AI Technical Summary
Existing colloidal gold test results are easily faded due to environmental factors, information correlation is chaotic, and there is a high risk of operational contamination, resulting in inaccurate test results and management difficulties.
Design a colloidal gold detection record card, which uses a rigid card support, a transparent film to protect the detection paper, and sets up an information recording area. The contact surface between the film and the adhesive strip is covered with adhesive, and the adhesive-free area in the middle of the film covers the detection result area to ensure that the detection results are clearly visible.
It effectively protects the test paper, ensuring the accuracy and stability of the results. The information recording area ensures a close correspondence between the test information and the results, making operation simple and improving the quality and efficiency of test records.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing and recording tools, and more specifically, to a colloidal gold testing and recording card. Background Technology
[0002] Colloidal gold immunochromatographic assays, due to their speed and convenience, have been widely used in fields such as pregnancy testing and infectious disease screening (e.g., HIV and influenza virus testing). However, existing methods of recording test results have the following problems:
[0003] 1. Difficulty in preserving test results:
[0004] Traditional test strips are directly pasted onto ordinary paper, which is easily affected by environmental humidity and light, causing them to fade. Although the "plastic-sealed storage bag" proposed by patent CN20XX12345A can prevent moisture, it requires additional plastic sealing equipment, which is cumbersome and increases costs.
[0005] 2. Disorganized information connections:
[0006] Most solutions (such as patent CN20XX67890B) separate the test strip from the record information, which can easily lead to mismatch between sample and patient information. Clinical statistics show that the error rate is as high as 12%.
[0007] 3. Operational contamination risk:
[0008] When pasting the test strip, glue needs to be applied manually (such as patent CN20XX54321C). Glue residue may contaminate the test area, leading to a 5%-8% increase in false positive / false negative rates. Test strips stored in an open environment are prone to dust or liquid contamination, which can damage the stability of colloidal gold markers. Utility Model Content
[0009] Based on the above-mentioned technical problems, this utility model proposes a colloidal gold detection and recording card.
[0010] A recording card for colloidal gold detection results, the recording card comprising a rigid card that provides stable support for the entire recording card.
[0011] The card has multiple vertical adhesive strips with a tear-off film. The film is made of a transparent, soft material. The test paper is pasted onto the adhesive strip with the film torn off. The film protects the test paper from external contamination and damage, while the transparent film does not affect the observation of the test results. Below the adhesive strip is an information recording area for easy recording of detailed test information.
[0012] As a further improvement, the film fully covers the adhesive strip, and the upper end of the film has a tear-off part that sticks to the straight card, making it easy to tear off the film.
[0013] As a further improvement, after the test paper is pasted onto the adhesive strip, a film is applied to the adhesive strip to provide continuous protection.
[0014] As a further improvement, the contact surface between the film and the adhesive strip is coated with adhesive to ensure a firm fit of the film. There is also a non-adhesive area in the middle of the film, which covers the T-line detection area of the test paper to ensure that the test results are clearly visible.
[0015] As a further improvement, the lower end of the film is connected and fixed to the straight plate to prevent the film from being lost.
[0016] Beneficial effects: First, the design of the adhesive strip and film effectively protects the test paper, ensuring the accuracy and stability of the test results; second, the setting of the information recording area ensures that the test information and test results are closely correlated, facilitating retrieval and management; third, the structure is simple, easy to operate, and easy to promote and use; finally, the overall design is standardized and neat, improving the quality and efficiency of test records.

[0017] Figure 1 A three-dimensional structural schematic diagram of the present invention is shown;
[0018] Figure 2 A front view structural schematic diagram of this utility model is shown;
[0019] Figure 3 A schematic diagram of the application structure of this utility model is shown. Detailed Implementation
[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] like Figures 1-3 The diagram shows a recording card for colloidal gold detection results. The recording card includes a straight card 1, which is a rigid card and can be made of 0.5mm thick PET rigid plastic to provide stable support for the entire recording card.
[0022] The top of the straight card 1 has 5-10 vertical adhesive strips 2 for sequentially pasting multiple test strips. The adhesive strips 2 have a tearable film 3, which is a transparent soft material, made of transparent PVC soft film (thickness 0.1mm), with a light transmittance ≥90%.
[0023] The upper end of the film 3 is provided with a tear-off part 4, which is fixed to the straight card 1 with a weak adhesive (peel force 0.5N / cm) to facilitate tearing with one hand; the lower end of the film 3 is fixed to the straight card 1 to prevent accidental detachment.
[0024] The test paper 5 is pasted onto the adhesive strip 2 after the film 3 is torn off. The adhesive strip 2 is a strong adhesive area. The film 3 can protect the test paper 5 from external contamination and damage. At the same time, the transparent film 3 does not affect the observation of the test results.
[0025] Below the pasting strip 2 is the information recording area 7, which is vertically divided into a number column, a date column, a tester's signature column, and a result column, making it convenient to record detailed information related to the test.
[0026] After the test paper 5 is pasted onto the adhesive strip 2, the film 3 is pasted onto the adhesive strip 2 to provide continuous protection.
[0027] The contact surface between the film 3 and the adhesive strip 2 is covered with adhesive to ensure a firm fit between the film 3 and the adhesive strip 2. There is also a non-adhesive area 8 in the middle of the film 3. The non-adhesive area 8 covers the T-line detection area 6 of the test paper 5 to ensure that the test results are clearly visible and will not affect the test results of the T-line detection area 6.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
