Problems solved by technology

However, for a long time, the detection of colloidal gold test strips has mainly relied on visual inspection, that is, using human eyes to observe the color depth of the detection line on the colloidal gold test strips, which can only be qualitatively judged, and human factors have a great influence on the judgment of the test results, which is very difficult. It is easy to produce wrong inspection results. In addition, there are currently a few companies that use the reflection principle to detect colloidal gold test strips. Because the detection line on the paper strip is not a smooth surface, the accuracy of the measurement results using the specular reflection principle is also very high. Difference

specific Embodiment approach

[0024] Turn on the device, the main working interface of the instrument will be displayed on the LCD display 204, press the number key on the membrane keyboard, select the "detection" function in the main interface, and select the detection items for each detection channel in turn. If the project is used for the first time, the calibration operation will be performed automatically, and colloidal gold test strips of different concentrations are put in sequentially under the prompt of the LCD, and the device will automatically perform curve fitting and save the curve parameters for future detection.

[0025] After selecting the four detection channels, press "Enter" to confirm and enter the detection waiting interface. Drop the liquid to be tested on the colloidal gold test strip to be tested, and after the reaction time, stripes of different depths will be displayed at the positions of the detection line and the reference line. Put the colloidal gold test strip into the detecti...

Abstract

The invention relates to a multi-channel portable colloidal gold test paper strip quick test device, which mainly comprises a detector, wherein the detector comprises a detecting part, an electrical part and a software detecting part; the detecting part comprises a plurality of mutually independent detecting channels; the electrical part comprises an ARM data processor, a keyboard and an LCD; image data detected by the detecting part are processed and displayed by the electrical part; and the software detecting part controls detecting steps. The device has a multi-channel detecting structure, and four channels can carry out the same detection item as well as different detection items. The device has the advantages of high detection speed, large amount of samples and great practical value.

Description

technical field [0001] The invention relates to a detection instrument, in particular to a colloidal gold test strip detection instrument. Background technique [0002] As a new type of biochemical detection system, the biological test strip method has attracted more and more people's attention because of its convenient portability, simple operation, and fast determination speed, and it is playing an increasingly important role in on-site rapid detection. As a specific application of the biological test paper method, colloidal gold test strips have been widely used in food, water quality, medical and health and other fields. However, for a long time, the detection of colloidal gold test strips has mainly relied on visual inspection, that is, using human eyes to observe the color depth of the detection line on the colloidal gold test strips, which can only be qualitatively judged, and human factors have a great influence on the judgment of the test results, which is very diff...
