[0002] The existing in vitro diagnostic reagent fluorescence test cards in the medical device industry are used in large quantities in hospitals. Hospital testing personnel need to use a large number of fluorescence test cards every day. When there are many patients, because the test lines and quality control lines contained in the fluorescence test cards are made of fluorescent materials and are invisible to the naked eye, it is very easy to miss patient samples, resulting in erroneous results and the possibility of patients missing treatment opportunities. Utility Model Content
[0003] The utility model provides a fluorescent test card. By setting an indicator line visible to the naked eye in a detection area corresponding to an observation window, the indicator line dissolves when in contact with a diluent and migrates chromatographically to a water absorption area. By observing whether the indicator line disappears, it can be determined whether a patient sample has been added, thereby effectively avoiding missing a patient sample and ensuring accurate test results.
[0004] In order to solve the above technical problems, the technical solutions of the present utility model are as follows:
[0005] The utility model provides a fluorescence test card, comprising:

[0007] a test line made of fluorescent material and invisible to the naked eye, the test line being located in the detection area and close to the sample addition area;
[0008] An indicator line visible to the naked eye, composed of Coomassie Brilliant Blue, is located in the detection area and is close to the water absorption area of the test paper. The indicator line dissolves upon contact with the diluent and migrates to the water absorption area through chromatography.
[0009] Optionally, the fluorescence test card further includes:
[0010] An indicator arrow is provided on the surface of the housing, and the indicator arrow is close to the sample addition hole.
[0011] Optionally, the fluorescence test card further includes:
[0012] An identification two-dimensional code is provided on the surface of the housing, and the identification two-dimensional code is located between the indicator arrow and the sample addition hole.
[0013] Optionally, a recessed cavity is provided on the surface of the shell, and the identification QR code is located on the bottom surface of the recessed cavity.
[0014] Optionally, the fluorescence test card further includes:
[0015] A sample number writing area is provided on the surface of the housing, and the sample number writing area is close to the observation window.
[0016] Optionally, two ends of the shell are respectively a square end and a circular end, the circular end is away from the sample addition hole, and the circular end serves as a handheld end.
[0017] Optionally, the circular end surface is provided with a groove.
[0018] Optionally, the inner bottom surface of the groove is formed with anti-slip grooves.
[0019] The above solution of the utility model includes at least the following beneficial effects:
[0020] The above-mentioned solution of the present invention sets an indicator line visible to the naked eye in the detection area corresponding to the observation window. The indicator line dissolves when it contacts the diluent and migrates to the water absorption area by chromatography.

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0028] like Figure 1-Figure 3 As shown, the utility model provides a fluorescence test card, comprising:
[0029] The test paper 2 is fixed inside the housing 1, the sample addition area 23 of the test paper 2 corresponds to the sample addition hole 13 on the surface of the housing 1, and the detection area 24 of the test paper 2 corresponds to the observation window 14 on the surface of the housing 1;
[0030] A test line 22 made of fluorescent material and invisible to the naked eye, located in the detection area 24 and close to the sample addition area 23;
[0031] The indicator line 21 is visible to the naked eye and is made of Coomassie Brilliant Blue. The indicator line 21 is located in the detection area 24 and is close to the water absorption area 25 of the test paper 2. The indicator line 21 dissolves when in contact with the diluent and migrates to the water absorption area 25 by chromatography.
[0032] In this embodiment, the sample and diluent are added through the sample addition hole 13, and the sample and diluent are chromatographically migrated to the detection area 24 through the sample addition area 23 of the test paper 2. When the indicator line 21 contacts the diluent, it dissolves and chromatographically migrates to the water absorption area 25. When no sample and diluent are added, the indicator line 21 is visible to the naked eye. After adding the sample and diluent for a period of time, the indicator line 21 disappears. Figure 4 As shown, by observing the state of the indicator line 21 of the detection area 24 through the observation window 14, it is possible to determine whether to add a patient sample, thereby effectively avoiding missing a patient sample and ensuring accurate detection results.
