 geregelt werden kann. Nach entsprechender Einstellung der Feder   p liegt   das Kurvenstück mit einer seiner Gleitflächen mit federndem Druck gegen die Rolle des Hebels 13. Solange Saugund Druckwirkung gering sind, wird der Blasebalg/1 durch diese Einrichtung in seiner oberen bezw. unteren Endstellung festgehalten, je nachdem das Hebelende sich auf der Gleitfläche   o'   bezw. o2 befindet.

   Wird der Balg infolge genügender Saug-oder Druckwirkung ein wenig   über   die Mitte hinüber bewegt, so gleitet das freie Ende des Hebels 13 von der einen Gleitfläche   ei   über die Spitze des Kurvenstückes auf die andere   Gleitfäche o oder umgekehrt,   der Blasebalg schnellt durch die Kraft der Feder p0 in seine andere Endstellung und bewegt auf diese Weise sehr schnell

PATENT-ANSPRÜCHE :

  
1.   Einrichtung zum selbsttätigen Umsteuern   der Luft-Druck- und Saugperioden bei Vorrichtungen zur Erzeugung künstlicher Atmung nach den Patenten Nr. 41364 und Nr.   41. 65.   dadurch gekennzeichnet, dass der drückende Luftsrom, wenn seine Kraft nach ganz oder nahezu 
 EMI2.3 
 steuert und der saugende Luftstrom, wenn seine Kraft nach ganz oder nahezu erfolgter Entleerung der Atmungsorgane voll zur Wirkung kommt, von der Saug-in die Druckperiode umsteuert.

 can be regulated. After appropriate adjustment of the spring p the curve piece is with one of its sliding surfaces with resilient pressure against the roller of the lever 13. As long as suction and pressure are low, the bellows / 1 is by this device in its upper or lower end position held, depending on the end of the lever on the sliding surface o 'respectively. o2 is located.

   If the bellows is moved a little over the center as a result of sufficient suction or pressure, the free end of the lever 13 slides from one sliding surface ei over the tip of the curved piece to the other sliding surface o or vice versa, the bellows snap by the force of Spring p0 in its other end position and moves very quickly in this way

PATENT CLAIMS:

  
1. Device for automatic reversal of the air pressure and suction periods in devices for generating artificial respiration according to patents no. 41364 and no. 41. 65. characterized in that the pressing air flow when its force is completely or almost
 EMI2.3
 controls and the sucking air flow, when its power comes to full effect after complete or almost complete emptying of the respiratory organs, reverses from the suction to the pressure period.

Claims (1)

2. Eine Vorrichtung nach Anspruch 1, gekennzeichnet durch einen Balg, welcher mit der Druck-und Saugleitung und dem Luftweg-Umsteuerungsorgan derart verbunden ist, dass er durch den voll wirkenden Luftstrom bewegt wird und dabei die Umsteuerung veranlasst. 2. A device according to claim 1, characterized by a bellows which is connected to the pressure and suction line and the airway reversing member in such a way that it is moved by the fully effective air flow and thereby causes the reversal. 3. Eine Ausführungsform der Vorrichtung nach Anspruch 2, dadurch gekennzeichnet. dass die durch den voll wirkenden Luftstrom veranlasste Bewegung des Balges durch eine Feder und eine von letzterer beeinflusste, auf einen Hebel einwirkende keilförmige Kurve beschleunigt wird, um die Umsteuerung ohne Verzögerung zu bewirken. EMI2.4 3. An embodiment of the device according to claim 2, characterized. that the movement of the bellows caused by the fully effective air flow is accelerated by a spring and a wedge-shaped curve, influenced by the latter and acting on a lever, in order to effect the reversal without delay.
