[0011] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] The sample loading plate unit 100 includes a sample loading plate 110, which has a plurality of sample cup holder structures 111 for supporting reaction cups. The sample loading plate 110 can rotate about a vertically extending rotation axis so that the sample cup holder structures 111 can sequentially pass through the sample loading operation position 101 and at least one drain position 102. Each sample cup holder structure 111 is spaced apart and surrounds the rotation axis of the sample loading plate 110.
[0017] The sample addition unit 200 is used to add samples to the reaction cup located at the first liquid level 102. In a specific embodiment of the invention, preferably, the sample addition unit includes a sampling needle, a sampling needle driving mechanism, and a sampling needle cleaning mechanism. The specific operation flow of the sample addition unit is as follows: the sampling needle driving mechanism drives the sampling needle from the sampling needle cleaning mechanism to above the sample tube on the sample holder. Then, the sampling needle moves vertically downwards into the sample tube to draw a certain amount of sample. Subsequently, the sampling needle moves vertically upwards to the reaction cup located at the liquid level 102, discharging a certain amount of sample. Finally, the sampling needle moves vertically upwards and is withdrawn from the reaction cup. At this time, the sampling needle driving mechanism drives the sampling needle to the sampling needle cleaning mechanism to clean the inner and outer walls of the sampling needle. The sampling needle driving mechanism can adopt a rotary rocker arm driving structure or a linear guide rail driving structure.
[0018] The reagent adding unit 300 is used to add reagents to the reaction cup located at the first liquid level 102. In a specific embodiment of the present invention, preferably, the reagent adding unit 300 includes a reagent needle, a reagent needle driving mechanism, and a reagent needle cleaning mechanism. The specific operation flow of the reagent adding unit 300 is as follows: the reagent needle driving mechanism drives the reagent needle from the reagent needle cleaning mechanism to the reagent supply unit, then the reagent needle moves vertically downwards into the reagent supply unit to draw a certain amount of sample. Subsequently, the reagent needle moves vertically upwards to the reaction cup, discharging a certain amount of reagent. Finally, the reagent needle moves vertically upwards and is withdrawn from the reaction cup. At this time, the reagent needle driving mechanism drives the reagent needle to the reagent needle cleaning mechanism to... The inner and outer walls of the reagent needle are cleaned. It should be noted that if the reagent to be aspirated by the reagent addition unit 300 next time is the same reagent, cleaning is not required. It should also be noted that the sample addition position of the sample addition unit 200 and the reagent addition position of the reagent addition unit 300 can be at the same discharge position, in which case the sample addition unit 200 and the reagent addition unit 300 can alternately operate on the same reaction cup, or they can be at different discharge positions, in which case the sample addition unit 200 and the reagent addition unit 300 can operate on two different reaction cups simultaneously, which can improve the efficiency of operation.
[0019] The reaction unit 400 is used to incubate reaction cups and includes multiple incubation cup structures arranged in an array to support the reaction cups. It should be noted that in this embodiment, the incubation cup structures are arranged in a rectangular array, while in other embodiments, the incubation cup structures can also be arranged in a ring, and multiple rings with different radii can be arranged. In this case, the reaction unit 400 can be a disc-shaped structure. Specifically, the reaction unit 400 provides a constant-temperature reaction environment for the sample and reagent reaction solution.
[0020] The cleaning unit 500 is used to clean away unreacted samples and reagents in the reaction vessel. It should be noted that after cleaning away unreacted samples and reagents in the reaction vessel, the cleaning unit 500 can be used to inject luminescent substrate solution into the reaction vessel as needed.
[0021] The photometric unit 600 includes a first photometric optical disc 610, a second photometric optical disc 620, and a photometer 640. The first photometric optical disc 610 has at least one first photometric cup support structure 611 for supporting the reaction cup. The first photometric optical disc 610 can rotate about a vertically extending rotation axis to allow the first photometric cup support structure 611 to sequentially pass through a first pre-photometric operation position 6101, a first post-photometric operation position 6102, and a photometric position 6103. The second photometric optical disc 620 has at least one second photometric cup support structure 621 for supporting the reaction cup. The second photometric optical disc 620 can rotate about a rotation axis to allow the second photometric cup support structure 621 to sequentially pass through a second photometric inlet position 6201 and a second photometric outlet position 6202. The photometer 640 is used to measure the light intensity of the reaction cup at the photometric position 6103. The photometer 640 can convert the measured light intensity into a digital signal output, thus facilitating signal reception and reducing signal conversion.
[0022] The reaction transfer unit 700 includes a first transfer gripper 710 and a second transfer gripper 720. The first transfer gripper 710 is capable of transferring the reaction cup from the container supply position to the sample dispensing position 101, from the sample dispensing position 101 to the first pre-measuring position 6101, from the first pre-measuring position 6101 to the cup-discarding position 7101, and from the second measuring cup-out position 6202 to the sample dispensing position 101. The second transfer gripper 720 is capable of transferring the reaction cup from the first post-measuring position 6102 to the reaction unit 400, from the reaction unit 400 to the first post-measuring position 6102, from the reaction unit 400 or the cleaning unit 500 to the second measuring cup-in position 6201, and from the reaction unit 400 to the cleaning unit 500. In this embodiment of the invention, preferably, the first transfer gripper is a two-dimensional motion gripper, and the second transfer gripper is a three-dimensional motion gripper.
[0023] Of course, it should be noted that in the specific implementation of the present invention, the automatic analysis device will also include a control unit, which is used to control the operation and timing of the sample loading plate unit 100, sample loading unit 200, reagent addition unit 300, reaction unit 400, cleaning unit 500, photometric unit 600, and reaction cup transfer unit.
[0024] Based on the structural design of this invention, such as Figure 3 As shown, the automatic analysis steps for implementing the one-step test are as follows: One-step reagent addition: The sample addition plate 110 rotates, causing the sample addition cup structure 111 to pass through the sample addition operation position 101 and each liquid discharge position 102 in sequence. Among them, the sample addition unit 200 adds the sample to the reaction cup, and the reagent addition unit 300 adds the reagent to the reaction cup.
[0025] This step involves adding the sample and reagents, and forming the reaction solution.
[0026] One-step reagent incubation: The sample loading tray 110 rotates, driving the sample loading cup structure 111 to the sample loading operation position 101. The first transfer gripper 710 moves the reaction cup from the sample loading operation position 101 to the first pre-measuring operation position 6101. The first measuring disc 610 rotates, and the reaction cup moves with the first measuring cup structure 611 from the first pre-measuring operation position 6101 to the first post-measuring operation position 6102. The second transfer gripper 720 transfers the reaction cup from the first post-measuring operation position 6102 to the reaction unit 400.
[0027] In this step, the reaction unit 400 incubates the reaction solution in the reaction vessel.
[0028] Cleaning and separation: The second transfer gripper 720 transfers the reaction vessel from the reaction unit 400 to the cleaning unit 500, where the cleaning unit 500 cleans away any unreacted sample and reagents from the reaction vessel.
[0029] Light intensity measurement: The second transfer gripper 720 transfers the reaction cup from the reaction unit 400 to the first photometer post-operation position 6102. The first photometer disc 610 rotates and moves the reaction cup from the first photometer post-operation position 6102 to the photometer position 6103. The photometer 640 measures the light intensity of the reaction cup located at the photometer position 6103.
[0030] Discarding the cup: The first photometric disc 610 rotates, and the reaction cup moves from the photometric position 6103 to the first photometric pre-operation position 6101 along with the first photometric cup support structure 611. The first transfer gripper 710 moves the reaction cup from the first photometric pre-operation position 6101 to the cup-discarding position 7101 to perform cup-discarding.
[0031] Compared to one-step testing, to achieve automated analysis of two-step testing, such as... Figure 4 As shown, the process between cleaning separation and light intensity measurement also includes: Return and transfer: The second transfer gripper 720 transfers the reaction cup from the cleaning unit 500 to the second photometric inlet position 6201. The second photometric disc 620 rotates, and the reaction cup moves from the second photometric inlet position 6201 to the second photometric outlet position 6202 along with the second photometric cup holder structure 621. The first transfer gripper 710 rotates the reaction cup from the second photometric outlet position 6202 to the sample loading operation position 101.
[0032] Two-step reagent addition: The sample addition plate 110 rotates, causing the sample addition cup structure 111 to pass through the sample addition operation position 101 and each drainage position 102 in sequence. The reagent addition unit 300 adds reagent to the reaction cup located at the drainage position 103.
[0033] Two-step reagent incubation: The first transfer gripper 710 moves the reaction cup from the sample addition operation position 101 to the first pre-photometric operation position 6101. The first photometric disc 610 rotates, and the reaction cup moves from the first pre-photometric operation position 6101 to the first post-photometric operation position 6102 along with the first photometric cup holder structure 611. The second transfer gripper 720 transfers the reaction cup from the first post-photometric operation position 6102 to the reaction unit 400.
[0034] Secondary cleaning and separation: The second transfer gripper 720 transfers the reaction vessel from the reaction unit 400 to the cleaning unit 500, where the cleaning unit 500 cleans away any unreacted sample and reagents from the reaction vessel.
[0035] In other embodiments, the process may further include: between the one-step reagent incubation and washing separation. Return and transfer: The second transfer gripper 720 transfers the reaction cup from the reaction unit 400 to the second photometric inlet position 6201. The second photometric disc 620 rotates, and the reaction cup moves from the second photometric inlet position 6201 to the second photometric outlet position 6202 along with the second photometric cup holder structure 621. The first transfer gripper 710 rotates the reaction cup from the second photometric outlet position 6202 to the sample loading operation position 101.
[0036] Two-step reagent addition: The sample loading plate 110 rotates, causing the sample loading cup structure 111 to pass sequentially through the sample loading operation position 101 and the liquid discharge position 102, wherein the reagent addition unit 300 adds reagents to the reaction cup.
[0037] Two-step reagent incubation: The first transfer gripper 710 moves the reaction cup from the sample addition operation position 101 to the first pre-photometric operation position 6101. The first photometric disc 610 rotates, and the reaction cup moves from the first pre-photometric operation position 6101 to the first post-photometric operation position 6102 along with the first photometric cup holder structure 611. The second transfer gripper 720 transfers the reaction cup from the first post-photometric operation position 6102 to the reaction unit 400.
[0038] Secondary cleaning and separation: The second transfer gripper 720 transfers the reaction vessel from the reaction unit 400 to the cleaning unit 500, where the cleaning unit 500 cleans away any unreacted sample and reagents from the reaction vessel.
[0039] If pretreatment is required, it also includes the following steps before adding reagents in the first step: Pretreatment: The second transfer gripper 720 transfers the reaction cup containing the pretreatment liquid from the reaction unit 400 to the second photometric inlet 6201. The second photometric disc 620 rotates, and the reaction cup moves from the second photometric inlet 6201 to the second photometric outlet 6202 along with the second photometric cup holder structure 621. The first transfer gripper 710 rotates the pretreated reaction cup from the second photometric outlet 6202 to the sample loading operation position 101.
[0040] It should be noted that the pretreatment solution in the reaction vessel can be obtained by referring to the one-step reagent addition and one-step reagent incubation procedures.
[0041] As can be seen from the above, based on the present invention, firstly, by scheduling around the sample loading plate 110, the first test optical plate 610 and the second test optical plate 620, the time for scheduling the reaction cups is shortened, the testing speed of the automatic analysis device is improved, that is, the testing throughput is increased, and the transfer structure is simplified, making the size of the automatic analysis device more compact and reducing costs. Secondly, in the reaction unit 400, each incubation cup structure is arranged in an array, making the structure of the reaction unit 400 simpler and more compact.
[0042] Furthermore, based on this invention, various different testing procedures can be performed to meet a variety of different testing needs.
[0043] In this embodiment of the invention, the sample addition unit 200 can also draw samples from any of the drain positions 102.
[0044] Based on this, dilution operations can be performed, specifically by adding the following steps between the one-step reagent addition and the one-step reagent incubation: Diluted sample aspiration: The sample loading tray 110 continues to rotate, and the reaction cup moves from the sample loading operation position 101 to a row of liquid levels 102 along with the sample loading cup structure 111. The sample loading unit 200 aspirates the sample from the reaction cup.
[0045] Diluted sample addition: The sample addition plate 110 continues to rotate, the new reaction cup passes through each liquid level 102, the sample addition unit 200 adds the sample to the reaction cup, and the reagent addition unit 300 adds the reagent to the reaction cup.
[0046] In this embodiment of the invention, the cup-throwing position 7101 is located between the photometer unit 600 and the sample loading plate 110. Thus, the first transfer gripper 710 can throw the cup on the motion trajectory between the photometer unit 600 and the reaction unit 400, thereby simplifying the structure of the first transfer gripper 710.
[0047] In this embodiment of the invention, the photometer unit 600 is located between the reaction unit 500 and the sample loading plate unit 100. This reduces the distance from the reaction unit 500 and the sample loading plate unit 100 to the photometer unit 600, thereby reducing the working range required by the first transfer gripper 710 and the second transfer gripper 720, and thus simplifying the structure of the first transfer gripper 710 and the second transfer gripper 720.
[0048] In this embodiment of the invention, to ensure a continuous supply of samples, the automatic analysis device further includes a sample supply unit for carrying and transporting samples to be tested. In this embodiment, the sample supply unit includes a sample placement area, a sample transfer area, and a sample recovery area. The sample transfer area has at least one sample transfer channel. The sample supply unit also includes a sample rack and a scheduling mechanism. At least one sample rack is provided and is used to support at least one reaction cup. The scheduling mechanism can move the sample rack from the sample placement area to any sample transfer channel and can also move the sample rack from any sample transfer channel to the sample recovery area. The sample dispensing unit 200 can also pick up samples from the sample transfer area. Further, the sample transfer area has three sample transfer channels, and the sample dispensing unit 200 can pick up samples from at least two of them, thus better ensuring a continuous supply of samples. Even further, the sample supply unit also includes an emergency sample placement area. The scheduling mechanism can preferentially move the sample rack from the emergency sample placement area to the sample transfer area. Thus, during use, when a sample rack to be tested is detected in the emergency sample placement area, the samples in the emergency sample placement area are tested preferentially.
[0049] In this embodiment of the invention, the cleaning unit 500 includes a magnetic separation disk, a liquid injection mechanism, a liquid suction mechanism, a mixing structure, and a magnetic adsorption mechanism.
[0050] In this embodiment of the invention, the rotation axes of the first measuring optical disc 610 and the second measuring optical disc 620 are coaxially arranged and rotate synchronously; the first measuring cup structure 611 and the second measuring cup structure 621 are moved in pairs to the first pre-measuring operation position 6101 and the second measuring cup exit position 6202, respectively. Thus, the first measuring optical disc 610 and the second measuring optical disc 620 can share a single driving structure, which simplifies the structure of the measuring unit 600.
[0051] It should be noted that, in conjunction with the present invention, the first transfer gripper 710 is a two-dimensional motion gripper, and the first photometric cup structure 611 and the second photometric cup structure 621 are arranged in pairs below the movement path of the first transfer gripper 710.
[0052] In other embodiments of the present invention, the rotation axes of the first measuring optical disc 610 and the second measuring optical disc 620 are coaxially arranged and rotate independently of each other; that is, the first measuring optical disc 610 and the second measuring optical disc 620 are driven by their respective driving structures. Thus, the first measuring optical disc 610 and the second measuring optical disc 620 can rotate independently according to actual needs.
[0053] In this embodiment of the invention, the sample loading plate unit 100 further includes a mixing mechanism; When the sample loading plate 110 rotates around a vertically extending rotation axis, it can drive the sample loading cup structure 111 to pass through the sample loading operation position 101, each liquid discharge position 102 and the mixing position 104 in sequence. The mixing mechanism shakes and mixes the reaction vessel at mixing position 104.
[0054] Based on this, during the process of the sample loading plate 110 moving the sample loading cup structure from the liquid discharge position to the sample loading operation position, it will pass through the mixing position. The mixing mechanism shakes and mixes the reaction cup, which helps to make the sample evenly distributed in the reagent.
[0055] Specifically, in this embodiment of the invention, when the mixing mechanism needs to perform mixing, it needs to cooperate with the bottom of the reaction cup to shake the bottom of the reaction cup. Therefore, when the mixing mechanism needs to perform mixing, it can either move the sample loading plate downwards and reset after mixing, or move the mixing mechanism upwards and reset after mixing. The upward movement of the mixing mechanism helps to simplify the overall structural complexity of the automatic analysis device. The mixing mechanism adopts a non-contact vortex eccentric oscillation method or an ultrasonic mixing method. The mixing mechanism has vertical up-and-down movement. When mixing is required, the mixing mechanism moves vertically upwards, dropping a part of the reaction cup into the mixing mechanism to start mixing the reaction liquid. After mixing for a period of time, the mixing mechanism moves vertically downwards and returns to the initial position.
[0056] In this embodiment of the invention, the photometric unit 600 further includes a waste liquid absorption mechanism 630; When the first optical measuring disc 610 rotates around a vertically extending rotation axis, it can drive the first optical measuring cup structure 611 to pass sequentially through the first optical measuring pre-operation position 6101, the first optical measuring post-operation position 6102, the optical measuring position 6103, and the waste liquid suction position 6104. Waste liquid absorption mechanism 630 is used to draw waste liquid from the reaction cup at waste liquid level 6104.
[0057] Based on this, the waste liquid in the reaction cup is absorbed by the waste liquid absorption mechanism 630 to increase the sample concentration and facilitate the measurement by the photometer 640.
[0058] In this embodiment of the invention, the photometric unit 600 further includes an excitation liquid injection mechanism, which is used to inject excitation liquid into the reaction cup before the photometer 640 measures the light intensity of the reaction cup. Thus, for some samples that require the addition of excitation liquid to emit light, adding excitation liquid before photometric measurement stimulates the reaction liquid to emit a certain light intensity, facilitating measurement by the photometer 640, thereby increasing the types of samples that the automatic analysis device can analyze.
[0059] In this embodiment of the invention, the sample cup structure 111 is a through hole that runs vertically through the reaction cup and prevents the reaction cup from falling.
[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
