Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a clenbuterol detection card. Background Art

[0002] In existing food safety testing, a triple card is often required when testing meat. The "clenbuterol" in the sample combines with the specific monoclonal antibody labeled with colloidal gold during the flow process, inhibiting the binding of the antibody and the antigen conjugate on the NC membrane detection line.

[0003] For example Figure 5 As shown in the figure, if the content of the substance to be tested in the sample exceeds the detection limit, the test line will not show color, and the result is positive; otherwise, the test line will show red, and the result is negative. This test card is not only simple and fast, but also highly sensitive and has stable test results. It also does not require special testing equipment, and is very convenient to use, so it is widely used.

[0004] When dripping samples on the above-mentioned test card, it is necessary to control the amount of a single drop to avoid failure of the test card or affecting the interpretation results due to excessive sample addition. The existing sampling methods mostly use matching droppers or micropipettes to transfer such external instruments for collection, and there are many operating steps. Especially when conducting tests outdoors, it is very inconvenient to carry these external devices, making the collection work more cumbersome. Utility Model Content

[0005] Based on the above description, the utility model provides a clenbuterol detection card to solve the shortcomings of existing detection cards that require cooperation with external sampling instruments for detection, have many operating steps, and are very inconvenient to use, especially in outdoor detection.

[0006] The utility model is realized through the following technical solutions:

[0007] A clenbuterol detection card comprises a shell and a test strip, wherein the shell comprises an upper half shell and a lower half shell which are fixed to each other by clamping, a gap is left between the upper half shell and the lower half shell, and the upper half shell is also provided with a detection area and a dripping hole, the test strip is laid flat in the gap between the upper half shell and the lower half shell, and the lower half of the test strip is arranged just at the dripping hole, the upper half of the test strip is arranged at the detection area, and a sampling component is also provided inside the upper half shell between the detection area and the dripping hole and is connected to the dripping hole.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the detection zone and the dripping hole are arranged in three and spaced apart from each other, and the top surface of the detection zone is open and connected to the outside, and the dripping hole is a closed space built into the upper half shell.

[0023] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] Combination Figure 1-4 As shown, a clenbuterol detection card comprises:

[0026] The housing 1 is a plastic housing and is composed of an upper half shell 11 and a lower half shell 12. The upper half shell 11 and the lower half shell 12 are buckled with each other using a snap-fit ​​structure, so that a certain gap is left between the upper half shell 11 and the lower half shell 12.

[0027] Test strip 2 is a special test strip for detecting clenbuterol;

[0028] The sampling assembly 3 is arranged on the housing 1 and is mainly used for rapid quantitative sampling in conjunction with detection tests.

[0029] Specifically, the upper half shell 11 is also provided with a detection area 13 and a sample drop hole 14, wherein the detection area 13 is a rectangular opening groove and is arranged on the top surface of the upper half shell 11, and the detection area 13 is connected to the inside of the housing 1, and the upper half of the test strip 2 is just located at the rectangular opening groove;

[0030] The dripping hole 14 is a circular hole and is arranged inside the upper half shell 11. Its top surface is closed and the bottom is connected to the inside of the shell 1. The lower half of the test strip 2 is located exactly there and fits with the bottom of the dripping hole 14 to form a closed cylindrical space. The upper half shell 11 and the lower half shell 12 should strengthen the fitting strength around the dripping hole 14 to ensure its sealing effect.

[0031] There are less than three detection areas 13 and droplet holes 14, which correspond to three different detection functions, namely, the clenbuterol detection area 13, the ractopamine detection area 13 and the salbutamol detection area 13. Matching marks are arranged around the three detection areas 13 for quick identification by the staff.

[0032] The sampling assembly 3 includes an active cavity 31 arranged in the upper half shell 11 and located exactly between the detection area 13 and the dripping hole 14. An air bag 34 is provided in the active cavity 31. The air bag 34 extends to the inside of the dripping hole 14 through a hose 36 and is connected thereto. A collection tube 37 is also provided on the dripping hole 14. Three collection tubes 37 extend toward the bottom of the shell 1 and finally converge at one point and are connected to an infusion tube 38. The bottom end of the infusion tube 38 extends to the outside of the shell 1.

[0033] A pushing handle 33 is also provided in the movable cavity 31. Two pushing handles 33 are arranged on both sides of the airbag 34 respectively. A rubber pad is provided on the end surface of the inner end of the pushing handle 33. The rubber pad is tightly fitted and fixedly connected to the side wall of the airbag 34. The outer end of the pushing handle 33 is an arc block and has anti-slip texture on its surface.

[0034] In addition, in order to ensure that the pushing handle 33 can move smoothly in the active cavity 31 , a slide groove 32 should be provided on the inner wall of the active cavity 31 , and a protrusion is arranged on the side wall of the pushing handle 33 and matched with the slide groove 32 .

[0035] In the normal relaxed state, the outward end of the push handle 33 should always extend to the outside of the upper half shell 11, and the present embodiment relies on the extraction and relaxation of the airbag 34 for sampling, so the airbag 34 should also be deployed outward at all times, that is, a compression spring 35 is arranged inside the slide groove 32, one end of the compression spring 35 is fixed to the end face of the inner wall of the slide groove 32, and the other end is fixedly connected to the end face of the protrusion on the push handle 33, so when the end of the push handle 33 is pressed, the push handle 33 is squeezed inward, so that the airbag 34 is expanded. The internal space of the airbag 34 becomes smaller, and the air in the airbag 34 enters the three dripping holes 14 along the rubber tube 36, and is finally discharged through the collection tube 37 and the infusion tube 38; at this time, the pushing handle 33 is relaxed, and the compression spring 35 pushes the pushing handle 33 outward, and the internal space of the airbag 34 becomes larger, thereby forming an attraction force in the infusion tube 38 and the collection tube 37. If the infusion tube 38 is placed in the liquid to be tested at this time, part of the liquid to be tested will enter the three dripping holes 14 simultaneously, so that synchronous detection is performed relying on the three detection areas 13.

[0036] During the above sampling process, the internal space and shape of the airbag 34 should also be properly controlled to ensure the stability of the sampling amount for each single sampling, so as to avoid the failure of the test strip 2 due to excessive sampling, or the influence of too little sampling on the actual detection effect. By utilizing the above detection structure, the assistance of an external sampling instrument is no longer required, and it can be used with one hand. Moreover, the above components are made of common materials with relatively low production costs, which are more convenient for outdoor use and can effectively simplify the outdoor detection steps.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
