Description

Beschreibung Bei der Bestimmung der Blutkorperchensenkungsgeschwindigkeit (BSG) nach Westergren wird der Senkungsgrad der roten Blutkörperchen in einer bestimmten Zeit (1 u. 2 Stunden) gemessen.Description When determining the blood sedimentation rate (BSG) according to Westergren is the lowering degree of the red blood cells in a certain Time (1 and 2 hours) measured.

Dazu wird durch Zusatz von Natriumzitrat ungerinnbar gemachtes Blut in ein transparentes röhrchen kGlas od. Kunststoff) von 2,5 mm innerem Durchmesser und mindestens 20 cm Dänge gefiillt, dises senkrecht aufgestellt und nach Ablauf der vorgeschriebenen Zeit der Senkungsgrad der roten blutkörperchen an einer an dem Röhrchen angebrachten @kala (1 - 200) festgestellt.For this purpose, blood made incoagulable by adding sodium citrate in a transparent tube (glass or plastic) with an inner diameter of 2.5 mm and filled at least 20 cm in length, set it up vertically and after it has run out at the prescribed time the level of subsidence of the red blood cells on one @ scale (1 - 200) attached to the tube.

nei den bisher gebräuchlichen Vorrichtungen werden die möhren entweder mit Hilfe von Saugvorrichtungen (aufsetzbare Summisauger ,eingeschliffene stempel etc.) oder über lose Ansatzstücke, die bei entsprechender verschiebung gegenüber der Röhrchenöffnung entweder eine Füllfunktion oder eine Verschlussfunktion übernehmen, mit Blut gefüllt. Der Ständer hat hierbei durch festes Aufdrücken der röhrchen auf ein verschlusspolster (meist aus Gummi) wesentlichen Anteil an der Verschlussfunktion.With the devices in use up to now, the carrots are either With the help of suction devices (attachable summit suction cups, ground-in stamps etc.) or via loose extension pieces, which, if shifted accordingly, are opposite the tube opening either have a filling function or a sealing function, filled with blood. The stand is opened by firmly pressing the tubes A locking pad (mostly made of rubber) plays an important role in the locking function.

Bei dem hier angemeldeten Senkungsröhrchen entfallen alle zusätzlichen flechanismen für Füllung und Verschluss, die zudem bei ungeschickter Bedienung eine zusätzliche Fehlerquelle bilden können. Die Röhre ist an ihrem unteren Ende mit einem Ventllmechanismus versehen, der einerseits eine Füllung mit Blut direkt aus der Sp[ritze erlaubt und andererseits automatisch die Verschlusefunktion übernimmt. Je nach Art des ventils - aufsteckbar oder fest mit der Röhre verbunden - wird diese ein- oder mehrmals verwendet. Es kommen die bekannten Ventilmechanismen in trage.In the case of the subsidence tube registered here, all additional ones are omitted flechanisms for filling and closure, which also cause a can be an additional source of error. The tube is at its lower end with provided a valve mechanism, which on the one hand a filling with blood directly from the tip and on the other hand automatically takes over the locking function. Depending on the type of valve - attachable or permanently connected to the tube - this is used one or more times. The known valve mechanisms come into play.

Die Ventil- und Verschlussfunktion kann auch von einen elastisehen Material kwie z.B. Gummi) übernommen werden, das das Röhrehen am unteren Ende verschliesst; es wird mit der kanüle durchstochen, das Blut von unten her eingespritzt (wobei auch lorrekturen möglich aind) und dann die kanüle wieder herausgezogen, wobei dann das Röhrchen automatisch verschlossen wird Die Röhrchen brauchen darin nur noch senkrecht aufgestellt zu werden, jeder spezielle Halter ist überflüssig. Die Länge brsunkt der Röhrchen braucht dadurch, abweichend von den bisher gebräuchlichen Ausführungen, nur wenig mehr als 20 cm zu betragen. (s.Abb).The valve and closure function can also be seen from an elastic Material such as rubber) can be used, which closes the tube at the lower end; it is pierced with the cannula and the blood is injected from below (whereby corrections are also possible) and then the cannula is pulled out again, whereby then the tube is closed automatically The tubes only need in it To be set up vertically, any special holder is superfluous. The length As a result, the tube needs, in contrast to the previous versions, to be only a little more than 20 cm. (see picture).
