Description

Technical Field

[0001] The utility model relates to the technical field of animal detection cards, and more specifically to a colloidal gold detection card for canine parvovirus antigen. Background Technique

[0002] In order to quickly detect and diagnose canine parvovirus and the infectious diseases caused by it, the colloidal gold immunochromatography technique is applied. As a new diagnostic technique, the basic principle is as follows: A colloidal gold is used to label an antigen or an antibody, and the corresponding paired antigen or antibody is coated on the nitrocellulose membrane of the reagent. When the sample contains the corresponding specific antibody or antigen during detection, the colloidal gold-labeled particles combine with the ligand in the sample to form an antigen-antibody complex, and then chromatograph on the nitrocellulose membrane and are captured by the coated antigen or antibody, forming a visible detection T line. Under certain conditions, the strength of the T line is positively or negatively correlated with the concentration in the sample, thus realizing the detection; it has the advantages of simple operation, rapid reaction, high sensitivity, strong specificity, suitability for on-site detection, economy and practicality, etc.

[0003] Deficiencies of the prior art: During on-site detection, due to the unstable environment, the instrument is likely to be knocked over or dropped, which will affect the accuracy of the test and also the utilization rate of the instrument; when diluting the sample with a diluent, it needs to be shaken well and then left to stand to take the supernatant. If the container for the diluent is too large, it will be a waste of the diluent. Using a test tube for dilution is a more reasonable reaction, but the waiting time for standing is very long, and there is a risk of being knocked over when placed aside. Content of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a colloidal gold detection card for canine parvovirus antigen to solve the problems existing in the above-mentioned background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A colloidal gold detection card for canine parvovirus antigen includes an anti-slip mechanism, and also includes: a protection mechanism, a dissolution mechanism and a detection mechanism. The side of the anti-slip mechanism is fixedly connected to the side of the protection mechanism. The anti-slip mechanism includes an anti-slip pad and anti-slip lines. The protection mechanism includes an upper case and a lower case. The top of the anti-slip pad is fixedly connected to the bottom of the lower case. The side of the anti-slip lines is fixedly connected to the side of the upper case, and the side of the anti-slip lines is fixedly connected to the side of the lower case. A sample inlet is opened at the top end of the upper case, and an observation port is opened at the top end of the upper case.

[0006] Furthermore, the dissolution mechanism includes a test tube and a stable table. A fixing band is fixedly connected to the top end of the test tube, and a lid is fixedly connected to the top end of the fixing band. A card slot is opened at the top end of the stable table, and the bottom end of the test tube is connected to the inside of the card slot. The inside of the test tube is connected to the outside of the lid.

[0007] Further, the protection mechanism includes a splash-proof shell and a card hole. The inner side of the upper housing is fixedly connected to the top end of the splash-proof shell, and the inner side of the upper housing is fixedly connected to the bottom end of the card hole.

[0008] Further, the protection mechanism includes a buckle and a fixing buckle. The inner side of the lower housing is fixedly connected to the bottom of the buckle, and the inner side of the lower housing is fixedly connected to the bottom of the fixing buckle. A detection mechanism is fixedly connected to the side of the fixing buckle.

[0009] Further, the detection mechanism includes a sample pad, a conjugate pad, a nitrocellulose membrane, and a blotting paper. The top end of the sample pad is fixedly connected to the bottom end of the conjugate pad, the top end of the conjugate pad is fixedly connected to the bottom end of the nitrocellulose membrane, and the top end of the nitrocellulose membrane is fixedly connected to the bottom end of the blotting paper.

[0010] Further, a conjugate pad is fixedly connected to the inner side of the fixing buckle, a nitrocellulose membrane is fixedly connected to the inner side of the fixing buckle, and a card hole is fixedly connected to the outer side of the buckle.

[0011] Technical effects and advantages of the present utility model:

[0012] 1. By providing an anti-slip pad and anti-slip lines, the design of the anti-slip pad and anti-slip lines can significantly increase the friction between the test card and the operation tabletop, preventing accidental accidents caused by sliding during the operation, thereby ensuring the safety of the operator and the test card itself; by adding an anti-slip pad and anti-slip lines, the gold colloid test card can be placed more stably, and is not easily displaced due to slight touch or vibration, which is crucial for maintaining the stability and accuracy of the detection process; enabling the test card to be placed on the operation tabletop more quickly and fixed in position, reducing the time for adjusting the position, thereby improving the efficiency of the entire detection process; the anti-slip pad can provide a certain buffering effect, reducing damage to the test card caused by improper operation or external collision, protecting the service life and performance of the test card.

[0013] 2. By providing a stable test tube platform, it is beneficial for support and stability. The test tube stable platform can stably support the test tube, ensuring the verticality and stability of the test tube during the experiment, effectively preventing the test tube from tipping or slipping due to external factors, thereby protecting the samples or reagents in the test tube from loss. Samples or diluents taken out of the test tube need to react, be observed, or analyzed in different steps. Without a fixed rack to support, it will lead to situations such as the test tube tipping over or slipping, threatening the accuracy and safety of the experimental results.

A sample inlet 203 is opened at the top of the upper housing 201, and an observation port 205 is opened at the top of the upper housing 201.

[0023] Among them, the dissolving mechanism 3 includes a test tube 301 and a stabilizing table 302. A fixing strap 304 is fixedly connected to the top end of the test tube 301. A lid 305 is fixedly connected to the top end of the fixing strap 304. A card slot 303 is formed in the top end of the stabilizing table 302. The bottom end of the test tube 301 is connected to the inner side of the card slot 303. The inner side of the test tube 301 is connected to the outer side of the lid 305.

[0024] Among them, the protection mechanism 2 includes a splash-proof shell 204 and a card hole 206. The inner side of the upper housing 201 is fixedly connected to the top end of the splash-proof shell 204. The inner side of the upper housing 201 is fixedly connected to the bottom end of the card hole 206.

[0025] Among them, the protection mechanism 2 includes a buckle 207 and a fixing buckle 208. The inner side of the lower housing 202 is fixedly connected to the bottom of the buckle 207. The inner side of the lower housing 202 is fixedly connected to the bottom of the fixing buckle 208. A detection mechanism 4 is fixedly connected to the side of the fixing buckle 208.

[0026] Among them, the detection mechanism 4 includes a sample pad 401, a conjugate pad 402, a nitrocellulose membrane 403, and a blotting paper 404. The top end of the sample pad 401 is fixedly connected to the bottom end of the conjugate pad 402. The top end of the conjugate pad 402 is fixedly connected to the bottom end of the nitrocellulose membrane 403.

[0028] The working principle of the present utility model: The test tube 301 contains a diluent buffer solution. Since the outer side of the lid 305 is connected to the inner side of the test tube 301, the diluent buffer solution will not flow out. When in use, a swab is used to dip an appropriate amount of sample and put it into the diluent buffer solution in the test tube 301 for dilution. After dilution, it needs to stand still for about 10 minutes. To avoid spilling of the sample diluent, it can be placed on the stabilizing table 302 and wait for it to stand still. Then, a dropper is used to take the upper clear liquid and drop the upper clear liquid into the sample inlet 203 opened at the top of the upper housing 201. The sample clear liquid drops onto the sample pad 401 through the splash-proof shell 204. Due to the diffusion of the liquid, after the solution passes through the conjugate pad 402, the antibody on the conjugate pad 402 is brought to the nitrocellulose membrane 403 together. Due to the combination of antigen and antibody, certain color development will occur on the nitrocellulose membrane 403. Due to the water absorption of the blotting paper 404, the sample clear liquid is carried along to flow. During the process of waiting for color development, it can be placed on the tabletop, and the anti-slip pad 101 will play an anti-slip role when contacting the tabletop. The anti-slip pattern 102 also plays an anti-slip role when holding the instrument.
