Description
Die Erfindung betrifft eine Blasenscheibe und einen diese Blasenscheibe aufweisenden Inhalator.The Invention relates to a bladder disc and a bladder disc having inhaler.
Verschiedene Medikamente können in Form einer trockenen Pulvermischung durch den Mund oder die Nase direkt in die Lunge inhaliert werden. Inhalieren ermöglicht es dem Medikament, das Verdauungssystem zu umgehen, und kann die Notwendigkeit stärker intervenierender Medikament-Verabreichungs-Techniken, wie beispielsweise subkutaner Injektionen und so weiter, zu eliminieren. Durch direktes Inhalieren kann es in einigen Fällen ermöglicht werden, geringere Dosen eines Medikaments zu verwenden, um die gleichen Resultate zu erreichen, als wenn das gleiche Medikament oral verabreicht worden wäre. In anderen Fällen kann Inhalieren unerwünschte Nebenwirkungen vermeiden helfen.Various Medication can in the form of a dry powder mixture through the mouth or nose be inhaled directly into the lungs. Inhalation makes it possible the drug to bypass the digestive system, and may need stronger intervening drug delivery techniques, such as subcutaneous injections and so on. Inhaling directly may, in some cases, allow lower doses using a drug to achieve the same results as if the same drug had been given orally. In other make can inhale unwanted Help avoid side effects.
Verschiedene
Pulver-Inhalatoren wurden verwendet, um direktes Inhalieren eines
pulverförmigen
Medikaments zu ermöglichen.
Repräsentative Literatur
des allgemeinen Bereiches kann in WO 92/04069,
Dementsprechend ist ein Ziel der Erfindung eine verbesserte Blasenscheibe zum Verwenden in einem Inhalator bereitzustellen.Accordingly is an object of the invention to use an improved bladder disc to provide in an inhaler.
Das obengenannte Ziel wird durch eine Blasenscheibe mit den Merkmalen gemäß Anspruch 1 erreicht. Hierbei sei angemerkt, dass eine Blasenscheibe mit den Merkmalen des Oberbegriffes von Anspruch 1 aus dem US-Patent 4778054 bekannt ist.The The above goal is achieved through a bladder disc with the characteristics according to claim 1 reached. It should be noted here that a bladder disc with the Features of the preamble of claim 1 from U.S. Patent 4,777,054 is known.
Die Blasenscheibe der vorliegenden Erfindung weist vorzugsweise eine Mehrzahl von untereinander mit Zwischenräumen versehenen Blasen auf. Die Blasenschalen sind vorzugsweise auf eine darunterliegende Metallfolien-Scherschicht dicht aufgebracht. In einer bevorzugten Ausführungsform ist die Scherschicht mit einer Trägerscheibe verbunden ("bonded"). Vorzugsweise sind unterhalb jeder Blasenschale Scherlaschen angeordnet und mit dieser verbunden ("bonded"), wobei die Laschen von der Trägerscheibe durch einen Spalt getrennt sind.The The bladder disk of the present invention preferably has one A plurality of interspaced bubbles. The Bubble shells are preferably sealed to an underlying metal foil shear layer applied. In a preferred embodiment, the shear layer is with a carrier disc bonded. Are preferred Shear tabs are arranged below each bladder shell and connected to it ("bonded"), the tabs from the carrier disc are separated by a gap.
Weitere Ziele und Merkmale der vorliegenden Erfindung werden durch folgende detaillierte Beschreibung in Verbindung mit den begleitenden Zeichnungen offensichtlich werden. Die Zeichnungen sind allerdings nur zu Zwecken der Erläuterung angegeben, und sind nicht dazu gedacht, als Begrenzung des Schutzumfanges der Erfindung zu gelten.Further Objects and features of the present invention will be as follows detailed description in conjunction with the accompanying drawings become obvious. However, the drawings are for purposes only the explanation specified, and are not intended to limit the scope of protection to apply the invention.
In den Zeichnungen, in denen gleiche Bezugszeichen innerhalb der verschiedenen Ansichten gleiche Elemente bezeichnen, zeigt:In the drawings, in which the same reference numerals within the different Identifying views with the same elements shows:
