Among them, the terms "first position" and "second position" are two different positions, and the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] like Figure 1 and Figure 2As shown, this embodiment provides a sample analyzer, which includes a first carrier 110, a mixing assembly 200, a first manipulator 310, a second carrier 120 and a second manipulator 320, wherein the first carrier 110 is used to carry a reaction cup; the mixing assembly 200 includes a mixing base 230 and a mixing member 240, wherein the mixing member 240 is movably arranged on the mixing base 230, and can move between a cup receiving position 210 and a material receiving position 220, and can mix the sample and reagent in the reaction cup; the activity range of the output end of the first manipulator 310 covers the first carrier 110 and the cup receiving position 210; and is used to transfer the reaction cup between the first carrier 110 and the cup receiving position 210. The second carrier 120 is used to carry a sample; the activity range of the output end of the second manipulator 320 covers the sample material outlet position 121 and the material receiving position 220 on the second carrier 120; and is used to transfer the sample between the second carrier 120 and the material receiving position 220. The movable ranges of the output ends of the first manipulator 310 and the second manipulator 320 are independent of each other. Specifically, the mixing member 240 is slidably disposed on the mixing base 230 along the X direction. The movable ranges of the output ends of the first manipulator 310 and the second manipulator 320 are independent of each other, or it can be said that the movable ranges of the output ends of the first manipulator 310 and the second manipulator 320 do not have overlapping parts.

[0043] The above arrangement avoids collision between the first manipulator 310 and the second manipulator 320 during the process of transferring the reaction cup and the sample, avoids damage to the sample analyzer due to collision of the manipulators, and reduces maintenance costs.

[0044] In some embodiments, the sample analyzer further includes an incubation unit 400, which is used to provide an incubation temperature for the mixed solution in the reaction cup; the range of motion of the output end of the first manipulator 310 also covers the incubation unit 400. The incubation temperature can be determined according to the specific test items, which is not limited here. The incubation unit 400 is provided with a plurality of incubation positions 420, each of which can provide an incubation temperature for the mixed solution in the reaction cup.

[0045] Specifically, the range of motion of the output end of the first manipulator 310 covers the first carrier 110, the incubator 400 and the cup receiving position 210. The above arrangement enables the first manipulator 310 to move the reaction cup from the first carrier 110 to the cup receiving position 210, and then place the reaction cup carrying the sample and reagent on the incubator 400 for incubation.

[0046] The sample analyzer also includes a photometric component 500, which is provided with a photometric position 510. The photometric component 500 detects the reactant after the sample and the reagent react at the photometric position 510; the activity range of the output end of the first manipulator 310 also covers the photometric position 510. Specifically, the activity range of the output end of the first manipulator 310 covers the first carrier 110, the incubator 400, the cup receiving position 210 and the photometric position 510. The above arrangement enables the first manipulator 310 to transfer the reaction cup between the first carrier 110, the cup receiving position 210, the incubator 400 and the photometric position 510; one manipulator completes the transfer of the reaction cup between multiple parts, reducing costs and reducing the footprint of the sample analyzer. It should be noted that the method of testing the reactant at the photometric position 510 is mastered by those skilled in the art, so it will not be described in detail here.

[0047] The photometric element 500 has at least two photometric positions 510, and the output end of the first manipulator 310 covers at least one photometric position 510. The above arrangement can realize the simultaneous testing of reactants in at least two reaction cups, thereby improving the testing efficiency. In some embodiments, there are three photometric positions 510.

[0048] A heating notch 410 is provided on one side of the incubation part 400 close to the mixing component 200, and the cup receiving position 210 is located in the heating notch 410. The above arrangement reduces the extension length of the second manipulator 320 in the X direction, thereby reducing the cost; at the same time, the structure between the incubation part 400 and the mixing component 200 is more compact, thereby reducing the floor space of the sample analyzer and reducing the cost.

[0049] In some embodiments, the sample analyzer further includes a magnetic washing part 600, which has a magnetic washing position 610, and the magnetic washing part 600 washes the reactants after the sample and the reagent react at the magnetic washing position 610; the activity range of the output end of the first manipulator 310 also covers the magnetic washing position 610. Specifically, the activity range of the output end of the first manipulator 310 covers the first carrier 110, the incubation part 400, the cup receiving position 210, the photometric position 510 and the magnetic washing position 610. The above setting enables the first manipulator 310 to transfer the reaction cup between the first carrier 110, the cup receiving position 210, the incubation part 400, the photometric position 510 and the magnetic washing position 610; one manipulator completes the transfer between multiple parts, reduces costs, and reduces the footprint of the sample analyzer. It is worth noting that the magnetic washing part 600 is used to wash away impurities generated during the reaction process, and the specific washing method is well known to those skilled in the art, so it will not be repeated here.

[0050] The magnetic washing unit 600 rotates around its own axis, and a plurality of magnetic washing positions 610 are arranged on the magnetic washing unit 600 around its own axis. During the rotation of the magnetic suction unit, the magnetic washing position 610 closest to the incubation unit 400 is used to receive the reaction cup, thereby reducing the transmission distance and improving the transmission efficiency. Each magnetic washing position 610 can independently complete the cleaning of the reactants.

[0051] The photometric component 500 can rotate around its own axis so that the distance between one of the photometric positions 510 and the magnetic washing component 600 is the shortest, so that the reaction cup can be placed from one magnetic washing position 610 of the magnetic washing component 600 to the photometric position 510 closest to the magnetic washing component 600, thereby improving the transportation speed and further improving the test efficiency.

[0052] In some embodiments, the second carrier 120 includes a loading area 122 and an unloading area 123, a sample discharge position 121 is provided between the loading area 122 and the unloading area 123, and the unloading area 123 is located on the side of the loading area 122 close to the shell. The shell cover is provided on the outer periphery of the second carrier 120, and the shell is not shown in the figure. The above arrangement enables the unloading area 123 to be located on the inner side of the shell, and there is a certain space between the unloading area 123 and the shell, so that it is convenient to reach in to unload, which is convenient for the operator to operate and improves the comfort of operation.

[0053] Since the sample is carried by the sample container 126, when in use, the sample container 126 is first placed in the loading area 122, and the sample container 126 moves to the unloading area 123 after passing the sample discharge position 121. Among them, the loading area 122 can accommodate multiple sample containers 126, and the multiple sample containers 126 are arranged in parallel in the loading area 122 along the Y direction. When in use, the sample container 126 inside the loading area 122 moves to the unloading area 123 after passing the sample discharge position 121. The sample container 126 that takes out the sample moves to the unloading area 123, and gradually moves outward under the push of the subsequent sample container 126. When there are only one or two sample containers 126, after the sample is used up, the sample container 126 is located in the unloading area 123, which is located away from the operator. Among them, a transfer line 125 is set between the loading area 122 and the unloading area 123, and the sample container 126 moves from the loading area 122 to the unloading area 123 under the transmission action of the transfer line 125. Among them, the transfer line 125 can be an assembly line, and the specific structure is well known to those skilled in the art, so it will not be described here.

[0054] Furthermore, the housing is provided with an outwardly concave escape portion near the unloading area 123. The escape portion makes the operating space larger and further improves the comfort of the operator.

[0055] The second carrier 120 further includes an emergency channel 124, one end of which is located at the sample discharge position 121. The emergency channel 124 is used to transport emergency samples to the sample discharge position 121, thereby saving the operation of placing the sample in the loading area 122, improving the sample transmission efficiency, and meeting the more urgent requirements for sample testing during the emergency process. The emergency channel 124 is located between the loading area 122 and the unloading area 123.

[0056] In some embodiments, the sample analyzer further includes a third carrier 130 and a cleaning member 700. The third carrier 130 is used to carry reagents and has a reagent discharge position. The cleaning member 700 is used to clean the needle. The activity range of the output end of the second manipulator 320 also covers the cleaning member 700 and the reagent discharge position. The above configuration enables the activity range of the output end of the second manipulator 320 to cover the sample discharge position 121, the material receiving position 220, the cleaning member 700 and the reagent discharge position. The filling of samples and reagents is completed by a second manipulator 320, and the cleaning member 700 is used to clean the filled needle during the interval of filling to avoid contamination. At the same time, one manipulator completes the filling of samples and reagents, reducing costs and reducing the footprint of the sample analyzer. The third carrier 130 is provided with a plurality of bearing positions, which are arranged in three rings. The third carrier 130 is provided with three reagent discharge positions, which are respectively defined as a first reagent discharge position 131, a second reagent discharge position 132 and a third reagent discharge position 133, wherein the three ring-shaped bearing positions correspond to the three reagent discharge positions. Of course, the bearing positions can also be arranged in four or even ten ring structures.

[0057] Before testing the reactants after the reaction of the sample and the reagent, a diluent needs to be added to the reactants. Therefore, the sample analyzer also includes a dilution barrel for storing the dilution barrel to complete the addition of the dilution barrel at any time.

[0058] During a normal test, the diluent may run out, and the dilution barrel needs to be replaced. Therefore, the machine needs to be shut down to complete the replacement of the dilution barrel, resulting in reduced test efficiency.

[0059] To solve the above problems, in some embodiments, the sample analyzer further includes a buffer barrel 800, which is used to buffer the diluent. The buffer barrel 800 is connected to the dilution barrel. The setting of the buffer barrel 800 can buffer the diluent to a certain extent, so that when the dilution barrel is replaced, the diluent buffered in the buffer barrel 800 meets the working requirements of the preset time length without stopping the machine, which is conducive to ensuring the test efficiency.

[0060] The first manipulator 310 includes a first base 311, a first arm 312, a second arm, a third arm and a first gripper; the first arm 312 is slidably disposed on the first base 311 along the Y direction, the second arm is slidably disposed on the first arm 312 along the X direction, the third arm is slidably disposed on the second arm along the vertical direction, and the first gripper is disposed at the lower end of the third arm. The first gripper can grab a reaction cup.

[0061] The X direction is the left-right direction, the Y direction is the front-back direction, and the vertical direction is the up-down direction.

[0062] The second manipulator 320 includes a second base, a swing arm and a lifting arm, one end of the swing arm is rotatably arranged on the second base, the lifting arm is slidably arranged on the other end of the swing arm in a vertical direction, and the needle is arranged at the lower end of the lifting arm. When in use, the swing arm is swung so that the needle is aligned with the three reagent discharge positions respectively.

[0063] It should be noted that the first carrier 110, the incubation part 400, and the photometric part 500 are spaced apart in the Y direction; the magnetic washing part 600 and the photometric part 500 are spaced apart in the X direction. The magnetic washing part 600 is located on the right side of the photometric part 500. In other words, the magnetic washing part 600 is located on the side of the photometric part 500 close to the third carrier 130. The material receiving position 220, the sample discharge position 121, the reagent discharge position and the cleaning part 700 are all located on the swing track 321 of the second gripper. Among them, the second carrier 120 and the first carrier 110 are spaced apart in the X direction; the second carrier 120 and the third carrier 130 are spaced apart in the Y direction. The above position arrangement makes the entire sample analyzer compact in structure, occupies a small area, and reduces costs.

[0064] The following is a brief description of the workflow: the first manipulator 310 moves the reaction cup from the first carrier 110 to the mixing part 240 at the cup receiving position 210, and the mixing part 240 moves to the material receiving position 220; the second manipulator 320 extracts the reagent from the sample discharge position 121 through a needle, and injects it into the reaction cup at the material receiving position 220; the second manipulator 320 moves the needle to the cleaning part 700 for cleaning, and moves the needle to the reagent discharge position to extract the reagent, and moves to the material receiving position 220 again to inject the reagent into the reaction cup; the mixing part 240 moves to the cup receiving position 210, and the first manipulator 310 moves the reaction cup to the incubation part 400. After the incubation is completed, the first manipulator 310 moves the reaction cup to the magnetic washing part 600. After the cleaning is completed, the first manipulator 310 moves the reaction cup to the light measuring part 500 for testing.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
