Vorrichtung zur Blutentnahme. Patentiert im Deutschen Reiche vom 23. April 1916 ab.Device for taking blood. Patented in the German Empire on April 23, 1916.
Die Erfindung bezieht sich auf einen Apparat zur Blutentnahme und Gewinnung sonstiger
Punktate zwecks bakteriologischer und serologischer Untersuchung.
Der Apparat besteht aus zwei Teilen, einem Aufstechapparat und einem Auffangbehälter
für das Punktat.The invention relates to an apparatus for taking blood and obtaining other punctures for the purpose of bacteriological and serological testing.
The device consists of two parts, a piercing device and a collecting container for the puncture.
Der Aufstechapparat wird dadurch gebildet, daß eine Punktionsnadel α beliebiger Länge undThe piercing apparatus is formed in that a puncture needle α of any length and

Die Platte ist wiederum mit einer Tülle d verbun-ίο strength is rigidly attached to a plate b made of any material. The needle protrudes any distance through the plate into the collecting container c. The plate is in turn connected to a grommet d

Dadurch wird erstens eine sicherere Führung der Punktionsnadel bei der Punktion erreicht, da durch die Verbindung zwischen Aufstech- und Auffangapparat eine handlichere Vorrichtung geschaffen wird, als wenn beide Teile gesondert gebraucht werden. Das Auffanggefäß wird durch diese Verbindung zum Handgriff.Firstly, this ensures that the puncture needle is guided more reliably during the puncture, because the connection between the piercing and collecting device makes it a more handy device is created as if both parts are used separately. The collecting vessel becomes a handle through this connection.
Es wird dadurch eine Hilfsperson bei der Punktion erspart. Zweitens wird durch die an der Tülle befestigte Platte der Auffangbehälter bei der Punktion geschlossen, so daß keine Luftkeime in den Behälter hineingelangen können. Dadurch wird eine bakteriologisch und serologisch einwandfreie ArbeitsmethodeThis saves an assistant during the puncture. Second, through the plate attached to the spout of the collecting container closed at the puncture, so that no airborne germs can get into the container. This makes a bacteriological one and serologically correct working method
; gewährleistet.; guaranteed.
Der Auffangbehälter für das Punktat, welcher aus einem Reagenzglas o. dgl. besteht, trägt an seiner Wandung zwei oder mehrere sich gegenüberstehende wulstförmige Eindrücke. Dieselben dienen dazu, den nicht verwendbaren Blutkuchen beim Ausgießen des aus dem Blute gewonnenen Blutserums festzuhalten. Durch das Festhalten des Blutkuchens wird eine Trübung des Blutserums vermieden. Rutscht nämlich der Blutkuchen beim Ausgießen des Serums an der glatten Wand des schräg nach abwärts gehaltenen Reagenzglases oder sonstigen Auffangbehälters mit nach abwärts, so lösen sich hierbei oder bei den sonstigen Bemühungen, den Blutkuchen auf andere Weise zurückzuhalten, rote Blutkörperchen aus demselben los und treten in das Blutserum über. Durch die dadurch verursachte Trübung wird die richtige Wertung der serologischen Untersuchungsresultate, z. B. der Wassermannschen Reaktion, in Frage gestellt.The collecting container for the punctured material, which consists of a test tube or the like, carries two or more opposing bulge-shaped impressions on its wall. The same serve to hold the unusable blood cake when pouring out the blood serum obtained from the blood. By holding on to the blood cake, clouding of the blood serum is avoided. If the blood cake slips on the smooth wall of the when pouring out the serum test tubes held diagonally downwards or other collecting container with downwards, in this way or in other efforts, the blood cake is loosened on others Way to withhold, red blood cells get rid of them and enter the blood serum above. The turbidity caused by this results in the correct evaluation of the serological Examination results, e.g. B. the Wassermann reaction.
Der ganze Apparat wird in der Weise gebraucht, daß man das Auffanggefäß mit einer Hand umfaßt und die auf ihm mittels Tülle und Platte befestigte Punktionsnadel in eine Ader oder sonstige Höhlung einsticht.The whole apparatus is used in such a way that the collecting vessel with a Hand embraces and the puncture needle attached to it by means of a spout and plate into a Punctures a vein or other cavity.
