[0028] The embodiments and features of the embodiments in the present application can be combined with each other as long as they are not contradictory. The present invention will be described in detail below in conjunction with the embodiments with reference to the drawings.

[0029] The terms used herein are not intended to limit the exemplary embodiments according to the present application, but are used only to describe particular embodiments.

[0030] The relative arrangement of components and steps, numerical expressions, and values described in these embodiments do not limit the scope of the present application unless otherwise specified. It should be understood that, for ease of explanation, the dimensions of the various parts shown in the drawings are not drawn to scale. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but, where appropriate, the techniques, methods, and apparatus should be considered part of the patented specification. In all examples shown and discussed herein, any specific values should be construed as merely illustrative, not limiting. Thus, other examples of the illustrative embodiments may have different values. Similar symbols and letters represent similar items in the following drawings, so that once an item is defined in one drawing, there is no need to further discuss it in subsequent drawings.

[0031] As shown in Figures 1 and 2, the sample analyzer 100 provided by the present invention includes a first rail 21, a second rail 22, a reaction disk 10, an electrolyte detection mechanism 30, a first sample addition mechanism, and a second sample addition mechanism.

[0032] The reaction disk 10 is provided on a stage, and reaction vessels containing specimens that require biochemical testing are placed on the reaction disk 10.

[0033] The electrolyte detection mechanism 30 is provided on the above-mentioned stage and is located outside the reaction disk 10. A detection container for containing a specimen that requires electrolyte detection is placed on the electrolyte detection mechanism 30.

[0034] The first specimen adding mechanism is installed on the aforementioned stage and positioned outside the reaction disk 10, and transfers the specimen positioned on the first rail 21 into the aforementioned reaction vessel, and performs a biochemical test on the specimen.

[0035] The second specimen adding mechanism is installed on the aforementioned stage and positioned outside the reaction disk 10, and transfers the specimen positioned on the second rail 22 into the aforementioned detection container, and performs electrolyte detection on the specimen.

[0036] In this embodiment, the second specimen addition mechanism described above transfers the specimen on the second rail 22 independently to the detection vessel placed on the electrolyte detection mechanism 30, and the first specimen addition mechanism described above transfers the specimen on the first rail 21 independently to the reaction vessel placed on the reaction disk 10. In this way, by independently transferring the specimen to the detection vessel and the reaction vessel, it is possible to efficiently transfer the specimen required for electrolyte detection without affecting the dispensing of the specimen into the reaction vessel placed on the reaction disk 10.

[0037] Furthermore, the reaction disk 10 is configured to form a discharge position. The first specimen addition mechanism aspirates a specimen from the first rail 21, and transfers and discharges the specimen into a reaction vessel located at the discharge position.

[0038] Furthermore, a plurality of reaction vessels can be placed on the reaction disk 10. The reaction disk 10 can rotate to move the plurality of reaction vessels along a third rotation path. The plurality of reaction vessels sequentially pass through the discharge position while rotating along the third rotation path.

[0039] Furthermore, the reaction disk 10 has a horizontal line of symmetry 102 and a vertical line of symmetry 104 that pass through the third center of rotation 15. The horizontal line of symmetry 102 and the vertical line of symmetry 104 divide the reaction disk 10 into a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant.

[0040] The electrolyte detection mechanism 30, the first rotation center 421 of the second sample addition mechanism, and the second rail 22 are provided between the first rail 21 and the horizontal symmetry line 102, and are located on the same side of the vertical symmetry line 104. This allows the electrolyte module including the electrolyte detection mechanism 30, the second sample addition mechanism, and the second rail 22 to be integrated within the limited space of the stage. Therefore, the sample analyzer 100 can efficiently perform biochemical analysis and simultaneously efficiently detect electrolytes within a limited space.

[0041] In one embodiment, the aforementioned electrolyte module is disposed outside the reaction disk 10 and is located in the first quadrant.

[0042] In another embodiment, the aforementioned electrolyte module is disposed outside the reaction disk 10 and is located in the second quadrant.

[0043] In other embodiments, the electrolyte module may be provided outside the reaction disk 10 and located in the third quadrant, or may be provided outside the reaction disk 10 and located in the fourth quadrant.

[0044] Furthermore, only the specimens transferred to the reaction vessels are contained in the specimen vessels held in the first specimen rack. That is, after the first specimen loading mechanism has completed the collection of the samples from the specimen vessels held in the first specimen rack, the first specimen rack is directly collected.

[0045] At least the specimens transferred into the detection containers are contained in specimen containers held in a second specimen rack. That is, when the second specimen adding mechanism finishes collecting samples from the specimen containers held in the second specimen rack, the second specimen rack is collected.

[0046] In one embodiment, an electrolyte sampling point is formed at the intersection of the sampling needle of the second sample addition mechanism and the second rail 22. The sampling needle of the second sample addition mechanism samples from a sample container located at the electrolyte sampling point.

[0047] When the second sample addition mechanism transfers the sample in the second rail 22 to the aforementioned detection container, i.e., when the second sample addition mechanism transfers the sample in the sample container held in the second sample rack to the aforementioned detection container, the second rail 22 moves each sample container held in the second sample rack in sequence so as to pass through the aforementioned electrolyte sampling point, facilitating sampling by the sampling needle of the second sample addition mechanism.

[0048] Specifically, the sampling needle of the second specimen adding mechanism rotates around the first rotation center 421 between the electrolyte sampling point and the detection container to transfer and inject the specimen.

[0049] In another embodiment, due to limited space available for installation of the second rail 22, the second sample rack on the second rail 22 cannot move on the second rail 22 to pass each sample container carried thereby sequentially through the aforementioned electrolyte sampling points.

[0050] Therefore, after the second sample rack is transferred to the second rail 22, the second sample rack is placed on the second rail 22, and the second sample addition mechanism can move into a different sample container carried by the second sample rack to collect a sample.

[0051] Specifically, the sampling needle of the second sample addition mechanism can move into a different sample container carried by the second sample rack placed on the second rail 22 to perform sampling.

[0052] In one embodiment, the second sample application mechanism includes a collapsible arm and a sampling needle, and the collapsible arm can move the sampling needle into a different sample container carried by the second sample rack to collect a sample with the sampling needle.

[0053] Specifically, the folding arm includes a first sub-folding arm 422 and a second sub-folding arm 423. One end of the first sub-folding arm 422 is rotatable around a first rotation center 421, and the other end is connected to one end of the second sub-folding arm 423. The second sub-folding arm 423 is rotatable relative to the first sub-folding arm 422. The other end of the second sub-folding arm 423 is connected to the sampling needle.

[0054] By placing the sampling needle on the folding arm, the sampling needle can sample within a second sampling zone on the second rail 22. Since the second sampling zone can accommodate at least one second sample rack, the sampling needle can sample from any sample container in the second sample rack placed in the second sampling zone.

[0055] In another embodiment, the second sample application mechanism includes a telescopic arm and a sampling needle, and the telescopic arm can move the sampling needle into a different sample container carried by the second sample rack to collect a sample with the sampling needle.

[0056] Specifically, the telescopic arm includes at least a first sub-telescopic arm and a second sub-telescopic arm. One end of the first sub-foldable arm is rotatable around a first rotation center 421, and the other end is connected to one end of the second sub-telescopic arm. The second sub-telescopic arm is extendable and retractable relative to the first sub-telescopic arm. The other end of the second sub-telescopic arm is connected to the sampling needle.

[0057] By installing the sampling needle on the telescopic arm, the sampling needle can perform sampling within the second sampling zone on the second rail 22. Since the second sampling zone can accommodate at least one second sample rack, the sampling needle can sample from any sample container in the second sample rack placed in the second sampling zone.

[0058] Additionally, the electrolyte detection mechanism 30 includes at least one sample injection location for injecting a sample for electrolyte detection.

[0059] In one particular embodiment, the electrolyte detection mechanism 30 includes a first sample injection position 31 and a second sample injection position 32. The second sample addition mechanism can transfer the sample to the detection reservoir at the first sample injection position 31 or the second sample injection position 32.

[0060] Furthermore, the first sample addition mechanism includes a first sample addition arm 411 and a second sample addition arm 412, which are independent of each other. The first sample addition arm 411 and the second sample addition arm 412 each transfer the sample in the sample container carried by the first sample rack on the first rail 21 into a reaction container placed on the reaction disk 10.

[0061] In one embodiment, the sampling needles in the first sample addition arm 411 and the second sample addition arm 412 each move along a straight line to transfer the sample.

[0062] In another embodiment, the first sample addition arm 411 rotates about a second pivot point 413 and the second sample addition arm 412 rotates about a third pivot point 414 .

[0063] Furthermore, in one embodiment, the reaction disk 10 has a single ring structure, and a plurality of third mounting positions are formed along the third rotation path. Each of the third mounting positions can mount one reaction vessel. The reaction disk 10 is rotatable, and moves the plurality of third mounting positions to sequentially pass through the dispensing positions.

[0064] In another embodiment, the reaction disc 10 has a double ring structure, that is, includes a reaction outer tray 11 and a reaction inner tray 12 provided inside the reaction outer tray 11 .

[0065] The sampling needle of the first sample addition arm 411 is used to transfer the sample located on the first rail 21 into a reaction vessel placed on the inner reaction tray 12. The sampling needle of the second sample addition arm 412 is used to transfer the sample located on the first rail 21 into a reaction vessel placed on the outer reaction tray 11.

[0066] Specifically, the reaction inner tray 12 is configured to form an inner sample dispensing position 121 , and the reaction outer tray 11 is configured to form an outer sample dispensing position 111 .

[0067] A plurality of third internal mounting positions 122 are formed along the third internal rotation path in the reaction inner tray 12. Each of the third internal mounting positions 122 can mount one of the reaction vessels.

[0068] The reaction inner tray 12 can be rotated so that the plurality of third inner placement positions 122 interlock with each other and pass through the inner sample discharge position 121 in sequence.

[0069] A plurality of third outer placement positions 112 are formed along the third outer rotation path on the outer reaction tray 11. Each of the third outer placement positions 112 can place one reaction vessel thereon.

[0070] The outer reaction tray 11 can rotate so that the plurality of third outer placement positions 112 interlock with each other and pass through the outer sample discharge position 111 in sequence.

[0071] Furthermore, both the first sample addition arm 411 and the second sample addition arm 412 perform sampling at a common sampling point 211 on the first rail 21. The first sample rack moves on the first rail 21 so that each sample container in the first sample rack reaches the common sampling point 211 in sequence.

[0072] Specifically, the movement trajectory of the sampling needle of the first sample addition arm 411 and the movement trajectory of the sampling needle of the second sample addition arm 412 intersect with the first rail 21 and the common sampling point 211, respectively, so that the sampling needle of the first sample addition arm 411 and the sampling needle of the second sample addition arm 412 both sample at the common sampling point 211.

[0073] By providing the common sampling point 211, each sample container carried on the first sample rack is sampled by the sampling needle of the first sampling arm 411 or the sampling needle of the second sampling arm 412 as it passes through the common sampling point 211 in sequence. This effectively shortens the movement path of the first sample rack on the first rail 21, reduces the difficulty of controlling the movement of the first sample rack on the first rail 21, and improves the transport efficiency and sampling efficiency of the sample containers.

[0074] In addition, by providing the common sampling point 211, the movement paths of the sampling needles of the first sampling arm 411 and the second sampling arm 412 can be calibrated using the common sampling point 211 as a reference point, with high calibration efficiency. Furthermore, by bringing the first sampling arm 411 and the second sampling arm 412 closer to each other, the space occupied by the first sampling arm 411 and the second sampling arm 412 can be reduced, and the degree of integration of the first sampling arm 411 and the second sampling arm 412 can be increased.

[0075] In the single-ring structure reaction disk 10, the sampling needle of the first sample addition arm 411 and the sampling needle of the second sample addition arm 412 each transfer the sample collected from the common sampling point 211 into a reaction vessel placed on the reaction disk 10.

[0076] In the reaction disk 10 with a double ring structure, the sampling needle of the first sample addition arm 411 can transfer the sample collected from the common sampling point 211 into a reaction vessel placed on the reaction inner tray 12 or the reaction outer tray 11. The sampling needle of the second sample addition arm 412 can also transfer the sample collected from the common sampling point 211 into a reaction vessel placed on the reaction inner tray 12 or the reaction outer tray 11.

[0077] Preferably, the sampling needle of the first sample addition arm 411 is used to transfer the sample collected from the common sampling point 211 into a reaction vessel placed on the inner reaction tray 12, and the sampling needle of the second sample addition arm 412 is used to transfer the sample collected from the common sampling point 211 into a reaction vessel placed on the outer reaction tray 11.

[0078] Furthermore, the first rotation center 421 and the second rotation center 413 are provided on both sides of the vertical symmetry line 104. The third rotation center 414 and the second rotation center 413 are located on the same side of the vertical symmetry line 104. This allows the first sample addition mechanism and the second sample addition mechanism to be disposed on both sides of the vertical symmetry line 104, preventing interference between the first sample addition mechanism and the second sample addition mechanism when injecting the biochemical test sample and the electrolyte detection sample, respectively.

[0079] Furthermore, the second rotation center 413 is located between the first rotation center 421 and the third rotation center 414. Here, in one specific embodiment, the sampling needle of the first sample addition arm 411 is used to inject the sample in the sample container at the common sampling point 211 into a reaction container placed on the inner reaction tray 12, and the sampling needle of the second sample addition arm 412 is used to inject the sample in the sample container at the common sampling point 211 into a reaction container placed on the outer reaction tray 11.

[0080] In one embodiment, samples located on first rail 21 and samples located on second rail 22 enter sample analyzer 100 via first rail 21 as described above.

[0081] Furthermore, the sample analyzer 100 further includes a sample rack transfer mechanism 23. The second sample rack is transferred from the first rail 21 to the second rail 22 via the sample rack transfer mechanism 23 to facilitate sampling on the second rail 22 by the second sample addition mechanism. This prevents the second sample addition mechanism from sampling on the first rail 21 and also enables independent sampling by the first and second sample addition mechanisms, allowing the sample analyzer 100 to efficiently perform biochemical sampling while simultaneously performing electrolyte detection sampling without slowing down the speed.

[0082] Furthermore, the sample analyzer 100 further includes a third rail 24 used for collecting the sample racks. After the first sample rack and the second sample rack have completed their corresponding sampling, the sample rack transfer mechanism 23 transfers the first sample rack and the second sample rack to the third rail 24. The first sample rack and the second sample rack leave the sample analyzer 100 via the third rail 24.

[0083] In one embodiment, the first rail 21, the second rail 22, and the third rail 24 are parallel to one another. The sample rack transfer mechanism 23 can also be used to transfer a first sample rack on the first rail 21 or a second sample rack on the second rail 22 to the third rail 24.

[0084] Specifically, the sample rack transfer mechanism 23 can transfer the sample rack between the first rail 21 and the second rail 22, between the first rail 21 and the third rail 24, and between the second rail 22 and the third rail 24.

[0085] Furthermore, in one embodiment, the sample rack transfer mechanism 23 includes a relay rail 231 and a first drive device 232. The first drive device 232 can drive the relay rail 231 to connect with the first discharge end 213 of the first rail 21 in order to facilitate transferring the first sample rack or the second sample rack on the first rail 21 to the relay rail 231.

[0086] The first drive device 232 is also used to drive the relay rail 231 to connect with the input / output end 221 of the second rail 22 to facilitate transferring the second sample rack on the relay rail 231 to the second rail 22 or transferring the second sample rack on the second rail 22 to the relay rail 231.

[0087] The first drive device 232 can further drive the relay rail 231 so that the relay rail 231 connects with the third supply end 241 of the third rail 24, thereby transferring the first sample rack or the second sample rack on the relay rail 231 to the third rail 24, and facilitating the first sample rack or the second sample rack to be separated from the sample analyzer 100 by the third rail 24.

[0088] In another embodiment, the sample rack transfer mechanism 23 includes a second drive device and a gripper. Driven by the second drive device, the gripper transfers the second sample rack on the first rail 21 to the second rail 22, facilitating the second sample adding mechanism to collect a sample required for electrolyte detection from the second sample rack.

[0089] Under the drive of the second drive unit, the gripper transfers the first sample rack on the first rail 21 to the third rail 24, and transfers the second sample rack on the second rail 22 to the third rail 24, facilitating the first sample rack or the second sample rack to be removed from the sample analyzer 100 by the third rail 24.

[0090] In some more specific embodiments, the second drive device may be a drive mechanism, such as a three-dimensional movement module or a robot arm, for driving the aforementioned gripper to transport the sample rack between the first rail 21, the second rail 22, and the third rail 24.

[0091] Furthermore, in one embodiment, the first rail 21 can be used to transport a first sample rack and a second sample rack, in which sample containers held in the first sample rack contain samples that require biochemical testing.

[0092] After the first sample adding mechanism has completed collection of the samples required for the biochemical test in the sample containers carried by the first sample rack, the first sample rack moves along the first rail 21 toward the sample rack transfer mechanism 23 and is transferred to the relay rail 231. The first driving device 232 then drives the relay rail 231 to connect it with the third supply end 241 of the third rail 24, thereby transferring the first sample rack to the third rail 24. Finally, the first sample rack moves along the third rail 24 and leaves the sample analyzer 100.

[0093] Alternatively, after the first sample addition mechanism collects a sample required for a biochemical test in a sample container carried on the first sample rack, the second drive device drives the gripper to clamp the first sample frame and transfers it to the third rail 24.

[0094] Furthermore, the second sample rack described above is transported from the first rail 21 to the second rail 22, and holds samples that require electrolyte detection.

[0095] In one embodiment, the sample containers carried in the second sample rack contain samples requiring electrolyte detection.

[0096] Specifically, after the second sample rack enters the sample analyzer 100 from the first rail 21, the second sample rack moves along the first rail 21 to the first discharge end 213 of the first rail 21, and then moves from the first discharge end 213 to the relay rail 231.

[0097] Thereafter, the first drive device 232 drives the relay rail 231 carrying the second sample rack so that it connects with the input / output end 221 of the second rail 22, and after connection, transfers the second sample rack to the second rail 22, facilitating the second sample addition mechanism to collect the sample required for electrolyte detection.

[0098] When the second sample addition mechanism completes collection of the sample requiring electrolyte detection from the second sample rack, the second sample rack moves to the input / output end 221 of the second rail 22 and is transferred to the relay rail 231.

[0099] Next, the first drive device 232 drives the relay rail 231 so that the relay rail 231 connects to the third supply end 241 of the third rail 24, and transfers the second sample rack to the third rail 24. Finally, the second sample rack leaves the sample analyzer 100 via the third rail 24.

[0100] Alternatively, after the second sample rack enters the sample analyzer 100 from the first rail 21, the second drive unit drives the gripper to grip the second sample rack with the gripper and move it to the second rail 22. Then, the second sample addition mechanism collects a sample required for electrolyte detection from a sample container held in the second sample rack.

[0101] When the second sample adding mechanism completes collection of the sample requiring electrolyte detection from the second sample rack, the second drive unit again drives the gripper to grip the second sample rack and transfer it to the third rail 24. The second sample rack then moves away from the sample analyzer 100 via the third rail 24.

[0102] In another embodiment, the sample containers held in the second sample rack contain samples requiring electrolyte detection and samples requiring biochemical testing. The samples held in the sample containers held in the second sample rack are sampled by the sampling needle of the first sampling arm 411 as they pass through the common sampling point 211 on the first rail 21, or by the sampling needle of the second sampling arm 412, and then move to the second rail 22 and are sampled by the sampling needle of the second sample adding mechanism. This allows the sample containers held in the second sample rack to be efficiently sampled by both the first sample adding mechanism and the second sample adding mechanism along their movement path, improving both sample transport efficiency and sample collection efficiency.

[0103] Specifically, after the first sample addition mechanism completes collection of the sample required for the biochemical test in the sample container carried by the second sample rack, the second sample rack moves along the first rail 21 toward the sample rack transfer mechanism 23 and is transferred onto the relay rail 231.

[0104] Next, the first drive device 232 drives the relay rail 231 to connect to the input / output end 221 of the second rail 22, and after connection, transfers the second sample rack to the second rail 22, facilitating collection of the sample required for electrolyte detection by the second sample addition mechanism.

[0105] When the second sample addition mechanism completes collection of the sample required for electrolyte detection in the second sample rack, the second sample rack moves to the input / output end 221 of the second rail 22 and is transferred onto the relay rail 231.

[0106] Thereafter, the first drive device 232 drives the relay rail 231 to connect with the third supply end 241 of the third rail 24, and transfers the second sample rack to the third rail 24. Finally, the second sample rack leaves the sample analyzer 100 via the third rail 24.

[0107] Alternatively, after the second sample rack enters the sample analyzer 100 from the first rail 21, the first sample addition mechanism collects samples required for biochemical testing from the sample containers carried in the second sample rack located on the first rail 21. After the first sample addition mechanism completes sampling, the second drive device drives the gripper to grip the second sample rack and transfers the second sample rack onto the second rail 22.

[0108] After the second sample rack is transferred onto the second rail 22, the second sample adding mechanism collects a sample required for electrolyte detection in the sample container carried by the second sample rack.

[0109] After the second sample addition mechanism completes sampling, the second drive device again drives the gripper so that the gripper clamps the second sample rack and moves it onto the third rail 24, and the second sample rack moves away from the sample analyzer 100 via the third rail 24.

[0110] Furthermore, the sample analyzer 100 further includes a fourth rail 25 that can be used to transport at least a third sample rack. The sample containers carried in the third sample rack contain emergency samples.

[0111] Specifically, the fourth rail 25 is parallel to the first rail 21, the second rail 22, and the third rail 24. Moreover, the relay rail 231 can be connected to the fourth rail 25. Alternatively, the second drive device can drive the gripper so as to grip the third sample rack on the fourth rail 25.

[0112] The first specimen adding mechanism can also collect emergency samples necessary for biochemical analysis from the third specimen rack on the fourth rail 25.

[0113] Specifically, the first sample addition arm 411 rotates around the second rotation center 413 so that the sampling needle of the first sample addition arm 411 intersects with the fourth rail 25 to form the first emergency sampling point 251. The second sample addition arm 412 rotates around the third rotation center 414 so that the sampling needle of the second sample addition arm 412 intersects with the fourth rail 25 to form the second emergency sampling point 252.

[0114] The third sample rack moves on the fourth rail 25 so that the plurality of sample containers carried on the third sample rack pass the second emergency sampling point 252 and the first emergency sampling point 251 in sequence.

[0115] In the reaction disk 10 with a single ring structure, the first specimen adding mechanism described above samples a specimen from a specimen container located at the first emergency sampling point 251, and transfers and injects the specimen into a reaction container located at the discharge position.

[0116] In the reaction disk 10 with a double ring structure, the sampling needle of the first sample addition arm 411 samples from a sample container located at the first emergency sampling point 251 and transfers it to a reaction container located at the inner sample discharge position 121. The sampling needle of the second sample addition arm 412 samples from a sample container located at the second emergency sampling point 252 and transfers it to a reaction container located at the outer sample discharge position 111.

[0117] Furthermore, a first cleaning position 415 is provided below the movement trajectory of the sampling needle of the first sample addition arm 411. The first cleaning position 415 is located between the common sampling point 211 and the inner sample dispensing position 121 along the movement trajectory of the sampling needle, and is far away from the second pivot center 413. A second cleaning position 416 is provided below the movement trajectory of the sampling needle of the second sample addition arm 412. The second cleaning position 416 is located between the common sampling point 211 and the outer sample dispensing position 111 along the movement trajectory of the sampling needle, and is far away from the second pivot center 413.

[0118] In one embodiment, a second sample rack, which is transported only for performing biochemical tests, can also enter the sample analyzer 100 via the fourth rail 25 and be transferred from the fourth rail 25 to the second rail 22 via the sample rack transfer mechanism 23.

[0119] Specifically, when samples in sample containers held in the first sample rack or second sample rack on the first rail 21 are being sampled by the first sample addition mechanism, and when no emergency samples for biochemical analysis are being transported to the fourth rail 25, the second sample rack containing only samples for electrolyte detection enters the sample analyzer 100 along the fourth rail 25 and is transferred to the second rail 22 via the sample rack transfer mechanism 23, facilitating sampling by the second sample addition mechanism.

[0120] The sample analyzer 100 further includes a reagent container storage mechanism and a reagent injection mechanism. The reagent container storage mechanism includes a first reagent container storage mechanism and a second reagent container storage mechanism. The reagent injection mechanism includes a first reagent injection mechanism 62 and a second reagent injection mechanism 63.

[0121] The first reagent container storage mechanism is provided outside the reaction disk 10 and can accommodate a plurality of reagent containers. The first reagent container storage mechanism is rotatable so as to move the plurality of reagent containers along a first rotation path.

[0122] The first reagent container storage mechanism has a plurality of first placement positions formed along the first rotation path, and each of the first placement positions can accommodate one reagent container.

[0123] The first reagent container storage mechanism includes a first reagent aspirating position 51 and a second reagent aspirating position 52. The first reagent container storage mechanism rotates around a first rotation center 535, thereby moving the plurality of first placement positions to pass through the first reagent aspirating position 51 and the second reagent aspirating position 52 in sequence.

[0124] A plurality of reaction vessels can be placed on the reaction disk 10. The reaction disk 10 is rotatable so as to move the plurality of reaction vessels along the third rotation path.

[0125] Specifically, when the reaction disk 10 has a single ring structure, a plurality of third mounting positions are formed along the third rotation path on the reaction disk 10. Each of the third mounting positions can accommodate one reaction vessel.

[0126] The reaction disk 10 includes a first reagent dispensing position 13 and a second reagent dispensing position 14. The reaction disk 10 can be rotated around a third rotation center 15 to move the plurality of third placement positions so that they sequentially pass through the first reagent dispensing position 13 and the second reagent dispensing position 14.

[0127] The first reagent injection mechanism 62 includes a first reagent needle 61 and a second reagent needle that operate independently. The first reagent needle 61 is used to aspirate a reagent in a reagent container located at either the first reagent aspirating position 51 or the second reagent aspirating position 52, and transfer and dispense the reagent along a first straight line 551 into a reaction container located at either the first reagent dispensing position 13 or the second reagent dispensing position 14. The second reagent needle is used to aspirate a reagent in a reagent container located at the other of the first reagent aspirating position 51 or the second reagent aspirating position 52, and transfer and dispense the reagent along a second straight line 552 into a reaction container located at the other of the first reagent dispensing position 13 or the second reagent dispensing position 14.

[0128] After the reaction disk 10 rotates and moves the two target reaction vessels to the first reagent dispensing position 13 and the second reagent dispensing position 14, respectively, and after the aforementioned first reagent vessel storage mechanism rotates and moves the two target reagent vessels to the first reagent suction position 51 and the second reagent suction position 52, respectively, the first reagent needle 61 aspirates reagent from the target reagent vessel located at either the first reagent suction position 51 or the second reagent suction position 52, and transfers the aspirated reagent along the first straight line 551 to inject it into the target reaction vessel located at either the first reagent dispensing position 13 or the second reagent dispensing position 14.

[0129] The second reagent needle aspirates reagent from a target reagent container located at the other of the first reagent aspirating position 51 or the second reagent aspirating position 52, and transfers the aspirated reagent along the second straight line 552 to inject it into a target reaction container located at the other of the first reagent discharging position 13 or the second reagent discharging position 14.

[0130] Compared to the reagent injection method of the conventional sample analyzer 100, in this embodiment, the independently operating first reagent needle 61 transfers the reagent along the first straight line 551, and the independently operating second reagent needle transports the reagent along the second straight line 552. This significantly improves the efficiency of reagent injection into the reaction vessel, avoiding the first and second reagent needles 61 and 62 from aspirating and injecting the reagent back and forth, avoiding the need for rotating and resetting the aspirating reagent, effectively shortening the time the reaction disk 10 waits for the first and second reagent needles 61 and 62 to inject the reagent, shortening the time the first reagent vessel storage mechanism waits for the first and second reagent needles 61 and 62 to aspirate the reagent, and shortening the reagent transfer time and the reset time for the first and second reagent needles 61 and 62. Furthermore, the independently operating first and second reagent needles can also be controlled to transfer the reagent by controlling only the first reagent needle 61 or the second reagent needle as needed.

[0131] In one embodiment, the first reagent container storage mechanism is a single ring structure. The first plurality of placement positions transport reaction containers along the first rotation path around the first rotation center 535.

[0132] In another embodiment, the first reagent container storage mechanism has a double ring structure and includes a first reagent container storage inner plate 531 and a first reagent container storage outer plate 533. The first reagent container storage inner plate 531 is provided inside the first reagent container storage outer plate 533.

[0133] A plurality of first internal mounting positions 532 are formed along the first internal rotation path on the first reagent container storage internal platen 531. Each of the first internal mounting positions 532 can mount one reagent container.

[0134] A plurality of first outer mounting positions 534 are formed along the first outer rotation path on the first reagent container storage outer panel 533. Each of the first outer mounting positions 534 can mount one reagent container.

[0135] Furthermore, in one more specific embodiment, the first reagent suction position 51 is provided on a first internal rotation path of the first reagent container storage inner platen 531, and a plurality of first internal mounting positions 532 move along the aforementioned first internal rotation path to sequentially pass through the first reagent suction position 51, and the second reagent suction position 52 is provided on a first external rotation path of the first reagent container storage outer platen 533, and a plurality of first external mounting positions 534 move along the aforementioned first external rotation path to sequentially pass through the second reagent suction position 52.

[0136] In another more specific embodiment, the first reagent aspirating position 51 is provided on the first outer rotation path of the first reagent container storage outer platen 533, and the plurality of first outer mounting positions 534 move along the first outer rotation path and sequentially pass the first reagent aspirating position 51. The second reagent aspirating position 52 is provided on the first inner rotation path of the first reagent container storage inner platen 531. The plurality of first inner mounting positions 532 move along the first inner rotation path and sequentially pass the second reagent aspirating position 52.

[0137] In one embodiment, the first reagent container storage inner platen 531 and the first reagent container storage outer platen 533 maintain synchronous rotation.

[0138] In another embodiment, the first reagent container storage inner platen 531 is rotatable independently of the first reagent container storage outer platen 533. That is, when the first reagent container storage inner platen 531 rotates, the first reagent container storage outer platen 533 may remain stationary and unmoving, or may rotate at the same or a different number of rotations as the first reagent container storage inner platen 531. Alternatively, when the first reagent container storage outer platen 533 rotates, the first reagent container storage inner platen 531 may remain stationary and unmoving, or may rotate at the same or a different number of rotations as the first reagent container storage outer platen 533.

[0139] Furthermore, the independently rotatable first reagent container storage inner plate 531 can be controlled so that the aforementioned target reagent container moves directly to the first reagent suction position 51 or the second reagent suction position 52 corresponding to the first reagent needle 61, depending on the type of reagent to be aspirated from the reagent container placed at the first inner placement position 532.

[0140] The independently rotatable first reagent container storage outer plate 533 can be controlled so that the target reagent container moves directly to the second reagent suction position 52 or the first reagent suction position 51 corresponding to the second reagent needle, depending on the type of reagent to be aspirated in the reagent container placed at the first outer placement position 534.

[0141] While the first reagent container storage inner platen 531 and the first reagent container storage outer platen 533 maintain synchronous rotation, the independently rotatable first reagent container storage inner platen 531 and the first reagent container storage outer platen 533 facilitate the aspirating of reagent by the first reagent needle 61 and the second reagent needle. That is, when the first reagent needle 61 aspirates reagent in a target reagent container, the target reagent container corresponding to the second reagent needle cannot simultaneously reach the second reagent aspirating position 52. Therefore, after the first reagent needle 61 aspirates the reagent in the target reagent container, the reaction disk 10 rotates again to move the target reagent container corresponding to the second reagent needle to the second reagent aspirating position 52, thereby preventing the second reagent needle from aspirating. During this process, the target reagent container corresponding to the second reagent needle must stop twice as the reaction disk 10 rotates to reach the second reagent aspirating position 52.

[0142] Furthermore, in a more specific embodiment, the first reagent discharging position 13 is provided on the third internal rotation path of the reaction inner tray 12. The plurality of third internal placement positions 122 move along the third internal rotation path and pass through the first reagent discharging position 13 in sequence.

[0143] The second reagent discharging position 14 is provided on the aforementioned third outer rotation path of the reaction outer tray 11. The plurality of third outer placement positions 112 move along the aforementioned third outer rotation path and pass through the second reagent discharging position 14 in sequence.

[0144] In another more specific embodiment, the first reagent ejection position 13 is provided on the aforementioned third outer rotation path of the reaction outer tray 11, and multiple third outer placement positions 112 move along the aforementioned third outer rotation path and pass through the first reagent ejection position 13 sequentially.

[0145] The second reagent ejection position 14 is provided on the aforementioned third internal rotation path of the reaction inner tray 12, and the multiple third internal placement positions 122 move along the aforementioned third internal rotation path and pass through the second reagent ejection position 14 sequentially.

[0146] In one embodiment, the inner reaction tray 12 and the outer reaction tray 11 maintain synchronous rotation.

[0147] In another embodiment, the reaction inner tray 12 is rotatable independently of the reaction outer tray 11. That is, when the reaction inner tray 12 rotates, the reaction outer tray 11 may remain stationary and unmoving, or may rotate at the same or a different number of rotations as the reaction inner tray 12. Alternatively, when the reaction outer tray 11 rotates, the reaction inner tray 12 may remain stationary and unmoving, or may rotate at the same or a different number of rotations as the reaction outer tray 11.

[0148] Furthermore, the independently rotatable reaction inner tray 12 can be controlled so that the aforementioned target reaction vessel moves directly to the first reagent ejection position 13 or the second reagent ejection position 14 corresponding to the first reagent needle 61, depending on the type of reagent to be injected into the reaction vessel placed at the third inner placement position 122.

[0149] The independently rotatable outer reaction tray 11 can be controlled so that the target reaction vessel moves directly to the second reagent ejection position 14 or the first reagent ejection position 13 corresponding to the second reagent needle, depending on the type of reagent to be injected into the reaction vessel placed at the third outer placement position 112.

[0150] Compared to the reaction inner tray 12 and the reaction outer tray 11 rotating synchronously, the reaction inner tray 12 and the reaction outer tray 11 being able to rotate independently makes it easier to inject reagents using the first reagent needle 61 and the second reagent needle.

[0151] Furthermore, the sample analyzer 100 is provided with an independently rotatable inner reaction tray 12 and outer reaction tray 11, and an independently rotatable first reagent container storage inner plate 531 and first reagent container storage outer plate 533. The reagent placed on the first reagent container storage outer plate 533 is injected into a reaction container placed on the inner reaction tray 12 or outer reaction tray 11 through an independently operating first reagent needle 61, and the reagent placed on the first reagent container storage inner plate 531 is injected into a reaction container placed on the outer reaction tray 11 or inner reaction tray 12 through an independently operating second reagent needle. This allows the sample analyzer 100 to integrate two independent and parallel reagent supply, dispensing, and detection systems, effectively improving detection efficiency.

[0152] Furthermore, in one embodiment, a first center line is formed between the first center of rotation 535 and the third center of rotation 15. The first line 551 is parallel to the first center line, or directly intersects with the first center line, or intersects with an extension of the first center line. The second line 552 is parallel to the first center line, or directly intersects with the first center line, or intersects with an extension of the first center line.

[0153] Preferably, the first straight line 551 and the second straight line 552 are parallel to the first center line, and the distance from the first straight line 551 to the first center line is equal to the distance from the second straight line 552 to the first center line.

[0154] Furthermore, the time required for the first reagent needle 61 to move along the first straight line 551 from the first reagent suction position 51 to the first reagent discharge position 13 is the same as the time required for the second reagent needle to move along the second straight line 552 from the second reagent suction position 52 to the second reagent discharge position 14.

[0155] Furthermore, in one embodiment, the first reagent needle 61 and the second reagent needle are provided on the stand at a certain distance from each other.

[0156] Furthermore, the first reagent needle 61 is moved up and down in the vertical direction by an elevation drive device, which allows the first reagent needle 61 to move up and down between either the first reagent aspirating position 51 or the second reagent aspirating position 52, and between either the first reagent dispensing position 13 or the second reagent dispensing position 14.

[0157] Furthermore, the first reagent needle 61 is moved horizontally along the direction of the first straight line 551 by the horizontal drive device. This allows the first reagent needle 61 to move between the first reagent aspirating position 51 and the first reagent dispensing position 13 or the second reagent dispensing position 14, or between the second reagent aspirating position 52 and the second reagent dispensing position 14 or the first reagent dispensing position 13.

[0158] The second reagent needle is moved up and down in the vertical direction by a separate lifting drive device, which allows the second reagent needle to move up and down between one of the first reagent aspirating position 51 and the second reagent aspirating position 52, and between one of the first reagent dispensing position 13 and the second reagent dispensing position 14.

[0159] Furthermore, the second reagent needle is moved horizontally along the direction of a second straight line 552 by another horizontal drive device. This allows the second reagent needle to move between the first reagent aspirating position 51 and the first reagent dispensing position 13 or the second reagent dispensing position 14, or between the second reagent aspirating position 52 and the second reagent dispensing position 14 or the first reagent dispensing position 13.

[0160] In another embodiment, the first reagent needle 61 and the second reagent needle are provided on the same stand. The first reagent needle 61 and the second reagent needle described above are each moved up and down vertically by an elevation drive device, and moved horizontally along the corresponding first straight line 551 and second straight line 552 by a horizontal drive device.

[0161] Furthermore, the reaction disk 10 further includes a third reagent dispensing position 16 and a fourth reagent dispensing position 17. Moreover, the reaction disk 10 can rotate around a third rotation center 15 to sequentially pass through the third reagent dispensing position 16 and the fourth reagent dispensing position 17 through a plurality of third placement positions.

[0162] The second reagent injection mechanism 63 is used to inject a reagent from a reagent container placed in the second reagent container storage mechanism into a reaction container placed on the reaction disk 10.

[0163] The second reagent container storage mechanism is provided outside the reaction disk 10 and can accommodate a plurality of reagent containers. The second reagent container storage mechanism is rotatable so as to move the plurality of reagent containers along a second rotation path.

[0164] The second reagent container storage mechanism has a plurality of second placement positions formed along the second rotation path, each of which can accommodate one reagent container.

[0165] The second reagent container storage mechanism includes a third reagent aspirating position 57 and a fourth reagent aspirating position 58. The second reagent container storage mechanism rotates around a second rotation center 545, allowing the plurality of second placement positions to pass through the third reagent aspirating position 57 and the fourth reagent aspirating position 58 in sequence.

[0166] The second reagent injection mechanism 63 includes a third reagent needle and a fourth reagent needle that operate independently.

[0167] The aforementioned third reagent needle is used to aspirate reagent from a reagent container located at either the third reagent aspirating position 57 or the fourth reagent aspirating position 58, and then transfer and dispense the reagent along the third straight line 561 into a reaction container located at either the third reagent dispensing position 16 or the fourth reagent dispensing position 17.

[0168] The aforementioned fourth reagent needle is used to aspirate reagent from a reagent container located at the other of the third reagent suction position 57 or the fourth reagent suction position 58, and transfer and dispense the reagent along the fourth straight line 562 into a reaction container located at the other of the third reagent discharge position 16 or the fourth reagent discharge position 17.

[0169] After the reaction disk 10 rotates to move the two target reaction vessels to the third reagent dispensing position 16 and the fourth reagent dispensing position 17, respectively, and the aforementioned second reagent vessel storage mechanism rotates to move the two target reagent vessels to the third reagent suction position 57 and the fourth reagent suction position 58, respectively, the aforementioned third reagent needle aspirates reagent from the target reagent vessel located at either the third reagent suction position 57 or the fourth reagent suction position 58, and transfers the aspirated reagent along the third straight line 561 to inject it into the target reaction vessel located at either the third reagent dispensing position 16 or the fourth reagent dispensing position 17.

[0170] The aforementioned fourth reagent needle aspirates reagent from a target reagent container located at the other of the third reagent aspirating position 57 or the fourth reagent aspirating position 58, and transfers the aspirated reagent along the fourth straight line 562 to inject it into a target reaction container located at the other of the third reagent discharging position 16 or the fourth reagent discharging position 17.

[0171] In one embodiment, the second reagent container storage mechanism is a single ring structure, and the second plurality of mounting positions transport reaction containers along the second rotation path around the second rotation center 545.

[0172] In another embodiment, the second reagent container storage mechanism has a double ring structure and includes a second reagent container storage inner plate 541 and a second reagent container storage outer plate 543. The second reagent container storage inner plate 541 is provided inside the second reagent container storage outer plate 543.

[0173] A plurality of second internal mounting positions 542 are formed along the second internal rotation path on the second reagent container storage internal platen 541. Each of the second internal mounting positions 542 can mount one reagent container.

[0174] A plurality of second outer mounting positions 544 are formed along the second outer rotation path on the second reagent container storage outer panel 543. Each of the second outer mounting positions 544 can mount one reagent container.

[0175] Furthermore, in one more specific embodiment, the third reagent aspirating position 57 is provided on the second internal rotation path of the second reagent container storage inner platen 541, and the plurality of second internal mounting positions 542 move along the second internal rotation path to sequentially pass the third reagent aspirating position 57. The fourth reagent aspirating position 58 is provided on the second external rotation path of the second reagent container storage outer platen 543. The plurality of second external mounting positions 544 move along the second external rotation path to sequentially pass the fourth reagent aspirating position 58.

[0176] In another more specific embodiment, the third reagent suction position 57 is provided on the second external rotation path of the second reagent container storage outer platen 543, and the plurality of second external placement positions 544 move along the first external rotation path and pass through the third reagent suction position 57 sequentially.

[0178] In one embodiment, the second reagent container storage inner platen 541 and the second reagent container storage outer platen 543 maintain synchronous rotation.

[0179] In another embodiment, the second reagent container storage inner platen 541 is rotatable independently of the second reagent container storage outer platen 543. That is, when the second reagent container storage inner platen 541 rotates, the second reagent container storage outer platen 543 may remain stationary and unmoving, or may rotate by the same number of rotations as the second reagent container storage inner platen 541 or a different number of rotations. Alternatively, when the second reagent container storage outer platen 543 rotates, the second reagent container storage inner platen 541 may remain stationary and unmoving, or may rotate by the same number of rotations as the second reagent container storage outer platen 543 or a different number of rotations.

[0180] Furthermore, the independently rotatable second reagent container storage inner plate 541 can be controlled so that the aforementioned target reagent container moves directly to the third reagent suction position 57 or the fourth reagent suction position 58 corresponding to the third reagent needle, depending on the type of reagent to be aspirated from the reagent container placed at the second inner placement position 542.

[0181] The independently rotatable second reagent container storage outer plate 543 can be controlled so that the target reagent container described above moves directly to the third reagent suction position 57 or the fourth reagent suction position 58 corresponding to the fourth reagent needle, depending on the type of reagent to be aspirated from the reagent container placed at the second outer placement position 544.

[0182] Furthermore, in one embodiment, a second center line is formed between the second center of rotation 545 and the third center of rotation 15. A third line 561 is parallel to the second center line, or directly intersects with the second center line, or intersects with an extension of the second center line. A fourth line 562 is parallel to the second center line, or directly intersects with the second center line, or intersects with an extension of the second center line.

[0183] Preferably, the third straight line 561 and the fourth straight line 562 are each parallel to the second center connection line, and the distance from the third straight line 561 to the second center connection line is equal to the distance from the fourth straight line 562 to the second center connection line.

[0184] Furthermore, the reaction disk 10 has a horizontal line of symmetry 102 and a vertical line of symmetry 104 that pass through the third center of rotation 15. The horizontal line of symmetry 102 and the vertical line of symmetry 104 divide the reaction disk 10 into a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant.

[0185] In one embodiment, the first rotation center 535 and the second rotation center 545 are located on either side of the vertical symmetry line 104 and on the same side of the horizontal symmetry line 102. Thus, the first reagent container storage mechanism and the second reagent container storage mechanism are arranged to be distributed within the first and second quadrants and located outside the reaction disk 10, or to be distributed within the third and fourth quadrants and located outside the reaction disk 10.

[0186] In another embodiment, the first rotation center 535 and the second rotation center 545 are located on either side of the horizontal symmetry line 102 and on the same side of the vertical symmetry line 104. Thus, the first reagent container storage mechanism and the second reagent container storage mechanism are arranged to be distributed within the first and fourth quadrants and located outside the reaction disk 10, or to be distributed within the second and third quadrants and located outside the reaction disk 10.

[0187] Specifically, the reaction disk 10, the first reagent container storage mechanism, and the second reagent container storage mechanism are all provided on the stage. Moreover, to facilitate the attachment and detachment of reagent containers to and from the first reagent container storage mechanism and the second reagent container storage mechanism, the first reagent container storage mechanism and the second reagent container storage mechanism are located on the same side of the stage.

[0188] Furthermore, a center line 103 is formed between the first center of rotation 535 of the first reagent container storage mechanism and the second center of rotation 545 of the second reagent container storage mechanism.

[0189] The vertical symmetry line 104 and the vertical foot of the center line 103 are located at the midpoint of the center line 103 .

[0190] Specifically, the linear distance from the first rotation center 535 to the third rotation center 15 is equal to the linear distance from the second rotation center 545 to the third rotation center 15. As a result, the triangle formed by the lines connecting the three points of the first rotation center 535, the second rotation center 545, and the third rotation center 15 is an isosceles triangle. Moreover, the first reagent container storage mechanism and the second reagent container storage mechanism are symmetrically distributed on both sides of the reaction disk 10 along the vertical symmetry line 104.

[0191] 3, in another aspect, the present application further provides a sample transport method using the sample analyzer 100. The sample transport method includes the following steps.

[0192] In step S10, the sample rack enters the sample analyzer 100 from the first supply end 212 of the first rail 21.

[0193] In this step, the first rail 21 is provided on the outer side of the reaction disk 10. The reaction disk 10 is provided on a stage, and has reaction vessels placed thereon for accommodating specimens that require biochemical testing.

[0194] The sample rack holds sample containers, which are used for biochemical testing and / or electrolyte detection.

[0195] The first rail 21 is provided on the outside of the reaction disk 10 and is used to transport the aforementioned sample rack, and includes a first supply end 212 and a first discharge end 213. The first supply end 212 is the entrance end where the sample rack enters the first rail 21, and the first discharge end 213 is the end where the sample rack leaves the first rail 21.

[0196] In step S20, the sample rack is transferred from the first discharge end 213 of the first rail 21 to the sample rack transfer mechanism 23.

[0197] In this step, the sample rack transfer mechanism 23 includes a relay rail 231 and a first drive device 232. The first drive device 232 drives the relay rail 231 so that the relay rail 231 is connected to the first discharge end 213 of the first rail 21, in order to facilitate the transfer of the first sample rack or the second sample rack on the first rail 21 to the relay rail 231.

[0198] Specifically, the sample rack is transported via the first rail 21. Furthermore, after the relay rail 231 is connected to the first discharge end 213 of the first rail 21, the first rail 21 transports the sample rack so that the sample rack is transferred to the relay rail 231.

[0199] In step S30, the sample rack is transferred from the sample rack transfer mechanism 23 to the input / output end 221 of the second rail 22.

[0200] In this step, after the aforementioned sample rack is transferred to the relay rail 231, the first drive device 232 drives and moves the relay rail 231 on which the sample rack is placed, so that the relay rail 231 is connected to the input / output end 221 of the second rail 22, and then the aforementioned sample rack is transferred to the input / output end 221 of the second rail 22 via the relay rail 231.

[0201] In step S40, the sample rack described above is led from the input / output end 221 to the second sampling zone of the second rail 22.

[0202] In this step, after the sample rack reaches the inlet / outlet end 221 of the second rail 22, the sample rack is transported by the second rail 22 until it moves to the second sampling zone of the second rail 22.

[0203] In step S50, the second sample adding mechanism transfers the sample in the sample container held in the sample rack into the detection container held in the electrolyte detection mechanism 30.

[0204] After the sample rack moves to the second sampling zone, the second sample addition mechanism collects a sample required for electrolyte detection from a sample container carried in the sample rack located in the second sampling zone, and injects the collected sample into a detection container located at the first sample injection position 31 or the second sample injection position 32.

[0205] After the specimen for electrolyte detection is poured into the detection container, the electrolyte detection mechanism 30 performs electrolyte detection on the specimen.

[0206] In step S60, the second sample addition mechanism transfers the sample in the sample container carried in the sample rack into the detection container carried in the electrolyte detection mechanism 30, and then the sample rack moves from the second sampling zone to the input / output end 221 and is transferred from the input / output end 221 to the sample rack transfer mechanism 23.

[0207] In this step, when the second sample addition mechanism completes collection of a sample from a sample container carried on the aforementioned sample rack, the sample rack moves from the aforementioned second sampling zone toward the input / output end 221 until it reaches the input / output end 221.

[0208] Before or after the sample rack reaches the input / output end 221 , the first drive device 232 drives the relay rail 231 so that it connects with the input / output end 221 of the second rail 22 .

[0209] After the relay rail 231 is connected to the input / output end 221, the second rail 22 transports the sample rack and moves it to the relay rail 231. The sample rack is then moved away from the sample analyzer 100 by the relay rail 231 and the second drive device.

[0210] Furthermore, during the process in which the second sample addition mechanism transfers the sample in the sample container carried by the sample rack to the detection container, the sample rack is placed on the second rail 22, and the second sample addition mechanism moves into a different sample container carried by the sample rack to collect the sample.

[0211] Specifically, the sampling needle of the second sample addition mechanism can move into a different sample container carried by a sample rack placed on the second rail 22 to perform sampling.

[0212] In one embodiment, the second sample application mechanism includes a folding arm and a sampling needle, the folding arm being capable of moving the sampling needle into a different sample container carried in the sample rack to collect a sample.

[0213] Specifically, the folding arm includes at least a first sub-folding arm 422 and a second sub-folding arm 423. One end of the first sub-folding arm 422 is rotatable around a first rotation center 421, and the other end is connected to one end of the second sub-folding arm 423. The second sub-folding arm 423 is rotatable relative to the first sub-folding arm 422. The other end of the second sub-folding arm 423 is connected to the sampling needle.

[0214] By placing the sampling needle on the folding arm, the sampling needle can sample within a second sampling zone on the second rail 22. Since the second sampling zone can accommodate at least one second sample rack, the sampling needle can sample from any sample container in the second sample rack placed in the second sampling zone.

[0215] In another embodiment, the second sample application mechanism includes a telescopic arm and a sampling needle, and the telescopic arm can move the sampling needle into a different sample container carried by the second sample rack to collect a sample with the sampling needle.

[0216] Specifically, the telescopic arm includes at least a first sub-telescopic arm and a second sub-telescopic arm. One end of the first sub-foldable arm is rotatable around a first rotation center 421, and the other end is connected to one end of the second sub-telescopic arm. The second sub-telescopic arm is extendable and retractable relative to the first sub-telescopic arm. The other end of the second sub-telescopic arm is connected to the sampling needle.

[0217] By installing the sampling needle on the telescopic arm, the sampling needle can perform sampling within the second sampling zone on the second rail 22. Since the second sampling zone can accommodate at least one second sample rack, the sampling needle can sample from any sample container in the second sample rack placed in the second sampling zone.

[0218] As shown in FIG. 4, the aforementioned sample rack entering the sample analyzer 100 from the first supply end 212 of the first rail 21 further includes the following steps.

[0219] In step S11, the sample rack described above reaches the first sampling zone of the first rail 21 from the first supply end 212, and the sample containers carried by the sample rack pass through the common sampling point 211 in sequence.

[0220] In this step, the first sampling zone is located between the first supply end 212 and the first discharge end 213 of the first rail 21. The sample rack moves on the first rail 21 so that each sample container in the sample rack reaches the common sampling point 211 in sequence.

[0221] In step S12, while multiple sample containers are passing through the common sampling point 211 in sequence, the first sample addition mechanism transfers the sample in the sample container located at the common sampling point 211 to a reaction container placed on the reaction disk 10.

[0222] Specifically, the specimen injected into the reaction vessel placed on the reaction disk 10 is used for biochemical testing.

[0223] In step S13, the first sample addition mechanism transfers the sample in the sample container located at the common sampling point 211 into a reaction container placed on the reaction disk 10, and then the aforementioned sample rack moves from the first sampling zone to the first discharge end 213.

[0224] In this step, after the first sample addition mechanism completes sampling from the sample container carried in the sample rack located in the first sampling zone, the first rail 21 transports the sample rack and moves it from the first sampling zone to the first discharge end 213 to facilitate the transfer of the sample rack from the first discharge end 213 of the first rail 21 to the relay rail 231.

[0225] Furthermore, the first sample addition mechanism includes a first sample addition arm 411 and a second sample addition arm 412 that are independent of each other.

[0226] In this embodiment, the reaction disk 10 includes a reaction outer tray 11 and a reaction inner tray 12 provided inside the reaction outer tray 11 .

[0227] During the process in which the first sample addition mechanism transfers a sample from a sample container held in a first sample rack to a reaction container held on a reaction disk, the first sample addition arm 411 aspirates the first sample from one of the sample containers located at the common sampling point 211 and transfers the first sample into the reaction container placed on the inner reaction tray 12. During the process in which the first sample addition arm 411 transfers the first sample to the reaction container placed on the inner reaction tray 12, the second sample addition arm 412 aspirates the first sample from one of the sample containers located at the common sampling point 211 and transfers the first sample into the reaction container placed on the outer reaction tray 11. Alternatively, while the first sample is being transferred by the first sample addition arm 411 to the reaction vessel placed on the inner reaction tray 12, the second sample addition arm 412 aspirates a second sample from another sample vessel located at the common sampling point 211 and transfers the second sample into the reaction vessel placed on the outer reaction tray 11.

[0228] Specifically, the aforementioned first sample addition mechanism includes a first sample addition arm 411 and a second sample addition arm 412. In the reaction disk 10 with a double-ring structure, the sampling needle of the first sample addition arm 411 can transfer the sample collected from the common sampling point 211 into a reaction vessel placed on the inner reaction tray 12 or the outer reaction tray 11. The sampling needle of the second sample addition arm 412 can also transfer the sample collected from the common sampling point 211 into a reaction vessel placed on the inner reaction tray 12 or the outer reaction tray 11.

[0229] Preferably, the sampling needle of the first sample addition arm 411 is used to transfer the sample collected from the common sampling point 211 to a reaction vessel placed on the inner reaction tray 12, and the sampling needle of the second sample addition arm 412 is used to transfer the sample collected from the common sampling point 211 to a reaction vessel placed on the outer reaction tray 11.

[0230] In one specific embodiment, the sampling needle of the first sample addition arm 411 is used to inject the sample in the sample container at the common sampling point 211 into a reaction container placed on the inner reaction tray 12. The sampling needle of the second sample addition arm 412 is used to inject the sample in the sample container at the common sampling point 211 into a reaction container placed on the outer reaction tray 11.

[0231] As shown in Figure 3, after the aforementioned sample rack moves from the second sampling zone to the input / output end 221 and is transferred from the input / output end 221 to the sample rack transfer mechanism 23, the aforementioned sample transport method further includes the following steps.

[0232] In step S70, the first drive device 232 of the sample rack transfer mechanism 23 drives the relay rail 231 so that it is connected to the third supply end 241 of the third rail 24.

[0233] In this step, the sample analyzer 100 further includes a third rail 24 used to collect the sample rack. After the second sample addition mechanism completes sampling on the sample rack, the sample rack transfer mechanism 23 transfers the sample rack to the third rail 24, and the sample rack leaves the sample analyzer 100 via the third rail 24.

[0234] The first drive device 232 drives the relay rail 231 so that it is connected to the first discharge end 213 of the first rail 21, the input / output end 221 of the second rail 22, and the third supply end 241 of the third rail 24. After the second sample addition mechanism described above completes sampling from the sample rack, the second rail 22 moves to transport the sample rack to the relay rail 231. Thereafter, the first drive device 232 drives the relay rail 231 on which the sample rack is placed so that it is connected to the third supply end 241 of the third rail 24.

[0235] In step S80, the sample rack described above is transported from the relay rail 231 to the third supply end 241.

[0236] In this step, after the relay rail 231 on which the aforementioned sample rack is placed is connected to the third supply end 241 of the third rail 24, the relay rail 231 moves to transport the sample rack to the third supply end 241 of the third rail 24.

[0237] In step S90, the sample rack described above travels from the third supply end 241 to the third discharge end 242 of the third rail 24 and leaves the sample analyzer 100.

[0238] In this step, the relay rail 231 moves to transport the sample rack to the third supply end 241 of the third rail 24, and then the third rail 24 transports the sample rack away from the sample analyzer 100.

[0239] 5, in yet another aspect, the present application provides a sample collection method for the sample analyzer 100. The sample collection method includes the following steps.

[0240] In step S100, in the first sampling zone, the first sample adding mechanism transfers the sample in the sample container carried in the first sample rack into a reaction container placed on the reaction disk 10.

[0241] In this step, the sample analyzer 100 includes a reaction disk 10, a first rail 21, and a first sample addition mechanism. The first rail 21 and the first sample addition mechanism are provided on the outside of the reaction disk 10.

[0242] The first sampling zone is located on the first rail 21. The first sample addition mechanism is used to transfer a sample from a sample container held in a first sample rack located in the first sampling zone to a reaction container placed on the reaction disk 10, and to perform biochemical detection on the sample.

[0243] In step S200, in the second sampling zone, the second sample adding mechanism transfers the sample in the sample container carried in the second sample rack into the detection container carried in the electrolyte detection mechanism 30.

[0244] In this step, the sample analyzer 100 further includes a second rail 22 and a second sample addition mechanism, which are respectively provided on the outer side of the reaction disk 10. The second sampling zone is provided on the second rail 22.

[0245] The second sample addition mechanism and the first sample addition mechanism operate independently of each other. The second sample addition mechanism is used to transfer samples from sample containers held in a second sample rack located in the second sampling zone to detection containers held in the electrolyte detection mechanism 30, and then perform electrolyte detection on the samples.

[0246] In step S300, the second sample rack passes through the first sampling zone in the process of being transferred to the second sampling zone.

[0247] In this step, the second rail 22 and the first rail 21 are parallel to each other. The sample analyzer 100 further includes a sample rack transfer mechanism 23 for transferring the second sample rack from the first rail 21 to the second rail 22.

[0248] Specifically, the second sample rack enters the first rail 21 from the first supply end 212 of the first rail 21, and then the second sample rack moves along the first rail 21 to the first discharge end 213 of the first rail 21, and is transferred from the first discharge end 213 to the sample rack transfer mechanism 23.

[0249] Furthermore, in one embodiment, when the second sample rack reaches the first sampling zone, the first sample addition mechanism transfers the samples in the sample containers carried in the second sample rack to the reaction containers, while when the second sample rack reaches the second sampling zone, the second sample addition mechanism transfers the samples in the sample containers carried in the second sample rack to the detection containers.

[0250] Specifically, in this embodiment, the samples contained in the sample containers held in the second sample rack need to undergo both biochemical testing and electrolyte detection.

[0251] Therefore, after the second sample rack moves to the first sampling zone on the first rail 21, the first sample adding mechanism samples the second sample rack for biochemical testing.

[0252] When the first sample adding mechanism completes sampling, the second sample rack is transferred to the second rail 22 under the action of the sample rack transfer mechanism 23, and moves along the second rail 22 to the second sampling zone.

[0253] After the second sample rack reaches the second sampling zone, the second sample adding mechanism samples the sample rack for electrolyte detection.

[0254] Furthermore, after the first sample addition mechanism transfers the samples in the sample containers carried in the second sample rack to the aforementioned reaction containers, the second sample rack moves from the aforementioned first sampling zone to the first discharge end 213 of the first rail 21, and is transferred from the first discharge end 213 to the sample rack transfer mechanism 23.

[0255] Specifically, the sample rack transfer mechanism 23 includes a first drive device 232 and a relay rail 231. The first drive device 232 drives the relay rail 231 so that the relay rail 231 is connected to the first discharge end 213 of the first rail 21 and the input / output end 221 of the second rail 22, respectively.

[0256] After the relay rail 231 connects with the first discharge end 213 of the first rail 21, the first rail 21 moves to transport the second sample rack from the first sampling zone to the first discharge end 213 of the first rail 21, and then transfers it from the first discharge end 213 to the relay rail 231.

[0257] The sample rack transfer mechanism 23 transfers the second sample rack to the inlet / outlet end 221 of the second rail 22.

[0258] After the second sample rack is transferred to the relay rail 231, the first drive device 232 drives the relay rail 231 carrying the second sample rack so that it moves until it connects with the input / output end 221 of the second rail 22.

[0259] After the relay rail 231 is connected to the input / output end 221 of the second rail 22 , the relay rail 231 moves to transport the second sample rack to the input / output end 221 of the second rail 22 .

[0260] After the second sample rack reaches the second sampling zone from the input / output end 221, the second sample addition mechanism transfers the sample in the sample container placed by the second sample rack into the detection container placed by the electrolyte detection mechanism 30.

[0261] After the second sample rack is transported to the input / output end 221 of the second rail 22, the second rail 22 continues to transport the second sample rack to the second sampling zone so that the second sample addition mechanism can collect the sample required for electrolyte detection.

[0262] After the second sample addition mechanism transfers the sample in the sample container held in the second sample rack to the aforementioned detection container, the second sample rack reaches the aforementioned input / output end 221 from the second sampling zone and is transferred from the input / output end 221 to the sample rack transfer mechanism 23.

[0263] Specifically, when the second sample addition mechanism has completed collection of the sample required for electrolyte detection, the second sample rack moves on the second rail 22 to the input / output end 221 of the second rail 22.

[0264] After the second sample rack reaches the input / output end 221 of the second rail 22, the second rail 22 moves to transfer the second sample rack to the relay rail 231.

[0265] Furthermore, during the process of transferring the sample in the sample container carried in the second sample rack to the aforementioned detection container, the second sample rack is placed in the second sampling zone, so the second sample addition mechanism can move into a different sample container carried in the second sample rack to collect a sample.

[0266] In this embodiment, the sampling needle of the second sample addition mechanism described above can move into a different sample container carried by the second sample rack placed on the second rail 22 and perform sampling.

[0267] In one embodiment, the second sample application mechanism includes a collapsible arm and a sampling needle, the collapsible arm being capable of moving the sampling needle to collect a sample into a different sample container carried by the second sample rack.

[0268] Specifically, the folding arm includes at least a first sub-folding arm 422 and a second sub-folding arm 423. One end of the first sub-folding arm 422 is rotatably installed around a first rotation center 421, and the other end of the first sub-folding arm 422 is connected to one end of a second sub-folding arm 423. The second sub-folding arm 423 is rotatable relative to the first sub-folding arm 422. The other end of the second sub-folding arm 423 is connected to the sampling needle.

[0269] The sampling needle can be positioned on the folding arm so that the sampling needle can sample within a second sampling zone on the second rail 22. The second sampling zone can accommodate at least one second sample rack, allowing the sampling needle to sample from any sample container in the second sample rack placed in the second sampling zone.

[0270] In another embodiment, the second sample adding mechanism includes a telescopic arm and a sampling needle, and the telescopic arm can move the sampling needle to sample a sample in a different sample container carried by the second sample rack.

[0271] Specifically, the telescopic arm includes at least a first sub-telescopic arm and a second sub-telescopic arm. One end of the first sub-telescopic arm is rotatable around a first rotation center 421, and the other end of the first sub-telescopic arm is connected to one end of the second sub-telescopic arm. The second sub-telescopic arm is extendable and retractable relative to the first sub-telescopic arm. The other end of the second sub-telescopic arm is connected to the sampling needle.

[0272] By placing the sampling needle on the telescopic arm, the sampling needle can sample within a second sampling zone on the second rail 22. Because the second sampling zone can accommodate at least one second sample rack, the sampling needle can sample from any sample container in the second sample rack placed in the second sampling zone.

[0273] Furthermore, in the process of transferring the samples in the sample containers held in the first sample rack to the reaction containers, the sample containers held in the first sample rack sequentially pass through a common sampling point 211 located in the first sampling zone, and the first sample addition mechanism sequentially transfers the samples in the sample containers located at the common sampling point 211 to the reaction containers.

[0274] In one embodiment, the first sample addition mechanism includes a first sample addition arm 411 and a second sample addition arm 412 that are independent of each other.

[0275] The reaction disk 10 includes an outer reaction tray 11 and an inner reaction tray 12 provided inside the outer reaction tray 11. The first sample addition mechanism includes a first sample addition arm 411 and a second sample addition arm 412. Both the first sample addition arm 411 and the second sample addition arm 412 perform sampling at the common sampling point 211 in the first sampling zone. The first sample rack moves on the first rail 21 so that each sample container in the first sample rack reaches the common sampling point 211.

[0276] Specifically, the movement trajectory of the sampling needle of the first sample addition arm 411 and the movement trajectory of the sampling needle of the second sample addition arm 412 each intersect with the aforementioned common sampling point 211 on the first rail 21 so that the sampling needle of the first sample addition arm 411 and the sampling needle of the second sample addition arm 412 both sample at the aforementioned common sampling point 211.

[0277] For the double-ring structured reaction disk 10, the sampling needle of the first sample addition arm 411 can be used to transfer the sample collected at the common sampling point 211 into a reaction vessel placed on the reaction inner tray 12 or the reaction outer tray 11. The sampling needle of the second sample addition arm 412 can also be used to transfer the sample collected at the common sampling point 211 into a reaction vessel placed on the reaction inner tray 12 or the reaction outer tray 11.

[0278] Preferably, the sampling needle of the first sample addition arm 411 is used to transfer the sample collected at the common sampling point 211 into a reaction vessel placed on the inner reaction tray 12, and the sampling needle of the second sample addition arm 412 is used to transfer the sample collected at the common sampling point 211 into a reaction vessel placed on the outer reaction tray 11.

[0279] Furthermore, the first rotation center 421 and the second rotation center 413 are provided on both sides of the vertical symmetry line 104. The third rotation center 414 and the second rotation center 413 are located on the same side of the vertical symmetry line 104. This allows the first sample addition mechanism and the second sample addition mechanism to be disposed on both sides of the vertical symmetry line 104. Therefore, the first sample addition mechanism and the second sample addition mechanism can avoid interfering with each other when injecting a sample for biochemical testing and a sample for electrolyte detection, respectively.

[0280] Furthermore, the second rotation center 413 is located between the first rotation center 421 and the third rotation center 414. Here, in one specific embodiment, the sampling needle of the first sample addition arm 411 is used to inject the sample in the sample container at the common sampling point 211 into a reaction container placed on the inner reaction tray 12, and the sampling needle of the second sample addition arm 412 is used to inject the sample in the sample container at the common sampling point 211 into a reaction container placed on the outer reaction tray 11.

[0281] For ease of description, spatially relative terms such as "above," "above," "on top of," "above," and "on top of" may be used herein to describe the spatial relationship of one element or feature to other elements or features shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of an element during use or operation other than the orientation depicted in the figures. For example, if an element in the figures is inverted, an element described as "above other elements or structures" or "on top of other elements or structures" would then be positioned as "below other elements or structures" or "beneath other elements or structures." Thus, the exemplary term "above" can encompass two orientations: "above" and "below." The element may also be positioned in other different ways (rotated 90 degrees or at other orientations) and receive corresponding interpretations of the spatially relative descriptions used herein.

[0282] Furthermore, the use of terms such as "first" and "second" to limit parts is merely to make it easier to distinguish the relevant parts, and unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present application.

[0283] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Those skilled in the art may find various modifications and variations in the present application.
