The conveying device includes a frame with multiple sets of test tube racks. A pushing mechanism can reciprocate between a first conveying position and a second conveying position. A stop is movably connected to the frame, and a pusher is movably connected to the pushing mechanism. When the pushing mechanism is in the first conveying position, the pusher and the stop are separated. When the pushing mechanism is in the second conveying position, the pusher and the stop abut against each other. The problem solved is that in the prior art, the stop and the pushing mechanism are mostly controlled by two independent drive devices.

Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and more specifically, to a fully automated biochemical analyzer and its detection method. Background Technology

[0002] As a core testing device in clinical testing, biomedical research, and medical detection, fully automated biochemical analyzers are widely used for the detection of biochemical indicators in various samples such as blood and urine, thanks to their advantages of high efficiency, accuracy, and automation. This significantly reduces the intensity of manual operation and improves testing efficiency and the stability of test results.

[0003] As the medical industry continues to demand higher testing efficiency, accuracy, and stability of equipment operation, the overall structural design of fully automated biochemical analyzers is constantly being optimized. Currently, most fully automated biochemical analyzers on the market are equipped with sample transport devices, which are used to transport test tube racks containing test samples in an orderly manner to a track device, and then the track device transfers them to the analytical device to complete the testing operation. The sample transport device in the existing technology usually includes a frame, a pushing mechanism, and a stop. The frame is used to store test tube racks in batches, the pushing mechanism can move back and forth between the track device and the frame to realize the handling and transmission of test tube racks, and the stop is used to prevent the test tube racks from accidentally slipping off the frame.

[0004] However, the relevant technologies have at least one of the following problems: In the existing technology, the stop and push mechanism of the automatic biochemical analyzer are mostly controlled by two independent drive devices. During operation, when the push mechanism pushes the test tube rack, the stop may not avoid it in time and may still be in the blocking state, resulting in a hard collision and squeezing between the test tube rack and the stop. This causes the stop to deform and wear, shorten its service life, and then cause the test tube rack to shift and the sample to spill, affecting the continuity and stability of the detection process. Summary of the Invention

[0005] The technical problem solved by this invention is that in the prior art, the stop and push mechanism of automated biochemical analyzers are mostly controlled by two independent drive devices. During operation, when the push mechanism pushes the test tube rack, the stop may not avoid it in time and may still be in a blocking state, resulting in a hard collision and squeezing between the test tube rack and the stop. This causes the stop to deform and wear, shorten its service life, and then leads to problems such as test tube rack displacement and sample leakage, affecting the continuity and stability of the detection process.

[0006] To address the above problems, the present invention provides a fully automated biochemical analyzer, which includes an analytical device, a track device for transporting samples to the analytical device, and a transport device connected to the sample inlet end of the track device. The conveying device includes: The rack is equipped with multiple test tube racks for storing samples; The pushing mechanism is capable of reciprocating between a first conveying position near the sample inlet and a second conveying position near the frame. Stop component, which is movably connected to the frame; The jacking component is movably connected to the pushing mechanism. When the pushing mechanism is in the first conveying position, the end of the pushing member near the frame separates from the stop member, and the stop member restricts the test tube rack from sliding off the frame. When the pushing mechanism is in the second conveying position, the end of the pushing member near the frame abuts against the stop member, and the stop member avoids the test tube rack.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution achieves synchronous control of the test tube rack pushing and the stop component avoiding by a single drive device through the linkage structure of the pushing mechanism, the pushing component, and the stop component. Structurally, it ensures precise matching of action sequence, avoids hard collision and squeezing between the test tube rack and the stop component, reduces deformation and wear of the stop component, extends its service life, and prevents test tube rack displacement and sample spillage, effectively improving the continuity, stability, and reliability of sample transportation and testing processes.

[0008] Specifically, when the pushing mechanism is at the first conveying position, the pushing component and the stop component separate, and the stop component blocks the test tube rack by its own limiting action. As the pushing mechanism moves to the second conveying position, the pushing component simultaneously approaches and pushes against the stop component, ensuring that the stop component completes its avoidance action before the pushing mechanism reaches its final position. This direct mechanical displacement linkage eliminates the need for electrical control signals, sensors, or additional drive devices, ensuring the timing of the pushing and avoidance actions is synchronized. This avoids situations where the stop component fails to avoid the test tube rack in time and remains in an obstructive state, thus reducing deformation and wear of the stop component and extending its service life. Similarly, the timely avoidance by the stop component prevents the test tube rack from shifting, preventing sample spillage and improving the continuity, stability, and reliability of the sample transport and testing process.

[0009] In one embodiment of the present invention, an elastic element is provided between the pushing mechanism and the jacking member; The pushing mechanism is provided with a connecting part, and the pushing component is provided with a connecting lug; One end of the elastic element is connected to the connecting part, and the other end is connected to the connecting ear; When the pushing mechanism is in the first conveying position, the elastic element is in a stretched state; when the pushing mechanism is in the second conveying position, the elastic element returns to its initial state.

[0010] Compared with existing technologies, the technical effects achieved by this solution are as follows: By adding an elastic element between the pushing mechanism and the pushing component, the deformation and reset of the elastic element are used to achieve the linkage between the pushing mechanism and the pushing component. This ensures that the pushing component and the stop component have smooth and reliable contact and separation actions, avoids rigid impact, and further improves the stability of the test tube rack during the pushing process. At the same time, it ensures that the stop component avoids and resets in a timely and accurate manner, thereby reducing component wear and failure risk, improving the reliability of the sample transport process and the service life of the fully automated biochemical analyzer.

[0011] In one embodiment of the present invention, the pushing mechanism is provided with a pushing rod, and the end of the pushing member near the sample inlet is provided with a bent portion; When the pushing mechanism is in the first transmission position, the end of the pushing rod near the sample inlet abuts against the bent part; when the pushing mechanism is in the second transmission position, the end of the pushing rod near the sample inlet separates from the bent part.

[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution forms a mechanical triggering and follow-up control structure through the abutment and separation of the push rod and the bent part on the pusher. Specifically, when the push mechanism is in the first transmission position, the push rod abuts against the bent part, providing positioning and attitude constraints for the pusher, ensuring its stable position. During the movement of the push mechanism to the second transmission position, the push rod separates from the bent part in a timely manner, allowing the pusher to move smoothly towards the stop under the action of the elastic element, and enabling the stop to complete the avoidance action. This achieves mechanical linkage between the push mechanism and the pusher, ensuring stable and reliable timing and timely response of the pusher and stop actions, further optimizing the avoidance and reset control of the stop, and improving the overall coordination and operational stability of the fully automated biochemical analyzer.

[0013] In one embodiment of the present invention, the track device further includes a sample outlet disposed opposite to the sample inlet end, and the track device includes: The first conveying track, at least one of which is used for conveying samples; The second conveyor track, which is set parallel to the first conveyor track, is used to transport the sample after testing to the rack. The transfer track is located at the sample outlet and moves back and forth between the first and second transport tracks to transfer the tested sample to the second transport track.

[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution solves the problems of low sample transport efficiency and poor connection between detection and return in existing technologies by using parallel first and second transport tracks and setting up a reciprocating transfer track to form a closed-loop sample flow structure. Simultaneously, the reciprocating linkage structure of the transfer tracks enables the transfer of samples to the second transport track after detection, avoiding sample transfer deviation and jamming, and improving transport reliability and connection smoothness. The second transport track enables automated return of samples to the rack after detection, eliminating the need for additional drive mechanisms or manual operation, simplifying the overall structure, reducing energy consumption and component wear, and thus improving the continuity and stability of the sample transport and detection process of the fully automated biochemical analyzer.

[0015] In one embodiment of the present invention, a temporary storage position and a first detection position are sequentially provided along the first conveying track from the sample inlet end to the sample outlet end; The track device also includes a first stop component and a second stop component arranged sequentially from the sample inlet end to the sample outlet end; The first stop component is used to stop the test tube rack at the temporary storage position, and the second stop component is used to stop the test tube rack at the first detection position.

[0016] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting a first stop component and a second stop component on the first conveying track, this solution achieves precise positioning and orderly control of the test tube rack at the temporary storage position and the first detection position, solving the problems of misalignment of the test tube rack and positioning deviation of the detection position in existing technologies, and further improving the stability and orderliness of the track device operation.

[0017] Specifically, firstly, the first stop component stops the test tube rack at the temporary storage position, achieving orderly buffering of samples and preventing congestion at the sample entry end. This ensures a smooth transition to subsequent testing stations and improves the continuity of sample delivery. Secondly, the second stop component stops the test tube rack at the first testing position, ensuring that the test tube rack on the first delivery track can be accurately positioned at the testing station, guaranteeing the accuracy of sample testing and preventing positioning deviations from affecting test results.

[0018] In one embodiment of the invention, the track device further includes a support for supporting the first transport track and the second transport track; The first stop component includes: The first drive assembly is disposed on the support and located at the bottom of the first conveying track; The first stop component is connected to the first drive component; The first side plate of the first conveying track is provided with a first clearance groove for avoiding the first stop member, and the first drive assembly is used to drive the first stop member to reciprocate between the temporary storage position and the first clearance groove. The second stop component includes: The second drive assembly is disposed on the support and located at the bottom of the first conveying track; The second stop component is connected to the second drive assembly; The first side plate has a second clearance groove for avoiding the second stop member, and the second drive assembly is used to drive the second stop member to reciprocate between the first detection position and the second clearance groove.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution integrates the first and second stop components on the bottom support of the conveyor track, and controls the avoidance actions of the first and second stop components through the first and second drive components respectively. This avoids the situation where the first and second stop components fail to avoid the test tube rack in time and cause hard collisions and squeezing, reduces the deformation and wear of the first and second stop components, extends their service life, and prevents the test tube rack from shifting and sample spillage, thus ensuring the continuity and stability of the test tube conveying and testing process.

[0020] In one embodiment of the present invention, the analysis apparatus includes: Base; The reaction plate is located in the middle of the base, and multiple reaction cups are arranged in a ring inside the reaction plate; The output end of the reaction disk drive module is connected to the reaction disk to drive the reaction disk to rotate. The detection module is located on the outside of the reaction vessel and is used to detect the components of the solution inside the reaction vessel. The sample filling module is used to fill the first or second sample into the reaction vessel and achieve self-cleaning. The reagent dispensing module includes a first reagent dispensing unit and a second reagent dispensing unit, which are used to dispensing and cleaning reagents. The stirring and mixing module includes a first stirring unit and a second stirring unit, which are used to stir and mix the sample solution and reagent solution in the reaction vessel. The cleaning mechanism is used for cleaning the reaction cups by injecting and draining liquids. The liquid path module is connected to the sample dispensing module, reagent dispensing module, stirring and mixing module, and cleaning mechanism, respectively, and is used for liquid path delivery during the reaction; The sample dispensing module, reagent dispensing module, stirring and mixing module, and cleaning mechanism are arranged sequentially along the rotation direction of the reaction plate, while the liquid path module is located at the bottom of the base.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: By rationally arranging the sample dispensing module, reagent dispensing module, mixing module, and cleaning mechanism along the rotation direction of the reaction plate, and integrating the liquid path module at the bottom of the base, this solution improves the space utilization of the fully automated biochemical analyzer and realizes a streamlined and integrated operation of sample dispensing, reagent dispensing, mixing, reaction detection, and reaction cup cleaning. At the same time, by setting up self-cleaning and independent cleaning mechanisms, it improves sample detection efficiency and accuracy, and ensures a stable and reliable detection process.

[0022] To address the aforementioned technical problems, the present invention also provides a detection method for a fully automated biochemical analyzer. The detection method is applied to a fully automated biochemical analyzer as described in any of the above examples, and includes the following steps: S1. System power-on initialization, control each mechanism to reset to the initial state; S2. The control conveying device pushes multiple sets of test tube racks on the frame sequentially to the temporary storage position or the first detection position of the first conveying track; S3. The control and analysis device sequentially executes the reaction cup cleaning, sample addition, reagent addition, stirring and mixing, and component detection process; S4. After the test is completed, control the transfer track to transfer the test tube rack to the second transfer track and return it to the rack; S5. Repeat steps S2 to S4 until all samples are tested, then the control system is reset and enters standby mode. When each mechanism is reset to its initial state: the pushing mechanism is located in the first transmission position, the pusher and the stop are separated from each other and the stop restricts the test tube rack from sliding off the frame, the pushing rod and the pusher abut against each other, the elastic element is in a stretched state, the first stop is located in the first clearance groove, the second stop is located in the second clearance groove, each module of the analysis device is on standby and the liquid circuit module is ready.

[0023] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: This solution can achieve the technical effects corresponding to any of the technical solutions in the above examples, which will not be elaborated here.

[0024] In one embodiment of the present invention, step S2, the control process for the delivery device to push the test tube rack and reset includes: S21. Control the pushing mechanism to move from the first conveying position to the second conveying position, so that the end of the pusher near the frame abuts against the stop, drive the stop to avoid the test tube rack, and push the pusher rod to push the test tube rack from the frame to the sample inlet end of the track device. At the same time, the elastic element returns from the stretched state to the initial state. S22. After the test tube rack is sent into the first conveying track, the control push mechanism returns from the second conveying position to the first conveying position, so that the pusher and the stop are separated from each other, the stop is reset and the test tube rack is restricted from sliding off the frame.

[0025] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: This solution can achieve the technical effects corresponding to any of the technical solutions in the above examples, which will not be elaborated here.

[0026] In one embodiment of the present invention, step S2 further includes positioning control of the track device, specifically including the following steps: After the test tube rack enters the first conveying track, the first stop component is controlled to move to the temporary storage position to stop the test tube rack at the temporary storage position; When testing is required, the first stop component is controlled to move into the first clearance groove, the first conveying track will transport the test tube rack to the first testing position, and the second stop component is controlled to move into the first testing position to stop the test tube rack at the first testing position. Step S4 also includes the recovery control of the orbital device, specifically including the following steps: After the sample testing at the first testing position is completed, the control transfer track moves to the sample outlet end of the first conveying track, while the control of the second stop component avoids the sample, and the test tube rack that has completed the testing is transported to the transfer track. Then, the test tube rack is transferred to the second conveying track and returned to the rack via the transfer track.

[0027] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: This solution can achieve the technical effects corresponding to any of the technical solutions in the above examples, which will not be elaborated here.

[0028] By adopting the technical solution of the present invention, the following technical effects can be achieved: This invention achieves synchronous control of the test tube rack pushing and the stop component by a single drive device through the linkage structure of the pushing mechanism, the pushing component, and the stop component. The structure ensures precise matching of the action sequence, avoids hard collision and squeezing between the test tube rack and the stop component, reduces deformation and wear of the stop component, extends its service life, and prevents test tube rack displacement and sample leakage. This effectively improves the continuity, stability and reliability of the sample delivery and testing process.

[0029] Specifically, when the pushing mechanism is at the first conveying position, the pushing component and the stop component separate, and the stop component blocks the test tube rack by its own limiting action. As the pushing mechanism moves to the second conveying position, the pushing component simultaneously approaches and pushes against the stop component, ensuring that the stop component completes its avoidance action before the pushing mechanism reaches its final position. This direct mechanical displacement linkage eliminates the need for electrical control signals, sensors, or additional drive devices, ensuring the timing of the pushing and avoidance actions is synchronized. This avoids situations where the stop component fails to avoid the test tube rack in time and remains in an obstructive state, thus reducing deformation and wear of the stop component and extending its service life. Similarly, the timely avoidance by the stop component prevents the test tube rack from shifting, preventing sample spillage and improving the continuity, stability, and reliability of the sample transport and testing process.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 9 As shown, the present invention provides a fully automated biochemical analyzer, which includes an analysis device 100, a track device 200 for transporting samples to the analysis device 100, and a transport device 300 connected to the sample inlet end 210 of the track device 200; the transport device 300 includes a frame 310, a pushing mechanism 320, a stop member 311, and a pusher member 330. Specifically, the frame 310 is provided with multiple sets of test tube racks 400 for storing samples. The pushing mechanism 320 can reciprocate between a first conveying position near the sample inlet 210 and a second conveying position near the frame 310. The stop member 311 is movably connected to the frame 310, and the push member 330 is movably connected to the pushing mechanism 320. When the pushing mechanism 320 is in the first conveying position, the end of the push member 330 near the frame 310 is separated from the stop member 311, and the stop member 311 restricts the test tube rack 400 from sliding off the frame 310. When the pushing mechanism 320 is in the second conveying position, the end of the push member 330 near the frame 310 abuts against the stop member 311, and the stop member 311 avoids the test tube rack 400.

[0034] Understandably, this solution, through the linkage structure of the pushing mechanism 320, the pushing component 330, and the stop component 311, enables a single set of drive devices to synchronously control the pushing of the test tube rack 400 and the avoidance of the stop component 311. Structurally, this ensures precise matching of action timing, avoids hard collisions and squeezing between the test tube rack 400 and the stop component 311, reduces deformation and wear of the stop component 311, extends its service life, and prevents the test tube rack 400 from shifting and sample spillage. This effectively improves the continuity, stability, and reliability of sample delivery and testing processes.

[0035] Specifically, when the pushing mechanism 320 is in the first conveying position, the pushing member 330 separates from the stop member 311, and the stop member 311 blocks the test tube rack 400 by its own limiting effect. During the process of the pushing mechanism 320 moving to the second conveying position, the pushing member 330 simultaneously approaches and pushes the stop member 311, so that the stop member 311 completes the avoidance action before the pushing mechanism 320 is in place. It relies on direct linkage of mechanical displacement, without the participation of electrical control signals, sensors or additional driving devices, to ensure the timing synchronization of the pushing action and the avoidance action. This avoids the situation where the stop member 311 is not avoiding in time and is still in the blocking state when the pushing mechanism 320 pushes the test tube rack 400, thereby reducing the deformation and wear of the stop member 311 and extending the service life of the stop member 311. Similarly, it is understandable that when the pushing mechanism 320 pushes the test tube rack 400, the stop 311 can avoid it in time, thereby preventing the test tube rack 400 from shifting, preventing sample spillage, and improving the continuity, stability and reliability of the sample transportation and testing process.

[0036] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, an elastic member 340 is provided between the pushing mechanism 320 and the pushing member 330; the pushing mechanism 320 is provided with a connecting portion 321, and the pushing member 330 is provided with a connecting ear 331; wherein, one end of the elastic member 340 is connected to the connecting portion 321, and the other end is connected to the connecting ear 331; when the pushing mechanism 320 is in the first conveying position, the elastic member 340 is in a stretched state, and when the pushing mechanism 320 is in the second conveying position, the elastic member 340 returns to its initial state.

[0037] Understandably, this solution adds an elastic element 340 between the pushing mechanism 320 and the pushing component 330. The deformation and reset of the elastic element 340 enable the linkage between the pushing mechanism 320 and the pushing component 330, ensuring that the pushing component 330 and the stop component 311 abut and separate smoothly and reliably, avoiding rigid impact, and further improving the stability of the test tube rack 400 during the pushing process. At the same time, it ensures that the stop component 311 avoids and resets in a timely and accurate manner, thereby reducing component wear and failure risk, improving the reliability of the sample transport process and the service life of the fully automated biochemical analyzer.

[0038] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the pushing mechanism 320 is provided with a pushing rod 322, and the end of the pushing member 330 near the sample inlet 210 is provided with a bent portion 332; wherein, when the pushing mechanism 320 is located in the first conveying position, the end of the pushing rod 322 near the sample inlet 210 abuts against the bent portion 332; when the pushing mechanism 320 is located in the second conveying position, the end of the pushing rod 322 near the sample inlet 210 is separated from the bent portion 332.

[0039] Understandably, this solution forms a mechanical triggering and follow-up control structure through the abutment and separation of the push rod 322 and the bent part 332 on the push member 330. Specifically, when the push mechanism 320 is in the first transmission position, the push rod 322 abuts against the bent part 332, forming a positioning and attitude constraint on the push member 330, ensuring the stability of the push member 330's position. During the process of the push mechanism 320 moving to the second transmission position, the push rod 322 and the bent part 332 separate in a timely manner, allowing the push member 330 to move smoothly towards the stop member 311 under the action of the elastic member 340, and causing the stop member 311 to complete the avoidance action. This enables mechanical linkage between the pushing mechanism 320 and the pushing component 330, ensuring stable and reliable timing and timely response of the actions of the pushing component 330 and the stop component 311. It further optimizes the avoidance and reset control of the stop component 311, and improves the overall coordination and operational stability of the fully automated biochemical analyzer.

[0040] like Figure 5 As shown, in this embodiment, the pushing mechanism 320 further includes a lifting drive mechanism for driving the pushing rod 322 to rise and fall, and a conveyor belt 350 for driving the pushing rod 322 and the lifting drive mechanism to reciprocate synchronously. A connecting frame 360 ​​is fixedly provided on the conveyor belt 350, and the lifting drive mechanism is installed on the connecting frame 360. In this embodiment, the lifting drive mechanism adopts a gear 370 and rack 380 transmission form. The drive motor (not shown in the figure) is fixed to the connecting frame 360. The gear 370 is installed on the output shaft of the motor 393. The rack 380 is fixedly connected to the pushing rod 322, and the pushing rod 322 slides in cooperation with the connecting frame 360. The drive motor (not shown in the figure) drives the gear 370 to rotate. The rotational motion is converted into linear motion through the meshing of the gear 370 and the rack 380, thereby realizing the lifting action of the pushing rod 322.

[0041] like Figures 4 to 8As shown, in this embodiment, multiple test tube racks 400 can be placed on the frame 310, and the multiple test tube racks 400 are arranged side by side. The pushing mechanism 320 is driven by the sliding drive mechanism 390 at its bottom, so as to take out the test tube rack 400 at any position on the frame 310 and push it to the first conveying track 230, or to transfer the test tube rack 400 that has completed testing on the second conveying track 240 and place it on the frame 310. The sliding drive mechanism 390 consists of a slidingly engaged slider 391 and a slide rail 392, and a motor 393. In use, the motor 393 can drive the slider 391 to move back and forth along the slide rail 392, thereby driving the entire pushing mechanism 320 to move.

[0042] like Figures 1 to 7 As shown, in some embodiments of the present invention, the track device 200 further includes a sample outlet 220 disposed opposite to the sample inlet 210. The track device 200 includes a first conveying track 230, a second conveying track 240, and a transfer track 250. Specifically, there is at least one first conveying track 230 for conveying samples; the second conveying track 240 is disposed parallel to the first conveying track 230 for conveying the sample after testing to the frame 310; the transfer track 250 is located at the sample outlet 220, and the transfer track 250 reciprocates between the first conveying track 230 and the second conveying track 240 to transfer the sample after testing to the second conveying track 240.

[0043] Understandably, this solution solves the problems of low sample transport efficiency and poor connection between detection and return in the prior art by using parallel arrangement of the first transport track 230 and setting up a reciprocating transfer track 250 to form a closed-loop sample flow structure. Simultaneously, the reciprocating linkage structure of the transfer track 250 enables the transfer of samples to the second transport track 240 after detection, avoiding sample transfer deviation and jamming, and improving transfer reliability and connection smoothness. The second transport track 240 enables automated return of samples to the frame 310 after detection, eliminating the need for additional drive mechanisms or manual operation, simplifying the overall structure, reducing energy consumption and component wear, and thus improving the continuity and stability of the sample transport and detection process of the fully automated biochemical analyzer.

[0044] like Figures 1 to 7 As shown, in some embodiments of the present invention, a first conveying track 230 is provided with a temporary storage position 231 and a first detection position 232 sequentially from the sample inlet end 210 to the sample outlet end 220; the track device 200 also includes a first stop component and a second stop component sequentially arranged from the sample inlet end 210 to the sample outlet end 220; wherein, the first stop component is used to stop the test tube rack 400 at the temporary storage position 231, and the second stop component is used to stop the test tube rack 400 at the first detection position 232.

[0045] Understandably, this solution achieves precise positioning and orderly control of the test tube rack 400 at the temporary storage position 231 and the first detection position 232 by setting a first stop component and a second stop component on the first conveying track 230. This solves the problems of misalignment of the test tube rack 400 during conveying and positioning deviation of the detection position in the prior art, and further improves the stability and orderliness of the track device 200 operation.

[0046] Specifically, firstly, the first stop component stops the test tube rack 400 at the temporary storage position 231, achieving orderly sample buffering and preventing congestion of the test tube rack 400 at the sample entry end 210. This ensures the orderly connection of subsequent testing stations and improves the continuity of sample delivery. Secondly, the second stop component stops the test tube rack 400 at the first testing position 232, ensuring that the test tube rack 400 on the first transport track 230 can be accurately positioned at the testing station, guaranteeing the accuracy of sample testing and avoiding the impact of positioning deviations on test results.

[0047] like Figures 1 to 7 As shown, in some embodiments of the present invention, the track device 200 further includes a support 260 for supporting the first conveying track 230 and the second conveying track 240; the first stop assembly includes a first drive assembly and a first stop member 270; specifically, the first drive assembly is disposed on the support 260 and located at the bottom of the first conveying track 230, and the first stop member 270 is connected to the first drive assembly; wherein, the first side plate 234 of the first conveying track 230 is provided with a first clearance groove 235 for avoiding the first stop member 270, and the first drive assembly is used to drive the first stop member 270 to reciprocate between the temporary storage position 231 and the first clearance groove 235. The second stop assembly includes a second drive assembly and a second stop member 280. Specifically, the second drive assembly is disposed on the support 260 and located at the bottom of the first conveying track 230, and the second stop member 280 is connected to the second drive assembly. The first side plate 234 has a second clearance groove 236 for avoiding the second stop member 280, and the second drive assembly is used to drive the second stop member 280 to reciprocate between the first detection position 232 and the second clearance groove 236.

[0048] Understandably, this solution integrates the first and second stop components on the bottom support 260 of the conveyor track, and controls the avoidance actions of the first stop component 270 and the second stop component 280 through the first and second drive components respectively. This avoids the situation where the first stop component 270 and the second stop component 280 fail to avoid the test tube rack 400 in time and cause a hard collision and squeezing, reduces the deformation and wear of the first stop component 270 and the second stop component 280, extends their service life, and prevents the test tube rack 400 from shifting and sample spillage, thus ensuring the continuity and stability of the test tube conveying and testing process.

[0049] like Figure 6 and Figure 7 As shown, in a typical embodiment of the present invention, two first conveying tracks 230 are provided and arranged in parallel; wherein, the first conveying track 230 closer to the analysis device 100 is a conventional conveying track for conveying conventional samples, and the other first conveying track 230 is an emergency conveying track for conveying emergency samples. A second conveying track 240 is provided for conveying completed conventional or emergency samples to the rack 310. A transfer track 250 can reciprocate between the conventional conveying track and the second conveying track 240, or between the emergency conveying track and the second conveying track 240, to transfer the completed test tube rack 400 from the conventional or emergency conveying track to the second conveying track 240. The conventional transport track has a temporary storage position 231 and a first detection position 232 sequentially arranged from the sample inlet to the sample outlet. The track device 200 has a first stop component and a second stop component sequentially arranged from the sample inlet to the sample outlet. The first stop component is used to stop the test tube rack 400 at the temporary storage position 231, and the second stop component is used to stop the test tube rack 400 at the first detection position 232. The emergency transport track has a second detection position 233 adjacent to the first detection position 232. The track device 200 also has another second stop component arranged from the sample inlet to the sample outlet to stop the test tube rack 400 at the second detection position 233. A third clearance groove is opened on the side plate of the first transport track 230 away from the analysis device 100. The second stop component 280 corresponding to the stop of the test tube rack 400 at the second detection position 233 can move back and forth between the second detection position 233 and the third clearance groove.

[0050] like Figure 1 and Figure 2As shown, in some embodiments of the present invention, the analytical device 100 includes: a base 110, a reaction disk 120, a third drive assembly, a detection module 130, a sample dispensing module 140, a reagent dispensing module, a mixing module 170, a cleaning mechanism 180, and a liquid path module. Specifically, the reaction disk 120 is located in the middle of the base 110, and multiple reaction cups are arranged in a ring inside the reaction disk 120. The output end of the third drive assembly is connected to the reaction disk 120 to drive the reaction disk 120 to rotate. The detection module 130 is located outside the reaction cups and is used to detect the components of the solution inside the reaction cups. The sample dispensing module 140 is used to dispense a first sample or a second sample into the reaction cups and to achieve self-cleaning. The reagent dispensing module includes a first reagent dispensing unit 150 and a second reagent dispensing unit 160 for dispensing and cleaning reagents. The mixing module... Unit 170 includes a first stirring unit 171 and a second stirring unit 172, used to stir and mix the sample solution and reagent solution in the reaction vessel. The cleaning mechanism 180 is used to clean the reaction vessel by filling and draining liquids. The liquid path module is connected to the sample filling module 140, the reagent filling module, the stirring and mixing module 170 and the cleaning mechanism 180 respectively, and is used for liquid path transportation during the reaction. The sample filling module 140, the reagent filling module, the stirring and mixing module 170 and the cleaning mechanism 180 are arranged sequentially along the rotation direction of the reaction plate 120, and the liquid path module is located at the bottom of the base 110.

[0051] Understandably, this solution improves the space utilization of the fully automated biochemical analyzer by rationally arranging the sample dispensing module 140, reagent dispensing module, mixing module 170, and cleaning mechanism 180 along the rotation direction of the reaction plate 120, and integrating the liquid path module at the bottom of the base 110. This achieves a streamlined and integrated operation of sample dispensing, reagent dispensing, mixing, reaction detection, and reaction cup cleaning. At the same time, by setting up self-cleaning and independent cleaning mechanisms 180, the sample detection efficiency and accuracy are improved, ensuring a stable and reliable detection process.

[0052] like Figure 1 and Figure 2 As shown, in another typical embodiment of the present invention, the analysis device 100 is further provided with an emergency test tube tray 190, in which technicians can manually place emergency sample tubes into the emergency test tube tray 190, and the sample dispensing module 140 can draw samples from the emergency test tube tray 190 and dispense them into the corresponding reaction cup.

[0053] like Figure 10 As shown, to solve the above-mentioned technical problems, the present invention also provides a detection method for a fully automated biochemical analyzer. The detection method is applied to a fully automated biochemical analyzer as in any of the above examples, and the detection method includes the following steps: S1. System power-on initialization, control each mechanism to reset to the initial state; S2. The control conveying device 300 pushes multiple sets of test tube racks 400 on the frame 310 sequentially to the temporary storage position 231 or the first detection position 232 of the first conveying track 230; S3, the control and analysis device 100 sequentially executes the reaction cup cleaning, sample addition, reagent addition, stirring and mixing and component detection process; S4. After the test is completed, control the transfer track 250 to transfer the test tube rack 400 to the second transfer track 240 and return it to the rack 310; S5. Repeat steps S2 to S4 until all samples are tested, then the control system is reset and enters standby mode. When each mechanism is reset to its initial state: the pushing mechanism 320 is located in the first conveying position, the pushing member 330 and the stop member 311 are separated from each other and the stop member 311 restricts the test tube rack 400 from sliding off the frame 310, the pushing rod 322 and the pushing member 330 abut against each other, the elastic member 340 is in a stretched state, the first stop member 270 is located in the first clearance groove 235, the second stop member 280 is located in the second clearance groove 236, each module of the analysis device 100 is on standby and the liquid circuit module is ready.

[0054] In some embodiments of the present invention, the control process for the conveying device 300 to push the test tube rack 400 and reset in step S2 includes: S21, control the pushing mechanism 320 to move from the first conveying position to the second conveying position, so that the end of the pusher 330 near the frame 310 abuts against the stop 311, drive the stop 311 to avoid the test tube rack 400, and push the push rod 322 to push the test tube rack 400 from the frame 310 to the sample inlet end 210 of the track device 200, while the elastic member 340 returns from the stretched state to the initial state. S22. After the test tube rack 400 is sent into the first conveying track 230, the control push mechanism 320 returns from the second conveying position to the first conveying position, so that the pusher 330 and the stop 311 separate from each other, the stop 311 resets and restricts the test tube rack 400 from sliding off the frame 310.

[0055] In some embodiments of the present invention, step S2 further includes positioning control of the track device 200, specifically including the following steps: after the test tube rack 400 enters the first conveying track 230, the first stop component is controlled to move to the temporary storage position 231 to stop the test tube rack 400 at the temporary storage position 231; when testing is required, the first stop component is controlled to move into the first clearance groove 235, the first conveying track 230 conveys the test tube rack 400 to the first detection position 232, and the second stop component is controlled to move to the first detection position 232 to stop the test tube rack 400 at the first detection position 232; Step S4 also includes the recovery control of the track device 200, specifically including the following steps: after the sample detection at the first detection position 232 is completed, the transfer track 250 is controlled to move to the sample outlet end 220 of the first conveying track 230, and at the same time the second stop component is controlled to avoid it, so that the test tube rack 400 that has completed the detection is transported to the transfer track 250, and then the test tube rack 400 is transferred to the second conveying track 240 and recovered to the rack 310 via the transfer track 250.

[0056] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
