Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] In order to solve the current problem that the detection of podocyte disease mainly relies on kidney biopsy, which is invasive and complicated to operate, causing great pain to patients, and the operation process is complicated and requires professional medical personnel to perform; while urine-based podocyte detection avoids the trauma of biopsy, it usually requires cumbersome sample processing steps and professional laboratory equipment, which is not conducive to the rapid screening and diagnosis of the disease. Figure 1 , this embodiment provides the following technical solutions:

[0064] A device for quickly detecting podocytosis, comprising:

[0065] The sample collection and processing unit is used to obtain urine and blood samples actively submitted by patients for testing, and perform pretreatment to obtain pretreated target urine samples and target blood samples;

[0066] A marker detection unit, used to perform quantitative detection on the pretreated target urine sample and target blood sample, establish a marker standard curve, and obtain the marker concentration in the target urine sample and target blood sample based on the marker standard curve;

[0067] An analysis report generating unit is used for performing podocytosis analysis based on marker concentrations in a target urine sample and a target blood sample and generating a diagnosis report for the patient.

[0068] In this embodiment, the sample collection and processing unit includes:

[0069] The sample acquisition module is used to obtain urine and blood samples from patients and generate unique sample identification codes, match the unique sample identification codes with the patient's urine and blood samples one by one, and monitor the sample collection process, including checking whether the sampling container is sterile and whether the sampling operation complies with the standard process, etc., to ensure that the sample collection process complies with clinical specifications and avoids contamination;

[0070] The sample preprocessing module is used to identify and classify the acquired samples, obtain the patient's urine sample and blood sample, read the sample identification code, and process the urine sample and blood sample separately. Specifically:

[0071] The urine sample is placed in a centrifuge tube, and a centrifugal operation is performed according to the centrifugal parameters of the preset speed and centrifugal time to remove cells and particulate impurities in the urine;

[0072] Removing the sediment of the urine sample after centrifugation, retaining the supernatant, and extracting the podocyte marker in the supernatant using a suitable protein extraction method or kit;

[0073] Purifying and concentrating the extracted podocyte markers to remove non-target proteins and other impurities, and increasing the protein concentration by concentration to obtain a target urine sample;

[0074] The blood sample is placed in a centrifuge tube and centrifuged. The speed and time are set according to preset parameters, usually 1500-2000g, centrifuged for 10-15 minutes, to separate the plasma;

[0075] The upper plasma after centrifugation is taken out, and a protein extraction reagent (such as a protein extraction buffer) is added to the upper plasma, and the mixture is mixed thoroughly to dissolve the protein in the plasma;

[0076] The mixed mixture is centrifuged again, usually at 12000-16000 g for 10-20 minutes to precipitate the protein, the supernatant is removed, and the precipitated protein is extracted;

[0077] The extracted protein is purified and concentrated to remove non-target proteins and other impurities, and the protein concentration is increased through a concentration step to obtain a target blood sample.

[0078] In this embodiment, sample tracking is achieved through the generation and application of a unique sample identification code, ensuring the rigor of the detection process, pre-treating the sample to effectively remove impurities, and increasing the protein concentration, providing high-purity samples for subsequent marker detection, improving detection sensitivity and specificity, and reducing experimental errors, providing a reliable basis for the accurate diagnosis and treatment of podocyte injury, thereby helping to improve the treatment effect and quality of life of patients.

[0079] Specifically, the process of setting the rotation speed for centrifugal separation of the urine sample includes:

[0080] Extract sample volume and sample density;

[0081] Obtaining an adjustment coefficient according to the sample volume and the sample density;

[0082] The adjustment coefficient is obtained by the following formula:

[0083]

[0084] Wherein, K represents the adjustment coefficient; V represents the sample volume; S represents the sample density; D represents the diameter of the centrifuge tube; r represents the centrifugal radius of the centrifuge;

[0085] Extract centrifuge constants and centrifuge tube diameters;

[0086] The rotation speed is obtained by combining the adjustment coefficient with the centrifuge constant and the diameter of the centrifuge tube, wherein the rotation speed is obtained by the following formula:

[0087]

[0088] Among them, R represents the rotation speed; K represents the adjustment coefficient; V represents the sample volume; S represents the sample density; D represents the diameter of the centrifuge tube; r represents the centrifugal radius of the centrifuge; g represents the gravitational acceleration; w represents the centrifugal angular velocity; and R0 represents the preset initial rotation speed.

[0089] The technical effect of the above technical solution is: by extracting the volume (V) and density (S) of the sample, and combining the diameter (D) of the centrifuge tube and the centrifugal radius (r) of the centrifuge, the adjustment coefficient (K) is calculated. This adjustment coefficient takes into account the physical properties of the sample and the parameters of the centrifugal equipment, so that the subsequent speed setting is more in line with the actual needs of the sample. Using the adjustment coefficient (K), centrifuge constant, diameter of the centrifuge tube (D), sample volume (V), sample density (S), centrifugal radius of the centrifuge (r), gravitational acceleration (g) and centrifugal angular velocity (w) and other parameters, the speed (R) is calculated by formula. This calculation method takes into account multiple factors and helps to improve the accuracy of centrifugal separation.

[0090] By accurately calculating the rotation speed, it can be ensured that the centrifugal separation process is carried out under optimal conditions, thereby shortening the separation time and improving the separation efficiency. The preset initial rotation speed (R0) may be an optimized value based on experience or experimental data. Combined with fine-tuning of the adjustment coefficient, the high efficiency of centrifugal separation can be further ensured. This technical solution adapts to urine samples of different volumes and densities by calculating the adjustment coefficient, making the centrifugal separation process more flexible and universal. By adjusting the rotation speed, it can adapt to changes in different centrifuge tube diameters and centrifugal radii of the centrifuge, thereby enhancing the applicability of centrifugal separation. Through standardized calculation processes and parameter settings, it can be ensured that the conditions of each centrifugal separation experiment are as consistent as possible, thereby improving the repeatability and consistency of the experiment. This is crucial for scientific research, clinical diagnosis and other fields, and can ensure the accuracy and reliability of experimental results.

[0091] In summary, this technical solution improves the accuracy, efficiency, applicability, repeatability and consistency of centrifugal separation by accurately calculating the rotation speed and comprehensively considering the physical properties of the sample and the parameters of the centrifugal equipment. This has important technical significance and application value for the centrifugal separation of urine samples.

[0092] Specifically, the process of setting the centrifugal time for centrifugal separation of the urine sample includes:

[0093] Extract sample volume and sample density;

[0094] Extract adjustment coefficient and speed;

[0095] The centrifugation time is set using the sample volume and sample density in combination with the adjustment factor and the rotation speed;

[0096] Wherein, the centrifugation time is obtained by the following formula:

[0097]

[0098] Wherein, T represents the centrifugation time; T0 represents the preset initial centrifugation time; R represents the rotation speed; K represents the adjustment coefficient; V represents the sample volume; and S represents the sample density.

[0099] The technical effect of the above technical solution is: by extracting the volume (V) and density (S) of the sample, and combining the adjustment coefficient (K) and speed (R) calculated previously, the centrifugation time (T) can be customized. This setting method takes into account the specific physical properties of the sample and the operating parameters of the centrifugal device, so that the centrifugation process is more in line with the actual needs of the sample. By using the formula to calculate the centrifugation time, it can be ensured that the sample achieves the expected separation effect at the appropriate speed and adjustment coefficient. This helps to reduce unnecessary centrifugation time and improve separation efficiency. At the same time, by setting the centrifugation time accurately, it can be ensured that the different components in the sample are fully separated and the separation effect is improved. Through standardized calculation processes and parameter settings, it can be ensured that the conditions of each centrifugation experiment are as consistent as possible, thereby enhancing the controllability of centrifugation. In addition, since the centrifugation time is calculated by a formula, the centrifugation effect of different samples under different conditions can be predicted, which facilitates experimental design and data analysis. By ensuring that the conditions of each centrifugation experiment are consistent, the repeatability of the experiment can be improved. This is crucial for research that requires repeated experiments to verify the results. At the same time, consistent experimental conditions also help to improve the consistency of experimental results, so that experimental results between different batches or different laboratories can be compared and verified with each other. The centrifugal separation operation process can be simplified by calculating the centrifugal time through the formula. The experimenter only needs to input the basic information such as the volume and density of the sample, as well as the parameters of the centrifugal equipment (such as speed, adjustment coefficient, etc.), and the centrifugal time can be automatically calculated without the tedious trial and error and adjustment process.

[0100] In summary, this technical solution improves the customization, efficiency and effect, controllability and predictability, repeatability and consistency of centrifugal separation by accurately calculating the centrifugation time and comprehensively considering the physical properties of the sample and the parameters of the centrifugal equipment, and simplifies the operation process of centrifugal separation. This has important technical significance and application value for the centrifugal separation of urine samples.
