Definitions

  • the invention relates to a control device of the type mentioned in the preamble of patent claim 5 as well as anti-snoring devices of the type mentioned in the preambles of claims 1, 8 and 9.
  • Inventive objects can be used, for example, for the therapy of chronic obstructive pulmonary disease (COPD) be used.
  • COPD chronic obstructive pulmonary disease
  • CPAP continuous positive airway pressure
  • CPAP therapy In CPAP therapy, a patient is given a constant positive pressure via a nasal mask. If the overpressure is properly selected, it will ensure that the upper airways remain fully open throughout the night, preventing obstructive respiratory disorders. The required pressure depends, among other things, on the sleeping stage and the body position of the sleeping person.
  • WO 02/083221 A2 (HEWO5) discloses a therapy device (AutoCPAP) which automatically adjusts the respiratory pressure and thus adapts it to the sleep stage and the body situation in order to limit the overpressure that is perceived as unpleasant to the required level.
  • WO 02/083221 A2 is incorporated by reference into this application.
  • Some CPAP devices also compensate for the pressure drop across the tube between CPAP
  • BiPAP devices and multilevel devices have also been developed. These devices have the property of helping the patient to breathe by lowering the pressure during exhalation and increasing the pressure again when inhaling. These devices work with at least two print levels.
  • Such a device is known for example from DE 691 32 030 T2.
  • the pressure is raised by a valve during inhalation and lowered during exhalation.
  • the valve is controlled to maintain constant pressure during inhalation and exhalation. If the valve position changes only slowly during an inhalation process, this is interpreted as the end of the inhalation process.
  • Inaudible vibrations or pressure changes can be evaluated to determine if the patient's breathing is regular, irregular or apneic.
  • the duration of inhalation and exhalation and the flow rates can be determined. This information can be stored in memory.
  • an admittance from respiratory flow divided by pressure can be calculated. The time course of the admittance can be compared with stored admittance schemes. The number of the most appropriate admittance scheme may be used as a "pointer" to a table containing the action to be taken, such as an increase in pressure.
  • PAP devices for performing PAP therapy.
  • WO 02/26283 A2 discloses a method and a device for generating a variable overpressure in the airways in order, among other things, to treat sleep apnea.
  • a pressure generating system includes a gas flow generator and a pressure controller, such as a valve.
  • the gas flow generator may be a blower, as used in conventional CPAP devices, the respiratory gas from a suitable source such as a pressurized tank with oxygen or air and / or the surrounding atmosphere.
  • a suitable source such as a pressurized tank with oxygen or air and / or the surrounding atmosphere.
  • a flow sensor is provided to measure the flow of the breathing gas to the patient. In particular, the peak flow during the patient's breathing cycles is measured to detect Cheyne-Stokes respiration (CSR).
  • CSR Cheyne-Stokes respiration
  • JP2002-143307 A discloses an oxygen ventilator.
  • WO 88/10108 A1 discloses a device for monitoring respiration during sleep and for controlling CPAP therapy.
  • a microphone is used to record snoring and breathing sounds. If the evaluation of the microphone signal indicates snoring, the CPAP pressure will be increased.
  • oxygen glasses for the oxygen treatment are known from the prior art. With the oxygen goggles air is applied to the patient with an increased oxygen partial pressure (> 210 mbar) or pure oxygen in the nose.
  • oxygen treatment occurs in acute or chronic hypoxemia due to respiratory or cardiovascular disorder (myocardial infarction, shock) or certain poisoning, for example, carbon monoxide, carbon dioxide, fluorescent gas or smoke.
  • WO 02/062413 A2 discloses the use of oxygen spectacles in an anti-snoring device. Oxygen goggles are referred to in this context as air goggles. From WO 02/062413 A2 air goggles with integrated jet pumps are also known, as shown in FIGS. 4 and 5.
  • Preferred embodiments of the invention are subject of the dependent claims.
  • An advantage of a control device which ensures that an application device applies air, especially during inspiration, is that the respiratory activity of the patient is supported. The patient therefore has less the feeling of having to exhale against resistance.
  • the mean air flow decreases, because during the expiratory phases no or only a few air is applied. This increases the service life of a gas cartridge filling, if a gas cartridge is used as a pressure generator.
  • tracheostomy tube applies the air directly to the respiratory tract. This reduces the required air flow to the application through goggles to maintain a constant overpressure in the airways to prevent flow restriction by restricting the airways during inhalation. The narrowing of the airways can cause snoring.
  • An advantage of the use of a pair of goggles as an application device is their low price.
  • the wearing of a pair of goggles is perceived by many patients to be more comfortable than wearing a face mask or nasal mask.
  • an active agent may be added to the water bath of the humidifier. No additional equipment is required for this.
  • the pressure fluctuations due to the respiratory activity of the patient are relatively low compared to the pressure drop across the tube between the inlet and outlet of the goggles or tracheostomy tube.
  • the pressure fluctuations due to the respiratory activity are damped by the hose, so that they are less strong at the inlet than at the outlet. There are therefore pressure sensors with a high dynamic range required.
  • the tube may be caused by the air flow vortex, which are superimposed on the attributable to the breathing activity pressure fluctuations and distort them.
  • the tracheostomy tube for air supply and the nasal mask for pressure measurement or vice versa may be used, with one outlet for air delivery and the other for pressure measurement.
  • a tracheostomy tube with two outlets, one for pressure measurement, the other for air supply can be used.
  • gas cartridges allow a cost reduction, since the anti-snoring device no longer has to be equipped with a turbine, which is also referred to as a fan, compressor or blower.
  • the gas in the gas cartridge can be added to the factory with active ingredients.
  • An additional device, which is required, for example, for displacing the air delivered by a fan with active substance, can advantageously be dispensed with.
  • a jet pump is an inexpensive component that significantly extends the useful life of a gas cartridge filling in an advantageous manner.
  • FIG. 1 shows an inventive control device for an anti-snoring device
  • FIG. 2 shows a sleeper with air goggles and tracheal cannula
  • FIG. 3 shows a further embodiment of an anti-snoring device
  • FIG. 4 shows a section through a pair of air-rimmed goggles; such as Figure 5 is a equipped with two jacketed airbags.
  • FIG. 1 shows an inventive control device 1 for an anti-snoring device.
  • the control unit 1 may comprise a glass bottle 2, a valve 3, a microprocessor 4, a jet pump 5, a humidifier 6, a flow sensor 11, a first pressure sensor 12, a second pressure sensor 13 and a microphone 16.
  • the gas cylinder 2 may contain compressed air.
  • the gas bottle 2 may contain an active substance 17, which is shown in FIG. 1 by small dots. Aerosols, fragrances such as a seawater additive or medicine can be added to the air as an active ingredient.
  • Gas bottles can be disposable gas bottles or refillable gas cylinders.
  • the gas cylinder 2 is connected to the valve 3 via an inlet port 19.
  • the inlet port 19 may be connected to a clinical compressed air supply or other compressed air network instead of the gas cylinder 2.
  • the valve 3 is controlled by the microprocessor 4.
  • the microprocessor 4 further opens the valve 3 the more the pressure of the gas cylinder 2 decreases.
  • the microprocessor 4 closes the valve 3 during the expiration phases. During the inspiration phases, the valve is increasingly opened in accordance with the time drop of the pressure in the gas cylinder 2.
  • the microprocessor 4 can open the valve 3 all the more, the stronger the sleeper's snoring.
  • the outlet of the valve 3 is connected to a first inlet of the jet pump 5.
  • the jet pump 5 sucks ambient air.
  • the jet pump converts high pressure and low flow at the first inlet into low pressure and high flow at the outlet.
