Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This invention provides a convenient C-reactive protein and serum amyloid A combined detection kit, comprising a carrier container 100, a sample processing component 200, a detection card component 300, and a waste collection component 400. The sample processing component 200, the detection card component 300, and the waste collection component 400 are all placed inside the carrier container 100. The sample processing component 200 is used to preprocess the collected samples, including sample dilution and mixing operations; the detection card component 300 is used to perform detection processing on the preprocessed samples; and the waste collection component 400 is used to collect waste generated during the detection process.

[0026] The carrier container 100 includes a reagent kit body 110. A lid A120 is hinged to one side of the reagent kit body 110. The side of the reagent kit body 110 away from the hinge is detachably connected to the lid A120 by a snap-fit. A support block 130 is fixedly connected to the inner cavity of the reagent kit body 110. The height of the support block 130 is lower than the height of the inner cavity of the reagent kit body 110. The sample processing component 200, the test card component 300, and the waste collection component 400 are respectively placed on the support block 130. The carrier container 100 can fix the sample processing component. The component 200, test card component 300, waste collection component 400, and quality control sample bottle 500 integrate sample pretreatment, testing, and waste collection functions into one unit, realizing a "one-stop" testing process. It is convenient for medical staff or testing personnel to carry the test kits and is suitable for mobile scenarios such as primary medical institutions, emergency rooms, or rapid on-site testing. It provides crush-resistant and impact-resistant physical protection for fragile components such as the internal C-reactive protein test card 310, serum amyloid A test card 320, and quality control sample bottle 500 to avoid damage during transportation.

[0027] The main body of the reagent kit 110 is fixed to a handle 140 on the side near the buckle and rotates via a pivot. The top of the lid A120 is fixedly connected to a label 150 with detailed instructions on the testing steps and precautions. The handle 140 makes it easy for medical staff or testing personnel to carry the reagent kit, making it suitable for mobile scenarios such as primary healthcare institutions, emergency rooms, or rapid on-site testing. The label 150 lowers the operational threshold and ensures that non-professionals can also complete the testing according to the specifications.

[0028] The sample processing component 200 includes a sample dilution cup 210, a stirring rod 220, and a sample transfer pipette 230, all located within the inner cavity of the reagent kit body 110 and away from the snap-fit. The sample dilution cup 210 is used to accurately measure the sample and diluent, the stirring rod 220 is used to mix the sample and diluent, and the sample transfer pipette 230 is used to transfer the uniformly mixed sample onto the detection card component 300. The support block 130 has a groove A131 that matches the sample dilution cup 210, a groove B132 that matches the stirring rod 220, and a groove C133 that matches the sample transfer pipette 230. The sample dilution cup 210 is snapped into groove A131, the stirring rod 220 into groove B132, and the sample transfer pipette 230 into groove C133. The sample processing component 200 can preprocess the collected sample to ensure the accuracy and reliability of subsequent testing.

[0029] The sample dilution cup 210 includes a cup body 211 with graduation markings. A cup lid 212 is threaded onto the mouth of the cup body 211. The cup lid 212 has a through hole 213 for the stirring rod 220 to pass through. By using the cup body 211 in conjunction with the graduation markings, the sample and diluent can be accurately measured. By using the cup lid 212 in conjunction with the through hole 213, the sample can be prevented from splashing or evaporating during stirring, thus maintaining the integrity and stability of the sample and reducing pollution to the testing environment.

[0030] The test card assembly 300 includes a C-reactive protein test card 310 and a serum amyloid A test card 320 located in the inner cavity of the main body 110 of the reagent kit near the snap fastener. Both the C-reactive protein test card 310 and the serum amyloid A test card 320 are mounted on the support block 130. By using the C-reactive protein test card 310 and the serum amyloid A test card 320 together, the pre-treated sample can be tested to obtain the detection results of C-reactive protein (CRP) and serum amyloid A (SAA) respectively, so as to realize the joint detection of the two inflammatory markers, thereby providing an important basis for the early diagnosis, disease monitoring and efficacy evaluation of infectious diseases.

[0031] The test card assembly 300 also includes a card holder 330. The C-reactive protein test card 310 and the serum amyloid A test card 320 are arranged side by side in the card slots of the card holder 330. The top of the support block 130 has a groove D134 that is adapted to the card holder 330. The card holder 330 is fixedly connected in the groove D134. The card holder 330 can prevent the C-reactive protein test card 310 and the serum amyloid A test card 320 from shifting during transportation and use.

[0032] The waste collection component 400 includes a collection box 410 and a lid B420 located inside the main body 110 of the reagent kit. The collection box 410 is adjacent to the sample transfer pipette 230 and the holder 330. One side of the collection box 410 is hinged to the lid B420, and the side of the collection box 410 away from the hinge is fastened with a snap fastener. The support block 130 has a groove E135 that matches the collection box 410. The collection box 410 is engaged in the groove E135, and the waste is collected within the collection box. The storage component 400 can store waste generated during the testing process. The inner cavity of the storage box 410 is integrally formed with a partition 411, which is used to divide the inner cavity of the storage box 410 into two storage areas. Different areas can be used to classify and store waste. One storage area can store the used sample processing component 200, and the other storage area can store the C-reactive protein test card 310 and serum amyloid A test card 320 after the test is completed, which are isolated from the sample processing component 200 to avoid cross-contamination.

[0033] The hinges of lids B420 and A120 are perpendicular to each other. The hinge of lid B420 is close to the inner wall of the reagent kit body 110, which can maximize the opening of lids A120 and B420 while preventing lid B420 from obstructing the sample processing component 200 and waste collection component 400 after opening. Both lids B420 and A120 have sealing strips on their edges. When lids B420 and A120 are closed, the waste collection component 400 and the carrier container 100 can be sealed, preventing the leakage of harmful substances and the emission of odors from the waste in the waste collection component 400. The carrier container 100 in the closed state can isolate external environmental factors such as dust and moisture, maintaining the stability of its internal test card components 300 (such as the activity of C-reactive protein test card 310 and serum amyloid A test card 320 is not affected by moisture).

[0034] The system also includes a quality control sample bottle 500 positioned opposite the sample dilution cup 210. The quality control sample bottle 500 contains quality control samples of known concentrations of C-reactive protein and serum amyloid A. A groove F136 adapted to the quality control sample bottle 500 is provided on the support block 130. The quality control sample bottle 500 is inserted into the groove F136. The quality control sample bottle 500 is used to control the quality of the testing process and ensure the accuracy of the test results. 137 is provided on both sides of the inner cavity of grooves A131, B132, C133 and F136. The 137 facilitates the handling of the sample dilution cup 210, stirring rod 220, sample transfer pipette 230 and quality control sample bottle 500 by fingers.

[0035] The working principle of this utility model is as follows: First, open the lid A120, take out the sample processing component 200, unscrew the cup lid 212, place the collected sample into the cup body 211, accurately measure an appropriate amount of diluent according to the scale markings on the cup body 211, add it to the cup body 211, tighten the cup lid 212, and then pass the stirring rod 220 through the through hole 213 to stir within the cup body 211 to mix the sample and diluent, ensuring the sample is fully diluted and homogeneous. The physical shielding of the cup lid 212 and the tight fit between the through hole 213 and the stirring rod 220 maintain a relatively closed environment within the cup body 211 during dynamic operation, effectively controlling sample splashing and evaporation. After stirring, unscrew the through hole 213 and use the sample transfer pipette 230 to transfer the homogeneous sample to the sample application wells of the C-reactive protein detection card 310 and the serum amyloid A detection card 320. Inside, samples can be tested separately using the C-reactive protein test card 310 and the serum amyloid A test card 320. During the testing process, used sample processing tools such as sample transfer pipettes 230 and stirring rods 220, as well as waste such as the C-reactive protein test card 310 and the serum amyloid A test card 320 after testing, can be placed in the corresponding storage area of ​​the storage box 410. After testing, the box lid B420 is closed to seal the storage box 410 and ensure safety. At the same time, the quality control sample in the quality control sample bottle 500 can be used to control the quality of the testing process as needed. Open the cap of the quality control sample bottle 500, take out the quality control sample, and test according to the above testing steps (the step of transferring the sample to the sample well). The test results are compared with the known concentration of the quality control sample to determine the accuracy and reliability of the entire testing process.

[0036] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
