Description

Technical Field

[0001] This utility model relates to the field of biomedical detection technology, and in particular to a rapid detection card for hepatitis virus antigens. Background Technology

[0002] Biomedical testing refers to the technology of using various biological and chemical methods to detect and analyze physiological, biochemical, genetic, and pathological indicators of organisms (including humans, animals, and plants).

[0003] Hepatitis viruses, especially hepatitis B virus (HBV) and hepatitis C virus (HCV), are a global public health problem. Traditional hepatitis virus antigen testing relies on laboratory equipment, which is complex, time-consuming, and requires highly skilled operators, hindering rapid screening and timely intervention. When testing samples using test strips, the exposed portion of the sampling area is small, resulting in a reduced sample volume. This reduced sample volume means that the target substances (such as antibodies and antigens) in the sample cannot fully react with the chemical reagents on the test strip, or the reaction speed is slowed down. This incomplete or slow reaction directly affects the accuracy and speed of the test results, thus reducing testing efficiency and practicality. Therefore, a new rapid hepatitis virus antigen test strip needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid hepatitis virus antigen detection card.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid hepatitis virus antigen test card includes a housing. Multiple movable plates are slidably mounted inside the housing via movable slots. A sliding rod is slidably mounted on the inner wall of each movable slot via a sliding groove. A sliding sleeve is slidably mounted on the outer wall of each sliding rod. A spring is mounted on the outer wall of each sliding rod. Each spring's two ends are elastically connected to the inner wall of the corresponding sliding groove and the outer wall of the sliding sleeve, respectively. The upper end face of each sliding sleeve is fixedly connected to the outer wall of the corresponding movable plate via a connecting mechanism. A connecting plate is fixedly mounted on the upper end face of each movable plate. A sampling plate and a display plate are fixedly mounted on the upper end face of each connecting plate. The sampling plate and the display plate are fixedly connected via a flow plate. A sampling frame that cooperates with the sampling plate is fixedly mounted on the upper end face of each movable plate via a support mechanism. A buckle is fixedly mounted at the end of each movable plate via a connecting mechanism. An installation slot is formed on the upper end face of the housing. A cover plate is fixedly connected inside the installation slot via an installation mechanism. The upper end face of the cover plate has a locking interface that cooperates with multiple buckles.

[0007] Preferably, the connecting mechanism includes a connecting plate fixedly installed on the upper end face of the sliding sleeve, and the end of the connecting plate is fixedly connected to the outer wall of the moving plate.

[0008] Preferably, the support mechanism includes two support rods fixedly installed on the upper surface of the movable plate, and the ends of the two support rods are fixedly connected to the bottom wall of the sampling frame.

[0009] Preferably, the connecting mechanism includes a connecting block fixedly installed at the end of the movable plate, and the buckle is fixedly installed on the inner wall of the connecting block.

[0010] Preferably, the installation mechanism includes a mounting frame that is sealed and slidably installed inside the mounting groove, and the end of the mounting frame is fixedly connected to the bottom wall of the cover plate.

[0011] Preferably, the upper surface of the cover plate has multiple observation ports, and a transparent observation plate is fixedly installed inside each observation port.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as springs, sliders, and connecting plates, when the fixing of the moving plate is released, the spring can release elastic potential energy to drive the sliding sleeve to slide on the outer wall of the sliding rod. The sliding sleeve then drives the moving plate to move outward inside the moving groove through the connecting plate. This increases the exposed area of ​​the sampling plate, allowing the sample to come into contact with the chemical reagents on the sampling plate more easily and fully, thereby improving the detection efficiency.

[0014] 2. By setting up components such as buckles, boxes, and covers, the movable plate can be fixed inside the movable slot when the outer wall of the buckle fits against the inner wall of the card interface. The protection of the box and cover can prevent debris and dust from contaminating the sample, thereby ensuring the accuracy of the test. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A rapid hepatitis virus antigen test card includes a box body 1. Multiple movable plates 2 are slidably installed inside the box body 1 via movable grooves. A sliding rod 3 is slidably installed on the inner wall of each movable groove via a sliding groove. A sliding sleeve 4 is slidably installed on the outer wall of each sliding rod 3. A spring 5 is installed on the outer wall of each sliding rod 3. The two ends of each spring 5 are elastically connected to the inner wall of the corresponding sliding groove and the outer wall of the sliding sleeve 4, respectively. The upper end face of each sliding sleeve 4 is fixedly connected to the outer wall of the corresponding movable plate 2 via a connecting mechanism. The connecting mechanism includes a connecting plate 6 fixedly installed on the upper end face of the sliding sleeve 4. The end of the connecting plate 6 is fixedly connected to the outer wall of the movable plate 2.

[0024] Each movable plate 2 has a connecting plate 7 fixedly installed on its upper surface. Each connecting plate 7 has a sampling plate 8 and a display plate 9 fixedly installed on its upper surface. The corresponding sampling plate 8 and display plate 9 are fixedly connected by a flow plate 10. Each movable plate 2 has a sampling frame 12 that cooperates with the sampling plate 8 fixedly installed on its upper surface by a support mechanism. The support mechanism includes two support rods 11 fixedly installed on the upper surface of the movable plate 2. The ends of the two support rods 11 are fixedly connected to the bottom wall of the sampling frame 12.

[0025] Each movable plate 2 has a buckle 14 fixedly installed at its end via a connecting mechanism. The connecting mechanism includes a connecting block 13 fixedly installed at the end of the movable plate 2. The buckle 14 is fixedly installed on the inner wall of the connecting block 13. The upper surface of the box body 1 has an installation groove. A cover plate 16 is fixedly connected inside the installation groove via an installation mechanism. The installation mechanism includes an installation frame 15 that is sealed and slidably installed inside the installation groove. The end of the installation frame 15 is fixedly connected to the bottom wall of the cover plate 16. The upper surface of the cover plate 16 has a card interface that mates with multiple buckles 14. The upper surface of the cover plate 16 has multiple observation ports. A transparent observation plate 17 is fixedly installed inside each observation port.

[0026] When using this utility model, the buckle 14 can be pressed down through the card interface, thereby disengaging the buckle 14 from the inside of the card interface. At this time, the spring 5 can release elastic potential energy to drive the sliding sleeve 4 to slide on the outer wall of the sliding rod 3. During the movement, the sliding sleeve 4 can drive the moving plate 2 to move outward inside the moving groove through the connecting plate 6, thereby allowing the moving plate 2 to move the sampling plate 8 and the sampling frame 12 to the outside of the box body 1. This increases the exposed area of ​​the sampling plate 8. The user can drip the collected sample into the sampling plate 8 through the sampling frame 12, thereby making it easier and more sufficient for the sample to come into contact with the chemical reagents on the sampling plate 8, thus improving the detection efficiency. After the sample and reagent are mixed, the display plate 9 can be wetted in the sampling plate 8 through the cooperation of the flow plate 10.

[0027] While waiting for the display panel 9 to display the results, the moving plate 2 can be pushed by the connecting block 13. During the movement of the moving plate 2, the spring 5 can be squeezed by the connecting plate 6 and the sliding sleeve 4. At the same time, the cover plate 16 can squeeze the buckle 14. When the moving plate 2 is completely moved into the moving groove, the outer wall of the buckle 14 can fit with the inner wall of the card interface, thereby fixing the moving plate 2 inside the moving groove. With the protection of the box body 1 and the cover plate 16, the sample can be prevented from being contaminated by debris and dust, thus ensuring the accuracy of the test. At this time, the display panel 9 can be observed through the transparent observation plate 17.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
