Description

  • Pumpvorrichtung für medizinische Geräte Die Erfindung betrifft eine medizinische Pumpvorrichtung und kennzeichnet sich im wesentlichen dadurch, daß ein drehbarer zylindrischer Körper mit einem Schraubengang versehen ist, welcher auf eine nachgebende, z. B. aus einzelnen Streifen oder Gliedern bestehende Unterlage drückt.
  • Ein weiteres Merkmal der Erfindung ist, daß die von dem Schraubengang gedrückte Unterlage den Druck auf ein elastisches, z. B. aus Gummi bestehendes Rohr weiterleitet.
  • Die Erfindung ist in der Zeichnung beispielsweise dargestellt.
  • Es zeigen: Fig. i eine Seitenansicht der Pumpe, teilweise im Schnitt, Fig. 2 eine Draufsicht der Pumpe, 'Fig. 3 einen Schnitt A-A der Fig. i.
  • Ein rotierender Zylinder i ist auf einer Achse 3 angeordnet und mit einem Schraubengang 2 versehen, welcher gegen eine aus einzelnen Streifen oder Gliedern bestehende Unterlage q. drückt. Zwischen der Unterlage q., deren einzelne Glieder um die Achse io schwenkbar sind, und einer festen Grundplatte 6 ist ein Rohr 5 aus Gummi oder einem anderen elastischen Stoffvorgesehen.
  • Beim Drehen des Zylinders i in der Pfeilrichtung wird der Schraubengang das Gummirohr vom Punkt 7 nach rechts zusammendrücken, wodurch im Punkt 8 eine Stauung bzw. ein T,%erdruck erzeugt wird, während im Punkt 9 kein Druck vorherrscht.
  • Gemäß der Erfindung ist es möglich, durch eine einfache Vorrichtung eine in einem Schlauch o. dgl. fließende Flüssigkeit zu beschleunigen bzw. unter einen gewissen Druck zu setzen, was z. B. bei Bluttransfusionen erwünscht ist.
  • Im anderen Falle kann die Pumpvorrichtung auch als Saugvorrichtung verwendet werden.
