Abstract
Description
Die Erfindung betrifft eine Inhalationstherapievorrichtung mit einem Aerosolmembrangenerator und einer Mischkammer sowie einem Einatemventil.The invention relates to an inhalation therapy device with an aerosol membrane generator and a mixing chamber as well as a Inhalation valve.
Mit Inhalationstherapievorrichtungen dieser Art können medikamenthaltige Flüssigkeiten, flüssige Medikamente oder andere therapeutisch einsetzbare Flüssigkeiten, beispielsweise Salzlösungen, vernebelt werden, um dem Patienten ein Aerosol für die Inhalation darzubieten.With inhalation therapy devices of this kind can medicated liquids, liquid Drugs or other therapeutically usable liquids, for example, saline solutions to provide the patient with an aerosol for inhalation.
Wenn bei dem bekannten Therapievernebler der Patient in die Vorrichtung hinein ausatmet, gelangt zwar ein großer Teil der Atemluft über ein in einem Mundstück der Vorrichtung vorgesehenes Ausatemventil unmittelbar in Umgebung, jedoch sind auch der Aerosolmembrangenerator und der Bereich des Flüssigkeitsvorratsbehälters einem Teil der Atemluft ausgesetzt. Es kommt auf diese Weise zu unerwünschten Verunreinigungen des Aerosolgenerators.If in the known nebulizer therapy A large part of the patient exhales into the device the air we breathe one in a mouthpiece the exhalation valve provided in the device directly in the vicinity, however, the aerosol membrane generator and the area of the Liquid storage container one Part of the breathing air exposed. This leads to undesirable ones Contamination of the aerosol generator.
Das von der Erfindung zu lösende Problem besteht vor dem Hintergrund dieses Standes der Technik darin, eine Inhalationstherapievorrichtung anzugeben, bei der das Einatemventil derart gestaltet ist, dass das Risiko einer Verunreinigung des Aerosolmembrangenerators durch die Atemluft des Patienten während der Ausatemphasen verringert ist.The problem to be solved by the invention is against the background of this prior art in specifying an inhalation therapy device, in which the inhalation valve is designed so that the risk contamination of the aerosol membrane generator by the breathing air of the patient during the phases of exhalation is reduced.
Dieses Problem wird gelöst durch eine Inhalationstherapievorrichtung mit einem Aerosolmembrangenerator, mit einem Flüssigkeitsvorratsbehälter, in den eine medikamenthaltige Flüssigkeit einfüllbar ist, mit einer Membran, die auf einer Seite mit dem Flüssigkeitsbehälter derart in Verbindung steht, dass eine in den Flüssigkeitsvorratsbehälter eingefüllte Flüssigkeit in Berührung mit einer Seite der Membran gelangt, und mit einem Schwingungsgenerator, durch den die Membran in Schwingungen versetzbar ist, so dass eine in den Flüssigkeitsvorratsbehälter eingefüllte Flüssigkeit durch Öffnungen der Membran hindurch auf der anderen Seite der Membran zu einem Aerosol zerstäubt wird, einer Mischkammer, in die hinein der Aerosolmembrangenerator das Aerosol erzeugt, und einem Einatemventil, das in Einatemphasen den Zustrom von Umgebungsluft in die Mischkammer zulässt und in Ausatemphasen das Austreten des Aerosols aus der Mischkammer verhindert, das einen Wandabschnitt der Mischkammer bildet, das einen trichterartig zulaufenden Bereich aufweist, dessen zulaufendes Ende eine Ventilöffnung umfasst und sich zum Aerosolmembrangenerator erstreckt, so dass ein die Ventilöffnung umschließender Rand in der Ruhelage des Einatemventils auf einer Oberfläche des Aerosolmembrangenerators die Membran umschließend angeordnet ist.This problem is solved by an inhalation therapy device with an aerosol membrane generator, with a liquid reservoir, in a drug-containing liquid is fillable, with a membrane that is on one side with the liquid container is related to a liquid filled in the liquid reservoir in touch with one side of the membrane, and with a vibration generator which the membrane can be set in vibration, so that an in liquid filled in the liquid reservoir through openings through the membrane on the other side of the membrane into one Aerosol atomized is a mixing chamber into which the aerosol membrane generator the aerosol generates, and an inhalation valve that is in inhalation phases allows the inflow of ambient air into the mixing chamber and in exhalation phases the aerosol escapes from the mixing chamber prevents forming a wall section of the mixing chamber, the has a funnel-like area, the tapered area End of a valve opening includes and extends to the aerosol membrane generator so that a the valve opening enclosing Edge in the rest position of the inhalation valve on a surface of the Aerosol membrane generator surrounds the membrane.
Die trichterartige Gestaltung des Ventils gemäß der Erfindung bewirkt, dass einerseits ein formstabiles und flexibles Ventilelement die Funktion als Einatemventil bereitstellt und das andererseits eine günstige Strömungsführung der Zuluft erzielt wird, da die Ventilöffnung die Membran und damit die Zuluft das von ihr erzeugte Aerosol umgibt. Durch die einem Trichter ähnelnde Gestaltung wird somit erreicht, dass in Einatemphasen sich das Aerosol in geringerem Umfang in der Mischkammer niederschlägt.The funnel-like design of the Valve according to the invention causes on the one hand a dimensionally stable and flexible valve element provides the function as an inhalation valve and on the other hand a cheap one Flow guidance of the Supply air is achieved because the valve opening the membrane and thus the supply air surrounds the aerosol it produces. Through the one Funnel-like Design is thus achieved in that the aerosol in inhalation phases to a lesser extent in the mixing chamber.
Indem das Einatemventil als Wandabschnitt ausgebildet ist, legt es die Dimensionen der Mischkammer mit fest, wodurch unmittelbar eine Minimierung des mit Aerosol in Kontakt kommenden Raumes erzielt wird. Mit anderen Worten, durch die erfindungsgemäße trichterartige Gestaltung in Form eines Wandabschnitts wird ein Bereich für das Einatemventil vermieden, der zusätzlich zu der Mischkammer vorzusehen ist und dann auch mit Aerosol in Berührung kommt. Die Reinigung des Therapiegerät ist entsprechend einfacher.By designing the inhalation valve as a wall section , it also defines the dimensions of the mixing chamber, which makes it immediately minimizes the space in contact with aerosol becomes. In other words, the funnel-like according to the invention Design in the form of a wall section becomes an area for the inhalation valve avoided that in addition to the mixing chamber and then comes into contact with aerosol. The cleaning of the therapy device is correspondingly easier.
In einer vorteilhaften Ausgestaltung ist der trichterartige Bereich des Einatemventils abgerundet, konisch-eben, stufig oder meanderförmig ausgestaltet ist.In an advantageous embodiment the funnel-like area of the inhalation valve is rounded, conical, stepped or meandering is designed.
Zur Erhöhung der Formstabilität und zum Schutz des Ventils gegen Beschädigungen weist vorteilhafterweise der Rand der Ventilöffnung umlaufend eine Verdickung oder einen Wulst auf.To increase shape stability and protection the valve against damage the edge of the valve opening advantageously has a thickening all around or a bead.
Damit das Einatemventil einfacher handhabbar und gegen Beschädigungen geschützt wird, weist das Einatemventil neben dem Ventilelement einen Randabschnitt auf. Der Randbereich ist vorzugsweise für die Halterung des Einatemventils, insbesondere für das Einklemmen zwischen dem Aerosolgenerator und der Mischkammer ausgestaltet.To make the inhalation valve easier manageable and against damage protected the inhalation valve has an edge section next to the valve element on. The edge area is preferably for holding the inhalation valve, especially for pinching between the aerosol generator and the mixing chamber designed.
Um einerseits ausreichend formstabil und andererseits gleichzeitig ausreichend flexibel zu sein, ist das Einatemventil vorzugsweise aus einem elastischen Material hergestellt.On the one hand, it is sufficiently dimensionally stable and at the same time being flexible enough the inhalation valve is preferably made of an elastic material.
