Description

Das Patent 898 366 betrifft ein Kolorimeter für grundverschiedene medizinische Untersuchungen, wie zur Feststellung des Hämoglobingehaltes und des Blutzuckerspiegeis. Sein Haupterfindungsmerkmal besteht darin, daß in dem Apparat mehr als ein Farbkeil, mindestens aber zwei Farbkeile vorgesehen sind, von welchen der eine für eine Untersuchungsart, der zweite für die andere dient, so daß der Arzt mit ein und demselben Apparat einmal den Hämoglobingehalt, das andere Mal den Blutzuckerspiegel bestimmen kann, indem er nacheinander den einen oder den anderen Farbkeil zur Feststellung der Farbtönung der Untersuchungsflüssigkeit verwendet. Patent 898,366 relates to a colorimeter for fundamentally different medical examinations, such as to determine the hemoglobin content and the Blood sugar level. Its main feature of the invention is that in the apparatus more than one color wedge, but at least two color wedges are provided, of which the one for one type of examination, the second for the other, so that the Doctor with one and the same device once the hemoglobin content, the other time Can determine blood sugar levels by looking at one or the other Color wedge used to determine the color of the test liquid.

Das Kennzeichen der Erfindung besteht darin, daß als Träger für die Farbkeile zur Ausführung der grundverschiedenen Untersuchungen eine einzige Glasscheibe dient, auf der mehrere, mindestens zwei Farbkeile nebeneinander angeordnet sind, wodurch sich ein gedrungener und einfacherer Aufbau des Apparates ergibt, der schnelle Untersuchungen zuläßt. The characteristic of the invention is that as a carrier for the Color wedges a single pane of glass to carry out the fundamentally different examinations serves, on which several, at least two color wedges are arranged next to each other, which results in a compact and simpler structure of the apparatus, the fast one Allows investigations.

Die Zeichnung stellt eine Ausführungsform der Erfindung dar. Im Gehäuses4 ist eine ringförmige GlasplatteB vorgesehen, deren Unterseite die beiden Farbkeile C1 und C2 trägt, während auf der Oberseite der Glasplatte eine aus Cellon bestehende Scheibe D sitzt, auf der entsprechende Skalen angebracht sind. Die Glasplatte B ist eingeklemmt, so daß durch Lösen der Schraube E die Skalenscheibe D bzw. die Glasplatte B verschoben werden kann. Die Glasplatte B ist durch den Eingriff des Ritzels G in das Zahnrad F durch das Handrad H verdrehbar, so daß durch Drehung der Glasplatte B der Farbgleichwert der zu untersuchenden Flüssigkeit festgestellt werden kann. The drawing shows an embodiment of the invention. In the housing4 an annular glass plate B is provided, the underside of which has the two colored wedges C1 and C2 carry, while on the top of the glass plate one made of cellon Disk D sits on the corresponding scales are attached. The glass plate B is clamped, so that by loosening the screw E, the dial D or the Glass plate B can be moved. The glass plate B is through the engagement of the Pinion G can be rotated into gear F by handwheel H, so that by rotation the color equivalent of the liquid to be examined was determined on the glass plate B can be.

Die an sich bekannte Optik besteht aus dem Außenrohr K, dem Innenrohrs mit der Okularfassung M und der darin befindlichen Linse N sowie aus dem mit dem Okular verbundenen Prisma. The optics known per se consists of the outer tube K, the inner tube with the eyepiece mount M and the lens N located in it, as well as from the with the Eyepiece connected prism.

Durch Verstellen des Okulars von oben nach unten kann das Prisma in zwei Stellungen gebracht werden. In der oberen Stellung betrachtet der Arzt den FarbkeilO, in der unteren Stellung den Farbkeil C2 mit der zu untersuchenden Flüssigkeit in den nebeneinander angeordneten Glasvierkantröhren 01 und 02, die gefedert im Gehäuse A gehalten werden. In der unteren Stellung des Okulars ist der Farbke,il C1 abgedeckt.By moving the eyepiece from top to bottom, the prism can be moved in two positions can be brought. In the upper position the doctor looks at the Color wedge O, in the lower position the color wedge C2 with the liquid to be examined in the juxtaposed glass square tubes 01 and 02, which are sprung in the Housing A are held. In the lower position of the eyepiece, the color key is il C1 covered.
