Description

Technical Field

[0001] The present invention relates to the technical field of biochemical immunoassay equipment, and in particular to a reagent box storage mechanism used in a biochemical immunoassay all-in-one machine. Background Art

[0002] Biochemical analysis is a common and important tool in clinical diagnosis. By analyzing blood or other body fluids to measure various biochemical indicators and combining them with other clinical data for comprehensive analysis, it can help diagnose diseases, evaluate organ function, identify complications, and determine the basis for future treatment. Biochemical analyzers are primarily used for quantitative determination of biochemical and chemical components of clinical blood and other body fluid samples, such as hemoglobin, cholesterol, triglycerides, albumin, C-reactive protein, glucose, potassium, sodium, and calcium. They are one of the most commonly used instruments in clinical analysis.

[0003] In the biochemical analysis process, reagents are used to react with samples to produce test reactants for clinical observation. The storage mechanism of the reagents has high requirements, that is, low-temperature storage is generally required, and it is necessary to facilitate the operation of reagent retrieval, replacement, and addition. At the same time, since the magnetic beads in the reagent are prone to precipitation when left unmoved for a long time, affecting the concentration of the magnetic beads in the reagent, in order to improve the accuracy and stability of the reagent test results, the magnetic beads in the reagent need to be mixed, so the test kit storage mechanism also needs to have a shaking function. In the existing technology, the fully automatic test kit storage mechanism usually shakes the test agent by shaking the entire test kit. This shaking method has the following disadvantages: 1. The shaking amplitude is large, which is easy to cause certain damage to the test kit itself; 2. The overall shaking is uneven for each test agent, that is, the uniformity of the shaking cannot be guaranteed for the test agent, making the test agent in poor condition. Summary of the Invention

[0038] The technical solutions of the present invention will be clearly and completely described below through specific implementation methods. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1 to 13 As shown, a reagent box storage mechanism includes a reagent compartment body 1, a reagent compartment cover 2 and a reagent compartment base 3. The reagent compartment body 1 is fixed on the reagent compartment base 3 and its top surface is covered with a reagent compartment cover 2. In order to meet the requirements of low-temperature storage, a refrigeration device 4, a support column 5 and a thermal insulation pad 6 are also provided on the reagent compartment base 3, wherein the support column 5 is vertically arranged on the reagent compartment base 3, the refrigeration device 4 is fixed on the reagent compartment base 3 and its top surface is in contact with the bottom surface of the reagent compartment body 1. The main function of the refrigeration device 4 is to cool and cool the inside of the reagent compartment body 1 and control the temperature of the reagent box 21 within a suitable range. The reagent compartment body 1 is fixed on the support column 5 and an insulation pad 6 is provided at the connection between the two. The main function of providing the insulation pad 6 is to prevent the heat emitted by the refrigeration device 4 during refrigeration from being transferred upward from the support column 5 to the reagent compartment body 1, causing the refrigeration effect to deteriorate.

[0040] A reagent box storage port 7 is provided on the reagent compartment cover 2 and a storage door mechanism is provided on the reagent box storage port 7. The storage door mechanism includes a movable plate 8, a door plate 9, a cover plate 10 and a door body driving member. The top surface of the reagent compartment cover 2 is recessed with a movable groove 11, and the bottom of the groove at both ends of the movable groove 11 are respectively provided with a reagent box storage port 7 and a circular driving through hole 12. The cover plate 10 is covered on the top of the movable groove 11 and a gap is left between the cover plate 10 and the bottom of the movable groove 11 for moving the movable plate 8. The function of the cover plate 10 is to limit the movement of the movable plate 8 in its vertical direction. At the same time, a door plate movable through hole 13 is provided at the position of the cover plate 10 corresponding to the reagent box storage port 7. The door plate 9 covers the door plate movable through hole 13 and its bottom is fixedly connected to the top surface of the movable plate 8.

[0041] The door drive member is arranged at the bottom of the reagent compartment cover 2 and passes through the circular drive through-hole 12 to be driven and connected to the movable plate 8. Furthermore, the door drive member includes a door drive motor 14, a motor fixing frame 15, and a turntable 16. The motor fixing frame 15 is arranged at the bottom of the reagent compartment cover 2. The turntable 16 is arranged between the motor fixing frame 15 and the reagent compartment cover 2 and a drive shaft 17 is vertically arranged on the top surface thereof corresponding to the circumferential side of the circular drive through-hole 12. The door drive motor 14 is fixed to the bottom of the motor fixing frame 15 and its output shaft passes through the center position of the motor fixing frame 15 and is driven and connected to the turntable 16. A long strip transmission hole 18 is provided at the position of the movable plate 8 corresponding to the circular drive through-hole 12. The top end of the drive shaft 17 passes through the circular drive through-hole 12 and is placed in the long strip transmission hole 18. When the reagent box 21 needs to be taken out and placed, that is, when the reagent box storage port 7 needs to be exposed, the door drive motor 14 drives the turntable 16 to rotate, so that the drive shaft 17 on the turntable 16 rotates along the circumference of the circular drive through hole 12 and moves along its length direction in the long strip transmission hole 18, so as to convert the circular motion of the turntable 16 into the linear motion of the moving plate 8, so that the moving plate 8 moves back and forth in the moving groove 11 and drives the door panel 9 to cover or leave the reagent box storage port 7, thereby realizing the automatic opening and closing of the storage door mechanism.

[0042] In addition, a sensor (not shown) can be provided on the bottom surface of the reagent compartment cover 2 to read and record the basic information of the reagent kit 21. When the reagent kit 21 is exhausted, real-time feedback information can be provided to remind the staff to replace it in time.

[0043] The reagent bin body 1 includes a reagent bin chamber, a reagent tray 19, a shaking mechanism and a rotating mechanism. The reagent tray 19 is rotatably arranged at the bottom of the reagent bin chamber and a plurality of racks for placing reagent kits are arranged uniformly along its circumferential direction. Each rack is composed of two wedge-shaped positioning blocks 20. Two adjacent racks share one wedge-shaped positioning block 20. At the same time, both sides of each wedge-shaped positioning block 20 are provided with guide grooves 22. The reagent kit 21 is stored in a low-temperature environment and condensed water will condense on its surface. In order to prevent too much condensed water from adhering to its surface when the reagent kit 21 is placed or removed, a guide groove 22 is provided on the side of the wedge-shaped positioning block 20. In this way, during the process of taking out or putting in, the side of the reagent kit 21 will contact the side of the wedge-shaped positioning block 20, and most of the condensed water will be scraped away and discharged along the guide groove 22. The wedge-shaped positioning blocks 20 contained in the plurality of racks are uniformly arranged along the circumferential direction of the reagent tray 19, and a plurality of reagent kits 21 are arranged in two adjacent wedge-shaped positioning blocks 20. In addition, since the reagent box 21 is subjected to centrifugal motion when the reagent tray rotates, a protrusion 49 is provided at the bottom of the wedge-shaped positioning block 20 away from the center of the reagent tray 19 to prevent the reagent box 21 from flying out during rotation.

[0044] The rotating mechanism is arranged on the reagent bin base 3 and extends into the reagent bin main body 1 and is drivingly connected with the reagent disc 19, so that the reagent disc 19 drives the multiple groups of placing racks to rotate along the circumferential direction of the reagent disc 19. Meanwhile, each group of placing racks is rotatably provided with a uniforming support 23 at the position of the center of the reagent disc 19, and the uniforming mechanism is arranged on the reagent bin base 3 and extends into the reagent bin main body 1 and is drivingly connected with the multiple uniforming supports 23 to make the multiple uniforming supports 23 rotate.

[0045] The structure inside the reagent bin main body will be further described as follows:

[0046] The reagent bin cavity is composed of an inner heat preservation cover 24, an outer heat preservation cover 25 and a reagent bin bottom plate 26. The inner heat preservation cover 24 and the outer heat preservation cover 25 are arranged on the reagent bin bottom plate 26 and coaxially arranged, and together with the refrigerating device 4 on the reagent bin base 3 to ensure the low-temperature environment inside the reagent bin cavity. The reagent disc 19 is specially designed as a ring structure and is arranged between the inner heat preservation cover 24 and the outer heat preservation cover 25 to match the structural features of the two.

[0047] The top surface of the reagent bin bottom plate 26 is uniformly provided with multiple reagent disc support seats 27 along the circumferential direction of the reagent disc 19. The reagent disc support seat 27 comprises an L-shaped base 2701, a cantilever shaft 2702 and a support roller 2703. The L-shaped base 2701 is vertically arranged on the reagent bin bottom plate 26 and the cantilever shaft 2702 is fixed at the center position of the side of the L-shaped base 2701 which is not fixed to the reagent bin bottom plate 26 along the radial direction of the reagent disc 19. The support roller 2703 is arranged on the cantilever shaft 2702 through a bearing. The bottom surface of the reagent disc 19 is in contact with the circumferential surface of the multiple support rollers 2703, so that the reagent disc 19 can rotate relative to the reagent bin bottom plate 26, so as to be matched with the rotating mechanism to realize the rotation of the reagent disc 19.

[0048] In this embodiment, the rotating mechanism adopts a gear transmission mode. Specifically, the rotating mechanism comprises a rotating driving member and a rotating disc 28. The rotating disc 28 is designed as a ring structure to adapt to the internal structure of the reagent bin cavity and is fixed to the bottom of the reagent disc 19 as the rotating disc 19. Multiple rotating teeth 29 are uniformly arranged on the inner circumferential surface of the rotating disc 28.

[0049] Afterwards, the rotation drive member includes a rotation motor base 30, a rotation motor 31, a transmission assembly 32, a rotation shaft 33 and a rotation gear 34. The rotation motor base 30 is fixed on the reagent chamber base 3 and is vertically provided with multiple auxiliary support shafts 35 and is fixedly connected to the bottom surface of the reagent chamber base plate 26 to further support the reagent chamber main body 1. The rotation shaft 33 is vertically arranged on the rotation motor base 30 by an axle fixing seat 36, and the top of the rotation shaft 33 needs to penetrate the reagent chamber base plate 26 and extend into the reagent chamber inside and be coaxially fixed with a rotation gear 34 at its top, and this rotation gear 34 is meshed and connected with a plurality of rotation teeth 29 on the rotating disk 28. The rotation motor 31 is then arranged on the rotation motor base 30 and its output shaft is driven and connected to one end of the rotation shaft 33 that is not fixed with the rotation gear 34 through the transmission assembly 32.

[0050] When it is necessary to rotate the reagent tray 19 to rotate a reagent kit 21 thereon to the reagent kit storage port 7, the rotating motor 31 drives the rotating shaft 33 to rotate through the transmission assembly 32. The rotation of the rotating shaft 33 drives the rotating gear 34 on its top to rotate, thereby rotating the rotating disk 28 meshed with the rotating gear 34, so that the reagent tray 19 fixed on the rotating disk 28 can rotate relative to the reagent compartment bottom plate 26 under the action of the supporting roller 2703 of the reagent tray support seat 27, thereby driving the multiple groups of placement racks thereon to rotate along the circumferential direction of the reagent tray 19 and causing a specific corresponding reagent kit 21 to rotate to the reagent kit storage port 7. At this time, the door body drive motor 14 in the storage door mechanism is started, and through a series of mechanical transmissions, the movable plate 8 moves in the movable groove 11, and drives the door plate 9 to leave the reagent kit storage port 7 to expose the reagent kit storage port 7, which is convenient for reagent removal.

[0051] Because multiple reagent kits are placed on the reagent tray 19, the overall stability of the reagent tray 19 must be maintained during its rotation to prevent deviation. Therefore, a mechanism with a movable guide or limit function is specifically configured for the rotation mechanism. Specifically, a circular guide block 37 is fixedly disposed between the rotating disk 28 and the reagent tray 19. Multiple movable guide members 38 are evenly fixedly disposed on the reagent compartment base plate 26 along the inner circumference of the circular guide block 37. These movable guide members include a convex fixing seat 3801 and a movable guide wheel 3802. The convex fixing seat 3801 is fixed to the reagent compartment base plate 26, and a movable guide wheel 3802, coaxially arranged with the reagent tray 19, is fixed to its top via a bearing. To provide the movable guide or limit function, the circumferential side surfaces of the movable guide wheels 3802 must be tangential to the inner circumferential side surfaces of the circular guide block 37. Simultaneously, the top and bottom surfaces of the movable guide wheels 3802 must contact the bottom surface of the reagent tray 19 and the top surface of the rotating disk 28, respectively. The mutual restriction between the movable guide wheel 3802 and the circular guide block 37 ensures that the reagent disk 19 rotates smoothly.

[0052] Due to the requirements of the immunoassay principle, the magnetic beads / particles in the reagent kit 21 must always remain free, so the reagent kit 19 needs to be continuously shaken. Therefore, a shaking mechanism is also provided within the reagent compartment body 1. The shaking mechanism includes a shaking drive and a shaking turntable 39. Like the rotating disk 28, the shaking turntable 39 needs to be designed to adapt to the internal structure of the reagent compartment chamber. The ring-shaped structure is rotated by a connecting slide and is arranged on the inner circumference of the reagent tray 19.

[0053] The shake mechanism also uses a gear drive system. A plurality of shaker teeth 40 are evenly distributed on the inner circumference of the shaker disc 39, and a plurality of transmission teeth 41 are evenly distributed on the outer circumference of the shaker disc 39. A shaker gear 42 is fixedly mounted on the bottom of each shaker bracket 23 and meshes with the transmission teeth 41 on the shaker disc 39.

[0054] The shake drive comprises a shake motor base 43, a shake motor 44, a transmission assembly 32, a shake shaft 45, and a shake rotation gear 46. The shake motor base 43 is fixed to the reagent compartment base 3 and is vertically provided with multiple auxiliary support shafts 35 and fixedly connected to the bottom surface of the reagent compartment base plate 26 to further support the reagent compartment body 1. The shake shaft 45 is vertically arranged on the shake motor base 43 through an axle fixing seat 36. At the same time, the top of the shake shaft 45 passes through the reagent compartment base plate 26 and extends into the interior of the reagent compartment and is coaxially fixed with a shake rotation gear 46 at its top. The shake rotation gear 46 is meshed with multiple shake rotation teeth 40 on the shake turntable 39. The shake motor 44 is arranged on the shake motor base 43 and its output shaft is drivingly connected to the end of the shake shaft 45 not fixed with the shake rotation gear 46 through the transmission assembly 32.

[0055] Furthermore, a heat insulation plate 50 is also provided at the connection between the above-mentioned rotating shaft 33, the shaking shaft 45 and the bottom plate 26 of the reagent chamber. The main function of the heat insulation plate 50 is to prevent the cold air in the cavity from being transmitted downward along the rotating shaft 33 and the shaking shaft 45. Since the air at the bottom of the reagent chamber is hotter than the air inside the chamber, condensation water will form when encountering the colder rotating shaft 33 and the shaking shaft 45, and will adhere to them and flow downward, causing corrosion of the shaft body and the bearings inside the shaft fixing seat 36. Therefore, the heat insulation plate 50 is provided to avoid the above situation.

[0056] In order to keep the shaking bracket 23 driving the reagent to rotate at all times, the shaking motor 44 continuously drives the shaking shaft 45 to rotate, and the rotation of the shaking shaft 45 drives the shaking rotating gear 46 on its top to rotate, and then the shaking rotating gear 46 is engaged with the shaking rotating gear 40 and the transmission gear 41 is engaged with the shaking gear 42 at the bottom of each shaking bracket 23, so that multiple shaking brackets 23 rotate.

[0057] The shaking turntable 39 also needs to remain stable when rotating and avoid axial deflection. Therefore, similar to the rotating mechanism, a series of guide and limiting structures are also designed for the shaking turntable 39. Specifically, a guide groove 47 is recessed on the circumferential side of the inner ring of the shaking turntable 39, and a plurality of shaking guide members 48 are evenly fixed on the reagent compartment bottom plate 26 along the circumferential direction of the inner ring of the shaking turntable 39. The shaking guide members 48 include a convex guide seat 4801 and a shaking guide wheel 4802. The convex guide seat 4801 is fixed on the reagent compartment bottom plate 26 and a shaking guide wheel 4802 is fixed on its top through a bearing and is coaxially arranged with the shaking turntable 39. In order to play a guiding or limiting role, the circumferential side of the shaking guide wheel 4802 needs to be tangent to the bottom surface of the guide groove 47, and the top and bottom surfaces of the shaking guide wheel 4802 need to contact the top groove wall and bottom groove wall of the guide groove 47 respectively. By limiting the mutual position of the shaking guide wheel 4802 and the guide groove 47, the smooth rotation of the shaking turntable 39 is ensured, and each shaking bracket 23 can rotate on its own.
