Abstract
Description
Technical Field
[0001] The utility model relates to the field of reagent cards, in particular to a high-sensitivity cardiac troponin I detection reagent card. Background Art
[0002] Troponin (Tn) is a group of contractile proteins present in skeletal muscle and myocardial cells. Cardiac troponin (cTn) is a group of proteins in the troponin complex that are related to myocardial contractile function. It consists of cardiac troponin T (cTnT, which is the part of the regulatory protein), troponin I (cTnI, which contains inhibitory factors) and troponin C (cTnI, which contains inhibitory factors). cTnI is a protein complex composed of three subunits: cTnC, cTnI subunit, and cTnI subunit. Under normal circumstances, the content of troponin TnI and TnT in the blood is very small. When myocardial cells are damaged, cardiac troponin I and T are released into the blood circulation. If a large area of damage occurs, high concentrations of cardiac troponin I and T will appear in the blood, which determines its specificity in indicating myocardial damage. cTnI is the only TnI isomer in human myocardial fibers. About 3% of cTnI is free in the cytoplasm, and the rest is bound to myocardial structural proteins. When myocardial damage occurs, early free The isolated cTnI is rapidly released into the blood, and the cTnI level increases 4-6 hours after myocardial injury. Subsequently, the myocardial structural protein is degraded, and cTnI is continuously released, reaching a peak after 12-18 hours and maintaining for 5-7 days. cTnI is not expressed in skeletal muscle. Its biochemical properties determine its high specificity and sensitivity as an indicator of myocardial injury. Therefore, cTnI has been used as a standard diagnostic method for acute myocardial infarction, especially when there is no abnormality in the electrocardiogram test, the cTnI indicator can be used as a diagnostic method. Therefore, a highly sensitive cTnI kit is needed clinically.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0029] The following describes an embodiment of the utility model based on its overall structure.
[0030] Embodiment 1:
[0031] A high-sensitivity cardiac troponin I detection reagent card, such as Figure 1-Figure 5 As shown, it includes a shell 1, a rotating groove 2 is opened on one side of the top of the shell 1, a convex groove 3 is rotatably connected to the inside of the rotating groove 2 through a rotating shaft, a sliding groove 4 is opened at the bottom of the convex groove 3, and a sample pad 5 is slidably engaged inside the sliding groove 4. By opening the rotating groove 2 on one side of the top of the shell 1 and connecting the convex groove 3 to the rotating groove 2 through a rotating shaft, the user can easily flip the convex groove 3 to collect and test blood samples, making the operation easier and improving the user experience. At the same time, the sliding groove 4 opened at the bottom of the convex groove 3 and the sample pad 5 slidably engaged inside reduce the difficulty of production, and the sample pad 5 can be easily slid and engaged in the sliding groove 4, which is convenient for installation during production.
[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A limiting plate 6 is fixedly connected to one side of the top of the convex groove 3, and the limiting plate 6 is a key-shaped structure. By setting the limiting plate 6, the lifting operation of the convex groove 3 can be facilitated, and then the subsequent blood dripping operation can be facilitated, which reduces the complexity of lifting the convex groove 3 and improves the convenience of use. At the same time, the key-shaped structure design of the limiting plate 6 increases the structural strength, so that the convex groove 3 will not be pressed into the accommodating groove 10 during transportation.
[0033] See also Figure 3A top block 7 is fixedly connected to the inner bottom of the shell 1, and a test strip 8 is arranged on the top of the top block 7. The design of the top block 7 enables the test strip 8 to reliably contact the sample pad 5, ensuring that the blood can be reliably transferred to the test strip 8 to achieve subsequent detection operations. At the same time, by fixing the top block 7 on the inner bottom of the shell 1, it can be ensured that the test strip 8 is stably supported and positioned, so that the test strip 8 can remain flat and stable during the detection process, thereby improving the accuracy and reliability of the detection.
[0034] See also Figure 3 A support block 9 is arranged on one side of the top block 7, and a plurality of support blocks 9 are arranged, and the plurality of support blocks 9 are arranged linearly and evenly. By arranging a plurality of support blocks 9 on one side of the top block 7, the support blocks are arranged linearly and evenly, which can more stably support the test paper 8 and prevent it from bending or deformation during transportation and detection, thereby helping to improve the accuracy and reliability of detection. At the same time, the arrangement of the plurality of support blocks 9 also increases the contact area between the test paper 8 and the housing 1, so that the test paper 8 can more reliably absorb and transfer the detection liquid, thereby further improving the accuracy and efficiency of the detection.
[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A receiving groove 10 is provided on one side of the rotating groove 2, and the receiving groove 10 is matched with the convex groove 3. By providing the receiving groove 10 on one side of the rotating groove 2 and matching it with the convex groove 3, a stable return space is provided for the convex groove 3, so that the convex groove 3 can be accurately embedded in the receiving groove 10 after flipping, ensuring the stability and reliability of the structure. At the same time, the design of the receiving groove 10 also helps to protect the convex groove 3 and the sample pad 5 inside it from external contamination or damage. When the convex groove 3 is embedded in the receiving groove 10, it is within the protection of the shell 1, reducing contact with the outside world, thereby reducing the risk of contamination.
[0036] The implementation principle of the utility model is as follows: first, before the test is needed, the convex groove 3 is turned over so that the bottom of the convex groove 3 can be on the surface, and then the blood drop directly touches the sample pad 5 so that the sample pad 5 can absorb the blood, and then the convex groove 3 is turned over so that the convex groove 3 is buckled back into the inside of the receiving groove 10. At this time, the test paper 8 lifted by the support block 9 is in contact with each other, and the blood flows to the test paper 8. Then a diluent is added, and the diluent dilutes the blood and moves along the test paper 8 to complete the test. The support block 9 can ensure that the test paper 8 remains stable and is placed inside the housing 1.
[0037] Embodiment 2:
[0038] See also Figure 4A mounting groove 11 is provided at the bottom of the convex groove 3, and the mounting groove 11 is fixedly connected to the sample pad 5. By providing the mounting groove 11 at the bottom of the convex groove 3 and fixing it with the sample pad 5, the stability and reliability of the sample pad 5 are ensured, so that the sample pad 5 can be firmly fixed on the convex groove 3 and will not move or fall off during operation, thereby ensuring the accuracy and repeatability of the detection. At the same time, the fixed connection between the mounting groove 11 and the sample pad 5 improves the structural strength of the reagent card, and the manufacturer can glue the sample pad 5 in the mounting groove 11, thereby improving the production efficiency.
[0039] See also Figure 4 A support block 12 is provided below the receiving groove 10, and the top of the support block 12 abuts against the test paper 8. By providing the support block 12 below the receiving groove 10, it can be ensured that when the convex groove 3 is buckled in the receiving groove 10, the test paper 8 can be stably supported. The top of the support block 12 abuts against the test paper 8, providing a flat and solid supporting surface for the test paper 8, which helps to maintain the flatness and stability of the test paper 8. At the same time, the support block 12 helps to facilitate the transfer of blood in the test paper 8. When the convex groove 3 is buckled, the sample pad 5 and the test paper 8 are tightly fitted, and the sample on the sample pad 5 is transferred to the test paper 8, thereby improving the accuracy and efficiency of the detection.
[0040] The implementation principle of the utility model is as follows: firstly, as a replacement for the method of installing the sample pad 5 by sliding engagement in the first embodiment, a directly protruding fixed sample pad 5 is adopted to avoid using a protruding top block 7 to ensure contact, thereby improving the reliability of contact.
