Description

Technical Field

[0001] The invention belongs to the field of medical technology, and in particular relates to an electrochemical detection kit and an automatic detection device thereof. Background Art

[0002] Sample testing is often used in the field of medical testing. Routine body fluid testing includes blood testing, urine testing, pleural and abdominal effusion testing, etc. Blood testing can clearly detect a variety of blood indicators such as hemoglobin levels, blood sugar, blood lipids, liver function, kidney function, platelet count and other blood indicators. Urine testing can detect indicators such as urine composition, urine enzymes, and urine protein composition. Pleural and abdominal effusion testing can detect indicators such as protein composition and white blood cell count. Body fluid testing can help doctors diagnose diseases and monitor health conditions.

[0003] Electrochemical detection is used in different fields including medical detection, environmental and gas detection, chemical production and other fields such as measuring blood sugar, active enzymes, sulfur dioxide concentration, etc. Electrochemical sensors can be designed in different styles for different application scenarios. They can be two-electrode or three-electrode, and can be potentiometers, voltammeters or ammeters. Some electrochemical detection sensors are based on organic matter and nano-accessories for detection.

[0004] Different detection indicators in the field of medical testing have different detection modes. According to different detection reagents and different detection bases, different pre-treatments are performed on the test samples. After the test, different equipment is used for post-processing to finally obtain the final detection parameters, which are used as the basis for clinical diagnosis. The essence of electrochemical detection is to convert identifiable features into current signals. There are currently various methods to modify electrochemical sensors. When the electrochemical sensor binds to the target, it will cause changes in the effective aperture of the channel, the inner surface charge, and the inner wall wettability, thereby causing changes in the ion current. The current detection device detects the change in the original current value, thereby detecting the corresponding indicators.

[0005] For general testing departments and institutions, different detection devices are generally configured, different pretreatments are performed according to different test samples, and the tests are performed on the corresponding detection devices. This method is suitable for departments or institutions with sufficient testing space. However, for general testing institutions, due to the small space and complicated pretreatment and testing processes, improper testing is likely to affect the testing efficiency and quality. Most of the existing electrochemical detection devices are single detection devices with complex detection processes and low detection rates, which are not suitable for large-scale electrochemical detection. Based on the above-mentioned electrochemical detection principles and application scenarios, it is necessary to design an electrochemical detection kit and its automatic detection device; the detection device has a high degree of integration, occupies less space, and has a high degree of automation in the pretreatment and detection processes, which is suitable for large-scale testing.

The automatic lifting device 17 is used to realize the operation of raising and lowering the automatic lifting platform, and the automatic lifting device 17 is located on the side of the three-layer platform. The above-mentioned detection units are arranged on the upper platform, the middle platform and the lower platform, and each platform realizes different functions respectively, vertically utilizing the effective space, and through the collaborative operation of different functional modules, the effective utilization of space is realized, and the degree of integration of the detection device is improved.

Through the automated and integrated electrochemical detection kit, the detection efficiency is improved and the amount of manual work is reduced.

[0038] See also Figure 1 and Figure 2 The loading device is located on the upper platform 16 and is provided with a guide rail 161 parallel to the X-axis. The electrochemical detection kit 1 can move forward and backward along the guide rail 161 in the X-axis direction to complete the loading operation. The upper platform 16 can place multiple electrochemical detection kits 1 in parallel, thereby achieving the effect of uninterrupted loading. The automatic lifting platform 12 can make a translational movement along the Y-axis under the traction of the automatic lifting device 17. The automatic lifting platform 12 includes a guide rail 121 parallel to the X-axis. The guide rail 121 is consistent with the upper platform guide rail 161. The electrochemical detection kit 1 can move to the guide rail 121 through the guide rail 161 and then reach the middle platform 14 and the lower platform 13 through the traction of the automatic lifting device 17. The electrochemical detection kit 1 can translate along the X-axis and Y-axis through the guide rails. The function of the guide rails is to transfer the electrochemical detection kit 1 to different workstations to complete operations of different processes. The design of the guide rail enables the device to achieve precise displacement and position control in different directions, thereby adapting to the position requirements of different process operations. Programming control of displacement and position can improve the accuracy of equipment operation and reduce errors compared to manual operation. The guide rail under programmed control can achieve multiple precise reciprocating movements, improve work efficiency, reduce human operation resources, improve the stability and accuracy of device operation, and improve overall operating efficiency.

[0039] It should be noted that the upper platform 16 can accommodate multiple electrochemical detection kits 1. The multiple electrochemical detection kits 1 are placed side by side and transported to the automatic lifting platform 12 in sequence through the guide rails, thereby increasing the detection efficiency.

[0040] See also Figure 1 , Figure 2 and Figure 3 , the middle platform 14 is located below the upper platform 16, and the middle platform 14 is provided with a guide rail 141 parallel to the X-axis and a Z-axis guide rail 21 located in the same plane as and perpendicular to the X-axis. The electrochemical detection kit 1 can be moved to the middle platform 14 via the automatic lifting platform 12 to complete the pretreatment process. The electrode detection device 2, the blood sample injection device 3, the sample kit 4, the sample detection encoding device 5 and the electrolyte injection and extraction device 15 are located on the middle platform 14. The electrochemical detection kit 1 first moves to the electrolyte injection and extraction device 15, and the electrolyte pipette injects electrolyte into the detection tank 16 of the electrochemical detection kit. After the injection is completed, the electrochemical detection kit 1 moves along the guide rail 141 to the electrode detection device 2, and the electrode detection connector of the electrode detection device 2 is inserted into the external electrode connector of the electrochemical detection kit 1 for detection. Figure 1The electrode probe 2 shown can perform translational movement along the guide rail 21 parallel to the Z axis, and the electrode detection connector of the electrode detection device 2 can fully cooperate with the external electrode connector of the electrochemical detection kit 1 to measure and record the initial current I0 passing through the sensor. After the measurement is completed, the electrochemical detection kit 1 moves along the guide rail 141 to the electrolyte injection and extraction device 15, and the electrolyte pipette extracts the electrolyte in the detection tank 16. After the extraction is completed, the electrochemical detection kit 1 moves along the guide rail 141 to the sample injection device 3, and the sample injection probe 32 can perform translational movement along the guide rail 31 parallel to the X axis, and can also perform translational movement along the lead screw parallel to the Z axis. The sample injection probe installs the pipette from the pipette installation device 42 of the sample reagent box 4, moves along the guide rail 31 to the top of the sample holding device 41 to be tested, and is translated to below the sample liquid surface by the lead screw to perform extraction operations. After the extraction is completed, it moves to the top of the detection slot of the electrochemical detection reagent box 1 to inject the sample into each detection slot respectively. After the injection is completed, it is translated along the guide rail 31 to the top of the waste disposal position 43 of the sample reagent box 1, and the pipette that completes the extraction and injection operations is discarded at the waste disposal position 43. The electrochemical detection reagent box 1 after the sample is injected moves along the guide rail 141 to the automatic lifting platform 12, and the automatic lifting platform 12 reaches the lower platform 13 under the traction of the automatic lifting device 17. After the sample reagent box 4 completes the sample extraction of all groups, it can be replaced with a new sample reagent box 4, and the pipette waste in the waste material discarding box 43 can be recycled or discarded. By setting a multi-degree-of-freedom sample injection probe to absorb and move samples, the accuracy of sample absorption is improved and the workload of staff is reduced. By integrating the pipette installation device 42, the waste material discarding box 43 and the sample containing device 41 into the sample reagent box 4, the space utilization rate of the device is improved, and the integrated sample reagent box 4 facilitates the collection of discarded pipettes. The process of sucking samples, injecting samples and discarding pipettes can be realized by only translating along the X-axis 31 guide rail and translating along the Z-axis lead screw 32. The programming and operation during use are relatively simple, and there are many applicable scenarios, which improves the degree of automation of detection.

[0041] It should be noted that the sample detection encoding device 5 can enter the patient's basic information into the detection system by scanning the barcode attached to the sample test tube. The basic information includes: the patient's age, gender, name, sample collection time, sample collection source, patient's medical history, sample test items, etc. Registering the patient's basic information by scanning the barcode increases the efficiency and accuracy of information entry compared to traditional manual registration.

The cleaning device 10 and the drainage device 8 are located in the same vertical plane, and the drainage device 8 is located below the lower platform. The drainage probe 81 of the drainage device 8 first passes through the circular hole of the lower platform and is inserted into the drainage channel 12 of the electrochemical detection kit. The curved surface of the drainage probe 81 can perfectly match the curved surface of the drainage channel, ensuring the sealing during drainage. The drainage probe 81 sucks the tested sample into the drainage channel 12 by applying negative pressure, and discharges it through the drainage conduit 82 connected to the outside. After the sample is discharged, the cleaning probe of the cleaning device 10 goes deep into the detection tank along the gas path parallel to the Y axis and injects purified water. The ultrasonic probes installed side by side apply ultrasonic waves to the purified water in the detection tank to achieve the cleaning effect. After the cleaning is completed, the drainage device 8 is started again to suck the waste water in the detection tank after cleaning into the external conduit 82 for discharge. After the discharge is completed, the electrochemical detection kit 1 moves along the guide rail 131 to the electrolyte injection device 9, and the electrolyte injection device 9 is inserted into the detection tank along the gas path parallel to the Y axis to inject electrolyte. After the electrolyte is injected, the electrode secondary detection device 6 is inserted into the external electrode connector of the electrochemical detection kit 1 along the guide rail 61 parallel to the Z axis, and the electrical signal I1 is detected and recorded. The required detection index can be obtained by comparing the electrical signals I1 and I0, and finally the electrochemical detection kit 1 after detection is thrown into the waste collection box 7.

[0043] The waste collection box 7 is located below one side of the lower platform 13. After moving to the end via the guide rail 131, it falls into the waste collection box 7, which improves the operating efficiency of the device and can collect waste without manual operation, avoiding possible pollution and the like, thereby enhancing the safety of the device. The drainage probe extracts waste liquid from the bottom, which saves space in the device and avoids possible leakage and the like. The ultrasonic probe of the cleaning device 10 can release ultrasonic waves to achieve a better cleaning effect. A circuit and air path control device 11 is provided below the lower platform.
