Description

Gegenstand der Erfindung ist ein Farbkeil zur kolorimetrischèn Blutzlickeruntersuchunlg. The subject of the invention is a color wedge for the colorimetric blood leakage investigation.

Es ist bekannt, den Blutzuckergehalt des menschlichen Blutes auf Grund der Reaktion mit alkalischer Pikrinsäure zu bestimmen. Die Blutprobe wird nach Behandl-ung mit alkalischer Pikrinsäure in einem Kolorimeter mit einem Faribkeil verglichen. Für eine exakte Messung muß der Meßkeil oder das Meßfilter die gleiche oder ähnliche Absorptionskurve haben wie die bei der genannten Reaktion entstehende Färbung der -Blutprobe. It is known to increase the sugar levels of human blood Determine the reason for the reaction with alkaline picric acid. The blood sample will after treatment with alkaline picric acid in a colorimeter with a colored wedge compared. For an exact measurement, the measuring wedge or the measuring filter must be the same or have an absorption curve similar to that resulting from the reaction mentioned Staining of the blood sample.

Es wurde gefunden, daß sich hierzu am besten Keile, vorzugsweise Gelatinekeile eignen, deren Gußlösung die gleiche Substanz enthält, die bei dieser Reaktion entsteht. Gemäß der Erfindung wird daher in einer Einrichtung zur Bestimmung des Blutzuckers ein Farbkeil verwendet, dessen Gußlösung Pikraminsäure zugefügt ist. It has been found that this is best done with wedges, preferably Gelatine wedges are suitable, the casting solution of which contains the same substance as this one Reaction arises. According to the invention, therefore, in a device for determining of blood sugar a colored wedge is used, the casting solution of which is added picric acid is.

Eine bevorzugte Zusammensetzung der Gußlösung ist foligenlde: In einem Liter Farbstofflösung in destilliertem Wasser sind I,3 g Pikraminsäure, 2,5 g Natriumhydroxyd, o,57g Pelikan-Perltusche (chinesische Tusche) enthalten. Diese Lösung wird zum Vergießen mit Gelatinelösuneg vermischt. A preferred composition of the casting solution is foligenlde: In one liter of dye solution in distilled water is 1.3 g of picric acid, 2.5 g sodium hydroxide, 0.57 g pelican pearl ink (Chinese ink). These Solution is mixed with gelatin solution for pouring.

Die Absorptionskurve einer solchen Gußlösung ist in der Zeichnung dargestellt. Der Vorteil eines solchen Filters besteht darin, daß die Genauigkeit der Messung unabhängig von der Farlbe des verwendeten Lichtes ist. The absorption curve of such a casting solution is in the drawing shown. The advantage of such a filter is that the accuracy the measurement is independent of the color of the light used.
