutz strahl mit (6) die austretende Laminarluft mit (7) ein erfindungsgemäß angeordnetes Reinluftgerät, das mit zur Abscheidung von gasförmigen Schadstoffen dient, wobei dieses Gerät auch in den OP-Tisch mit eingebaut wird und gleichzeitig eine Reinluftmenge zur Behandlung des OP-Besteckes freisetzt.The accompanying drawing shows: with (1) the operating table with (2) the lampshade light surface with (3) the focusable, preferably pivotable formed ring jet nozzle arrangement with (4) the perforated inner surface of the lamp body for the laminar flow with (5) the edge-covering, focusable friction and protection beam with (6) the exiting laminar air with (7) a according to the invention arranged clean air device, which is used for the separation of gaseous pollutants serves, whereby this device is also built into the operating table and at the same time releases a quantity of clean air for the treatment of the surgical instruments.

Dieses Gerät saugt die Umluft an, reinigt sie staubtechnisch und gastechnisch. This device sucks in the circulating air, cleans it with dust and gas technology.

Selbstverständlich kann dieses Gerät auch mit in den OP-Tisch eingebaut sein und gleichzeitig eine entsprechend gewünschte Reinluftmenge zum Umspülen der OP-Bestecke freisetzen. Of course, this device can also be built into the operating table and at the same time release a correspondingly desired amount of clean air to rinse the operating utensils.
