Description
Bei der Bestimmung der Blutsenkungsgeschwindigkeit von Blutkörperchen nach der Methode von vestergren wird das zu untersuchende Blut mit dem Mund in eine kalibrierte Pipette gesaugt und deren obere Offnung danach mit dem Finger verschlossen. So dann läßt man das Blut bis zu einer Nullmarke absinken und setzt die Pipette auf eine abdichtende Gummiplatte in ein Gestell. Das richtige Einstellen des Nullpunktes der Blutsäule erfordert mitunter ein mehrmaliges Ansaugen, das nicht nur umständlich und unbequem, sondern wegen der moglichen Infektion auch gefährlich ist. In determining the rate of sedimentation of blood cells According to Vestergren's method, the blood to be examined is put into a mouth by mouth calibrated pipette sucked and its upper opening then closed with the finger. So then the blood is allowed to sink to a zero mark and the pipette is put in place on a sealing rubber plate in a frame. Correct setting of the zero point the column of blood sometimes requires repeated suction, which is not only cumbersome and inconvenient, but also dangerous because of the possible infection.
Um diese Nachteile zu vermeiden, hat man 7>ipetten mit besonderen Saugvorrichtungen versehen, die aber nicht verhindern, daß das die Pipetten aufnehmende Gestell mit infektiösem Blut verunreinigt wird. To avoid these disadvantages, you have 7> ipettes with special ones Provided suction devices, which, however, do not prevent the receiving of the pipettes The rack becomes contaminated with infectious blood.
Ein anderer Vorschlag geht dahin, das Blut durch ein ltückschlagventil in ein Meßröhrchen einzu-Spritzen. Diese Einrichtung ist schwer zu bedienen und schlecht zu reinigen. Another suggestion is to pass the blood through an oil check valve to be injected into a measuring tube. This facility is difficult to use and bad to clean.
Diese aufgezeigten Mängel werden in einfacher und einwandfreier Weise erfindungsgemäß dadurch vermieden, daß das untere Ende des Meßröhrchens kolbenartig in einem Zylinder verschieblich ist, der das zu untersuchende Blut enthält. Die Dichtung zwischen Kolben und Zylinder wirdi zweckmäßig durch Einschleifen hergestellt. Beim Verwenden von Glasteilen erhält man so èin leicht zu desinfizierendes Gerät. These identified shortcomings are presented in a simple and flawless manner avoided according to the invention in that the lower end of the measuring tube is piston-like is displaceable in a cylinder that contains the blood to be examined. the The seal between the piston and cylinder is expediently produced by grinding. When using glass parts, you get a device that is easy to disinfect.
Man benutzt die Vorrichtung in der Weise, daß man aus der Blutentnahmespritze etwa 1 ccm Blut in den Zylinder einbringt und dann das Meßröhrchen so weit hineingleiten läßt, bis das Blut zur Nullmarke emporgedrückt ist. The device is used in such a way that one withdraws from the blood collection syringe Introduces about 1 cc of blood into the cylinder and then slide the measuring tube into it leaves until the blood is pushed up to the zero mark.
In der Abbildung sind beispielsweise Ausführungsformen der Erfindung dargestellt. Exemplary embodiments of the invention are shown in the figure shown.
In einem Behälter befinden sich eine Anzahl von Zylindern, in die nach Einbringen des zu untersuchenden Blutes die Meßröhrchen eingeschoben werden. In a container there are a number of cylinders into which After introducing the blood to be examined, the measuring tubes are inserted.
Die Festlegung der Höhe der Blutsäule kann in verschiedener Weise erfolgen, was nicht Gegenstand der vorliegenden Erfindung ist. a ist ein Meßröhrchen, bei dem genau über dem Nullpunkt ein Hahn angebracht ist; dieser wird nach Durchtritt des Blutes geschlossen und schneidet die überstehende Blutsäule ab. b ist ein Meßröhrchen mit Überlaufgefäß. In Höhe des Nullpunktes befindet sich eine Öffnung, durch die das überflüssige Blut in das Gefäß abfließt. c ist ein Meßröhrchen mit Feststellring. Nach dem Verschieben des Röhrchens in dem Zylinder wi,rd rd die Kuppe der Blutsäule auf den Nullpunkt eingestellt und das Röhrchen in dieser Lage durch den Feststellring fixiert. Establishing the height of the column of blood can be done in several ways take place, which is not the subject of the present invention. a is a measuring tube, in which a cock is attached exactly above the zero point; this is after passage of the blood is closed and cuts off the protruding column of blood. b is a measuring tube with overflow vessel. At the level of the zero point there is an opening through which the excess blood drains into the vessel. c is a measuring tube with a locking ring. After the tube has been moved in the cylinder, the top of the blood column will appear set to zero and the tube in this position by the locking ring fixed.
