Description

Gerät zur künstlichen Atmung Die I,ekannten Geräte für Zwangsbeatmung werden durch eine Luftpumpe im Atemrhythmus alwechselnd unter Überdruck und Unterdruck gebracht. Die Luftpumpen sind dabei aus Sicherheitsgründen überdimensioniert. Damit der jeweils notwendige, auf die Atmungsorgane einwirkende Über-bzw. Unterdruck nicht überschritten wird, müssen entsprechende Vorrichtungen vorgesehen sein. Normale Uber-bzw. Unterdruckventile, die mit Feder-Belastung arbeiten, sind aus physiologischen Gründen nicht geeignet, da derartige Ventile bei einem I,estimmten Druck tief öffnen bzw. schließen und damit den stetigen Anstieg bzw. Abfall des an sich von der Luftpumpe erzeugten Drucks unterbrechen. In gleicher Weise werden die Luftgeschwindigkeiten beim Öffnen bzw. Schließen der Ventile unstetig geändert.Artificial respiration device The I recognized devices for forced ventilation are alternately under positive and negative pressure by an air pump in the breathing rhythm brought. The air pumps are oversized for safety reasons. In order to the respectively necessary over- or. Negative pressure not is exceeded, appropriate devices must be provided. Normal Uber or. Vacuum valves that work with spring loading are physiological Not suitable for reasons, as such valves open deeply at a certain pressure or close and thus the steady rise or fall of the per se of the air pump interrupt the pressure generated. In the same way, the air velocities changed discontinuously when opening or closing the valves.

Die Erfindung betrifft Geräte für künstliche Atmung und erstrebt eine stetige Veränderung des Luftdrucks. Gemäß der Erfindung steht der Druckraum des Gerätes über ein oder mehrere verstellbare Düsen mit der Außenluft in Verbindung. An die Stelle von Über- bzw. Unterdruckventilen treten also drosselnde Öffnungen, deren Strömungswiderstand die Druckhöhe in dem Gerät bestimmt. Die Düsen bzw. ihr Strömungswiderstand sind verstellbar. Bei dem erfindungsgemäßen Gerät wird also ein stetiger Druckverlauf erreicht. The invention relates to and seeks devices for artificial respiration a constant change in air pressure. According to the invention, the pressure space is of the device in connection with the outside air via one or more adjustable nozzles. Throttling openings are used instead of overpressure or vacuum valves, whose flow resistance determines the pressure head in the device. The nozzles or you Flow resistance are adjustable. In the device according to the invention is so a steady pressure curve is achieved.
