The suction catheter (c) is secured to the outer curvature of the endotracheal tube (a) by an adhesive or welding. The suction catheter has two opening holes (7) at both sides in the pharyngeal cavity. The oropharyngeal tube is pref. made of a hard PVC.

Description

Die Erfindung bezieht sich auf eine Anordnung eines Endotrachealtubuses mit eingebautem Absaugkatheter gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an arrangement of a Endotracheal tubes with built-in Suction catheter according to the preamble of claim 1.

Eine solche Anordnung ist aus der DE 35 23 663 A1 bekannt.Such an arrangement is known from DE 35 23 663 A1.

Die Endotrachealtuben sind biegsame Rohre, die zur Narkosebeatmung von Patienten meistens durch den Mund in die Luftröhre geschoben werden. Sie bestehen aus gewebefreundlichen Kunststoffen wie Gummi oder PVC. Die Endotrachealtuben garantieren freie Atemwege. Sie sind in der überwiegenden Zahl mit einer aufblasbaren Blockermanschette 1 ausgestattet. Die Blockermanschette wird über einen kleinen Kanal, der in die Rohrwand eingearbeitet ist, mit der Raumluft aufgeblasen. Der Kanal geht in einen dünnen Schlauch 2 über, der sich außerhalb des Patienten zu einem Kontrollballon 3 erweitert. Der Kontrollballon endet mit einem Ventil und einem Ansatzstutzen 4 für eine Blockerspritze, über die die Blockermanschette aufgeblasen wird. Das Ventil verhindert, daß die Luft spontan aus dem Kontrollballon ausweicht.The endotracheal tubes are flexible tubes that are usually pushed through the mouth into the trachea for patient anesthesia ventilation. They are made of tissue-friendly plastics such as rubber or PVC. The endotracheal tubes guarantee free airways. The majority of them are equipped with an inflatable blocker cuff 1 . The blocker sleeve is inflated with the ambient air via a small channel that is built into the pipe wall. The channel merges into a thin tube 2 which expands into a control balloon 3 outside the patient. The control balloon ends with a valve and a connecting piece 4 for a blocker syringe, via which the blocker cuff is inflated. The valve prevents the air from spontaneously escaping from the control balloon.

Auf diese Weise wird der Patient während einer Narkose von einer Aspiration geschützt.In this way, the patient becomes aspirated during anesthesia protected.

Der Oropharyngealtubus hat eine gebogene Form, den anatomischen Verhältnissen im Mund angepaßt. Er ist aus hartem PVC hergestellt, und hat in der Mitte ein Lumen, durch den ein Absaugkatheter in den Rachenraum eingeführt werden kann. Der Oropharyngealtubus wird immer seitlich vom Endotrachealtubus plaziert, um den Endotrachealtubus vom Beißen der Patienten zu schützen und auf diese Weise den Gasaustausch zu ermöglichen.The oropharyngeal tube has a curved shape, the anatomical conditions adjusted in the mouth. It is made of hard PVC, and has in the middle a lumen through which a suction catheter is inserted into the pharynx can. The oropharyngeal tube is always on the side of the endotracheal tube placed to protect the endotracheal tube from patient biting and in this way to enable gas exchange.

Der Absaugkatheter ist ein flexibler Schlauch mit einem konischen Ansatz proximal (aboral) zum Anschluß an die Absaugvorrichtung. Das dem Kehlkopf zugewandte distale Ende endet im Rachenraum und weist meistens beidseitig vom distalen Lumen ein Loch auf. The suction catheter is a flexible tube with a conical approach proximal (aboral) for connection to the suction device. The larynx facing distal end ends in the pharynx and usually points open a hole on both sides of the distal lumen.  

Nach dem man den Patienten Narkosemittel und Muskelrelaxantien verabreicht hat, passiert manchmal, besonders bei den Patienten, die als Notfall operiert werden müssen (die sind oft nicht nüchtern), daß sie kurz vor der Einführung des Tubuses in die Luftröhre (Intubation) erbrechen müssen. Da die Reflexe gleichzeitig blockiert sind (die Stimmbänder sind offen), läuft Erbrochenes in die Lunge. Das kann den Tod des Patienten oder eine schwere Lungenentzündung (Aspirationspneumonie) verursachen, die oft zum Tode führt.After giving the patient anesthetics and muscle relaxants has happened sometimes, especially in patients who have an emergency have to be operated on (they are often not sober), that they are about Introduce the tube into the trachea (intubation). There the reflexes are blocked at the same time (the vocal cords are open), vomit runs into the lungs. That can be the patient's death or a severe pneumonia (aspiration pneumonia) that often cause leads to death.

Der Magensaft kann kurz vor der Intubation, auch bei den Patienten die nüchtern sind, spontan in den Rachenraum landen und durch die Luftröhre in die Lunge eindringen (stille Aspiration).The gastric juice can also be given to patients just before intubation are sober, spontaneously land in the throat and through the windpipe penetrate into the lungs (silent aspiration).

In den beiden Fällen muß man die Intubation unterbrechen und den Rachenraum absaugen. Leider ist das oft zu spät, da die Patienten, bevor man den zweiten Intubationsversuch startet, schon aspiriert haben.In both cases the intubation has to be interrupted and the Vacuum the throat. Unfortunately, this is often too late since the patient before you start the second intubation attempt, have already aspirated.

Der Absaugketheter kann in diesem Fall auch seine Funktion nicht erfüllen.In this case, the suction cheter cannot fulfill its function.

Es ist daher Aufgabe der Erfindung, die Anordnung der eingangs genannten Art derart auszubilden, daß die Gaszuführung möglichst nicht durch den Patienten beeinträchtigt werden kann und das Absaugen von Flüssigkeit auch während der Intubation möglich sein soll.It is therefore an object of the invention, the arrangement of those mentioned Form in such a way that the gas supply as possible not through the Patients can be affected and suction of fluid should also be possible during intubation.

Gelöst wird diese Aufgabe durch die im Patentanspruch 1 dazu angegebenen Merkmale. Eine besondere Ausführungsart der Erfindung ist im Unteranspruch angegeben.This object is achieved by the specified in claim 1 Features. A special embodiment of the invention is in Subclaim specified.

Um eine Aspiration zu verhindern, ist an die äußere Krümmung des Endotrachealtubuses ein Absaugkatheter angeklebt oder angeschweißt. Der Absaugkatheter hat an dem am Kehlkopf zugewandte Ende (distal) ein Lumen und beidseitig zwei Löcher, so daß er an der Schleimhaut im Rachenraum nicht klebt. Zur Erläuterung wird auf das in den Fig. 1 und 2 dargestellte Ausführungsbeispiel verwiesen.To prevent aspiration, a suction catheter is glued or welded to the outer curvature of the endotracheal tube. The suction catheter has a lumen at the end facing the larynx (distal) and two holes on both sides, so that it does not stick to the mucous membrane in the pharynx. For explanation, reference is made to the embodiment shown in FIGS. 1 and 2.

An dem proximalen konischen Ansatz (aboralen) wird die Absaugvorrichtung angeschlossen, um den Magensaft oder das Erbrochene sofort bei dem ersten Intubationsversuch absaugen zu können.The suction device is attached to the proximal conical attachment (aboral) connected to the gastric juice or the vomit immediately at the first To be able to aspirate intubation.

Meistens, im Aufwachstadium, beißt der Patient die Zähne zusammen. Dadurch wird die Zufuhr von Sauerstoff und den Narkosegasen blockiert.Most often, in the waking up stage, the patient grits his teeth. Thereby the supply of oxygen and the anesthetic gases is blocked.

Um die Versorgung des Patienten mit dem Sauerstoff und den Narkosegasen zu gewährleisten, wird der Oropharyngealtubus benutzt. Er ist aus hartem PVC hergestellt und hat in der Mitte einen Kanal 5 für den Endotrachealtubus und einen weiteren Kanal 6 für den Absaugkatheter. Auf diese Weise umhüllt der Oropharyngealtubus den Endotrachealtubus und den Absaugkatheter. The oropharyngeal tube is used to ensure that the patient is supplied with oxygen and anesthetic gases. It is made of hard PVC and has a channel 5 in the middle for the endotracheal tube and another channel 6 for the suction catheter. In this way, the oropharyngeal tube envelops the endotracheal tube and the suction catheter.

Da die Krümmung des außenstehenden Oropharyngealtubuses der Krümmung des innenstehenden Endotrachealtubuses und des Absaugkatheters entspricht, ist er entlang des Endotrachealtubuses und des Absaugkatheters beweglich. Nach der Intubation wird der Oropharyngealtubus, der von der Intubation aboral (proximal) gezogen wird, nach distal (kaudal) bewertet, bis der gekrümmte Teil zwischen den Zähnen liegt und die Fläche, die rechtwinklig auf den gebogenen Teil des Oropharyngealtubuses aufgesetzt ist, die Außenseite beider Lippen berührt. In dieser Lage werden der Endotrachealtubus und der Oropharyngealtubus an die Wange mit der Hilfe eines Pflasters fixiert.Since the curvature of the external oropharyngeal tube corresponds to the curvature of the corresponds to the internal endotracheal tube and the suction catheter, it is movable along the endotracheal tube and the suction catheter. After the intubation, the oropharyngeal tube is separated from the intubation pulled aborally (proximally), rated distally (caudally) until the curved Part lies between the teeth and the surface that is perpendicular to the curved part of the oropharyngeal tube is placed on the outside touched both lips. In this position, the endotracheal tube and the oropharyngeal tube to the cheek with the help of a plaster fixed.

Den Endotrachealtubus mit eingebautem Oropharyngealtubus und einem Absaugkatheter (EOAK) kann man einfach benutzen und den Rachenraum vollständig absaugen, da der Absaugkatheter optimal eingebaut ist.The endotracheal tube with built-in oropharyngeal tube and one Suction catheter (EOAK) can be used easily and the pharynx completely aspirate as the suction catheter is optimally installed.

Der EOAK ermöglicht das Absaugen des Rachenraumes auch während der Operatiaonen (keine Tamponade notwendig).The EOAK enables the throat to be suctioned off even during the Operations (no tamponade necessary).

Statt drei Teile, die für eine Intubationsnarkose notwendig sind, braucht man nur einen Teil, in dem alle drei Teile enthalten sind.Instead of three parts, which are necessary for an intubation anesthesia one part that contains all three parts.

Die werden gleichzeitig benutzt und am Ende einer Narkose gleichzeitig entfernt und entsorgt.They are used at the same time and at the end of anesthesia at the same time removed and disposed of.
