The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present invention and should not be construed as limiting the present invention, and all other embodiments that can be obtained by one skilled in the art based on the embodiments of the present invention without inventive efforts shall fall within the scope of protection of the present invention.

In order to solve the above technical problems, as shown in fig. 1 and 3, the present invention provides a test strip 100, where the test strip 100 includes a test strip substrate 110, and a detection area 130, an environmental imprinting area 140, and a password area 120 disposed on the test strip substrate 110, where the detection area 130 includes a detection reagent for generating a chemical reaction with a sample and displaying the chemical reaction; the environment mark area 140 is used for marking environment information during detection; the code region 120 is used to mark the code to identify the test paper.

In this embodiment, the test paper substrate 110 may be made of common test paper materials such as cotton fibers or PET materials with better toughness, the detection area 130, the environmental imprinting area 140, and the password area 120 are used as three different areas on the test paper substrate 110, the used materials are different, in order to avoid mutual interference between the areas, two adjacent areas may be separated by a certain distance, and a waterproof material 160 (such as Polyvinyl chloride, PVC, etc.) is disposed in the separated distance to separate the areas.

The detection area 130 is used for detecting whether a certain substance exists in a sample through a chemical reaction so as to perform qualitative detection and quantitative detection on the substance, for example, a test paper which uses a mixed solution of horseradish peroxidase, a color developing agent, a protease protective agent and water as a detection reagent is used for detecting the content of hydrogen peroxide in food; the AIDS virus test paper utilizes the activity of alkaline phosphatase or horseradish peroxidase marked by antigen-antibody to determine the antigen-antibody complex, thereby judging whether the blood or body fluid of a tester contains the anti-HIV antibody; the early pregnancy test paper utilizes a double antibody sandwich method to detect HCG value in urine and the like. The environment mark area 140 is used for marking the environment information in the area, and a user (the user refers to a person who marks each area, hereinafter, "detected person" also appears, and refers to a person who provides a sample) can directly mark the environment information collected by an external tool in the environment mark area 140, for example, the environment temperature, humidity, time and weather state obtained on a mobile phone are respectively marked at a specific position of the environment mark area 140 by specific marks (such as numbers and patterns), and at this time, the environment mark area 140 is only used as an area for displaying the marks; this environmental seal of government organization in old china district 140 also can directly adopt specific material to test information such as ambient temperature, humidity, weather condition to show with specific mode by oneself, if adopt humidity response membrane to gather ambient humidity, the corresponding sign such as "cloud", "rain", "sun" that shows of different humidity results, environmental seal of government organization in old china district 140 has two functions of detection and demonstration this moment. The password region 120 serves to mark a code, which may be randomly selected by a user or calculated by a specific algorithm based on the detection result of the detection region 130 and the display result of the environmental stamp region 140, and is intended to ultimately give the test strip an identity to help the user identify the test strip. In the event that some users do not wish to read the code by the subject, the code region 120 may be made of a particular material, such as a light sensitive material, that is illuminated with light of a particular wavelength to be displayed, or the code may be marked in a particular manner on the code region 120, such as by writing with a black light pen, by being illuminated with ultraviolet light, etc.

The user marks the environmental information through the environmental seal district 140 earlier, further marks the code in password district 120, gives the person who is examined test paper 100 again to carry out sample collection and detection, and the person who is examined will have the test paper 100 of sample at detection district 130 and hand over the user, accomplishes whole testing process. In the present embodiment, the environmental stamp area 140 and the password area 120 are used to multiply mark the test strip 100, so that the test strip 100 cannot be exchanged by the testee during the testing process. Moreover, since the obtained environment information under different environments is different, and the generation of the code marked by the code area 120 is unique, that is, each test strip 100 has no specific identity before use but a temporarily determined identity during use, so that the test strip has irreplaceability, and the test strip cannot be falsely used. Aiming at other scenes in ordinary life, such as detection of some diseases and detection of some elements in the body, the test paper 100 is also applicable, and detection results carried out at different periods are distinguished by environmental information and codes, so that a user can conveniently know the change of the health state of the body by contrasting the detection results.

In a preferred embodiment, as shown in FIGS. 2 and 3, the detection zone 130 includes a first detection zone 131 and a second detection zone 132, where the first detection zone 131 and the second detection zone 132 have different detection reagents or have different detection reagent concentrations.

In this embodiment, the first detection area 131 and the second detection area 132 use different detection reagents, the two different detection reagents detect the same substance, the sample reacts with the two detection reagents to generate different chemical reactions, and the detection result of the two detection reagents is compared to obtain a more accurate detection result of whether the detected substance exists.

Further, since the test strips having different detection reagent concentrations have a limited range of the concentration of the test substance that can be detected, the test strips having different detection reagent concentrations have different sensitivities for detecting the concentration of the test substance in the sample. In the embodiment, the same detection reagents with different concentrations are used in the first detection area 131 and the second detection area 132 to detect the same substance in the same sample, and the two detection results are compared with each other, so that the concentration of the substance to be detected in the sample can be more accurately calculated, and the accuracy of quantitative detection can be improved. For different body fluids of the same subject, the concentrations of the substances to be detected may be different, and therefore, the two detection regions 130 with different concentrations of the detection reagent are respectively used for detecting, for example, the first detection region 131 is used for detecting saliva, the second detection region 132 is used for detecting urine, and the result of the determination of the certainty that whether the substance to be detected exists in the subject is more reliable under the comprehensive determination of the two detection results.

In a preferred embodiment, as shown in FIG. 3, the detection surfaces of the first detection area 131 and the second detection area 132 have a height difference.

In this embodiment, since the first detection area 131 and the second detection area 132 have different concentrations of the detection reagent, the generated chemical reaction results are different, the first detection area 131 and the second detection area 132 are configured in a staggered manner with different heights, so that the mutual interference between the detection results of the two detection areas 130 can be avoided, and the height difference between the detection surfaces of the two detection areas 130 is preferably 2 mm. In addition, the first detection zone 131 and the second detection zone 132 are preferably spaced apart from each other and are preferably separated by a water-resistant material 160.

In a preferred embodiment, as shown in fig. 2, the test strip 100 further includes an identity mark area 150, the identity mark area 150 is used for marking a first code generated according to the environmental information displayed by the environmental stamp area 140 and the detection result displayed by the first detection area 131, and the password area 120 is used for marking a second code generated according to the first code displayed by the identity mark area 150 and the detection result displayed by the second detection area 132.

In this embodiment, the identity mark area 150 is used to generate a first code uniquely corresponding to the identity of the detected person, and the first code is obtained according to the environment information of the environment stamp area 140 and the detection result of the first detection area 131 according to a specific algorithm, specifically: the environmental information marked by the environmental stamp area 140 is directly presented in a digital form or different special marks (such as "cloud", "rain" and "sun") respectively correspond to specific numbers, the detection result of the first detection area 131 scans the color change of the area through the intelligent terminal and outputs the concentration of the detected substance, the concentration is represented in a digital form, the number corresponding to the environmental information and the number corresponding to the detection result respectively take last mantissa (or all the numbers are multiplied and take the last several digits), and the combination of the last mantissa is the first code. Similarly, the second code of the code region 120 is a combination of the last number of the concentration of the test substance corresponding to the detection result of the second detection region 132 and the last mantissa of the first code, and constitutes the second code.

The embodiment is particularly suitable for the situation that the person to be detected needs to leave the supervision and complete two detections (for example, in a drug-related case, privacy-related urine detection is involved, the test strip 100 needs the person to be detected to provide saliva as a first sample, and urine as a second sample). First, a supervisor (i.e. the user mentioned above, which is used to mark each area correspondingly and plays a role of supervising the tested person to complete sample collection) takes out one piece of test paper 100, marks environment information (automatically displayed image or color, or digitized environment information obtained by the intelligent terminal according to the displayed image or color) in the environment mark area 140 correspondingly, marks the environment mark area 140 manually, drops a first sample from the tested person in the first detection area 131, generates a first detection result after a certain time, generates a first code according to the first detection result and the environment information by the supervisor (self-calculation or calculation through the intelligent terminal), and marks the first code in the identity mark area 150 by the supervisor. Another piece of test paper 100 is taken, the environmental information and the first code are marked in the designated area of the second piece of test paper 100, the second piece of test paper 100 is handed to the detected person, the detected person drops the second sample into the second detection area 132 of the second piece of test paper 100 after leaving the supervisor to generate a second detection result, and the supervisor generates a second code according to the second detection result and the first code and marks the second code area 120 of the second piece of test paper 100, so that the whole detection process is completed. After the detection is finished, the two test strips 100 are compared, the second codes of the two test strips are consistent with the detection result, if the second codes are inconsistent, the second test strip 100 is exchanged, and if the second codes are consistent but the second detection result is obviously inconsistent with the first detection result, the second sample on the second test strip 100 is not provided by the detector, and a counterfeit behavior exists in the second detection process.

In a preferred embodiment, as shown in fig. 2, the environmental imprint area 140 includes a timing imprint area 141 and a positioning imprint area 142, the timing imprint area 141 is used for recording the detection time, and the positioning imprint area 142 is made of a humidity-sensitive material for collecting and marking the environmental humidity during detection.

In this embodiment, the timing mark area 141 may be made of a paper material capable of handwriting time, or may be made of a photosensitive material, and a time mark is printed on the surface of the photosensitive material by special light irradiation, so as to record the time for detecting the sample. The positioning mark area 142 is used for marking the humidity of the external environment where the test strip 100 is located, the humidity changes by absorbing the moisture in the environment after the humidity-sensitive material is exposed in the air for a certain time (e.g., 30 seconds), and a humidity comparison table is used in cooperation with the humidity-sensitive material, so that a user can compare the color displayed by the humidity-sensitive material with the color of the humidity comparison table and read the humidity of the environment. The color that the humidity sensitive material shows still can carry out the accuracy through intelligent terminal and read, and intelligent terminal has stored the humidity reference list, compares in order to read environment humidity through the color that the humidity sensitive material shows and the color of humidity reference list equally, and the result that intelligent terminal read compares the naked eye and reads more accurately. The humidity sensitive material can adopt a polyvinylidene fluoride/hydroxyethyl cellulose blend, a humidity sensitive film made of modified polyimide, a graphene oxide film and the like.

The embodiment adopts the timing mark area 141 and the positioning mark area 142 to mark the environmental information, so as to better record the environment of the test strip 100 when being used and prevent the test strip from being exchanged. Meanwhile, when the detection result of the detection test strip 100 is analyzed, the environmental information may also be used as a reference factor, for example, in the morning and afternoon, the concentration of a substance in a body fluid (or blood) of a subject may change, different environmental humidities may have an influence on the detection area 130 of the test strip, and the like, and the reference factor is listed in the analysis of the detection result, which may help to obtain a more accurate detection and analysis result.

Further, the timing mark area 141 includes a photosensitive area sequentially corresponding to ten digits of 0 to 9, and the photosensitive area is discolored by light of a designated wavelength.

Photochromic materials such as azobenzenes, spiropyrans, spirooxazines, fulgides, naphthonaphthoquinones, dithizones, diarylethenes and the like are used for the photosensitive region (excluding digital printing materials therein). A light-sensitive area correspondingly contains a number, and when the user needs to mark the detection time on the test strip 100, a light source (e.g. near-uv) with a specific wavelength can be used, corresponding to the target number corresponding to the current time, for example: two and thirty minutes in the afternoon correspond to 0, 2, 3, 0 four light sensitive areas (to reduce the numerical repetition rate, the time is preferably recorded at 12 o' clock, also preferably exactly to half an hour, i.e. the last two digits are always 00 or 30; if necessary, am, pm two light sensitive areas can be added to indicate am and pm respectively), and a preset time, for example 10 seconds, is illuminated for changing the color of the illuminated light sensitive areas, thus forming a record of the time. For another example, two numbers in 11:00 are repeated, corresponding to two photosensitive regions of 1 and 0, two numbers in 11:30 are repeated, corresponding to three photosensitive regions of 1, 3 and 0, and the repeated numbers can be changed into specific colors by adopting light rays with different intensities, for example, the number used once is blue, the number repeated twice is purple, the number repeated three times is black, and the like, in this case, the photosensitive regions can be prepared by adopting a structure comprising polyurethane and a core-shell structure WO₃-photochromic paint composed of Ag nano material.

Under some conditions, a user does not want the recorded time to know by others, the photosensitive area can adopt reversible light-variable anti-counterfeiting ink, the chemical substance A in the photosensitive area is converted into a chemical substance B under a certain illumination condition, the first color of the photosensitive area is converted into a second color different from the first color, the chemical substance B reversely generates the chemical substance A after the photosensitive area is irradiated or heated by a light source with another wavelength, the second color of the photosensitive area is recovered into the first color, and others cannot know that the photosensitive area is marked; when the recorded time needs to be read, the photosensitive area is irradiated again under the original illumination condition, so that the marked photosensitive area can display a second color different from other unmarked photosensitive areas which are displayed as the first color, and the detection time of the mark can be obtained.

The invention also provides a use method of the test paper, as shown in fig. 4, the use method comprises the following steps:

step S10: the environment information is marked in the environment print area 140.

The environmental information includes temperature, humidity, weather, time, geographical location, etc. the user optionally selects at least one environmental information, which is marked in the environmental mark area 140 in a graphic, text or numerical form as a mark of the environment of the test strip 100 at the time of use. The environmental information is not limited to be collected through the detection test paper 100, and can be obtained through observation of a user and detection of intelligent equipment, for example, humidity information can be obtained by adopting a humidity-sensitive material, temperature information can be directly obtained through an intelligent bracelet, weather and time can be obtained through observation, and a geographic position can be obtained through equipment such as the intelligent bracelet or a mobile phone with a positioning function.

Step S20: the sample is added to the detection zone 130.

Each test strip 100 may include a single detection zone 130 or a first detection zone 131 and a second detection zone 132 having different detection reagent concentrations, in which case, the same kind of sample of the same subject may be added to the two detection zones 130, respectively, and the mobile terminal is used to acquire the color change of the two detection zones 130, so as to perform the content of the substance to be detected in the sample. In the process, even if the detected person is out of the monitoring range, the comparison of the detection results of the two detection regions 130 can be used to judge whether the samples in the two detection regions 130 are from the same detected person, so as to prevent the situation of exchanging the detection samples.

Step S30: after the detection area 130 generates a detection result, a code is obtained according to the environment information and the detection result according to a preset condition, and the code is marked to the password area 120.

The preset conditions in this step may be: the detection result and the environment information are mixed and coded to form a special figure, number or character-shaped code; or, the detection result and the environment information are expressed as numbers, and then the two numbers are combined or added, multiplied, etc. to operate according to a specific formula, or some numbers are taken to operate or combine, etc. to form a code, which can be hand-written to the code area 120, or through the method of hand-writing to the code area 120, or through the method of

In this embodiment, the user marks the environmental information through the environmental mark area 140, and then gives the test paper 100 to the detected person for sample collection and detection, and the detected person returns the test paper 100 with the sample dropped on the detection area 130 to the user, and after the user marks the code generated by combining the detection result and the environmental information to the password area 120, the whole detection process is completed. The user uses the environmental mark area 140 and the password area 120 to perform multiple labeling on the test strip 100, so that the test strip 100 cannot be exchanged by the subject during the test. Moreover, because the obtained environment information under different environments is different, and the generation of the code marked by the code area 120 is unique, that is, each test strip 100 has no specific identity before use but a temporarily determined identity during use, so that the test strip has irreplaceability, and a person to be detected cannot falsely use the test strip. Aiming at other scenes in ordinary life, such as detection of some diseases and detection of some elements in the body, the test paper 100 is also applicable, and detection results carried out at different periods are distinguished by environmental information and codes, so that a user can conveniently know the change of the health state of the body by contrasting the detection results.

In a preferred embodiment, as shown in fig. 5, the step S10 includes:

step S11: the positioning print zone 142 in the environmental print zone 140 is exposed to air for a preset time.

In the foregoing embodiment, the environmental imprint area 140 includes the positioning imprint area 142 and the timing imprint area 141, wherein the positioning imprint area 142 uses the humidity-sensitive material, and the timing imprint area 141 uses ten photosensitive areas corresponding to ten numbers of 0 to 9. In this step, the positioning mark area 142 can show a significant color change after being exposed in the air for about 30 seconds, and the current ambient humidity can be determined according to the color change.

Step S12: the photosensitive area in the environmental print area 140 corresponding to the current time is selected according to the current time.

Step S13: the photosensitive area is continuously irradiated with light of a specific wavelength until the photosensitive area is discolored.

In this step, the timing mark area 141 includes ten photosensitive areas, each of which is correspondingly marked with a number, for a total of ten numbers from 0 to 9. When the user needs to mark the detection time on the time stamp area 141, a light source (e.g. near ultraviolet) with a specific wavelength can be used to correspond to the target number corresponding to the current time, for example: two and thirty minutes in the afternoon correspond to 0, 2, 3, 0 four light sensitive areas (to reduce the numerical repetition rate, the time is preferably recorded at 12 o' clock, also preferably exactly to half an hour, i.e. the last two digits are always 00 or 30; if necessary, am, pm two light sensitive areas can be added to indicate am and pm respectively), and a preset time, for example 10 seconds, is illuminated for changing the color of the illuminated light sensitive areas, thus forming a record of the time. For another example, two numbers in 11:00 are repeated, corresponding to two photosensitive regions of 1 and 0, two numbers in 11:30 are repeated, corresponding to three photosensitive regions of 1, 3 and 0, and the repeated numbers can be changed into specific colors by adopting light rays with different intensities, for example, the number used once is blue, the number repeated twice is purple, the number repeated three times is black, and the like, in this case, the photosensitive regions can be prepared by adopting a structure comprising polyurethane and a core-shell structure WO₃-photochromic paint composed of Ag nano material.

After the above steps are finished, a step can be further performed: the test strip 100 is placed in a dark environment until the light sensitive area recovers its pre-illuminated color.

In the step, a photosensitive area adopts reversible light-variable anti-counterfeiting ink, a chemical substance A (such as a closed-loop compound) in the photosensitive area is converted into a chemical substance B (such as an open-loop compound) under a certain illumination condition (such as near ultraviolet rays), the photosensitive area is changed from colorless to color development, the chemical substance B reversely generates the chemical substance A after being placed in a dark environment for a certain time, the color development of the photosensitive area is recovered to be colorless, and other people cannot know that the photosensitive area is marked; when the recorded time needs to be read, the photosensitive area is irradiated again under the original illumination condition (near ultraviolet), so that the marked photosensitive area can be developed again, and the detection time of the mark can be obtained.

In a preferred embodiment, as shown in fig. 6, the step S30 includes:

step S31: and scanning the color of the positioning print area 142 by using the intelligent terminal and correspondingly generating a first digital code.

The intelligent terminal is pre-stored with a comparison table of different colors corresponding to different numbers, and humidity data, namely a first digital code, can be automatically obtained after the displayed color of the positioning imprinting area 142 is obtained by scanning.

Step S32: and scanning the time stamp area by using an intelligent terminal and acquiring the corresponding number of the color-changed photosensitive area to form a second digital code.

step S34: and generating codes according to a preset algorithm by the first digital code, the second digital code and the third digital code, and marking the codes to the password area 120.
