Description

Technical Field

[0001] The utility model relates to the technical field of immunoassay analyzers in medical devices, and particularly relates to an integrated sample storage device for an immunoassay analyzer. Background Technique

[0002] Chemiluminescence-labeled immunoassay, also known as chemiluminescence immunoassay (CLIA), is an immunoassay method that directly labels antigens or antibodies with chemiluminescent agents. A chemiluminescence immunoassay analyzer consists of two parts, namely an immune reaction system and a chemiluminescence analysis system. Among them, in the immune reaction system, a luminescent substance (generating an excited intermediate under the excitation of a reactant) is directly labeled on an antigen (chemiluminescence immunoassay) or an antibody (immunochemiluminescence assay), or an enzyme acts on a luminescent substrate.

[0003] In an immunoassay analyzer, it is necessary to store and place reagents, samples, etc., so that reagents or samples can be taken and placed at any time during the detection operation. At the same time, during the detection and analysis process, corresponding waste of detection consumables will also be generated, which needs to be collected and stored uniformly. Therefore, it is necessary to design a special storage device to meet the corresponding requirements. Since the design and manufacture of immunoassay analyzers tend to be modular, integrated, and miniaturized, there is still a certain room for optimization in the storage of reagents, samples, waste, etc., in order to store them as concentrated as possible to save the internal space of the instrument.

[0004] Through retrieval, there is a technical solution for a test tube rack in an immunoassay analyzer disclosed in the prior art at present. For example, the invention patent announcement document with the publication number "CN115267235A" and the name "Sampling Module and Single-Molecule Immunoassay Analyzer Containing the Same". It discloses a sampling module and a single-molecule immunoassay analyzer containing the same. The sampling module includes 2 to 4 layers of sample racks, and each layer of sample rack is arranged in parallel in the vertical direction and has the same structure. Each includes a microplate, a stage, a linear reciprocating motion mechanism, and the linear reciprocating motion mechanism includes a linear guide rail, a driving mechanism, a drawer slide rail, a synchronous belt, a driving wheel, a driven wheel, and a zero-position sensor. The single-molecule immunoassay analyzer includes a sampling module, a detection module, an incubation module, a reagent processing module, etc. This comparative document proposes corresponding technical solutions for sample injection, but it does not consider the integrated storage of samples such as microplates and test tubes, and still stores them separately, which is not conducive to space optimization.

[0005] The invention patent publication document with the publication number of "CN117233410A" and the name of "A fully automatic chemiluminescence immunoassay instrument" is disclosed. A fully automatic chemiluminescence immunoassay instrument is disclosed, including a sample tube rack automatic sampling device, a shaking device, a capping device, a reagent strip transfer device, a three-dimensional sample loading device and a photometric device. The sample tube rack automatic sampling device includes a lane and a sampling positioning push module. The sampling positioning push module can push the sample tube rack to move in the lane and stay in the shaking position, the capping position and the sampling position in the lane in turn; the shaking device can shake the sample tube located at the shaking position; the capping device can remove the tube cap of the sample tube located at the capping position; the reagent strip transfer device includes a drawer-type reagent strip storage mechanism and a reagent strip clamping mechanism; the three-dimensional sample loading device includes a sample loading movement component and a TIP loading component; the photometric device is used to measure the photometry of the reagent strip with the sample added. It can be seen from the contents of the records disclosed in the comparative document that the storage of its samples still does not consider the integrated design.

[0006] The applicant previously applied for an invention patent publication document with the publication number "CN117665307A" titled "An Immunoassay TIP Head Detection Method and Detection Device". The TIP head module drawer involved therein is also independently stored in the bottom space inside the instrument. Therefore, in view of the technical problems existing in the above-mentioned prior art, it is of great significance to propose an integrated sample storage device for an immunoassay analyzer.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1 to 6 , and Figures 10 to 12 shown. An integrated sample storage device for an immunoassay analyzer includes an outer frame assembly 6. Inside the outer frame assembly 6, there is a partition 61. The partition 61 divides the outer frame assembly 6 into upper and lower storage spaces. Above the partition 61, a test tube rack 7 and an orifice plate drawer 8 are carried. The orifice plate drawer 8, the test tube rack 7, and the partition 61 are all connected through the same installation interface. In the vacant area after the orifice plate drawer 8 is taken out, the test tube rack 7 can be installed on the partition 61 through installation interface one.

[0032] In this embodiment, the outer frame assembly 6 is a frame with an open top enclosed and spliced by a bottom plate and side plates. The partition 61 divides the outer frame assembly 6 into two storage spaces, upper and lower, which are respectively used to store samples and waste, making use of the height space and saving the lateral space. The test tube rack 7 and the well plate drawer 8 are connected to the partition 61 through the same installation interface, and the test tube rack 7 or the well plate drawer 8 can be flexibly selected to be placed on the partition 61 according to requirements.

[0033] In a more preferred embodiment, a number of installation slots 62 arranged side by side are connected to the partition 61. The installation of the test tube rack 7 occupies a single installation slot 62, and the well plate drawer 8 occupies an integer multiple of the space occupied by the test tube rack 7. In this embodiment, the occupied spaces of the well plate drawer 8 and the test tube rack 7 are optimized. When only the test tube rack 7 is installed on the partition 61, the upper surface of the entire partition 61 can be filled. When the well plate drawer 8 needs to be installed, some of the test tube racks 7 are taken out, and this part of the space is used to install and store the well plate drawer 8. In this way, the well plate drawer 8 and the test tube rack 7 together also cover the upper surface of the partition 61, thus maximizing the utilization of space. In this embodiment, the space of one well plate drawer 8 can correspond to the installation of four test tube racks 7.

[0034] One possible implementation of the installation interface of the above-mentioned well plate drawer 8 and test tube rack 7 is that a number of T-shaped blocks 621 arranged side by side are connected to the partition 61. An installation slot 62 is formed between two adjacent T-shaped blocks 621. A sliding groove 11 matching the installation slot 62 is connected to the bottom of the test tube rack 7, and the test tube rack 7 can be slidably installed in the installation slot 62 through the sliding groove 11. Corresponding matching interfaces can be designed at the bottoms of both the well plate drawer 8 and the test tube rack 7 to achieve multiplex installation.

[0035] For example, a "Ji"-shaped mounting block 81 is connected to the bottom of the well plate drawer 8. The two side edges of the "Ji"-shaped mounting block 81 can be respectively embedded into two installation slots 62, and the well plate drawer 8 is slidably installed on the partition 61 through the "Ji"-shaped mounting block 81. The two edges of the "Ji"-shaped mounting block 81 can just be embedded into two installation slots 62. In this embodiment, the width of the "Ji"-shaped mounting block 81 is such that it occupies four installation slots 62. Therefore, the installation space of one well plate drawer 8 can be reused to install four test tube racks 7.

[0036] Alternatively, more than one sliding groove 11 is connected to the bottom of the well plate drawer 8, and the well plate drawer 8 is slidably installed on the partition 61 through the multiple sliding grooves 11. That is, the bottoms of both the well plate drawer 8 and the test tube rack 7 use the matching of the sliding groove 11 and the installation slot 62 to achieve sliding loading and unloading. The bottom of the test tube rack 7 uses a single sliding groove 11, while the well plate drawer 8 preferably uses multiple sliding grooves 11. For example, four sliding grooves 11 are used to occupy and embed four installation slots 62 to achieve the sliding loading and unloading of the well plate drawer 8.

[0037] In a more preferred embodiment, the T-shaped block 621 is formed by vertically connecting a transverse block 622 and a longitudinal block 623. The length of the transverse block 622 at the entrance of the installation groove 62 is shorter than that of the longitudinal block 623, and both the transverse block 622 and the longitudinal block 623 are provided with guiding openings 624 at the entrance of the installation groove 62. In order to make the sliding installation of the orifice plate drawer 8 and the test tube rack 7 more convenient, the guiding opening 624 of the longitudinal block 623 conducts preliminary guiding. The non-flush design where the length of the transverse block 622 at the entrance of the installation groove 62 is shorter than that of the longitudinal block 623 can make the positioning more accurate when the sliding groove 11 is slidably sleeved on the T-shaped block 621 and will not be blocked by its end face. When the sliding groove 11 initially enters the guiding opening of the longitudinal block 623, it will not contact the end face of the transverse block 622 at this time. After being guided, it continues to advance towards the transverse block 622 and is further guided by its guiding opening, making the installation and alignment process of the test tube rack 7 or the orifice plate drawer 8 more convenient.

[0038] As Figures 7 to 9 shown, the structure of the test tube rack 7 includes a bracket body 1, on which there is a straight row array with a receiving cavity 2. The side part of the bracket body 1 includes a code scanning and identification area 3 corresponding to the receiving cavity 2, and the code scanning and identification area 3 is inclined. In this embodiment, the test tubes 100 are neatly placed in a straight row in the receiving cavity 2, and the shape of the receiving cavity 2 is adapted to the outer shape of the test tubes 100. Each receiving cavity 2 has a corresponding code scanning and identification area 3, on which a bar code or a two-dimensional code for identification can be pasted. After the code scanning device scans the code scanning and identification area 3, the corresponding information of the corresponding test tube can be obtained. Therefore, each test tube 100 can be uniformly managed in an informatized manner, and this identification is unique. And the code scanning and identification area 3 is inclined to obtain a better scanning and identification effect. In this embodiment, the code scanning and identification area 3 is as Figure 1 shown in the figure, which is a rectangular area as a whole and is inclined at a certain angle towards the receiving cavity 2. When the code scanning device passes through the code scanning and identification area 3, the inclined setting makes the scanning faster and more accurate.

[0039] In a more preferred embodiment, the receiving cavity 2 has an opening 21 on one side of the code scanning and identification area 3, and the code scanning and identification area 3 is arranged in the planar area adjacent to the opening 21. The opening 21 makes the side wall of the receiving cavity 2 not completely continuously closed. When the test tube 100 is inserted into it, the opening 21 can play a role in discharging air and prevent the placement of the test tube 100 from being blocked. And the setting of the opening 21 can also make the whole test tube rack lighter in weight. Since the weight of the test tube 100 is light, this design structure will not cause the problem of insufficient support strength of the receiving cavity 2. In this embodiment, the openings 21 are designed to be oppositely arranged on the side wall of the receiving cavity 2, further reducing the weight of the test tube rack body.

[0040] In a more preferred embodiment, columnar support ribs 4 are formed between adjacent receiving cavities 2, and the code scanning and recognition area 3 is located on the side surface of the columnar support ribs 4. In this embodiment, the columnar support ribs 4 as a whole present a vertical triangular prism shape. On the one hand, the outer side surface of the columnar support ribs 4 can be used as the code scanning and recognition area 3 for pasting barcodes or two-dimensional codes. On the other hand, it can provide structural support for the receiving cavities 2 and increase a certain mechanical strength.

[0041] In a more preferred embodiment, a weight-reducing cavity 41 is provided in the center of the columnar support ribs 4. In this embodiment, the shape of the weight-reducing cavity 41 is similar to and concentric with that of the columnar support ribs 4 and penetrates to the bottom of the columnar support ribs 4. Its function is to reduce the weight of the test tube rack body 1.

[0042] In a more preferred embodiment, an annular clamping member 5 is connected to the top of the receiving cavity 2. The test tube 100 can be inserted into the annular clamping member 5, and an elastic limiting member is provided on the annular clamping member 5. The initial inner diameter of the elastic limiting member is smaller than the outer diameter of the test tube 100. After the test tube 100 is inserted into the annular clamping member 5, its side wall is pressed by the elastic limiting member, so that the test tube 100 can be firmly fixed inside the receiving cavity 2. Without being subjected to a large mechanical impact, it can be ensured that the test tube 100 does not shake inside the receiving cavity 2. The elastic limiting member has a certain compression deformation space and can adapt to the limiting and fixing of test tubes 100 with different outer diameters, and there is no need to frequently replace annular clamping members 5 of different sizes.

[0043] In a more preferred embodiment, the annular clamping member 5 includes a clamping ring 51 installed at the opening of the receiving cavity 2, and the elastic limiting member is an elastic fin 52 extending from the clamping ring 51 towards the receiving cavity 2. In this embodiment, the clamping ring 51 is installed and fixed by being clamped at the opening of the receiving cavity 2. The elastic fin 52 can closely fit the outer side wall of the test tube 100 after the test tube 100 is inserted into the annular clamping member 5 and fix it in the center of the receiving cavity 2. In this embodiment, the elastic fins 52 are annularly distributed at the lower part of the clamping ring 51. Four elastic fins 52 are distributed on a single clamping ring 51 and have a certain inclination angle. The inclination direction should be inclined inward from the side wall of the receiving cavity 2, so as to facilitate the insertion and placement of the test tube 100 and provide guidance. The opening diameter formed at the end of the elastic fin 52 should be smaller than the outer diameter of the test tube 100. As an alternative embodiment, annularly distributed elastic protrusions or annular protrusions can be provided on the inner side wall of the clamping ring 51, and the contact fixation of the test tube 100 can also be achieved.

[0044] In a more preferred embodiment, the top of the snap ring 51 has a snap 53, and the top side of the receiving cavity 2 has an opening two 22 that cooperates with the snap 53. The cooperation between the snap 53 and the opening two 22 allows for convenient pressing and installation when installing the snap ring 51. When disassembling, simply press the snap 53 to disengage it from the opening two 22 to remove the annular clip 5.

[0045] In a more preferred embodiment, a positioning groove 23 is provided at the top of the receiving cavity 2, and positioning protrusions 54 that cooperate with the groove 23 are distributed on the top of the snap ring 51. In this embodiment, the number of positioning protrusions 54 is three, and they are evenly distributed in a ring on the top of the snap ring 51. Their cooperation with the positioning groove 23 can position and limit the snap ring 51, preventing it from rotating, and further preventing the test tube 100 from rotating. Also, the cooperation between the positioning protrusions 54 and the positioning groove 23 enables the snap 53 of the annular clip 5 to accurately engage with the opening two 22 during installation.

[0046] In a more preferred embodiment, the bottom of the receiving cavity 2 has a positioning depression 24. In this embodiment, the positioning depression 24 is a circular pit provided at the bottom of the receiving cavity 2, and its outer dimensions are adapted to the bottom of the test tube 100. This positioning depression 24 can cooperate with the annular clip 5 to limit and fix the bottom and top of the test tube 100 respectively.

[0047] In a more preferred embodiment, a chute 11 is connected to the bottom of the bracket body 1, and a bead snap 12 is provided at the front end of the bracket body 1. Above the bead snap 12, a position stop 13 is connected to the front end connection position of the bracket body 1. With the arrangement of the chute 11, the drawer for installing the bracket body 1 also has a corresponding chute, enabling the entire bracket body 1 to be conveniently installed and disassembled in a sliding manner. A slot that cooperates with the bead snap 12 is also provided on the drawer. When installing and fixing the bracket body 1, simply push the bracket body 1 into place using the chute 11, and the bead snap 12 will snap into the cooperating slot. When disassembling, press again to pop the bead snap 12 out, and then pull the bracket body 1 out through the chute 11. The position stop 13 cooperates with an infrared sensor provided on the drawer to detect whether the bracket body 1 is installed in place. When the bracket body 1 is pushed in and installed in place, the position stop 13 will cause the infrared sensor to generate a signal indicating installation in place for external systems to recognize.
