Description

Bezeichnung: AtemmaskeName: breathing mask
Die vorliegende Erfindung betrifft eine Atemmaske zur Beatmung von Menschen.The present invention relates to a breathing mask for breathing humans.
Eine Vielzahl von Personen, vor allem Männer, leiden an einem nächtlichen Aussetzen der Atmung, das im Extremfall sogar lebensbedrohliche Ausmaße annehmen kann. Bei dieser sogenannten Apnoe kann ein Beatmungsgerät Abhilfe schaffen, das zur Nacht getragen wird.A large number of people, especially men, suffer from nightly breathing interruptions, which in extreme cases can even be life-threatening. A ventilator that can be worn at night can help with this so-called apnea.
Die Krankheit findet ihre Ursachen in einer Erschlaffung des Rachenmuskelgewebes und führt neben einer Unterversorgung mit lebensnotwendigem Sauerstoff oftmals auch zu Problemen mit dem jeweiligen Lebenspartner infolge der hierdurch auftretenden Potenzstörungen. Die einzelnen Aussetzphasen der Atmung dauern dabei etwa zwischen zehn Sekunden und einer Minute.The disease is caused by a slackening of the pharynx muscle tissue and, in addition to an undersupply of essential oxygen, often also leads to problems with the partner in question as a result of the resulting erectile dysfunction. The individual suspension phases of breathing last between about ten seconds and one minute.
Eine Lösung dieses Problems kann in der Verwendung eines Atmungsgerätes mit Atemmaske bestehen. Dabei handelt es sich hier um eine Apparatur, die nach dem sogenannten CP AP- Verfahren (Continous Positive Air Pressure) arbeitet und den Patienten mittels eines leichten Überdrucks über eine Schlauchzuführung und eine nächtens anzulegende Gesichtsmaske mit druckbeaufschlagter Luft versorgt. Dabei finden Drücke von etwa bis zu 16 Millibar Verwendung.One solution to this problem can be to use a respirator with a breathing mask. This is an apparatus that works according to the so-called CP AP method (Continous Positive Air Pressure) and supplies the patient with pressurized air by means of a slight overpressure via a hose feed and a face mask to be put on at night. Pressures of up to 16 millibars are used.
Derartige Geräte werden etwa von der Firma Respironics Inc., 1001 Murry Ridge Drive, Murrysville, Pa. 15668-8550, Vereinigte Staaten von Amerika angeboten.Such devices are available from Respironics Inc., 1001 Murry Ridge Drive, Murrysville, Pa. 15668-8550, United States.
Weiterhin sind Geräte der Firma Gottlieb Weinmann Geräte für Medizin und Arbeitsschutz GmbH + Co., Hamburg unter der geschützten Marke SOMNOTRON®2 nCPAP-Schlaf- Apnoe-Sets auf dem Markt erhältlich. Die Firma Winmann verwendet dabei das Somno- Maskensystem, bei dem anstelle der bis dahin bekannten Auslaßschlitze eine Kunststoff- Filterpatrone in dem zur Maske führenden Frischluftschlauch eingesetzt wird ist. Diese Fil- terpratone besteht aus einem Keramikfilter und ist als Austauschteil sehr kostenintensiv. Zudem ist die Patrone derart in einem Bereich des Zuluft -Schlauches angeordnet, daß die zugeführte Frischluft bzw. die ausgeatmete Atemluft dem Benutzer ins Gesicht blasen kann, was dem Tragekomfort der Vorrichtung abträglich ist.Devices from Gottlieb Weinmann devices for medicine and occupational safety GmbH + Co., Hamburg, are also available on the market under the protected trademark SOMNOTRON ® 2 nCPAP sleep apnea sets. The Winmann company uses the Somno Mask system in which a plastic filter cartridge is used in the fresh air hose leading to the mask instead of the previously known outlet slots. This filter cartridge consists of a ceramic filter and is very expensive to replace as a replacement part. In addition, the cartridge is arranged in a region of the supply air hose in such a way that the fresh air supplied or the exhaled breathing air can blow into the face of the user, which is detrimental to the comfort of the device.
All diesen Geräten sind jedoch Probleme zu eigen, die ihre Verwendung erheblich erschweren oder gar zu verhindern vermögen. So sind die jeweiligen Geräte trotz der Verwendung von Schalldämpfern immer noch relativ laut und stören somit sowohl den Patienten selbst wie auch seinen Lebenspartner. So ist es beim nächtlichen Verlassen des Betts erforderlich, zur Vermeidung störender Luftgeräusche zunächst das gesamte Gerät außer Funktion zu setzen, was für den Verwender ausgesprochen lästig ist. Darüber hinaus vertragen viele Patienten die Gesichtsmasken aufgrund ihres geringen Tragekomforts nicht. In schwereren Fällen führen sie sogar zu Hauterkrankungen und Hautallergien.However, all of these devices have problems which make their use considerably more difficult or even prevent them. So despite the use of silencers, the respective devices are still relatively loud and thus disturb both the patient himself and his life partner. So when leaving the bed at night, it is necessary to first put the entire device out of order to avoid disturbing air noise, which is extremely annoying for the user. In addition, many patients cannot tolerate the face masks due to their low wearing comfort. In more severe cases, they even lead to skin diseases and skin allergies.
Speziell diesem Problem widmet sich ein Lösungsvorschlag der bereits angeführten Firma Respironics Inc., die eine Silikon Kontur Maske anbieten, die aufgrund des verwendeten Silikonmaterials hautfreundlicher ist als herkömmliche Masken mit Gummidichtungen. Jedoch kann dieser Lösungsvorschlag immer noch nicht als ausreichend angesehen werden. Insbesondere im Randbereich weisen derartige Silikon Kontur Masken immer noch recht scharfe oder zumindest abrupt ausgestaltete Verläufe auf, die für den Patienten störend wirken können.A solution proposed by Respironics Inc., which has already been mentioned, addresses this problem in particular. They offer a silicone contour mask that is more skin-friendly than conventional masks with rubber seals due to the silicone material used. However, this proposed solution can still not be considered sufficient. In the edge area in particular, such silicone contour masks still have very sharp or at least abruptly shaped courses which can be disruptive to the patient.
Insgesamt kann festgehalten werden, daß nach dem Stand der Technik keine CP AP- Beatmungsgeräte bekannt sind, die Atemmasken mit etwaigem Zubehör zur Verfügung stellen, welche eine ausreichende Berücksichtigung des Tragekomforts und auch der Geräuschentwicklung während ihrer Verwendung erkennen lassen.All in all, it can be stated that no CP AP ventilators are known in the prior art which provide breathing masks with any accessories which allow sufficient attention to be paid to the wearing comfort and also to the noise development during their use.
Daher ist es Aufgabe der vorliegenden Erfindung eine Atemmaske mit derartigen Trage - komforteigenschaften anzugeben. Diese Aufgabe wird durch eine Atemmaske gelöst, die durch eine oder mehrere der nachfolgenden erfindungsgemäßen Vorrichtungen gekennzeichnet ist, nämlich eine Befestigungsvorrichtung eines Befestigungsbandes zur andruckmindernden Anbringung der Atemmaske auf dem menschlichen Gesicht mit Befestigungsband, einen schallgedämpften Luftauslaß, ein Luftzufuhrverbindungsstück, sowie eine Maskendichtung zum dichten aber hautverträglichen Kontakt der Maske zum menschlichen Gesicht.It is therefore an object of the present invention to provide a breathing mask with such comfort properties. This object is achieved by a breathing mask, which is characterized by one or more of the following devices according to the invention, namely a fastening device of a fastening tape for pressure-reducing attachment of the breathing mask to the human face with fastening tape, a soundproofed air outlet, an air supply connection piece, and a mask seal for sealing but skin-friendly contact of the mask with the human face.
Die Befestigungsvorrichtung eines Befestigungsbandes zur andruckmindernden Anbringung der Atemmaske auf dem menschlichen Gesicht mit Befestigungsband ist dabei erfindungsgemäß dadurch gekennzeichnet, daß die sie einen Waagebalken aufweist, der zum einen in etwa mittig über Gelenke mit der Atemmaske und zum anderen randseitig über Anknüpfungspunkte mit dem Befestigungsband verbunden ist. Bei den Atemmasken nach dem Stand der Technik sind an der eigentlichen Maske seitlich starr angeformte Halterungen vorgesehen, an die zwei seitliche Kopfbänder zur Befestigung angeschlossen werden. Dies führt zwangsläufig bei unwillkürlichen Kopfbewegungen während des Schlafs zu einem Verrutschen der Maske. Dem kann nur durch erhöhten Anpreßdruck der Make begegnet werden, was wiederum zu Hautproblemen führt.The fastening device of a fastening band for the pressure-reducing attachment of the breathing mask on the human face with fastening band is characterized in accordance with the invention in that it has a balance beam which is connected to the breathing mask approximately centrally via joints and on the other hand to the fastening band at the edge via attachment points . In the case of the breathing masks according to the prior art, rigid mounts are provided on the side of the actual mask, to which two lateral headbands are connected for fastening. This inevitably leads to the mask slipping if the head moves involuntarily while sleeping. This can only be countered by increasing the contact pressure, which in turn leads to skin problems.
Erfindungsgemäß werden hier nun die seitlichen Kopfbänder so an die Atemmaske angeschlossen, daß die Kraft von den Kopfbändern zentral in den Bereich der Nase, d.h. etwa im Bereich des Nasenrückens eingeleitet wird. Dies leistet der mindestens eine Waagebalken, der zentral an der Maske gelenkig angeschlossen wird, so daß die Maske pendelnd an dem Waagebalken abgestützt ist. Ein Kippen der Maske gegenüber dem Gesicht ist somit ausgeschlossen, ebenso wie ein seitlches Verrutschen. Die Andruckkräfte können gering sein, womit auch eine Verringerung der Hautprobleme einhergeht.According to the invention, the side headbands are now connected to the breathing mask in such a way that the force from the headbands is central to the area of the nose, i.e. about in the area of the bridge of the nose. This is achieved by the at least one balance beam, which is pivotally connected centrally to the mask, so that the mask is supported on the balance beam in an oscillating manner. Tilting of the mask against the face is therefore impossible, as is slipping sideways. The pressure forces can be low, which is accompanied by a reduction in skin problems.
In einer Ausführungsform nach der vorliegenden Erfindung kann der Waagebalken auch über genau ein Gelenk an der Atemmaske angelenkt sein.In one embodiment according to the present invention, the balance beam can also be articulated on the respiratory mask via exactly one joint.
Vorzugsweise handelt es sich es sich im Falle der Gelenke um Universal- oder Kugelgelenke, die in alle Richtungen auslenkbar sind, denn die Abstützung des vorgenannten Waagebalkens soll so erfolgen, daß nicht nur eine horizontale Schwenkung, sondern bedingt auch eine vertikale Schwenkung des Waagebalkens gegenüber dem Abstützpunkt möglich ist.In the case of the joints, it is preferably universal or ball-and-socket joints which can be deflected in all directions, because the above-mentioned balance beam should be supported in such a way that not only horizontal pivoting, but also conditionally vertical pivoting of the balance beam with respect to the support point is possible.
Der erfindungsgemäße schallgedämpfte Luftauslaß ist dadurch gekennzeichnet, daß der Luftauslaß einen Schalldämpfer aus offenporigem Schaumstoff aufweist. Dieser kann dabei mit einem Mantel, vorzugsweise aus Kunststoff umgeben sein.The sound-damped air outlet according to the invention is characterized in that the air outlet has a silencer made of open-cell foam. This can be surrounded by a jacket, preferably made of plastic.
Der Schalldämpfer kann im Bereich der Atemmaske ein- oder aufgesetzt werden, oder auch den Zuluftschlauch an einer perforierten Stelle des Schlauches klemmenartig umgeben. Vorzugsweise ist ein separates Gehäuse für den Schalldämpfer vorgesehen, insbesondere ein einseitig offenes Rohr, das mit dem Zuluftbereich verbunden ist. Ein solcher Schalldämpfer, etwa aus einem Kunststoffmantel, in den ein preiswerter feinporiger Schaumstoffpfopfen eingesetzt ist, kann bei Bedarf ausgewechselt oder auch gereinigt werden. Der Austritt der Atemluft erfolgt weiter weg vom Gesicht und wirkt deshalb weniger störend. Störende Geräusche werden durch ihn weitgehend eliminiert.The muffler can be inserted or attached in the area of the breathing mask, or it can also surround the supply air hose at a perforated point in the hose. A separate housing for the muffler is preferably provided, in particular a pipe which is open on one side and is connected to the supply air area. Such a silencer, for example made of a plastic jacket, into which an inexpensive, fine-pored foam plug is inserted, can be replaced or cleaned if necessary. The air exhales further away from the face and is therefore less disruptive. It largely eliminates disturbing noises.
Das Luftzufuhrverbindungsstück zwischen Atemmaske und Luftversorgungssystem nach der vorliegenden Erfindung ist dadurch gekennzeichnet, daß es im Bereich des Kopfes dort auf einem Befestigungshalter verschiebbar angeordnet ist.The air supply connector between the breathing mask and the air supply system according to the present invention is characterized in that it is slidably arranged on a mounting bracket in the region of the head.
In einer bevorzugten Ausführungsform ist es dabei vom dem zum Luftversorgungssystem hin gehenden Zuluftschlauch lösbar ausgestaltet.In a preferred embodiment, it is designed to be detachable from the supply air hose going to the air supply system.
Die Vorrichtung nach der vorliegenden Erfindung ermöglicht es so beispielsweise bei kürzerer Schlafunterbrechung die Atemmaske aufzubehalten, wobei lediglich der Zuluftschlauch gelöst werden muß. Dies erleichtert die Verwendung erheblich.The device according to the present invention thus makes it possible, for example, to keep the breathing mask open during a shorter sleep interruption, only the supply air hose having to be loosened. This makes it much easier to use.
Dabei wird der Zuluftschlauch über eine Peitschenhalterung am Bett zu einem auf einem Befestigungshalter, vorzugsweise auf einer Kopfhaube befestigten, verstellbaren, insbesondere verschiebbaren Luftzufuhrverbindungsstück zur Maske geführt. Das Luftzufuhrverbindungsstück besteht aus einem Drehadapter, einem Schnellverschluß, einer automatischen Absperrklappe und fixiert die Maskenposition. Möchte man in der Nacht aufstehen, wird per Knopfdruck der Zuluftschlauch getrennt und gleichzeitig verschließt eine Klappe den Luftstrom. Wieder im Bett, wird der an der Peitschenhalterung hängende Zuluftschlauch durch einfaches Zusammenstecken wieder angeschlossen, gleichzeitig öffnet sich die Verschlußklappe.The supply air hose is guided via a whip holder on the bed to an adjustable, in particular displaceable, air supply connection piece attached to a mounting bracket, preferably on a head cover, to the mask. The air supply connector consists of a rotary adapter, a quick release, an automatic shut-off valve and fixes the mask position. If you want to get up at night, the supply air hose is disconnected at the push of a button and at the same time a flap closes the air flow. Back in bed, the supply air hose hanging on the whip holder becomes reconnected by simply plugging it in, the flap opens at the same time
Die Maskendichtung zum dichten aber hautverträglichen Kontakt der Maske zum menschlichen Gesicht ist erfindungsgemäß dadurch gekennzeichnet, daß die Dichtung als Silikonschlauch ausgebildet ist, der zumindest teilweise mit einem geleeartigen nachgiebigen Stoff gefüllt ist.According to the invention, the mask seal for the tight but skin-friendly contact of the mask with the human face is characterized in that the seal is designed as a silicone tube which is at least partially filled with a jelly-like compliant material.
Die Füllung des Silikonschlauches erfolgt vorzugsweise zu höchstens 75 %, idealerweise zur Hälfte mit dem geleeartigen Material.The silicone tube is preferably filled to a maximum of 75%, ideally half with the jelly-like material.
Der Silikonschlauchmantel ist in einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung zur Maske hin dicker als zur abzudichtenden Hautpartie hin ausgestaltet.In a further preferred embodiment of the present invention, the silicone tube jacket is made thicker towards the mask than towards the skin area to be sealed.
Atemmasken nach der vorliegenden Erfindung bieten demnach eine neuartige, flexible und zug- andruckausgleichende Befestigungstechnik. Schon bei einem minimalen Anpaßdruck bekommt die Maske einen festen Halt. Hautverletzungen oder Druckstellen an der Nase, Stirn und Wangen entfallen.Respiratory masks according to the present invention therefore offer a novel, flexible and tension-compensating fastening technique. Even with a minimal adjustment pressure, the mask gets a firm hold. Skin injuries or pressure points on the nose, forehead and cheeks are eliminated.
Die Atemmaske verdreht und verschiebt sich nicht durch Luftschlauchzerrungen, auch hebt sie sich nicht einseitig ab und verursacht somit keine Luftaustrittsgeräusche, wodurch Augen- und Ohrenreizungen infolge von Nebenlu taustritt verhindert werden.The breathing mask does not twist or shift due to air hose strains, nor does it lift off on one side and therefore does not cause air leakage noises, which prevents eye and ear irritation due to secondary air leakage.
Die erfindungsgemäße Atemmaske weist einen rundum gleichmäßigen Anpaßdruck auf, der auch bei seitlichen Kopfbewegungen konstant bleibt. Mit zwei Handgriffen läßt sich der Maskenkörper aus der Befestigung problemlos lösen. Eine schnelle Reinigung ist ebenso unproblematisch, da der Maskenkörper einschließlich Dichtprofil glatt und nahtlos ist und keinen Raum für "Bakterienbrutstätlen" aufweist.The breathing mask according to the invention has an all-round, uniform adjustment pressure, which remains constant even when the head is moved sideways. The mask body can be easily removed from the attachment in two easy steps. Quick cleaning is also not a problem, since the mask body including the sealing profile is smooth and seamless and has no room for "bacterial hatching".
Die zur Abdichtung allgemein gebräuchlichen Maskenwulste und die hautdurchblutungsstö- renden, nasenumschließenden Dichthäute werden durch ein schmales, glattes, rundumlaufendes Silikon-Hohlprofil, das nur zum Teil unter Luftabschluß mit Gel befüllt ist, ersetzt. Dieses flexible Hohlprofil paßt sich dem Nasenumfeld problemlos an. Selbst im Dichtbereich befindliche Warzen etc. werden mühelos abgedeckt. Die Ausblasluft fließt durch Öff- nungen im Maskenwinkel über einen „Huckepack-Schalldämpfer" mit austauschbarem, pfropfenähnlichem Filter fast lautlos ab.The mask beads, which are generally used for sealing, and the sealing skins that interfere with the circulation of the skin, are replaced by a narrow, smooth, all-round silicone hollow profile, which is only partially filled with gel to exclude air. This flexible hollow profile adapts easily to the area around the nose. Even warts etc. in the sealing area are covered effortlessly. The exhaust air flows through cuts in the mask angle almost silently using a "piggyback silencer" with an exchangeable plug-like filter.
Durch die Verwendung der erfindungsgemäßen Atemmaske wird eine Vielzahl der bislang bekannten Probleme bei der Verwendung von CPAP-Systemen gemindert oder gar aufgehoben. Die erfindungsgemäßen Atemmasken sorgen für einen gemeinsamen, partnerfreundlichen, störungsfreien Schlaf.By using the breathing mask according to the invention, a large number of the previously known problems when using CPAP systems are reduced or even eliminated. The breathing masks according to the invention ensure a common, partner-friendly, trouble-free sleep.

Fig. 1 zeigt eine schematische Darstellung einer liegenden Person, die eine erfindungsgemäße Atemmaske, die in den Figuren 1A bis IC noch deutlicher dargestellt ist, trägt, in Seitenansicht. Die Atemmaske ist dabei hier mit zwei Befestigungsvorrichtungen zur andruckmindernden Anbringung der Atemmaske auf dem menschlichen Gesicht jeweils nach Art eines Waagebalkens 30 versehen, der zum einen über Universalgelenke 1 mit der Atemmaske und zum anderen über Anknüpfungspunkte 31 mit dem Befestigungsband 32 verbunden ist. Auf dem Zuluftschlauch 33 sitzt dabei ein schallgedämpfter Luftauslaß 2 im Bereich der Atemmaske. Die beiden Waagebalken 30 können mechanisch miteinander verbunden sein.Fig. 1 shows a schematic representation of a person lying down, wearing a breathing mask according to the invention, which is shown even more clearly in Figures 1A to IC, in side view. The breathing mask is here provided with two fastening devices for the pressure-reducing attachment of the breathing mask to the human face, each in the manner of a balance beam 30, which is connected on the one hand to the breathing mask via universal joints 1 and on the other hand to the fastening strap 32 via attachment points 31. A sound-damped air outlet 2 sits on the supply air hose 33 in the area of the breathing mask. The two balance beams 30 can be mechanically connected to one another.
Fig. 2 zeigt eine schematische Darstellung einer Atemmaske nach der vorliegenden Erfindung im Längsschnitt. Die Atemmaske ist auch hier mit zwei Befestigungsvorrichtungen zur andruckmindernden Anbringung der Atemmaske auf dem menschlichen Gesicht jeweils nach Art eines Waagebalkens versehen, die über Gelenke 1 mit der Atemmaske verbunden sind. Auf dem Zuluftschlauch 33 sitzt dabei ein schallgedämpfter Luftauslaß 2 im Bereich der Atemmaske. Die leicht druckbeaufschlagte Luft strömt dabei in Pfeilrichtung 36 zur eigentlichen Atemmaske 34 hin, wo sie das Einatmen unterstützt. Beim Ausatmen strömt die Luft alsdann durch den Schalldämpfer 2 in Pfeilrichtung 37 aus. Die eigentliche Atemmaske 34 liegt über einen Silikonschlauch 20 dicht am Gesicht an, so daß keine Nebenluft ausströmen kann.Fig. 2 shows a schematic representation of a breathing mask according to the present invention in longitudinal section. Here, too, the breathing mask is provided with two fastening devices for the pressure-reducing attachment of the breathing mask to the human face, each in the manner of a balance beam, which are connected to the breathing mask via joints 1. A sound-damped air outlet 2 sits on the supply air hose 33 in the area of the breathing mask. The slightly pressurized air flows in the direction of arrow 36 towards the actual breathing mask 34, where it supports inhalation. When exhaling, the air then flows out through the muffler 2 in the direction of the arrow 37. The actual breathing mask 34 lies tightly against the face via a silicone tube 20, so that no secondary air can flow out.
Fig.2A zeigt eine schematische Darstellung einer Befestigungsvorrichtung der Atemmaske nach der vorliegenden Erfindung in Form eines Waagebalkens im Querschnitt. Die Atemmaske 34 ist dabei mit dem sogenannten Waagebalken 30 über ein Gelenk 1 beweglich verbunden. Der Waagebalken selbst 30 ist seinerseits über Anknüpfungspunkte 31 mit dem elastischen, flexiblen Kopfband 32 verbunden, welches den Kopf 35 umschließt.2A shows a schematic illustration of a fastening device of the breathing mask according to the present invention in the form of a balance beam in cross section. The breathing mask 34 is movably connected to the so-called balance beam 30 via a joint 1. The balance beam itself 30 is in turn connected to the elastic, flexible headband 32, which encloses the head 35, via attachment points 31.
Fig.3 zeigt eine schematische Darstellung eines Luftzufuhrverbindungsstücks 40 nach der vorliegenden Erfindung im Längsschnitt und die Figuren 4 und 4A dieses Stück 40 im Querschnitt. Beide werden im folgenden gemeinsam besprochen. Dabei ist für die Auflage auf der Stirn und insbesondere oberhalb dieser eine Kopfband- Anschlußplatte 38 vorgesehen, in deren Bereich eine Art Winkel- oder Riegelkonsole 3 angeordnet ist, an der der horizontale Schenkel mit dem Kopfband 4 in Pfeilrichtungen 5 in verschiedenen Position, vorzugsweise mittels eines Riegels 6 festlegbar ist. Der Zuluftschlauch 7 oder 33 ist über einen Drehadapter 8 mit einem aushebbaren Zwischenstück 9 gekoppelt, welches z. B. in einer Schienenführung 10 der Winkelkonsole 3 in Pfeilrichtung 11 aus der Winkelkonsole 3 heraushebbar ist oder anderweitig entkoppelt werden kann. Hierzu ist unter dem aushebbaren Zwischenstück 9 eine Auswurffeder 12 angeordnet, welche das Zwischenstück 9 automatisch aus der Winkelkonsole 3 herausdrückt, wenn hierzu die Schnappverschlüsse 13 betätigt werden.Fig. 3 shows a schematic representation of an air supply connector 40 according to the present invention in longitudinal section and Figures 4 and 4A of this piece 40 in cross section. Both are discussed together below. A headband connecting plate 38 is provided for the support on the forehead and in particular above it, in the area of which a kind of angle or locking bracket 3 is arranged, on which the horizontal leg with the headband 4 in the direction of the arrows 5 in a different position, preferably by means of a bolt 6 can be fixed. The supply air hose 7 or 33 is coupled via a rotary adapter 8 with a removable intermediate piece 9, which, for. B. in a rail guide 10 of the angle bracket 3 in the direction of arrow 11 from the angle bracket 3 can be lifted or otherwise decoupled. For this purpose, an ejector spring 12 is arranged under the removable intermediate piece 9, which automatically pushes the intermediate piece 9 out of the angle bracket 3 when the snap locks 13 are actuated for this purpose.
In dem aushebbaren Zwischenstück 9 ist eine Absperrklappe 14 vorgesehen, die in Drehrichtung um die axiale Achse 15 mittels einer Feder 16 vorgespannt ist. Die Vorspannung erfolgt so, daß bei eingesetztem Zwischenstück - d.h. wie in Fig. 3 zu sehen, die Absperrklappe 14 in Öffnungsrichtung ausgerichtet ist. Dies erfolgt beim Einsetzen des Zwischenstückes in die Winkelkonsole 3 automatisch dadurch, daß ein an dem Achszapfen 17 drehfest angeordneter Steuernocken 18 an der .Steuerkurve 19 der Winkelkonsole 3 entlangelei- tet. Die Absperrklappe 14 ist damit automatisch in ihrer Lage fixiert, sie ist geöffnet.In the removable intermediate piece 9, a butterfly valve 14 is provided, which is biased in the direction of rotation about the axial axis 15 by means of a spring 16. The pretensioning is carried out so that when the intermediate piece is inserted - i.e. As can be seen in Fig. 3, the butterfly valve 14 is aligned in the opening direction. This takes place automatically when the intermediate piece is inserted into the angle bracket 3 in that a control cam 18 arranged on the axle journal 17 in a manner fixed against relative rotation passes along the control curve 19 of the angle bracket 3. The butterfly valve 14 is thus automatically fixed in its position, it is open.
Beim Ausheben des Zwischenstückes 9 verbringt die Feder 16 die Absperrklappe 14 automalisch in die Schließposition so daß keine Luft aus dem Zuluftschlauch 7 oder 33 entweichen kann. Es ist deshalb nicht erforderlich, das Luftversorgungssystem abzustellen.When lifting the intermediate piece 9, the spring 16 automatically moves the butterfly valve 14 into the closed position so that no air can escape from the supply air hose 7 or 33. It is therefore not necessary to shut down the air supply system.
Fig.5, 5A und 5B zeigen Maskendichtungen nach der vorliegenden Erfindung, jeweils im Querschnitt. Hier findet als unmittelbarer Abschluß der Maske an das Nasen-Umfeld ein Silikonschlauch 20 Verwendung, der in dem mit 21 bezeichneten Bereich relativ dickwandig und in dem mit 22 bezeichneten, auf dem Gesicht aufliegenden Bereich realtiv dünnwandig ausgebildet ist. Dieser Silikonschlauch 20 wird mit einem geleeartigen Material 39, vorzugsweise wiederum Silikon entsprechender Konsistenz gefüllt und anschließend zum Teil unter Vakuum gesetzt, so daß sich die in der Fig. 5B dargestellte Foπn ergibt. Diese Formgebung entsteht aufgrund der über den Kreisumfang gesehenen unterschiedlichen Wanddicke des Silikonschlauches 20. Die Maskendichtung hat ein Halteprofil, mit der sie ein eine Nut oder dergleichen der Maske 34 dicht eingreift.5, 5A and 5B show mask seals according to the present invention, each in cross section. Here, a silicone tube 20 is used as the direct closure of the mask to the nose area, which is relatively thick-walled in the area designated by 21 and relatively thin-walled in the area designated by 22, which rests on the face. This silicone tube 20 is filled with a jelly-like material 39, preferably again silicone of a corresponding consistency, and then partially placed under vacuum, so that the film shown in FIG. 5B results. This shape arises due to the different wall thickness of the silicone tube 20 seen over the circumference of the circle. The mask seal has a holding profile with which it a tightly engages a groove or the like of the mask 34.
Fig.5C zeigt ein bei entsprechendem Bedarf in die Maskendichtung einsetzbares Ausgleichskissen 24 zur weiter verbesserten Anpassung des Silikonschlauches an die menschliche Gesichtsphysiognomie.5C shows a compensating cushion 24 that can be inserted into the mask seal if required, for further improved adaptation of the silicone tube to the human facial physiognomy.
Die Atemmaske ist mit zwei Befestigungsvorrichtungen zur andruckmindernden Anbringung der Atemmaske auf dem menschlichen Gesicht jeweils nach Art eines Waagebalkens versehen, die über Gelenke 1 mit der Atemmaske 34 verbunden sind. Auf dem Zuluftschlauch 7, 33 sitzt dabei ein schallgedämpfter Luftauslaß 2 im Bereich der Atemmaske. Die leicht druckbeaufschlagte Luft strömt in Pfeilrichtung 36 zur eigentlichen Atemmaske 34 hin, wo sie das Einatmen unterstützt. Beim Ausalmen strömt die Luft alsdann durch den Schalldämpfer 2 in Pfeilrichtung 37 aus. Der Schalldämpfer hat ein rohrförmiges Gehäuse, das zum Pfeil 37 hin offen ist und am anderen Ende mit dem Innenraum der Atemmaske über einen Kanal verbunden ist. Der Schalldämpfer hat einen zylindrisch geformten Schaumstoff ilter, der reibschlüssig hält und leicht entfernt werden kann. Die eigentliche Atemmaske 34 liegt über einen Silikonschlauch 20 dicht am Gesicht an, so daß keine Nebenluft ausströmen kann. The breathing mask is provided with two fastening devices for pressure-reducing attachment of the breathing mask on the human face, each in the manner of a balance beam, which are connected to the breathing mask 34 via joints 1. A sound-damped air outlet 2 is located on the supply air hose 7, 33 in the area of the breathing mask. The slightly pressurized air flows in the direction of arrow 36 towards the actual breathing mask 34, where it supports inhalation. The air then flows out through the muffler 2 in the direction of the arrow 37 during the exhalation. The muffler has a tubular housing which is open towards the arrow 37 and is connected at the other end to the interior of the breathing mask via a channel. The muffler has a cylindrical foam filter that holds frictionally and can be easily removed. The actual breathing mask 34 lies tightly against the face via a silicone tube 20, so that no secondary air can flow out.
