Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a reagent kit. In addition, the present invention also relates to a reagent kit storage tray, and a medical analyzer comprising the reagent kit and the reagent kit storage tray. Background Art

[0002] Currently, some in vitro diagnostic tests require solid-phase reagents, which must be mixed thoroughly before use. This requires the reagent bottles to be in constant motion when used in medical analyzers. Therefore, the reagent bottles must not only fit properly within the reagent rack but also maintain a stable rotational orientation. Furthermore, existing reagent bottle assembly designs and installation methods are limited, with varying drive and positioning methods across different instruments, making the reagent kits incompatible. Furthermore, during rotation and mixing, commercially available reagent kits experience significant frictional contact between the rotating surfaces of the reagent bottles, leading to powder shedding. This powder accumulates between the reagent bottle and the rack, hindering rotation and causing instrument-related drive system failures, leading to ineffective mixing. Thick puncture seals can create excessive reaction forces on the reagent needle when puncturing to obtain the reagent, and the diaphragm's return spring force is excessive, causing the needle and diaphragm to vibrate, leading to severe splashing. Flat seals are difficult to restore, leading to reagent volatilization and changes in magnetic bead concentration, affecting experimental results. During transportation, the test kit may fall over and the vibration may cause the magnetic beads to enter between the puncture cap and the sealing cap, causing the concentration of the magnetic beads to change and affecting the test results of the reagent.

[0003] Therefore, how to improve the applicability of the kit is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0039] The core of the present invention is to provide a reagent kit that can be automatically assembled, significantly improving assembly efficiency. Another core of the present invention is to provide a reagent kit storage tray and a medical analyzer including the reagent kit and the reagent kit storage tray.

[0042] In this embodiment, the reagent kit 2 includes a reagent kit rack 2-3, the bottom of which is provided with a reagent kit guide groove 2-8. The reagent kit guide groove 2-8 can be slidably engaged with the guide bar 3-4 of the first reagent kit storage tray. Specifically, the front end of the reagent kit guide groove 2-8 is first inserted into the rear end of the guide bar 3-4, and then the reagent kit rack 2-3 is pushed until the rear end of the reagent kit guide groove 2-8 corresponds to the rear end of the guide bar 3-4; the reagent kit guide groove 2-8 and the guide bar 3-4 are longitudinally engaged. Specifically, the reagent kit guide groove 2-8 and the guide bar 3-4 are preferably T-shaped or dovetail-shaped. At the same time, to facilitate processing and assembly, the front end of the bottom of the reagent kit rack 2-3 is provided with a first boss and a second boss, and the rear end is provided with a third boss and a fourth boss. The first boss and the second boss can be simultaneously slid into the guide bar 3-4, and then gradually pushed to the front end of the guide bar 3-4 until the third boss and the fourth boss simultaneously slide into the rear end of the guide bar 3-4, completing assembly. The longitudinal clamping of the reagent reagent guide groove 2-8 and the guide bar 3-4 can be achieved by the longitudinal clamping between the first and second bosses and the third and fourth bosses and the guide bar 3-4.

[0043] The reagent kit 2 provided by the present invention utilizes the cooperation of the reagent kit guide groove 2-8 and the guide bar 3-4 to realize the sliding assembly of the reagent kit rack 2-3, which makes the assembly more stable and convenient. The reagent kit guide groove 2-8 can also be applied to the reagent kit storage tray 3 with the positioning tongue 3-6 in the prior art, and has a wide range of applications.

[0044] Specifically, the reagent kit rack 2-3 is preferably an integrated structure, and the reagent kit rack 2-3 is provided with several reagent compartments and at least one bottle holder. The several reagent compartments can realize the independent coexistence of multiple reagents for use in the instrument. Specifically, the partition between two adjacent reagent compartments can be eliminated, and a larger reagent compartment exists. Specifically, this can be achieved by adjusting the structure of the mold when processing the reagent kit rack 2-3. Since the external structure of the reagent kit rack 2-3 does not change, it does not affect the use in the instrument. Several reagent bottles 1 are placed in the reagent kit rack 2-3, and the top of the reagent bottle 1 is provided with a reagent bottle 1 cover. The opening of the reagent bottle 1 cover is provided with an easy-tear film 1-3, and the reagent bottle 1 cover is installed with a silicone plug 1-4.

[0045] In addition to the aforementioned embodiments, the reagent rack 2-3 is further provided with a radial engaging portion 2-2 that engages radially with a radial latch 3-5 on the first reagent rack along the radial direction of the first reagent rack. Specifically, the radial engaging portion 2-2 is located at the bottom of the reagent rack 2-3 and extends vertically along the front inner wall of the reagent rack 2. The front inner wall of the reagent rack 2 faces the rear end of the reagent rack 2-3, facilitating engagement with the radial latch 3-5 at the bottom of the reagent rack 3.

[0046] Based on the above embodiments, the reagent kit rack 2-3 is provided with a gripper positioning portion for gripping by the manipulator 5. After the manipulator 5 engages with the gripper positioning portion, the reagent kit rack 2-3 can be pushed radially inward from the radial outer side of the first reagent kit storage tray until the radial engaging portion 2-2 engages with the radial snap 3-5. Specifically, the gripper positioning portion is a reagent kit positioning hole 2-5 provided on the side of the reagent kit rack 2-3. The reagent kit positioning hole 2-5 can be grasped by the manipulator 5 to achieve automatic assembly of the reagent kit 2. Preferably, one side of the reagent kit rack 2-3 has a single reagent kit positioning hole 2-5, and two side of the reagent kit positioning holes 2-5 have two reagent kit positioning holes 2-5. The three reagent kit positioning holes 2-5 achieve three-point positioning, ensuring stable and secure handling and convenient operation.

[0047] Based on the above embodiments, the reagent reagent guide groove 2-8 is T-shaped or dovetail-shaped, and the front width of the opening of the reagent reagent guide groove 2-8 is greater than the rear width. That is, the distance between the third and fourth bosses is greater than the distance between the first and second bosses. This makes the reagent reagent guide groove 2-8 form a continuous "V" shape along the front-to-back direction of the reagent reagent rack 2-3, facilitating installation and positioning. Specifically, the outer width of the guide bar 3-4 of the first reagent reagent storage tray is greater than the inner width. This arrangement effectively prevents friction between the reagent reagent guide groove 2-8 and the guide bar 3-4, making assembly more convenient.

[0048] Based on the above embodiments, the rear end of the reagent box rack 2-3 is further provided with a rear end buckle 2-1, which can be longitudinally engaged with the second reagent box storage tray; the front end of the reagent box guide groove 2-8 can be engaged with the positioning tongue 3-6 of the second reagent box storage tray.

[0049] Specifically, the second reagent box storage tray includes a storage tray body and ribs 3-1 located on both sides of the storage position of the storage tray body. The ribs 3-1 can limit the left and right positions of the reagent box rack 2-3. The storage position of the storage tray body is close to the inner side of the storage tray body and is provided with a positioning tongue 3-6.

[0050] like Figure 6 and Figure 7 As shown, the assembly process of the reagent kit 2 and the second reagent kit storage tray is as follows:

[0051] The front end of the reagent kit 2 is tilted downward and placed in the reagent kit 2 storage position on the second reagent kit storage tray, and the baffles on both sides of the storage position are used to position the reagent kit 2 left and right, and the front end of the reagent kit guide groove 2-8 is stuck with the positioning tongue 3-6 on the second reagent kit storage tray; the reagent bottle mixing gear 1-2 and the fixed mixing tooth 3-3 are engaged; the rear end of the reagent kit 2 is pressed down, and after a click, the rear end buckle 2-1 of the reagent kit 2 and the rear end buckle positioning surface 3-7 on the second reagent kit storage tray are stuck. At this time, the reagent kit 2 is positioned front and back, and the arc surface is tightly fitted with the arc surface for positioning the reagent kit 2 front and back under the action of the elastic force of the rear end buckle 2-1 of the reagent kit 2; the order can be reversed to achieve fixation; the movable block 4 can adjust the height position according to the height of the scanning mechanism of the equipment.

[0052] On the basis of the above embodiments, the side surface of the reagent kit rack 2-3 has at least one contoured positioning portion 2-6 extending in the longitudinal direction. The contoured positioning portion 2-6 has a similar structure to the side wall of the rib 3-1 of the third reagent kit storage tray. After the contoured positioning portion 2-6 is assembled with the rib 3-1 in the longitudinal direction, the contoured positioning portion 2-6 and the rib 3-1 can be clamped in the radial direction of the third reagent kit storage tray to achieve front, back, left and right positioning of the reagent kit rack 2-3; further, the side surface of the reagent kit rack 2-3 is also provided with a side clamping portion 2-7 that can be clamped in the longitudinal direction with the rib 3-1 of the third reagent kit storage tray to achieve upper and lower positioning of the reagent kit rack 2-3.

[0053] Furthermore, the contoured positioning portion 2-6 is a contoured positioning groove, and correspondingly, the rib 3-1 of the reagent storage tray 3 should be provided with a positioning boss. This arrangement, utilizing the contoured positioning groove, allows the reagent rack 2-3 and the reagent storage tray 3 to be quickly and easily positioned while also achieving radial engagement between the two in the reagent storage tray 3. In other words, the contoured positioning portion 2-6 can both meet the requirement for rapid positioning and provide radial positioning of the reagent storage tray 3. Of course, the contoured positioning portion 2-6 can also be a contoured positioning boss, and correspondingly, the rib 3-1 of the reagent storage tray 3 should be provided with a positioning groove. Preferably, to enhance assembly convenience, the contoured positioning groove is preferably arc-shaped along the radial direction of the reagent storage tray 3.

[0054] Furthermore, the side of the reagent box rack 2-3 is also provided with a side clamping portion 2-7 that can be longitudinally clamped with the retaining edge 3-1 of the reagent box storage tray 3. Specifically, at least one side of the reagent box rack 2-3 is provided with a side clamping portion 2-7, and the side clamping portion 2-7 can cooperate with the side clamping platform 3-1-2 on the retaining edge 3-1 of the reagent box storage tray 3 to achieve longitudinal clamping and limiting of the two.

[0055] Preferably, the side engaging portion 2-7 is an elastic side buckle that can engage with the side engaging platform 3-1-2 located on the rib 3-1. The elastic side buckle is easy to use and is provided with an introductory bevel. When the reagent rack 2-3 is inserted into the reagent rack storage tray 3, the introductory bevel on the elastic side buckle first contacts the side engaging platform 3-1-2 on the rib 3-1 of the reagent rack storage tray 3. As the reagent rack 2-3 moves downward, the elastic side buckle moves toward the inside of the reagent rack 2-3 until the elastic side buckle engages with the side engaging platform 3-1-2. When the reagent rack 2-3 needs to be removed, it can be pulled out by applying force in the opposite direction. This is convenient to operate and provides reliable positioning.

[0056] Furthermore, the contoured positioning groove has an arcuate recessed surface, and a central portion of the contoured positioning groove is provided with a positioning arc surface. The side walls of the contoured positioning groove and the positioning arc surface form a "mountain"-shaped structure. Specifically, the side edges of the reagent kit rack 2-3 are designed to resemble a "mountain" shape. After installation on the reagent kit storage tray 3, multiple positions can be positioned and limited, ensuring accurate positioning and stable installation. Of course, the aforementioned "mountain"-shaped structure is the preferred embodiment, and other structures can be substituted, allowing for longitudinal assembly or radial snap-fitting.

[0057] Furthermore, a reagent retrieval portion 2-4 is provided above the contoured positioning groove for the operator to access. The reagent retrieval portion 2-4 may be a concave-convex portion. Specifically, the reagent retrieval portion 2-4 is provided on the side of the reagent retrieval rack 2-3, preferably above the side engaging portion 2-7. This structural design reduces the overall dimensions of the reagent retrieval rack 2, improves the space utilization of the reagent retrieval rack 2, and effectively ensures storage space in the reagent compartment.

[0058] Specifically, the third reagent cartridge storage tray includes a storage tray body and side ribs 3-1 located on either side of the storage area of ​​the storage tray body. The side ribs 3-1 can limit the left and right positions of the reagent cartridge rack 2-3. Side ribs 3-1-1 extending longitudinally are provided on the sides of the side ribs 3-1 near the storage area. The side ribs 3-1-1 allow for longitudinal assembly of the contoured positioning portion 2-6 of the reagent cartridge rack 2-3 and engage radially with the storage tray body. Preferably, the side ribs 3-1 have a "mountain"-shaped structure that mates with the "mountain"-shaped structure of the side ribs of the reagent cartridge rack 2-3. Furthermore, to enhance the installation stability of the reagent cartridge rack 2-3, both side ribs 3-1 on the storage tray body's storage area are provided with side ribs 3-1-1, and the structures of the two sides are preferably identical.

[0059] Furthermore, the side of the third reagent storage tray 3-1 near the storage position is provided with a side clamping platform 3-1-2. After the reagent rack 2-3 is assembled, the side clamping platform 3-1-2 can be longitudinally clamped with the side clamping portion 2-7 of the reagent rack 2-3. Furthermore, the storage tray body of the third reagent storage tray is also provided with a plurality of mixing claws 3-2. The mixing claws 3-2 can cooperate with the mixing ribs of the reagent bottle 1 in the reagent rack 2 to drive the reagent bottle 1 to rotate and achieve a mixing effect.

[0060] like Figure 8 and Figure 9 As shown, the assembly process of the reagent kit 2 and the third reagent kit storage tray is as follows:

[0061] When the reagent box 2 is placed downward, the reagent box 2 is positioned in the left, right, front and back directions by relying on the mountain-shaped structure on the side of the retaining edge 3-1 in the third reagent box storage tray, and the positioning is accurate; when it is placed at the bottom, the side buckles on the side of the reagent box 2 are inserted into the side clamping platforms 3-1-2 on the side of the retaining edge 3-1 of the third reagent box storage tray to lock the upper and lower positions; at this time, the reagent bottle mixing and stirring ribs 1-1 on the reagent bottle 1 in the reagent box 2 cooperate with the mixing and stirring claws 3-2 to drive the reagent bottle 1 to rotate forward and reverse to perform the mixing function; the movable block 4 can adjust the height position according to the height of the scanning mechanism of the equipment.

[0062] Based on the above embodiments, the reagent kit rack 2-3 comprises a main portion corresponding to the length of the storage space of the reagent kit storage tray 3 and an extension portion extending beyond the storage space. The extension portion is provided with at least one reagent bottle 1 receiving cavity within the extension portion. This configuration, by extending the reagent kit rack 2-3, increases the reagent kit rack 2-3's storage capacity without affecting assembly with the reagent kit storage tray 3. Specifically, during actual manufacturing, only the extension portion for at least one reagent bottle 1 receiving cavity needs to be added to the mold, making modification easy and cost-effective.

[0063] It should be noted that the reagent kit storage tray 3 referred to in this application includes but is not limited to the first reagent kit storage tray, the second reagent kit storage tray and the third reagent kit storage tray.

[0064] On the basis of the above embodiments, a movable block 4 is provided at the rear end of the reagent kit rack 2 - 3 . The position of the movable block 4 relative to the reagent kit rack 2 - 3 is adjustable, and an identification portion is provided on the movable block 4 .

[0065] In addition to the reagent kit 2 described above, the present invention further provides a reagent kit storage tray 3. This reagent kit storage tray 3 is a first reagent kit storage tray and includes a storage tray body and ribs 3-1 located on either side of a storage area within the storage tray body. The ribs 3-1 limit the left and right positions of the reagent kit 2. The surface of the storage area is provided with guide bars 3-4 that can slideably engage with the reagent kit guide grooves 2-8 of the reagent kit rack 2-3 along the radial direction of the storage tray body. The guide bars 3-4 are longitudinally engaged with the reagent kit guide grooves 2-8.

[0066] Furthermore, it also includes a radial buckle 3-5 located at the bottom of the storage tray body, and the radial buckle 3-5 can be snapped with the radial snap-fit ​​portion 2-2 of the reagent kit rack 2-3.

[0067] Specifically, the middle part of the radial buckle 3-5 is hinged to the storage disk body, and an elastic component that can reset the radial buckle 3-5 is installed at the hinge point; one end of the radial buckle 3-5 is provided with a clamping surface that can be clamped with the radial clamping part 2-2, and the other end is provided with an unlocking inclined surface; when the manipulator 5 moves to abut against the unlocking inclined surface, the unlocking inclined surface will drive the radial buckle 3-5 to rotate so that the clamping surface is away from the radial clamping part 2-2 to achieve unlocking.

[0068] Specifically, a fixed mixing gear 3-3 is provided in the middle of the storage tray body. When the reagent kit rack 2-3 is loaded into the first reagent kit storage tray, the fixed mixing gear 3-3 can engage with the reagent bottle mixing gear 1-2 on the reagent bottle 1 in the reagent kit rack 2-3.

[0069] like Figures 3 to 5 As shown, the assembly process of the reagent kit 2 and the first reagent kit storage tray given in this embodiment is as follows:

[0070] The reagent container rack 2-3 is provided with reagent container positioning holes 2-5 on both sides. When automatically placing and removing the reagent container 2, the fingers of the manipulator 5 gripper are inserted into the reagent container positioning holes 2-5 of the reagent container 2 to prevent displacement or flipping during the movement of the reagent container 2. First, the front end of the reagent container guide groove 2-8 is inserted into the guide bar 3-4, pushing the reagent container 2 inward. The left and right directions of the reagent container 2 are limited by the retaining edge 3-1 of the first reagent container storage tray to achieve left and right positioning. When the reagent bottle mixing gear 1-2 is engaged with the mixing fixed gear disk, the rear end of the reagent container guide groove 2-8 is also inserted into the guide bar tail 3-4-1 to achieve the upper and lower limits of the reagent container 2. When the reagent container 2 is pushed to the target position, the radial buckle 3-5 pops up and cooperates with the inner wall surface of the front end of the reagent container 2. At this time, the reagent container 2 will not be able to move forward and backward. The shape of the guide bar 3-4 and the reagent container guide groove 2-8 can be T-shaped or dovetail-shaped, and can also be set according to specific needs to achieve the guiding and limiting function. The movable block 4 can adjust the height position according to the height of the scanning mechanism of the device.

[0071] In addition to the above-mentioned reagent kit 2 and the first reagent kit storage tray, the present invention further provides a medical analyzer including the above-mentioned reagent kit 2 and the first reagent kit storage tray. The medical analyzer can be a biochemical analyzer, a chemiluminescence analyzer, a urine analyzer, a nucleic acid analyzer, or the like.

[0072] Preferably, the manipulator 5 for controlling the radial buckle 3-5 and the manipulator 5 for grabbing the reagent kit 2 can be integrated into one, that is, the medical analyzer also includes a manipulator 5, and the manipulator 5 is provided with a clamp for grabbing the reagent kit 2, and an arm for unlocking the radial buckle 3-5. The length of the arm should correspond to the position of the radial buckle 3-5, that is, after the clamp of the manipulator 5 moves the reagent kit 2 to the target position, the arm just disengages from the radial buckle 3-5, and the radial buckle 3-5 locks the reagent kit 2 laterally.

[0073] Preferably, a roller is provided at the end of the arm, and the roller can roll with the unlocking inclined surface.

[0074] For the structures of other parts of the medical analyzer, please refer to the existing technology and will not be described in detail in this article.

[0075] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
