And simultaneously, the embodiment of the utility model provides an among the sample analyzer, filling module 400 is arranged in to the reaction cup A at mixing position 502 with sample and reagent filling, directly at mixing position 502 filling reagent and sample, has also shortened filling module 400's stroke, has reduced the required removal space of filling module 400, has improved the compactedness of complete machine structure, has reduced the area of complete machine, has also reduced the cost.

In the sample analyzer, since the grabbing module 200 needs to move the cuvette in the pick-and-place cup position 501 to the reaction detection system, the pick-and-place cup position 501 can be selected to be closer to the reaction detection system than the mixing position 502, so that the stroke of the grabbing module 200 can be further shortened.

In order to facilitate the grasping module 200 to grasp and release the cuvette a, the grasping module 200, the reaction detecting system and the cuvette loading module 100 may be selected to be located on the same side of the cup placing and placing position 501. It is understood that the grasping module 200, the reaction detecting system and the reaction cup loading module 100 are all located at one side of the picking and placing cup position 501, and the reagent storing module 900 is located at the other side of the picking and placing cup position 501.

In practical application, other layouts can be selected and are not limited to the above embodiments.

In the actual use process, when two reagents need to be filled, the reaction cup a in the reaction detection system needs to be moved to the cup placing position 501. To facilitate the above operations, the reaction cup loading module 100 may be located at one side of the reaction detection system, and the reaction detection system is closer to the cup picking and placing position 501 than the reaction cup loading module 100.

Of course, the reaction cup loading module 100 may be closer to the cup picking and placing position 501 than the reaction detection system, and is not limited to the above embodiments.

In the sample analyzer, the reaction detection system is selected according to actual needs. Specifically, the reaction detection system includes: the kit comprises a reaction module 600, a magnetic separation module 800 and a detection module 700, wherein the reaction module 600 is used for enabling a sample and a reagent in a reaction cup A to react, the magnetic separation module 800 is used for extracting a target object in the reaction cup A, and the detection module 700 is used for detecting the target object in the reaction cup A; at this time, the grasping module 200 is used for moving the cuvette a in the cup placing/placing position 501 to the reaction module 600, for moving the cuvette a in the reaction module 600 to the magnetic separation module 800, and for moving the cuvette a in the magnetic separation module 800 to the detection module 700.

Since the reaction cup a needs to pass through the reaction module 600, the magnetic separation module 800 and the detection module 700 in sequence, the reaction module 600 and the magnetic separation module 800 can be selected to be closer to the cup taking and placing position 501 than the detection module 700 in order to grasp the stroke of the module 200.

In an actual application process, the distances from the reaction module 600, the detection module 700, and the magnetic separation module 800 to the cup position 501 may be equal or distributed in other manners, which is not limited in this embodiment.

In the sample analysis process, one or two reagents may be required. If two reagents are needed, the two reagents are respectively a first reagent and a second reagent, two times of blending needs to be performed, that is, two blending positions 502 and two blending modules need to be used. In a sample processing time, a long time is needed to process the next sample after the first reagent is mixed uniformly, a long time is needed to process the next sample after the second reagent is mixed uniformly, and the mixing module is in an idle state in the waiting time. In order to reduce the number of the blending stations 502 and the blending modules to save cost, the same blending module may be used to blend the first reagent and the second reagent, and specifically, the blending of the second reagent may be completed within the waiting time. Specifically, the grasping module 200 is further configured to move the cuvette a that has been extracted by the magnetic separation module 800 to the cup taking and placing position 501, and the filling module 400 is configured to fill the sample and the first reagent into the cuvette a at the mixing position 502 and fill the second reagent into the cuvette a at the mixing position 502 and passing through the magnetic separation module 800.

In the sample analyzer, after the sample and the first reagent are added at the mixing position 502, mixing can be started, and the sample and the first reagent can be added and mixed uniformly; after the mixing, the transfer module 500 moves the reaction cup a to the picking and placing cup position 501, the grabbing module 200 grabs the reaction cup a filled with the sample and the first reagent into the reaction module 600, at this time, the grabbing module 200 can place the cleaned reaction cup a in the magnetic separation module 800 into the placing structure of the picking and placing cup position 501, the transfer module 500 moves the reaction cup a to the mixing position 502, the second reagent is filled and mixed uniformly, and the filling and mixing of the second reagent are completed; after the mixture is completely mixed, the transferring module 500 moves the cuvette a to the cup placing position 501, and the grabbing module 200 grabs the cuvette a filled with the sample and the second reagent out to the reaction module 600.

Specifically, the transfer module 500 further comprises a turntable, the placing structure is arranged on the turntable, and the transfer driving device drives the turntable to rotate around the axis of the turntable.

In order to shorten the distance between the blending position 502 and the cup taking and placing position 501, the blending position 502 and the cup taking and placing position 501 can be symmetrically arranged around the axis of the turntable.

To facilitate movement of the gripper 202 within the gripping area 201, the gripper drive mechanism may be selected to drive the gripper 202 in an X-direction, a Y-direction, and a Z-direction, wherein the X-direction, the Y-direction, and the Z-direction are perpendicular to each other. Further, the gripper driving mechanism can drive the gripper 202 to move in the X-direction, the Y-direction, and the Z-direction at the same time. Thus, the exercise time can be saved and the efficiency can be improved.

One or more than two hand grips 202 may be provided. To simplify the structure, reduce the volume, and reduce the cost, the hand grip 202 may be selected as one. At this time, the gripping area 201 is a gripping range of one gripper 202. Therefore, the movement stroke of the hand grip 202 is reduced, and the space of the whole machine is saved.

Specifically, there are two clamping jaws 202a, when a reaction cup a exists between the two clamping jaws 202a, the two clamping jaws 202a cannot be completely closed, and at this time, the photoelectric blocking piece 202c cannot enter the notch of the photoelectric switch 202b, and it is determined that the reaction cup a is clamped or the gripper 202 is in an open state; without cuvette a, the two jaws 202a may be completely closed, and the photoelectric barrier 202c may enter the notch of the photoelectric switch 202b, and it is determined that there is no cuvette a between the two jaws 202a or that the two jaws 202a are in a closed state. Whether the grabbing of the reaction cup A is successful or not can be judged by moving the hand grab 202 to the corresponding position, so that whether the reaction cup A is in the position or not can be judged, and the reaction cup detection devices in the reaction cup loading module 100, the detection module 700, the reaction module 600, the magnetic separation module 800 and the transfer module 500 can be eliminated, so that the structure is simplified, and the cost is reduced.
