[0033] In the following description, specific details are set forth in order to provide a thorough understanding of the present application. However, persons of ordinary skill in the art will realize that the present application can be practiced without many of the specific details given.

[0036] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a first embodiment of a reagent moving device of the application, Figure 2 is Figure 1 is a structural schematic diagram of another view of the reagent moving device in the application. The reagent moving device 1 provided by the embodiment of the application is used for reagent bottle sampling in a sample analyzer, which includes a bearing seat 11, a sliding assembly 12, an elastic assembly 13 and a fixing assembly 14.

[0037] The bearing seat 11 is used for loading a reagent bottle 2, for example but not limited to, the bearing seat 11 can load a first reagent bottle 21 and a second reagent bottle 22. The bearing seat 11 is arranged on the sliding assembly 12, and the sliding assembly 12 is used for driving the bearing seat 11 to move, so that the bearing seat 11 has a first state of being located in the sample analyzer and a second state of being located outside the sample analyzer.

[0038] In an embodiment, the reagent type loaded in the first reagent bottle 21 and the reagent type loaded in the second reagent bottle 22 can be the same, so as to increase the amount of reagents present in the carrier seat 11 at one time and improve the sample feeding efficiency of the reagent moving device 1. Alternatively, the reagent type loaded in the first reagent bottle 21 and the reagent type loaded in the second reagent bottle 22 can be different, so as to provide different types of reagents for the sample analyzer, meet the sample detection requirements of the sample analyzer, improve the detection efficiency of the sample analyzer, and improve the practicability of the reagent moving device 1.

[0039] Specifically, when the carrier seat 11 is in the second state located outside the sample analyzer, the user can replace the reagent bottle 2 on the carrier seat 11 to provide a new reagent bottle 2 for the sample analyzer. After the reagent bottle 2 on the carrier seat 11 is replaced, the carrier seat 11 is moved by the sliding assembly 12 and switched from the second state to the first state located inside the sample analyzer. At this time, the detection device inside the sample analyzer can use the sample liquid reacted with the reagent in the reagent bottle 2 on the carrier seat 11 in the first state for sample detection.

[0040] The elastic assembly 13 is arranged inside the sample analyzer and abuts against the sliding assembly 12. The sliding assembly 12 is used to compress the elastic assembly 13 when the carrier seat 11 is switched from the second state to the first state. The elastic assembly 13 is used to push the sliding assembly 12 when the carrier seat 11 is switched from the first state to the second state. The fixed assembly 14 is arranged in a spaced manner with the sliding assembly 12 and is used to fix the sliding assembly 12 when the carrier seat 11 is in the first state.

[0041] In the process of moving the carrier seat 11 from the second state to the first state by the sliding assembly 12, the sliding assembly 12 abuts against the elastic assembly 13. Therefore, in the process of moving the carrier seat 11 by the sliding assembly 12, the elastic assembly 13 is compressed. When the carrier seat 11 is in the first state, the compression amount of the elastic assembly 13 by the sliding assembly 12 is the largest. At this time, the fixed assembly 14 fixes the sliding assembly 12, so as to avoid the counter-compression force (the force generated when returning to the original shape) of the elastic assembly 13 pushing the sliding assembly 12 to move, so that the carrier seat 11 is switched from the first state to the second state. The stability of the carrier seat 11 in the first state is ensured. In the process of extracting the reagent in the reagent bottle on the carrier seat 11 by the detection device inside the sample analyzer, the elastic assembly 13 pushes the sliding assembly 12, and the carrier seat 11 drives the reagent bottle to move, so as to avoid damaging the components of the detection device. The practicability and safety of the reagent moving device are improved, and the operation efficiency of the sample analyzer is improved.

[0042] In an embodiment, during the process of switching the carrier seat 11 from the second state to the first state, the user can manually push the sliding assembly 12, and during the process, the elastic assembly 13 is compressed.

[0043] Further, when the reagent in the reagent bottle 2 on the carrier seat 11 in the first state is insufficient, the reagent bottle 2 on the carrier seat 11 needs to be replaced, at this time, the fixing assembly 14 releases the fixing of the sliding assembly 12, and due to the absence of the fixing force provided by the fixing assembly 14, the sliding assembly 12 is pushed away from the inside of the sample analyzer under the action of the counter-compression force of the elastic assembly 13, the carrier seat 11 is switched from the first state to the second state, and the user can replace the reagent bottle 2 on the carrier seat 11 in the second state.

[0044] Through the setting of the elastic assembly 13, the reagent moving device 1 provided by the embodiment of the present application does not need to set a motor to drive the movement of the sliding assembly 12 and the carrier seat 11, reduces energy consumption, reduces the occupied space of the reagent moving device 1 in the sample analyzer, improves the adaptability of the reagent moving device 1 to the sample analyzer, improves the practicability of the reagent moving device 1, and improves the user experience of the reagent moving device 1.

[0045] Meanwhile, the reagent bottles 2 loaded on the carrier seat 11 can at least include a first reagent bottle 21 and a second reagent bottle 22, which improves the sampling efficiency of the carrier seat 11 in the reagent bottle sampling process, and further improves the operation efficiency of the reagent moving device 1.

[0046] Optionally, please continue to refer to Figure 3 , Figure 3 is a structural schematic diagram of the second embodiment of the reagent moving device of the present application. The sliding assembly 12 includes a sliding bracket 121 and a guide slide rail 122, and the reagent moving device 1 further includes a mounting seat 15.

[0047] Among them, the mounting seat 15 is fixed in the sample analyzer, the guide slide rail 122 is installed on the mounting seat 15, the first end of the elastic assembly 13 is arranged on the mounting seat 15, the sliding bracket 121 is slidably arranged on the guide slide rail 122, and the second end of the elastic assembly 13 abuts against the sliding bracket 121.

[0048] Specifically, as shown in Figure 3 , when the carrier seat 11 is in the second state, there is a certain distance between the carrier seat 11 and the mounting seat 15, and as shown in Figure 1As shown, when the carrier 11 is in the first state, the carrier 11 is located directly above the mounting base 15. During the process of switching the carrier 11 from the second state to the first state, the sliding bracket 121 slides on the guide rail 122, and since the first end of the elastic assembly 13 is arranged on the mounting base 15, the second end of the elastic assembly 13 abuts against the sliding bracket 121, so that during the process of the sliding bracket 121 sliding along the guide rail 122 to approach the mounting base 15, the sliding bracket 121 compresses the elastic assembly 13 through the second end of the elastic assembly 13, and when the sliding bracket 121 drives the carrier 11 to switch to the first state and is located directly above the mounting base 15, the compression amount of the sliding bracket 121 to the elastic assembly 13 is the largest, and the fixing assembly 14 fixes the sliding bracket 121.

[0049] When it is necessary to replace the reagent bottle 2 on the carrier 11, the fixing assembly 14 withdraws the force for fixing the sliding bracket 121, and the elastic assembly 13 restores the original shape to exert a force on the sliding bracket 121 to move away from the mounting base 15, and under the action of the force provided by the elastic assembly 13, the sliding bracket 121 moves away from the mounting base 15 along the guide rail 122 to drive the carrier 11 to switch from the first state to the second state, so as to facilitate the user to replace the reagent bottle 2 on the carrier 11 and improve the practicability of the reagent moving device 1.

[0050] Optionally, the guide rail 122 includes a first rail 1221 and a second rail 1222, the first rail 1221 and the second rail 1222 are arranged in parallel, the first rail 1221 is arranged on the mounting base 15, and the second rail 1222 is arranged on the first rail 1221 in a sliding manner, and the sliding bracket 121 is arranged on the second rail 1222.

[0051] Specifically, as described above, during the process of switching the carrier 11 from the second state to the first state, the user can manually push the sliding bracket 121, so that during the process of switching the carrier 11 from the second state to the first state, the user can exert a force on the sliding bracket 121 to approach the mounting base 15 to push the sliding bracket 121 to move from the first end of the second rail 1222 to the second end of the second rail 1222, and the user can continue to push the sliding bracket 121, and since the sliding bracket 121 is located at the second end of the second rail 1222, the sliding bracket 121 cannot continue to slide along the second rail 1222, so that the second rail 1222 moves from the first end of the first rail 1221 to the second end of the first rail 1221 under the action of the force to drive the sliding bracket 121 to move to approach the mounting base 15 (in this process, the sliding bracket 121 is relatively stationary relative to the second rail 1222), and when the second rail 1222 moves to the second end of the first rail 1221, the carrier 11 is located directly above the mounting base 15, and the carrier 11 is switched to the first state.

[0052] In the process of switching the bearing seat 11 from the first state to the second state, the elastic assembly 13 applies a force to the sliding bracket 121 away from the mounting seat 15, and the sliding bracket 121 slides from the second end of the second slide rail 1222 to the first end of the second slide rail 1222 under the action of the force. Since the sliding bracket 121 cannot continue to move along the second slide rail 1222 at this time, the second slide rail 1222 will move from the second end of the first slide rail 1221 to the first end of the first slide rail 1221 under the action of the force. When the second slide rail 1222 moves to the first end of the first slide rail 1221, the bearing seat 11 is switched to the second state.

[0053] Through the cooperation of the first slide rail 1221 and the second slide rail 1222, the occupied space of the guide slide rail 122 can be reduced while ensuring the sliding distance of the sliding bracket 121, the occupied volume of the reagent moving device 1 can be reduced, and the adaptability of the reagent moving device 1 can be further improved.

[0054] Optionally, the fixing assembly 14 includes an electromagnet 141, the electromagnet 141 is arranged in a spaced manner with the mounting seat 15, and the side close to the mounting seat 15 of the electromagnet 141 is provided with a moving shaft 142.

[0055] The side close to the electromagnet 141 of the sliding bracket 121 is provided with a fixed groove 123 and a guide surface (not shown in the figure), and the guide surface is located on the side close to the mounting seat 15 of the fixed groove 123. When the sliding bracket 121 drives the bearing seat 11 to switch to the first state, one end of the moving shaft 142 abuts against the guide surface, and the contact point of the guide surface moves into the fixed groove 123, so as to fix the sliding bracket 121.

[0056] Specifically, in the process of switching the bearing seat 11 from the second state to the first state, the moving shaft 142 is in the extended state, and there is a guide surface on the edge of the fixed groove 123 close to the mounting seat 15. Then, in the process of moving the sliding bracket 121 close to the mounting seat 15, the end surface of one end of the moving shaft 142 abuts against the guide surface, and as the sliding bracket 121 gradually moves close to the mounting seat 15, one end of the moving shaft 142 gradually retracts due to the action of the guide surface. One end of the moving shaft 142 moves along the guide surface in the opposite direction of the movement of the sliding bracket 121, so as to move from the contact point with the guide surface to the fixed groove 123. When the sliding bracket 121 moves to the top of the mounting seat 15, one end of the moving shaft 142 is located in the fixed groove 123, fixing the sliding bracket 121, simplifying the control process of the electromagnet 141 by the control module, and eliminating the need for additional setting of a positioning component to detect the switching of the bearing seat 11 from the first state to the position. Through the cooperation of the guide surface and the fixed groove 123, the electromagnet 141 fixes the sliding bracket 121, simplifies the control of the electromagnet 141, and improves the operation efficiency of the reagent moving device 1.

[0057] When the bearing seat 11 needs to be switched from the first state to the second state, the control module can control the moving shaft 142 to retract, so that one end of the moving shaft 142 is separated from the fixed groove 123, and the sliding bracket 121 loses the fixing effect of the electromagnet 141 and moves away from the mounting seat 15 under the action of the elastic component 13.

[0058] In summary, through the setting of the elastic component 13 and the fixing component 14, the sliding bracket 121 can complete the switching between the first state and the second state without the driving of the motor, without the need for additional setting of the motor, reducing the device cost of the reagent moving device 1, reducing the occupied space of the reagent moving device 1, and improving the user experience of the reagent moving device 1.

[0059] Optionally, the reagent moving device 1 further comprises an identification component 16 fixed to the mounting seat 15 and spaced apart from the guide rail 122. The identification component 16 is used to be arranged adjacent to the bearing seat 11 when the bearing seat 11 is in the first state, and to identify the reagent information of the reagent bottle 2 on the bearing seat 11. The reagent information of the reagent bottle 2 can include the reagent type of the reagent in the reagent bottle 2.

[0060] Specifically, since the replacement of the reagent bottle 2 on the bearing seat 11 is manually performed by the user when the bearing seat 11 is in the second state, the identification component 16 is needed to identify the reagent information of the replaced reagent bottle 2, so as to avoid the situation that the reagent type of the reagent bottle 2 is not the reagent type required by the sample analyzer, thereby affecting the sample detection efficiency of the sample analyzer. Therefore, after the bearing seat 11 is switched to the first state, the identification component 16 identifies the reagent information of the reagent bottle 2 on the bearing seat 11, thereby improving the operation efficiency of the reagent moving device 1.

[0061] In an embodiment, a mechanical arm can be arranged to automatically replace the reagent bottle 2 on the carrier seat 11 when the carrier seat 11 is in the second state, reducing the manual participation rate, which is not limited in the application.

[0062] In another embodiment, a label area can be further arranged on the carrier seat 11, corresponding to the area where the reagent bottle 2 is loaded on the carrier seat 11, so that the user can replace the reagent bottle 2 according to the reagent information displayed on the label area, reducing the possibility of reagent replacement error, and further improving the sampling efficiency.

[0063] Optionally, when the carrier seat 11 is loaded with the first reagent bottle 21 and the second reagent bottle 22, the carrier seat 11 is provided with a first accommodating cavity 111 and a second accommodating cavity 112, the first reagent bottle 21 is placed in the first accommodating cavity 111, and the second reagent bottle 22 is placed in the second accommodating cavity 112.

[0064] The recognition assembly 16 includes a mounting plate 161, a first recognition member 162, and a second recognition member 163. The mounting plate 161 is vertically mounted on the mounting seat 15 and is arranged in a spaced manner with the guide slide rail 122, and the first recognition member 162 and the second recognition member 163 are arranged in a spaced manner on the side of the mounting plate 161 away from the guide slide rail 122.

[0065] When the carrier seat 11 is in the first state, the first recognition member 162 is arranged corresponding to the first accommodating cavity 111 for identifying the reagent type of the first reagent bottle 21, and the second recognition member 163 is arranged corresponding to the second accommodating cavity 112 for identifying the reagent type of the second reagent bottle 22.

[0066] Specifically, the bottle body of the first reagent bottle 21 and the second reagent bottle 22 can be provided with an identification card for storing reagent bottle information, and after the carrier seat 11 is switched to the first state, the first accommodating cavity 111 is adjacent to the first recognition member 162, the first recognition member 162 can identify the identification card on the first reagent bottle 21 to identify the reagent information of the first reagent bottle 21. At the same time, the second accommodating cavity 112 is adjacent to the second recognition member 163, and the second recognition member 163 identifies the identification card of the second reagent bottle 22 to identify the reagent information of the second reagent bottle 22. The accuracy of replacing the first reagent bottle 21 and the second reagent bottle 22 is improved, and the sampling efficiency of the reagent moving device 1 is improved.

[0067] In another embodiment, a plurality of accommodating cavities can be arranged on the carrier seat 11 for corresponding number of reagent bottles 2 of the device, and the recognition assembly 16 includes a corresponding number of recognition members for identifying the reagent information of the reagent bottles 2, which is not limited in the application.

[0068] Optionally, the elastic assembly 13 comprises a torsion spring 131, and the extending direction of the torsion spring 131 is perpendicular to the extending direction of the guide slide rail 122, so as to reduce the installation space of the torsion spring 131.

[0069] In the elastic assembly 13, one end of the torsion spring 131 is arranged on the mounting seat 15, and the other end of the torsion spring 131 is in abutment with the sliding bracket 121, and the sliding bracket 121 is used for compressing the torsion spring 131 when the bearing seat 11 is switched from the second state to the first state.

[0070] Specifically, in the process that the bearing seat 11 is switched from the second state to the first state, the sliding bracket 121 moves close to the mounting seat 15, pushes the movement of the abutment between the torsion spring 131 and the sliding bracket 121, and then twists the torsion spring 131. When the bearing seat 11 needs to be switched from the first state to the second state, the torsion spring 131 restores to the original shape, and provides an action force away from the mounting seat 15 to the sliding bracket 121.

[0071] In the elastic assembly 13, since the extending direction of the torsion spring 131 is perpendicular to the extending direction of the guide slide rail 122, when the bearing seat 11 is in the second state, the sliding bracket 121 can not be in abutment with the torsion spring 131, and in the process that the bearing seat 11 is switched from the second state to the first state, the sliding bracket 121 starts to be in abutment with one end of the torsion spring 131 after moving to the preset position, and then the torsion spring 131 is twisted.

[0072] In another embodiment, when the installation space on the mounting seat 15 is large, the elastic assembly 13 can also comprise a spring, and the extending direction of the spring is parallel to the extending direction of the guide slide rail 122. In the process that the sliding bracket 121 moves close to the mounting seat 15, the sliding bracket 121 compresses the spring, and the length of the spring is reduced. When the spring restores to the original length, the sliding bracket 121 is pushed to move away from the mounting seat 15.

[0073] It can be understood that the elastic assembly 13 can also comprise other elastic structures, and the application does not limit the movement of the sliding bracket 121.

[0074] Optionally, the reagent moving device 1 further comprises a sensor 17 and a sensing piece 18. The sensor 17 is arranged on the mounting seat 15, and the sensing piece 18 is arranged on the sliding bracket 121, and the sensing piece 18 is used for being arranged in the sensor 17 when the bearing seat 11 is in the first state.

[0075] Specifically, since the inductive piece 18 is arranged on the sliding bracket 121, that is, the inductive piece 18 moves with the sliding bracket 121, in the process of the sliding bracket 121 moving close to the mounting seat 15, the inductive piece 18 moves close to the sensor 17, and when the sliding bracket 121 moves to the mounting seat 15, the inductive piece 18 is located in the sensor 17, and the control module can respond to the switching of the bearing seat 11 from the first state to the position.

[0076] In this way, the sensor 17 and the inductive piece 18 are arranged, and the sliding bracket 121 can only include the fixed groove 123, so that in the process of the bearing seat 11 switching from the second state to the first state, the moving shaft 142 is in the retracted state, avoiding the moving shaft in the extended state from hindering the movement of the sliding bracket 121. After the bearing seat 11 switches to the first state, the sensor 17 responds to the switching of the bearing seat 11 from the first state to the position, and the control module (not shown in the figure) of the reagent moving device 1 controls the moving shaft 142 of the electromagnet 141 to extend, one end of the moving shaft 142 is located in the fixed groove 123, and the sliding bracket 121 is fixed, avoiding the elastic assembly 13 from pushing the sliding bracket 121, improving the safety and stability of the reagent moving device 1, and improving the control efficiency of the electromagnet 141.

[0077] After the sensor 17 responds to the switching of the bearing seat 11 from the first state to the position, the control module can control the detection device in the sample analyzer to start collecting the reagent in the reagent bottle 2 on the bearing seat 11, avoiding the risk of collision and bending of the sampling needle of the detection device caused by the sampling of the sampling needle when the bearing seat 11 does not switch to the position, and further improving the safety of the reagent moving device 1.

[0078] In an embodiment, the sensor 17 can be a position-coupling light coupling, and the inductive piece 18 can be a light-coupling blocking piece. After the bearing seat 11 switches to the first state to the position, the light-coupling blocking piece is arranged in the position-coupling light coupling, and the light beam emitted by the position-coupling light coupling is blocked, so that the position-coupling light coupling can respond to the switching of the bearing seat 11 from the first state to the position.

[0079] In another embodiment, the sensor 17 can also be arranged on the sliding bracket 121, and the inductive piece 18 is arranged on the mounting seat 15. When the sliding bracket 121 moves directly above the mounting seat 15, the inductive piece 18 can be located in the sensor 17, and the sensor 17 responds to the switching of the bearing seat 11 from the first state to the position.

[0080] In an embodiment, as shown in Figure 5 The sample analyzer further includes an automatic sampling device 4, and the automatic sampling device 4 is arranged at the front end of the sample analyzer. The reagent moving device 1 is arranged between the sample loading area and the sample unloading area of the automatic sampling device 4.

[0081] Optionally, a sampling needle (not shown in the figure) is included in the sample analyzer, which can be arranged at a distance from the mounting seat 15, and is used to collect reagents in the reagent bottle 2 placed in the carrier seat 11 in the first state, or to collect samples in the sample tube automatically fed by the automatic feeding device 4; and the detection device in the sample analyzer is used to receive the sample liquid after the sample collected by the sampling needle reacts with the reagents for sample detection.

[0082] Specifically, after the carrier seat 11 is switched from the first state to the position in response to the sensor 17, the control module can control the sampling needle to move above the carrier seat 11 to collect the reagents in the reagent bottle 2 loaded on the carrier seat 11, and then the detection device can use the sample liquid after the sample collected by the sampling needle reacts with the reagents for sample detection, thereby improving the operation efficiency of the sample analyzer.

[0083] By arranging the reagent assembly at the position of the automatic feeding device, the sampling needle can be reused for sample collection and reagent collection, especially for the arrangement of the dye reagent. Compared with the scheme that the dye reagent bottle is arranged on the side of the sample analyzer, the dye liquid is added to the reaction pool by using the sampling needle to collect and inject the dye liquid from the reagent bottle into the reaction pool, which can avoid the occurrence of dye liquid diffusion between the dye reagent bottle and the reaction pool due to long-term standing, thereby avoiding the need to discard the dye liquid contaminated by dye liquid diffusion, reducing the additional consumption of the dye liquid, and improving the utilization rate of the dye liquid.

[0084] Optionally, referring to Figure 3 , the reagent moving device 1 further includes a housing 19 arranged at a position corresponding to the sample inlet of the sample analyzer.

[0085] The housing 19 is arranged on the side of the sliding bracket 121 away from the mounting seat 15, and when the carrier seat 11 is switched to the first state, the housing 19 is located at the sample inlet to seal the sample inlet, thereby avoiding the sample inlet being open for a long time, preventing dust, water vapor and the like in the environment from entering the interior of the sample analyzer through the sample inlet, affecting the internal components of the sample analyzer, and polluting the samples in the interior of the sample analyzer, thereby improving the safety of the sample analyzer and the practicality of the reagent moving device 1.

[0086] In actual application, the user can push the sliding bracket 121 towards the mounting seat 15 through the housing 19, or after the sliding bracket 121 is pushed by the elastic assembly 13, the sliding bracket 121 is further pulled out through the housing 19, thereby facilitating the replacement of the first reagent bottle 21 and the second reagent bottle 22 on the carrier seat 11.

[0087] In an embodiment, referring to Figure 4 , Figure 4is a structural schematic diagram of a third embodiment of the reagent moving device of the application. The mounting seat 15 can also be provided with an emergency button 3, and the shell 19 can also be provided with a trigger 191, which is arranged on the same side of the shell 19 as the sliding bracket 121. When the carrier seat 11 is in the first state, the shell 19 is arranged in a spaced manner with the mounting seat 15, the trigger 191 is arranged adjacent to the emergency button 3, and the area of the shell 19 where the trigger 191 is located can be pushed. The user can push the corresponding area to push the trigger 191 to press the emergency button 3. After the emergency button 3 is triggered, the control module can control the sampling needle to move downward for sampling in response to the emergency sample or single sample requiring sampling. The trigger 191 has the function of opening the sampling of the sampling needle moving downward. When the emergency sample appears, the sample analyzer can respond in time and sample the emergency sample, thereby improving the practicability of the sample analyzer.

[0088] The sampling needle can be the sampling needle described above for collecting the reagent in the reagent bottle 2, thereby improving the utilization rate of the sampling needle and improving the operation efficiency of the sample analyzer.

[0089] In summary, by arranging the elastic assembly 13, the reagent moving device 1 provided by the embodiment of the application does not need to be provided with a motor to drive the movement of the sliding bracket 121 and the carrier seat 11, thereby reducing energy consumption, reducing the occupied space of the reagent moving device 1 in the sample analyzer, improving the adaptability of the reagent moving device 1 to the sample analyzer, improving the practicability of the reagent moving device 1, and improving the user experience of the reagent moving device 1.

[0090] In addition, the carrier seat 11 can load at least the first reagent bottle 21 and the second reagent bottle 22, thereby improving the sampling efficiency of the carrier seat 11 during the reagent bottle sampling process and further improving the operation efficiency of the reagent moving device 1. Further, by cooperating the first sliding rail 1221 and the second sliding rail 1222, the occupied space of the guide sliding rail 122 is further reduced while ensuring the movement distance of the sliding bracket 121, thereby reducing the occupied space of the reagent moving device 1 and improving the practicability of the reagent moving device 1.

[0091] The application also provides a sample analyzer. Please refer to Figure 5 , Figure 5 is a structural schematic diagram of an embodiment of the sample analyzer of the application. The sample analyzer A provided by the embodiment of the application comprises a reagent moving device 1 and a detection device (not shown in the figure). The detection device is arranged in the sample analyzer and is arranged in a spaced manner with the reagent moving device 1. The reagent moving device 1 is used to provide reagents for the detection device so that the detection device can detect the sample liquid after reacting with the reagents.
