Description

Technical Field

[0001] The present invention relates to the field of in vitro diagnostic devices, and particularly to a sample analyzer and a magnetic separation mechanism of the sample analyzer. Background Art

[0002] A sample analyzer provided by the related art has a measurement process for a sample that includes: first, performing a magnetic separation operation on the liquid after incubation of the sample and a reagent containing magnetic beads in a reaction vessel through a magnetic separation mechanism, and then measuring a test liquid formed at least from the liquid after the magnetic separation operation in the reaction vessel through a measurement mechanism to obtain measurement information. Among them, the magnetic separation mechanism is provided with a magnetic adsorption position and a liquid suction position. The magnetic adsorption position is used for a magnet to magnetically adsorb the liquid in the reaction vessel to form a magnetic bead cluster adsorbed on the inner wall of the reaction vessel, and the liquid suction position is used for a liquid suction component to suck away the liquid in the reaction vessel except the magnetic bead cluster. In order to ensure that the magnetic bead cluster can remain adsorbed on the inner wall of the reaction vessel during the liquid suction process, a magnet is also required at the liquid suction position to adsorb the magnetic bead cluster.

[0003] In the related art, the magnets at the magnetic adsorption position and the liquid suction position adopt the same setting scheme, that is, the orientation of the magnet relative to the working position and the number of magnets are the same. For example, a single magnet is provided on one side of the magnetic adsorption position, and a single magnet is also provided on one side of the liquid suction position. However, since the design requirements of the magnets at the magnetic adsorption position and the liquid suction position are not very the same, the magnet at the magnetic adsorption position needs to adsorb the magnetic beads and the target substances bound to the magnetic beads in the reaction vessel to a designated position as quickly as possible to form a magnetic bead cluster on the inner wall of the reaction vessel, while the magnet at the liquid suction position needs to stably adsorb the magnetic beads and the target substances bound to the magnetic beads on the inner wall of the reaction vessel. That is, the design of the magnet at the magnetic adsorption position focuses more on the adsorption speed, and the design of the magnet at the liquid suction position focuses more on the adsorption stability. Therefore, if the same setting scheme is used for the magnets at the magnetic adsorption position and the liquid suction position, either the adsorption speed at the magnetic adsorption position will decrease, or the adsorption stability at the liquid suction position will decrease, or the magnets at the magnetic adsorption position and the liquid suction position will be designed more complexly and the cost will be relatively high, making it difficult to balance the adsorption speed at the magnetic adsorption position and the adsorption stability at the liquid suction position at low cost. In addition, if the adsorption speed at the magnetic adsorption position is too slow, it is easy to cause the problem that all magnetic beads cannot be aggregated to the target position within the specified time, resulting in the loss of magnetic beads and the target substances bound to the magnetic beads, and further affecting the accuracy of the measurement result. If the adsorption stability at the liquid suction position is too poor, it is easy to cause some magnetic beads and the target substances bound to the magnetic beads to fall off during the fluctuation of the liquid suction process and be sucked away by the liquid suction component with other liquids, and further cause the problem of loss of magnetic beads and the target substances bound to the magnetic beads and affecting the accuracy of the measurement result.

Detailed implementation manners

[0168] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0169] In the present invention, the descriptions involving "first", "second", etc. are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

When the combination of technical solutions results in contradictions or is unachievable, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0170] Embodiment 1:

[0171] As Figures 1 to 9 shown, the sample analyzer 10 provided in Embodiment 1 of the present invention includes a magnetic separation mechanism 100, a measurement mechanism 200, and a controller 300. The magnetic separation mechanism 100 is configured to perform a magnetic separation operation on the liquid in the reaction vessel 20. The measurement mechanism 200 is configured to measure the test liquid formed at least from the liquid after the magnetic separation operation in the reaction vessel 20 to obtain measurement information. The controller 300 is configured to: output the measurement result of the sample according to the measurement information of the measurement mechanism 200. The magnetic separation operation is mainly used to separate the liquid in the reaction vessel 20 into a test portion and an impurity portion by magnetic attraction to achieve liquid purification. The magnetic separation mechanism 100 is at least configured to perform the following actions: perform a magnetic adsorption treatment on the liquid in the reaction vessel 20, and perform a liquid suction treatment on the liquid in the reaction vessel 20. The reaction vessel 20 is used to hold the liquid containing at least the sample for magnetic separation and measurement. It should be noted that the reaction vessel 20 used to hold the liquid in the magnetic separation operation and the reaction vessel 20 used to hold the test liquid in the measurement may be the same reaction vessel 20, or two independent reaction vessels 20, that is: the magnetic separation operation may not perform a transfer operation on the test portion, so that the test portion remains in the same reaction vessel 20 for magnetic separation and measurement; or, the magnetic separation operation may also transfer the test portion from one reaction vessel 20 to another reaction vessel 20 for the measurement step.

[0172] Referring to 1 and Figure 2As shown, as an implementation, the sample analyzer 10 further includes an incubation mechanism 400 for incubating the liquid formed at least by the sample and the first reagent in the reaction vessel 20, and a magnetic separation mechanism 100 for performing a magnetic separation operation on the liquid in the reaction vessel 20 after incubation. The first reagent contains magnetic beads. The incubation mechanism 400 is mainly used to provide a suitable reaction environment (such as a temperature environment within a preset range) for the sample and the first reagent, so that the sample and the first reagent can react fully and quickly. The reaction vessel 20 used to carry the sample and the first reagent for incubation during the incubation operation and the reaction vessel 20 used to carry the liquid for magnetic separation during the magnetic separation operation can be the same reaction vessel 20, or can be two independent reaction vessels 20. Of course, in specific applications, as an alternative implementation, the sample and the first reagent can also be incubated in an incubation device independently set outside the sample analyzer 10 and then placed in the sample analyzer 10 for magnetic separation and determination.

[0173] Refer to 1 to Figure 3 As shown, as an implementation, the magnetic separation mechanism 100 includes a carrying member 140, a scheduling member 150, at least one first liquid suction member 130, at least one first magnetic member 110, and at least one second magnetic member 120. The scheduling member 150 is at least used to schedule the reaction vessel 20 loaded with the incubated liquid to the first magnetic adsorption position 1001, and to schedule the reaction vessel 20 after the first magnetic adsorption action is completed at the first magnetic adsorption position 1001 to the first liquid suction position 1002. The carrying member 140 is at least used to carry the reaction vessel 20 located at the first magnetic adsorption position 1001 and to carry the reaction vessel 20 located at the first liquid suction position 1002. The first magnetic member 110 is used to provide a magnetic field for the first magnetic adsorption position 1001 to perform a first magnetic adsorption action on the liquid in the reaction vessel 20 located at the first magnetic adsorption position 1001. The second magnetic member 120 is used to provide a magnetic field for the first liquid suction position 1002 to perform a second magnetic adsorption action on the liquid in the reaction vessel 20 located at the first liquid suction position 1002. The first liquid suction member 130 is used to perform a first liquid suction action on the liquid in the reaction vessel 20 located at the first liquid suction position 1002. The magnetic adsorption action at the first magnetic adsorption position 1001 and the liquid suction action at the first liquid suction position 1002 can be carried out in parallel, which is conducive to ensuring the magnetic separation efficiency of batch samples. The magnetic adsorption action at the first magnetic adsorption position 1001 is mainly used to adsorb the magnetic beads in the reaction vessel 20 and the target substance (the target substance here can be the analyte or can also be an interfering substance) combined with the magnetic beads to a specified position as quickly as possible to form a magnetic bead cluster 30 on the inner wall of the reaction vessel 20. The magnetic adsorption action at the first liquid suction position 1002 is mainly used to adsorb the magnetic beads in the reaction vessel 20 and the target substance combined with the magnetic beads on the inner wall of the reaction vessel 20 as stably as possible.

[0174] As an implementation manner, the first magnetic adsorption position 1001 is used to accommodate the reaction vessel 20 to perform the first magnetic adsorption action but not the liquid suction action. The first liquid suction position 1002 is used to accommodate the reaction vessel 20 to perform the second magnetic adsorption action and the first liquid suction action. That is, the liquid in the reaction vessel 20 only performs the magnetic adsorption action but not the liquid suction action at the first magnetic adsorption position 1001, and the liquid in the reaction vessel 20 at the first liquid suction position 1002 performs both the magnetic adsorption action and the liquid suction action.

[0175] Referring to Figure 3 and Figure 4 As shown, as an implementation manner, the first magnetic member 110 is used to adsorb and form at least two magnetic bead clusters 30 on the inner side wall of the reaction vessel 20 located at the first magnetic adsorption position 1001. The second magnetic member 120 is used to adsorb and form at least one magnetic bead cluster 30 on the inner side wall of the reaction vessel 20 located at the first liquid suction position 1002. The first liquid suction member 130 is used to perform the first liquid suction action on the liquid in the reaction vessel 20 located at the first liquid suction position 1002 and subjected to the second magnetic adsorption action by the first magnetic member 110. The number of magnetic bead clusters 30 adsorbed and formed by the first magnetic member 110 on the inner side wall of the reaction vessel 20 located at the first magnetic adsorption position 1001 is greater than the number of magnetic bead clusters 30 adsorbed and formed by the second magnetic member 120 on the inner side wall of the reaction vessel 20 located at the first liquid suction position 1002. The first magnetic member 110 adsorbs and forms at least two magnetic bead clusters 30 on the inner side wall of the reaction vessel 20 located at the first magnetic adsorption position 1001 mainly because the first magnetic member 110 forms at least two dispersed magnetic fields at the first magnetic adsorption position 1001. The at least two dispersed magnetic fields can adsorb the magnetic beads and the target substances combined with the magnetic beads in the reaction vessel 20 located at the first magnetic adsorption position 1001 from different directions, so that the moving distance of the adsorbed magnetic beads and the target substances combined with the magnetic beads can be shortened, and the magnetic beads and the target substances combined with the magnetic beads can be quickly and proximally adsorbed to the inner side wall of the reaction vessel 20, which is beneficial to ensuring the adsorption speed at the first magnetic adsorption position 1001. In this implementation scheme, by setting the first magnetic member 110 at the first magnetic adsorption position 1001 and the second magnetic member 120 at the first liquid suction position 1002 in different ways, and making the number of magnetic bead clusters 30 adsorbed and formed by the first magnetic member 110 in one reaction vessel 20 greater than the number of magnetic bead clusters 30 adsorbed and formed by the second magnetic member 120 in one reaction vessel 20, it is beneficial to ensure both the adsorption speed at the first magnetic adsorption position 1001 and the adsorption stability at the first liquid suction position 1002.

[0176] As an implementation manner, at least two bead clusters 30 adsorbed and formed by the first magnetic member 110 on the inner sidewall of the reaction vessel 20 located at the first magnetic adsorption position 1001 are spaced apart, that is, there is a spacing between at least two bead clusters 30 adsorbed and formed by the first magnetic member 110 and they are not connected. Of course, in specific applications, as an alternative implementation manner, at least two bead clusters 30 adsorbed and formed by the first magnetic member 110 on the inner sidewall of the reaction vessel 20 located at the first magnetic adsorption position 1001 may also be connected together at local edges.

[0177] As an implementation manner, a first magnetic adsorption position 1001 is formed between or on one side of the first magnetic members 110, that is: the first magnetic members 110 may be distributed in at least two directions of the first magnetic adsorption position 1001 along the horizontal circumferential direction, or may be distributed on one side of the first magnetic adsorption position 1001, as long as it is ensured that the magnetic field provided by the first magnetic members 110 for the first magnetic adsorption position 1001 can adsorb and form at least two bead clusters 30 on the inner sidewall of the reaction vessel 20 located at the first magnetic adsorption position 1001.

[0178] As an implementation manner, a first liquid adsorption position 1002 is formed between or on one side of the second magnetic members 120, that is: the second magnetic members 120 may be distributed in at least two directions of the first liquid adsorption position 1002 along the horizontal circumferential direction, or may be distributed on one side of the first liquid adsorption position 1002, as long as it is ensured that the magnetic field provided by the second magnetic members 120 for the first liquid adsorption position 1002 can adsorb and form at least one bead cluster 30 on the inner sidewall of the reaction vessel 20 located at the first liquid adsorption position 1002 and the number of bead clusters 30 adsorbed and formed at the first liquid adsorption position is less than the number of bead clusters 30 adsorbed and formed at the first magnetic adsorption position 1001.

[0179] As an implementation manner, the first magnetic member 110 includes two paired and spaced-apart first magnetic devices 111. A first magnetic adsorption position 1001 is formed on one side of each first magnetic device 111, that is: the first magnetic adsorption position 1001 is formed on only one side of each first magnetic device 111. Specifically, the first magnetic adsorption position 1001 is formed between the two paired and spaced-apart first magnetic devices 111 or the first magnetic adsorption position 1001 is formed on one side of the two paired and spaced-apart first magnetic devices 111. The first magnetic member 110 is configured to perform a first magnetic adsorption action on the liquid in the reaction vessel 20 located at the first magnetic adsorption position 1001 to adsorb and form two magnetic bead clusters 30 on the inner sidewall of the reaction vessel 20 located at the first magnetic adsorption position 1001. The second magnetic member 120 is composed of a single second magnetic device 121. A first liquid adsorption position 1002 is formed on one side of the single second magnetic device 121. The second magnetic member 120 is configured to perform a second magnetic adsorption action on the liquid in the reaction vessel 20 located at the first liquid adsorption position 1002 to adsorb and form a single magnetic bead cluster 30 on the inner sidewall of the reaction vessel 20 located at the first liquid adsorption position 1002. The two paired and spaced-apart first magnetic devices 111 at the first magnetic adsorption position 1001 can adsorb magnetic beads and the target substances bound to the magnetic beads from different orientations, so that the distance of adsorption and movement of the magnetic beads and the target substances bound to the magnetic beads can be shortened, enabling the magnetic beads and the target substances bound to the magnetic beads to be quickly and proximally adsorbed to the inner sidewall of the reaction vessel 20, which is beneficial to ensuring the adsorption speed at the first magnetic adsorption position 1001. In addition, the single second magnetic device 121 at the first liquid adsorption position 1002 can adsorb and aggregate all the magnetic beads and the target substances bound to the magnetic beads in the reaction vessel 20 at the first liquid adsorption position 1002 into a single magnetic bead cluster 30, which is beneficial to increasing the stability of adsorption of the magnetic beads and the target substances bound to the magnetic beads during liquid absorption.In this embodiment, the first magnetic member 110 adsorbs and forms two bead clusters 30 on the inner sidewall of the reaction vessel 20 at the first magnetic adsorption position 1001, and the second magnetic member 120 adsorbs and forms a single bead cluster 30 on the inner sidewall of the reaction vessel 20 at the first liquid adsorption position 1002, meeting the design requirement that the number of bead clusters 30 formed by the first magnetic member 110 adsorbing on the inner sidewall of the reaction vessel 20 at the first magnetic adsorption position 1001 is greater than the number of bead clusters 30 formed by the second magnetic member 120 adsorbing on the inner sidewall of the reaction vessel 20 at the first liquid adsorption position 1002. Of course, in specific applications, the number of bead clusters 30 formed by the first magnetic member 110 adsorbing on the inner sidewall of the reaction vessel 20 at the first magnetic adsorption position 1001 and the number of bead clusters 30 formed by the second magnetic member 120 adsorbing on the inner sidewall of the reaction vessel 20 at the first liquid adsorption position 1002 are not limited to this. For example, as an alternative embodiment, it is also possible to adjust the design of the first magnetic member 110 and the second magnetic member 120 so that the first magnetic member 110 adsorbs and forms three or more bead clusters 30 on the inner sidewall of the reaction vessel 20 at the first magnetic adsorption position 1001, and the second magnetic member 120 adsorbs and forms a single bead cluster 30 or two bead clusters 30 on the inner sidewall of the reaction vessel 20 at the first liquid adsorption position 1002.

[0180] Refer to 3 and Figure 4 As shown in FIG. 3, as an implementation manner, the above two paired and spaced-apart first magnetic devices 111 are arranged at intervals in the horizontal direction on opposite sides of the first magnetic adsorption position 1001. In this embodiment, the first magnetic member 110 is distributed on the opposite sides of the first magnetic adsorption position 1001, that is, one first magnetic device 111 is arranged on one side of the first magnetic adsorption position 1001, and the other first magnetic device 111 is arranged on the other side of the first magnetic adsorption position 1001. In this way, the two paired and spaced-apart first magnetic devices 111 at the first magnetic adsorption position 1001 can adsorb magnetic beads and the target substances bound to the magnetic beads from opposite sides of the reaction vessel 20, so that the distance for the magnetic beads and the target substances bound to the magnetic beads to be adsorbed and moved can be better shortened, enabling the magnetic beads and the target substances bound to the magnetic beads to be quickly and proximally adsorbed to the inner sidewall of the reaction vessel 20, which is beneficial to ensuring the adsorption speed at the first magnetic adsorption position 1001. The second magnetic member 120 is distributed on one side of the first liquid adsorption position 1002, which is beneficial to ensuring the adsorption stability of the magnetic beads and the target substances bound to the magnetic beads in the reaction vessel 20 at the first liquid adsorption position 1002.

[0181] As an implementation manner, a receiving groove for receiving the reaction vessel 20 is provided at the first magnetic adsorption position 1001, and the two paired and spaced-apart first magnetic devices 111 are arranged at intervals and opposite to each other along the radial direction of the receiving groove, that is, the two paired and spaced-apart first magnetic devices 111 are distributed on opposite sides of the receiving groove.

[0182] As an implementation manner, the above two paired and spaced first magnetic devices 111 are spaced on opposite sides of the first magnetic attraction position 1001 along a diameter direction of the same reaction vessel 20. Two magnetic bead clusters 30 adsorbed and formed by the first magnetic member 110 on the inner sidewall of the reaction vessel 20 at the first magnetic attraction position 1001 are spaced along the diameter direction of the reaction vessel 20 and distributed on opposite sides of the reaction vessel 20.

[0183] As an implementation manner, the scheduling member 150 is configured to drive the bearing member 140 to drive the reaction vessel 20 to move to the first magnetic attraction position 1001 and the first liquid suction position 1002 in sequence; the two first magnetic devices 111 are respectively arranged on opposite sides of the movement track of the scheduling member 150 driving the reaction vessel 20 to move (the movement track described below, unless otherwise specified, refers to the movement track of the scheduling member 150 driving the reaction vessel 20 to move), and the second magnetic device 121 is arranged on one side of the movement track. In this implementation scheme, the scheduling mechanism drives the bearing member 140 to move, so that the bearing member 140 drives the reaction vessel 20 to move to the first magnetic attraction position 1001 and the first liquid suction position 1002 respectively. In this way, the scheduling member 150 does not need to perform the actions of clamping and releasing the reaction vessel 20, which is beneficial to simplifying the structure of the scheduling member 150 and improving the efficiency of the scheduling member 150 in scheduling the reaction vessel 20. Of course. In specific applications, as an alternative implementation scheme, the scheduling member 150 can also be designed to drive the reaction vessel 20 to move to the first magnetic attraction position 1001 and the first liquid suction position 1002 respectively by clamping and moving the reaction vessel 20. For example, the scheduling member 150 includes a jaw for clamping the reaction vessel 20 and a power member for driving the jaw to move.

[0184] As an implementation manner, the scheduling member 150 is configured to drive the bearing member 140 to drive the reaction vessel 20 loaded with the incubated liquid to move to the first magnetic attraction position 1001 and the first liquid suction position 1002 in sequence.

[0185] As an implementation manner, the carrier member 140 is disc-shaped, and a plurality of accommodating grooves are formed in the carrier member 140 and arranged along the circumferential direction of the disc-shaped carrier member 140. The circumferential direction of the disc-shaped carrier member 140 is horizontally arranged, and the plurality of accommodating grooves are arranged in the horizontal direction. Each accommodating groove is used to accommodate a reaction vessel 20, and the scheduling member 150 is used to drive the carrier member 140 to drive the reaction vessel 20 to horizontally rotate around the central axis of the carrier member 140, so that the reaction vessel 20 accommodated in the accommodating groove is sequentially scheduled to the first magnetic attraction position 1001 and the first liquid suction position 1002. The movement track of the scheduling member 150 driving the reaction vessel 20 is a circular track, and the first magnetic attraction position 1001 and the first liquid suction position 1002 are distributed along the circular movement track. Specifically, when the scheduling member 150 drives the carrier member 140 to rotate, the reaction vessel 20 on the carrier member 140 can sequentially pass through the first magnetic attraction position 1001 and the first liquid suction position 1002. Of course, in specific applications, the shape of the carrier member 140 is not limited to this, and the movement track of the scheduling member 150 driving the reaction vessel 20 is not limited to this. For example, as an alternative implementation manner, the movement track of the scheduling member 150 driving the reaction vessel 20 is a straight track, and the first magnetic attraction position 1001 and the first liquid suction position 1002 are distributed along the straight track; or, as another alternative implementation manner, the movement track of the scheduling member 150 driving the reaction vessel 20 is a bent line track, and the first magnetic attraction position 1001 and the first liquid suction position 1002 are distributed along the bent line track. As an implementation manner, the number of the first magnetic attraction positions 1001 is at least two, and the number of the first magnetic members 110 is at least two and the movement tracks are arranged in sequence, that is: the magnetic separation mechanism 100 includes at least two first magnetic members 110 arranged in sequence along the movement track, and each first magnetic member 110 correspondingly forms at least one first magnetic attraction position 1001. In this implementation manner, the number of the first magnetic attraction positions 1001 is at least two, so that the liquid in the reaction vessel 20 undergoes at least two stages of first magnetic adsorption actions before reaching the first liquid suction position 1002 to perform the first liquid suction action, which is beneficial to the parallel operation of a plurality of reaction vessels 20.

[0186] As an implementation manner, the number of the first liquid suction positions 1002 is at least two, and the number of the second magnetic members 120 is at least two and the movement tracks are arranged in sequence, that is: the magnetic separation mechanism 100 includes at least two second magnetic members 120 arranged in sequence along the movement track, and each second magnetic member 120 correspondingly forms at least one first liquid suction position 1002. In this implementation manner, the number of the first liquid suction positions 1002 is at least two, so that the liquid in the reaction vessel 20 undergoes at least two stages of first liquid suction actions in one magnetic separation operation, which is beneficial to ensuring the purification effect of the liquid in the reaction vessel 20.

[0187] Refer to 1 to Figure 3 、 Figure 6 andFigure 7 As shown, as an implementation manner, two paired and spaced first magnetic devices 111 are respectively disposed on opposite sides of the movement track. The magnetic separation mechanism 100 further includes a main bracket, a first mounting bracket 1061 and a second mounting bracket 1071, and the first mounting bracket 1061 and the second mounting bracket 1071 are respectively connected to the main bracket. The first mounting bracket and the second mounting bracket 1071 are respectively located on opposite sides of the movement track. The first mounting bracket 1061 is used to carry all the first magnetic devices 111 and all the second magnetic devices 121 disposed on one side of the movement track to form a first module 106, and the second mounting bracket 1071 is used to carry all the first magnetic devices 111 disposed on the other side of the movement track to form a second module 107. The first module 106 is connected to the main bracket through the first mounting bracket 1061, and the second module 107 is connected to the main bracket through the second mounting bracket 1071. In this implementation scheme, the magnetic devices on opposite sides of the movement track are designed and installed in modules, that is, all the magnetic devices on the same side of the movement track are installed on one mounting bracket as a module and installed on the main bracket together. In this way, it is beneficial to reduce the difficulty of installing the magnetic devices and the difficulty of later maintenance.

[0188] As an implementation manner, each first magnetic member 110 is composed of a first magnetic device 111 disposed on the first side of the movement track and a first magnetic device 111 disposed on the second side of the movement track, and each second magnetic member 120 is composed of a single second magnetic device 121 disposed on the first side, and the first side and the second side are respectively located on opposite sides of the movement track. The first mounting bracket 1061 is used to carry all the first magnetic devices 111 and all the second magnetic devices 121 disposed on the first side, and forms a first module 106 with all the first magnetic devices 111 and all the second magnetic devices 121 disposed on the first side. The second mounting bracket 1071 is used to carry all the first magnetic devices 111 disposed on the second side, and forms a second module 107 with all the first magnetic devices 111 disposed on the second side. The first module 106 is installed on the first side and is connected to the main bracket through the first mounting bracket 1061, and the second module 107 is installed on the second side and is connected to the main bracket through the second mounting bracket 1071.

[0189] As an implementation manner, the first magnetic device 111 is composed of at least two first magnets 1111. In this implementation scheme, the first magnetic device 111 is composed of at least two first magnets 1111, and each first magnet 1111 can form a magnetic field. By superimposing the magnetic fields of at least two first magnets 1111, it is beneficial to strengthen the magnetic attraction force, thereby being beneficial to improving the magnetic adsorption effect and efficiency.

[0190] As an implementation manner, the first magnetic device 111 is composed of at least two adjacent and paired first magnets 1111. One ends of two adjacent and paired first magnets 1111 that are close to the first magnetic attraction position 1001 are abutted against each other, or one sides of two adjacent and paired first magnets 1111 are in contact with each other.

[0191] As an implementation manner, at least two adjacent and paired first magnets 1111 of the same first magnetic device 111 are abutted against each other in sequence, that is: at least a part of any two adjacent first magnets 1111 in the same first magnetic device 111 are abutted against each other, so that the magnetic fields of two adjacent first magnets 1111 can be superimposed to enhance the magnetic attraction force. Of course, in specific applications, as an alternative implementation manner, there may also be a small distance, such as a distance less than 10 mm, between two adjacent first magnets 1111 of the same first magnetic device 111.

[0192] As an implementation manner, the first magnetic device 111 is composed of at least two adjacent and paired first magnets 1111, including: the first magnetic device 111 is composed of two first magnets 1111 with at least one end abutted against each other. The first magnetic device 111 is composed of two first magnets 1111 with at least one end abutted against each other, including any of the following situations: the first magnetic device 111 is composed of two first magnets 1111 stacked vertically (this also belongs to the situation where one sides of two adjacent and paired first magnets 1111 are in contact with each other), the first magnetic device 111 is composed of two first magnets 1111 abutted against each other along the horizontal circumferential direction, and the first magnetic device 111 is composed of two first magnets 1111 abutted against each other along the inclined direction. In this implementation manner, the number of first magnets 1111 constituting the first magnetic device 111 is two, which not only enhances the magnetic attraction force of the first magnetic device 111, but also helps to avoid the problem of increased cost caused by too many first magnets 1111. Of course, in specific applications, as an alternative implementation manner, the first magnetic device 111 may also be composed of three or more first magnets 1111 with at least one end abutted against each other.

[0193] As an implementation manner, the second magnetic device 121 is composed of at least two second magnets 1211. In this implementation manner, the second magnetic device 121 is composed of at least two second magnets 1211, and each second magnet 1211 can form a magnetic field. By superimposing the magnetic fields of at least two second magnets 1211, it is beneficial to enhance the magnetic attraction force, thereby improving the magnetic adsorption effect and efficiency.

[0194] As an implementation manner, the second magnetic device 121 is composed of at least two adjacent and paired second magnets 1211. One ends of two adjacent and paired second magnets 1211 close to the first liquid suction position 1002 are abutted against each other, or one sides of two adjacent and paired second magnets 1211 are in contact with each other.

[0195] As an implementation manner, at least two adjacent and paired second magnets 1211 of the same second magnetic device 121 are abutted in sequence, that is: at least partially, any two adjacent second magnets 1211 in the same second magnetic device 121 are abutted against each other, so that the magnetic fields of two adjacent second magnets 1211 can be superimposed to enhance the magnetic suction force. Of course, in specific applications, as an alternative implementation manner, there may also be a small distance, such as a distance less than 10 mm, between two adjacent second magnets 1211 of the same second magnetic device 121.

[0196] As an implementation manner, the second magnetic device 121 is composed of at least two adjacent and paired second magnets 1211 includes: the second magnetic device 121 is composed of two second magnets 1211 with at least one end abutted against each other. The second magnetic device 121 is composed of two second magnets 1211 with at least one end abutted against each other includes any of the following situations: the second magnetic device 121 is composed of two second magnets 1211 stacked in the vertical direction (this also belongs to the situation where one sides of two adjacent and paired second magnets 1211 are in contact with each other), the second magnetic device 121 is composed of two second magnets 1211 abutted against each other in the horizontal circumferential direction, and the second magnetic device 121 is composed of two second magnets 1211 abutted against each other in the inclined direction. In this implementation manner, the number of second magnets 1211 constituting the second magnetic device 121 is two, which not only enhances the magnetic suction force of the second magnetic device 121, but also helps to avoid the problem of increased cost caused by too many second magnets 1211. Of course, in specific applications, as an alternative implementation manner, the second magnetic device 121 may also be composed of three or more second magnets 1211 with at least one end abutted against each other, as long as it is ensured that the number of magnetic bead clusters 30 adsorbed by the second magnetic member 120 on the inner side wall of a reaction vessel 20 located at the first liquid suction position 1002 is less than the number of magnetic bead clusters 30 adsorbed by the first magnetic member 110 on the inner side wall of a reaction vessel 20 located at the first magnetic suction position 1001.

[0197] Refer to Figures 4 to 6As shown, as an implementation manner, the first magnetic device 111 is composed of two first magnets 1111 stacked vertically. The second magnetic device 121 is composed of two second magnets 1211 stacked vertically. With this setting scheme, on the premise of enhancing the magnetic attraction force between the first magnetic device 111 and the second magnetic device 121, it is also beneficial to reduce the horizontal space occupied by the first magnetic device 111 and the second magnetic device 121.

[0198] As an implementation manner, the first magnet 1111 forms two magnetic poles, namely the N pole and the S pole. The two magnetic poles of the first magnet 1111 are respectively located at opposite ends of the first magnet 1111. The second magnet 1211 forms two magnetic poles, namely the N pole and the S pole. The two magnetic poles of the second magnet 1211 are respectively located at opposite ends of the second magnet 1211.

[0199] As an implementation manner, the two magnetic poles of the same first magnet 1111 are arranged horizontally, that is, the N pole and the S pole of the same first magnet 1111 are horizontally placed, and the N pole is on the left or right or front or back of the S pole. One magnetic pole of the first magnet 1111 faces the first magnetic attraction position 1001, and the other magnetic pole extends horizontally away from the first magnetic attraction position 1001. For example, the first magnet 1111 is arranged with the N pole facing the first magnetic attraction position 1001 and the S pole facing away from the first magnetic attraction position 1001 horizontally; or, the first magnet 1111 is arranged with the S pole facing the first magnetic attraction position 1001 and the N pole facing away from the first magnetic attraction position 1001 horizontally. Of course, in specific applications, the two magnetic poles of the first magnet 1111 are not limited to being horizontally arranged. For example, as an alternative implementation scheme, the two magnetic poles of the same first magnet 1111 are arranged vertically, that is, the N pole and the S pole of the same first magnet 1111 are vertically placed, and the N pole is above or below the S pole; or, as another alternative implementation scheme, the two magnetic poles of the same first magnet 1111 are arranged obliquely, that is, the N pole and the S pole of the same first magnet 1111 are placed in an oblique straight line, and the N pole is diagonally above or below the S pole.

[0200] As an implementation manner, the two magnetic poles of the same second magnet 1211 are arranged in the horizontal direction, that is, the N pole and the S pole of the same second magnet 1211 are horizontally placed, and the N pole is on the left or right or front or back side of the S pole. Of course, in specific applications, the two magnetic poles of the second magnet 1211 are not limited to being horizontally arranged. For example, as an alternative implementation manner, the two magnetic poles of the same second magnet 1211 are arranged in the vertical direction, that is, the N pole and the S pole of the same second magnet 1211 are vertically placed, and the N pole is above or below the S pole; or, as another alternative implementation manner, the two magnetic poles of the same second magnet 1211 are arranged in the inclined direction, that is, the N pole and the S pole of the same second magnet 1211 are placed in an inclined straight line, and the N pole is diagonally above or diagonally below the S pole.

[0201] As an implementation manner, the polarities of the magnetic poles of the two first magnets 1111 stacked in the vertical direction in the same first magnetic device 111 facing the same first magnetic attraction position 1001 are opposite, and the polarities of the magnetic poles of the two second magnets 1211 stacked in the vertical direction in the same second magnetic device 121 facing the same first liquid suction position 1002 are opposite. For example, one first magnet 1111 in the same first magnetic device 111 faces the first magnetic attraction position 1001 with the N pole, and the other first magnet 1111 faces the first magnetic attraction position 1001 with the S pole. One second magnet 1211 in the same second magnetic device 121 faces the first liquid suction position 1002 with the N pole, and the other second magnet 1211 faces the first liquid suction position 1002 with the S pole. In this way, the principle of attraction between opposite sexes can be used to facilitate the installation of the first magnetic device 111 and the second magnetic device 121. Of course, in specific applications, as an alternative implementation manner, the polarities of the magnetic poles of the two first magnets 1111 stacked in the vertical direction in the same first magnetic device 111 facing the same first magnetic attraction position 1001 can also be set to be the same, and the polarities of the magnetic poles of the two second magnets 1211 stacked in the vertical direction in the same second magnetic device 121 facing the same first liquid suction position 1002 can be set to be the same. In order to prevent the two first magnets 1111 from repelling and shifting, and the two second magnets 1211 from repelling and shifting, other limiting structural members can be added to limit the two first magnets 1111 and the second magnets 1211.

[0202] As an implementation manner, among two paired and spaced-apart first magnetic devices 111 of the same first magnetic component 110, the polarities of the two first magnets 1111 distributed on opposite sides of the same first magnetic attraction position 1001 and at the same height position and facing the same first magnetic attraction position 1001 are the same, that is: among two paired and spaced-apart first magnetic devices 111, the polarities of the two first magnets 1111 distributed on the same layer and facing the same first magnetic attraction position 1001 are the same. In this way, it is beneficial to better shorten the distance for the magnetic beads and the target substances combined with the magnetic beads to be adsorbed and moved, and further beneficial to further improve the adsorption speed.

[0203] Refer to 3 and Figure 4As shown, as an implementation manner, two paired and spaced-apart first magnetic devices 111 are horizontally spaced apart on opposite sides of the first magnetic attraction position 1001, and a single second magnetic device 121 is disposed on one side of the first magnetic attraction position 1002. The first magnetic device 111 is composed of two first magnets 1111 stacked vertically, and the second magnetic device 121 is composed of two second magnets 1211 stacked vertically; the two magnetic poles of the same first magnet 1111 are arranged horizontally, and the two magnetic poles of the same second magnet 1211 are arranged horizontally; the polarities of the magnetic poles of the two first magnets 1111 stacked vertically in the same first magnetic device 111 facing the same first magnetic attraction position 1001 are opposite, and the polarities of the magnetic poles of the two second magnets 1211 stacked vertically in the same second magnetic device 121 facing the same first magnetic attraction position 1002 are opposite; in the two paired and spaced-apart first magnetic devices 111 of the same first magnetic component 110, the polarities of the magnetic poles of the two first magnets 1111 distributed on opposite sides of the same first magnetic attraction position 1001 and at the same height position facing the same first magnetic attraction position 1001 are the same. The contact between the two first magnets 1111 is such that the two magnetic poles of one first magnet 1111 respectively contact the two magnetic poles of the other first magnet 1111 in a manner with opposite polarities, and the contact between the two second magnets 1211 is such that the two magnetic poles of one second magnet 1211 respectively contact the two magnetic poles of the other second magnet 1211 in a manner with opposite polarities. For example: the N pole of the upper first magnet 1111 contacts the S pole of the lower first magnet 1111, and the N pole of the upper second magnet 1211 contacts the S pole of the lower second magnet 1211. At this time, one side of the two first magnets 1111 contacts each other (i.e., the upper side of one first magnet 1111 contacts the lower side of the other first magnet 1111), and one side of the two second magnets 1211 contacts each other (i.e., the upper side of one second magnet 1211 contacts the lower side of the other second magnet 1211). By adopting this setting method, the rapid adsorption requirement of the first magnetic attraction position 1001 and the stable adsorption requirement of the first magnetic attraction position 1002 can be taken into account at a very low cost.

[0204] As an implementation manner, the height position of the first magnetic member 110 is lower than the height position of the second magnetic member 120. In this way, the distance between the magnetic bead cluster 30 adsorbed and formed by the second magnetic member 120 at the first liquid suction level 1002 and the bottom of the reaction vessel 20 can be increased, so that the magnetic bead cluster 30 adsorbed and formed at the first liquid suction level 1002 is far away from the bottom of the reaction vessel 20, which is more conducive to preventing the adverse phenomenon that the magnetic bead cluster 30 falls off and is sucked away by the first liquid suction member 130 when the first liquid suction member 130 sucks liquid. Of course, in specific applications, as an alternative implementation manner, the height position of the first magnetic member 110 and the height position of the second magnetic member 120 can also be set to be the same.

[0205] As an implementation manner, at least two first magnetic suction positions 1001 are formed on one side of each first magnetic device 111 and are distributed in sequence along the movement track of the scheduling member 150 driving the reaction vessel 20 to move. A first magnetic member 110 is used to perform a first magnetic adsorption action on the liquid in the reaction vessel 20 located at at least two first magnetic suction positions 1001 to respectively adsorb and form two magnetic bead clusters 30 on the inner side walls of the reaction vessels 20 located at at least two first magnetic suction positions 1001. The scheduling member 150 is used to drive the bearing member 140 to drive the reaction vessel 20 loaded with the incubated liquid to move along a preset track to at least two first magnetic suction positions 1001 in sequence. In this implementation manner, the same first magnetic member 110 provides a magnetic field at at least two first magnetic suction positions 1001, which is conducive to reducing the number of first magnetic members 110, thereby facilitating the reduction of the installation difficulty of the first magnetic member 110. Of course, in specific applications, as an alternative implementation manner, only one first magnetic suction position 1001 can also be formed on one side of each first magnetic device 111.

[0206] As an implementation manner, at least two first magnetic suction positions 1001 distributed in sequence along the movement track of the scheduling member 150 driving the reaction vessel 20 to move are arranged between two paired and spaced-apart first magnetic devices 111, that is: at least two first magnetic suction positions 1001 distributed in sequence along the movement track of the scheduling member 150 driving the reaction vessel 20 to move are formed between two paired and spaced-apart first magnetic devices 111. Of course, in specific applications, as an alternative implementation manner, only one first magnetic suction position 1001 can also be formed between two paired and spaced-apart first magnetic devices 111.

[0207] As an implementation manner, at least two first liquid suction positions 1002 are formed on one side of a single second magnetic device 121, which are sequentially distributed along the movement track of the scheduling member 150 driving the reaction vessel 20 to move. A second magnetic member 120 is used to perform a second magnetic adsorption action on the liquid in the reaction vessel 20 located at at least two first liquid suction positions 1002 to respectively adsorb and form a single magnetic bead group 30 on the inner side walls of the reaction vessels 20 located at at least two first liquid suction positions 1002. The scheduling member 150 is used to drive the carrying member 140 to drive the reaction vessel 20 loaded with the liquid after the first magnetic adsorption action to be sequentially scheduled to at least two first liquid suction positions 1002 along a preset track. In this implementation scheme, the same second magnetic member 120 provides a magnetic field at at least two first liquid suction positions 1002, which is beneficial to reducing the number of second magnetic members 120, thereby facilitating the reduction of the installation difficulty of the second magnetic member 120. Of course, in specific applications, as an alternative implementation scheme, only one first liquid suction position 1002 may also be formed on one side of a single second magnetic device 121.

[0208] Refer to FIGS. 1 to Figure 3 As shown, as an implementation manner, the magnetic separation mechanism 100 further includes at least one third magnetic member 160, and the third magnetic member 160 is composed of a single third magnetic device 161. A second magnetic suction position 1003 is formed on one side of the single third magnetic device 161. The third magnetic member 160 is used to perform a third magnetic adsorption action on the liquid in the reaction vessel 20 located at the second magnetic suction position 1003 to adsorb and form a single magnetic bead group 30 on the inner side wall of the reaction vessel 20 located at the second magnetic suction position 1003. The above-mentioned scheduling member 150 schedules the reaction vessel 20 after the first magnetic adsorption action to the first liquid suction position 1002, including: first scheduling the reaction vessel 20 after the first magnetic adsorption action to the second magnetic suction position 1003, and then scheduling the reaction vessel 20 after the third magnetic adsorption action to the first liquid suction position 1002. In this implementation scheme, after two magnetic bead groups 30 are quickly adsorbed and formed at the first magnetic suction position 1001 by the first magnetic member 110, first, the two magnetic bead groups 30 are adsorbed and aggregated to form a single magnetic bead group 30 at the second magnetic suction position 1003 by the third magnetic member 160, so that after a single magnetic bead group 30 is firmly adsorbed, magnetic adsorption and liquid suction are performed at the first liquid suction position 1002, thereby further ensuring the firm adsorption of the magnetic bead group 30 during liquid suction.

[0209] As an implementation manner, the first magnetic suction position 1001, the second magnetic suction position 1003, and the first liquid suction position 1002 are sequentially distributed along the movement track of the scheduling member 150 driving the reaction vessel 20 to move. In this implementation scheme, the second magnetic suction position 1003 is arranged between the first magnetic suction position 1001 and the first liquid suction position 1002 along an arc track.

[0210] As an embodiment, the third magnetic device 161 is arranged on one side of the motion trajectory of the reaction container 20 driven by the scheduling component 150, and the second magnetic device 121 is also arranged on this side of the motion trajectory, that is, all the third magnetic devices 161 and all the second magnetic devices 121 are arranged on the same side of the motion trajectory of the reaction container 20 driven by the scheduling component 150. In this way, the reaction container 20 can move from the second magnetic suction position 1003 to the first liquid suction position 1002 without changing the direction to adsorb the magnetic bead group 30.

[0211] As an embodiment, each third magnetic component 160 is composed of a single third magnetic device 161 arranged on the first side, and the first mounting frame 1061 is used to support all the first magnetic devices 111, all the second magnetic devices 121 and all the third magnetic devices 161 arranged on the first side, and form a first module 106 together with all the first magnetic devices 111, all the second magnetic devices 121 and all the third magnetic devices 161 arranged on the first side.

[0212] As an implementation mode, the third magnetic device 161 is composed of one or at least two third magnets. In addition to the different arrangement positions of the third magnetic device 161 and the second magnetic device 121, the third magnetic device 161 can be constructed in the same arrangement as the second magnetic device 121. For example, the number, distribution, and polarity orientation of the third magnets in the third magnetic device 161 can refer to the number, distribution, and polarity orientation of the second magnets 1211 in the second magnetic device 121, which will not be described in detail here.

[0213] As an embodiment, the first liquid suction component 130 includes a first liquid suction needle and a first liquid suction power component for driving the first liquid suction needle to perform liquid suction.

[0214] Refer to 1 to Figure 3 , Figure 8 and Figure 9As shown, as an implementation manner, the magnetic separation mechanism 100 further includes at least one first liquid injection member, at least one mixing member 180, at least one fourth magnetic member 190, at least one fifth magnetic member 101, and at least one second liquid suction member 102.

[0262] Embodiment 2:

[0263] Referring to Figures 1 to 5 、 Figure 7 and Figure 10 As shown, the main difference between the sample analyzer 10 and the magnetic separation mechanism 100 provided in this embodiment and those in Embodiment 1 lies in the different distribution modes of two paired and spaced first magnetic devices 111, specifically: in Embodiment 1, two paired and spaced first magnetic devices 111 are spaced and oppositely arranged along the radial direction of the accommodation groove, that is, two paired and spaced first magnetic devices 111 are horizontally spaced on opposite sides of the first magnetic adsorption position 1001; while in this embodiment, two paired and spaced first magnetic devices 111 are spaced and vertically arranged along the axial direction of the accommodation groove, that is, two paired and spaced first magnetic devices 111 are vertically spaced on one side of the first magnetic adsorption position 1001.

[0264] Specifically, in this embodiment, a first magnetic adsorption position 1001 is formed on one side of the first magnetic member 110, and the first magnetic member 110 is used to perform a first magnetic adsorption action on the liquid in the reaction vessel 20 at the first magnetic adsorption position 1001 to adsorb and form two magnetic bead clusters 30 on the inner side wall of the reaction vessel 20 at the first magnetic adsorption position 1001.
