Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a sample analysis system. Background Art

[0002] A sample analysis system (also known as a sample analyzer) is used to detect and analyze a substance to be measured. For example, the collected sample is analyzed to obtain various indicators for auxiliary diagnosis / treatment, or a quality control test is performed using a quality control product and a calibration test is performed using a calibration product before sample detection to ensure the accuracy and precision of the test. These substances to be measured are usually stored and scheduled in a container, and the temperature conditions for storing different types of substances to be measured may vary. When the sample analysis system detects some substances to be measured stored in a non-ambient temperature manner (such as low-temperature storage), the substance to be measured taken out from the storage location needs to be manually rewarmed or placed for natural rewarming before it can be sent into the sample analysis system for scheduling, dispensing, detection, etc., which brings inconvenience to the operation, and the controllability of the rewarming process is poor. Some substances to be measured will deteriorate after being placed at room temperature for a long time, affecting the accuracy of the detection results. Summary of the Invention

[0003] The present invention aims to at least solve the problem that the sample analysis system cannot rewarm the substance to be measured. To this end, the present invention provides a sample analysis system capable of online rewarming.

[0004] The sample analysis system according to an embodiment of the present invention includes a rewarming module, a detection module, and a scheduling module. The rewarming module is used to rewarm the substance to be measured. The rewarming module includes a housing member and a blower. An accommodation cavity is formed inside the housing member. The housing member is provided with an air inlet and an air outlet. The air inlet and the air outlet communicate with the accommodation cavity to form a rewarming air duct in the accommodation cavity. The blower is used to form an air flow that enters the rewarming air duct from the air inlet and flows out from the air outlet. The housing member is formed with a placement position for placing a container containing the substance to be measured, so that at least a part of the container placed at the placement position is located in the rewarming air duct. The substance to be measured includes a sample, a quality control product, or a calibration product. The detection module is used to detect the substance to be measured. The scheduling module is used to schedule the container of the rewarmed substance to be measured to the detection module for detection.

[0005] The sample analysis system according to the embodiments of the present invention has at least the following beneficial effects: When in use, a container containing a substance to be measured can be sent into a rewarming module in the sample analysis system and placed at a placement position of a placement member. A wind flow passing through the container is formed in a rewarming air duct by a blower, so that heat exchange and rewarming can be performed on the container and the substance to be measured contained in the container. The container of the substance to be measured after rewarming can be scheduled by a scheduling module to a detection module for detection. Thus, the substance to be measured that needs to be rewarmed can be taken out from a storage place and put into the sample analysis system for on-line rewarming and detection, which improves the applicability of the sample analysis system and the controllability of the rewarming operation. The wind flow can accelerate heat exchange of the container of the substance to be measured and the substance to be measured, thereby reducing the rewarming duration, effectively reducing the risk of deterioration of the substance to be measured, and ensuring the accuracy of detection.

[0045] Please refer to Figure 1 , an embodiment discloses a sample analysis system, including a sample component 11, a sample dispensing mechanism 12, a reagent component 13, a reagent dispensing mechanism 14, a mixing mechanism 15, a reaction component 16, a detection module 17, etc.

[0046] The sample component 11 is used to carry samples. In some examples, the sample component 11 may include a sample delivery module (SDM) and a front-end track; in other examples, the sample component 11 may also be a sample tray, which includes a plurality of sample positions for placing sample tubes, etc. The sample tray can rotate its disc structure to schedule the samples to corresponding positions, such as the position for the sample dispensing mechanism 12 to aspirate samples.

[0047] The sample dispensing mechanism 12 is used to aspirate samples and discharge them into the reaction cups to be loaded with samples. For example, the sample dispensing mechanism 12 may include a sample needle, and the sample needle can perform two-dimensional or three-dimensional movement in space through a two-dimensional or three-dimensional drive mechanism, so that the sample needle can move to aspirate the samples carried by the sample component 11, and move to the reaction cups to be loaded with samples and discharge the samples into the reaction cups.

[0048] The reagent component 13 is used to carry reagents. In one embodiment, the reagent component 13 may be a reagent tray, which is arranged in a disc-shaped structure and has a plurality of positions for carrying reagent containers. The reagent component 13 can rotate and drive the reagent containers carried by it to rotate, so as to rotate the reagent containers to specific positions, such as the position for the reagent dispensing mechanism 14 to aspirate reagents. The number of reagent components 13 can be one or more.

[0049] The reagent dispensing mechanism 14 is used to aspirate reagents and discharge them into the reaction cups to which reagents are to be added. In one embodiment, the reagent dispensing mechanism 14 may include a reagent needle, which moves spatially in two or three dimensions through a two-dimensional or three-dimensional drive mechanism, so that the reagent needle can move to aspirate the reagents carried by the reagent component 13, and move to the reaction cups to which reagents are to be added, and discharge the reagents into the reaction cups.

[0050] The mixing mechanism 15 is used to mix the reaction liquid that needs to be mixed in the reaction cups. The number of mixing mechanisms 15 can be one or more.

[0051] The reaction component 16 has at least one placement position for placing reaction cups and incubating the reaction liquid in the reaction cups. For example, the reaction component 16 can be a reaction disk, which is arranged in a disk-shaped structure and has one or more placement positions for placing reaction cups. The reaction disk can rotate and drive the reaction cups in its placement positions to rotate, for scheduling the reaction cups in the reaction disk and incubating the reaction liquid in the reaction cups.

[0052] The detection module 17 is used to perform photometric measurement on the reaction liquid after incubation to obtain the reaction data of the sample. For example, the detection module 17 detects the luminescence intensity of the reaction liquid to be measured, and calculates the concentration of the component to be measured in the sample through a calibration curve, etc. In one embodiment, the detection module 17 is separately arranged outside the reaction component 16.

[0053] In addition to analyzing and detecting samples, in order to ensure the accuracy of sample detection results, a sample analysis system needs to perform quality management through calibration products and / or quality control products. For example, as the sample analysis system is used and ages, the actual parameters of the detection module 17 of the sample analysis system will drift, and these drifts will affect the analysis accuracy. Therefore, calibration products can be used to calibrate the parameters. The calibration products are standard samples with determined and known relevant parameters. After the detection module 17 detects the calibration products, actual detection results can be obtained. Based on the actual detection results of the calibration products and the corresponding standard parameters, the detection module 17 can obtain a calibration curve, thereby performing equipment calibration. After calibrating the detection module 17, the calibrated detection module 17 can be used to analyze case samples. For another example, quality control products can also be used to determine whether the detection module 17 is in a normal working state. Similar quality control products are also standard samples with determined and known relevant parameters. When the detection module 17 detects the quality control products, actual detection results can be obtained. By comparing the actual detection results with the standard parameters, if the deviation of the actual detection results from the standard parameters is within the preset range, it is determined that the detection module 17 is in a normal working state; if the deviation of the actual detection results from the standard parameters is outside the preset range, it is determined that the detection module 17 is in an abnormal state. Therefore, in the embodiments of the present invention, the substances to be detected entering the sample analysis system for detection can be the collected samples, or the quality control products for quality control detection, or the calibration products for calibration detection. Among these substances to be detected, some need to be stored at low temperature and need to be rewarmed before detection. Taking quality control products (such as some dry powder quality control products and liquid quality control products with high and low concentrations) as an example, some quality control products need to be stored refrigerated at 2-8°C or frozen at -20°C. If the quality control products are left to warm up naturally, it takes a long rewarming time, and the quality control products will deteriorate after being placed at room temperature for a long time, thus affecting the test results.

[0054] The sample analysis system according to some embodiments of the present invention can perform online rewarming on the substances to be detected. Mainly, there is a rewarming module for rewarming the substances to be detected. After the substances to be detected are taken out from the storage location, they can be sent to the rewarming module for rewarming, and then they can participate in subsequent scheduling and detection, making the rewarming process controllable online, thereby improving the convenience of operation. The following is a detailed introduction with reference to the accompanying drawings of the specification:

[0055] The sample analysis system according to some embodiments of the present invention includes a rewarming module, a detection module, and a scheduling module.

[0056] Reference Figures 2 to 4, the rewarming module 200 includes a housing 210 and a blower 220. An accommodation cavity 201 is formed inside the housing 210. The housing 210 is provided with an air inlet 202 and an air outlet 203. The air inlet 202 and the air outlet 203 communicate with the accommodation cavity 201 to form a rewarming air duct in the accommodation cavity 201. The blower 220 is used to form an air flow that enters the rewarming air duct from the air inlet 202 and flows out from the air outlet 203. The housing 210 is formed with a placement position 214 for placing a container containing a substance to be measured, so that at least a part of the container placed at the placement position 214 is located in the rewarming air duct.

[0057] During use, the container containing the substance to be measured is sent into the rewarming module 200 and placed at the placement position 214 of the housing 210. The air flow in the rewarming air duct exchanges heat with the container, thereby reheating the substance to be measured inside the container. The detection module is used to detect the substance to be measured contained in the container, and the scheduling module is used to schedule the container containing the rewarmed substance to be measured to the detection module for detection. Thus, the rewarming module 200 in the sample analysis system is used to rewarm the substance to be measured, and the rewarmed substance to be measured can be scheduled to the detection module by the scheduling module for detection. The sample analysis system has an online rewarming function, improving the applicability of the sample analysis system and the controllability of the rewarming operation.

[0058] In the sample analysis system according to the embodiment of the present invention, the air flow formed in the rewarming air duct can accelerate the heat exchange between the container and the substance to be measured inside the container, thereby reducing the rewarming time, effectively reducing the risk of deterioration of the substance to be measured, and ensuring the accuracy of the detection. Increasing the wind speed and / or air volume can further improve the heat exchange efficiency to a certain extent, thereby further reducing the rewarming time.

[0059] In some embodiments, the sample analysis system may further include a storage module. The storage module includes a storage component and a refrigeration component. The storage component is provided with a storage cavity for placing a container containing a substance to be measured. The refrigeration component is used to provide cold to the storage cavity, thereby forming a low-temperature environment required for storing the substance to be measured in the storage cavity. For example, a refrigeration environment of 2-8°C or a refrigeration environment of about -20°C can be formed in the storage cavity through the refrigeration component. Alternatively, the storage component may be provided with a plurality of separated storage cavities, and the refrigeration component communicates with different storage cavities respectively, and different low-temperature environments with different temperature ranges can be formed in different storage cavities through the refrigeration component for separately storing substances to be measured with different storage requirements.

[0060] When testing is required, the container containing the substance to be measured can be taken out of the storage cavity and placed in the rewarming module 200 for rewarming. Among them, the storage module and the rewarming module 200 can be arranged within the scheduling range of the scheduling module, and the scheduling module can be used to schedule the container containing the substance to be measured from the storage module to the rewarming module 200 for rewarming.

[0061] Depending on the system, the scheduling module has different compositions.

[0062] When the sample analysis system is a single-machine detection system, where:

[0063] The scheduling module may include one or more manipulators within the single machine. The rewarming module 200 is arranged within the scheduling range of at least one manipulator. The manipulator takes out the container containing the substance to be tested after rewarming from the rewarming module 200 and schedules it to the detection module 17. In a sample analysis system equipped with a storage module, the storage module and the rewarming module 200 are arranged within the scheduling range of the manipulator. The manipulator takes out the container containing the substance to be tested from the storage module and schedules it to the rewarming module 200 for rewarming. The manipulator for scheduling between the rewarming module 200 and the detection module 17 and the manipulator for scheduling between the storage module and the rewarming module 200 may be the same manipulator or two different manipulators respectively;

[0064] Alternatively, the scheduling module may also include a combination of an in-machine track and one or more manipulators within the single machine. The rewarming module 200 is arranged along one side of the in-machine track within the scheduling range of at least one manipulator. The manipulator takes out the container containing the substance to be tested after rewarming from the rewarming module 200 and schedules it to the in-machine track, and is scheduled to the detection module 17 by the in-machine track; In a sample analysis system equipped with a storage module, the storage module and the rewarming module 200 may be arranged within the scheduling ranges of different manipulators. One manipulator takes out the container containing the substance to be tested from the storage module and schedules it to the in-machine track, is transported by the in-machine track to the scheduling range of another manipulator, and is scheduled from the in-machine track to the rewarming module 200 for rewarming by this manipulator.

[0065] When the sample analysis system is a detection pipeline system, where:

[0066] The scheduling module may include one or more manipulators within the system. The rewarming module 200 is arranged within the scheduling range of at least one manipulator. The manipulator takes out the container containing the substance to be tested after rewarming from the rewarming module 200 and schedules it to the detection module 17. In a sample analysis system equipped with a storage module, the storage module and the rewarming module 200 are arranged within the scheduling range of the same manipulator. The manipulator takes out the container containing the substance to be tested from the storage module and schedules it to the rewarming module 200 for rewarming; The manipulator for scheduling between the rewarming module 200 and the detection module 17 and the manipulator for scheduling between the storage module and the rewarming module 200 may be the same manipulator or two different manipulators respectively;

[0067] Alternatively, the scheduling module may also include a combination of an orbital module within the pipeline system and one or more robotic arms within the system. The rewarming module 200 is disposed on one side of the orbital module within the pipeline system within the scheduling range of at least one robotic arm. The robotic arm takes out the container containing the substance to be tested after rewarming from the rewarming module 200 and schedules it to the orbital module, and the orbital module schedules it to the detection module 17. In a sample analysis system provided with a storage module, the storage module and the rewarming module 200 may be disposed within the scheduling ranges of different robotic arms. One robotic arm takes out the container containing the substance to be tested from the storage module and schedules it to the orbital module within the pipeline system, and the orbital module transports it to the scheduling range of another robotic arm, and this robotic arm schedules it from the orbital module to the rewarming module 200 for rewarming.

[0068] In some embodiments, the sample analysis system is a detection pipeline system, and the sample analysis system further includes a sample input module. The sample input module is at least used for the user to input a container containing the substance to be tested. The scheduling module includes an orbital module, and the orbital module is connected to the sample input module, the storage module, the rewarming module 200 and the detection module 17. In some embodiments, the orbital module includes a main rail and at least one front rail connected to the main rail. The main rail and the front rail have at least two tracks with opposite transportation directions. The tracks can transport single tube seats, and the single tube seats are used to carry a single container containing the substance to be tested. The sample input module is connected to the main rail, and the storage module, the rewarming module 200 and the detection module 17 are connected to the same or different front rails.

[0069] The orbital module transports the container containing the substance to be tested among the sample input module, the storage module, the rewarming module 200 and the detection module. For example, the orbital module transports the container containing the substance to be tested stored in the storage module to the rewarming module 200 to perform the rewarming operation, transports the container to the detection module 17 to perform the detection operation after the rewarming operation, and transports the container to the storage module for storage again after the detection operation. In addition, the orbital module can also transport the container containing the substance to be tested in the sample input module to the storage module for storage. It can be understood that some substances to be tested are usually taken out in batches for testing, and the consistency of the rewarming temperature of the substances to be tested within the same batch will affect the accuracy of the test results. For example, the inconsistent rewarming temperatures among the quality control products (or calibration products) within the same batch will affect the accuracy of the quality control test results. In some embodiments, the number of placement positions 214 is at least two, which can be used to place at least two containers containing the substances to be tested, so as to perform synchronous rewarming to improve the consistency of the rewarming temperature of the substances to be tested. Specifically, the number of placement positions 214 can be two, three or more, and is used to place multiple containers containing the substances to be tested. Thus, during the rewarming process, the air flow in the rewarming air duct can flow through multiple containers containing the substances to be tested, and the substances to be tested in multiple containers can be rewarmed simultaneously, effectively improving the consistency of the rewarming temperature of the substances to be tested within the batch.

[0070] Reference Figure 3 and Figure 4 In some embodiments, along the extending direction of the rewarming air duct (such as the left - right direction in the figure), at least some of the placement positions 214 are staggered, so that the containers placed in the placement positions 214 are also staggered. This can effectively prevent the containers from blocking each other along the extending direction of the rewarming air duct, facilitating the air flow in the rewarming air duct to pass through each container, and is beneficial for the temperature of the substance to be measured to quickly reach the rewarming temperature.

[0071] Specifically, the placement positions 214 can be staggered in various ways. For example, there may be no specific distribution pattern between the placement positions 214, as long as there are gaps for the air flow to pass between adjacent placement positions 214. Or, some or all of the placement positions 214 can be arranged in order. For example, Figures 2 to 4 Taking the shown manner as an example, the rewarming air duct extends along the left - right direction as shown. Some or all of the placement positions 214 can be distributed in at least two columns. The arrangement direction of the placement positions 214 in each column is perpendicular to the extending direction of the rewarming air duct, that is, the placement positions 214 in each column are spaced apart along the front - back direction. The columns are spaced apart along the left - right direction. There are gaps between the placement positions 214 in the same column, and the placement positions 214 in adjacent columns are staggered in the left - right direction. For example, in any two adjacent placement positions 214 in the left - right adjacent columns, the placement positions 214 in the right - hand column are opposite to the gaps between two adjacent placement positions 214 in the left - hand column in the left - right direction. Only a part of the placement positions 214 can be arranged in the above order, and the remaining placement positions 214 can have no specific distribution order; or, all of the placement positions 214 can be arranged in the above order.

[0072] Reference Figure 3 and Figure 4 In some embodiments, the accommodating member 210 includes a side wall 211, a bottom wall 212, and a placement member 213. The side wall 211 protrudes from the surface of the bottom wall 212 on one side of the bottom wall 212. The side wall 211 and the bottom wall 212 enclose an accommodating cavity 201. The placement member 213 is disposed in the accommodating cavity 201, and placement positions 214 are provided on the placement member 213. Thus, the container containing the substance to be measured can be placed in the placement positions 214 in the accommodating cavity 201.

[0073] Specifically, the placement member 213 may be in the shape of a plate, and the placement position 214 on the placement member 213 is a through slot that passes through the placement member 213, and the container containing the substance to be tested may pass through the through slot so that the bottom of the container abuts against the bottom wall 212, thereby placing the container. Alternatively, the placement member 213 may also be other structures capable of placing a container, for example, the placement member 213 may include at least one pair of clips, which are connected to the side wall 211 or the bottom wall 212 of the accommodating member 210, and the two paired clips fix at least one container in the accommodating cavity 201 in a clamping manner.

[0074] refer to Figure 3 and Figure 4 In some embodiments, a ventilation space 205 at least partially overlaps with the rewarming air duct is provided between the placement member 213 and the bottom wall 212, and at least a portion of the container placed at the placement position 214 is located in the ventilation space 205. Therefore, the airflow formed by the fan 220 in the rewarming air duct can at least partially pass through the ventilation space 205, so that at least the portion of the container located in the ventilation space 205 can be heat exchanged and rewarmed.

[0075] In the scheme where the placement piece 213 is a plate-like structure, the distance of the placement piece 213 relative to the bottom wall 212 may be smaller than the distance between the end of the side wall 211 facing away from the bottom wall 212 (for example, the upper end in the figure) and the bottom wall 212, that is, the upper end of the side wall 211 is higher than the placement piece 213, so that the ventilation space 205 between the placement piece 213 and the bottom wall 212 forms a ventilation space 205 that partially overlaps with the rewarming air duct, and the wind flow formed by the fan 220 may partially pass through the ventilation space 205; or, the placement piece 213 is flush with one end of the side wall 211 (for example, the upper end in the figure), so that the ventilation space 205 between the placement piece 213 and the bottom wall 212 and the rewarming air duct completely overlap. The plate-shaped placement piece 213 can be enclosed between the side walls 211 on the opposite side of the bottom wall 212, thereby guiding the wind flow together with the side walls 211 and the bottom wall 212, and can effectively guide the wind flow entering from the air inlet 202 to flow out from the air outlet 203, reducing or avoiding the wind flow from other positions. Dissipation, thereby improving heat exchange efficiency.

[0076] refer to Figures 4 to 6 In some embodiments, the bottom wall 212 may be provided with a positioning structure corresponding to the placement position 214, so that the container containing the substance to be tested placed in the placement position 214 can be positioned on the bottom wall 212 through the positioning structure, reducing or avoiding the shaking of the container, so that the scheduling module can accurately obtain the container and schedule it to the next process.

[0077] Among them, reference Figure 5 and Figure 6 The positioning structure may include a positioning protrusion 215 protruding from the bottom wall 212, and the positioning protrusion 215 is arranged on at least one side of the circumference of the projection B of the placement position 214 on the bottom wall 212. For ease of understanding, Figure 6The projection B of one of the placement positions 214 is schematically shown by a dashed line, and the projections of the other placement positions 214 are not shown. For example, the positioning protrusion 215 may be provided on one side in the circumferential direction of the projection B of the placement position 214 on the bottom wall 212; alternatively, the positioning protrusion 215 is provided on two opposite sides in the circumferential direction of the projection B of the placement position 214 on the bottom wall 212; alternatively, the positioning protrusion 215 may be provided at multiple locations (such as three, four, or more) on the circumferential side of the projection B of the placement position 214 on the bottom wall 212. Therefore, when the container containing the substance to be measured is placed at the placement position 214, the positioning protrusion 215 can be located on the outer side in the circumferential direction of the container, so that the positioning protrusion 215 abuts against the side wall of the container, thereby positioning the container on the bottom wall 212. It can be understood that when the container containing the substance to be measured is placed at the placement position 214, the lower part of the container faces the bottom wall 212 and the upper part is away from the bottom wall 212. The middle or upper part of the container is positioned by the placement position 214, and the lower part of the container can be positioned on the bottom wall 212 by the positioning protrusion 215.

[0078] In some embodiments, the positioning protrusion 215 may be provided on one side in the circumferential direction of the projection B of the placement position 214 on the bottom wall 212, so as to be adapted to abut against one side of the side wall of the container containing the substance to be measured, and position the container on the bottom wall 212 from one direction around the container, so as to facilitate the scheduling module to accurately obtain the container. In the solution where the placement member 213 is provided with at least two placement positions 214, the positioning protrusions 215 corresponding to the respective placement positions 214 can make the upper parts of the respective containers face the same direction, so as to facilitate the scheduling module to accurately obtain the container. In addition, the side wall of the container can be exposed in the rewarming air duct in the directions where there are no positioning protrusions 215, so as to facilitate heat exchange by the air flow.

[0079] In some other embodiments, the positioning protrusion 215 may be provided on two opposite sides in the circumferential direction of the projection B of the placement position 214 on the bottom wall 212, so as to be adapted to abut against two opposite sides of the side wall of the container containing the substance to be measured, and position the container on the bottom wall 212 from two opposite directions around the lower part of the container, improving the stability of container positioning. There may be a gap between the two positioning protrusions 215 for the air flow to pass through, so as to form a convection, so that the part of the lower part of the container blocked also has air flow passing through, avoiding the formation of an air flow dead angle between the positioning protrusions 215.

[0080] In some other embodiments, the positioning protrusion 215 may be provided at multiple locations (such as three, four, or more) on the circumferential side of the projection B of the placement position 214 on the bottom wall 212. The positioning protrusions 215 may be distributed in a circular pattern, so as to be adapted to abut against multiple positions on the circumferential side of the side wall of the container containing the substance to be measured, and position the container on the bottom wall 212 from multiple directions around the lower part of the container. There may be a gap between the respective positioning protrusions 215 for the air flow to pass through, avoiding the formation of an air flow dead angle.

[0081] It can be understood that the air flow enters the reheating air duct from the air inlet 202 and flows out from the air outlet 203. The container has a windward side facing the air flow and a leeward side opposite to the windward side. For example Figure 4 As shown, taking the air inlet 202 being provided on the left side of the accommodating member 210 and the air outlet 203 being provided on the right side of the accommodating member 210 as an example, the air enters the reheating air duct from the air inlet 202 and flows out from the air outlet 203 to form an air flow from left to right. The side of the container facing left is the windward side, and the side facing right is the leeward side. When the air flow passes through the container, it first contacts the windward side of the container, and then a part of it bypasses the container to reach the leeward side of the container. Therefore, the heat exchange and reheating efficiency of the windward side of the container is better than that of the leeward side.

[0082] Reference Figure 5 and Figure 6 , in some embodiments, the positioning protrusion 215 is at least located on the side of the projection B of the placement position 214 on the bottom wall 212 facing the air outlet 203, so as to abut against the side of the container containing the substance to be measured facing the air outlet 203. Therefore, when the air flow passes through the container, the positioning protrusion 215 can be located on the leeward side of the container to abut against the lower part of the container, reducing the shielding of the windward side of the container to ensure that the windward side has a larger heat exchange area. Among them, the positioning protrusion 215 may include at least two protrusion parts 216 circumferentially spaced along the projection B of the placement position 214 on the bottom wall 212. There is a gap 216a between two adjacent protrusion parts 216, allowing the air flow to pass through and reducing the obstruction of the air flow by the positioning protrusion 215.

[0083] Reference Figure 4 、 Figure 7 and Figure 8 , in some embodiments of the present invention, the accommodating member 210 further includes at least two air guiding members 217. The air guiding members 217 are located in the ventilation space 205 and are spaced along a direction perpendicular to the extending direction of the reheating air duct (such as the front-back direction in the figure). The air guiding members 217 are connected to the bottom wall 212 and / or the placement member 213 to fix the position of the air guiding members 217. Specifically, between the bottom wall 212 and the placement member 213, the air guiding members 217 have a set height in the up-down direction, where: one end of the air guiding member 217 facing the bottom wall 212 (such as the lower end in the figure) can be connected to the bottom wall 212 to fix the position of the air guiding member 217, and one end of the air guiding member 217 facing the placement member 213 (such as the upper end in the figure) can be in contact with the placement member 213 or have a gap; or, the upper end of the air guiding member 217 can be connected to the placement member 213, and the lower end of the air guiding member 217 can be in contact with or have a gap with the bottom wall 212; or, the lower end of the air guiding member 217 is connected to the bottom wall 212 and the upper end of the air guiding member 217 is connected to the placement member 213.

[0084] Along the extension direction of the rewarming air duct (the left - right direction in the figure), the air guiding member 217 can extend from the air inlet 202 to the air outlet 203. That is to say, along the left - right direction, the length of the air guiding member 217 extends to the entire length of the ventilation space 205; or, along the extension direction of the rewarming air duct (the left - right direction in the figure), the extension length of the air guiding member 217 can be less than the extension length of the ventilation space 205. That is to say, along the left - right direction, the length of the air guiding member 217 does not extend to the entire length of the ventilation space 205, and there are still some areas in the ventilation space 205 where no air guiding member 217 is provided, which can leave an installation space for setting other structures, such as a fan.

[0085] Reference Figure 7 and Figure 8 , an air guiding channel 206 is formed between adjacent air guiding members 217. At least part of the container placed in the placement position 214 is located in the air guiding channel 206. When the air enters the rewarming air duct from the air inlet 202, it can flow through the air guiding channel 206 towards the air outlet 203. The air guiding member 217 plays a role in guiding the air and ensures that the air flow can pass through the part of the container located in the air guiding channel 206, improving the rewarming efficiency of the substance to be measured in the container.

[0086] Specifically, referring to Figure 7 and Figure 8 , the air guiding channel 206 can include a receiving groove 207 corresponding to the placement position 214 and a guiding groove 208 communicating with the receiving groove 207. At least part of the container placed in the placement position 214 is located in the receiving groove 207, and the air flow can pass through the guiding groove 208 and the receiving groove 207, thereby exchanging heat with the container and the substance to be measured inside the container. Along the direction perpendicular to the extension direction of the rewarming air duct (the front - back direction in the figure), there is a gap between the groove wall of the receiving groove 207 and the container for the air flow to pass through. A communication port 209 is formed at the connection of the guiding groove 208 and the receiving groove 207. Along the front - back direction, the width W1 of the communication port 209 is less than the maximum width W2 of the receiving groove 207. Therefore, the receiving groove 207 forms a closed - mouth structure with the width decreasing towards the direction of the communication port 209. The side wall of the container placed in the receiving groove 207 can abut against this closed - mouth structure, and the container containing the substance to be measured can be positioned between the placing member 213 and the bottom wall 212.

[0087] Reference Figures 5 to 8 , in some embodiments, the positioning structure on the bottom wall 212 and the air guiding member 217 can be selectively provided in the rewarming module 200. In other embodiments, the rewarming module 200 can also have the above - mentioned positioning structure on the bottom wall 212, and at the same time, the above - mentioned air guiding member 217 can also be provided between the bottom wall 212 and the placing member 213, as long as the position is adjusted to avoid interference between the positioning structure and the air guiding member 217. For example, the air guiding member 217 and the positioning structure can be respectively provided corresponding to different regions of the bottom wall 212, so as toFigure 9 and Figure 10 Taking the embodiment shown as an example, along the left - right direction, the bottom wall 212 has a left - hand region and a right - hand region. The positioning structure is provided in the right - hand region of the bottom wall 212, and the air - guiding member 217 is arranged in the left - hand region, thus located on the left side of the positioning structure. Therefore, the air - guiding channel 206 formed by the positioning structure and the air - guiding member 217 can respectively correspond to the placement positions 214 in different regions. During use, select the placement position 214 corresponding to the air - guiding channel 206 or corresponding to the positioning structure to place the container containing the substance to be measured, or containers containing the substance to be measured can also be placed at both the placement position 214 corresponding to the air - guiding channel 206 and the placement position 214 corresponding to the positioning structure. The air - guiding member 217 forms the air - guiding channel 206 on the left side of the positioning structure, playing the role of guiding air.

[0088] In the sample analysis system, the container rewarmed by the rewarming module 200 can be transferred into the next process through the scheduling module. Since some substances to be measured need to be refrigerated or frozen and stored in a low - temperature environment, after the substance to be measured is taken out of the low - temperature environment, the temperature difference between the container containing the substance to be measured and the environment causes condensation water to form on the surface of the container. When the scheduling module transfers the container after rewarming, the condensed water on the surface of the container is extremely likely to drip into the open container and contaminate the substance to be measured therein, thereby affecting the accuracy of the detection and analysis results. In the sample analysis system of some embodiments of the present invention, referring to Figure 4 , the rewarming module 200 may further include a water - absorbing member 218. The water - absorbing member 218 can be arranged on the placing member 213. The water - absorbing member 218 is used to absorb the moisture formed on the surface of the container containing the substance to be measured placed at the placement position 214, which can reduce or remove the moisture on the surface of the container containing the substance to be measured and reduce the probability of the substance to be measured being contaminated by the condensed water. Among them, the water - absorbing member 218 can be made of materials with water - absorbing ability such as absorbent cotton and absorbent cloth. The water - absorbing member 218 is arranged on the placing member 213 at least at the position where the placement position 214 is located. When the container containing the substance to be measured is placed at the placement position 214, the water - absorbing member 218 is adapted to abut against the container containing the substance to be measured.

[0089] The water - absorbing member 218 can cover the side of the placing member 213 facing away from the bottom wall 212 (the upper side in the figure), and there are gaps or through - holes at the position corresponding to the placement position 214 for the container containing the substance to be measured to pass through. When the container is placed at the placement position 214, the edges of the gaps or through - holes can abut against the outer surface of the container. Therefore, during the process of the container being placed into or taken out from the placement position 214, and when the container is placed at the placement position 214, the water - absorbing member 218 can absorb the moisture formed on the outer surface of the container through the edges of the gaps or through - holes.

[0090] Alternatively, the water absorbent member 218 may also be provided on at least one side in the circumferential direction of the placement position 214. The water absorbent member 218 can be placed or adhered to the surface of the placement member 213 facing away from the bottom wall 212 (such as the upper surface in the figure). When the container of the substance to be tested is placed in the placement position 214, the edge of the water absorbent member 218 can abut against the outer surface of the container. Therefore, during the process of the container being inserted into or removed from the placement position 214, and when the container is placed in the placement position 214, the water absorbent member 218 can absorb the moisture on the outer surface of the container through the edge. When the air flow passes through the rewarming air duct, generally less moisture is formed on the surface of the container facing the air inlet 202 side, and more moisture is formed on the surface facing the air outlet 203 side. Therefore, the water absorbent member 218 can also be provided on the side of the placement position 214 facing the air outlet 203. When the container of the substance to be tested is placed in the placement position 214, the edge of the water absorbent member 218 can abut against the outer surface of the container facing the air outlet 203 side. Therefore, during the process of the container being inserted into or removed from the placement position 214, and when the container is placed in the placement position 214, the water absorbent member 218 can absorb the moisture on the outer surface of the container facing the air outlet 203 side through the edge.

[0091] Reference Figures 2 to 4 , an opening 204 may also be provided on a side of the accommodating member 210 different from the air inlet 202 and the air outlet 203. The container containing the substance to be tested can enter and exit the placement position 214 of the placement member 213 through the opening 204. In some embodiments, the side wall 211 of the accommodating member 210 includes two first side plates arranged at intervals facing each other, and two second side plates arranged at intervals facing each other between the two first side plates. The two first side plates, the two second side plates and the bottom wall 212 enclose an accommodating cavity 201 with an opening 204 on one side, which can allow the container of the substance to be tested to enter and exit the accommodating cavity 201. One of the two first side plates is provided with the air inlet 202, and the other is provided with the air outlet 203; alternatively, one of the two second side plates is provided with the air inlet 202, and the other is provided with the air outlet 203.

[0092] In other embodiments, the two side plates of the accommodating member 210 can also be omitted. For example, the side wall 211 of the accommodating member 210 may include two first side plates arranged at intervals facing each other in the front-rear direction. The two first side plates and the bottom wall 212 enclose an accommodating cavity 201 with openings at the left and right sides and the upper end. Among them, the opening at the upper end forms an opening 204 at the upper end of the side wall 211 for the container containing the substance to be tested to enter and exit the accommodating cavity 201, and the openings at the left and right sides can respectively form the air inlet 202 and the air outlet 203 of the accommodating member 210, thereby forming a rewarming air duct directly communicating with the left and right sides. The cross-sectional areas of the air inlet 202 and the air outlet 203 in the direction perpendicular to the bottom wall 212 and the first side plates (such as the front-rear direction in the figure) are equal to the cross-sectional area of the accommodating cavity 201, and are larger than the cross-sectional areas of the air inlet 202 and the air outlet 203 provided on the second side plate in the above embodiment, which is beneficial to increasing the air volume to improve the rewarming efficiency.

[0093] In some embodiments, reference Figure 3 The rewarming module 200 may further include a cover 219 covering the opening 204, and the cover 219 is movably connected to the side wall 211. For example, one side of the cover 219 may be connected to an end of the side wall 211 facing away from the bottom wall 212 (such as the upper end in the figure) by hinged or pivoted connection, and the cover 219 may rotate around the connection to open or close the opening 204; or, one of the cover 219 and the side wall 211 is connected to a slide rail, and the other is connected to a slider, and the cover 219 and the side wall 211 are slidably connected via the slider and the slide rail, and the cover 219 may slide relative to the side wall 211 to open or close the opening 204. When the rewarming module 200 is working, the cover 219 can close the opening 204. Compared with the solution without the cover 219, the cover 219 can form a relatively closed rewarming air duct after closing the opening 204, so that all or most of the air entering the rewarming air duct from the air inlet 202 is discharged from the air outlet 203, reducing air dissipation. After the rewarming of the substance to be tested is completed, the opening 204 can be opened and the container of the substance to be tested can be transferred out of the rewarming module 200 through the scheduling module.

[0094] In the sample analysis system of the above embodiment, the fan 220 can be a device for unified air supply in the sample analysis system, connected to the air inlet 202 through a pipeline; or, the fan 220 can also be a device for unified exhaust in the sample analysis system, connected to the air outlet 203 through a pipeline; or, the fan 220 can also be a commonly used independently detachable fan 220, and a commonly used normal temperature fan 220 or a hot air fan 220 can be selected, or a commonly used fan 220 with a normal temperature and hot air mode can be selected. A variety of settings can be used, for example, refer to Figures 2 to 4 :

[0095] In some embodiments, the fan 220 may be located in the rewarming air duct, or located outside the air outlet 203 in the sample analysis system. The fan 220 may be an exhaust fan 220, which may exhaust air from the air outlet 203 to the outside of the rewarming air duct when in operation. As the air inside the rewarming air duct is exhausted to the outside from the air outlet 203, under the effect of the negative pressure formed inside the rewarming air duct, the air outside the accommodation member 210 may enter the rewarming air duct from the air inlet 202, thereby forming a wind flow in the rewarming air duct that enters from the air inlet 202 and is discharged from the air outlet 203.

[0096] Alternatively, in some embodiments, the blower 220 is located inside the rewarming air duct or outside the air inlet 202 in the sample analysis system. The blower 220 can be an air supply blower 220, which can intake air from the air inlet 202 into the interior of the rewarming air duct during operation. As air is sent into the interior of the rewarming air duct from the air inlet 202, the gas inside the rewarming air duct can be discharged from the air outlet 203 as the air pressure increases, thereby forming an air current that enters from the air inlet 202 and exits from the air outlet 203 inside the rewarming air duct.

[0097] Alternatively, in some embodiments, the number of blowers 220 is at least two. At least one blower 220 is located inside the rewarming air duct or outside the air outlet 203 in the sample analysis system to exhaust air from the air outlet 203 to the outside of the rewarming air duct, and at least one blower 220 is located inside the rewarming air duct or outside the air inlet 202 in the sample analysis system to intake air from the air inlet 202 into the interior of the rewarming air duct. Thus, under the action of the blowers 220 on both sides, air is sent into the interior of the rewarming air duct from the air inlet 202 while the air inside the rewarming air duct is discharged towards the air outlet 203. Compared with the method of arranging only one blower 220 on one side, the air volume and / or air speed can be further increased, thereby improving the rewarming efficiency.

[0098] Reference Figure 2 、 Figure 11 and Figure 12, in some embodiments, the blower 220 includes a mounting bracket 221 and a fan 222. The mounting bracket 221 is located outside the reheating air duct and is connected to the accommodating member 210. A wind guiding cavity 223 is formed inside the mounting bracket 221. The wind guiding cavity 223 has a first air guiding opening 224 formed on the side of the mounting bracket 221 facing away from the accommodating member 210, and a second air guiding opening 225 formed on the side of the mounting bracket 221 facing the accommodating member 210. The fan 222 is located in the wind guiding cavity 223 or outside the first air guiding opening 224 facing away from the wind guiding cavity 223, and the second air guiding opening 225 communicates with the reheating air duct. It can be understood that the fan 222 generally has a rotating shaft for rotational connection and fan blades provided on the circumference of the rotating shaft, and drives the air to flow by rotation to generate an air current. The fan 222 can be rotationally connected to the mounting bracket 221 through the rotating shaft. For example, the mounting bracket 221 is provided with a connecting portion in the wind guiding cavity 223, the fan 222 is located in the wind guiding cavity 223 and is rotationally connected to the connecting portion through the rotating shaft, or the mounting bracket 221 is provided with a connecting portion outside the first air guiding opening 224 facing away from the wind guiding cavity 223, and the fan 222 is located outside the first air guiding opening 224 facing away from the wind guiding cavity 223 and is rotationally connected to the connecting portion through the rotating shaft to realize the installation of the fan 222. It can be understood that a blower 220 with a larger power generally has a fan 222 with a larger radial dimension, which can generate a higher wind speed and / or a larger air volume. In the embodiments of the present invention, the power of the blower 220 can be reasonably configured according to the requirements of the air volume and / or wind speed, or according to the size of the installation space.

[0099] Among them, with reference to Figure 11 and Figure 12 :

[0100] In the solution where the blower 220 is located outside the air outlet 203 of the sample analysis system, the second air guiding opening 225 of the mounting bracket 221 is docked with the air outlet 203. The air in the reheating air duct is discharged from the air outlet 203 to the second air guiding opening 225 and flows into the wind guiding cavity 223, and after being converged by the wind guiding cavity 223, it is exhausted outside the wind guiding cavity 223 through the first air guiding opening 224 by the fan 222. In some embodiments, the area of the first air guiding opening 224 is larger than the area of the air outlet 203, which is applicable to a larger-sized fan 222, so as to be applicable to a blower 220 with a larger power, and can provide a higher exhaust wind speed and / or a larger air volume, which helps to improve the reheating efficiency.

[0101] In the solution where the fan 220 is located outside the air inlet 202 in the sample analysis system, the second air guide port 225 of the mounting bracket 221 is docked with the air inlet 202. The air flow formed by the fan 222 can enter the air guide cavity 223 through the first air guide port 224, and after converging in the air guide cavity 223, it enters the reheating air duct from the second air guide port 225. In some embodiments, the area of the first air guide port 224 is larger than that of the air inlet 202, which can be applicable to larger-sized fans 222, so as to be applicable to higher-power fans 220, and can provide higher air supply wind speed and / or larger air volume, which helps to improve the reheating efficiency.

[0102] Reference Figure 11 and Figure 12 , in some embodiments, in the direction extending from the first air guide port 224 to the second air guide port 225, the longitudinal cross-sectional area of at least part of the air guide cavity 223 gradually decreases, so that the area of the second air guide port 225 is smaller than that of the first air guide port 224, and the inner wall of the air guide cavity 223 forms a structure that contracts towards the second air guide port 225. Therefore, a fan 222 with a larger size than the second air guide port 225 can be arranged at a position in the air guide cavity 223 closer to the first air guide port 224 relative to the second air guide port 225, or outside the first air guide port 224 relative to the air guide cavity 223. The external dimension of the accommodating member 210 can also be reasonably reduced to save space occupation. The smaller accommodating member 210 makes the areas of the air inlet 202 and the air outlet 203 smaller. The second air guide port 225 with a smaller area is docked with the air inlet 202 or the air outlet 203, and the first air guide port 224 with a larger area can be applicable to larger-sized fans 222. Therefore, when the size of the accommodating member 210 is reduced, it is not necessary to reduce the size of the fan 222, so that sufficient air volume can be provided into the reheating air duct for heat exchange and reheating.

[0103] In the fan 220 communicated with the air inlet 202 through the second air guide port 225, the air flow sent out by the fan 222 can be guided towards the second air guide port 225 through the air guide cavity 223, and then enters the reheating air duct from the air inlet 202. Most of the air flow generated when the fan 222 intakes air converges towards the second air guide port 225, and the contracting structure of the inner wall of the air guide cavity 223 can also accelerate the air flow, which helps to improve the heat exchange efficiency of the air flow in the reheating air duct. In the fan 220 communicated with the air outlet 203 through the second air guide port 225, the contracting structure of the inner wall of the air guide cavity 223 can be applicable to the reheating air duct with a smaller air outlet 203. The second air guide port 225 is docked with the air outlet 203. When the fan 222 exhausts air, the air inside the reheating air duct enters the air guide cavity 223 through the air outlet 203 and the second air guide port 225, and then can be discharged from the first air guide port 224 through the fan 222, which can reduce other air mixed into the air guide cavity 223, effectively improve the exhaust efficiency, and help to improve the heat exchange efficiency of the air flow in the reheating air duct.

[0104] Reference Figure 4 、 Figure 11 and Figure 12 , in some embodiments, a wind guiding surface 228 may be formed on the inner wall of the wind guiding cavity 223. In the direction extending from the first air guiding port 224 to the second air guiding port 225, the wind guiding surface 228 is inclined towards the rewarming air duct. Only one of the above-mentioned wind guiding surfaces 228 may be provided on the inner wall of the wind guiding cavity 223, or the above-mentioned wind guiding surfaces 228 may also be provided on two or more sides in the radial direction of the wind guiding cavity 223. Thus, the longitudinal cross-sectional area of the part of the wind guiding cavity 223 having the wind guiding surface 228 gradually decreases, forming a structure that contracts towards the second air guiding port 225.

[0105] In the above embodiments, in the direction extending from the first air guiding port 224 to the second air guiding port 225, the longitudinal cross-sectional area of the wind guiding cavity 223 gradually decreases from the first air guiding port 224 to the second air guiding port 225, forming a structure that contracts towards the second air guiding port 225. In some other embodiments, reference Figure 12 , the wind guiding cavity 223 may include a contraction section 226 and a connection section 227. In the direction extending from the first air guiding port 224 to the second air guiding port 225, the longitudinal cross-sectional area of the contraction section 226 gradually decreases from the first air guiding port 224 to the second air guiding port 225, forming a structure that contracts towards the second air guiding port 225; the connection section 227 is located between the first air guiding port 224 and one end of the contraction section 226 facing away from the second air guiding port 225, and the other end of the contraction section 226 extends to the second air guiding port 225; or, the connection section 227 is located between the second air guiding port 225 and one end of the contraction section 226 facing away from the first air guiding port 224, and the other end of the contraction section 226 extends to the first air guiding port 224; or, connection sections 227 are distributed between both ends of the contraction section 226 and the first air guiding port 224 and the second air guiding port 225. Among them, the connection section 227 may be a structure with a constant longitudinal cross-sectional area in the direction extending from the first air guiding port 224 to the second air guiding port 225, or the connection section 227 may also be a structure with a gradually decreasing longitudinal cross-sectional area in the direction extending from the first air guiding port 224 to the second air guiding port 225.

[0106] As can be seen from the above embodiments, the sample analysis system of the embodiments of the present invention can be used to analyze the collected samples to obtain various indicators for auxiliary diagnosis / treatment, or perform quality control detection through quality control products and calibration tests through calibration products before sample detection to ensure the accuracy and precision of the test. The substance to be tested that needs to be rewarmed can be rewarmed online in the rewarming module of the sample analysis system, and then can be scheduled by the scheduling module, so as to perform subsequent detection processes. Online rewarming can facilitate the rewarming operation after the substance to be tested is taken out, and the rewarming process is controllable, effectively reducing the risk of deterioration of the substance to be tested. For substances to be tested that need to be rewarmed in batches, the consistency of the rewarming temperature of the substances to be tested within the same batch can also be effectively guaranteed, thereby effectively ensuring the accuracy of the detection results.

[0107] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
