Mobile AtemgasversorgungseinheitMobile breathing gas supply unit
Die Erfindung betrifft eine Vorrichtung mit den Merkmalen des Oberbegriffs des Schutzanspruchs 1.The invention relates to a device having the features of the preamble of claim 1.
Aus der EP 125 447 B1 ist ein Mehrwegventil zur Versorgung eines Piloten mit Atemgas bekannt, welches zwischen einer normalen Sauerstoffversorgung (OBOGS) und einer Notversorgung (BOS) umschaltet. Die Wahl der Gasversorgung kann entweder manuell durch den Piloten vorgenommen werden, oder sie wird automatisch in Abhängigkeit von den Flugbedingungen durchgeführt. So wird beispielsweise, wenn der Beatmungssystemdruck der normalen Sauerstoffversorgung unter einen vorgewählten Pegel absinkt, Atemgas aus der Notversorgung dem Patienten zugeführt. Das bekannte Sauerstoffversorgungssystem ist fest in einem Flugzeug installiert.EP 125 447 B1 discloses a multi-way valve for supplying a pilot with breathing gas, which switches between a normal oxygen supply (OBOGS) and an emergency supply (BOS). The choice of gas supply can either be made manually by the pilot, or it is carried out automatically depending on the flight conditions. For example, if the ventilation system pressure of the normal oxygen supply falls below a preselected level, breathing gas from the emergency supply is supplied to the patient. The known oxygen supply system is permanently installed in an aircraft.
Wenn sich Personen außerhalb des Flugzeuges aufhalten, wie z.B. Fallschirmspringer, müssen sie eine mobile Sauerstoffversorgung mit sich führen, aus der die Atemgasversorgung während des Sprunges erfolgt.If people are outside the aircraft, such as skydivers, they must carry a mobile oxygen supply with them, from which the breathing gas is supplied during the jump.
Bekannte mobile Atemgasversorgungseinheiten beinhalten zwar ein Atemgasreservoir, welches am Mann getragen wird, es ist jedoch keine Kopplung mit dem im Flugzeug befindlichen Atemgasversorgungssystem vorgesehen.Known mobile breathing gas supply units contain a breathing gas reservoir that is worn by the person, but there is no provision for coupling with the breathing gas supply system in the aircraft.

Der Erfindung liegt die Aufgabe zugrunde, eine mobile Atemgasversorgungseinheit derart zu verbessern, daß unterschiedliche, stationär vorhandene Atemgasquellen auf einfache Weise anschließbar sind.The invention is based on the object of improving a mobile breathing gas supply unit in such a way that different, stationary breathing gas sources can be connected in a simple manner.
Die Lösung der Aufgabe erfolgt durch die Kombination der Merkmale einesThe task is solved by combining the features of a
Mehrwegventiles, welches Atemgas wahlweise aus einer mit Atemgas gefüllten Druckgasflasche oder einer bordseitigen AtemgasqueHe einer Person zuführt, wobei während einer ersten Betriebsart die Person Atemgas aus der Druckgasflasche und während einer zweiten Betriebsart aus der bordseitigen AtemgasqueHe erhält,Multi-way valve which supplies breathing gas to a person either from a compressed gas cylinder filled with breathing gas or from an on-board breathing gas source, whereby during a first operating mode the person receives breathing gas from the compressed gas cylinder and during a second operating mode from the on-board breathing gas source,
einer ersten selbstschließenden Schnelltrennkupplung zwischen dem Mehrwegventil und der bordseitigen AtemgasqueHe,a first self-closing quick-release coupling between the multi-way valve and the on-board breathing gas source,
einer zweiten selbstschließenden Schnelitrennkupplung abströmseitig eines dem Mehrwegventil nachgeschalteten Atemdruckreglers, so daß währenda second self-closing quick-release coupling downstream of a breathing pressure regulator connected to the multi-way valve, so that during
einer dritten Betriebsart, wenn eine Niederdruck-Atemgasquelle an die zweite Schnelitrennkupplung angeschlossen ist, die Person ausschließlich mit Gas aus der Niederdruck-Atemgasquelle versorgt wird.a third operating mode, when a low-pressure breathing gas source is connected to the second quick disconnect coupling, the person is supplied exclusively with gas from the low-pressure breathing gas source.
Der Vorteil der Erfindung besteht im wesentlichen darin, daß durch zwei, auf unterschiedliche Druckversorgungsniveaus angepaßte, Schnelltrennkupplungen eine einfache Adaption der Atemgasversorgungseinheit an unterschiedliche Atemgasversorgungssysteme im Flugzeug möglich ist.The advantage of the invention is essentially that two quick-release couplings adapted to different pressure supply levels enable simple adaptation of the breathing gas supply unit to different breathing gas supply systems in the aircraft.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben.An advantageous embodiment of the invention is specified in claim 2.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im folgenden näher erläutert.An embodiment of the invention is shown in the drawing and explained in more detail below.
Die einzige Figur zeigt eine mobile Atemgasversorgungseinheit 1, die aus einer mit Atemgas gefüllten Druckgasflasche 2, einem Mehrwegventil 3 mit einer ersten, selbstschließenden Schnelltrennkupplung 4, einem Atemdruckregler 5 mit einer nachgeschalteten zweiten selbstschließenden Schnelltrennkupplung 6 und einer Atemmaske 7 besteht. Die Druckgasflasche 2 zusammen mit dem Mehrwegventil 3 und der ersten Schnelltrennkupplung 4 sind in einer Halterung 8 aufgenommen, welche an einem in der Figur nicht dargestellten Fallschirmspringer befestigt ist. Das Mehrwegventil 3 enthält einen druckgesteuerten Umschalter 9, in Form eines 3/2 -Wege-Ventils, welches in der in der Figur gezeigten Schaustellung, als einer ersten Betriebsart, die Druckgasflasche 2 mit dem Atemdruckregler 5 verbindet. Sofern während einer zweiten Betriebsart an die erste Schnelltrennkupplung 4 eine bordseitige Atemgasquelle 10, z.B. ein 6-bar Mitteldruck Bordnetz, angeschlossen wird, wird der Umschalter 9 durch den von der Atemgasquelle 10 gelieferten Druck derart betätigt, daß der Atemdruckregler 5 das Atemgas ausschließlich aus der Atemgasquelle 10 erhält. Die Atemgasquelle 10 kann neben dem bordseitigen Sauerstoffnetz auch eine mit Sauerstoff gefüllte, mit einem Druckminderer versehene Druckgasflasche sein. Zusätzlich kann während einer dritten Betriebsart eine Niederdruck-Atemgasquelle 11 an die zweite Schnelltrennkupplung 6 angeschlossen werden, wobei in dieser Betriebsart die Atemgasversorgung ausschließlich aus der Niederdruck-Atemgasquelle bezogen wird. Die Atemgasquelle 10 als auch die Druckgasflasche 2 sind mittels eines abströmseitig des Atemdruckreglers 5 befindlichen Rückschlagventils 12 abgeschaltet. Bei der erfindungsgemäßen Atemgasversorgungseinheit 1The single figure shows a mobile breathing gas supply unit 1, which consists of a compressed gas cylinder 2 filled with breathing gas, a multi-way valve 3 with a first, self-closing quick-release coupling 4, a breathing pressure regulator 5 with a downstream second self-closing quick-release coupling 6 and a breathing mask 7. The compressed gas cylinder 2 together with the multi-way valve 3 and the first quick-release coupling 4 are accommodated in a holder 8, which is attached to a parachutist not shown in the figure. The multi-way valve 3 contains a pressure-controlled switch 9, in the form of a 3/2-way valve, which in the display position shown in the figure, as a first operating mode, connects the compressed gas cylinder 2 to the breathing pressure regulator 5. If, during a second operating mode, an on-board breathing gas source 10, e.g. a 6-bar medium-pressure on-board network, is connected to the first quick-release coupling 4, the changeover switch 9 is actuated by the pressure supplied by the breathing gas source 10 in such a way that the breathing pressure regulator 5 receives the breathing gas exclusively from the breathing gas source 10. In addition to the on-board oxygen network, the breathing gas source 10 can also be a compressed gas bottle filled with oxygen and equipped with a pressure reducer. In addition, during a third operating mode, a low-pressure breathing gas source 11 can be connected to the second quick-release coupling 6, whereby in this operating mode the breathing gas supply is drawn exclusively from the low-pressure breathing gas source. The breathing gas source 10 and the compressed gas bottle 2 are switched off by means of a check valve 12 located on the downstream side of the breathing pressure regulator 5. In the breathing gas supply unit 1 according to the invention
ist die Bewegungsfreiheit des Fallschirmspringers nicht eingeschränkt, da die Atemgasversorgung während des Sprunges aus der Druckgasflasche 2 und beim Aufenthalt im Flugzeug aus der bordeigenen Atemgasversorgung 10,11 bezogen wird. Die bordeigene Atemgasversorgung 10,11 ist dabei an eine der Schnelltrennkupplungen 4, 6 angeschlossen. Auf diese Weise steht das in der Druckgasflasche 2 gespeicherte Atemgas vollständig für den Absprung zur Verfügung.the skydiver's freedom of movement is not restricted, since the breathing gas supply during the jump is taken from the compressed gas bottle 2 and while in the aircraft from the on-board breathing gas supply 10,11. The on-board breathing gas supply 10,11 is connected to one of the quick-release couplings 4, 6. In this way, the breathing gas stored in the compressed gas bottle 2 is completely available for the jump.
