Description

Technical Field

[0001] The present application relates to the technical field of biological sample preprocessing, and in particular to a biological sample centrifugation module. Background Art

[0002] Biological sample analysis has become an indispensable technical means in disease diagnosis. With the increasing demand for biological sample analysis, biological sample analysis has been upgraded from manual processing to automated processing. In automated processing, some biological samples need to be transported to the centrifugal module via a track for centrifugal processing, so that the biological samples are separated to obtain the detection target.

[0003] Compared with independent centrifugal devices, biological sample centrifugal modules in assembly line mode or online mode need to cooperate with other functional modules (such as detection modules, sample supply modules, etc.) to perform joint processing of samples. Since the centrifugation of biological samples is usually batch processing, the samples before centrifugation usually need to be transferred one by one from the assembly line (track) and placed in batches into the centrifugal device for centrifugation. After centrifugation, the batch samples need to be transferred back to the assembly line (track) one by one. Therefore, the transfer efficiency of biological samples before and after centrifugation will affect the efficiency of the centrifugal module.

[0004] In the prior art, the centrifugal module adopts a single transfer mechanism to perform the sample transfer work during the centrifugation process. The transfer mechanism can only transfer samples from the assembly line (track) into the centrifugal device or from the centrifugal device out of the assembly line (track) within a time period, resulting in that when the sample is transferred in, the sample to be transferred out to the assembly line (track) is in a waiting state, or when the sample is transferred out, the sample to be transferred into the centrifugal device is in a waiting state, thereby causing the samples to be centrifuged to accumulate on the assembly line (track), or the samples transferred out of the centrifugal device to accumulate in the centrifugal module, and the carrier used to carry the transferred samples to accumulate on the assembly line (track), thereby affecting the centrifugal efficiency of the sample.

[0068] See also Figure 1-6As shown, the present application provides a biological sample centrifugal module, including a centrifugal device 10, a first transfer mechanism 20 and a second transfer mechanism 30. The centrifugal device 10 is used to centrifuge a sample. The first transfer mechanism 20 can be used to transfer a sample container containing a sample to be centrifuged into the centrifugal device 10. The second transfer mechanism 30 is arranged on the side of the first transfer mechanism 20, and the second transfer mechanism 30 can be used to transfer the sample container containing the sample out of the centrifugal device 10.

[0069] In this embodiment, the sample container containing the sample to be centrifuged is transferred to the centrifuge device 10 by the first transfer mechanism 20, and the sample container in the centrifuge device 10 is transferred out of the centrifuge device 10 by the second transfer mechanism 30. Therefore, in the same time period, while the first transfer mechanism 20 transfers the sample to be centrifuged into the centrifuge module, the second transfer mechanism 30 can transfer the sample transferred out of the centrifuge device 10 away from the centrifuge module, thereby effectively solving the problem of affecting the centrifugation efficiency of the sample caused by the accumulation of biological samples.

[0070] In one embodiment, the biological sample centrifugation module is disposed on one side of a sample transport track 100 , and the sample transport track 100 is used for movement of a carrier 300 , and the carrier 300 is used to carry the sample container so that the carried sample container is transported along the sample transport track 100 .

[0071] The first transfer mechanism 20 may be used to transfer the sample container containing the sample to be centrifuged from the carrier 300 located on the sample transport track 100 to the centrifugal device 10 .

[0072] The second transfer mechanism 30 may be used to transfer the sample container out of the centrifugal device 10 and place the sample container in the carrier 300 that is located on the sample transport track 100 and does not carry the sample container.

[0073] In another embodiment, the sample container can move directly on the sample transport track 100. That is, the sample transport track 100 has a plurality of carrying positions, and each of the carrying positions can be used to carry one sample container.

[0074] By transporting the sample container via the sample transport track 100 , the sample can be further automatically transported into and out of the biological sample centrifugation module, thereby improving the transport efficiency of the sample before and after centrifugation.

[0075] Furthermore, the sample container is carried by the adapter 200 to be placed in the centrifugal device 10 for centrifugal treatment, and the adapter 200 can carry multiple sample containers. The first transfer mechanism 20 is used to transfer the sample container carrying the sample to be centrifuged into the adapter 200, and transfer the adapter 200 after balancing into the centrifugal device 10, and the second transfer mechanism 30 is used to transfer the adapter 200 out of the centrifugal device 10, and transfer the sample container out of the adapter 200 and place it in the carrier 300 located on the sample conveying track 100 and not carrying the sample container.

[0076] Further, the first transfer mechanism 20 has a first working area 40, and the second transfer mechanism 30 has a second working area 50. The first working area 40 and the second working area 50 partially overlap to form a common working area 60. Through the setting of the common working area 60, the space of the centrifugal module is compact, the overall operation of the centrifugal process is more centralized, and the operation time is saved. The first working area 40 includes the common working area 60 and the balancing area 41, and the second working area 50 includes the common working area 60 and the unloading area 51. The centrifugal device 10 is arranged in the common working area 60. Therefore, both the first transfer mechanism 20 and the second transfer mechanism 30 can perform the transfer operation of the adapter 200 in the common working area 60.

[0077] The first transfer mechanism 20 can be used to transfer the sample container carried on the carrier 300 to the adapter 200 located in the balancing area 41 , and transfer the adapter 200 after successful balancing in the balancing area 41 to the centrifugal device 10 .

[0078] The second transfer mechanism 30 can be used to transfer the adapter 200 from the centrifugal device 10 to the unloading area 51, and transfer the sample container in the adapter 200 located in the unloading area 51 out and place it in the carrier 300 that does not carry the sample container.

[0079] During the centrifugation of the centrifuge device 10, the first transfer mechanism 20 can continue to transfer the next batch of samples to be centrifuged to the adapter 200 located in the balancing area 41 for balancing, and the second transfer mechanism 30 can transfer the sample container in the adapter 200 transferred from the centrifuge device 10 to the unloading area 51 out of the adapter 200 and place it in the carrier 300 located on the sample conveying track 100 that does not carry the sample container.

[0080] Through the cooperation of the first transfer mechanism 20, the second transfer mechanism 30 and the centrifugal device 10, corresponding centrifugal process operations can be performed on different batches of samples in the same time period, thereby effectively solving the problem of biological sample accumulation affecting the centrifugal efficiency of the samples.

[0081] In one embodiment, the first transfer mechanism 20 and / or the second transfer mechanism 30 is a robot, and both the first transfer mechanism 20 and the second transfer mechanism 30 can clamp and transfer the sample container and the adapter 200 .

[0082] In another embodiment, the first transfer mechanism 20 and / or the second transfer mechanism 30 are both mobile mechanisms capable of three-dimensional motion along the XYZ directions, and both the first transfer mechanism 20 and the second transfer mechanism 30 can clamp and transfer the sample container and the adapter 200 .

[0083] Furthermore, the balancing area 41 and the unloading area 51 are located at opposite sides of the common working area 60. The biological sample centrifugal module is disposed on the side of the sample conveying track 100 along the direction from the balancing area 41 to the unloading area 51.

[0084] Furthermore, the balancing area 41 is provided with a plurality of balancing positions 411 , each of the balancing positions 411 is provided with a weight sensing device 90 , and each of the weight sensing devices 90 can carry an adapter 200 and sense the weight of the carried adapter 200 .

[0085] The first transfer mechanism 20 is used to transfer the sample containers carried in the carrier 300 on the feed track 70 to the adapters 200 one by one, so as to achieve balancing of the plurality of adapters 200 .

[0086] In one embodiment, the balancing area 41 has four balancing positions 411, each of which can be used to place a weight sensing device 90, each of which can be used to place an adapter 200, and the first transfer mechanism 20 can grab and transfer a sample container to any of the adapters 200 at a time. Preferably, the four balancing positions 411 are arranged in a square array.

[0087] Among them, the first transfer mechanism 20 can place the captured sample containers in different adapters 200 in sequence. For example, the first sample container captured by the first transfer mechanism 20 can be placed in the first adapter 200, the second sample container captured by the first transfer mechanism 20 can be placed in the second adapter 200, the third sample container captured by the first transfer mechanism 20 can be placed in the third adapter 200, and the fourth sample container captured by the first transfer mechanism 20 can be placed in the fourth adapter 200. By placing different sample containers in different adapters 200 in sequence, real-time balancing of the sample containers placed in the adapters 200 can be achieved, thereby improving the balancing efficiency and effectively reducing the risk of balancing failure.

[0088] Furthermore, in this embodiment, the first adapter 200 and the second adapter 200 are arranged diagonally, and the third adapter 200 and the fourth adapter 200 are arranged diagonally; or the first adapter 200 and the third adapter 200 are arranged diagonally, and the second adapter 200 and the fourth adapter 200 are arranged diagonally.

[0089] Furthermore, when the centrifugal device 10 centrifuges the sample carried in the adapter 200, the first transfer mechanism 20 can transfer the sample container containing the sample to be centrifuged from the carrier 300 on the sample conveying track 100 to the adapter 200 located in the balancing area 41 for balancing, and the second transfer mechanism 30 can transfer the sample container carried in the adapter 200 located in the unloading area 51 to the sample conveying track 100, thereby effectively improving the centrifugal efficiency of the centrifugal module.

[0090] Furthermore, the first working area 40 further includes a first buffer area 42, which is located on a side of the trimming area 41 away from the sample conveying track 100 and is used to buffer the adapter 200 that does not carry the sample container. When there is no vacancy in the trimming area 41, the adapter 200 that returns to the trimming area 41 from the unloading area 51 will be temporarily stored in the first buffer area 42, so that when there is a vacancy in the trimming area 41, it can be transferred by the first transfer mechanism 20 and placed in the vacancy.

[0091] Furthermore, the second working area 50 also includes a second buffer area 52, which is located on a side of the unloading area 51 away from the sample conveying track 100 and can be used to cache the adapter 200 carrying the sample container or the adapter 200 not carrying the sample container.

[0092] By providing the first buffer area 42 and the second buffer area 52, the turnover number of the adapter 200 in the biological sample centrifugation module can be increased, thereby improving the sample throughput in the biological sample centrifugation module and further improving the centrifugation efficiency of the sample.

[0093] When the adapter 200 without the sample container appears in the unloading area 51, and there is no placement position for the adapter 200 in the balancing area 41 and the first buffer area 42, the second transfer mechanism 30 will transfer the adapter 200 in the unloading area 51 to the second buffer area 52 for temporary storage; or, when there is no empty position in the unloading area 51 and the centrifugal device 10 completes the centrifugal treatment, the second transfer mechanism 30 will transfer the adapter 200 in the centrifugal device 10 to the second buffer area 52 for temporary storage, and when an empty unloading position 511 appears in the unloading area 51, the adapter 200 will be transferred from the second buffer area 52 to the empty unloading position 511.

[0094] Further, the common working area 60 includes an adapter transfer area 61 and a centrifuge inlet and outlet 62. The adapter 200 enters and exits the centrifuge device 10 through the centrifuge inlet and outlet 62, and the adapter transfer area 61 is located on a side of the centrifuge inlet and outlet 62 away from the sample conveying track 100, and the adapter transfer area 61 is used to transfer the adapter 200. The adapter 200 may or may not carry the sample container.

[0095] When the adapter 200 from which the sample container has been unloaded by the second transfer mechanism 30 is to be returned to the balancing area 41 or the first buffer area 42, the second transfer mechanism 30 first transfers the adapter 200 to the adapter transfer area 61, and then the first transfer mechanism 20 transfers the adapter 200 from the adapter transfer area 61 to the balancing area 41 or the first buffer area 42.

[0096] Further, the adapter transfer area 61 includes a first transfer area 611 and a second transfer area 612 , the first transfer area 611 is close to the centrifugal inlet and outlet 62 , and the second transfer area 612 is far away from the centrifugal inlet and outlet 62 .

[0097] The first transfer area 611 and the second transfer area 612 can both be used to transfer the adapter 200 that is not carrying the sample container and is returned from the unloading area 51 or the second buffer area 52 to the trimming area 41 or the first buffer area 42. That is, the second transfer mechanism 30 can transfer the empty adapter 200 in the second buffer area 52 or the unloading area 51 to the first transfer area 611 or the second transfer area 612, and the first transfer mechanism 20 can transfer the adapter 200 from the first transfer area 611 or the second transfer area 612 to the trimming area 41 or the first buffer area 42.

[0098] The second transfer area 612 can also be used to transfer the adapter 200 that has failed to be balanced and transferred from the balancing area 41 to the unloading area 51. That is, when the adapter 200 in the balancing area 41 fails to be balanced, the first transfer mechanism 20 first transfers the adapter 200 to the second transfer area 612, and the second transfer mechanism 30 then transfers the adapter 200 to the unloading area 51 and unloads the samples in the adapter 200 one by one and transfers them to the carrier 300 on the discharge track 80.

[0099] By setting up the first transfer area 611 and the second transfer area 612 for transferring the adapter 200, not only can the first transfer mechanism 20 and the second transfer mechanism 30 be prevented from interfering when transferring the adapter 200, but also when an abnormality occurs, the scheduling of the adapter 200 between the first working area 40 and the second working area 50 will not be affected.

[0100] For further information, see Figure 5-6 Combined with Figure 1 As shown, the first working area 40 is located on a first horizontal plane, the second working area 50 is located on a second horizontal plane, and the centrifugal device 10 is located below the first horizontal plane and the second horizontal plane. The first horizontal plane and the second horizontal plane can be a uniform horizontal plane.

[0101] By sinking the centrifugal device 10 below the first working area 40 and the second working area 50, the space below the first working area 40 and the second working area 50 can be fully utilized to install the centrifugal device 10, thereby achieving a more compact spatial arrangement and a more reasonable spatial layout of the biological sample centrifugal module.

[0102] In one embodiment, the common working area 60 is provided with only one centrifuge inlet and outlet 62, and the centrifuge inlet and outlet 62 only allows one adapter 200 to be placed in or out of the centrifuge device 10 at a time. The centrifuge device 10 has a plurality of centrifuge working positions 11, and one centrifuge working position 11 can carry one adapter 200, and a plurality of centrifuge working positions 11 can pass through the centrifuge inlet and outlet 62 in sequence.

[0103] By providing only one centrifugal inlet and outlet 62, the area of ​​the common working area 60 can be further compressed, thereby further reasonably compressing the space occupied by the biological sample centrifugal module.

[0104] In another embodiment, the centrifuge inlet and outlet 62 includes a first inlet and outlet 621 and a second inlet and outlet that are independent of each other. Both the first inlet and outlet 621 and the second inlet and outlet can be used to allow the adapter 200 to enter or leave the centrifuge device 10 .

[0105] The centrifugal device 10 has a plurality of centrifugal working positions 11 , one of the centrifugal working positions 11 can carry one of the adapters 200 , and a plurality of the centrifugal working positions 11 can sequentially pass through the first inlet and outlet 621 and the second inlet and outlet.

[0106] Furthermore, when the first transfer mechanism 20 transfers the adapter 200 at one of the first inlet and outlet 621 or the second inlet and outlet, the second transfer mechanism 30 may transfer the adapter 200 at the other of the first inlet and outlet 621 or the second inlet and outlet.

[0107] Furthermore, when the first transfer mechanism 20 places one of the adapters 200 into the corresponding centrifuge working position 11 from the first inlet and outlet 621, the second transfer mechanism 30 can transfer the adapter 200 on another centrifuge inlet and outlet position out of the centrifuge device 10 from the second inlet and outlet.

[0108] When the first transfer mechanism 20 places one of the adapters 200 into the corresponding centrifugal working position 11 from the second inlet and outlet, the second transfer mechanism 30 can transfer the adapter 200 on another centrifugal inlet and outlet position out of the centrifugal device 10 from the first inlet and outlet 621 .

[0109] By providing the first inlet and outlet 621 and the second inlet and outlet, the space occupied by the biological sample centrifugal module can be reasonably compressed, and the transfer efficiency of the carrier 300 in and out of the centrifugal device 10 can be more efficiently achieved.

[0110] Furthermore, the biological sample centrifugal module further includes a feed track and a discharge track 80. The feed track is disposed between the sample conveying track 100 and the trimming area 41, and the carrier 300 carrying the sample container on the sample conveying track 100 can enter the feed track, the first transfer mechanism 20 can be used to transfer the sample container from the feed track and place it in the adapter 200 located in the trimming area 41, and the carrier 300 with the sample container transferred away can return from the feed track to the sample conveying track 100.

[0111] The unloading track 80 is located between the sample conveying track 100 and the unloading area 51, and the carrier 300 on the sample conveying track 100 that does not carry the sample container can enter the unloading track 80, the second transfer mechanism 30 can rotate the adapter 200 located in the unloading area 51 out and place it in the carrier 300 on the unloading track 80 that does not carry the sample container, and the carrier 300 carrying the sample container can return from the unloading track 80 to the sample conveying track 100.

[0112] By providing an independent feed track 70 for movement of the carrier 300 carrying the sample container, and providing an independent discharge track 80 for movement of the carrier 300 not carrying the sample container, the first transfer mechanism 20 can process the sample to be centrifuged independently from the second transfer mechanism 30 processing the sample after centrifugation, thereby effectively improving the sample container transfer efficiency of the first transfer mechanism 20 and the second transfer mechanism 30.

[0113] For further information, see Figure 4 As shown, each of the adapters 200 is structured to have a plurality of sample container accommodating positions, each of which can carry a sample container. The adapter 200 also includes a handle 210, and the first transfer mechanism 20 or the second transfer mechanism 30 can grasp the adapter 200 by grasping the handle 210 to facilitate the transfer of the adapter 200.

[0114] Furthermore, the second transfer mechanism 30 is used to transfer the adapter 200 from the centrifuge 10 to the unloading area 51 , and to transfer the sample container carried in the adapter 200 located in the unloading area 51 to the carrier 300 on the discharge track 80 .

[0115] Furthermore, the unloading area 51 includes a plurality of unloading positions 511 , and each of the unloading positions 511 can accommodate one of the adapters 200 .

[0116] In the first case, the second transfer mechanism 30 is used to transfer the adapter 200 after centrifugation in the centrifuge device 10 to the unloading area 51, and transfer the sample containers containing the centrifuged samples one by one from the adapter 200 to the adapter 200 on the discharge track 80 that does not carry the sample containers, and transport them downstream through the adapter 200.

[0117] In the second case, the second transfer mechanism 30 is used to transfer the samples with centrifugal abnormality caused by centrifugation failure in the centrifuge device 10 to the unloading area 51, and transfer the sample containers containing the centrifugation failed samples one by one from the adapter 200 to the adapter 200 on the discharge track 80 that does not carry the sample containers, and transport them downstream through the adapter 200.

[0118] In the third case, when balancing fails in the balancing area 41, the first transfer mechanism 20 transfers the adapter 200 carrying the sample container that failed balancing to the common working area 60, and the second transfer mechanism 30 transfers the adapter 200 from the common working area 60 to the unloading area 51, and transfers the sample containers containing the samples that failed balancing one by one from the adapter 200 to the adapter 200 that does not carry the sample containers on the discharge track 80, and transports them downstream through the adapter 200.

[0119] Further, the feed track 70 includes a first feed end 71, a feed grabbing position 72 and a first discharge end 73. The feed grabbing position 72 is located between the first feed end 71 and the first discharge end 73.

[0120] The carrier 300 carrying the sample container on the sample conveying track 100 can enter the feed track 70 from the first feed end 71, and move along the feed track 70 to the feed grabbing position 72. The first transfer mechanism 20 can grab the sample container carried by the carrier 300 located at the feed grabbing position 72 and transfer it to the adapter 200. The carrier 300 with the sample container grabbed can continue to move along the feed track 70 to the first discharge end 73, and move from the first discharge end 73 to the sample conveying track 100.

[0121] The discharge track 80 includes a second feed end 81, a discharge layout position 82 and a second discharge end 83. The discharge layout position 82 is located between the second feed end 81 and the second discharge end 83.

[0122] The carrier 300 on the sample conveying track 100 that does not carry the sample container can enter the discharge track 80 from the second feed end 81 and move along the discharge track 80 to the discharge placement position 82. The second transfer mechanism 30 can transfer a sample container and place it into the carrier 300 located at the discharge placement position 82. The carrier 300 carrying the sample container can continue to move along the discharge track 80 to the second discharge end 83 and move from the second discharge end 83 to the sample conveying track 100.

[0123] Furthermore, the discharge track 80 is located downstream of the feed track 70. The carrier 300 after grabbing the sample container can enter the discharge track 80 through the sample conveying track 100, and carry the sample container transferred from the adapter 200 by the second transfer mechanism 30 at the discharge placement position 82, and convey the sample container to the sample conveying track 100.

[0124] That is to say, after the sample container is grabbed by the first transfer mechanism 20 at the feed grabbing position 72, the carrier 300 carrying the sample container will enter the sample conveying track 100 from the first discharge end 73 of the feed track 70, and can enter the discharge track 80 from the second feed end 81. When the carrier 300 moves to the discharge sampling position 82, the second transfer mechanism 30 can transfer the sample in the adapter 200 located in the unloading area 51 to the carrier 300, so that the sample continues to move downstream through the carrier 300.

[0125] Furthermore, the biological sample centrifuge module further includes a first transfer tray 74 and a second transfer tray 84. The first transfer tray 74 and the second transfer tray 84 separate the sample transport track 100 into a first track section 101, a second track section 102 and a third track section 103. The second track section 102 is between the first transfer tray 74 and the second transfer tray 84.

[0126] The first transfer plate 74 is used to transfer the carrier 300 between the first section track 101 , the feed track 70 and the second section track 102 , and the second transfer plate 84 is used to transfer the carrier 300 between the second section track 102 , the discharge track 80 and the third section track 103 .

[0127] Furthermore, the first transfer disc 74 is configured to form a first transfer slot 741 , and the first transfer disc 74 rotates so that the first transfer slot 741 has a first feed position, a second feed position, a first discharge position, and a second discharge position.

[0128] When the first transfer slot 741 is at the first feeding position, the outlet of the first section track 101 is connected to the first transfer slot 741 so that the carrier 300 carrying the sample container on the first section track 101 can enter the first transfer slot 741; when the first transfer disk 74 rotates so that the first transfer slot 741 is at the first discharging position, the first transfer slot 741 is connected to the first feeding end 71 of the feeding track 70 so that the carrier 300 in the first transfer slot 741 can enter the feeding track 70; or, when the first transfer disk 74 rotates so that the first transfer slot 741 is at the second discharging position, the first transfer slot 741 is connected to the second section track 102 so that the carrier 300 in the first transfer slot 741 can enter the second section track 102, thereby allowing the carrier 300 on the first section track 101 to pass over the first transfer disk 74 and enter the second section track 102.

[0129] When the first transfer groove 741 is in the second feeding position, the first discharge end 73 of the feed track 70 is connected with the first transfer groove 741 so that the carrier 300 on the feed track 70 can enter the first transfer groove 741; when the first transfer disk 74 rotates so that the first transfer groove 741 is in the second discharge position, the first transfer groove 741 is connected with the second section track 102 so that the carrier 300 in the first transfer groove 741 can enter the second section track 102, thereby allowing the carrier 300 on the first section track 101 to pass over the first transfer disk 74 and enter the second section track 102.

[0130] By setting the first transfer groove 741 on the first transfer disk 74 for transferring the carrier 300 between the sample conveying track 100 and the feed track 70, it is possible to avoid setting up a robot or a three-dimensional transfer mechanism to transfer the carrier 300 between the sample conveying track 100 and the feed track 70, thereby ensuring efficient transfer of the carrier 300 between the sample conveying track 100 and the feed track 70.

[0131] Further, the second transfer disc 84 is structured to form a second transfer groove 841, and the second transfer disc 84 rotates so that the second transfer groove 841 has a third feeding position, a fourth feeding position, a third discharging position and a fourth discharging position.

[0132] When the second transfer slot 841 is at the third feeding position, the outlet of the second track 102 is connected to the second transfer slot 841 so that the carrier 300 carrying the sample container on the second track 102 can enter the second transfer slot 841; when the second transfer disk 84 rotates so that the second transfer slot 841 is at the third discharging position, the second transfer slot 841 is connected to the second feeding end 81 of the discharging track 80 so that the carrier 300 in the second transfer slot 841 can enter the discharging track 80; or, when the second transfer disk 84 rotates so that the second transfer slot 841 is at the fourth discharging position, the second transfer slot 841 is connected to the third track 103 so that the carrier 300 in the second transfer slot 841 can enter the third track 103, thereby allowing the carrier 300 on the second track 102 to pass over the second transfer disk 84 and enter the third track 103.

[0133] When the second transfer groove 841 is in the fourth feeding position, the second discharge end 83 of the discharge track 80 is connected with the second transfer groove 841 so that the carrier 300 on the discharge track 80 can enter the second transfer groove 841; when the second transfer disk 84 is rotated so that the second transfer groove 841 is in the fourth discharge position, the second transfer groove 841 is connected with the third section track 103 so that the carrier 300 in the second transfer groove 841 can enter the third section track 103, thereby allowing the carrier 300 on the second section track 102 to pass over the second transfer disk 84 and enter the third section track 103.

[0134] By setting the second transfer groove 841 on the second transfer disk 84 for transferring the carrier 300 between the sample conveying track 100 and the discharge track 80, it is possible to avoid setting up the robot or the three-dimensional transfer mechanism to transfer the carrier 300 between the sample conveying track 100 and the discharge track 80, thereby ensuring efficient transfer of the carrier 300 between the sample conveying track 100 and the discharge track 80.

[0135] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0136] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
