Description

Technical Field

[0001] The utility model relates to the technical field of immunoassay analyzers in medical devices, and particularly relates to a test tube rack for an immunoassay analyzer. Background Art

[0002] Chemiluminescent labeled immunoassay, also known as chemiluminescent immunoassay (CLIA), is an immunoassay method that directly labels antigens or antibodies with chemiluminescent agents. A chemiluminescent immunoassay analyzer comprises two parts, namely an immune reaction system and a chemiluminescent 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 (chemiluminescent immunoassay) or an antibody (immunochemiluminescent assay), or an enzyme acts on a luminescent substrate.

[0003] In an immunoassay analyzer, there is a dedicated push-pull drawer for storing test tubes. In this drawer, the test tubes are neatly arranged in a test tube rack. Generally, there are multiple test tube racks in a dedicated drawer. Multiple test tubes are placed on each test tube rack, and each test tube needs to be uniformly numbered and uniquely identified. The test tube rack for storing test tubes should be able to stably support the test tubes without shaking, be convenient for taking and placing, and at the same time, it should also be convenient for information-based identification and management of the test tube storage positions.

[0004] Through retrieval, there are technical solutions regarding test tube racks in immunoassay analyzers disclosed in the prior art at present. For example, the utility model patent announcement document with the publication number "CN203881788U" and the name "Test Tube Rack for Chemiluminescent Immunoassay Analyzer". It discloses a test tube rack for a chemiluminescent immunoassay analyzer, including a test tube rack body. A test tube placement groove is opened on the test tube rack body. A grasping part is arranged at the front end of the test tube rack body, and a positioning element is also arranged on the test tube rack body.

[0021] 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 of 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.

[0022] A test tube rack for an immunoassay analyzer includes a bracket body 1. There is a straight row array with an accommodation cavity 2 on the bracket body 1. The side part of the bracket body 1 includes a code scanning and recognition area 3 corresponding to the accommodation cavity 2, and the code scanning and recognition area 3 is inclined. In this embodiment, the test tubes 100 are neatly placed in a straight row in the accommodation cavity 2, and the shape of the accommodation cavity 2 is adapted to the outer shape of the test tubes 100. Each accommodation cavity 2 has a corresponding code scanning and recognition area 3, and a bar code or QR code for recognition can be pasted on the code scanning and recognition area 3. After the scanning device scans the code scanning and recognition area 3, the corresponding information of the corresponding test tube can be obtained. Therefore, unified information management can be carried out for each test tube 100, and the recognition is unique. And the code scanning and recognition area 3 is inclined to obtain a better scanning and recognition effect. In this embodiment, the code scanning and recognition area 3 is as shown in Figure 1 , as a whole, is a rectangular area, inclined at a certain angle towards the accommodation cavity 2. When the scanning device passes through the code scanning and recognition area 3, the inclined setting makes the scanning faster and more accurate.

[0023] In a more preferred embodiment, the accommodation cavity 2 has an opening 21 on one side of the code scanning and recognition area 3, and the code scanning and recognition area 3 is arranged on the planar area adjacent to the opening 21. The opening 21 makes the side wall of the accommodation 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 relatively light, this design structure will not cause the problem that the supporting strength of the accommodation cavity 2 is insufficient. In this embodiment, the opening 21 is designed to be oppositely arranged on the side wall of the accommodation cavity 2, further reducing the weight of the test tube rack body.

[0024] In a more preferred embodiment, a columnar support rib 4 is formed between adjacent accommodation cavities 2, and the code scanning and recognition area 3 is located on the side surface of the columnar support rib 4. In this embodiment, the columnar support rib 4 as a whole presents a vertical triangular prism shape. On the one hand, the outer side surface of the columnar support rib 4 can be used as the code scanning and recognition area 3 for pasting barcodes or two-dimensional codes, and on the other hand, it can provide structural support for the accommodation cavity 2 and increase a certain mechanical strength.

[0025] In a more preferred embodiment, a weight-reducing cavity 41 is provided in the center of the columnar support rib 4. In this embodiment, the shape of the weight-reducing cavity 41 is similar to and concentric with that of the columnar support rib 4 and penetrates to the bottom of the columnar support rib 4, and its function is to reduce the weight of the test tube rack body 1.

[0026] In a more preferred embodiment, an annular clamping member 5 is connected to the top of the accommodation 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, and 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, the side wall of the test tube 100 is pressed by the elastic limiting member, so that the test tube 100 can be firmly fixed inside the accommodation cavity 2, and it can be ensured that the test tube 100 does not shake inside the accommodation cavity 2 without being subjected to a large mechanical impact. The elastic limiting member has a certain compression deformation space and can adapt to the limiting fixation of test tubes 100 with different outer diameters without the need to frequently replace annular clamping members 5 of different sizes.

[0027] In a more preferred embodiment, the annular clamping member 5 includes a clamping ring 51 installed at the opening of the accommodation cavity 2, and the elastic limiting member is an elastic fin 52 extending from the clamping ring 51 into the accommodation cavity 2. In this embodiment, the clamping ring 51 is installed and fixed by being clamped at the opening of the accommodation cavity 2 to realize the installation and fixation of the entire annular clamping member 5. 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 to fix it in the center of the accommodation cavity 2. In this embodiment, the elastic fins 52 are annularly distributed at the lower part of the clamping ring 51, and four elastic fins 52 are distributed on a single clamping ring 51 and have a certain inclination angle, and the inclination direction should be inclined inward from the side wall of the accommodation cavity 2, so as to facilitate the insertion and placement of the test tube 100 and guiding. 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 realized.

[0028] In a more preferred embodiment, the top of the snap ring 51 has a snap buckle 53, and the top side of the receiving cavity 2 has an opening two 22 that cooperates with the snap buckle 53. The cooperation between the snap buckle 53 and the opening two 22 facilitates the pressing and installation of the snap ring 51 during installation. When disassembling, simply press the snap buckle 53 to disengage it from the opening two 22 to remove the annular clip 5.

[0029] 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, which 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 the snap ring 51 from rotating and further preventing the test tube 100 from rotating. Moreover, the cooperation between the positioning protrusions 54 and the positioning groove 23 enables the snap buckle 53 of the annular clip 5 to accurately engage with the opening two 22 during installation.

[0030] 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 external 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.

[0031] In a more preferred embodiment, a sliding groove 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 flap 13 is connected to the front end connection position of the bracket body 1. With the arrangement of the sliding groove 11, the drawer for installing the bracket body 1 also has a corresponding sliding groove, 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 the sliding groove 11, and the bead snap 12 can be snapped into the cooperating slot. When disassembling, press again to pop out the bead snap 12, and then pull out the bracket body 1 through the sliding groove 11. The position flap 13 cooperates with an infrared sensor provided on the drawer to detect whether the bracket body 1 is installed in place.
