Description

Technical Field

[0001] The present invention relates to the technical field of blood testing, and more particularly to a device capable of detecting multiple proteins in plasma. Background Art

[0002] Blood testing is a medical procedure that analyzes various components of a blood sample to diagnose disease, assess health status, and monitor the effectiveness of treatment.

[0003] There are many ways to detect various proteins in plasma. Here are some common methods:

[0004] 1. Protein electrophoresis: This is a commonly used method for protein separation and analysis. Proteins are separated in gel according to their size, charge and other characteristics through electrophoresis, and then the proteins are quantitatively or qualitatively analyzed by staining or other detection methods.

[0005] 2. Immunoassay: Immunoassay uses the specific binding of antibodies to target proteins to detect the presence and concentration of proteins. Common immunoassay methods include ELISA (enzyme-linked immunosorbent assay), Western blotting, and immunofluorescence.

[0006] 3. Mass spectrometry: Mass spectrometry is a high-precision protein analysis method that can detect and quantify a variety of proteins in plasma. It ionizes protein molecules and performs mass analysis to determine the molecular weight and composition of proteins.

[0007] 4. Protein chip: Protein chip is a high-throughput protein detection technology that fixes a large number of proteins on the chip surface and then reacts with plasma samples to determine the presence and concentration of proteins in plasma by detecting signals on the chip.

[0008] These methods have their own advantages and disadvantages, and the appropriate method can be selected according to specific needs and research purposes. When conducting protein testing, attention should be paid to sample collection, processing and preservation to ensure the accuracy and reliability of the test results. In addition, the detection of proteins in plasma has important application value in medical diagnosis, disease monitoring, drug development and other fields. By detecting changes in specific proteins in plasma, it can help doctors diagnose diseases, evaluate treatment effects, monitor disease progression, etc.

[0009] However, most of these detection methods require the use of large equipment or can only be completed in specific places (hospitals, physical examination centers, etc.), and cannot be completed at home. Based on the above problems, we provide a device that can detect multiple proteins in plasma.

[0010] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to a person of ordinary skill in the art. Summary of the invention

[0011] In order to solve the problems raised in the above background technology, the present invention provides a device capable of detecting multiple proteins in plasma.

[0012] The present invention provides a device capable of detecting multiple proteins in plasma using the following technical solution:

[0013] A device capable of detecting multiple proteins in plasma comprises a detection rod, the top of which is provided with a groove; the groove comprises a sample addition area and a neodymium magnet area; a discharge port is provided at the side end of the groove for discharging liquid; a detection box, the side of which is provided with an insertion port for inserting the detection rod; a liquid crystal screen is mounted on the top of the detection box, a detection switch is also mounted on the top of the detection box, and a photomultiplier tube is arranged above the insertion port; a main control circuit board is also arranged inside the detection box for controlling various electrical components in the detection box.

[0014] Preferably, the interior of the detection box is also equipped with a battery box for supplying power to various electrical components in the detection box, and the side of the detection box is equipped with a switch.

[0015] Preferably, the trough body is an inclined structure for the flow of fluid.

[0016] Preferably, the photomultiplier tube is electrically connected to the battery box, the switch and the liquid crystal screen through a main control circuit board by wires.

[0017] Preferably, two track grooves are provided inside the groove body, and a push plate is slidably assembled between the two track grooves.

[0018] Preferably, a recess is provided at the bottom of the push plate, and the inner wall of the recess is rotatably connected to two rollers, a polygonal strip is inserted and assembled between the two rollers, a hair roller is passed through the middle of the polygonal strip, and the hair roller is eccentrically arranged on the polygonal strip.

[0019] Preferably, a placement groove is provided on the side of the push plate, and a pull ring is slidably connected inside the placement groove.

[0020] A method for using a device capable of detecting multiple proteins in plasma comprises the following steps:

[0021] S1. Drop the blood collected from the fingertips into the first EP tube. After natural sedimentation, use a dropper to absorb the supernatant and add it to the EP tube for antibody incubation. Mix well and oscillate for one minute. The tube has pre-stored enzyme-linked antigens of various antibodies to be detected. The enzyme-linked antigen is a fluorescent protein antibody. Use a dropper to transfer the liquid in the EP tube for antibody incubation to the EP tube for forming an antigen-antibody-magnetic bead complex. Mix well and oscillate for one minute. The tube has pre-stored magnetic bead-adsorbed antibodies of various antigens to be detected.

[0022] S2, then add the mixed reagents to the sample adding area in the tank body. When the reagents slowly flow through, the target protein will be adsorbed by the neodymium magnet in the neodymium magnet area. Then add distilled water to the sample adding area to wash away the remaining protein impurities. The excess liquid will flow out through the discharge port.

[0023] S3. Turn on the switch of the test box, mix the luminol reagent with the protein-fixed slot, then insert the test stick into the insertion port of the test box and press the test switch. The luminescence intensity of the sample can be detected by the photomultiplier tube, and converted into an electrical signal by the main control circuit board, and finally displayed on the LCD screen. The data and related scales can be used to characterize the overall protein level to determine the level of certain diseases.

[0024] In summary, the present invention includes the following beneficial technical effects:

[0025] 1. By turning on the switch of the test box, mixing the luminol reagent in the groove where the protein has been fixed, then inserting the test stick into the insertion port of the test box and pressing the test switch, the luminescence intensity of the sample can be detected by the photomultiplier tube, and converted into an electrical signal by the main control circuit board, and finally displayed on the LCD screen. The entire detection process only needs to be carried out in a small test box and several additional EP tubes, without the need for large precision instruments, with low cost and high promotion; at the same time, the blood concentration levels of multiple protein markers can be roughly measured, and the severity of the corresponding disease can be characterized by the total luminescence intensity, so as to establish disease classification.

[0026] 2. Pull the pull ring so that the pull ring is arranged on the top of the push plate, and then push the pull ring to move the push plate in the slot body. When the push plate moves, the two rollers will move in the slot body, thereby driving the polygonal strips to rotate, and then the wool roller can rotate in the slot body and clean the impurities and residues in the slot body. The wool roller is eccentrically arranged, and when facing the concave and convex surfaces in the slot body, it can also clean them. At the same time, when the two rollers move to the end section of the slot body, the wool roller can be eccentrically swung, so that the impurities on the wool roller can fall off through centrifugal force.

[0027] 3. When the two rollers rotate, the corresponding polygonal strips will be driven to rotate, so that the push plate rotates in the push plate, thereby cooperating with the spring telescopic rod to make the movable panel move up and down in the push plate, and squeeze the airbag, so that the jet pipe blows air into the tank body. Through this structural design, when the wool roller cleans the tank body, the tank body can also be sprayed with air, so that the impurities in the tank body and the inner wall of the tank body fall off, which is more conducive to the wool roller cleaning and impurities adhering to the tank body.

[0044] Specifically, two track grooves 104 are provided inside the groove body 100 , and a push plate 105 is slidably assembled between the two track grooves 104 .

[0045] Specifically, a recess 106 is provided at the bottom of the push plate 105, and two rollers 107 are rotatably connected to the inner wall of the recess 106.

[0046] Specifically, a placement groove 110 is formed on the side of the push plate 105 , and a pull ring 111 is slidably connected inside the placement groove 110 .

[0047] When cleaning the trough body 100, the pull ring 111 is pulled so that the pull ring 111 is arranged on the top of the push plate 105, and then the pull ring 111 is pushed to move the push plate 105 in the trough body 100. When the push plate 105 moves, the two rollers 105 will move in the trough body 100, thereby driving the polygonal strip 108 to rotate, and then the hair roller 109 can rotate in the trough body 100 and clean the impurities and residues in the trough body 100. Moreover, the hair roller 109 is eccentrically arranged, and when facing the concave and convex surfaces in the trough body 100, it can also be cleaned. At the same time, when the two rollers 105 move to the end section of the trough body 100 (the end section of the track groove 104 is a Z-shaped structure, so that the two rollers 105 are separated from the trough body 100), the hair roller 109 can be eccentrically swung, so that the impurities on the hair roller 109 can fall off due to centrifugal force.
