Description
Gerät zur Probenahme von Flüssigkeiten für diagnostische Zwecke Es ergeben sich bei der Diagnostik häufig Fälle, bei denen der Ort der Entnahme weit entfernt oder schlver erreichbar ist. Man hat sich z. B. bei der Probenahme von Wasser aus bestimmten Tiefen eines luftleeren Glasrohres bedient dessen umgebogene Spitze durch ein Fallgewicht in der verlangen Tiefe abgeschlagen wurde.Device for sampling liquids for diagnostic purposes It The diagnosis often results in cases in which the location of the removal is far distant or more difficult to reach. One has z. B. when sampling Water from certain depths of an evacuated glass tube serves the bent one Tip was knocked off by a drop weight in the required depth.
Ein anderer Weg, Proben zu entllehmen, ist folgender: Ein in eine Röhre ausmündender eiasti scher Hohlkörper nvird nach Entfernen der Luft an seinem röhrenförmigen Teil nach Umbiegen desselben durch einen Ring verschlossen gehalten. Another way to get samples is this: One in one The tube of the eiastic hollow body which empties into it is removed from the body after the air has been removed tubular part kept closed after bending it by a ring.
Dieser Ring wird aus einem Material hergestellt, das sich unter bestimmten Bedingungen löst. Diese Bedingungen sind beispielsweise die Temperatur-, die Wasserstoffionenkonzentrations- oder die Lösungsmittelkonzentrationsänderung in dem Bereich der Löslichkeit des Ringes. Nach Auflösen des Ringes kann das Vakuum des Hohlkörpers wirksam werden und die Probe ansaugen. Durch Vcntilverschluß kann das Rückfließen von Flüssigkeit verhindert werden.This ring is made from a material that is subject to certain Conditions solves. These conditions are, for example, the temperature, the hydrogen ion concentration or the change in solvent concentration in the range of solubility of the Ring. After the ring has dissolved, the vacuum in the hollow body can take effect and suck in the sample. The backflow of liquid can be prevented by a valve closure be prevented.
