Description
PATENTAMT.PATENT OFFICE.
Bei den bisher bekannt gewordenen Spritzen für medicinische Zwecke wird durch das Vorstofsen des Kolbens die Flüssigkeit in einem ungleichmäfsigen Strahl ausgetrieben, da infolge der ungleichen Reibungswiderstände der Druck auf die Flüssigkeit ein ungleicher ist.In the previously known syringes for medical purposes, the Vorstofsen of the piston expelled the liquid in an uneven jet, as a result due to the unequal frictional resistance, the pressure on the liquid is unequal.
Die vorliegende Erfindung" soll nun das Ausspritzen eines vollkommen gleichmäfsigen Flüssigkeitsstrahles dadurch hervorbringen, dafs der Kolben a, wie die beiliegende Zeichnung zeigt, an einer steilgängigen Schraubenspindel (Drillbohrspindel) b befestigt ist, deren Mutter sich in dem oberen Verschlufsstück c des Spritzencylinders d befindet. Die Spindel ist mit ihrer Spitze e im Griff/ drehbar gelagert.The present invention "is intended to produce a completely uniform jet of liquid by the fact that the piston a, as the accompanying drawing shows, is attached to a steep screw spindle (drill spindle) b , the nut of which is located in the upper locking piece c of the syringe cylinder d . The spindle is mounted with its tip e in the handle / rotatable.
Nach der beiliegenden Zeichnung wird dies dadurch erreicht, dafs der Rand g nach Einführen der Spitze in die Griffbohrung in die Ringnuth h eingedrückt wird. Es ist klar, dafs beim Abwärtsschieben des Kolbens die Spindel b sammt dem daran befestigten Kolben in gleichmäfsige Drehung versetzt wird, so dafs der aus der Spitze fliefsende Flüssigkeitsstrahl ein sehr gleichmäfsiger sein wird.According to the accompanying drawing, this is achieved in that the edge g is pressed into the ring groove h after the tip has been inserted into the handle bore. It is clear that when the piston is pushed down, the spindle b, together with the piston attached to it, is set in uniform rotation, so that the jet of liquid flowing out of the tip will be a very uniform one.
