Description
Die Erfindung betrifft eine Vorrichtung zur lokalen Kondensatvermeidung im gasdurchströmten System eines Insufflators, Beatmungs- oder Atemtherapiegerätes durch die Beheizung von gasleitenden Bauelementen. Eine solche Vorrichtung wird im nachfolgenden Text auch als „Heizelement" bezeichnet.The The invention relates to a device for local condensate avoidance in the gas-flow system an insufflator, ventilator or respiratory therapy device the heating of gas-conducting components. Such a device is referred to in the following text as "heating element".
Soweit im Rahmen dieses Schutzrechtes von gasleitenden Bauelementen die Rede ist, werden hierunter insbesondere Messeinrichtungen, Ventile und Filter verstanden, ausdrücklich nicht jedoch beheizte Beatmungsschläuche.So far within the scope of this protective right of gas-conducting components the Speech is, are hereunder in particular measuring equipment, valves and filters understood, expressly but not heated breathing tubes.
Stand der TechnikState of the art
Im Rahmen der Befeuchtung von medizinischen Gasen zum Zweck der Atemtherapie/Beatmung oder Insufflation kommt es immer wieder zu Problemen im Zusammenhang mit der Bildung von Kondensat an feuchtigkeitsempfindlichen Stellen im gasdurchströmten System. Zu diesen gehören beispielsweise Messeinrichtungen, Ventile und Filter. Für wesentliche Anteile des gasdurchströmten Systems sind geeignete Lösungen zur Kondensatvermeidung vorhanden, beispielsweise für Beatmungsschläuche, die zu diesem Zwecke beheizt ausgeführt sein können.in the Frame of humidification of medical gases for the purpose of respiratory therapy / ventilation or insufflation, it always comes back to problems related with the formation of condensate at moisture-sensitive sites in the gas flowed through System. Belong to these for example, measuring equipment, valves and filters. For essential Shares of the gas flowed through Systems are suitable solutions For condensate avoidance available, for example, for ventilation hoses, the be executed heated for this purpose can.
Allerdings finden sich auch Bereiche, für die es bislang keine zufrieden stellende Lösung gibt. Beispielsweise gibt es viele ältere Beatmungsgeräte, in deren Exspirationsbereich feuchteempfindliche Sensoren zur Messung von Gasstromparametern (z.B. Volumen, Flow, Druck) integriert sind. Die Auskondensation von Feuchte aus dem durchströmenden Gas an diesen Bauelementen kann hier beispielsweise zum Zusetzen von Messöffnungen führen mit der Folge von Störungen und Alarmen des Beatmungsgerätes. Problematisch wird dies vor allem bei der Verwendung von aktiven Atemgasbefeuchtern und beheizten Ausatemschläuchen, da dann der Feuchtegehalt des durchströmenden Ausatemgases besonders hoch ist. Moderne Beatmungsgeräte weisen mitunter eine integrierte Beheizung bzw. geeignete thermische Isolierung dieses Ausatembereiches auf und vermeiden das beschriebene Problem auf diese Weise.Indeed there are also areas for which there is not yet a satisfactory solution. For example there it's a lot of older ones Ventilators, in their expiratory area moisture-sensitive sensors for measurement gas flow parameters (e.g., volume, flow, pressure) are integrated. The condensation of moisture from the gas flowing through these components can lead to clogging of measuring openings, resulting in interference and Alarms of the ventilator. This is particularly problematic when using active Atemgasbefeuchtern and heated Ausatemschläuchen, because then the moisture content the flowing through Exhaled gas is particularly high. Modern ventilators sometimes have an integrated heating or suitable thermal insulation This exhalation on and avoid the problem described in this way.
Problematisch sind auch unbeheizte Bauelemente in der Zuleitung von Gasen zum Patienten, z.B. Bakterienfilter. Kommt es in diesen zur Kondensation, so besteht die Gefahr, dass im zeitlichen Verlauf der Durchflusswiderstand des Filters ansteigt und/oder dessen Filtrationseffizienz beeinträchtigt wird. Außerdem steht auskondensierte Feuchte im zuleitenden Schenkel des pneumatischen Kreislaufs dem Patienten nicht zur Verfügung, wodurch der Wirkungsgrad des Anfeuchters verringert wird.Problematic are also unheated components in the supply of gases to Patients, e.g. Bacterial filter. Does it come to condensation in these, so there is a risk that over time the flow resistance of the filter increases and / or its filtration efficiency is impaired. Furthermore is condensed moisture in the leading leg of the pneumatic Circulation is not available to the patient, reducing the efficiency of the moistener is reduced.
Ein anderer Lösungsansatz sind spezielle Beatmungsschläuche für die Ausatmung, die einen Teil der im Gas enthaltenen Feuchte durch diffusionsfähige Wandmaterialien an die Umgebung abgeben und so die Kondensationseffekte im Ausatembereich der Beatmungsgeräte reduzieren.One another approach are special breathing tubes for the Exhalation, which absorbs some of the moisture contained in the gas through diffusive wall materials give off to the environment and so the condensation effects in the exhalation of the ventilators to reduce.
Ein anderer Lösungsansatz ist die Verwendung unbeheizter Ausatemschläuche in Verbindung mit einer kondensatsammelnden Wasserfalle, wodurch der Feuchtegehalt des Ausatemgases ebenfalls vor Eintritt in den Exspirationsbereich des Beatmungsgerätes reduziert wird.One another approach is the use of unheated exhalation tubes in conjunction with a condensate collecting water trap, whereby the moisture content of the exhaled gas also reduced before entering the expiratory area of the ventilator becomes.
Weitere Lösungsansätze bestehen in Form einer Überhitzung des Ausatemgases vor Eintritt in den Exspirationsbereich des Beatmungsgerätes, wodurch die relative Feuchte ebenfalls reduziert und die Kondensatbildung in diesem Bereich durch allmähliche Aufheizung reduziert wird.Further Solutions exist in the form of overheating the exhalation gas before entering the expiratory area of the ventilator, whereby the relative humidity also reduces and the formation of condensation in this area by gradual Heating is reduced.
Aufgabe der vorliegenden Erfindung ist es, die beschriebenen Probleme auf technisch robuste und zugleich einfach handhabbare Weise zu lösen und dadurch die Betriebsstabilität des Beatmungssystems zu erhöhen.task It is the object of the present invention to address the problems described to solve technically robust and at the same time easy to handle way and thereby the operational stability of the ventilation system.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Vorrichtung zur Beheizung von gasleitenden Bauelementen im gasdurchströmten System eines Insufflators, Beatmungs- oder Atemtherapiegerätes, dadurch gekennzeichnet dass diese eine elektrische Verbindung zu einer vom Beatmungsgerät oder Insufflator unabhängigen Energiequelle aufweist. Diese Vorrichtung wird mit dem zu beheizenden Bauelement verbunden, wodurch dieses erwärmt und dadurch die Bildung von Kondensat reduziert bzw. vermieden wird.These The object is achieved by a device for heating gas-conducting components in through which gas flows System of an insufflator, respiratory or respiratory therapy device, thereby characterized in that it has an electrical connection to one of Respirator or Insufflator independent Energy source has. This device is to be heated with the Connected component, causing this heated and thereby the formation condensate is reduced or avoided.
Da die beschriebenen Probleme überwiegend im Zusammenhang mit aktiven Atemgasbefeuchtern auftreten, kann die Vorrichtung erfindungsgemäß von einem solchen direkt gespeist werden ohne die Notwendigkeit einer separaten Steuer- und Regeleinheit. Dennoch ist eine solche natürlich durchaus ebenfalls möglich, z.B. in Form eines einfachen Steckernetzteils.There the described problems predominantly may occur in the context of active humidifiers Device according to the invention of a be fed directly without the need for a separate Control unit. Nevertheless, such a course is quite also possible, e.g. in the form of a simple plug-in power supply.
Wesentlicher Vorteil einer solchen Vorrichtung ist die Möglichkeit, auf kostengünstige Weise die Betriebsstabilität bereits im Markt befindlicher Beatmungsgeräte zu verbessern, wenn diese in Kombination mit aktiven Atemgasbefeuchtern betrieben werden und es zu den oben beschriebenen Problemen kommt. Ein kostenintensives und aufwendiges Redesign solcher Beatmungsgeräte kann so vermieden werden.essential Advantage of such a device is the possibility in a cost effective manner the operational stability already on the market ventilators, if these operated in combination with active breathing humidifiers and it comes to the problems described above.
