Abstract

Carbon dioxide-absorbing compositions for oxygen-circulating devices based on calcium hydroxide result in elevated carbon dioxide values in the respiratory circulation at the start of the ventilation, especially at low external temperatures. The onset of the reaction of the calcium hydroxide with the carbon dioxide from the respiratory air is accelerated by the presence of the heavy metals copper, zinc, manganese and iron. The metals may be admixed as oxide or salt with the calcium hydroxide. This results in an absorbing composition which absorbs sufficient CO2 right from the start of the ventilation, so that no elevated CO2 concentration occurs in the respiratory circulation.

Description

Kohlendioxid-Absorptionsmassen auf der Basis von Calciumhydroxid werden in Sauerstoff-Kreislaufgeräten verwendet, um das exhalierte Kohlendioxid aus dem Atemkreislauf zu entfernen.Carbon dioxide absorption masses based on Calcium hydroxide are used in oxygen rebreathers used to remove the exhaled carbon dioxide Remove breathing circuit.

Ein solches Sauerstoff-Kreislaufgerät ist z. B. in der DE-PS 12 43 984 beschrieben.Such an oxygen cycle device is such. B. in the DE-PS 12 43 984 described.

Zu Beginn der Beatmung, wenn die Absorptionsmasse noch nicht durch die Reaktionswärme aufgeheizt ist, verläuft die Reaktion zwischen Calciumhydroxid und Kohlendioxid ziemlich träge. Dies kann bei Fluchtgeräten, die bereits sofort nach dem Anlegen sehr stark beatmet werden, zu einem anfänglichen Ansteigen der CO2-Konzentration im Atemkreislauf führen. Erst mit zunehmender Erwärmung der Absorptionsmasse geht die CO2-Konzentration wieder zurück. Dies kann jedoch, vor allem bei niedrigen Außentemperaturen, eine längere Zeit dauern. Erhöhte CO2-Konzentrationen in der Einatemluft bedeuten aber, vor allem unter einer Streßsituation während einer Flucht, eine Erschwernis der Atmung des Gerätträgers. Aus der DE-OS 23 16 214 ist ein Atemkalk bekannt, dem Glykol zugesetzt ist. Dieses Glykol dient in erster Linie dazu, der Austrocknung des Atemkalks entgegenzuwirken. Zusätzlich erhöht der Glykolzusatz die Reaktionsfähigkeit des Atemkalks bei Temperaturen unter 0°C. Bei höheren Temperaturen gibt es keinen Effekt hinsichtlich erhöhter Reaktionsgeschwindigkeit.At the beginning of ventilation, when the absorption mass has not yet been heated up by the heat of reaction, the reaction between calcium hydroxide and carbon dioxide is rather slow. This can lead to an initial increase in the CO 2 concentration in the breathing circuit in escape devices that are very heavily ventilated immediately after being put on. The CO 2 concentration only drops again as the absorption mass heats up. However, this can take a long time, especially when the outside temperature is low. Increased CO 2 concentrations in the inhaled air mean, especially under a stressful situation during an escape, an difficulty in breathing the device wearer. From DE-OS 23 16 214 a soda lime is known, the glycol is added. This glycol primarily serves to counteract the drying out of the soda lime. The addition of glycol increases the reactivity of the soda lime at temperatures below 0 ° C. At higher temperatures there is no effect regarding increased reaction speed.

Die vorliegende Erfindung hat zum Ziel, die Reaktionsfähigkeit des Calciumhydroxids so weit zu steigern, daß auch bei starker Beatmung kurz nach dem Anlegen des Fluchtgerätes sowohl bei niedrigen als auch bei höherer Umgebungstemperatur keine erhöhten CO2-Konzentrationen auftreten.The aim of the present invention is to increase the reactivity of the calcium hydroxide to such an extent that, even in the case of strong ventilation, shortly after the escape device is put on, there are no increased CO 2 concentrations either at low or at a higher ambient temperature.

Dieses Ziel wird dadurch erreicht, daß dem Calciumhydroxid 0,1 bis 10 Gew.-% eines Schwermetallsalzes und/oder eines Schwermetalloxids zugesetzt werden.This goal is achieved in that the Calcium hydroxide 0.1 to 10 wt .-% of one Heavy metal salt and / or a heavy metal oxide be added.

Die Schwermetalle wirken als Katalysator bei der Umsetzung von Calciumhydroxid mit Kohlendioxid und beschleunigen somit die Reaktion. Dies macht sich besonders bemerkbar, solange die Absorptionsmasse noch kalt ist. Sie verlieren ihre Wirksamkeit nicht, wenn die Absorptionsmasse durch Gebrauch erwärmt wird.The heavy metals act as a catalyst in the Implementation of calcium hydroxide with carbon dioxide and thus accelerate the reaction. This is clear particularly noticeable as long as the absorption mass is still there is cold. They don't lose their effectiveness, though the absorption mass is heated by use.

Als Schwermetalle können Kupfer, Zink, Mangan oder Eisen verwendet werden. Neben den Oxiden dieser Metalle sind ihre Chloride und Nitrate anwendbar.Copper, zinc, manganese or Iron can be used. In addition to the oxides of these Metals are their chlorides and nitrates.

Eine besonders gute Wirksamkeit wird erzielt, wenn man das Schwermetallsalz und/oder Schwermetalloxid dem Löschwasser beigibt, so daß es sich während des Löschvorgangs in das Calciumhydroxid einbauen kann.A particularly good effectiveness is achieved when one the heavy metal salt and / or heavy metal oxide Extinguishing water adds, so that it is during the Extinguishing process can build into the calcium hydroxide.

Die Erfindung soll in folgendem Beispiel erläutert werden:The invention is illustrated in the following example will:

20 g Kupferchlorid werden in 2 Litern Wasser gelöst. Zu der Lösung wird unter Rühren 1 kg Calciumoxid gegeben. Nach dem vollständigen Einrühren wird die gebildete viskose Masse noch 1 Stunde lang geknetet. Dann wird die Masse auf einem Pastengranulator zu Teilchen von 4-5 mm Durchmesser granuliert und auf einen Wassergehalt von 16% getrocknet.20 g of copper chloride are dissolved in 2 liters of water. 1 kg of calcium oxide is added to the solution with stirring given. After stirring in completely, the kneaded viscous mass formed for 1 hour. Then the mass is added to a paste granulator Granules of 4-5 mm in diameter and granulated dried a water content of 16%.
