Description

Sauerstoff erzeugendes Atemschutzgerät Oxygen generating breathing apparatus
BesehreibungBesehreibung
Die Erfindung betrifft ein Sauerstoff erzeugendes Atemschutzgerät , das eine an einen Atemschlauch und einen A- tembeutel angeschlossene, zur Erzeugung von Sauerstoff in beiden Richtungen durchströmte Chemikalpatrone umfasst .The invention relates to an oxygen-generating respirator comprising a connected to a breathing tube and an A- tembeutel, for generating oxygen in both directions flowed through chemical cartridge.
Bei Atemschutzgeräten dieser Art wird die ausgeatmete Luft des Benutzers über eine in einem Kanister oder einer Patrone (im folgenden als Chemikalpatrone bezeichnet) befindliche Chemikalie, zum Beispiel in körniger Form vor- liegendes Kaliumhyperoxid (KO2) , geleitet . Durch das in der Ausatemluft enthaltene und mit der Chemikalie reagierende Kohlendioxid wird in einer exothermen Reaktion Sauerstoff erzeugt, der aus der Chemikalpatrone in einen A- tembeutel gelangt und vom Benutzer wieder eingeatmet wird. Diese Geräte, bei denen das Ein- und Ausatmen in einer sogenannten Pendelatmung über die Chemikalie und gegen den dadurch bedingten Widerstand erfolgt, sind im Falle einer plötzlichen Kontamination der Luft als Selbstretter oder Fluchthilfegeräte für eine begrenzte Einsatzzeit von beispielsweise 20 Minuten und den einmaligen Gebrauch, beispielsweise in Bergwerken, bestimmt . Das aus der Chemikalpatrone mit Atembeutel und Atemschlauch bestehende Rettungsgerät hat eine kleine Bauform und wird, verpackt in einen stabilen Behälter, vom Benut- zer während der Tätigkeit in einem gefährdeten Arbeitsbereich, beispielsweise durch Befestigung am Gürtel , aus Sicherheitsgründen ständig mitgeführt (passive Verwendung) , um im Ernstfall sofort angelegt und aktiv benutzt werden zu können . Trotz der hohen und über zumeist viele Jahre des nicht notwendigen aktiven Einsatzes lang andauernden mechanischen Belastung, beispielsweise im rauen Bergwerksbetrieb, muss das Gerät dennoch ständig einsatzbereit und bei einem Notfall voll funktionsfähig sein . Dem steht j edoch entgegen, dass die für den leichten A- temluftdurchgang in körniger Form vorliegende Chemikalie aufgrund der vielfachen, gegebenenfalls langjährigen Erschütterung des Gerätes einer allmählichen Pulverisierung unterliegt . Das Pulver kann in den Atembeutel fallen oder sich im Bereich des Bodens der Chemikalpatrone und damit im Bereich der Öffnung zum Atembeutel auf einem die fei- nen Staubpartikel zurückhaltenden watteartigen Material absetzen und aufgrund von Feuchte oder der aufgrund der exothermen Reaktion zu Sauerstoff erzeugten Wärme zu Verklebungen mit der Watte bzw. Verbackungen führen, so dass ungehinderte Durchströmung der Atemluft und damit die Funktionsfähigkeit des Rettungsgerätes nicht gewährleistet ist .In respirators of this type, the exhaled air of the user is passed through a chemical present in a canister or cartridge (hereinafter referred to as a chemical cartridge), for example, in granular form, potassium peroxide (KO 2 ). The carbon dioxide contained in the exhaled air and reacting with the chemical produces oxygen in an exothermic reaction, which is transferred from the chemical cartridge into an aftertag and is inhaled again by the user. These devices, in which the inhalation and exhalation takes place in a so-called pendulum breathing on the chemical and the resulting resistance are in the event of sudden contamination of the air as self-rescuers or escape aids for a limited period of use, for example, 20 minutes and a single use, in mines, for example. The rescue device consisting of the chemical cartridge with breathing bag and breathing tube has a small design and, when packed in a sturdy container, is constantly carried by the user during work in a hazardous working area, for example by being fastened to the belt for safety reasons (passive use). In case of emergency, you can immediately create and actively use it. Despite the high and over many years of unnecessary active use long-lasting mechanical stress, for example, in the rough Mine operation, the device must still be ready for use and fully functional in an emergency. However, this is counteracted by the fact that the chemical present in granular form for the passage of light air is subject to gradual pulverization due to the repeated, possibly long-lasting vibration of the device. The powder can fall into the breathing bag or settle in the region of the bottom of the chemical cartridge and thus in the region of the opening to the breathing bag on a cotton-like material which retains the fine dust particles and become adhesions due to moisture or the heat generated as a result of the exothermic reaction to oxygen with the cotton or Verbackungen lead, so that unimpeded flow through the air and thus the functioning of the rescue device is not guaranteed.
Einer Härtung des Granulats , die den Abrieb und die Staubbildung verringern würde, steht eine verminderte Re- aktionsfähigkeit und eine verzögerte Reaktion der Chemikalie mit dem Kohlendioxid entgegen, so dass in diesem Fall zu wenig Sauerstoff erzeugt wird.Hardening of the granules, which would reduce abrasion and dust formation, is counteracted by reduced reactivity and a delayed reaction of the chemical with the carbon dioxide, so that in this case too little oxygen is produced.
Um eine gleichmäßige Durchströmung der in dem Kanister untergebrachten Chemikalie zu erreichen, ist es aus derIn order to achieve a uniform flow through the chemical accommodated in the canister, it is known from US Pat
DE 34 26 757 bereits bekannt, in dem Kanister ein siebartiges , als Dom geformtes , auf der Seite der Chemikalie mit Watte belegtes Luftdurchgangselement auszubilden, mit dem eine möglichst große Luftdurchgangsfläche zwischen der Chemikalie und dem Atembeutel geschaffen wird und die Staubablagerung pro Flächeneinheit minimiert wird. Ein vor der Öffnung zum Atembeutel angeordnetes , spitzwinklig geformtes Sieb soll das infolge der exothermen Reaktion der Chemikalie mit dem Kohlendioxid schmelzende Granulat seitlich in einen Auffangring ableiten und dadurch den ständigen freien Luftdurchgang zwischen dem Kanister (Chemikalpatrone) und dem Atembeutel gewährleisten . Die Pulverisierung des Granulats infolge langjähriger mechanischer Belastung bei der passiven Nutzung und eine dadurch bedingte Funktionsuntüchtigkeit des Rettungsgerätes kann dadurch mit Sicherheit nicht ausgeschlossen werden .DE 34 26 757 already known in the canister a sieve-like, formed as a dome, on the side of the chemical with cotton coated air passage element, with the largest possible air passage area between the chemical and the breathing bag is created and the dust deposition per unit area is minimized. A arranged in front of the opening to the breathing bag, acute-angled shaped screen to derive the result of the exothermic reaction of the chemical with the carbon dioxide melting granules laterally into a collecting ring and thereby the constant free passage of air between the canister (Chemical cartridge) and the breathing bag. The pulverization of the granules as a result of many years of mechanical stress in passive use and the resulting inoperability of the rescue device can not be ruled out with certainty.
Des weiteren wurde bereits vorgeschlagen, in die Chemikalpatrone ein sich über deren gesamte Länge in Durch- • Strömrichtung erstreckendes , mehrfach gefaltetes Drahtge- webe aus Edelstahl einzulegen und zusätzlich auch an den Stirnseiten ein elastisches Drahtgewebe anzuordnen und dadurch die auf das Granulat wirkenden Erschütterungen zu vermindern . Vermeiden lassen sich die Erschütterungen dadurch j edoch nicht vollständig, da die gefaltete Gewebe- einlage in sich nicht formstabil ist und sich in der Chemikalpatrone verschieben kann . Die gleichmäßige Befüllung der Patrone mit dem Granulat ist schwierig oder nicht möglich . Die atemphysiologische Leistungsfähigkeit ist ohnehin und erst recht nach einer vorangegangenen mecha- nischen Belastung deutlich eingeschränkt . Mit dem mehrschichtig übereinander gelegten Drahtgeflecht , das sich auch flächig an die Innenwände der Patrone anlegen kann, wird ein das Granulat vollständig durchziehender Luftdurchgangskanal geschaffen, so dass ein großer Teil des in der Ausatemluft enthaltenen Kohlendioxids nicht mit der Chemikalie in Berührung kommt und somit nicht absorbiert wird.Furthermore, it has been proposed, one over its entire length in transit • flow direction extending into the chemical cartridge, insert multiple-bent wire mesh of stainless steel and additionally arrange also on the front sides an elastic wire mesh, thereby reducing the forces acting on the granular shock , However, the shocks can not be completely avoided as the folded fabric insert is not dimensionally stable in itself and can shift in the chemical cartridge. The uniform filling of the cartridge with the granules is difficult or impossible. The respiratory physiological performance is already clearly limited and certainly after a previous mechanical load. With the multi-layer superimposed wire mesh, which can also create a flat against the inner walls of the cartridge, the granules completely traversing air passageway is created so that a large part of the carbon dioxide contained in the exhaled air does not come into contact with the chemical and thus not absorbed becomes.
Der Erfindung liegt die Aufgabe zugrunde, ein Atemschutz- gerät zur Sauerstofferzeugung anzugeben, das als Selbstretter für unter robusten Bedingungen tätige Personen auch nach langer, über Jahre andauernder äußerer mechanischer Einwirkung in einem notwendigen Einsatzfall sofort und mit hoher atemphysiologischer Leistung uneinge- schränkt funktionsfähig ist . Erfindungsgemäß wird die Aufgabe mit einem Atemschutzgerät gelöst, dessen mit einer Sauerstoff erzeugenden Che- mikalie gefüllte, luftdurchströmte Chemikalpatrone gemäß den Merkmalen des Patentanspruchs 1 ausgebildet ist .The invention has for its object to provide a respirator for oxygen production, which is as self-rescuer for people working under robust conditions, even after long lasting over years external mechanical impact in a necessary application immediately and with high respiratory physiological performance is fully functional. According to the invention the object is achieved with a respiratory protective device, the filled with an oxygen-generating chemical chemical, perfused chemical cartridge according to the features of claim 1 is formed.
Vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche .Advantageous developments and expedient embodiments of the invention are the subject of the dependent claims.
Das Sauerstoff erzeugende Atemschutzgerät umfasst eine Chemikalpatrone, in der mit dem in der Ausatemluft enthaltenen Kohlendioxid Sauerstoff für die Atmung erzeugt wird. An die Chemikalpatrone ist an einer Seite ein Atemschlauch mit Mundstück und an der gegenüberliegenden Seite ein Atembeutel als Luftreservoir angeschlossen . Die Chemikalpatrone ist gemäß der Erfindung mit Hilfe von fest angeordneten Haltegittern in einzelne, aufeinander folgende Luftbehandlungskamnaern unterteilt . In den beiden äußeren Luftbehandlungskammern ist - angrenzend an die jeweilige stirnseitige Abdeckung der Chemikalpatrone - ein Stoßdämpfungsmittel aus einem mehrlagigen und mithin elastischen Feindrahtgestrick angeordnet , während in den mittleren Luftbehandlungskammern ein ebenfalls aus einem mehrlagigen Feindrahtgestrick bestehendes , aber Zickzack- förmig gefaltetes und senkrecht auf den Haltegittern ste- hendes , d.h . in Strömungsrichtung ausgerichtetes Dämpfungselement, das an einer der zickzackförmig verlaufenden Kanten fixiert ist, untergebracht ist . Die in benachbarten Luftbehandlungskammern vorgesehenen zickzackförmi- gen Dämpfungselemente sind j edoch nicht in einer Flucht, sondern zueinander versetzt , vorzugsweise spiegelbildlich, angeordnet . In den Luftbehandlungskammern sind die im Wesentlichen in körniger Form vorliegenden Chemikalien zur Sauerstofferzeugung und - wahlweise in einer Kammer zur Kohlendioxidbindung - durch Rütteln und Pressen eng gepackt untergebracht . Die elastischen Feindrahtgestricke der Stoßdämpfungsmittel haben eine sehr glatte Außenfläche .The oxygen-generating respirator comprises a chemical cartridge in which oxygen is generated for breathing with the carbon dioxide contained in the exhaled air. To the chemical cartridge on one side a breathing tube with mouthpiece and on the opposite side a breathing bag is connected as an air reservoir. The chemical cartridge is subdivided according to the invention by means of fixed holding lattices into individual, successive Luftbehandlungskamnaern. In the two outer air treatment chambers - adjacent to the respective end cover of the chemical cartridge - a shock absorbing means of a multi-layer and thus elastic fine wire knitted arranged while in the middle air treatment chambers also consisting of a multi-layer fine wire knit, but zigzag folded and perpendicular to the holding lattices standing, ie. aligned in the flow direction damping element, which is fixed to one of the zigzag running edges, is housed. However, the zigzag-shaped damping elements provided in adjacent air-treatment chambers are not aligned, but are offset relative to one another, preferably in mirror image form. In the air treatment chambers, the present in granular form of chemicals for oxygen generation and - optionally housed in a chamber for carbon dioxide - packed tightly by shaking and pressing. The elastic fine wire knitwear The shock absorber has a very smooth outer surface.

Das Chemikalgranulat ist derart elastisch abgefedert in der Patrone untergebracht , dass trotz langandauernder hoher mechanischer Belastung kaum Abrieb, das heißt, keine der Funktionsfähigkeit entgegenstehende Pulverisierung des Granulats erfolgt . Zudem erlaubt die erfindungsgemäße Ausbildung der Chemikalpatrone die Verwendung eines sehr grobkörnigen - kostengünstigen - Chemikals und eine optimale Durchströmung der Chemikalpatrone mit hohen Leis- tungsdaten .With the oxygen-generating respirator according to the present invention, even after many years of non-active use, in which the device and in particular the chemical, high mechanical loads (shocks, shocks) has been exposed, in the case of active use immediately and without restriction higher power possible to provide the oxygen required for the respiration of the user. The chemical granules are housed so resiliently cushioned in the cartridge, that despite long-lasting high mechanical stress hardly abrasion, that is, no functioning of the counteracting pulverization of the granules. In addition, the inventive design of the chemical cartridge allows the use of a very coarse-grained - inexpensive - chemical and optimal flow through the chemical cartridge with high performance data.
In Ausgestaltung der Erfindung sind vorzugsweise vier Luftbehandlungskammern vorgesehen . Dabei sind die beiden äußeren Kammern deutlich kleiner als die inneren . Die an den Atembeutel angeschlossene äußere Kammer ist mit Lithiumhydroxid-Tabletten als Kohlendioxid bindendes Chemikal gefüllt, während die anderen Kammern ein sehr grobkörniges Kaliumhyperoxid-Granulat zur Sauerstofferzeugung enthalten . Durch die an den Atemschlauch anschließende kleine (erste) Luftbehandlungskammer ist auch im Minustemperaturbereich sofort eine Sauerstofferzeugung gewährleistet .In an embodiment of the invention preferably four air treatment chambers are provided. The two outer chambers are significantly smaller than the inner ones. The outer chamber connected to the breathing bag is filled with lithium hydroxide tablets as a carbon dioxide-binding chemical, while the other chambers contain a very coarse-grained potassium hydroxide granules for oxygen production. By connecting to the breathing tube small (first) air treatment chamber, an oxygen production is guaranteed even in the minus temperature range immediately.
Gemäß einem weiteren wichtigen Merkmal der Erfindung be- stehen die in den beiden äußeren Kammern vorgesehenen Dämpfungsmittel aus Kupfer und dienen gleichzeitig als zusätzliche Wärmetauscher zur Abkühlung der durch die e- xotherme Reaktion bei der Sauerstofferzeugung stark erwärmten Atemluft , so dass der Atemkomfort verbessert wird. .According to another important feature of the invention, the damping means provided in the two outer chambers consist of copper and simultaneously serve as additional heat exchangers for cooling the respiratory air, which is strongly heated by the e-xothermal reaction during the oxygen generation, so that the breathing comfort is improved. ,

In the first (upper) air treatment chamber 15 and in the fourth (lower)
Luftbehandlungskammer 18 befinden sich - j eweils von der oberen und unteren Abdeckung 10 , 9 ausgehend - ein Grobsieb 19a, 19b aus Edelstahl , ein Feinsieb 20a, 20b aus Kupfer und ein mehrlagiges , ebenes elastisches Feindraht- gestrick aus Kupfer als obere und untere Stoßdämpfungsmittel 21a, 21b . Zu der j eweils anschließenden zweiten bzw . dritten Luftbehandlungskanαmer 16 , 17 hin werden die erste und vierte Luftbehandlungskairaner 15 und 18 jeweils durch das oben erwähnte Haltesieb 14a und 14c begrenzt . In dem verbleibenden Zwischenraum befindet sich in der ersten (oberen) Luftbehandlungskammer 15 grobkörniges Kaliumhyperoxid-Granulat (KO2) 22 und in der vierten (unteren) Luftbehandlungskammer 18 sind Lithiumhydroxid- Tabletten (LiOH) 23 , dass heißt , das KO2 und das LiOH sind zu der starren oberen und unteren Abdeckung 9 , 10 hin elastisch gelagert , um Erschütterungen und Stöße abzufangen und eine Pulverisierung zu vermeiden . Die Feinsiebe 20a, 20b sind zur Sicherheit da und halten gegebenenfalls doch vorhandene feine Kθ2-Partikel in der Chemi- kalpatrone 2 zurück .Air treatment chamber 18 are - in each case from the upper and lower cover 10, 9 starting - a coarse sieve 19a, 19b made of stainless steel, a fine wire 20a, 20b made of copper and a multi-layered, flat elastic fine wire knit of copper as upper and lower shock absorbing means 21a , 21b. To each of the subsequent second respectively . Third Luftbehandlungskanαmer 16, 17 toward the first and fourth Luftbehandlungskairaner 15 and 18 respectively bounded by the above-mentioned holding screen 14 a and 14 c. In the remaining space in the first (upper) air treatment chamber 15 are coarse potassium peroxide granules (KO 2 ) 22 and in the fourth (lower) air treatment chamber 18 are lithium hydroxide tablets (LiOH) 23, that is, the KO 2 and the LiOH are elastically mounted to the rigid upper and lower cover 9, 10 to absorb shock and shock and to avoid pulverization. The fine sieves 20a, 20b are there for safety and possibly retain any fine Kθ 2 particles present in the chemical cartridge 2.
Die Anordnung der ersten, relativ flachen Luftbehandlungskammer 15 gewährleistet die sofortige Funktion des Atemschutzgerätes , das heißt, die Reaktion des Kohlendioxids mit dem Kaliumhyperoxid zu Sauerstoff, bereits bei sehr niedrigen Temperaturen, zum Beispiel -5°C . Das Lithiumhydroxid in der vierten Luftbehandlungskammer 18 hat die Aufgabe, den Cθ2-Überschuss zu binden, der bei hohen Atemfrequenzen entsteht . Eine wichtige Funktion der aus Kupfer bestehenden Stoßdämpfungsmittel 21a, 21b besteht neben dem Dämpfungseffekt in der Wirkung als zusätzlicher Wärmetauscher, so dass die aufgrund der exothermen Reaktion vergleichsweise hohe Einatemtemperatur deutlich gesenkt werden kann .The arrangement of the first, relatively shallow air treatment chamber 15 ensures the immediate function of the respirator, that is, the reaction of the carbon dioxide with the potassium peroxide to oxygen, even at very low temperatures, for example -5 ° C. The lithium hydroxide in the fourth air treatment chamber 18 has the task of binding the excess CO 2 , which arises at high respiratory rates. An important function of the existing copper shock absorbing means 21a, 21b in addition to the damping effect in the effect of an additional heat exchanger, so that the relatively high inhalation temperature due to the exothermic reaction can be significantly reduced.
In der zweiten und dritten Luftbehandlungskairaner 16 und 17 befindet sich j eweils ein aus einem Feindrahtgestrick bestehendes , flächiges , aber zickzackförmig gefaltetes Dampfungselernent 24 , 25. Die in Strömungsrichtung hochkant in den Luftbehandlungskammern 16 , 17 angeordneten Dämpfungselemente 24 , 25 sind an j eweils einer - zickzackförmig verlaufenden Kante an einem Drahtgitter 26 , 27 befestigt . Die Längskanten 28 der Falten, das heißt die Faltenkanten der Dämpfungselemente 24 , 25 verlaufen im Abstand parallel zu den Seitenwänden 29 der Chemikalpat- rone 2. Das Feindrahtgestrick der Dämpfungselemente 24 , 25 besteht aus vier - aus einem zusammengelegten und in Längsrichtung einmal gefalteten Schlauch gebildeten - Schichten aus Edelstahl und einem zwischen den beiden so gebildeten Außenschichten liegenden, stabilisierend wirkenden Kupferdrahtgestrick . Diese fünf Schichten sind zu- dem zusammengeheftet, so dass in Verbindung mit der Befestigung an dem Drahtgitter 26 bzw. 27 kompakte Dämpfungselemente 24 , 25 vorhanden sind, deren Wände (Falten) in sich und als Ganzes elastisch sind . Die von den elastischen Wänden des j eweiligen Dämpfungselements 24 , 25 begrenzten Zwischenräume sind durch Ausüben eines Pressdruckes und Rütteln vollständig mit dem Kaliumhyperoxid- Granulat 22 gefüllt . Aufgrund der elastischen Fixierung des Granulats in mehreren mittels der Haltesiebe 14 voneinander getrennten Luftbehandlungskammern 15 bis 18 so- wie mit den oberen und unteren Stoßdämpfungsmitteln 21a, 21b und den beiden zickzackförmigen Dämpfungselementen 24 , 25 sind die in der Chemikalpatrone 2 untergebrachten Chemikalien 22 , 23 mit Bezug auf von außen einwirkende Erschütterungen und Stöße derart elastisch fixiert, das der Abrieb und die Staubbildung vernachlässigbar klein sind und das Atemschutzgerät auch nach vielen Jahren der passiven Benutzung bei einem aktiven Einsatz in einem Ernstfall sofort funktionsfähig ist .In the second and third Luftbehandlungskairaner 16 and 17 is in each case one consisting of a fine wire knit, flat, but zigzag folded Dampfungselernent 24, 25. The upright in the flow direction in the air treatment chambers 16, 17 arranged damping elements 24, 25 are in each case a - zigzagged edge on a wire mesh 26, 27 attached. The longitudinal edges 28 of the folds, that is to say the fold edges of the damping elements 24, 25 extend at a distance parallel to the side walls 29 of the chemical cartridge 2. The fine wire knit of the damping elements 24, 25 consists of four - formed from a folded and longitudinally folded tube - Layers of stainless steel and a lying between the two outer layers thus formed, stabilizing acting Kupferdrahtgestrick. These five layers are also stapled together, so that in connection with the attachment to the wire mesh 26 and 27 compact damping elements 24, 25 are present, the walls (folds) are elastic in itself and as a whole. The spaces bounded by the elastic walls of the respective damping element 24, 25 are completely filled with the potassium hypoxyd granules 22 by exerting a pressing pressure and shaking. Due to the elastic fixation of the granules in several by means of holding sieves 14 separate air treatment chambers 15 to 18 and with the upper and lower shock absorbing means 21a, 21b and the two zigzag damping elements 24, 25 are housed in the chemical cartridge 2 chemicals 22, 23 with With respect to externally applied shocks and shocks elastically fixed so that the abrasion and dust are negligible and the respirator is immediately functional even after many years of passive use in an active use in an emergency.
In Anbetracht der Kammerbildung und der Anordnung von zwei zickzackförmigen Dämpfungselementen 24 , 25 werden Letztere in Bezug auf die Zickzackform spiegelbildlich zueinander angeordnet , so dass deren beiderseitige Wände versetzt zueinander verlaufen, das heißt nicht in einer Flucht liegen. Dadurch wird eine besonders gleichmäßige Durchströmung der beiden mit Kaliumhyperoxid-Granulat 22 gefüllten Luftbehandlungskammern 16 , 17 erreicht , so dass ein kostengünstiges grobkörniges Granulat verwendet werden kann und aufgrund der dadurch bedingten optimalen Durchströmung mit Atemluft letztlich sehr gute atemphysiologische Leistungsdaten erzielt werden . In view of the chamber formation and the arrangement of two zigzag damping elements 24, 25, the latter are arranged in mirror image relative to one another with respect to the zigzag shape, so that their mutual walls are offset from one another, that is, they are not in alignment. As a result, a particularly uniform flow of the two with potassium peroxide granules 22nd filled air treatment chambers 16, 17 is reached, so that a cost-effective coarse-grained granules can be used and due to the resulting optimal flow of respiratory air ultimately very good respiratory physiological performance data can be achieved.
