Description

Technical Field

[0001] The utility model relates to the technical field of test strips, in particular to a fluorescent microsphere test strip. Background Art

[0002] Fluorescent microspheres refer to solid particles with diameters ranging from nanometers to micrometers, loaded with fluorescent substances, and capable of emitting fluorescence when stimulated by external energy. They can be in any shape, with a typical shape being spherical. The carriers of fluorescent microspheres are mostly organic or quinazoline polymer materials, which have relatively stable morphological structures and luminescent behaviors, and are less affected by external conditions such as solvents, heat, electricity, and magnetism than pure fluorescent compounds. As a new type of carrier material, they have been widely used in the biomedical field.

[0003] For example, Chinese patent application No. 202022738190.0 relates to a fluorescent microsphere test strip and a test strip box, which includes a test strip body, wherein the test strip body includes a bottom plate, a sample pad fixedly arranged on the bottom plate, a detection pad fixedly arranged at one end of the sample pad on the bottom plate, an absorption pad fixedly connected to the end of the detection pad away from the sample pad, and a connecting pad fixedly arranged on the bottom plate, wherein the connecting pad is fixedly connected to the sample pad and the detection pad and is located between the two, and the absorption pad is fixedly arranged on the bottom plate; a quality inspection line and a detection line are arranged on a side wall of the detection pad away from the bottom plate. The present application has the advantages of simple operation, time-saving and labor-saving, and is conducive to improving the work efficiency of the staff;

[0004] In the above scheme, there is only one test strip in a box. In order to increase the accuracy of the data, a second test is often performed. It takes a while to wait for the results to appear, which reduces the work efficiency. In order to solve the above problems, we designed a fluorescent microsphere test strip. Utility Model Content

[0005] The utility model provides a fluorescent microsphere test strip to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fluorescent microsphere test strip comprises two bottom plates, the side walls between the two bottom plates are fixedly connected with a folded portion, the two bottom plates are provided with a sample pad, a connection pad, a detection pad and a water absorbent pad, the sample pad, the connection pad, the detection pad and the water absorbent pad are all fixedly connected to the upper side wall of the bottom plates, the opposite ends of the sample pad and the detection pad are both fixedly connected to the upper side wall of the connection pad, one end of the water absorbent pad is fixedly connected to the upper side wall of the detection pad, and the end of the detection pad away from the connection pad is provided with a quality inspection line and a detection line.

[0008] As a further improvement of the technical solution: the upper side walls of the two bottom plates are both provided with pressure-sensitive adhesives, and isolation paper is provided on the two pressure-sensitive adhesives, and the cross-sections of the two pressure-sensitive adhesives are relatively concave.

[0009] As a further improvement of the technical solution: a hand pad is fixedly connected to the bottom side wall of one of the bottom plates.

[0010] As a further improvement of the technical solution: the sample pad, the connection pad, the detection pad and the water absorption pad are all bonded to the bottom plate.

[0011] As a further improvement of the technical solution: the sample pad, the connection pad, the detection pad and the water absorption pad are arranged in a straight line.

[0012] As a further improvement of the technical solution: the bottom plate is made of PVC material.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The two bottom plates are spliced ​​together through the folding part, and the two bottom plates are provided with sample pads, connection pads, detection pads, quality inspection pads, detection lines and water absorption pads, and two tests are performed at the same time, which improves the accuracy of the test data and shortens the test time;

[0015] The two bottom plates can be folded and glued together by pressure-sensitive adhesive and isolation paper after the test is completed to prevent the toxic substances in the tested solution from diffusing outwards.

[0016] Once the operator does not wear gloves or performs other improper operations, the hand pad can prevent the fingers holding the absorbent pad from contacting the solution remaining on the absorbent pad and thus contacting some pathogenic factors.

[0028] Specifically, the upper side walls of the two base plates 1 are provided with pressure-sensitive adhesives 3, and isolation papers 5 are provided on the two pressure-sensitive adhesives 3. The cross-sections of the two pressure-sensitive adhesives 3 are relatively concave. The isolation papers 5 are torn off, and then the two base plates 1 are relatively attached together to seal the solution inside, thereby reducing the leakage of pathogenic factors in the solution and the risk of infection.

[0029] Specifically, a hand pad 4 is fixedly connected to the bottom side wall of one of the base plates 1. The solution contains infectious pathogenic viruses or bacteria, and these pathogenic factors (viruses or bacteria, etc.) will remain on the absorbent pad 11. Once the operator does not wear gloves or performs other improper operations, the fingers holding the absorbent pad will come into contact with these pathogenic factors, which poses a great risk of infection. The use of the hand pad 4 can avoid these problems.

[0030] Specifically, the sample pad 6 , the connection pad 7 , the detection pad 8 and the water absorption pad 11 are all bonded to the bottom plate 1 .

[0031] Specifically, the sample pad 6 , the connection pad 7 , the detection pad 8 and the absorbent pad 11 are arranged in a straight line to facilitate the penetration of the solution.

[0032] Specifically, the bottom plate 1 is made of PVC material.

[0033] The working principle of the utility model is: when in use, first drip the solution to be tested on the two sample pads 6 respectively, the sample pad 6 absorbs the solution and penetrates the solution into the connecting pad 7, the solution penetrates into the detection pad 8 through the connecting pad 7, and then the solution passes through the quality inspection line 9 and the detection line 10. If Zhijiang County 9 and the detection line 10 appear at the same time, it is positive. If the quality inspection line does not show and the detection line 10 shows, it is negative. If neither the quality inspection line 9 nor the detection line 10 shows, it means that the test strip is broken and needs to be tested again. At the same time, the two bottom plates 1 are operated for testing and the test results are compared, which has better accuracy and shortens the detection time. After the test is completed, the isolation paper 5 is torn off, and then the two bottom plates 1 are relatively fitted together to seal the solution inside, thereby reducing the leakage of pathogenic factors in the solution and the risk of infection.
