Definitions
- Anti-snoring device procedures for reducing snoring and air glasses
- the invention relates to an inexpensive device and a method for reducing snoring and air glasses.
- Obstructive breathing disorders lead to apneas (respiratory arrest), through which the sleeper awakens. Frequent apneas prevent the sleeper from falling into a restful deep sleep. People who suffer from apneas while sleeping are therefore not well rested during the day, which can lead to social problems at work and, in the worst case, fatal accidents, for example for professional drivers.
- CPAP continuous positive airway pressure
- CPAP therapy In CPAP therapy, a patient is fed a constant positive pressure through a nasal mask. If the overpressure is selected correctly, this ensures that the upper respiratory tract remains fully open throughout the night and thus no obstructive breathing disorders occur.
- the pressure required depends, among other things, on the stage of sleep and the body position of the sleeper.
- a therapy device AutoCPAP is known from DE 198 49 571 A1, which automatically adjusts the ventilation pressure and thus adapts to the sleep stage and the body situation.
- Oxygen glasses for oxygen treatment are also known from the prior art. With the oxygen goggles, air with an increased oxygen partial pressure (> 210 mbar) or pure oxygen is applied to the patient's nose. Oxygen treatment takes place, for example, for acute or chronic hypoxemia due to respiratory or cardiovascular disorders (myocardial infarction, shock) or certain poisonings, for example through carbon monoxide, carbon dioxide, luminous gas or smoke. Finally, it is known to treat racing horses with humidified air after the race. The humidified air is conducted into the horse's nostrils through a device similar to oxygen goggles, but adapted to the shape of the horse's head. Due to the high breath volume during a race, the horse's nasal mucosa is unable to secrete sufficient moisture, so that the nasal mucosa dries out.
- the object of the invention is to provide an inexpensive and comfortable device and a method for reducing snoring as well as air glasses.
- An advantage of using an anti-snoring device according to claim 1 in people who snore but do not suffer from pathological apneas is that the anti-snoring device manages with a lower flow compared to devices for CPAP therapy, and thus a smaller compressor is used can.
- the air goggles offer increased wearing comfort and an increased standard of safety, since due to the only partial occlusion of the nose, normal breathing through the nose is ensured even if the turbine in the compressor fails.
- a humidifier prevents the sleeping mucous membranes from drying out, thus increasing comfort.
- the compressor is acoustically optimized.
- the anti-snoring device is preferably equipped with a long hose so that the compressor can be installed in a neighboring room.
- the air flow can advantageously be controlled at three points: by the turbine speed, by a throttle valve and / or by a bypass valve.
- An advantage of the control of the turbine speed is that the compressor low speed and low pressure difference causes less noise.
- controlling the air flow via the turbine speed with the throttle valve open or absent and the bypass valve closed or absent leads to the lowest noise generation by the compressor.
- a throttle valve or a bypass valve can be used as inexpensive options for regulating the air flow in the vicinity of the sleeping person.
- An advantage of a throttle valve is that it reduces the air flow through the compressor and thus the power consumption of the compressor.
- Bypass valves that cannot be regulated are known from CPAP therapy. There they are necessary to enable the patient to exhale despite the face mask being put on.
- An advantage of using a hose with a small inner diameter and a small outer diameter of preferably 4 or 6 mm is the frequent use and thus the inexpensive procurement of such hoses.
- An advantage of the arrangement of the humidifier in the vicinity of the sleeping person is the possibility to set the temperature of the water bath from the bed and to refill the water from the bed.
- a humidifier does not generate any running noise, so placing it next to the bed is not a problem.
- An advantage of air goggles that are largely sealed with the sleeping person's nose is that the air resistance of the bypass does not depend on the remaining opening between the nose and air goggles, but can be adjusted precisely through the defined size of openings in the air goggles.
- An advantage of air glasses equipped with preferably two jacket tubes is that such air glasses require less air flow, so that the pressure drop in the supply hoses is reduced.
- Another advantage of using a jacket tube is that the patient's nostrils are not closed, but rather a defined cross section remains unlocked, so that the patient can breathe in and out through the jacket tubes even if the compressor fails.
- the advantage of using a measuring tube 26 is that it allows the pressure generated by the air glasses in the patient's airways to be measured. Such a measurement makes it possible to detect inhalation and exhalation of the patient and to increase the air flow through the nozzle and thus the pressure generated by the air glasses in the patient's nose during inhalation and to decrease it during exhalation.
- Fig. 3 shows a section through air glasses equipped with jacket tubes
- Fig. 4 equipped with two jacket tubes air glasses.
- Snoring is caused by intermittent vibrations of the sagging soft palate during sleep, when the lower jaw and the tongues have sunk downwards as a result of a loss of tension in the jaw and tongue muscles. This is called obstacle snoring designated. In addition, snoring can also arise as a result of habit formation (common snoring).
- the objects of the invention are intended for people who snore but do not suffer from pathological apneas.
- Fig. 1 shows a sleeping person 14, in whose nose 1 air is applied via air glasses.
- This air provides a slightly increased air pressure in the respiratory tract of the sleeping person, i.e. by 2 to 20 mbar. This slight excess pressure leads to an expansion of the airways. This counteracts the lowering of the lower jaw and the lowering of the tongue.
- the air goggles essentially consist of two tubes that are led back over the ears. Both hoses are brought together in a Y-switch 12 to form a hose. Furthermore, a sliding ring 13 is provided in order to adapt the air glasses to the head size of the sleeper. As an alternative to the wearing method shown in FIG. 1, the two tubes cannot be brought together behind the ears, but around the ears and then below the lower jaw, as shown in broken lines in FIG. 1.
- the tube 11 between the compressor 2 or air humidifier 6 and the Y switch 12 has an inner diameter of less than 10 mm, for example 4 mm, and an outer diameter of less than 12 mm, at 6 mm.
- the tube pieces between the patient's nose and the Y-switch 12 have, for example, an inner diameter of also less than 10 mm, e.g. of 3 mm and an outside diameter of less than 12, e.g. 5 mm. Due to these small cross sections, the pressure drop in the hoses is noteworthy.
- the compressor 2 should therefore be able to generate an overpressure of 100 to 1000 mbar compared to the ambient pressure. The larger the diameter of the hose pieces are chosen, the lower the pressure generated by the compressor can be.
- the outlets of the air goggles can - as is usual with oxygen goggles - be smaller than the nostrils of the sleeping person.
- the sleeper can go through Exhale the gap between the outlets and the nasal cannula. This gap forms a non-controllable bypass, so to speak.
- the outlets of the air glasses can be adapted to the shape of the nostrils, so that they are largely sealed with the nostrils.
- openings 15 for breathing out can be provided in the air goggles, which can be supplemented by sliding or rotating elements to form a controllable valve.
- the compressed air is generated by a compressor 2.
- the compressor 2 is acoustically optimized.
- it has sound insulation 4.
- a turbine controller 5 is provided so that the turbine 3 runs in the compressor at the lowest possible speed. This not only minimizes the noise generated by the turbine, but also the power consumption by the compressor.
- the air compressed by the compressor is first passed through an air humidifier 6 before it is supplied to the air glasses.
- the air is passed over a water bath 7.
- the temperature of the water bath can be set via a temperature controller 8. The higher the temperature of the water bath, the more the air in the humidifier is humidified.
- a throttle valve 9 and / or a bypass valve 10 can also be provided in the hose 11 in order to control the air flow. Both valves are preferably arranged in the vicinity of the sleeper so that he can control the air flow from the bed, even if the compressor is in an adjoining room and the sleeper cannot therefore operate the turbine controller 5 from the bed.
- the connecting hose between the compressor 2 and the humidifier 6 preferably has an inside diameter of 10 to 20 mm in order to keep the pressure drop on this piece of tubing low.
- a throttle valve 9 is preferred to a bypass valve 10 for regulating the flow.
- the throttle valve does not lead to an additional air flow and on the other hand, the leak between the air goggles and the nose acts as a bypass through which the sleeper can exhale.
- a bypass must be provided through which the sleeping person can exhale.
- oxygen glasses already available on the market can be used as air glasses.
- a mask covering the nose and possibly additionally the mouth can also be used instead of the air glasses.
- Fig. 3 shows a section through a special embodiment of air glasses.
- Fig. 4 shows this embodiment in perspective.
- These air glasses comprise feed lines 25, a distributor 20 and a jacket tube 21 for each nostril of a patient.
- Each of the jacket tubes has an ergonomic cushion 24 on its outer circumference at its nasal end, which seals tightly or largely tightly with a nostril of the patient during use.
- a nozzle 18 is arranged in each casing tube, through which air under excess pressure is blown in the direction of the nostril.
- the inner cross section of the casing tube has a constriction 22 between the nozzle 18 and the nose-side end of the casing tube.
- one or both jacket tubes can have a measuring hose 26, via which the pressure in the interior of the nose can be measured.
- the interior of the casing tube 21 acts with the nozzle 18 like a jet pump.
- a small air flow enters the jacket tube through the nozzle 18 and thus pumps additional air through the open end of the jacket tube into the patient's nose.
- the nozzle 18 transform in interaction with the Casing tube 21 a small air flow that is generated by a higher pressure into a larger air flow that is under a lower pressure. This is particularly advantageous in that only part of the airflow flowing into the nose has to be transported from the compressor 2 to the nozzle 18. Due to the lower air flow, the pressure drop across the hose 11 is lower. If, on the other hand, one is ready to accept a constant pressure drop, the cross section of the tube 11 can be chosen to be smaller when using air glasses shown in FIGS. 3 and 4.
- the compressor 2 should be able to generate 100 to 1000 mbar overpressure against the ambient pressure.
- the outer shape of the ergonomic upholstery, but also the casing tube are adapted to the patient's nose shape.
- the jacket tube can be circular with a diameter of 4 to 12 mm.
- the casing tube can have an elliptical cross section, the smaller and larger radius being in the range from 2 to 6 mm.
- the jacket tube can have a length of 20 to 50 mm, in particular 30 mm.
- the hose 11 has a length of 1 to 2 m. Other dimensions result from the size of the corresponding parts of the patient's body.
- Bi-PAP devices have been developed to offer the patient greater comfort.
- the patient is supported during inhalation and exhalation by the compressor applying a higher pressure when inhaling than when exhaling.
- How to detect inhalation and exhalation is described in the German patent applications with the application numbers 101 18 968.0 and 102 00 183.9.
- the latter application is also concerned with compensating for the pressure drop in a ventilation hose 11 in order to offer the patient greater comfort.
- the relatively small pressure fluctuations in the nose and the jacket pipes produced by the patient's breathing in and out do not have a sufficient effect on the overpressure in the hose 11, which is typically 100 to 1000 mbar, these pressure fluctuations are not reasonable in the hose 11 or preferably at the outlet of the Measure turbine 3 in compressor 2.
- An additional measuring tube 26 can therefore be provided, via which the pressure inside the nose and thus in the patient's airways can be measured.
- the measuring hose 26 can lead parallel to the hose 11 to the housing of the compressor, where a pressure sensor is provided.
- the pressure sensor for measuring the intra-nasal pressure can be arranged outside the housing of the compressor 2, for example in the vicinity of the Y switch 12.
- the measuring hose 26 can only be provided on one of the two jacket tubes. In another embodiment, it can be divided into a fork, so that one end of the measuring tube is located in each casing tube. In the embodiment of the air glasses shown in FIG. 4, two feed lines 25 are provided symmetrically for the nozzles 18 in the two jacket tubes. The measuring hose 26 is fed back parallel to one of the two feed lines. In another embodiment, only one feed line 25 can be provided and the measuring tube 26 can be returned on the other side. In this embodiment, the supply line 25 parallel to the measuring tube 26 is then omitted. The measuring tube 26 and the other supply line ensure the mechanical fixing of the jacket tubes in the patient's nose.

Description
Antischnarchgerat, Verfahren zur Verringerung des Schnarchens sowie LuftbrilleAnti-snoring device, procedures for reducing snoring and air glasses
Die Erfindung bezieht sich auf ein preiswertes Gerät sowie ein Verfahren zur Verringerung des Schnarchens und eine Luftbrille.The invention relates to an inexpensive device and a method for reducing snoring and air glasses.
Obstruktive Atmungsstörungen führen zu Apnoen (Atemstillstand), durch die der Schlafende erwacht. Häufige Apnoen verhindern, dass der Schlafende in den erholsamen Tiefschlaf fällt. Menschen, die Apnoen während des Schlafens erleiden, sind deshalb tagsüber unausgeschlafen, was zu sozialen Problemen am Arbeitsplatz und im schlimmsten Fall zu tödlichen Unfällen, beispielsweise bei Berufskraftfahrern, führen kann.Obstructive breathing disorders lead to apneas (respiratory arrest), through which the sleeper awakens. Frequent apneas prevent the sleeper from falling into a restful deep sleep. People who suffer from apneas while sleeping are therefore not well rested during the day, which can lead to social problems at work and, in the worst case, fatal accidents, for example for professional drivers.
Im Stand der Technik sind Geräte zur Durchführung der CPAP (continuous positive airway pressure)-Therapie bekannt. Die CPAP-Therapie wird in Chest. Vol. 110, Seiten 1077 bis 1088, Oktober 1996 und Sleep, Vol. No. 19, Seiten 184 bis 188 näher beschrieben.Devices for carrying out CPAP (continuous positive airway pressure) therapy are known in the prior art. The CPAP therapy is in Chest. Vol. 110, pages 1077 to 1088, October 1996 and Sleep, Vol. 19, pages 184 to 188.
In der CPAP-Therapie wird einem Patienten ein konstanter positiver Druck über eine Nasenmaske zugeführt. Bei richtiger Wahl des Überdrucks gewährleistet dieser, dass die oberen Atemwege während der gesamten Nacht vollständig geöffnet bleiben und somit keine obstruktiven Atemstörungen auftreten. Der erforderliche Druck hängt unter anderem von dem Schlafstadium und der Körperposition des Schlafenden ab. Aus der DE 198 49 571 A1 ist ein Therapiegerät (AutoCPAP) bekannt, das den Beatmungsdruck automatisch einstellt und damit an das Schlafstadium und die Körpersituation anpasst.In CPAP therapy, a patient is fed a constant positive pressure through a nasal mask. If the overpressure is selected correctly, this ensures that the upper respiratory tract remains fully open throughout the night and thus no obstructive breathing disorders occur. The pressure required depends, among other things, on the stage of sleep and the body position of the sleeper. A therapy device (AutoCPAP) is known from DE 198 49 571 A1, which automatically adjusts the ventilation pressure and thus adapts to the sleep stage and the body situation.
Ferner sind aus dem Stand der Technik Sauerstoffbrillen für die Sauerstoffbehandlung bekannt. Mit der Sauerstoffbrille wird dem Patienten Luft mit einem erhöhten Sauerstoffpartialdruck (> 210 mBar) oder reiner Sauerstoff in die Nase appliziert. Eine Sauerstoffbehandlung findet zum Beispiel bei akuter oder chronischer Hypoxämie infolge Atem- oder Herz-Kreislaufstörung (Myokardinfarkt, Schock) oder bestimmten Vergiftungen, zum Beispiel durch Kohlenmonoxid, Kohlendioxid, Leuchtgas oder Rauch statt.
Schließlich ist bekannt, Rennpferde nach dem Rennen mit befeuchteter Luft zu behandeln. Dabei wird die befeuchtete Luft durch eine einer Sauerstoffbrille ähnelnden Vorrichtung, die allerdings an die Form des Pferdekopfes angepasst ist, in die Nüstern des Pferdes geleitet. Aufgrund des hohen Atemzugvolumens während eines Rennens ist die Nasenschleimhaut des Pferdes nicht in der Lage, ausreichend Feuchtigkeit abzusondern, so dass die Nasenschleimhaut austrocknet.Oxygen glasses for oxygen treatment are also known from the prior art. With the oxygen goggles, air with an increased oxygen partial pressure (> 210 mbar) or pure oxygen is applied to the patient's nose. Oxygen treatment takes place, for example, for acute or chronic hypoxemia due to respiratory or cardiovascular disorders (myocardial infarction, shock) or certain poisonings, for example through carbon monoxide, carbon dioxide, luminous gas or smoke. Finally, it is known to treat racing horses with humidified air after the race. The humidified air is conducted into the horse's nostrils through a device similar to oxygen goggles, but adapted to the shape of the horse's head. Due to the high breath volume during a race, the horse's nasal mucosa is unable to secrete sufficient moisture, so that the nasal mucosa dries out.
Aufgabe der Erfindung ist es, ein preisgünstiges und komfortables Gerät und ein Verfahren zur Verminderung des Schnarchens sowie eine Luftbrille anzugeben.The object of the invention is to provide an inexpensive and comfortable device and a method for reducing snoring as well as air glasses.
Diese Aufgabe wird durch ein Antischnarchgerat nach Anspruch 1 , ein Verfahren nach Anspruch 13 sowie eine Luftbrille nach Anspruch 15 gelöst.This object is achieved by an anti-snoring device according to claim 1, a method according to claim 13 and air glasses according to claim 15.
Vorteilhaft an einem Einsatz eines Antischnarchgeräts nach Anspruch 1 bei Personen, die zwar schnarchen, aber nicht an pathologischen Apnoen leiden, ist, dass das Antischnarchgerat, verglichen mit Geräten für die CPAP-Therapie, mit einem geringeren Fluss auskommt und somit ein kleinerer Kompressor verwendet werden kann. Darüber hinaus bietet die Luftbrille, verglichen mit den bei der CPAP- Therapie üblichen Masken, einen erhöhten Tragekomfort und einen erhöhten Sicherheitsstandard, da aufgrund des lediglich partiellen Verschlusses der Nase eine normale Atmung durch die Nase auch bei Ausfall der Turbine im Kompressor gegeben ist.An advantage of using an anti-snoring device according to claim 1 in people who snore but do not suffer from pathological apneas is that the anti-snoring device manages with a lower flow compared to devices for CPAP therapy, and thus a smaller compressor is used can. In addition, compared to the masks used in CPAP therapy, the air goggles offer increased wearing comfort and an increased standard of safety, since due to the only partial occlusion of the nose, normal breathing through the nose is ensured even if the turbine in the compressor fails.
Ein Luftbefeuchter verhindert, dass die Nasenschleimhäute des Schlafenden austrocknen und erhöht so den Komfort. Um den Partner des Schlafenden nicht durch Kompressorgeräusche anstelle der Schnarchgeräusche zu stören, ist der Kompressor akustikoptimiert. Um die Geräuschbelastung durch den Kompressor weiter zu verringern, wird das Antischnarchgerat vorzugsweise mit einem langen Schlauch ausgerüstet, so dass der Kompressor in einem Nachbarraum aufgestellt werden kann.A humidifier prevents the sleeping mucous membranes from drying out, thus increasing comfort. In order not to disturb the sleeping partner with compressor noises instead of snoring noises, the compressor is acoustically optimized. In order to further reduce the noise pollution caused by the compressor, the anti-snoring device is preferably equipped with a long hose so that the compressor can be installed in a neighboring room.
Der Luftfluss kann in vorteilhafter Weise an drei Stellen gesteuert werden: durch die Turbinendrehzahl, durch ein Drosselventil und/oder durch ein Bypass-Ventil. Vorteilhaft an der Steuerung der Turbinendrehzahl ist, dass der Kompressor bei
geringer Drehzahl und geringem Druckunterschied weniger Geräusch verursacht. Somit führt eine Steuerung des Luftflusses über die Turbinendrehzahl bei geöffnetem oder nicht vorhandenem Drosselventil und geschlossenem oder nicht vorhandenem Bypass-Ventil zur geringsten Geräuschentwicklung durch den Kompressor. Ist der Kompressor allerdings in einem Nebenraum angeordnet, so kommen als preiswerte Möglichkeiten zur Regelung des Luftflusses in der Nähe des Schlafenden lediglich ein Drosselventil oder ein Bypass-Ventil in Frage. Vorteilhaft an einem Drosselventil ist, dass es den Luftfluss durch den Kompressor und damit die Leistungsaufnahme des Kompressors reduziert. Nicht regelbare Bypass-Ventile sind aus der CPAP- Therapie bekannt. Dort sind sie notwendig, um dem Patienten das Ausatmen trotz aufgesetzter Gesichtsmaske zu ermöglichen.The air flow can advantageously be controlled at three points: by the turbine speed, by a throttle valve and / or by a bypass valve. An advantage of the control of the turbine speed is that the compressor low speed and low pressure difference causes less noise. Thus, controlling the air flow via the turbine speed with the throttle valve open or absent and the bypass valve closed or absent leads to the lowest noise generation by the compressor. However, if the compressor is arranged in an adjoining room, only a throttle valve or a bypass valve can be used as inexpensive options for regulating the air flow in the vicinity of the sleeping person. An advantage of a throttle valve is that it reduces the air flow through the compressor and thus the power consumption of the compressor. Bypass valves that cannot be regulated are known from CPAP therapy. There they are necessary to enable the patient to exhale despite the face mask being put on.
Vorteilhaft an der Verwendung eines Schlauchs mit geringem Innendurchmesser und geringem Außendurchmesser von vorzugsweise 4 bzw. 6 mm ist die häufige Verwendung und somit die preiswerte Beschaffung solcher Schläuche.An advantage of using a hose with a small inner diameter and a small outer diameter of preferably 4 or 6 mm is the frequent use and thus the inexpensive procurement of such hoses.
Vorteilhaft an der Verwendung eines Schlauchstücks mit einem größeren Innendurchmesser ist der geringere Druckabfall.The advantage of using a piece of hose with a larger inner diameter is the lower pressure drop.
Vorteilhaft an der Anordnung des Luftbefeuchters in der Nähe des Schlafenden ist die Möglichkeit, die Temperatur des Wasserbads vom Bett aus einzustellen sowie das Wasser vom Bett aus nachzufüllen. Ein Luftbefeuchter erzeugt im Gegensatz zum Kompressor keine Laufgeräusche, so dass eine Anordnung neben dem Bett unproblematisch ist.An advantage of the arrangement of the humidifier in the vicinity of the sleeping person is the possibility to set the temperature of the water bath from the bed and to refill the water from the bed. In contrast to the compressor, a humidifier does not generate any running noise, so placing it next to the bed is not a problem.
Eine Integration von Kompressor und Luftbefeuchter in einem Gerät führt zu Preisvorteilen.An integration of compressor and humidifier in one device leads to price advantages.
Vorteilhaft an einer Luftbrille, die mit der Nase des Schlafenden weitgehend dicht abschließt, ist, dass der Luftwiderstand des Bypasses nicht von der verbleibenden Öffnung zwischen Nase und Luftbrille abhängt, sondern durch die definierte Größe von Öffnungen in der Luftbrille genau eingestellt werden kann.
Vorteilhaft an einer mit vorzugsweise zwei Mantelrohren ausgestatteten Luftbrille ist, dass eine solche Luftbrille einen geringeren Luftfluss benötigt, so dass der Druckabfall in den Zuleitungsschläuchen verringert wird. Vorteilhaft an der Verwendung eines Mantelrohrs ist ferner, dass die Nasenlöcher des Patienten nicht verschlossen werden, sondern vielmehr ein definierter Querschnitt unverschlossen bleibt, so dass der Patient auch bei Ausfall des Kompressors durch die Mantelrohre ein- und ausatmen kann.An advantage of air goggles that are largely sealed with the sleeping person's nose is that the air resistance of the bypass does not depend on the remaining opening between the nose and air goggles, but can be adjusted precisely through the defined size of openings in the air goggles. An advantage of air glasses equipped with preferably two jacket tubes is that such air glasses require less air flow, so that the pressure drop in the supply hoses is reduced. Another advantage of using a jacket tube is that the patient's nostrils are not closed, but rather a defined cross section remains unlocked, so that the patient can breathe in and out through the jacket tubes even if the compressor fails.
Vorteilhaft an einer Verengung und einem Diffusor ist, dass durch eine solche Geometrie ein Strahlpumpeneffekt verstärkt wird.The advantage of a constriction and a diffuser is that a jet pump effect is enhanced by such a geometry.
Vorteilhaft an der Verwendung eines Messschlauchs 26 ist, dass hierdurch der von der Luftbrille in den Atemwegen des Patienten erzeugte Druck gemessen werden kann. Durch eine solche Messung ist es möglich, ein Ein- und Ausatmen des Patienten zu detektieren und den Luftfluss durch die Düse und damit den durch die Luftbrille in der Nase des Patienten erzeugten Druck beim Einatmen anzuheben und beim Ausatmen abzusenken.The advantage of using a measuring tube 26 is that it allows the pressure generated by the air glasses in the patient's airways to be measured. Such a measurement makes it possible to detect inhalation and exhalation of the patient and to increase the air flow through the nozzle and thus the pressure generated by the air glasses in the patient's nose during inhalation and to decrease it during exhalation.
Im Folgenden werden bevorzugte Ausführungsformen unter Bezugnahme auf die beiliegenden Zeichnungen näher erläutert. Dabei zeigen:Preferred embodiments are explained in more detail below with reference to the accompanying drawings. Show:

Das Schnarchen entsteht während des Schlafens durch stoßweise Schwingungen des schlaff herunterhängenden Gaumensegels, wenn infolge eines Spannungsverlusts der Kiefer- und Zungenmuskulatur der Unterkiefer nach unten und die Zungen nach hinten gesunken sind. Dies wird als Hindernisschnarchen
bezeichnet. Daneben kann Schnarchen auch als Folge von Gewohnheitsbildung (gemeines Schnarchen) entstehen.Snoring is caused by intermittent vibrations of the sagging soft palate during sleep, when the lower jaw and the tongues have sunk downwards as a result of a loss of tension in the jaw and tongue muscles. This is called obstacle snoring designated. In addition, snoring can also arise as a result of habit formation (common snoring).
Die Gegenstände der Erfindung sind für Personen bestimmt, die zwar schnarchen, aber nicht an pathologischen Apnoen leiden.The objects of the invention are intended for people who snore but do not suffer from pathological apneas.
Fig. 1 zeigt einen Schlafenden 14, in dessen Nase über eine Luftbrille 1 Luft appliziert wird. Diese Luft sorgt für einen leicht - also um 2 bis 20 mBar - erhöhten Luftdruck in den Atemwegen des Schlafenden. Dieser leichte Überdruck führt zu einer Erweiterung der Atemwege. Damit wird dem nach unten Sinken des Unterkiefers und dem nach hinten Sinken der Zunge entgegengewirkt.Fig. 1 shows a sleeping person 14, in whose nose 1 air is applied via air glasses. This air provides a slightly increased air pressure in the respiratory tract of the sleeping person, i.e. by 2 to 20 mbar. This slight excess pressure leads to an expansion of the airways. This counteracts the lowering of the lower jaw and the lowering of the tongue.
Die Luftbrille besteht im Wesentlichen aus zwei Schläuchen, die über die Ohren nach hinten geführt werden. Beide Schläuche werden in einer Y-Weiche 12 zu einem Schlauch zusammengeführt. Ferner ist ein verschiebbarer Ring 13 vorgesehen, um die Luftbrille an die Kopfgröße des Schlafenden anzupassen. Alternativ zu der in Fig. 1 dargestellten Trageweise können die beiden Schläuche nicht über die Ohren nach hinten, sondern um die Ohren herum und dann unterhalb des Unterkiefers zusammengeführt werden, wie es in Fig. 1 gestrichelt dargestellt ist.The air goggles essentially consist of two tubes that are led back over the ears. Both hoses are brought together in a Y-switch 12 to form a hose. Furthermore, a sliding ring 13 is provided in order to adapt the air glasses to the head size of the sleeper. As an alternative to the wearing method shown in FIG. 1, the two tubes cannot be brought together behind the ears, but around the ears and then below the lower jaw, as shown in broken lines in FIG. 1.
Bei typischen Luftbrillen weist der Schlauch 11 zwischen dem Kompressor 2 oder Luftbefeuchter 6 und der Y-Weiche 12 einen Innendurchmesser von weniger als 10 mm, beispielsweise 4 mm, sowie einen Außendurchmesser von weniger als 12 mm, bei 6 mm, auf. Die Schlauchstücke zwischen der Nase des Patienten und der Y- Weiche 12 weisen beispielsweise einen Innendurchmesser von ebenfalls weniger als 10 mm, z.B. von 3 mm und einen Außendurchmesser von weniger als 12, z.B. 5 mm auf. Aufgrund dieser geringen Querschnitte ist der Druckabfall in den Schläuchen nennenswert. Der Kompressor 2 sollte deshalb in der Lage sein, einen Überdruck von 100 bis 1000 mBar gegenüber dem Umgebungsdruck zu erzeugen. Je größer die Durchmesser der Schlauchstücke gewählt werden, umso geringer kann der vom Kompressor erzeugte Druck sein.In typical air glasses, the tube 11 between the compressor 2 or air humidifier 6 and the Y switch 12 has an inner diameter of less than 10 mm, for example 4 mm, and an outer diameter of less than 12 mm, at 6 mm. The tube pieces between the patient's nose and the Y-switch 12 have, for example, an inner diameter of also less than 10 mm, e.g. of 3 mm and an outside diameter of less than 12, e.g. 5 mm. Due to these small cross sections, the pressure drop in the hoses is noteworthy. The compressor 2 should therefore be able to generate an overpressure of 100 to 1000 mbar compared to the ambient pressure. The larger the diameter of the hose pieces are chosen, the lower the pressure generated by the compressor can be.
Die Auslässe der Luftbrille können - wie bei Sauerstoffbrillen üblich - kleiner als die Nasenöffnungen des Schlafenden sein. In diesem Fall kann der Schlafende durch
den Spalt zwischen den Auslässen und der Nasenbrille ausatmen. Dieser Spalt bildet sozusagen einen nicht regelbaren Bypass.The outlets of the air goggles can - as is usual with oxygen goggles - be smaller than the nostrils of the sleeping person. In this case, the sleeper can go through Exhale the gap between the outlets and the nasal cannula. This gap forms a non-controllable bypass, so to speak.
Andererseits können die Auslässe der Luftbrille an die Form der Nasenlöcher angepasst sein, so dass sie weitgehend dicht mit den Nasenlöchern abschließen. In diesem Fall können in der Luftbrille Öffnungen 15 zum Ausatmen vorgesehen sein, die durch Schiebe- oder Drehelemente zu einem regelbaren Ventil ergänzt werden können.On the other hand, the outlets of the air glasses can be adapted to the shape of the nostrils, so that they are largely sealed with the nostrils. In this case, openings 15 for breathing out can be provided in the air goggles, which can be supplemented by sliding or rotating elements to form a controllable valve.
Die komprimierte Luft wird durch einen Kompressor 2 erzeugt. Um die Schnarchgeräusche nicht durch andere unangenehme Geräusche zu ersetzen, ist der Kompressor 2 akustikoptimiert. Daneben verfügt er über eine Schalldämmung 4. Damit die Turbine 3 im Kompressor mit möglichst geringer Drehzahl läuft, ist ein Turbinenregler 5 vorgesehen. Dabei wird nicht nur die Geräuscherzeugung durch die Turbine minimiert, sondern auch die Stromaufnahme durch den Kompressor.The compressed air is generated by a compressor 2. In order not to replace the snoring noises with other unpleasant noises, the compressor 2 is acoustically optimized. In addition, it has sound insulation 4. A turbine controller 5 is provided so that the turbine 3 runs in the compressor at the lowest possible speed. This not only minimizes the noise generated by the turbine, but also the power consumption by the compressor.
In einer bevorzugten Ausführungsform der Erfindung wird die durch den Kompressor komprimierte Luft zunächst durch einen Luftbefeuchter 6 geleitet, bevor sie der Luftbrille zugeführt wird. Im Luftbefeuchter wird die Luft über ein Wasserbad 7 geleitet. Die Temperatur des Wasserbads kann über einen Temperaturregler 8 eingestellt werden. Je höher die Temperatur des Wasserbads ist, desto stärker wird die Luft im Luftbefeuchter befeuchtet.In a preferred embodiment of the invention, the air compressed by the compressor is first passed through an air humidifier 6 before it is supplied to the air glasses. In the humidifier, the air is passed over a water bath 7. The temperature of the water bath can be set via a temperature controller 8. The higher the temperature of the water bath, the more the air in the humidifier is humidified.
Zusätzlich oder alternativ zum Turbinenregler 5 kann im Schlauch 11 noch ein Drosselventil 9 und/oder ein Bypass-Ventil 10 vorgesehen sein, um den Luftfluss zu steuern. Beide Ventile sind vorzugsweise in der Nähe des Schlafenden angeordnet, so dass er den Luftfluss vom Bett aus steuern kann, auch wenn der Kompressor in einem Nebenraum steht und der Schlafende deshalb den Turbinenregler 5 vom Bett aus nicht bedienen kann.In addition or as an alternative to the turbine controller 5, a throttle valve 9 and / or a bypass valve 10 can also be provided in the hose 11 in order to control the air flow. Both valves are preferably arranged in the vicinity of the sleeper so that he can control the air flow from the bed, even if the compressor is in an adjoining room and the sleeper cannot therefore operate the turbine controller 5 from the bed.
Ist der Kompressor 2 in einem Nebenraum und der Luftbefeuchter 6 neben dem Bett des Schlafenden angeordnet, so hat der Verbindungsschlauch zwischen Kompressor 2 und Luftbefeuchter 6 vorzugsweise einen Innendurchmesser von 10 bis 20 mm, um den Druckabfall an diesem Schlauchstück gering zu halten.
Wenn die Luftbrille nicht weitgehend dicht mit den Nasenlöchern des Schlafenden abschließt, wird zur Regelung des Flusses einem Drosselventil 9 der Vorzug vor einem Bypass-Ventil 10 gegeben. Einerseits führt das Drosselventil nicht zu einem zusätzlichen Luftfluss und andererseits wirkt die Undichtigkeit zwischen der Luftbrille und der Nase wie ein Bypass, durch den der Schlafende ausatmen kann. Schließt andererseits die Luftbrille mit den Nasenlöchern des Schlafenden weitgehend dicht ab, so muss ein Bypass vorgesehen werden, durch den der Schlafende ausatmen kann.If the compressor 2 is arranged in an adjoining room and the humidifier 6 next to the bed of the sleeper, the connecting hose between the compressor 2 and the humidifier 6 preferably has an inside diameter of 10 to 20 mm in order to keep the pressure drop on this piece of tubing low. If the air goggles are not largely sealed with the nostrils of the sleeping person, a throttle valve 9 is preferred to a bypass valve 10 for regulating the flow. On the one hand, the throttle valve does not lead to an additional air flow and on the other hand, the leak between the air goggles and the nose acts as a bypass through which the sleeper can exhale. On the other hand, if the air goggles are largely sealed with the nostrils of the sleeping person, a bypass must be provided through which the sleeping person can exhale.
In einer weiteren bevorzugten Ausführungsform können als Luftbrillen bereits am Markt verfügbare Sauerstoffbrillen verwendet werden. In einer weiteren bevorzugten Ausführungsform kann anstelle der Luftbrille auch eine die Nase und evtl. zusätzlich den Mund abdeckende Maske verwendet werden.In a further preferred embodiment, oxygen glasses already available on the market can be used as air glasses. In a further preferred embodiment, a mask covering the nose and possibly additionally the mouth can also be used instead of the air glasses.
Fig. 3 zeigt einen Schnitt durch eine besondere Ausführungsform einer Luftbrille. Fig. 4 zeigt diese Ausführungsform perspektivisch. Diese Luftbrille umfasst Zuleitungen 25, einen Verteiler 20 sowie ein Mantelrohr 21 für jedes Nasenloch eines Patienten. Jedes der Mantelrohre weist an seinem nasenseitigen Ende an seinem Außenumfang ein ergonomisches Polster 24 auf, das während der Anwendung dicht oder weitgehend dicht mit einem Nasenloch des Patienten abschließt. In jedem Mantelrohr ist eine Düse 18 angeordnet, durch die unter einem Überdruck stehende Luft in Richtung Nasenloch geblasen wird. Der innere Querschnitt des Mantelrohrs weist eine Verengung 22 zwischen der Düse 18 und dem nasenseitigen Ende des Mantelrohrs auf. Der Bereich zwischen der Verengung 22 und dem nasenseitigen Ende des Mantelrohrs, in dem sich der lichte Querschnitt des Mantelrohrs zum nasenseitigen Ende des Mantelrohrs hin aufweitet, wird als Diffusor 23 bezeichnet. Daneben kann eines oder beide Mantelrohre einen Messschlauch 26 aufweisen, über den der Druck im Naseninneren gemessen werden kann.Fig. 3 shows a section through a special embodiment of air glasses. Fig. 4 shows this embodiment in perspective. These air glasses comprise feed lines 25, a distributor 20 and a jacket tube 21 for each nostril of a patient. Each of the jacket tubes has an ergonomic cushion 24 on its outer circumference at its nasal end, which seals tightly or largely tightly with a nostril of the patient during use. A nozzle 18 is arranged in each casing tube, through which air under excess pressure is blown in the direction of the nostril. The inner cross section of the casing tube has a constriction 22 between the nozzle 18 and the nose-side end of the casing tube. The area between the constriction 22 and the nose-side end of the jacket tube, in which the clear cross section of the jacket tube widens towards the nose-side end of the jacket tube, is referred to as diffuser 23. In addition, one or both jacket tubes can have a measuring hose 26, via which the pressure in the interior of the nose can be measured.
Das Innere des Mantelrohrs 21 wirkt mit der Düse 18 wie eine Strahlpumpe (engl. jet pump). Durch die Düse 18 tritt ein kleiner Luftstrom in das Mantelrohr und pumpt so zusätzliche Luft durch das offene Ende des Mantelrohrs in die Nase des Patienten. Anders ausgedrückt, transformieren die Düse 18 im Zusammenspiel mit dem
Mantelrohr 21 einen kleinen Luftstrom, der durch einen höheren Überdruck erzeugt wird in einen größeren Luftstrom, der unter einem geringeren Überdruck steht. Vorteilhaft hieran ist insbesondere, dass nur ein Teil des in die Nase strömenden Luftstroms vom Kompressor 2 zur Düse 18 transportiert werden muss. Aufgrund des geringeren Luftstroms ist der Druckabfall am Schlauch 11 geringer. Ist man andererseits bereit, einen konstanten Druckabfall in Kauf zu nehmen, so kann der Querschnitt des Schlauchs 11 bei Verwendung einer in Fig. 3 und 4 gezeigten Luftbrille kleiner gewählt werden.The interior of the casing tube 21 acts with the nozzle 18 like a jet pump. A small air flow enters the jacket tube through the nozzle 18 and thus pumps additional air through the open end of the jacket tube into the patient's nose. In other words, the nozzle 18 transform in interaction with the Casing tube 21 a small air flow that is generated by a higher pressure into a larger air flow that is under a lower pressure. This is particularly advantageous in that only part of the airflow flowing into the nose has to be transported from the compressor 2 to the nozzle 18. Due to the lower air flow, the pressure drop across the hose 11 is lower. If, on the other hand, one is ready to accept a constant pressure drop, the cross section of the tube 11 can be chosen to be smaller when using air glasses shown in FIGS. 3 and 4.
Wie oben erwähnt, sollte der Kompressor 2 in der Lage sein, 100 bis 1000 mBar Überdruck gegenüber dem Umgebungsdruck zu erzeugen. Insbesondere die Außenform der ergonomischen Polster, aber auch das Mantelrohr werden an die Nasenform des Patienten angepasst. Das Mantelrohr kann kreisförmig mit einem Durchmesser von 4 bis 12 mm ausgeführt sein. In anderen Ausführungsformen kann das Mantelrohr einen elliptischen Querschnitt aufweisen, wobei der kleinere und größere Radius im Bereich von 2 bis 6 mm liegen können. Das Mantelrohr kann eine Länge von 20 bis 50 mm, insbesondere von 30 mm aufweisen. Der Schlauch 11 weist eine Länge von 1 bis 2 m auf. Andere Abmessungen ergeben sich aus der Größe der entsprechenden Körperteile des Patienten.As mentioned above, the compressor 2 should be able to generate 100 to 1000 mbar overpressure against the ambient pressure. In particular, the outer shape of the ergonomic upholstery, but also the casing tube, are adapted to the patient's nose shape. The jacket tube can be circular with a diameter of 4 to 12 mm. In other embodiments, the casing tube can have an elliptical cross section, the smaller and larger radius being in the range from 2 to 6 mm. The jacket tube can have a length of 20 to 50 mm, in particular 30 mm. The hose 11 has a length of 1 to 2 m. Other dimensions result from the size of the corresponding parts of the patient's body.
Um dem Patienten einen höheren Komfort zu bieten, wurden sog. Bi-PAP-Geräte entwickelt. Bei diesen Geräten wird der Patient beim Ein- und Ausatmen dadurch unterstützt, dass der Kompressor beim Einatmen einen höheren Druck appliziert als beim Ausatmen. Wie man Ein- und Ausatmen detektiert, ist in den deutschen Patentanmeldungen mit den Anmeldenummern 101 18 968.0 sowie 102 00 183.9 beschrieben. Die letztere Anmeldung beschäftigt sich ferner damit, den Druckabfall in einem Beatmungsschlauch 11 zu kompensieren, um dem Patienten einen höheren Komfort zu bieten.So-called Bi-PAP devices have been developed to offer the patient greater comfort. With these devices, the patient is supported during inhalation and exhalation by the compressor applying a higher pressure when inhaling than when exhaling. How to detect inhalation and exhalation is described in the German patent applications with the application numbers 101 18 968.0 and 102 00 183.9. The latter application is also concerned with compensating for the pressure drop in a ventilation hose 11 in order to offer the patient greater comfort.
Da nach dem derzeitigen Kenntnisstand die relativ geringen, durch das Ein- und Ausatmen des Patienten erzeugten Druckschwankungen in der Nase und den Mantelrohren keine ausreichende Rückwirkung auf den mit typischerweise 100 bis 1000 mBar hohen Überdruck im Schlauch 11 haben, sind diese Druckschwankungen nicht mit vernünftigem Aufwand im Schlauch 11 oder vorzugsweise am Auslass der
Turbine 3 im Kompressor 2 zu messen. Deshalb kann ein zusätzliche Messschlauch 26 vorgesehen werden, über den der Druck im Inneren der Nase und damit in den Atemwegen des Patienten gemessen werden kann. Der Messschlauch 26 kann parallel zum Schlauch 11 zum Gehäuse des Kompressors führen, wo ein Drucksensor vorgesehen ist. In anderen Ausführungsformen kann der Drucksensor zur Messung des Naseninnendrucks außerhalb des Gehäuses des Kompressor 2, beispielsweise in der Nähe der Y-Weiche 12, angeordnet sein. Der Messschlauch 26 kann nur an einem der beiden Mantelrohre vorgesehen sein. In einer anderen Ausführungsform kann er gabelförmig aufgeteilt werden, so dass sich in jedem Mantelrohr ein Ende des Messschlauchs befindet. In der in Fig. 4 dargestellten Ausführungsform der Luftbrille sind symmetrisch zwei Zuleitungen 25 für die Düsen 18 in den beiden Mantelrohren vorgesehen. Der Messschlauch 26 wird parallel zu einer der beiden Zuleitungen zurückgeführt. In einer anderen Ausführungsform kann lediglich eine Zuleitung 25 vorgesehen sein und der Messschlauch 26 auf der anderen Seite zurückgeführt werden. Bei dieser Ausführungsform entfällt dann die Zuleitung 25 parallel zum Messschlauch 26. Der Messschlauch 26 und die andere Zuleitung sorgen für die mechanische Fixierung der Mantelrohre in der Nase des Patienten.Since, according to the current state of knowledge, the relatively small pressure fluctuations in the nose and the jacket pipes produced by the patient's breathing in and out do not have a sufficient effect on the overpressure in the hose 11, which is typically 100 to 1000 mbar, these pressure fluctuations are not reasonable in the hose 11 or preferably at the outlet of the Measure turbine 3 in compressor 2. An additional measuring tube 26 can therefore be provided, via which the pressure inside the nose and thus in the patient's airways can be measured. The measuring hose 26 can lead parallel to the hose 11 to the housing of the compressor, where a pressure sensor is provided. In other embodiments, the pressure sensor for measuring the intra-nasal pressure can be arranged outside the housing of the compressor 2, for example in the vicinity of the Y switch 12. The measuring hose 26 can only be provided on one of the two jacket tubes. In another embodiment, it can be divided into a fork, so that one end of the measuring tube is located in each casing tube. In the embodiment of the air glasses shown in FIG. 4, two feed lines 25 are provided symmetrically for the nozzles 18 in the two jacket tubes. The measuring hose 26 is fed back parallel to one of the two feed lines. In another embodiment, only one feed line 25 can be provided and the measuring tube 26 can be returned on the other side. In this embodiment, the supply line 25 parallel to the measuring tube 26 is then omitted. The measuring tube 26 and the other supply line ensure the mechanical fixing of the jacket tubes in the patient's nose.
