Through the multi-station proportioning component provided in this application and each rotatable micro syringe 9 fixed on the annular plate 4, multi-station proportioning can be provided, and the concentration of the finished reagent after each proportioning can be adjusted according to needs, which is convenient for use.

[0027] In this embodiment, the multi-station proportioning component specifically includes: a strip-shaped groove 16 opened in the middle position of the top surface of the strip-shaped support plate 15. A linear guide rail 17 is fixedly connected to the bottom end surface of the strip-shaped groove 16, and two juxtaposed linear motors 18 are movably connected to the top end of the linear guide rail 17. A strip-shaped placing plate 19 is fixedly connected to the top ends of the two linear motors 18, and a plurality of uniformly distributed card slots 21 are opened along the length direction of the top surface of the strip-shaped placing plate 19. A transparent container 22 matching the card slot 21 is arranged inside the card slot 21, and a telescopic motor 39 is embedded in the bottom end surface of the card slot 21. The multi-station proportioning component of this application juxtaposes a plurality of transparent containers 22 receiving reagent proportioning together, and sends out one transparent container 22 after one proportioning is completed, effectively improving the proportioning efficiency. In addition, after all the transparent containers 22 are proportioned, it is also convenient for the staff to compare and observe them.

At least four uniformly distributed telescopic limiting members are provided at the bottom opening position of the lid placing groove 24, and the telescopic limiting members limit the lowermost lid body 25. An inlet 26 communicating with the lid placing groove 24 is provided above one side surface of the lid placing box 23. By providing the lid placing assembly, a dust-proof lid body 25 can be placed on the top of the transparent container 22 when the transparent container 22 completes the proportioning and is sent out of the rectangular groove 14, thereby preventing external dust and impurities from entering the transparent container 22 and contaminating the reagent inside it.

A limiting block 30 matching with the notch 29 is movably connected inside the notch 29, and the cross section of the limiting block 30 is trapezoidal. A spring column 31 is fixedly connected inside the notch 29, and one end of the spring column 31 is fixedly connected with the corresponding limiting block 30. The setting of the telescopic limiting member can limit the lid body 25 and prevent the lid body 25 from easily falling out of the lid placing groove 24.

[0031] In this embodiment, the mobile observation assembly specifically includes: a concave plate 32 located below the lid placing box 23. The strip-shaped support plate 15 passes through the groove of the concave plate 32, and a magnifying glass 33 is embedded on one inner wall of the groove of the concave plate 32, and a supplementary light 34 is embedded on the other inner wall of the groove of the concave plate 32. At the lower parts of the two inner walls of the groove of the concave plate 32, rollers 36 are symmetrically and movably connected. Strip-shaped rail grooves 37 are provided at the positions corresponding to the rollers 36 on both side surfaces of the strip-shaped support plate 15, and the rollers 36 are movably connected inside the strip-shaped rail grooves 37. In this application, by providing the mobile observation assembly, it is convenient for the staff to observe the reagent products in each transparent container 22 more clearly in the subsequent comparison. Moreover, the mobile observation assembly can adjust its position according to needs, which is more convenient to use.

[0032] In this embodiment, at least three uniformly distributed movable second balls 35 are embedded on both sides of the bottom end surface of the groove of the concave plate 32, and the second balls 35 are in contact with the strip-shaped support plate 15. The setting of the second balls 35 can reduce the frictional resistance between the concave plate 32 and the strip-shaped support plate 15.

[0033] In this embodiment, the driving mechanism specifically includes: at least six driving grooves 5 opened at the edge of one side surface of the disc body 3. A driving gear 6 is rotatably connected inside the driving groove 5, and the driving gears 6 are all driven by stepping motors. Four of the stepping motors are fixed on the other side surface of the disc body 3, and the other two stepping motors are embedded inside the column 2. Tooth teeth 7 meshing with the driving gears 6 are fixedly connected to the inner side surface of the annular plate 4, and a limiting member is provided between the annular plate 4 and the column 2. The driving mechanism can drive the annular plate 4 to rotate according to a preset program, and then rotate the required micro syringe 9 to directly above the target transparent container 22 to complete reagent addition, without manual preparation, and has a high degree of automation.

[0034] In this embodiment, the limiting member specifically includes: two limiting plates 10 symmetrically arranged at the top and bottom of the annular plate 4. The limiting plates 10 are fixedly connected to the column 2. Arc-shaped grooves 11 matching the annular plate 4 are opened on the opposite surfaces of the two limiting plates 10, and an annular sliding groove 13 is opened at the edge position of one side surface of the annular plate 4 facing the column 2. An arc-shaped sliding rail 12 matching the annular sliding groove 13 is fixedly connected to the position on one side surface of the column 2 corresponding to the annular sliding groove 13, and the arc-shaped sliding rail 12 is movably connected to the annular sliding groove 13. The setting of the limiting member can effectively improve the stability of the rotation of the annular plate 4.

[0035] In this embodiment, a camera 38 is fixedly connected to the side surface of the fixing seat 8 facing the rectangular groove 14. The camera 38 can collect images and send them to the background control terminal for image analysis to judge whether there is an abnormality. It can not only analyze and judge the cleaning condition inside the lower target transparent container 22 before reagent preparation, but also analyze in real time whether there is an abnormality during reagent injection.

[0036] The working principle of the present invention is: The reagent preparation device before blood drug concentration detection in the initial state is as Figure 1As shown, the transparent container 22 closest to the rectangular groove 14 is just located below the uppermost micro syringe 9. It should be noted that different reagents are stored in each micro syringe 9, and the micro syringe 9 can control the reagent output according to a preset program. Subsequently, reagent proportioning is carried out in the first transparent container 22. During the proportioning process, whenever it is necessary to switch the micro syringe 9, the driving mechanism operates to drive the annular plate 4 to rotate, thereby rotating the required micro syringe 9 to directly above the target transparent container 22 to complete reagent addition. There is no need for manual preparation, and the degree of automation is high. Among them, the specific process of the rotation of the annular plate 4 is that the stepping motor operates to drive the driving gear 6 in the driving groove 5 to rotate. Since the driving gear 6 meshes with the teeth 7 on the inner ring of the annular plate 4, the annular plate 4 also rotates as the driving gear 6 rotates. During the process, the relative displacement between the annular sliding groove 13 and the arc-shaped sliding rail 12 improves stability, and the arc-shaped groove 11 of the limiting plate 10 further restricts the rotation of the annular plate 4 to prevent it from shifting. It should be noted that a camera 38 is fixedly connected to one side of the fixed seat 8 facing the rectangular groove 14. The camera 38 collects and analyzes the internal image of the transparent container 22 before the reagent is injected into the transparent container 22 to determine whether there are contaminants inside the transparent container 22. At the same time, it can also collect the injection image in real time during the reagent injection process to analyze whether there are abnormal phenomena such as deviation of the injection position, splashing of the reagent, and damage to the transparent container 22. Before each injection, the state of the transparent container 22 can be known through image analysis, as well as whether there was an injection deviation during the previous injection, resulting in the reagent remaining outside the transparent container 22 without entering the inside after deviation. If problems such as deviation are found, the transparent container 22 can be taken out in time and the proportioning operation can be paused.

[0037] After the first transparent container 22 completes the reagent proportioning, the multi-station proportioning assembly operates to send the second transparent container 22 to the reagent proportioning station for actual proportioning of different concentrations. Specifically, the linear motor 18 moves a certain distance along the linear guide rail 17 according to a preset program. At this time, the second transparent container 22 reaches below the uppermost micro syringe 9, and then the second round of reagent proportioning begins, and so on, until the reagent proportioning of all transparent containers 22 is completed, and finally several finished reagents with different concentration proportions are obtained for the staff to observe and select.

[0038] It should be noted that the lid placing assembly can place a dust-proof lid 25 on the top of the transparent container 22 when the transparent container 22 completes the proportioning and is sent out of the rectangular groove 14, thereby preventing external dust and impurities from entering the transparent container 22 and contaminating the reagents inside. The specific process is as follows: When the target transparent container 22 reaches below the lid placing box 23, the telescopic motor 39 at the bottom of the target transparent container 22 runs to extend the output shaft to push the target transparent container 22 upward and complete the docking with the opening below the lid placing groove 24. At the same time, the cylinder 27 runs according to the preset program to extend the output shaft to drive the pressing block 28 to move downward. The pressing block 28 presses against the lid 25 and moves downward. When the lowermost lid 25 moves downward, it presses against the limiting block 30 of the telescopic limiting member and moves into the notch 29, and the spring column 31 is compressed to store elastic potential energy. When the lowermost lid 25 passes over the limiting block 30, the cylinder 27 stops running. At this time, the lowermost lid 25 falls from the opening below the lid placing groove 24 onto the top of the target transparent container 22 to complete the lid covering work, and the lowermost lid 25 in the lid placing groove 24 is blocked by the limiting block 30 and cannot move downward and waits for the next round of lid covering work. Among them, the feeding port 26 is provided to facilitate the feeding of the lid 25 into the lid placing groove 24.

[0039] In addition, the present application is provided with a movable observation assembly, which is convenient for the staff to observe the reagent products in each transparent container 22 more clearly in the subsequent comparison, and the movable observation assembly can adjust its position according to needs, which is more convenient to use. The specific usage process is as follows: The staff moves the concave plate 32 to a position aligned with the target transparent container 22 front and back, and observes the finished reagent in the target transparent container 22 more carefully through the magnifying glass 33 embedded on the inner wall of one side of the groove of the concave plate 32. At the same time, the supplementary light lamp 34 embedded on the inner wall of the other side of the groove of the concave plate 32 provides supplementary light for the observation to improve the observation effect. During the movement of the concave plate 32, the rollers 36 roll along the strip-shaped rail groove 37 to facilitate the adjustment of the position of the concave plate 32.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
