Device for displaying detection result of specimen using visual sign

Abstract

The device comprises: a sample application zone, a reagent zone, a detection zone with positive and negative contrast zones and the combination zone for detected target, and a reagent strip. Wherein, the positive contrast zone comprises one or more material to show the first color on dried condition and the second color when on wet condition. If there is detected target in sample, the interactive action of the combination zone and contrast zone forms the legible symbols.

Description

technical field [0001] The invention belongs to medical diagnostic items, specifically a detection device that can quickly detect whether a sample contains an analyte. Background technique [0002] In any test, positive and negative control experiments are very important components. In immunological tests, these control tests are usually completed by combining immunological principles to form controls, and the results of control tests can be displayed as colored lines on the test strip. These types of control tests are effective in determining whether the detection device is functioning properly, but additional costs are incurred in the manufacture of this part of the device and in performing these control tests, especially as the specific binding molecules used in the control tests require very delicate techniques to be produced. In addition, these controlled trials can lead to misinterpretation of the test results by ordinary users without special training. Therefore, i...
