Description

Technical Field

[0001] This invention specifically relates to the field of detection card technology, and more specifically to a canine distemper detection card with a safety protection structure. Background Technology

[0002] Canine distemper, also known as canine distemper virus, is a highly contagious and deadly disease in dogs. It is primarily transmitted through direct contact and is not a zoonotic disease. Symptoms in dogs infected with canine distemper include high fever, extreme lethargy, copious nasal and ocular discharge, and possibly diarrhea. Canine distemper test strips utilize rapid immunochromatographic assays to detect canine distemper antigens. After the sample is added to the well, it moves along the chromatographic membrane with a colloidal gold-labeled CDV monoclonal antibody. If the CDV antigen is present in the sample, it binds to the antibody on the test line, resulting in a wine-red color. If the CDV antigen is absent, no color reaction occurs. A search revealed a canine distemper virus test strip, a typical example being publication number CN206832819U. This device has an opening on the sidewall of the cavity corresponding to the sample pad. Two notches are provided, allowing excess sample liquid to flow out and reducing the false negative rate. The cover can be slid out of the groove in the shell to pour excess sample liquid into the waste liquid pool, which is safe and environmentally friendly. The baffle divides the area other than the cavity into two parts: one part can be used to store waste liquid, and the other part can be used to put the label paper. The limiting block on the cavity can effectively prevent the test paper from moving in the vertical direction. However, the safety protection effect of this test card is poor. The detection part is exposed to contact with the external environment, and the detection effect is greatly affected by the external environment. At the same time, whether the sample is being tested or the sample is being added to the sampling hole, if the plane on which the test card is placed is tilted, it will affect the detection effect. Summary of the Invention

[0003] The purpose of this invention is to provide a canine distemper test card with a safety protection structure, in order to solve the problem that the test card device and the external environment are in contact, which will affect the test results, and to prevent the test card from tilting, which will affect the test results.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a canine distemper test card with a safety protection structure, comprising a shell, a sample application hole at the top of the shell, an observation groove at the top of the shell on one side of the sample application hole, a cavity inside the shell, a test strip inside the cavity, a test line and a quality inspection line respectively provided on the test strip, a mark in English on the top of the shell on one side of the observation groove, and a safety protection component at the top of the shell;

[0005] The safety protection component includes a first groove on the top of the housing, a rotating column rotatably connected inside the first groove, a fixed sleeve fixedly connected to the outside of the rotating column, and a cover plate fixedly connected to the outer surface of the fixed sleeve.

[0006] Preferably, a fixing seat is threadedly fixed to the outer side of the cover plate, a first spring is welded to the other side of the fixing seat, a pull rope is fixedly connected to the other end of the first spring, and an inner groove is opened on one side of the inner wall of the groove. A first telescopic rod is fixedly connected to the end of the inner groove, and the other end of the first telescopic rod is fixedly connected to the pull rope.

[0007] With the above technical solution, when the cover is opened, the cover is opened and returned to its original position by the first spring.

[0008] Preferably, a protective plate is fixedly connected to the bottom of the cover plate. Two sets of protective plates are provided. The two sets of protective plates are cylindrical and rectangular in appearance, respectively, and the dimensions of the protective plates on both sides are respectively matched with the observation groove and the sample feeding hole.

[0009] The above technical solution prevents the detection area from being affected by moisture.

[0010] Preferably, the other end of the cover plate is fixedly connected to an insert plate, and a second groove is provided on the top of the housing near the sample filling hole.

[0011] Using the above technical solution, the insert plate is inserted into the second groove to close the detection area.

[0012] Preferably, a second telescopic rod is fixedly connected to both sides of the outer surface of the insert plate, a second spring is fixedly connected inside the second telescopic rod, and a limit block is fixedly connected to the other end of the telescopic rod. The limit block is cylindrical in shape, and limit holes are opened on both sides of the inner wall of the second groove.

[0013] The above technical solution secures the sealed cover plate.

[0014] Preferably, a first cylindrical groove is provided on both sides of the top of the housing close to the second groove. The position of the first cylindrical groove corresponds to the limiting hole, and the limiting hole penetrates the inner wall of the first cylindrical groove. A telescopic column is fixedly connected inside the first cylindrical groove. A pressure block is fixedly connected to the top of the telescopic column, and a fixing ring is welded to the outer surface of the telescopic column.

[0015] Through the above technical solution, the telescopic column drives the fixed ring to move up and down.

[0016] Preferably, a third telescopic rod is fixedly connected inside the fixed ring, a third spring is fixedly connected inside the third telescopic rod, and a pressure plate is fixedly connected to the other end of the telescopic rod.

[0017] The above technical solution allows the limiting block to be squeezed out of the limiting hole.

[0018] Preferably, the housing has a second cylindrical groove inside, a rotating block is provided at the top of the second cylindrical groove, and a threaded rod fixedly connected to the other end of the rotating block rotates through the top of the second cylindrical groove. A threaded sleeve is engaged with the outside of the threaded rod.

[0019] The above technical solution adjusts the tilt angle of the detection card.

[0020] Preferably, the bottom of the threaded sleeve is rotatably connected to a bearing, the other end of the bearing is fixedly connected to a support column, and the other end of the support column is fixedly connected to an anti-slip pad.

[0021] The above technical solutions increase the friction of the support column and improve the stability of the support.

[0022] Compared with the prior art, the beneficial effects of the present invention are: a canine distemper detection card with a safety protection structure.

[0023] The safety protection component addresses the issue that the detection area of ​​the test card is largely exposed to the external environment, making its effectiveness highly susceptible to environmental influences. Furthermore, tilting the plane on which the test card is placed, whether during sample testing or sample addition, will affect the detection results. The safety protection component incorporates a rotating column, cover plate, and telescopic column. Rotating the cover plate opens and closes the detection area via the rotating column. Pressing down on the telescopic column causes it to extend and retract, moving the fixing ring and the third telescopic rod within the first cylindrical groove. The extension and retraction of the third telescopic rod forces the limiting block, which is engaged in the limiting hole, out of the limiting hole. Simultaneously, the insert plate and cover plate on one side of the limiting block rotate to the other side under the elasticity of the first spring, thus opening the sample addition hole for sample addition and testing. Conversely, rotating the cover plate inserts the insert plate on one side into the second groove, and the limiting block on the other side is engaged by the elastic extension and retraction of the second spring. In the sampling hole, since the limiting hole is connected to the first cylindrical groove, the limiting block is inserted into the first cylindrical groove through the limiting hole to seal the sampling hole, preventing the detection part from contacting the external environment during testing and improving the accuracy of the test results. In actual operation, pressing the pressure block can open the cover plate to add the sample for testing, and pushing the cover plate can seal the detection part. It is simple and convenient. The protective plate is equipped with a drying layer to prevent moisture from entering the test card when it is not in use, which would cause the test card to fail. Through the threaded rod, threaded sleeve and support column, the rotating block is rotated, and the rotating block drives the threaded rod to rotate. The threaded sleeve engaged on the outside of the threaded rod moves up and down on the outside of the threaded rod and drives the support column to move and contact the plane, adjusting the inclination of the shell to prevent the plane of the test card from tilting, which would make it difficult for the sample to penetrate along the test paper when adding the sample to the sampling hole or testing the sample, thus affecting the test effect.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-10 The present invention provides a technical solution: a canine distemper detection card with a safety protection structure;

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 10 As shown, the device includes a housing 1, with a sample application port 2 on the top. An observation groove 3 is located on the top of the housing on one side of the sample application port 2. A cavity 4 is located inside the housing 1, and a test strip 5 is placed inside the cavity 4. The test strip 5 has a detection line 6 and a quality control line 7. A label 8 is marked on the top of the housing 1 on one side of the observation groove 3. A safety protection component 9 is located on the top of the housing 1. After the sample is added to the sample application port 2, if the CDV antigen is present in the sample, it will interact with the detection line 6. The antibody binds to the sample and appears wine red. If the sample does not contain CDV antigen, no color reaction will occur. The safety protection component 9 is used to seal and protect the detection area of ​​the test card from moisture to prevent the detection area from being affected by the external environment. The tilt of the test card is adjusted to make the tilt of the test card adapt to the plane. The safety protection component 9 includes a first groove 901 opened on the top of the housing 1. A rotating column 902 is rotatably connected inside the first groove 901. A fixing sleeve 903 is fixedly connected to the outside of the rotating column 902. A cover plate 904 is fixedly connected to the outer surface of the fixing sleeve 903.

[0038] In the above scheme, the cover plate 904 is rotated, and the cover plate 904 rotates in the first groove 901 through the rotating column 902 on one side, thereby opening or closing the opening end of the detection part to detect or seal the sample, so as to prevent the exposed detection part from contacting the external environment during sample detection and affecting the accuracy of the detection results.

[0039] like Figure 2 and Figure 10 As shown, further, a fixing seat 905 is threadedly fixed to the outer side of the cover plate 904, a first spring 906 is welded to the other side of the fixing seat 905, a pull rope 908 is fixedly connected to the other end of the first spring 906, and an inner groove 907 is opened on one side of the inner wall of the first groove 901. A first telescopic rod 909 is fixedly connected to the end of the inner groove 907, and the other end of the first telescopic rod 909 is fixedly connected to the pull rope 908.

[0040] In the further embodiment described above, when the cover plate 904 is opened, the first spring 906 on one side of the cover plate 904 elastically extends and retracts to pull the cover plate 904. At the same time, the other end of the first spring 906 moves within the inner groove 907 via the pull rope 908. The first telescopic rod 909 at one end of the pull rope 908 elastically extends and retracts. The cover plate 904 rotates and opens the detection area via the rotating column 902 on one side, making it more convenient to add the sample to the sample feeding hole 2 for detection when the cover plate 904 is opened.

[0041] like Figure 4 As shown, further, a protective plate 910 is fixedly connected to the bottom of the cover plate 904. There are two sets of protective plates 910. The appearance of the two sets of protective plates 910 is cylindrical and rectangular, respectively, and the dimensions of the two protective plates 910 on both sides are respectively matched with the observation groove 3 and the sample feeding hole 2.

[0042] In the above-mentioned further solution, when the cover plate 904 seals and closes the detection area, the protective plate 910 moves with the cover plate 904 into the interior of the detection area, and a drying layer is provided inside the protective plate 910 to prevent moisture from entering the detection card when it is not in use, which would cause the detection card to fail.

[0043] like Figure 4 and Figure 6 As shown, the other end of the cover plate 904 is fixedly connected to the insert plate 912. The top of the housing 1 near the sample hole 2 is provided with a second groove 911. When the detection part is closed, the insert plate 912 moves with the cover plate 904 and enters the interior of the second groove 911 to close and seal the detection part.

[0044] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, further, a second telescopic rod 913 is fixedly connected to both sides of the outer surface of the insert plate 912, a second spring 914 is fixedly connected inside the second telescopic rod 913, and a limit block 915 is fixedly connected to the other end of the telescopic rod 913. The limit block 915 is cylindrical in appearance, and limit holes 916 are opened on both sides of the inner wall of the second groove 911.

[0045] In the further embodiment described above, the second telescopic rod 913 on one side of the insert plate 912 moves with the insert plate 912. When the second telescopic rod 913 moves to the position of the limiting hole 916 while conforming to the second groove 911, the second telescopic rod 913 elastically extends and retracts through the internal second spring 914. At the same time, the limiting block 915 elastically extends and retracts with the second telescopic rod 913 and is inserted into the limiting hole 916 to fix the closed cover plate 904 and prevent the cover plate 904 from being opened. The limiting block 915 directly enters the interior of the first cylindrical groove 917 through the through limiting hole 916 and the first cylindrical groove 917.

[0046] like Figure 6 and Figure 9 As shown, the top of the housing 1, which is close to the second groove 911, has a first cylindrical groove 917 on both sides. The position of the first cylindrical groove 917 corresponds to the limiting hole 916, and the limiting hole 916 passes through the inner wall of the first cylindrical groove 917. A telescopic column 919 is fixedly connected inside the first cylindrical groove 917. A pressure block 918 is fixedly connected to the top of the telescopic column 919, and a fixing ring 920 is welded to the outer surface of the telescopic column 919. When the pressure block 918 is pressed, the pressure block 918 drives the telescopic column 919 to move telescopically. At the same time, the fixing ring 920 on the outer side of the telescopic column 919 moves with the telescopic column 919.

[0047] like Figure 5 and Figure 8 As shown, further, a third telescopic rod 921 is fixedly connected inside the fixed ring 920, a third spring 922 is fixedly connected inside the third telescopic rod 921, and the other end of the telescopic rod 921 is fixedly connected to a pressure plate 923.

[0048] In the further embodiment described above, pressing down on the pressure block 918 causes the telescopic column 919 to extend and retract, which in turn moves the fixing ring 920 and the third telescopic rod 921 within the first cylindrical groove 917. When the third telescopic rod 921 moves, the pressure plate 923 at one end of the third telescopic rod 921 contacts the limiting block 915 inserted into the first cylindrical groove 917. The third telescopic rod 921 then extends and retracts elastically through the internal third spring 922. This elastic extension and retraction of the third telescopic rod 921 causes the pressure plate 923 to extend and retract. The elastic extension and retraction of the pressure plate 923 pushes the limiting block 915, which is inserted into the limiting hole 916, out of the limiting hole 916. Then, the limiting block 915 extends and retracts elastically through the second spring 914 within the second telescopic rod 913. The insert plate 912 and the cover plate 904 at one end of the second telescopic rod 913 open the closed cover plate 904 under the elasticity of the first spring 906. In actual operation, pressing the pressure block 918 is sufficient to open the cover plate 904, which is more convenient.

[0049] like Figure 3 As shown, a second cylindrical groove 924 is provided inside the housing 1. A rotating block 925 is provided at the top of the second cylindrical groove 924. A threaded rod 926 fixedly connected to the other end of the rotating block 925 rotates through the top of the second cylindrical groove 924. A threaded sleeve 927 is engaged with the outer side of the threaded rod 926.

[0050] In the above scheme, rotating block 925 drives threaded rod 926 to rotate. Threaded sleeve 927, which meshes with threaded rod 926 on the outside, moves up and down on the outside of threaded rod 926 and drives the bottom support column 929 to move and contact the plane, adjusting the inclination of housing 1 to prevent the plane of the test card from tilting, which would make it difficult for the sample to penetrate along the test paper when adding or testing the sample into sample hole 2, thus affecting the detection effect.

[0051] like Figure 3 As shown, the bottom of the threaded sleeve 927 is rotatably connected to a bearing 928, the other end of the bearing 928 is fixedly connected to a support column 929, and the other end of the support column 929 is fixedly connected to an anti-slip pad 930. The anti-slip pad 930 at the bottom of the support column 929 increases the support friction of the support column 929 and improves the support stability.

[0052] The terms “center,” “longitudinal,” “lateral,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of the present invention.
