Abstract

The invention relates to a tracheal cannula comprising a displaceable shield. The aim of the invention is to provide a tracheal cannula comprising a displaceable shield which can pivot and rotate freely in all spatial directions and also has high mechanical stability during high loads. Said aim is achieved by virtue of the fact that the tracheal cannula consists of a pipe or tube-shaped cannula (1) for passing the cannula through the throat or trachea incision into the trachea of a patient, wherein an, optionally, tube-shaped internal cannula can be guided and controlled by means of the cannula (1). Said tracheal cannula also consists of a cannula shield (2) which is arranged in a displaceable manner on the cannula (1) and which engages through the cannula (1) in order to arrange on the throat which defines the position of the cannula (1) and/or the end of the cannula (1) in the trachea of the patient. The cannula (1) can be rotated about a spatial axis (X) in relation to the cannula shield (2) and is pivotably mounted in any particular manner about two spatial axes (Y, Z).

Beschreibungdescription
Die Erfindung betrifft eine Trachealkanüle mit beweglichen Schild.The invention relates to a tracheal cannula with movable shield.
Die Schrift DE 197 39 103 Al offenbart eine Tracheotomiekanüle, bestehend aus einem röhr- oder schlauchförmigen Element für die Hindurchführung durch einen Hals- und Luftröhrenschnitt in die Luftröhre eines Patienten, wenn dessen obere Atemwege blockiert sind, um den Patienten durch die Kanüle mit Atemluft zu versorgen, und mit einem an der Kanüle angebrachten Schild, durch dessen Anlage am Hals des Patienten die Position der Kanüle bzw. des Endes der Kanüle in der Luftröhre des Patienten definiert wird. Um eine Tracheotomiekanüle mit den eingangs genannten Merkmalen zu schaffen, welche in einfacher Weise an die bei einem Patienten vorliegenden, anatomischen Gegebenheiten anpaßbar ist und keinen größeren Aufwand hinsichtlich der Bevorratung und Anpassung von Tracheotomiekanülen verursacht, wird erfindungsgemäß vorgeschlagen, daß der Schild in Längsrichtung der Kanüle in verschiedenen Positionen fixierbar an der Kanüle angebracht ist.The document DE 197 39 103 A1 discloses a tracheotomy cannula consisting of a tubular or tubular element for passage through a cervical and tracheotomy into the trachea of a patient when its upper respiratory tracts are blocked in order to deliver the patient through the cannula with breathing air and with a shield attached to the cannula, by its abutment on the neck of the patient, the position of the cannula or the end of the cannula in the trachea of the patient is defined. To provide a tracheostomy tube with the features mentioned above, which is easily adaptable to the anatomical conditions present in a patient and causes no major effort in terms of storage and adaptation of tracheostomy tubes, the invention proposes that the shield in the longitudinal direction of the cannula In various positions fixable attached to the cannula.
Der Nachteil dieser Tracheotomiekanülen ist, dass das bewegliche Schild nur in Längsrichtung verschoben werden kann.The disadvantage of these tracheostomy tubes is that the movable shield can only be displaced in the longitudinal direction.
Aus der Schrift DE 195 14 433 Cl ist eine Tracheostomiekanüle zum Einsatz in ein Tracheostoma bekannt, welche eine schlauchförmige Außenkanüle, in welche eine ebenfalls schlauchförmige Innenkanüle fuhrbar und mit der Außenkanüle am proximalen Teil verriegelbar ist, um ein Kanülenrohr zu bilden, aufweist, wobei im proximalen Bereich der Außenkanüle ein Kanülenschild zur Anlage am Hals angebracht ist, durch welches hindurch der proximale Teil der Außenkanüle greift und das Kanülenrohr gegenüber dem Kanülenschild um wenigstens zwei Raumachsen verschwenkbar gelagert ist. Der Nachteil dieser Tracheotomiekanülen ist, dass das bewegliche Schild über keine freie Schwenk- und Drehbarkeit in sämtliche Raumrichtungen verfügt und dass sie eine mechanische Instabilität bei Dauerbelastung aufweisen.From the document DE 195 14 433 Cl a tracheostomy tube for use in a tracheostoma is known, which has a tubular outer cannula into which a likewise tubular inner cannula is guided and can be locked to the outer cannula at the proximal part in order to form a cannula tube proximal portion of the outer cannula a cannula shield is attached to the neck, through which engages the proximal portion of the outer cannula and the cannula tube is mounted relative to the cannula plate pivotable about at least two spatial axes. The disadvantage of these tracheostomy tubes is that the movable shield has no free pivoting and rotation in all Has spatial directions and that they have a mechanical instability under continuous load.
Der Erfindung liegt daher die Aufgabe zu Grunde, die Nachteile des Standes der Technik zu vermeiden, insbesondere eine Trachealkanüle mit beweglichem Schild anzugeben, die eine freie Schwenk- und Drehbarkeit in sämtliche Raumrichtungen ermöglicht und auch bei Dauerbelastung eine hohe mechanische Stabilität aufweist.The invention is therefore based on the object to avoid the disadvantages of the prior art, in particular to provide a tracheostomy tube with a movable plate, which allows free pivoting and rotation in all directions and also has a high mechanical stability under continuous load.
Gemäß der Erfindung wird diese Aufgabe durch die Merkmale des ersten Patentanspruchs gelöst und durch die Merkmale der Unteransprüche vorteilhaft ausgestaltet.According to the invention, this object is solved by the features of the first claim and advantageously designed by the features of the subclaims.
