As a result, during the subsequent reagent aspiration process, the reagent needle may collide with the reagent cavity puncture membrane and trigger an alarm, causing the test to be terminated. In severe cases, the reagent needle may also be damaged. Summary of the Invention

[0036] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below with reference to the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0037] An embodiment of the present application provides a sample analyzer. Figure 1 This is a schematic diagram of the structure of a sample analyzer provided in an embodiment of the present application. Figure 1 As shown, the sample analyzer includes: a reagent storage device 1, a correction device 2 and a driving device (not shown in the figure); wherein,

[0038] The reagent storage device 1 includes a reagent holder 10, which includes a plurality of reagent positions 100 for storing reagent bottles;

[0039] The correction device 2 includes a guide surface 20 located above the reagent position;

[0040] The driving device is in transmission connection with the correction device 2 or the reagent holder 10. The driving device is used to drive one of the correction device 2 and the reagent holder 10 to move relative to the other, so that the reagent bottle 101 that is not loaded into place on the reagent holder 10 contacts the guide surface 20 and is loaded into place under the push of the guide surface 20.

[0041] It should be noted that, in the embodiments of the present application, Figure 1 As shown, the reagent storage device 1 includes a reagent holder 10, which is a disc-shaped structure with a plurality of reagent positions 100 provided thereon, each of which can be loaded with a reagent bottle. In addition, the reagent holder 10 can also be a linear structure, or of course, other types of structures. The specific structure of the reagent holder 10 and the number of reagent positions 100 are not limited in this embodiment of the application.

[0042] It should be noted that in the embodiment of the present application, the driving device is connected to one of the reagent holder 10 and the correction device 2 in a transmission manner, so that the driving device can drive the device connected thereto to move relative to the other device. During the movement, each reagent position 100 can pass through the correction device 2, so that under the action of the correction device 2, the reagent bottle 101 that is not loaded into place on the reagent position 100 is corrected and loaded into place. The device connected to the driving device in the reagent holder 10 and the correction device 2 can be set according to actual needs and application scenarios, and the embodiment of the present application is not limited thereto.

[0043] Specifically, in the embodiments of the present application, Figure 1 As shown, the reagent storage device 1 further includes a fixing seat 11. The correction device 2 can be mounted on the fixing seat 11, and the driving device can be in transmission connection with the reagent seat 10, and the driving device is used to drive the reagent seat 10 to rotate relative to the fixing seat 11 so that each reagent position 100 passes through the correction device 2.

[0044] It should be noted that, in the embodiments of the present application, Figure 1 As shown, the reagent position 100 is loaded with a reagent bottle 101 containing a magnetic bead liquid container. When loaded in place, the magnetic bead liquid container is actually suspended and is not stuck in the interior of the reagent seat 10. The reagent storage device 1 also includes a gear ring 12, which is provided on the fixed seat 11 and is located in the enclosed area of ​​the reagent seat 10. The gear ring 12 extends into the loading area of ​​the magnetic bead liquid container on the reagent seat 10 to engage with the gear on the magnetic bead liquid container. When the driving device drives the reagent seat 10 to rotate around the gear ring 12, the gear ring 12 can drive the magnetic bead liquid container on the reagent bottle loaded in place to rotate.

[0045] It can be understood that in the embodiment of the present application, when the sample analyzer is a chemiluminescence immunoassay analyzer, the reagent bottle loaded on the reagent seat 10 includes a magnetic bead liquid container, and a gear is provided at the bottom of the magnetic bead liquid container, which is opposite to the gear ring 12 of the reagent storage device 1. In this way, when the reagent seat 10 rotates around the gear 12, for the reagent bottle loaded in place, the gear of its magnetic bead liquid container is engaged with the gear ring 12. Under the action of the gear ring 12, its magnetic bead liquid container can rotate on its own, so that the magnetic beads inside the magnetic bead liquid container can be evenly distributed in the solution, thereby ensuring the accuracy of the sample analysis results.

[0046] It should be noted that, in the embodiment of the present application, the reagent bottle 101 that is not loaded into place may be as follows: Figure 2 and Figure 3 The forward tilted state shown in FIG. Figure 4 and Figure 5 The specific posture of the reagent bottle 101 that has not been loaded into place is not limited in this embodiment of the application.

[0047] It can be understood that in the embodiment of the present application, for the reagent bottle 101 that is not loaded into place, its height in the tilted state is higher than that in the loaded state, and the guide surface 20 included in the correction device 2 is located above the reagent position 100. Therefore, when it passes through the guide surface 20, the guide surface 20 will exert a downward pressure on it, thereby loading it into place.

[0048] It should be noted that, in the embodiment of the present application, the guide surface 20 included in the correction device 2 is an inclined surface or a curved surface.

[0049] It can be understood that in the embodiment of the present application, the guide surface 20 is an inclined surface or a curved surface. When the reagent bottle 101 that has not been loaded into place actually contacts the guide surface 20, it first contacts the higher part of the guide surface 20, and gradually contacts the lower part of the guide surface 20 with relative movement. The downward pressure of the guide surface 20 on the reagent bottle 101 that has not been loaded into place gradually increases.

[0050] It should be noted that, in the embodiments of the present application, Figures 2 to 5 As shown, the correction device 2 further includes: a first support arm 21 in the horizontal direction, and a second support arm 22 in the vertical direction;

[0051] The first support arm 21 is connected to the second support arm 22;

[0052] The first support arm 21 includes a guide surface 20;

[0053] When the correction device 2 and the reagent holder 10 move relative to each other, the guide surface 20 is used to press down the reagent bottle 101 that is not loaded into place in the vertical direction.

[0054] It is understood that in the embodiments of the present application, Figures 2 to 5 As shown, the correction device 2 actually further includes an L-shaped support mechanism, wherein the first support arm 21 in the horizontal direction includes a guide surface 20 , and the guide surface 20 is arranged on the inner side of the first support arm 21 and faces the reagent seat 10 .

[0055] It should be noted that, in the embodiments of the present application, Figures 2 to 5 As shown, the structure in which the guide surface 20 is provided on the first support arm 21 is merely an exemplary structure. The correction device 2 may also include a mechanism of other shapes or structures, and the guide surface 20 need only be provided on the horizontal portion of the mechanism, facing the reagent holder 10. The specific arrangement of the guide surface 20 can be set according to actual needs and is not limited in the present embodiment.

[0056] Specifically, in the embodiments of the present application, Figure 6 As shown, the guide surface 20 includes: a first guide surface 201 and a second guide surface 202;

[0057] The first support arm 21 further includes: a horizontal surface 211;

[0058] The first guide surface 201 is connected to the first side 2111 of the horizontal surface 211, and the second guide surface 202 is connected to the second side 2112 of the horizontal surface 211. The first side 2111 is parallel to the second side. The first guide surface 201 is inclined upward from the first side 2111 toward the direction away from the second side 2112, and the second guide surface 202 is inclined upward from the second side 2112 toward the direction away from the first side 2111.

[0059] It is understood that in the embodiments of the present application, Figure 6 As shown, in the first support arm 21, the two parallel sides of the horizontal plane 211 are each connected to an inclined surface, each inclined surface extends outward along the connected side and is inclined upward, and the two inclined surfaces are respectively the first guide surface 201 and the second guide surface 202. In this way, if the reagent holder 10 moves from right to left relative to the correction device 2, that is, the reagent bottle 101 that is not loaded into place actually contacts the first guide surface 201, and is thus loaded into place under the push of the first guide surface 201; if the reagent holder 10 moves from left to right relative to the correction device 2, that is, the reagent bottle 101 that is not loaded into place actually contacts the second guide surface 202, and is thus loaded into place under the push of the second guide surface 202. Specifically, the guide surface of the first guide surface 201 and the second guide surface 202 that contacts the reagent bottle 101 that is not loaded into place depends on the movement direction of the reagent holder 10 relative to the correction device 2, and the embodiment of the present application does not limit it.

[0060] It should be noted that, in the embodiments of the present application, Figure 6As shown, the guide surface 20 can be the structure including the first guide surface 201 and the second guide surface 202 as described above. Of course, it can also be a single independent inclined or curved surface. In this way, the direction of movement of the correcting device 2 or the reagent holder 10 driven by the driving device needs to correspond to the inclined direction of the guide surface 20, so that the corrective action can be performed. The specific guide surface 20 can be set according to actual needs and application scenarios, and is not limited in the embodiments of this application.

[0061] Specifically, in an embodiment of the present application, a second snap-fitting component is provided on the reagent position 100 for snap-fitting connection with the first snap-fitting component on the reagent bottle 101, and the driving device is used to drive one of the correction device 2 and the reagent seat 10 to move relative to the other, so that the guide surface 20 pushes the reagent bottle that is not loaded into place, thereby snap-fitting connection of the first snap-fitting component with the second snap-fitting component.

[0062] It can be understood that in the embodiment of the present application, a first snap-fit ​​component is provided on each reagent position 100 on the reagent holder 10, and a corresponding second snap-fit ​​component is provided on each loaded reagent bottle. When the first snap-fit ​​component and the second snap-fit ​​component are snapped into place, the corresponding reagent bottle is loaded into place. When the first snap-fit ​​component and the second snap-fit ​​component are not snapped into place, the corresponding reagent bottle is not loaded into place.

[0063] Specifically, in the embodiments of the present application, Figure 7 As shown, the first engaging component includes a first front buckle 1011 and a rear spring buckle 1012 , and the second engaging component includes a second front buckle 1001 and a rear buckle 1002 ;

[0064] The first front buckle 1011 is used for buckling connection with the second front buckle 1001, and the rear spring buckle 1012 is used for buckling connection with the rear buckle 1002;

[0065] The driving device is used to drive one of the correction device 2 and the reagent holder 10 to move relative to the other, so that the guide surface 20 pushes the reagent bottle 101 that is not loaded into place, so that the first front buckle 1011 is buckled into the second front buckle 1001, and the rear spring buckle 1012 is buckled into the rear buckle 1002.

[0066] It should be noted that, in the embodiment of the present application, the first engaging member and the second engaging member may each include two sets of corresponding matching mechanisms to achieve a snap connection, such as Figure 7 In addition, the first and second engaging members may also be configured to include a specific number of groups to implement a snap-on connection mechanism, rather than being limited to the aforementioned one group of snaps and one group of springs. The specific configuration of the first and second engaging members may be determined based on actual needs and application scenarios, and is not limited in this embodiment of the present application.

[0067] It should be noted that, in the embodiments of the present application, Figure 7 As shown, the position of the first front buckle 1011 on the reagent bottle 101 corresponds to the position of the second front buckle 1001 on the reagent position 100, and the position of the rear spring buckle 1012 on the reagent bottle 101 corresponds to the position of the rear buckle 1002 on the reagent position 100. The position of the first front buckle 1011 and the position of the rear spring buckle 1012 can be swapped, and accordingly, the position of the second front buckle 1001 and the position of the rear buckle 1002 can be swapped. The specific buckle positions and spring buckle positions are not limited in this embodiment of the application.

[0068] It is understood that in the embodiments of the present application, Figure 7 As shown, the first locking component includes a first front buckle 1011 and a rear spring buckle 1012, and the second locking component includes a second front buckle 1001 and a rear buckle 1002. When the first front buckle 1011 and the second front buckle 1001 are buckled into place, and when the rear spring buckle 1012 and the rear buckle 1002 are buckled into place, the reagent bottle 101 that has not been loaded into place is pushed into place by the guide surface 20.

[0069] Specifically, in the embodiments of the present application, Figure 2 As shown, when the first front buckle 1011 and the second front buckle 1001 are not buckled into place, and the rear spring buckle 1012 is located below the buckling position of the rear buckle 1002, the driving device is used to drive one of the correction device 2 and the reagent holder 10 to move relative to the other, so that the guide surface 20 pushes the reagent bottle 101 that is not loaded into place, so that the first front buckle 1011 drops to the buckling position of the second front buckle 1001, and then, under the elastic force of the rear spring buckle 1012, it buckles into place with the second front buckle 1001.

[0070] It should be noted that, in the embodiment of the present application, the reagent bottle 101 is not loaded into place, and its front end may be tilted, such as Figure 2 As shown, when the reagent bottle 101 that has not been loaded into place passes through the guide surface 20, the guide surface 20 will press the reagent bottle 101 downward in the vertical direction, so that the position of the first front buckle 1011 drops until the first front buckle 1011 is lower than the downward hook angle of the second front buckle 1001, that is, lower than the buckle position of the second front buckle 1001. At the same time, the guide surface 20 also generates pressure on the rear spring buckle 1012. Afterwards, as the reagent holder 10 and the correction device 2 continue to move relative to each other, the reagent bottle 101 will break away from the guide surface 20. The rear spring buckle 1012 will rebound based on the pressure of the guide surface 20 on it in the absence of downward pressure. Correspondingly, the first front buckle 1011 on the other side is pushed by its elastic force to buckle into place with the second front buckle 1001.

[0071] It should be noted that, in the embodiment of the present application, the tip of the reagent bottle 101 may be tilted. Figure 3 In the situation shown, the first front buckle 1011 is disengaged from the second front buckle 1001. At this time, the height of the reagent bottle 101 that is not loaded into place may exceed the highest point of the guide surface 20, so that the reagent bottle 101 that is not loaded into place is intercepted by the correction device 2, and the correction of the reagent bottle 101 cannot be achieved. For this scenario, the sample analyzer can actually further include a sensing device for sensing whether the reagent bottle 101 that is not loaded into place is intercepted. In addition, an alarm device can also be included. When the sensing device senses that the reagent bottle 101 that is not loaded into place is intercepted, an alarm message is output to prompt the user, and the user can manually load the reagent bottle 101 that is not loaded into place into place.

[0072] Specifically, in the embodiments of the present application, Figure 4 As shown, when the first front buckle 1011 is located below the buckle position of the second front buckle 1001 and the rear spring buckle 1012 is not buckled into place with the rear buckle 1002, the driving device is used to drive one of the correction device 2 and the reagent holder 10 to move relative to the other, so that the guide surface 20 pushes the reagent bottle 101 that is not loaded into place, so that the rear spring buckle 1012 drops to the buckle position of the rear buckle 1002 and then rebounds, and is buckled into place with the rear buckle 1002.

[0073] It should be noted that, in the embodiment of the present application, the reagent bottle 101 is not loaded into place, and its rear end may be tilted, such as Figure 4 As shown, when the reagent bottle 101 that has not been loaded into place passes through the guide surface 20, the guide surface 20 will press the reagent bottle 101 downward in the vertical direction, thereby causing the position of the rear spring buckle 1012 to drop until the rear spring buckle 1012 is lower than the downward hook angle of the rear snap buckle 1002, that is, lower than the snap position of the rear snap buckle 1002. Afterwards, as the reagent holder 10 and the correction device 2 continue to move relative to each other, the reagent bottle 101 will break away from the guide surface 20, and the rear spring buckle 1012 will rebound based on the pressure of the guide surface 20 on it without the downward pressure, thereby snapping into place with the rear snap buckle 1002.

[0074] It should be noted that, in the embodiment of the present application, the rear end of the reagent bottle 101 may be tilted. Figure 5 The situation shown is that the rear spring buckle 1012 is disengaged from the rear snap buckle 1002. During the relative movement of the reagent holder 10 and the correction device 2, the reagent bottle 101 that has not been loaded into place first contacts the second support arm 22. The rear spring buckle 1012 first abuts against the rear snap buckle 1002 under the push of the second support arm 22, and then snaps into place with the rear snap buckle 1002 under the downward pressure of the guide surface 20.

[0075] It is understood that in the embodiment of the present application, the reagent bottle 101 that is not loaded into place is loaded and corrected in the forward tilted state, so that the first front snap 1011 and the second front snap 1001 are snapped into place, and the rear snap 1012 and the rear snap 1002 are snapped into place. Similarly, the reagent bottle 101 that is not loaded into place is loaded and corrected in the backward tilted state, so that the rear snap 1012 and the rear snap 1002 are snapped into place, and the first front snap 1011 and the second front snap 1001 are snapped into place, as shown in FIG. Figure 8 shown.

[0076] It can be understood that in the embodiment of the present application, during the relative movement between the reagent seat 10 and the correction device 2, the guide surface 20 is higher than the reagent bottle loaded into place on the reagent seat 10, and will not interfere with the reagent bottle loaded into place. The reagent bottle loaded into place can pass directly from under the guide surface 20.

[0077] Specifically, in an embodiment of the present application, the sample analyzer also includes a sample carrying device, a sample dispensing device, a reagent dispensing device, a reaction device and a measuring device. The sample carrying device is used to carry samples, the sample dispensing device is used to draw samples from the sample carrying device and inject the samples into a reaction cup, the reagent dispensing device is used to draw reagents from the reagent storage device 1 and inject the reagents into the reaction cup, the reaction device provides an incubation place for the reaction liquid formed by the mixture of the sample and the reagent, and the measuring device is used to measure the reaction liquid.

[0078] It can be understood that in the embodiments of the present application, the sample analyzer is used to perform sample analysis. Therefore, it not only includes the above-mentioned reagent storage device 1, correction device 2 and driving device, but also includes a sample carrying device, a sample dispensing device, a reagent dispensing device, a reaction device and a measuring device, so that when performing the sample analysis action, the sample dispensing device realizes the extraction and injection of the sample, and the reagent dispensing device realizes the extraction and injection of the reagent, so as to provide a basis for the subsequent incubation and measurement of the reaction liquid.
