Definitions
- the invention relates to a protective cover made of gas-tight material.
- An emergency package for protecting a person in an atmosphere contaminated with pollutants is known from European patent specification 0211914.
- the outside air is led into the interior of the emergency package via a supply air filter.
- a filter that prevents all poisonous gases that occur during a fire.
- no filter is a protection against insufficient oxygen content, which can also arise in the event of a fire in the breathing air.
- the object on which the present invention is based is to propose a protective cover made of gas-tight material, the interior of which enables breathing even in the case of various pollutants polluting the environment.
- the protective cover has a connection via which the interior can be connected to a breathing apparatus.
- connection of the protective cover can be connected to the pressure reducer of the breathing apparatus via the medium pressure line.
- the protective cover is designed as a baby carrier.
- the interior of the protective cover according to the invention is independent of the ambient air.
- Respiratory protective devices are an integral part of every fire department ambulance.
- the protective cover itself is made of a fire and smoke resistant material. If it is connected to the known and existing breathing apparatus, the breathing air from the firefighter's "air bottle” gets into the interior of the protective cover. It is thus avoided that any pollutants present in the circulating air get into the interior of the protective cover.
- filters that prevent all poisonous gases that occur in a fire.
- all known protective covers work with a filter.
- the protective cover When designing the protective cover as a baby carrier, it is easy for the firefighter to put the baby to be rescued in the carrier in the event of a fire. Is now the interior connected to the pressure reducer of the firefighter's breathing apparatus via the medium pressure line, the breathing air for the baby in the closed baby carrier comes from the firefighter's air bottle. In the event of a fire, the fireman carries the closed baby rescue bag and thus goes outside with the protected baby.
- a filter is provided which, as described, can only ensure protection against certain pollutants.
- the air is low in oxygen, it is not sufficient if a filter is installed to prevent the baby from suffocation.
- Figure 1 shows the perspective view of a protective cover according to the invention, which is designed as a baby carrier.
- the protective cover 1 can be closed with the zipper 2.
- the baby located in the interior 3 of the protective cover 1 is connected to the outside air via the Connection 4 connected.
- This connection 4 has a rolling thread and is provided with a throttle nozzle 5 which leads to the medium pressure line 6.
- the medium pressure line 6 is connected via a Y-piece 7 to the line which is intended for the firefighter.
- This Y-piece 7 connects the medium pressure line 6 with the pressure reducer of a breathing apparatus, so that this breathing apparatus can supply both the firefighter and the interior 3 of the protective cover 1 with the necessary breathing air via the Y-piece 7.
- the baby to be protected is thus located in the interior 3 of the protective cover 1, it can be saved in a simple manner regardless of the ambient air.
- the firefighter has connected his breathing apparatus to the medium-pressure line 6 of the protective cover 1 via the Y-piece 7 and can thus carry the baby located in the protective cover 1 on the carrying handles 8 and bring them to the outside in a simple manner. Regardless of the type of pollutants in the ambient air and the oxygen content, the baby in the protective cover 1 can thus be saved.
- the invention should not be limited to the baby carrier described, since it is also conceivable that, for example, a tent-like protective cover is used, for example to briefly provide several people in the interior of such a protective cover with breathing air. Furthermore, the protective cover 1 is provided with pressure relief valves 9 which serve to discharge the excess pressure in the closed protective cover.
Abstract
Description
Die Erfindung betrifft eine Schutzhülle aus gasdichtem Material.The invention relates to a protective cover made of gas-tight material.
Aus der europäischen Patentschrift 0211914 ist ein Notpaket zum Schutze einer Person in einer mit Schadstoffen belasteten Atmosphäre bekannt. Bei allen in dieser Patentschrift beschriebenen Ausführungsformen wird die Außenluft über einen Zuluftfilter in das Innere des Notpakets geführt. Es gibt jedoch keinen Filter, der alle bei einem Brand auftretenden Giftgase abhält. Ferner ist kein Filter ein Schutz gegen zu geringen Sauerstoffgehalt, der ebenfalls bei einem Brand in der Atemluft entstehen kann.An emergency package for protecting a person in an atmosphere contaminated with pollutants is known from European patent specification 0211914. In all the embodiments described in this patent, the outside air is led into the interior of the emergency package via a supply air filter. However, there is no filter that prevents all poisonous gases that occur during a fire. Furthermore, no filter is a protection against insufficient oxygen content, which can also arise in the event of a fire in the breathing air.
Die der vorliegenden Erfindung zugrundeliegende Aufgabe besteht darin, eine Schutzhülle aus gasdichtem Material vorzuschlagen, deren Innenraum auch bei verschiedenen, die Umgebung belastenden Schadstoffe ein Atmen ermöglicht.The object on which the present invention is based is to propose a protective cover made of gas-tight material, the interior of which enables breathing even in the case of various pollutants polluting the environment.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schutzhülle einen Anschluß aufweist, über den der Innenraum mit einem Atemschutzgerät verbindbar ist.This object is achieved in that the protective cover has a connection via which the interior can be connected to a breathing apparatus.
Insbesondere ist der Anschluß der Schutzhülle über die Mitteldruckleitung mit dem Druckminderer des Atemschutzgerätes verbindbar.In particular, the connection of the protective cover can be connected to the pressure reducer of the breathing apparatus via the medium pressure line.
Gemäß einer besonders bevorzugten Ausführungsform ist die Schutzhülle als Babytragetasche ausgebildet.According to a particularly preferred embodiment, the protective cover is designed as a baby carrier.
Weitere besonders bevorzugte Ausführungsformen sind in den Unteransprüchen beschrieben.Further particularly preferred embodiments are described in the subclaims.
Der Innenraum der erfindungsgemäßen Schutzhülle ist umluftunabhängig. Atemschutzgeräte sind in jedem Rettungswagen der Feuerwehr fester Bestandteil. Die Schutzhülle selbst besteht aus einem feuer- und rauchabweisenden Material. Wird sie an das an sich bekannte und vorhandene Atemschutzgerät angeschlossen, so gelangt die Atemluft aus der "Luftflasche" des Feuerwehrmannes in den Innenraum der Schutzhülle. Es wird somit vermieden, daß jegliche in der Umluft vorhandenen Schadstoffe in den Innenraum der Schutzhülle gelangen. Wie bereits ausgeführt, gibt es zur Zeit noch keine Filter, die alle bei einem Brand auftretenden Giftgase abhalten. Alle bekannten Schutzhüllen arbeiten jedoch mit einem Filter.The interior of the protective cover according to the invention is independent of the ambient air. Respiratory protective devices are an integral part of every fire department ambulance. The protective cover itself is made of a fire and smoke resistant material. If it is connected to the known and existing breathing apparatus, the breathing air from the firefighter's "air bottle" gets into the interior of the protective cover. It is thus avoided that any pollutants present in the circulating air get into the interior of the protective cover. As already mentioned, there are currently no filters that prevent all poisonous gases that occur in a fire. However, all known protective covers work with a filter.
Bei der Ausgestaltung der Schutzhülle als Babytragetasche ist es auf einfache Weise für den Feuerwehrmann möglich, bei einem Brand das zu rettende Baby in die Tragetasche zu legen. Ist nunmehr der Innenraum der Babytragetasche über die Mitteldruckleitung mit dem Druckminderer des Atemschutzgerätes des Feuerwehrmannes verbunden, so stammt die Atemluft für das in der geschlossenen Babytragetasche befindliche Baby aus der Luftflasche des Feuerwehrmannes. Im Brandfalle trägt der Feuerwehrmann die verschlossene Babyrettungstasche und gelangt somit zusammen mit dem geschützten Baby ins Freie.When designing the protective cover as a baby carrier, it is easy for the firefighter to put the baby to be rescued in the carrier in the event of a fire. Is now the interior connected to the pressure reducer of the firefighter's breathing apparatus via the medium pressure line, the breathing air for the baby in the closed baby carrier comes from the firefighter's air bottle. In the event of a fire, the fireman carries the closed baby rescue bag and thus goes outside with the protected baby.
Bei den bekannten vorhandenen Babytragetaschen ist ein Filter vorgesehen, der wie beschrieben lediglich einen Schutz gegen bestimmte Schadstoffe gewährleisten kann. Ergänzend ist darauf hinzuweisen, daß bei einer sauerstoffarmen Umluft es nicht ausreicht, wenn ein Filter eingebaut ist, um das Baby vor dem Ersticken zu bewahren.In the known baby carrier bags, a filter is provided which, as described, can only ensure protection against certain pollutants. In addition, it should be pointed out that if the air is low in oxygen, it is not sufficient if a filter is installed to prevent the baby from suffocation.
Es besteht auch nicht die Möglichkeit, aufgrund der Dringlichkeit des Rettungsvorganges eine Analyse der Umluft zu machen und dann zu entscheiden, welcher Filter für bestimmte Stoffe gewählt werden sollte.It is also not possible to make an analysis of the circulating air due to the urgency of the rescue process and then to decide which filter should be selected for certain substances.
Die Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the accompanying drawing.
Figur 1 zeigt die perspektivische Ansicht einer erfindungsgemäßen Schutzhülle, die als Babytragetasche ausgebildet ist.Figure 1 shows the perspective view of a protective cover according to the invention, which is designed as a baby carrier.
Die Schutzhülle 1 kann mit dem Reißverschluß 2 verschlossen werden. Das im Innenraum 3 der Schutzhülle 1 befindliche Baby ist mit der Außenluft über den Anschluß 4 verbunden. Dieser Anschluß 4 weist ein Rollgewinde auf und ist mit einer Drosseldüse 5 versehen, die zu der Mitteldruckleitung 6 führt. Die Mitteldruckleitung 6 ist über ein Y-Stück 7 mit der Leitung verbunden, die für den Feuerwehrmann vorgesehen ist. Dieses Y-Stück 7 verbindet die Mitteldruckleitung 6 mit dem Druckminderer eines Atemschutzgerätes, so daß dieses Atemschutzgerät über das Y-Stück 7 sowohl den Feuerwehrmann als auch den Innenraum 3 der Schutzhülle 1 mit der notwendigen Atemluft versorgen kann.The protective cover 1 can be closed with the
Befindet sich somit das zu schützende Baby im Innenraum 3 der Schutzhülle 1, so kann dieses auf einfache Weise umluftunabhängig gerettet werden. Der Feuerwehrmann hat sein Atemschutzgerät über das Y-Stück 7 mit der Mitteldruckleitung 6 der Schutzhülle 1 verbunden und kann somit auf einfache Weise das sich in der Schutzhülle 1 befindliche Baby an den Tragegriffen 8 tragen und nach außen bringen. Unabhängig von der Art der in der Umluft befindlichen Schadstoffe und dem Sauerstoffgehalt kann somit das sich in der Schutzhülle 1 befindliche Baby gerettet werden.If the baby to be protected is thus located in the
Die Erfindung sollte jedoch nicht auf die beschriebene Babytragetasche beschränkt werden, da es auch denkbar ist, daß beispielsweise eine zeltartige Schutzhülle verwendet wird, um beispielsweise kurzzeitig mehrere Personen im Innenraum einer derartigen Schutzhülle mit Atemluft zu versehen. Ferner ist die Schutzhülle 1 mit Überdruckventilen 9 versehen, die zum Abführen des Überdrucks in der geschlossenen Schutzhülle dienen.However, the invention should not be limited to the baby carrier described, since it is also conceivable that, for example, a tent-like protective cover is used, for example to briefly provide several people in the interior of such a protective cover with breathing air. Furthermore, the protective cover 1 is provided with pressure relief valves 9 which serve to discharge the excess pressure in the closed protective cover.
