BestrahlungsliegeRadiation couch
Die Erfindung betrifft eine Bestrahlungsliege mit einer " strahlungsdurchlässigen Liegefläche zur Aufnahme einer zu bestrahlenden Person und mit unter der Liegefläche ange¬ ordneten Bestrahlungsquellen.The invention relates to an irradiation couch with a " radiation-permeable lying surface for receiving a person to be irradiated and with radiation sources arranged under the lying surface.
Bei bekannten Bestrahlungsliegen dieser Art (DE 30 85 487 AI) ist die Liegefläche als eine glatte, leicht gewölbte Acrylglasplatte ausgebildet, auf welcher die zu bestrah¬ lende Person unmittelbar Platz nimmt, so daß deren Haut unmittelbar großflächig mit der Acrylglasoberfl che in Be¬ rührung kommt. Zwar werden die unter der Liegefläche ange¬ ordneten Bestrahlungsquellen durch strömende Kühlluft ge¬ kühlt, jedoch kann dies in der Regel nicht dazu führen, daß auch die Acrylglasplatte eine Temperatur annimmt, wel¬ che von der zu bestrahlenden Person als angenehm empfunden wird. Vielmehr wird auf der Oberseite der Bestrahlungs¬ liege in der Regel lediglich eine solche Temperatur er¬ reicht, welche oberhalb normaler Körpertemperatur liegt und zu Feuchtigkeitsausbruch an der Haut der bestrahlten Person führt.In known radiation couches of this type (DE 30 85 487 AI), the lying surface is designed as a smooth, slightly curved acrylic glass plate on which the person to be irradiated immediately takes a seat, so that his skin immediately comes into contact with the acrylic glass surface over a large area is coming. Although the radiation sources arranged under the lying surface are cooled by flowing cooling air, this cannot generally result in the acrylic glass plate also assuming a temperature which the person to be irradiated perceives as pleasant. Rather, the temperature on the upper side of the radiation bed is usually only that which is above normal body temperature and leads to a breakout of moisture on the skin of the irradiated person.
Es ist Aufgabe der Erfindung, eine gattungsgemäße Bestrah¬ lungsliege so auszubilden, daß die der Liegefläche zuge¬ wandte Seite der zu bestrahlenden Person eine als angenehm empfundene Kühlung erfährt, durch welche Feuchtigkeitsaus¬ brüche auf der Haut verhindert sind. Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß auf der Liegefläche Erhebungen und dazwischen liegende Vertie¬ fungen ausgebildet sind, und die zu bestrahlende Person auf den Erhebungen aufruht, und daß in die Vertiefungen zwischen den Erhebungen Kühlluft einführbar ist, welche die Haut der auf den Erhebungen aufruhenden Person direkt von unten kühlt.It is an object of the invention to design a radiation bed of the generic type in such a way that the side of the person to be irradiated facing the lying surface experiences a cooling which is perceived as pleasant, by means of which moisture outbreaks on the skin are prevented. The object is achieved in that elevations and recesses lying in between are formed on the lying surface, and the person to be irradiated rests on the elevations, and that cooling air can be introduced into the depressions between the elevations, which is the skin of the on the elevations cooling person directly from below.

Die Fig. 1 zeigt in schaubildlicher, teilweise aufgebro¬ chener Darstellung eine herkömmliche Bestrahlungsliege 1 mit einer nach oben gerichteten Liegefläche 2, auf welcher eine zu bestrahlende Person, gewöhnlich auf dem Rücken liegend, Platz nimmt. Die Liegefläche 2 ist von einem Untergestell 3 abgestützt und umfaßt eine UV-strahlen¬ durchlässige Acrylglasplatte 4 (vgl. auch Fig. 2) mit darunter angeordneten, in Längsrichtung der Bestrahlungs¬ liege 1 verlaufenden Bestrahlungsquellen 5 in Gestalt stabförmiger Bestrahlungslampen, welche z.B. bräunende UV-Strahlung nach oben durch die Arcrylglasplatte 4 hindurch zum Körper der zu bestrahlenden Person hin ab¬ geben. Die Bestrahlungsquellen 5 sind in einem auf dem Untergestell 3 aufruhenden Gehäuse 7 untergebracht, das oben von der Acrylglasplatte 4 abgedeckt ist. Durch das Gehäuse 7 wird in an sich bekannter Weise Kühlluft ge¬ führt, welche die Bestrahlungsquellen 5 kühlt. Da die Tem¬ peratur dieser Kühlluft im Hinblick auf die ideale Be¬ triebstemperatur der die Bestrahlungsquellen 5 bildenden Bestrahlungslampen einen bestimmten Wert nicht unter¬ schreiten darf, kann die Acrylglasplatte 4 in der Regel nur auf eine Temperatur gebracht werden, die von der zu bestrahlenden Person noch als zu warm und unangenehm empfunden wird und zu Feuchtigkeitsausbrüchen sowie einem leichten Kleben der Haut an der Oberfläche der Acrylglas¬ platte 4 führen kann. Wie aus Fig. 1 und 2 hervorgeht, sind daher mit der Ober¬ fläche der Arcrylglasplatte 4 Erhebungen in Gestalt in Längsrichtung der Bestrahlungsliege 1 verlaufender U-för- miger Leisten 8 fest und abgedichtet verbunden, die an ihrer in Fig. 1 und 2 links gelegenen Stirnseite geschlos¬ sen sind. An ihrer in Fig. 1 und 2 rechts gelegenen Stirn¬ seiten sind die U-förmigen Leisten 8 offen und münden in einen gegenüber dem Gehäuse 7 geschlossenen Verteiler 9, in den, wie in Fig. 1 und 2 durch den Pfeil A dargestellt, ein besonderer Kühlluftstrom einführbar ist. Dieser Kühl- luftstrom ist von dem Luftstrom, der die Bestrahlungsquel¬ len 5 kühlt, unabhängig und hat eine Temperatur, die ge¬ ringer als der die Bestrahlungsquelle kühlende Luftstrom ist. Beispielsweise kann die Temperatur der Kühlluft im Verteiler 9 etwa 35 bis 37° C betragen.1 shows a diagrammatic, partially broken-open representation of a conventional radiation bed 1 with an upward lying surface 2, on which a person to be irradiated, usually lying on his back, takes a seat. The lying surface 2 is supported by a base frame 3 and comprises a UV-transparent transparent acrylic glass plate 4 (cf. also FIG. 2) with radiation sources 5 arranged underneath and running in the longitudinal direction of the radiation bed 1 in the form of rod-shaped radiation lamps, which, for example, tanning UV - Give up radiation through the acrylic glass plate 4 to the body of the person to be irradiated. The radiation sources 5 are accommodated in a housing 7 resting on the base frame 3, which is covered at the top by the acrylic glass plate 4. Cooling air, which cools the radiation sources 5, is passed through the housing 7 in a manner known per se. Since the temperature of this cooling air must not fall below a certain value in view of the ideal operating temperature of the radiation lamps forming the radiation sources 5, the acrylic glass plate 4 can generally only be brought to a temperature which is to be determined by the person to be irradiated is still perceived as too warm and uncomfortable and can lead to outbreaks of moisture and a slight sticking of the skin to the surface of the acrylic glass plate 4. As can be seen from FIGS. 1 and 2, elevations in the form of U-shaped strips 8 extending in the longitudinal direction of the radiation bed 1 are fixed and sealed to the surface of the acrylic glass plate 4, which are on the left in FIGS. 1 and 2 located front side are closed. 1 and 2, the U-shaped strips 8 are open and open into a distributor 9 which is closed with respect to the housing 7 and into which, as shown by the arrow A in FIGS. 1 and 2, a special cooling air flow can be introduced. This cooling air flow is independent of the air flow that cools the radiation sources 5 and has a temperature that is lower than the air flow that cools the radiation source. For example, the temperature of the cooling air in the distributor 9 can be approximately 35 to 37 ° C.
Die U-förmigen Leisten 8 weisen seitliche Öffnungen 11 auf, welche in Vertiefungen 12 ausmünden, die zwischen den in gegenseitigen Abständen angeordneten Leisten 8 ausge¬ bildet sind. Die zu bestrahlende Person ruht auf der Ober¬ fläche der stabförmigen Leisten 8 auf, so daß ihre Haut unmittelbar mit der Kühlluft in den Vertiefungen 12 in Be¬ rührung gelangt und die zu bestrahlende Person hierdurch einen als angenehme empfundenen Kühleffekt erfährt.The U-shaped strips 8 have lateral openings 11 which open into recesses 12 which are formed between the strips 8 arranged at mutual intervals. The person to be irradiated rests on the surface of the rod-shaped strips 8 so that their skin comes into direct contact with the cooling air in the depressions 12 and the person to be irradiated thereby experiences a cooling effect which is perceived as pleasant.
Der aus dem Verteiler 9 in die U-förmigen Leisten 8 einge¬ führte und aus den Öffnungen 11 austretende Kühlluftstrom stammt von einer herkömmlichen (nicht dargestellten) Kühl¬ luftquelle, beispielsweise einem Gebläse mit vorgeschalte¬ tem Heiz- oder Kühlaggregat, das eine Einstellung der Kühllufttemperatur gestattet. Die Kühlluft zur Kühlung der Bestrahlungsquellen 5 stammt aus einer separaten Kühl¬ quelle, beispielsweise einem einfachen Luftgebläse, das mit Umgebungsluft gespeist wird.The cooling air flow introduced from the distributor 9 into the U-shaped strips 8 and exiting from the openings 11 comes from a conventional (not shown) cooling air source, for example a blower with an upstream heating or cooling unit which adjusts the Cooling air temperature allowed. The cooling air for cooling the radiation sources 5 comes from a separate cooling source, for example a simple air blower, which is fed with ambient air.
Die U-förmigen Leisten 8 bestehen ebenfalls aus einem strahlendurchlässigen Werkstoff, beispielsweise Acrylglas, so daß die aus den Bestrahlungsquellen 5 austretende Strahlung zur Haut der auf der Oberfläche der Leisten 8 aufruhenden Person gelangt.The U-shaped strips 8 likewise consist of a radiation-permeable material, for example acrylic glass, so that the radiation emerging from the radiation sources 5 reaches the skin of the person resting on the surface of the strips 8.
Die Fig. 3 zeigt eine gegenüber Fig. 1 und 2 abgewandelte Ausführungsform der Liegefläche 2 einer Bestrahlungsliege, bei welcher auf der Acrylglasplatte 4, welche sich über den Bestrahlungsquellen 5 befindet, eine wellenförmig aus¬ gebildete Platte aus ebenfalls strahlendurchlässigem Mate¬ rial, beispielsweise Acrylglas, angeordnet ist. Die Sei¬ tenflächen der wellenförmigen Erhebungen sind mit seit¬ lichen Öffnungen 21 versehen, aus denen Kühlluft ge¬ wünschter Temperatur in die "Wellentäler" zwischen den "Wellenbergen" austritt. Die zu bestrahlende Person liegt auf den Scheiteln der Wellenberge auf und wird von der in den Wellentälern strömenden Kühlluft von unten her direkt gekühlt.FIG. 3 shows an embodiment of the lying surface 2 of an irradiation couch modified in comparison with FIGS. 1 and 2, in which a wave-shaped plate made of likewise radiation-transmissive material, for example acrylic glass, is formed on the acrylic glass plate 4, which is located above the radiation sources 5 , is arranged. The side surfaces of the wave-shaped elevations are provided with lateral openings 21, from which cooling air of the desired temperature exits into the "wave valleys" between the "wave crests". The person to be irradiated lies on the top of the wave crests and is cooled directly from below by the cooling air flowing in the wave valleys.
Bei der Bestrahlungsliege nach Fig. 4 ist eine Liegefläche 22 auf einem Untergestell 23 angeordnet. Die Liegefläche 22 umfaßt eine strahlendurchlässige Platte 24, z.B. aus Acrylglas, unter welcher stabförmige Bestrahlungslampen 25 angeordnet sind. Mit der Platte 24 sind einstückig und aus dem gleichen Werkstoff bestehend U-förmige Leisten 26 in gegenseitigen Abständen verbunden, so daß sich in Längs¬ richtung der Bestrahlungsliege verlaufende Kanäle 27 ergeben, deren in Fig. 4 links liegenden Stirnseiten ge¬ schlossen sind. An den Oberflächen der Leisten 26 sind nach oben vorstehende, in Längsrichtung der Liege verlau¬ fende Stege 28 ausgebildet, zwischen denen Vertiefungen angeordnet sind, deren Boden jeweils von der oberen Begrenzung der Kanäle 27 gebildet ist. In diesen Böden sind durchgehende Öffnungen 29 ausgebildet. An ihrer in Fig. 4 rechts gelegenen Stirnseite stehen die Kanäle 27 mit einem Verteiler 31 in Verbindung, in den, wie durch den Pfeil B angedeutet, Kühlluft gewünschter Temperatur einführbar ist. Die Kühlluft durchströmt die Kanäle 27, tritt aus den Öffnungen 29 aus und kühlt somit unmittelbar die Haut der auf den Stegen 28 aufruhenden, zu bestrahlen¬ den Person.4, a lying surface 22 is arranged on a base frame 23. The lying surface 22 comprises a radiolucent plate 24, for example made of acrylic glass, under which rod-shaped radiation lamps 25 are arranged. U-shaped strips 26 made of the same material are connected to the plate 24 in one piece and at mutual intervals, so that there are channels 27 running in the longitudinal direction of the radiation bed, the end faces of which are left in FIG. 4 being closed. Are on the surfaces of the strips 26 upwardly projecting webs 28 extending in the longitudinal direction of the bed, between which recesses are arranged, the bottom of each of which is formed by the upper boundary of the channels 27. Through openings 29 are formed in these bottoms. On their right-hand end in FIG. 4, the channels 27 are connected to a distributor 31, into which, as indicated by the arrow B, cooling air of the desired temperature can be introduced. The cooling air flows through the channels 27, emerges from the openings 29 and thus directly cools the skin of the person to be irradiated resting on the webs 28.
Die Fig. 5 zeigt eine gegenüber Fig. 4 insofern abgewan¬ delte Ausführungsform, als eine Liegefläche 32 nicht als einstückige, profilierte Platte aus strahlendurchlässigem Werkstoff ausgebildet ist. Eine Platte 34, beispielsweise wiederum aus Acrylglas, überdeckt stabförmige Bestrah¬ lungslampen 35. Über Stege 36 ist auf der Oberseite der Platte 34 eine weitere strahlendurchlässige Platte 37 im Abstand abgestützt, die in Längsrichtung der Bestrahlungs¬ liege verlaufende, nach oben abstehende Stege 38 aufweist. Auf diesen Stegen ruht die zu bestrahlende Person auf. Zwischen den Stegen 38 sind Vertiefungen ausgebildet, deren Boden mit durchgehenden Öffnungen 39 versehen ist. Die Platte 34, die Stege 36 und die Platte 37 vermitteln Kanäle 41, die den Kanälen 27 in Fig. 4 entsprechen, also von Kühlluft durchströmt sind. Somit tritt aus den Öffnun¬ gen 39, die mit den Kanälen 41 in Verbindung sind, Kühl¬ luft aus und kühlt direkt die Haut der auf den Stegen 38 aufliegenden Person.FIG. 5 shows an embodiment modified compared to FIG. 4 in that a lying surface 32 is not designed as a one-piece, profiled plate made of radiation-permeable material. A plate 34, for example again made of acrylic glass, covers rod-shaped irradiation lamps 35. A further radiolucent plate 37 is supported at a distance via webs 36 on the top of the plate 34, said plate 37 having webs 38 projecting upwards in the longitudinal direction of the radiation bed . The person to be irradiated rests on these bridges. Wells are formed between the webs 38, the bottom of which is provided with through openings 39. The plate 34, the webs 36 and the plate 37 mediate channels 41 which correspond to the channels 27 in FIG. 4, that is to say through which cooling air flows. Cooling air thus emerges from the openings 39, which are connected to the channels 41, and directly cools the skin of the person lying on the webs 38.
In Fig. 6 wird eine Liegefläche 42 von einer strahlen- durchlässigen Platte 43 gebildet, die ein rechteckiges Wellenprofil aufweist. Die Wellenberge werden dabei von längs verlaufenden, in gegenseitigen Abständen angeordne¬ ten Rippen oder Leisten 44 mit Rechteckprofil gebildet, zwischen denen sich Vertiefungen 45 befinden. Im Kopf- oder Fußbereich der Bestrahlungsliege ist die in der be¬ schriebenen Weise profilierte Platte 43 von einer weiteren strahlendurchlässigen Platte 46 abgedeckt, die auf den Rippen oder Leisten 44 dicht aufliegt. Die Vertiefungen 45 bilden in Längsrichtung der Liege verlaufende Kanäle, die (in nicht dargestellter Weise) mit einem Verteiler 47 ver¬ bunden sind. Der Verteiler 47 ist an eine Saugquelle ange¬ schlossen, so daß durch die Vertiefungen 45 Kühlluft, bei¬ spielsweise Umgebungsluft gesaugt wird. Eine zu bestrah¬ lende Person, welche außerhalb der Platte 46 unmittelbar auf den Oberseiten der Rippen oder Leisten 44 aufliegt und die Vertiefungen 45 nach oben hin abdeckt, wird somit un¬ mittelbar durch die durch diese Vertiefungen 45 abgesaugte Luft gekühlt.6, a lying surface 42 is covered by a radiation permeable plate 43 is formed, which has a rectangular wave profile. The wave crests are formed by longitudinal ribs or strips 44 with a rectangular profile, spaced apart from one another, between which there are depressions 45. In the head or foot region of the radiation bed, the plate 43 profiled in the manner described is covered by a further radiolucent plate 46, which lies tightly on the ribs or strips 44. The depressions 45 form channels running in the longitudinal direction of the bed which are connected (in a manner not shown) to a distributor 47. The distributor 47 is connected to a suction source, so that cooling air, for example ambient air, is sucked through the depressions 45. A person to be irradiated, who rests directly on the upper sides of the ribs or strips 44 outside the plate 46 and covers the recesses 45 upwards, is thus cooled directly by the air sucked through these recesses 45.
Statt die Luft bei der Ausführungsform gemäß Fig .6 in Richtung der dargestellten Pfeile abzusaugen, könnte die Kühlluft auch in umgekehrter Richtung durch die von den Vertiefungen 45 gebildeten Kanäle hindurchgeblasen werden. Am Kühleffekt würde sich hierdurch nichts ändern.Instead of sucking off the air in the direction of the arrows shown in the embodiment according to FIG. 6, the cooling air could also be blown through the channels formed by the depressions 45 in the opposite direction. This would not change the cooling effect.
Die Ausführungsform nach Fig. 7 unterscheidet sich von den bisher beschriebenen Ausführungsformen lediglich dadurch, daß die von Leisten gebildeten Erhebungen 51 und die da¬ zwischen liegenden Vertiefungen 52 nicht in Längs-, son¬ dern in Querrichtung der Bestrahlungsliege verlaufen. Die Kühlluft tritt aus Öffnungen 53 in den Seitenwänden der Erhebungen 51 in die Vertiefungen 52 aus und kühlt von da aus direkt von unten die Haut einer auf den Erhebungen 51 aufruhenden Person. Der Innenraum der Erhebungen 51 steht mit einem Kühlluftverteiler in Verbindung.The embodiment according to FIG. 7 differs from the previously described embodiments only in that the elevations 51 formed by strips and the recesses 52 therebetween do not run in the longitudinal direction but rather in the transverse direction of the radiation bed. The cooling air emerges from openings 53 in the side walls of the elevations 51 into the depressions 52 and from there cools the skin of a person resting on the elevations 51 directly from below. The interior of the elevations 51 is connected to a cooling air distributor.
Bei der Ausführungsform gemäß Fig. 8 sind Erhebungen als flächig auf einer Liegefläche 62 angeordneten Noppen 63 ausgebildet, auf denen die zu bestrahlende Person Platz nimmt. In den Vertiefungen zwischen den Noppen 63 sind Öffnungen 64 ausgebildet, aus denen Kühlluft in Richtung der Pfeile C austritt.In the embodiment according to FIG. 8, elevations are formed as knobs 63 arranged flat on a lying surface 62, on which the person to be irradiated takes a seat. Openings 64 are formed in the recesses between the knobs 63, from which cooling air emerges in the direction of the arrows C.
Wie dargestellt, sind die Noppen 63 auf einer Strahlen- durchlässigen Platte 65 ausgebildet, die über Stege 66 auf einer weiteren, strahlendurchlässigen Platte 67 in der Weise abgestützt ist, daß zwischen den Stegen 66 Kanäle entstehen, durch die Kühlluft in Richtung des Pfeiles D strömt. Diese Kühlluft tritt durch die Öffnungen 64 aus. Im übrigen funktionieren die Ausführungsformen gemäß Fig. 7 und 8 genauso wie die Ausführungsformen gemäß Fig. 1 bis 6.As shown, the knobs 63 are formed on a radiolucent plate 65, which is supported by webs 66 on a further, radiolucent plate 67 in such a way that channels are formed between the webs 66, through which cooling air flows in the direction of arrow D. . This cooling air exits through the openings 64. Otherwise, the embodiments according to FIGS. 7 and 8 function in exactly the same way as the embodiments according to FIGS. 1 to 6.
In Fig. 1 bis 7 verlaufenden die Erhebungen, auf denen die zu bestrahlende Person aufruht, geradlinig. Die Erhebungen könnten jedoch auch in der Ebene der Liegefläche gekrümmt verlaufen. In Fig. 1 to 7, the elevations on which the person to be irradiated rests are straight. However, the elevations could also be curved in the plane of the lying surface.
