Description
Die Verknüpfung der genannten Ergänzungen zur erfindungsgemäßen Anordnung ist in Fig. 1 dargestellt. Nachfolgend wird nunThe linkage of said additions to the arrangement according to the invention is shown in FIG. Below is now
die erfindungsgemäße Anordnung zur Überwachung/Steuerung der Beatmung in offenen Beatmungssystemen erläutert. Am Ende werden bei Erkennung der zugehörigen Gefahrenzustände für das zu beatmende Lebewesen die Signale Havarie-Inspirium oder Havarie-Exspirium bei Grenzwertüber- oder -unterschreitung bereitgestellt.the arrangement according to the invention for monitoring / controlling the ventilation in open ventilation systems explained. In the end, the signals Havarie-Inspirium or Havens-Exspirium are provided when the limit value is exceeded or exceeded if the associated dangerous states for the living organism to be ventilated are detected.
Die Anwendung der erfindungsgemäßen Anordnung ohne zusätzlichen Meßschlauch ist gebunden an eine bekannte Injektorbeatmungsanordnung, wobei die zur Realisierung der erfindungsgemäßen Anordnung erforderlichen Ergänzungen DrucktriggerT, zwei UND-Verknüpfungsgatter G1, G 2, zwei Speicher FF1, FF2 sowie zwei Zeitgeber ZG1, ZG 2 erläutert werden.The application of the arrangement according to the invention without additional measuring hose is bound to a known Injektorbeatmungsanordnung, wherein the necessary to realize the inventive arrangement supplements DrucktriggerT, two AND gates G1, G2, two memory FF1, FF2 and two timers ZG1, ZG 2 are explained.
Eine Injektorbeatmung wird unter anderem bei der Diagnostik, bei der chirurgischen Behandlung gutartiger organischer Veränderungen des Kehlkopfes und bei der Früherkennung des Kehlkopfkarzinoms eingesetzt.Injector ventilation is used, inter alia, in diagnostics, in the surgical treatment of benign organic changes of the larynx and in the early detection of laryngeal carcinoma.
Der Eingang des Drucktriggers T ist mit der Drucksteuerleitung des üblichen Injektors, beispielsweise durch ein normales T-Stück, verbunden. Ist der Druck am Eingang des Drucktriggers T größer als seine Triggerschwelle, so wird das Ausgangssignal gebildet. Der am Eingang des Drucktriggers T anliegende Druck entspricht nicht dem Lungeninnendruck, sondern er ist kleiner, hängt aber eindeutig vom Lungeninnendruck ab. Die Triggerschwelle sollte so niedrig wie möglich eingestellt werden, wobei sie dann aber nicht durch kleinste, aber zulässige Druckschwankungen erreicht werden darf. Für das Ausführungsbeispiel erwiesen sich 10 mm WS als gut geeignet.The input of the pressure trigger T is connected to the pressure control line of the conventional injector, for example by a normal tee. If the pressure at the input of the pressure trigger T is greater than its trigger threshold, the output signal is formed. The pressure applied at the entrance of the pressure trigger T does not correspond to the internal pressure of the lungs, but is smaller, but clearly depends on the internal pressure of the lungs. The trigger threshold should be set as low as possible, but then it must not be achieved by the smallest, but allowable pressure fluctuations. For the embodiment, 10 mm of WS proved to be well suited.
Die beiden Speicher FF1, FF2 müssen im Grundzustand sein, das heißt, am Ausgang wird kein Signal gebildet.The two memories FF1, FF2 must be in the ground state, that is, no signal is formed at the output.
Die Zeitgeber ZG1, ZG 2 bilden, beginnend mit dem Anliegen eines Signals am Starteingang, während der Dauer der Verzögerungszeit am Ausgang ein Ausgangssignal. Die Startsignale für die Zeitgeber ZG1, ZG 2 müssen von der Injektorbeatmungssteuerung bereitgestellt werden, was problemlos ist. Dabei wird der erste bei einer ersten Beatmungsphase und der zweite bei einer zweiten Beatmungsphase gestartet. Die von den Zeitgebern ZG1, ZG 2 bereitgestellten Signale können ebenso problemlos auch von anderen Einrichtungen gebildet werden. Besonders günstig ist es, wenn sie gleich von der Steuerung bereitgestellt werden.The timers ZG1, ZG 2, starting with the presence of a signal at the start input, during the duration of the delay time at the output an output signal. The start signals for the timers ZG1, ZG 2 must be provided by the injector ventilation control, which is easy. The first is started during a first ventilation phase and the second during a second ventilation phase. The signals provided by the timers ZG1, ZG 2 can also be easily formed by other devices. It is particularly advantageous if they are provided immediately by the controller.
Die Verzögerungszeit des ersten Zeitgebers ZG1 wurde zu 200 ms gewählt, die des zweiten Zeitgebers ZG 2 zu 81 % der Zeitdauer eines kompletten Atemzyklus. Diese Verzögerungszeiten sind an die Lungenparameter eines Normalpatienten angepaßt. Der erste Zeitgeber ZG1 wird am Ende der Inspiration gestartet. Der zweite Zeitgeber ZG 2 wird am Beginn der Inspiration gestartet.The delay time of the first timer ZG1 was set to 200 ms, that of the second timer ZG 2 to 81% of the time of a complete breathing cycle. These delay times are adapted to the lung parameters of a normal patient. The first timer ZG1 is started at the end of inspiration. The second timer ZG 2 is started at the beginning of inspiration.
