KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es sind Vorrichtungen zur Erzeugung künstlicher Atmung bekannt, bei denen mit einer ständig arbeitenden Luftsaugepumpe eine an die Druckgasleitung angeschlossene Sauerstoffflasche verbunden ist, wobei die abwechselnde Verbindung der den Anschluß an die Atmungswege vermittelnden Teile mit der Druckleitung und der Saugleitung durch einen Dreiwegehahn bewirkt wird.There are devices for generating artificial respiration are known in which with a constantly working air suction pump connected to the compressed gas line Oxygen cylinder is connected, the alternating connection of the connector to the parts communicating the respiratory tract with the pressure line and the suction line a three-way cock is effected.
ίο Demgegenüber besteht die vorliegende Erfindung darin, daß die Druckleitung von einer Sauerstoffflasche gespeist wird, während an die Saugleitung eine von Hand zu bedienende Luftpumpe angeschlossen ist, deren Kolbenbewegung gleichzeitig die Umstellung der Ventile bewirkt, indem das Saugventil der Luftpumpe in seiner Schlußstellung ein in die Druckleitung eingeschaltetes Ventil geöffnet erhält, das bei Öffnung des Saugventiles sich selbsttätig wieder schließt.In contrast, there is the present invention in that the pressure line is fed from an oxygen cylinder while on the suction line is connected to a manually operated air pump, the piston movement of which at the same time the changeover of the valves is effected by placing the suction valve of the air pump in its final position in the pressure line receives the switched-on valve opened when the suction valve is opened closes again automatically.
Die Zeichnung zeigt den Erfindungsgegenstand in einem Ausführungsbeispiel.The drawing shows the subject matter of the invention in an exemplary embodiment.
Die Gesichtsmaske 1. ist durch die Leitung 2 mit dem üblichen Ausgleichsbeutel 3 und der Sauerstoffflasche 4 verbunden, deren Reduzierventil 5 für einen immer gleichmäßigen Zuflußdruck des Sauerstoffes sorgt. Die Saugleitung 6, die erheblich weiter ist als die Druckleitung 2, setzt sich durch den Stutzen 7 bis zu der Membranpumpe 8 fort, die mittels eines Handgriffes 9 bedient wird.The face mask 1. is through the line 2 with the usual compensation bag 3 and the oxygen cylinder 4 connected, the reducing valve 5 for an always uniform The supply pressure of the oxygen ensures. The suction line 6, which is considerably wider than the pressure line 2, continues through the nozzle 7 to the diaphragm pump 8, which is operated by means of a handle 9.
In die Druckleitung 2 ist ein Ventil ro eingeschaltet, das durch eine Feder II auf seinen Sitz gedrückt wird. Über dem Ventil 10 ist das Saugventil 12 der Membranpumpe 8 angebracht. Das Ventil 12 drückt auf einen Führungsstift 13 des Ventiles 10, so daß bei geschlossenem Ventil 12 das Ventil 10 geöffnet wird und umgekehrt.In the pressure line 2, a valve ro is switched on, which is opened by a spring II his seat is pressed. The suction valve 12 of the diaphragm pump 8 is located above the valve 10 appropriate. The valve 12 presses on a guide pin 13 of the valve 10, so that at closed valve 12, the valve 10 is opened and vice versa.
Die Membranpumpe 8 bläst durch das Druckventil 14 aus. Ein Sicherheitsventil 15 sorgt dafür, daß der Druck innerhalb der Maske 1 niemals das zulässige Maß überschreiten kann.The diaphragm pump 8 blows out through the pressure valve 14. A safety valve 15 ensures that the pressure within the mask 1 never exceeds the permissible level can.
