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.
