Abstract

A test strip for use in clinical chemistry, in soil and water analysis, for chemical biological and physical investigations has an integrated filter for the photometric, reflection, photomeric, optical and visual measurement of clinical-chemical parameters. The carrier medium of the test strip is dyed thoroughly in a specific wavelength or is lined with a material of a specific wavelength. The reaction components for a water or solvent analysis are e.g. attached to the coloured carrier medium, with an integrated filter or coloured layer. The light source has a detector, sensor or photocells. A haemoglobulin determination demands e.g. a colour with a wavelength of 546mm. ADVANTAGE - This saves separately inserted filters so that filter mistakes are avoided and the large amt. needed for investment in filters is cut out.

Description

Die Erfindung betrifft einen Teststreifen, welcher aus einem mit Filtereigenschaften versehenen Trägermedium besteht, auf der die Reaktionskomponente oder Reaktionskomponenten angebracht sind. Ferner bestehen noch Möglichkeiten die Filterkomponente auf verschiedenste Art und Weise in das Reaktions-, Auswerte- und Vorrichtungssystem zu integrieren, wobei dieser Teststreifen zu klinisch-chemischen Untersuchungen verwandt, bzw. für andere analytische Aufgaben eingesetzt und visuell, optisch als auch photometrisch oder reflektionsphotometrisch ausgewertet werden kann. Die optische Auswertung kann z. B. mittels CCD Videokamera und entsprechendem Computer erfolgen! Die beinhaltete Filterkomponente ist dem jeweiligen Extintionsmaximum der Analyse nach Möglichkeit anzupassen! Bisher wurden die Teststreifen mittels einer Vergleichsskala verglichen, bzw. in ein Reflektionsphotometer überführt, wo dann unter Zuhilfenahme eines separaten Filters, bzw. mittels Monochromator die entsprechende Wellenlänge eingestellt wurde, um dann mittels Extinktionsmessung den Wert, der zu analysierenden Substanz bzw. Komponente ermittelt.The invention relates to a test strip consisting of a Carrier medium provided filter properties on which the Reaction component or components are attached. There are also options for the filter component various ways in the reaction, evaluation and Integrate device system, this test strip too related to clinical-chemical studies, or for others analytical tasks used and visual, visual as well can be evaluated photometrically or by reflection photometry can. The optical evaluation can, for. B. using a CCD video camera and appropriate computer! That included The filter component is the respective extinction maximum Adjust analysis if possible! So far, the Test strips compared using a comparison scale, or in transferred a reflection photometer, where then with the help a separate filter, or by means of a monochromator appropriate wavelength was set, then using Absorbance measurement the value of the substance to be analyzed or Component determined.

Hierbei mußte gerätemäßig eine bestimmte Wellenlänge eingestellt werden, bzw. von Hand ein bestimmter Filter in das Gerät geschoben oder dort justiert werden. Hierzu mußte der Verwender bzw. Analysator stets den entsprechenden Filter zur Hand haben, bzw. käuflich erwerben. Dieses Prinzip nun entscheidend zu ver­ einfachen war die gestellte Aufgabe und die Investitionssumme, die durch die unzähligen Filter erheblich war, entsprechend zu verringern.Here, a certain wavelength had to be set by the device a certain filter into the device by hand pushed or adjusted there. The user had to do this always have the appropriate filter on hand, or purchase them. This principle is now crucial to ver the task was simple and the amount invested, which was significant due to the countless filters reduce.

Durch Integrierung der Filterkomponente in den Teststreifen ist es gelungen, auf die Verwendung weiterer Filter gerätemäßig zu verzichten, so daß das Gerät lediglich eine Lichtquelle mit ent­ sprechenden Photozellen oder Sensoren benötigt. Die Teststreifen können dadurch auch so konzipiert werden, daß sie aus verschiede­ nen Filterabschnitten bestehen, so daß eine gleichzeitige Analyse entsprechend eines bestimmten Profiles durchgeführt werden kann. Hierbei wird eine exaktere Steuerung im Extinktionsmaximum des Reaktionskomponentensystems erzielt und ist somit zur Analyse sofort einsetzbar.By integrating the filter component into the test strip succeeded in using additional filters do without, so that the device only has a light source with ent speaking photocells or sensors. The test strips can also be designed so that they from different NEN filter sections exist, so that a simultaneous analysis can be carried out according to a certain profile. Here a more precise control in the extinction maximum of Reaction component system achieved and is therefore for analysis immediately usable.
