flüssigen Narkosemittelnliquid anesthetics
Es ist ein Verdampfer für Narkosegeräte mit bei normaler Temperatur flüssigen Narkosemitteln vorgeschlagen worden, bei dem in die Zuleitung zum Verdampfer hinter der Abzweigung zum By-Pass ein derart langes Rohrstück eingeschaltet ist, daß das infolge der Druckschwankungen im Verdampferraum aus diesem in die Zuleitung zurücktretende Gas nicht bis zum By-Pass-Ventil gelangen kann. Dabei kann das Rohrstück wendelförmig ausgebildet sein. Dadurch soll ein Veränderung in der Zusammensetzung der Narkosegasgemische verhindert werden.A vaporizer has been proposed for anesthesia machines with anesthetics that are liquid at normal temperature, in which such a long piece of pipe is switched on in the supply line to the evaporator behind the junction to the by-pass is that as a result of the pressure fluctuations in the evaporator chamber from this back into the supply line not up to By-pass valve can arrive. The pipe section can be designed helically. This is supposed to be a change can be prevented in the composition of the anesthetic gas mixtures.
Die Neuerung erstrebt eine andere Lösung der gleichen Aufgabe. Die Neuerung besteht darin, daß das Leitungsstück statt an die Zuleitung zum Verdampfer in die Verbindung zwischen diesem und dem Mischgefäß und&as Steuerventil in die Zuleitung vor dem Verdampfer eingeschaltet ist. Die Erfindung hat den Vorteil, daß eine Veränderung der Zusätze des Narkosegases verhindert wird.The innovation aims at a different solution to the same task. The innovation is that the line piece takes place to the supply line to the evaporator in the connection between this and the mixing vessel and & as control valve in the supply line before the vaporizer is switched on. The invention has the advantage that a change in the additives of the anesthetic gas is prevented.
Weitere Einzelheiten der Neuerung seien an Hand des in der Zeichnung dargestellten Ausführungsbeispiels erläutert. Durch die Zuleitung ;5 strömt ein Gas wie Luft, Luftgemische mit oder ohne Zusatz von Zyklopropan, Lachgas, od. dgl. über das Einstellventil 6 und den Strömungsmesser 6a dem Verdampfer 4 zu, der mit Hälothan gefüllt sein kann. In dessen Abgangsleitung 5 ist ein verhältnismäßig langes Rohrstück 12 eingeschaltet, das in der Mischkammer 8 endet.Further details of the innovation are explained using the exemplary embodiment shown in the drawing. A gas such as air, air mixtures with or without the addition of cyclopropane, laughing gas or the like flows through the supply line 5 the adjustment valve 6 and the flow meter 6a to the evaporator 4, which can be filled with halothane. In its outlet line 5, a relatively long pipe section 12 is switched on, which ends in the mixing chamber 8.
In diese mündet die von dem Einstellventil 10 und dem Strömungsmesser 10a kommende Leitung 1, durch die der Mischkammer ebenfalls ein Gas, wie Luft, Luftgemische oder Nährgasgemische der obenbeschriebenen Art zugeführt werden. Von der Mischkammer führt die Leitung 11 zum Patienten.The flow control valve 10 and the flow meter open into this 10a incoming line 1, through which the mixing chamber also a gas, such as air, air mixtures or nutrient gas mixtures of the of the type described above. The line 11 leads from the mixing chamber to the patient.
Die Länge des Rohrstückes 12 ist nach folgenden Überlegungen bestimmt. Bei Anwendung des Gerätes treten im VerdampferraumThe length of the pipe section 12 is based on the following considerations definitely. When using the device occur in the evaporator room
im gleichen Maße Druckschwankungen auf, wie sie in der Mischkammer 8 und eier Leitung 11 sich durch die Beatmung des Patienten ergeben. Die Druckschwankungen im Verdampferraum 15 können dazu führen, daß bei einer kurzen Verbindung der Mischkammer 8 und der Verdampfericammer 15 unkontrollierbare Gasmengen in den Verdampferraum zurückströmen, sieh dort mit dem Narkosemittel sättigen und daraufhin wiederum in die zum Patienten führende Leitung in unkontrollierbarer Menge gelangen. Derart könnte sich der Gehalt in dem zum Patienten geführten Gasgemisch an verdampften Narkosemittel unerwünscht verändern. Die Länge des Rohrstückes 12 wird nun so bemessen, daß bei den möglichen maximal auftretenden Druckunterschieden Gas aus der Mischkammer 8 nicht wieder in den Verdampferraum 15 eintreten kann.pressure fluctuations to the same extent as in the Mixing chamber 8 and a line 11 result from the ventilation of the patient. The pressure fluctuations in the evaporator chamber 15 can lead to a short connection the mixing chamber 8 and the evaporator chamber 15 uncontrollable Gas quantities flow back into the vaporizer room, see saturate there with the anesthetic and then again get into the line leading to the patient in an uncontrollable amount. Such could be the salary in the for Unwanted changes in the gas mixture of vaporized anesthetic agent carried by the patient. The length of the pipe section 12 is now dimensioned so that with the possible maximum pressure differences that occur, gas from the mixing chamber 8 does not return can enter the evaporator chamber 15.
Das Rohrstück 12 kann wendelförmig oder auch in Form eines Behälters mit die Weglänge des Gases ausdehenden Einbauten gebildet sein.The pipe section 12 can be helical or in the form of a Can be formed with the path length of the gas expanding internals.
