Problems solved by technology

[0006] Thirdly, if the traditional test strip is photographed and scanned by a mobile phone, it is easily affected by the surrounding lighting environment (such as light intensity and light source color changes), resulting in color difference, which affects the accuracy of the test results

Embodiment 1

[0083] Such as figure 1 As shown, the picture above is a schematic diagram of the front of the new test strip, and the labels on the illustration include:

[0084] 1 Substrate

[0085] 2 barcode fields

[0086] 3 Detect color block area

[0087] 4 standard color block area

[0088] 5 detection blocks

Embodiment 2

[0090] Such as figure 2 As shown, it is a traditional detection test strip. The length of the sheet depends on the item to be inspected. Usually not more than 150mm. The width of the test strip is 5-10mm.

[0091] There can be 1-18 test items on a test strip. figure 2 Each small color block in corresponds to a detection item. There is an interval of 2-4mm between the color blocks, the main purpose is to prevent the liquid after detection from penetrating each other and causing color block pollution, causing detection errors.

[0092] The main principle of the detection test strip includes the colorimetric detection of chemical reaction based on the dry chemical test paper detection method, and the judgment of the color band (whether the detection line and the quality control line are colored) based on the immunochromatography method.

[0093] Manufacturing method:

[0094] The preparation method of the traditional detection test strip is to do longitudinal gluing and s...

Embodiment 3

[0102] First, the following introduces the production process of test strips

[0103] Raw material 1 is substrate 1, such as image 3 , can be printed, and the grid lines in the middle do not exist in the real thing (it is a design drawing). The size of the substrate will be fabricated as required.

[0104] Raw material two is a test strip containing reactive chemicals such as Figure 4 As shown, each color bar contains different chemical reagents, which can react with the corresponding detection substances. Explanation: This color block bar is straight, similar to the image below. The test board is matched with the substrate 1 .

[0105] The processing steps of test strips are as follows:

[0106] Step 1: Print barcode area 2 on substrate 1, such as Figure 5 shown. The barcode information includes the model of the test strip, the authenticity and the cis-reversal of the strip, which can be identified by scanning the barcode with the mobile app.

[0107] Step 2: Paint...

Abstract

The invention provides a novel test paper strip as well as preparation and application of the novel test paper strip. The preparation comprises the following steps: A, preparing a base plate with the corresponding size; B, coating the base plate with a test paper plate which is matched with the base plate and contains reaction chemicals; C, printing bar codes on the base plate, wherein information of the bar codes comprises the modes of the test paper strips, true and false information, and the cis-trans states of the strips; and judging the cis-trans states by scanning the bar codes by a phone App; D, coloring the base plate, wherein the colors are colors with the standard values; E, cutting the test paper plate along small square blocks coated with glue, wherein only the test paper plate is cut and the base plate is not cut; and rotating and blowing off the test paper plate which is not coated with the glue by wind; and F, cutting the base plate along lines among the bar codes so as to obtain the test paper strip. By adopting the scheme, the accuracy that an intelligent phone directly scan and read color data can be improved greatly, so that the practicability of phone applications can meet the detection requirements.

Description

technical field [0001] The invention relates to the medical field, in particular to a novel detection test strip and its preparation and application. Background technique [0002] The test strip that judges the test result according to the color change is a kind of widely used rapid detection tool, which can be used for routine physical and chemical index detection, biochemical index detection, etc. Its technical principles include but are not limited to dry chemistry, immunochromatography (based on colored latex particles), chemiluminescence, etc. The tester can judge and obtain the test result according to the color change after one or more test blocks on the test strip interact with the sample to be tested. For example, users can carry out qualitative detection through item-by-item comparison with the naked eye, and can judge whether the test results on the test strip are negative or positive; they can also use special instruments to conduct semi-quantitative or quantita...
