Bekannt ist, daß Beatmungspatienten nur durch manuelles Verschließen einer Öffnung an der Beatmungskanüle, die in die Luftröhre eingeführt ist, die zum Sprechen nötige Luft erhalten. In den meisten Fällen ist ein Beatmungspatient so hochgradig querschnittsgelähmt, daß er nicht selber die Kanüle bedienen kann. Hierzu bedarf es einer zusätzlichen Person, auf die der Beatmungspatient folglich angewiesen ist. Darüber hinaus trocknet die Kehle des Beatmungspatienten sehr schnell aus, so daß nur ein kurzes Sprechen ermöglicht wird.The present invention relates to a device according to the Preamble of claim 1 for language support from Respiratory patients. It is known that respiratory patients only by manually closing an opening on the Respiratory cannula, which is inserted into the trachea, leading to the Speak necessary air. In most cases it is a Respiratory patient so paraplegic that he cannot operate the cannula itself. This requires one additional person to whom the respiratory patient consequently is instructed. It also dries the throat of the Respiratory patients very quickly, so that only a short one Speaking is made possible.

Aufgabe der Erfindung ist es, dem Patienten das selbständige und andauernde Sprechen zu ermöglichen.The object of the invention is to make the patient independent and enable ongoing speaking.

Diese Aufgabe wird durch das Gerät mit den Merkmalen des Anspruchs 1 gelöst. Der Anwender kann trotz seiner Lähmung selbsttätig (ohne Fremdeinwirkung) das Gerät betätigen, das Gerät selber arbeitet dann vollautomatisch. Außerdem wird durch das Gerät dem Austrocknen der Kehle wirksam vorgebeugt.This task is performed by the device with the characteristics of Claim 1 solved. Despite his paralysis, the user can  operate the device automatically (without external influence) The device itself then works fully automatically. Besides, will effectively prevents the throat from drying out.

Der Anwender erfährt somit eine erhebliche Erhöhung der Lebensqualität, indem er nicht nur kurz seine Grundbedürfnisse äußern kann, sondern ferner auch an Gespräche und Diskussionen aktiv teilnehmen kann. Dies stellt für den beatmeten Gelähmten eine wichtige Grundvoraussetzung dar, trotz der extremen körperlichen Erschwernis einer Beschäftigung nachzugehen.The user thus experiences a significant increase in Quality of life by not only briefly describing its basic needs can express, but also in discussions and discussions can actively participate. This represents the paralyzed man being ventilated an important basic requirement, despite the extreme physical difficulties to pursue employment.

Weiterhin ist von Vorteil, daß das Gerät durch Anschluß an eine Batterie mobil einsetzbar ist. Der Behinderte ist somit nicht an externe Stromquellen gebunden. Darüber hinaus beansprucht die kompakte Bauweise in Verbindung mit der lageunabhängigen Betriebsweise des Gerätes einen minimalen Platzaufwand und vereinfacht somit den Einsatz auch an elektrischen Rollstühlen.Another advantage is that the device can be connected to a battery can be used mobile. The disabled is therefore not tied to external power sources. Furthermore claims the compact design in connection with the location-independent operation of the device a minimal Space requirements and thus also simplifies use electric wheelchairs.

Über Schnittstellen läßt sich die Erfindung erweitern, um somit zusätzliche Kontrollfunktionen wie z. B. die Überwachung des Ladezustandes der Batterie für das Beatmungsgerät oder den elektrischen Rollstuhl zu erhalten, oder, um zusätzliche Mechanismen wie etwa Blutdruckmessung in festgelegten Zeitintervallen zu ermöglichen.The invention can be expanded via interfaces to thus additional control functions such. B. monitoring the state of charge of the battery for the ventilator or the electric wheelchair, or to get additional Mechanisms such as blood pressure measurement in specified To allow time intervals.

Ein Ausführungsbeispiel ist nachfolgend beschrieben.An embodiment is described below.

Mittels Kompressoren wird Luft aus der Umgebung angesaugt und über Reinigungsfilter und ein Luftbefeuchtungssystem geleitet. Sodann tritt die gereinigte und befeuchtete Luft an einem Schlauchanschluß auf der Frontseite aus. Hier wird über einen Schlauch das Gerät mit der Beatmungskanüle verbunden. Zum Anschluß des Geräts ist folglich kein zusätzlicher Eingriff in den Organismus des Beatmungspatienten nötig. Über ein speziell aufgebautes Mikrofon wird das Gerät durch ein Zungenschnalzen bedient. Hierzu wird das Gerät einmalig den Bedürfnissen des Patienten angepaßt. Das Luftbefeuchtungssystem besteht aus einem kleinen Wassertank, aus dem mittels Kapillarwirkung destilliertes Wasser auf einen Schwamm gelangt, durch den die Luft geleitet und somit befeuchtet wird.Air is sucked in from the environment by means of compressors passed through cleaning filters and an air humidification system. Then the cleaned and humidified air comes on one Hose connection on the front. Here is about one Hose connected the device to the ventilation cannula. To the Connection of the device is therefore no additional intervention in the respiratory patient's organism is necessary. About a special built-in microphone, the device is a tongue snapping served. For this, the device is unique to the needs of  Adapted to patients. The humidification system consists of a small water tank from which capillary action distilled water on a sponge through which the Air is conducted and thus humidified.

Die Stromzufuhr kann entweder über ein Netzteil vom Hausstrom erfolgen, oder direkt über die 12V-Batterie des elektrischen Rollstuhls. Um zu verhindern, daß der Anwender durch Verschlucken einen Überdruck erfahren kann, ist zur Sicherheit ein Staudrucksensor eingebaut, welches das Gerät dann automatisch abschaltet. Zudem kann die Empfindlichkeit des Mikrofons geregelt werden, so daß auch leisere Schnalzgeräusche zur Bedienung des Gerätes ausreichen. Das Mikrofon muß dabei nicht direkt vor dem Mund des Patienten angebracht sein, sondern kann wie ein übliches Krawattenmikrofon befestigt werden.The power supply can either via a power supply from the house power take place, or directly via the 12V battery of the electrical Wheelchair. To prevent the user from Ingestion can experience overpressure is for safety a dynamic pressure sensor installed, which the device then automatically switches off. In addition, the sensitivity of the Microphones are regulated so that even quieter ones Clicking noises are sufficient to operate the device. The The microphone does not have to be directly in front of the patient's mouth be attached, but can be like a usual Tie microphone can be attached.

Die Anschlußkabel des Mikrofons und der Stromquelle sind verriegelbar, ebenso der Einstellknopf für die Mikrofonempfindlichkeit. Luftdruck und Luftüberdrucküberwachung können nur mit einem Schraubenzieher verändert werden. Durch diese Fixierung des Betriebszustandes wird eine ungewollte Veränderung verhindert bzw. erschwert. Das obere Anzeigeinstrument dient der Kontrolle der Mikrofonempfindlichkeit sowie des Wasserfüllstandes. Die untere Anzeige dient der Zustandskontrolle der angeschlossenen Stromquelle bzw. Batterie.The connection cables of the microphone and the power source are lockable, as well as the adjustment button for the Microphone sensitivity. Air pressure and Air pressure monitoring can only be done with a screwdriver to be changed. By fixing the operating status an unwanted change is prevented or made more difficult. The upper display instrument is used to control the Microphone sensitivity and the water level. The The lower display is used to check the status of the connected Power source or battery.
