Description

Die Erfindung betrifft ein Regenerations- und Krankenhaubett zur Behandlung von Patienten und Erholungsbedürftigen und ein Verfahren zur Kontrolle der Atmosphäre in einem Regenerations - und Krankenhausbett.The invention relates to a regeneration and hospital bed for the treatment of patients and those in need of relaxation and a method of controlling the atmosphere in a regeneration and hospital bed.

Bekannt sind Krankenhausbetten, bei denen die den Patienten umgebende Atmosphäre mit bestimmten Gasen, inbesondere mit Sauerstoff angereichert werden sollen. Es ist auch bekannt, in geschlossenen Zelten oder Räumen, so auch in Brutkästen für Neugeborene, Atmosphären gewünschter Zusammensetzung und Temperatur, insbesondere eine keimfreie Atmosphäre aufrechtzuerhalten. Die dazu verwendeten Gasgemische werden über Versorgungsleitungen, nach Bedarf filtriert, eingeführt und auf der entgegengesetzten Seite abgezogen, so daß Strömungen mit unkontrollierbaren Wirbelbildungen entstehen, die partielle Änderungen des Gasdrucks der Komponenten der Atmosphäre und deren Flüssigkeitsgehalt, vor allem aber unerwünschte Abkühlung und Austrocknung am Körper des Patienten hervorrufen. Hospital beds are known in which the Atmosphere surrounding patients with certain gases, in particular to be enriched with oxygen. It is also known to be in closed tents or Rooms, including in incubators for newborns, atmospheres desired composition and temperature, especially to maintain a sterile atmosphere. The gas mixtures used for this are via supply lines, filtered as required, inserted and subtracted on the opposite side, so that currents with uncontrollable vortex formation arise, the partial changes of the Gas pressure of the components of the atmosphere and their Liquid content, but above all undesirable Cooling and dehydration on the patient's body cause.

Derartige Krankenhausbetten sind insbesondere aus der Französischen Patentanmeldung FR 2 226 980 bekannt, wobei Frischgas aus einem Speicherraum über eine Filterwand in ein Zelt eingeleitet wird, das einen Patienten umgibt. Dabei wird eine kontrollierte, völlig beruhigte Atmosphäre mit konstanter Zusammensetzung in der Umgebung des Patienten jedoch weder angestrebt noch ermöglicht. Such hospital beds are especially from the French Patent application FR 2 226 980 known, fresh gas from a storage space is introduced via a filter wall into a tent that surrounds a patient. Here becomes a controlled, completely calm atmosphere with constant Composition in the patient's environment, however, is neither sought nor enables.

Der Erfindung ist die Aufgabe gestellt, in der Umgebung des Patienten oder Regenerationsbedürftigen eine völlig beruhigte Atmsophäre von konstanter, genau kontrollierbarer Zusammensetzung zu schaffen und respirierte Gase und Flüssigkeitskomponenten sofort und ohne Erzeugung spürbarer Strömungen abzuziehen.The invention has for its object in the area of the patient or in need of regeneration completely calmed atmosphere of constant, precisely controllable Creating composition and respected Gases and liquid components immediately and subtract without generating noticeable currents.

Diese Aufgabe wird mit den Merkmalen der nebengeordneten Ansprüche 1 und 11 gelöst.This task is accomplished with the features of the subordinate claims 1 and 11 solved.

Dabei kann das in den äußeren Zeitraum um den eigentlichen Behandlungsraum zugeführte, genau dosierte und temperierte und klimatisierte Gasgemisch über eine Zuführungsleitung unter einer dem Gasumsatz entsprechenden mehr oder minder starken Strömung und unter unvermeidbaren Wirbelbildungen eingepumpt werden. Das den Patienten oder Regenerationsbedürftigen unmittelbar umgebende, den eigentlichen Behandlungsraum bildende Innenzelt aus feinmaschigem Gewebe läßt nur eine Diffusion dieses Gasgemisches zu, so daß das Frischgas ohne spürbare Strömung und Wirbelbildungen in diesen Behandlungsraum übergeht. Durch Absaugen des verbrauchten, insbesondere sauerstoffarmen und feuchtigkeitsangereicherten Abgases wird ein so großer Unterdruck gegenüber dem äußeren Zeltraum aufrechterhalten, daß er eine ruhig fliessende Diffusion in den Behandlungsraum bewirkt. Dadurch wird in diesem ein stets gleicher ruhiger Atmosphärenzustand mit dem erwünschten konstanten Gehalt an Gaskomponenten, Feuchtigkeit und Temperatur aufrechterhalten.This can be in the outer period around the actual treatment room supplied, precisely dosed and tempered and conditioned gas mixture via a supply line under one corresponding to the gas turnover more or less strong current and are pumped in under inevitable eddy formation. The directly to the patient or those in need of regeneration surrounding, forming the actual treatment room Inner tent made of fine-mesh fabric leaves only a diffusion this gas mixture too, so that the fresh gas without noticeable current and vortex formation in these Treatment room merges. By vacuuming the used up especially low-oxygen and moisture-enriched Exhaust gas becomes such a large negative pressure maintain against the outer tent room, that he has a smoothly flowing diffusion into the treatment room causes. This will make this one always the same calm atmosphere with the desired constant content of gas components, Maintain moisture and temperature.

Wenn für die Beatmung eine andere Zusammensetzung der Atmosphäre als für die Behandlung des Körpers erforderlich ist, kann das gesamte Zelt durch eine gasundurchlässige Zwischenwand getrennt werden, die den Hals des Patienten schonend umschließt. Der Kopfteil kann dann für sich mit dem erwünschten Gasgemisch versorgt werden. Ebenso kann dort ein entsprechenden Innenzelt vorgesehen sein, so daß in dem Kopfteil ebenso eine beruhigte Atmosphäre besteht. Dies ist besonders dann notwendig oder zweckmäßig, wenn dem abgetrennten Körperteil Medikamente in Gasform oder als Aerosole zugeführt werden sollen, die als Komponenten der Atemluft unverträglich oder störend wären.If a different composition for ventilation of the atmosphere than for the treatment of the body the entire tent can be covered by a gas-impermeable partition that can be separated gently encloses the patient's neck. The Headboard can then do with the desired one Gas mixture can be supplied. There can also be a corresponding inner tent may be provided so that in the headboard also has a calm atmosphere. This is particularly necessary or useful if the severed body part medication in gaseous form or to be supplied as aerosols as components of the breathing air incompatible or disruptive would be.

Das erfindungsgemäße Bett kann vorteilhaft für Regenerationsbedürftige, zum Beispiel durch Umweltverschmutzung Geschädigte oder Erschöpfte, Verwendung finden, die einen Schlaf oder einen längeren Aufenthalt in einer optimal zusammengesetzten reinen Atemluft benötigen. Es ist jedoch besonders geeignet für die Behebung von Asthmaerscheinungen, Höhenkrankheit, Atemwegsvergiftungen, vor allem aber als Bett für die Brandwundenbehandlung, wobei die brandverletzten Flächen völlig offen einer entsprechend warmen, die notwendige Feuchtigkeit enthaltenden, absolut keimfreien Atmosphäre ausgesetzt werden können, der die erforderlichen Medikamente in Gasform oder als Aerosol zugesetzt werden und wobei jede Wärmeentzug und Austrocknung verursachende Luftströmung vermieden wird. Die Bettung des Patienten kann dabei in jeder erforderlichen Weise erfolgen. Eine weitere Verwendung ist die Zuführung von Sauerstoff oder von in der Gasphase oder in Aerosolen vorliegenden Medikamenten zur Haut des Patienten. Schließlich ist es möglich, einen erwünschten Luftdruck im Innenzelt aufrechtzuerhalten.The bed according to the invention can be advantageous for those in need of regeneration, for example through pollution Damaged or exhausted, use find a sleep or a long stay in an optimally composed pure breathing air need. However, it is particularly suitable for that Correction of asthma symptoms, altitude sickness, Respiratory poisoning, but especially as a bed for the burn treatment, the burn injured Surfaces completely open to a correspondingly warm one absolutely moisture-free, absolutely germ-free Atmosphere can be exposed to the required Medicines in gaseous form or as an aerosol be added and taking away any heat and dehydration causing air flow is avoided. The patient's bedding can be required in any way Way. Another use is the supply of oxygen or in the Gas phase or drugs present in aerosols to the patient's skin. Finally, it is possible maintain a desired air pressure in the inner tent.

Die Regelung und Steuerung der Zuführung der Behandlungsatmosphäre, die Dosierung ihrer Komponenten, ihres Feuchtigkeitsgehaltes und ihrer Temperierung erfolgt in einer Versorgungseinheit elektronisch, desgleichen die Steuerung des Abzuges der verbrauchten Außenluft mit den notwendigen zeitlichen Variationen, so daß eine relativ geringe Anforderung an die Wartung der Patienten gegeben ist.The regulation and control of the supply of the treatment atmosphere, the dosage of their components, their moisture content and their tempering takes place electronically in a supply unit, likewise the control of the deduction of the used Outside air with the necessary temporal variations, so that a relatively low maintenance requirement the patient is given.

Das in Fig.1 dargestellte Bett weist Bettpfosten in Form von Gleitstangen 1 auf, die an ihren Enden Kugeln 2 aufweisen. An diesen Gleitstangen 1 ist ein Doppelzelt 3 in an den Gleitstangen 1 laufenden Ringen 4 senkrecht verschiebbar. Das Doppelzelt 3 besteht aus einem größeren Außenzelt 5 aus flexiblem, im wesentlichen gasundurchlässigem Material und einem kleineren, von dem Außenzelt 5 umgebenen Innenzelt 6 aus flexiblem, für Gase diffusionsdurchlässigem Material. Beide Zelte 5 und 6 haben die Form eines Walmdaches, das nach dem Fußende des Bettes zu in seiner Höhe abfällt. Das Außenzelt 5 ist an seinem First von einem Stab 7 verstärkt, an dem es mit einer Aufhängevorrichtung 8 höhenverstellbar mit Leinen 9 verbunden ist. In gleicher Weise sind die unteren Ränder des Außenzeltes 5 mit weiteren Stäben 10, 11, 12, 13 verstärkt. Diese Stäbe sind in abgenähte Laschen des Zeltmaterials geschoben und an den Ecken 14, 15, 16, 17 des Außenzeltes 5 mit Ringen 4 verbunden, die an den Gleitstäben 1 gleiten können. Über die Stäbe 10 bis 13 steht das Material des Außenzeltes 5 um einen 10 bis 20cm breiten Streifen 18 über und ist an seinem unteren Saum an jeder der vier Seiten mit einem mit Metallschrot gefüllten Beschwerungskabel 19 versehen, durch dessen Gewicht dieser Streifen 18 an die Kante des Rahmens 20 des Bettes angedrückt wird und so das Außenzelt 5 am Bett gegen die Außenatmosphäre abdichten kann. Diese Abdichtung kann durch an dieser Kante umlaufende Wülste 21 aus elastisch verformbaren, relativ weichen Kunststoff verbessert werden, wie dies Fig.3 bei 21 zeigt.The bed shown in Fig.1 has bed posts in Form of slide rods 1 on which balls at their ends 2 have. There is a double tent on these sliding poles 1 3 in rings running on the slide rods 1 4 vertically movable. The double tent 3 exists from a larger outer tent 5 made of flexible, in essential gas impermeable material and a smaller inner tent surrounded by the outer tent 5 6 made of flexible, permeable to gases Material. Both tents 5 and 6 have the shape of a Hipped roofs that come in after the foot of the bed its height drops. The outer tent 5 is on his First reinforced by a rod 7, to which it is attached Hanging device 8 adjustable in height with lines 9 is connected. In the same way, the lower ones Edges of the outer tent 5 with further rods 10, 11, 12, 13 reinforced. These rods are in stitched tabs of the tent material and at the corners 14, 15, 16, 17 of the outer tent 5 connected with rings 4, the can slide on the slide rods 1. About the bars 10 to 13 is the material of the outer tent 5 a 10 to 20 cm wide strip 18 over and is on its lower hem on each of the four sides with a weight cable filled with metal shot 19 provided by the weight of this strip 18 pressed against the edge of the frame 20 of the bed and so the outer tent 5 on the bed against the Can seal the outside atmosphere. This seal can by beads 21 running around this edge elastically deformable, relatively soft plastic be improved, as shown in FIG. 3 at 21.

Das Innenzelt 6 ist an seinen Unterkanten mit den Stäben 10 bis 13 und damit mit dem Außenzelt 5 verbunden und somit ebenso versteift wie dieses. Es weist ebenfalls eine walmdachartige Form mit nach dem Fußende abfallendem First auf, der durch einen Stab 22 verstärkt ist. Der Stab 22 ist mit Leinen 23 und 24 am Stab 7 des Firstes des Außenzeltes 5 verbunden und straff gehalten.The inner tent 6 is on its lower edges with the Poles 10 to 13 and thus with the outer tent 5 connected and thus stiffened like this. It also shows a hipped roof-like shape at the foot of the sloping ridge, which is covered by a Rod 22 is reinforced. The rod 22 is with linen 23 and 24 on pole 7 of the ridge of the outer tent 5 connected and kept tight.

Das Innenzelt 6 ist kleiner als das Außenzelt 5. Zwischen beiden ergibt sich somit ein Raum 25, der gegenüber der Außenstmosphäre durch das gasundurchlässige Material des Außenzeltes 5 gasdicht abgeschlossen ist, gegenüber dem Innenzelt jedoch für eine Gasdiffusion offen ist. Das Innenzelt 6 ist so groß, daß ein Patient gut darin liegen und sich aufsetzen kann.The inner tent 6 is smaller than the outer tent 5. A space 25 thus results between the two to the outside atmosphere through the gas impermeable Material of the outer tent 5 sealed gas-tight compared to the inner tent for gas diffusion is open. The inner tent 6 is like this great that a patient should lie in it well can touch down.

Das Außenzelt 5 weist an seiner fußseitigen Wand eine Öffnung 26 auf, in die ein flexibler weiter Schlauch 27 mündet, der den Raum 25 zwischen Innen- und Außenzelt 6, 5 mit einer Versorgungseinheit 28 verbindet, über die frisches Atmungsgas in den Raum 25 mit einem Überdruck gegenüber der Außenatmosphäre gepumpt werden kann.The outer tent 5 has a on its foot wall Opening 26 into which a flexible wide hose 27 opens out, the space 25 between inside and Outer tent 6, 5 connects to a supply unit 28, over the fresh breathing gas into room 25 with an overpressure compared to the outside atmosphere can be pumped.

Zwischen dem Rand des Rahmens 20 des Bettes und seiner Matratze 29 ist ein Streifen 30 freigelassen, in dem in gleichmäßigen Abständen Abzugsrohre 31 münden, die zu nicht dargestellten Sammelrohren an der Unterseite des Bettes führen, die wiederum mit einem flexiblen Schlauch 33 mit einer Saugpumpe der Versorgungseinheit 28 verbunden sind. Die Einrichtung der verschiebbaren Versorgungseinheit und die erforderlichen elektronischen Steuerungsschaltungen sind an sich bekannt und brauchen daher nicht näher beschrieben zu werden. Es muß jedoch im Raum 25 ein höherer Druck in dem von der Versorgungseinheit 28 gemischten und bereitsgestellten Gas gegenüber der Außenatmosphäre und gegenüber dem Innenraum des Innenzeltes 6 aufrechterhalten werden. Im Innenzelt 6 muß dabei immer noch ein gewisser Überdruck gegenüber der Außenatmosphäre vorhanden sein, der ein Eindringen von Außenluft durch Undichtigkeiten des unteren Verschlusses des Außenzeltes 5 verhindert. Während nun im Raum 25 durch das Einblasen des Frischgases turbulente Verhältnisse mit Luftströmungen herrschen, die vom Patienten ferngehalten werden sollen, besteht im Innenzelt 6 eine völlig beruhigte strömungsfreie Atmosphäre, die auch durch das gesteuerte Absaugen der verbrauchten Luft nicht gestört wird, da eine Vielzahl von rings verteilten Abzugsrohren 31 vorgesehen ist. Das Innenzelt 6 besteht aus einem feinporigen Gewebe, das nur ein Diffundieren des Gases aus dem Raum 25 zuläßt, das jedoch aus einem leicht zu reinigendem und zu desinfizierendem Material bestehen muß, beispielsweise aus einem Gewebe aus feinen Kunststoffdrähten mit glatter Oberfläche. Es ist ferner zweckmäßig, daß das Material des Außenzeltes wenigstens teilweise aus einer durchsichtigen Folie besteht und auch das Innenzelt 6 wenigstens auf seiner dem Kopfende des Bettes zugewandten Seite ein ausreichend großes Fenster aufweist, um eine Beobachtung des Patienten zu ermöglichen und um andererseits für diesen eine psychische Belastung zu vermeiden.Between the edge of the frame 20 of the bed and his Mattress 29 has a strip 30 left in it outlet pipes 31 open at regular intervals, the manifolds, not shown, on the underside of the bed, which in turn with a flexible hose 33 with a suction pump of the supply unit 28 are connected. The facility the sliding supply unit and the required electronic control circuits are known per se and therefore do not need to be described in more detail to become. However, it must be in room 25 higher pressure in that from the supply unit 28 mixed and provided gas versus the Outside atmosphere and in relation to the interior of the inner tent 6 are maintained. In the inner tent 6 must still have a certain overpressure the outside atmosphere to be present, which is an intrusion of outside air through leaks of the lower Closure of the outer tent 5 prevented. While now in room 25 by blowing in the fresh gas turbulent conditions with air currents prevail, that should be kept away from the patient in the inner tent 6 a completely calm flow-free Atmosphere, which is also controlled by suction the used air is not disturbed, because one A plurality of exhaust pipes 31 distributed around the ring are provided is. The inner tent 6 consists of a fine-pored Tissue that is just diffusing the gas from room 25, but from a light to be cleaned and disinfected material must, for example from a fabric of fine Plastic wires with a smooth surface. It is further expedient that the material of the outer tent at least partly from a transparent film exists and also the inner tent 6 at least on it a sufficient side facing the head of the bed has large window to an observation of the patient and on the other hand for to avoid psychological stress.

Das in Fig.4 schematisch dargestellte Bett weist feststehende Stirn- und Fußenden auf, wobei die Fußwand 32 aus massivem undurchsichtigem Material bestehen kann, die Stirnwand 33 aber durchsichtig ist, um den Patienten beobachten zu können und diesen nicht im Dunklen zu lassen. Das Innenzelt 34 ist unterteilt in ein Körperteil 35 und ein Kopfteil 36. Beide Teile sind auf tonnenförmige Rahmen 37 und 38 aufgespannt, wobei der Rahmen 37 für das Körperteil 35 zwei Zwischenrippen 39 aufweist. An seinem höchsten Bereich ist am Innenzelt 34 eine an der Fußwand 32 und an der Stirnwand 33 befestigte Schiene 40 vorgestehen, an der Gelenke 41 für die aufklappbare Vorderseite 42 des Körperteil 35 und Gelenke 42 für die getrennt aufklappbare Vorderseite 43 des Kopfteils 36 vorgesehen sind.The bed shown schematically in Figure 4 has fixed forehead and foot ends, with the foot wall 32 consist of solid opaque material can, but the end wall 33 is transparent to the To be able to observe patients and not in the To leave dark. The inner tent 34 is divided into a body part 35 and a head part 36. Both parts are mounted on barrel-shaped frames 37 and 38, the frame 37 for the body part 35 two Has intermediate ribs 39.
