Abstract
Description
Technical Field
[0001] This utility model relates to the field of food safety testing technology, specifically to a test card for imazalil in food safety testing. Background Technology
[0002] The imazalil test card utilizes the principle of competitive immunochromatography. During the detection process, imazalil in the test solution binds to the gold-labeled antibody. This binding inhibits the binding of the gold-labeled antibody to the competing antigen detection line (T line) on the nitrocellulose membrane, thus affecting the color development of the detection line (T line). By observing the color development of the detection line (T line) and the control line (C line), the imazalil content in the sample can be determined. However, current imazalil test cards for food safety testing rely solely on the outer shell for pressure resistance, resulting in poor pressure resistance, easy damage, and short lifespan. Therefore, we propose a new imazalil test card for food safety testing. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide a prochloraz test card for food safety testing. By setting up an anti-pressure cover and anti-pressure components, the anti-pressure performance can be greatly improved without affecting the use of the prochloraz test card, resulting in a long service life. At the same time, by setting up an outer transparent film, it is easy to seal and avoids contamination of the nitrocellulose membrane by dirt.
[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:
[0005] A food safety testing card for imazalil includes:
[0006] The detection card body includes a housing and a top plate bonded to the top of the housing;
[0007] A pressure-resistant cover is inserted outside the main body of the detection card;
[0008] The pressure-resistant component includes a spring arranged inside the pressure-resistant cover, a fixing plate arranged at the bottom of the spring, and double-sided adhesive glued to the bottom end of the fixing plate and bonded to the top plate.
[0009] An outer transparent film is adhered to the top of the pressure shield, and a second sticker is adhered to the top of the outer transparent film.
[0010] As a preferred embodiment of the imazalil test card for food safety testing described in this utility model, the main body of the test card further includes a nitrocellulose membrane disposed inside the outer shell, a sample pad disposed at the top left of the nitrocellulose membrane, an absorbent pad disposed at the top right of the nitrocellulose membrane, and a control line and a test line disposed at the top of the nitrocellulose membrane.
[0011] In a preferred embodiment of the imazalil test card for food safety testing described in this utility model, an observation window and a sample dispensing port are sequentially provided at the top of the top plate.
[0012] In a preferred embodiment of the imazalil test card for food safety testing described in this utility model, the pressure-resistant cover has a hollow structure.
[0013] In a preferred embodiment of the imazalil test card for food safety testing described in this utility model, four pressure-resistant components are provided, and the four pressure-resistant components are distributed at the corners of the top of the top plate.
[0014] In a preferred embodiment of the imazalil test card for food safety testing described in this utility model, the length of the top surface of the outer transparent film is the same as that of the pressure-resistant cover.
[0015] As a preferred embodiment of the imazalil test card for food safety testing described in this utility model, it further includes an inner transparent film, which is adhered to the top of the top plate, and a first sticker is adhered to the top of the inner transparent film.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up an anti-pressure cover and anti-pressure components, the anti-pressure performance can be greatly improved without affecting the use of the imazalil test card, resulting in a longer service life. At the same time, by setting an outer transparent film, it is easy to seal and avoid contamination of the nitrocellulose membrane by dirt. In use, the user can directly align the anti-pressure cover with the top plate and insert it. During the insertion process, the double-sided adhesive of the anti-pressure components will stick to the top plate, thus fixing the anti-pressure cover and anti-pressure components. After fixing, due to the elasticity of the spring, the anti-pressure cover has a certain anti-pressure effect, which greatly improves the anti-pressure performance of the test card, prevents the test card from being crushed, and extends its service life. At the same time, the outer transparent film covering the anti-pressure cover forms a certain sealed space, which can prevent external dirt from contacting the nitrocellulose membrane.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0032] This utility model provides a prochloraz test card for food safety testing. By setting up an anti-pressure cover and anti-pressure components, the anti-pressure performance can be greatly improved without affecting the use of the prochloraz test card, resulting in a long service life. At the same time, by setting an outer transparent film, it is easy to seal and avoids contamination of the nitrocellulose membrane by dirt.
[0033] Figure 1-4 The diagram shown is an overall structural schematic of one embodiment of the imazalil test card for food safety testing according to this utility model. Please refer to [link / reference]. Figure 1-4 The main body of a food safety testing card for imazalil according to this embodiment includes: a card body 100, a pressure-resistant cover 200, a pressure-resistant component 300, and an outer transparent film 500.
[0034] Specifically, the main body 100 of the test card includes an outer shell 101 and a top plate 107 bonded to the top of the outer shell 101. The main body 100 of the test card also includes a nitrocellulose membrane 102 disposed inside the outer shell 101, a sample pad 103 disposed at the top left of the nitrocellulose membrane 102, an absorbent pad 104 disposed at the top right of the nitrocellulose membrane 102, a control line 105 and a test line 106 disposed at the top of the nitrocellulose membrane 102. In use, the sample pad 103 is used to receive the sample solution to be tested. The nitrocellulose membrane 102 is the core part of the test card. During the test, the gold-labeled antibody will bind to the analyte or competing antigen, thereby affecting the color development of the test line 106. The absorbent pad 104 is used to absorb excess sample solution to ensure the accuracy of the test results.
[0035] Furthermore, the top of the top plate 107 is provided with an observation window 108 and a sample dispensing port 109. During use, a sample can be added through the sample dispensing port 109, while the control line 105 and the detection line 106 can be observed through the observation window 108 to understand the test results.
[0036] Specifically, the pressure-resistant cover 200 is inserted outside the main body 100 of the test card. The pressure-resistant cover 200 has a hollow structure. When in use, the pressure-resistant cover 200 can protect the main body 100 of the test card and improve its pressure resistance.
[0037] Specifically, the pressure-resistant component 300 includes a spring 301 arranged inside the pressure-resistant cover 200, a fixing plate 302 arranged at the bottom of the spring 301, and double-sided adhesive 303 bonded to the bottom of the fixing plate 302 and bonded to the top plate 107. There are four pressure-resistant components 300, which are distributed at the corners of the top of the top plate 107. In use, the user can directly align the pressure-resistant cover 200 with the top plate 107 and insert it. During the insertion process, the double-sided adhesive 303 of the pressure-resistant component 300 will adhere to the top plate 107, thus fixing the pressure-resistant cover 200 and the pressure-resistant component 300. After fixing, because the spring 301 has a certain elasticity, the pressure-resistant cover 200 has a certain pressure resistance effect, which can greatly improve the pressure resistance of the test card, prevent the test card from being crushed, and extend its service life.
[0038] Specifically, the outer transparent film 500 is bonded to the top of the pressure-resistant cover 200, and a second sticker 501 is bonded to the top of the outer transparent film 500. The length of the top surface of the outer transparent film 500 is the same as that of the pressure-resistant cover 200. In use, the outer transparent film 500 can cover the pressure-resistant cover 200 to form a certain sealed space, which can prevent external dirt from contacting the nitrocellulose membrane 102. When tearing it open, the first sticker 401 can be pinched directly, and then force can be applied to drive the inner transparent film 400 away from the top plate 107 through the first sticker 401 for use.
[0039] Combination Figures 1-4 In this embodiment, a food safety testing card for imazalil is used. The user can directly align the pressure-resistant cover 200 with the top plate 107 and insert it. During insertion, the double-sided adhesive 303 of the pressure-resistant component 300 will adhere to the top plate 107, thus fixing the pressure-resistant cover 200 and the pressure-resistant component 300. After fixing, the spring 301 has a certain elasticity, giving the pressure-resistant cover 200 a certain pressure-resistant effect, which greatly improves the pressure resistance of the test card, preventing the test card from being crushed and extending its service life. Simultaneously, the outer transparent film 500 covers the pressure-resistant cover 200, forming a certain sealed space, which can prevent external contaminants from contacting the nitrocellulose membrane 102.
[0040] Specifically, it also includes an inner transparent film 400, which is adhered to the top of the top plate 107. A first sticker 401 is adhered to the top of the inner transparent film 400. In use, the inner transparent film 400 can cover the observation window 108 and the sample application port 109 of the top plate 107, which can prevent dirt from contaminating the nitrocellulose membrane 102 and the sample pad 103, thereby improving the accuracy of the inspection. When tearing it off, the first sticker 401 can be pinched directly and then force can be applied to pull the inner transparent film 400 away from the top plate 107 through the first sticker 401 for use.
[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
