Description

Technical Field

[0001] The utility model relates to a chemiluminescent immunoassay analyzer, in particular to an incubation detection integrated system. Background Art

[0002] Chemiluminescent immunoassay is a new type of labeled immunoassay technology that combines chemiluminescence or bioluminescence with immune response to detect trace amounts of antigens or antibodies. Chemiluminescent immunoassay technology is more environmentally friendly and safer than traditional radioimmunoassay, and has higher sensitivity and a wider detection range than enzyme-linked immunosorbent assay. Chemiluminescent immunoassay is widely recognized for its environmentally friendly, rapid, and accurate characteristics, and has become the main means of clinical immunodiagnosis.

[0003] In the physical structure of the chemiluminescent immunoassay analyzer, many modules such as filling, mixing, incubation, washing and detection are involved. In traditional analyzers, each module is usually independently arranged at different stations, which has the defects of bulky volume and low detection efficiency. With the continuous development of technology, in order to improve the detection efficiency, some systems combining multiple functional modules have appeared on the market, such as the Chinese patent document with announcement number CN217156539U, which records an incubation detection module, which includes a supporting shell, and a tray with a cylindrical structure is rotatably installed inside the supporting shell. By setting the incubation hole in the middle area of ​​the tray and separately setting the detection station at the edge of the tray, the incubation and detection functions are integrated into one module. Although this module reduces the volume of the overall structure and improves the compactness of the system, it will complicate the structure of the module and increase the moving stroke of the local gripper. Therefore, the incubation structure needs to be further optimized. Utility Model Content

[0024] The utility model is further described below in conjunction with embodiments and drawings.

[0025] like Figure 1 and 4 As shown, an incubation and detection integrated system includes a cabin 1, a tray 2 is rotatably installed inside the cabin 1, and a driving mechanism 3 capable of driving the tray 2 to rotate is provided at the bottom of the cabin 1. The tray 2 is constructed as a cylindrical structure, and is provided with a plurality of circles of incubation holes 2a distributed in a circular array, and the incubation holes 2a are used to place reaction cups b. Since the incubation and detection integrated system provided in this embodiment is a compact and miniaturized system, in this embodiment, two circles of incubation holes 2a are arranged on the tray 2, wherein at least one of the incubation holes 2a located in the outermost circle is defined as a detection hole position 2b. A detection window 2c is provided on the side of the tray 2, which is opposite to and connected to the lower part of the detection hole position 2b, and the detection window 2c exposes the lower part of the reaction cup b located in the detection hole position 2b. In combination with Figure 3 As shown, the side of the chamber 1 is provided with an assembly notch 1a, and the detection module 4 is fixedly installed at the position of the assembly notch 1a. The light-emitting detection element 4a of the detection module 4 faces the inside of the chamber 1 and is arranged at the same height as the detection window 2c. When the reaction cup b to be tested on the detection hole 2b stops at the position of the detection module 4, the light-emitting detection element 4a can face the detection window 2c of the detection hole 2b, and the light-emitting detection element 4a can work to complete the analysis and detection.

[0026] Based on the above structural design, the outermost incubation holes 2a are directly used as the detection holes 2b, and the detection window 2c is set at the position corresponding to the detection hole 2b on the side of the tray 2. Without the need for additional layout and setting of detection stations, the two functions of incubation and detection can be more reasonably integrated into one module, which has the advantages of simple structure, high integration and compact product. At the same time, it can also optimize the moving stroke of the gripper in the analyzer and improve the detection efficiency.

[0027] Further, such as Figure 2 and 3 As shown, a support step a is provided on the upper part of the incubation hole 2a and the detection hole 2b. The support step a can enable the reaction cup b to be stably placed in the detection hole 2b, thereby improving the stability of the detection.

[0028] Please refer to Figure 3 and 4 In this embodiment, among the incubation holes 2a located in the outermost circle, there are four detection holes 2b, and the four detection holes 2b are evenly distributed on the circumference and radially symmetrical with respect to the two detection holes 2b. With such a design, the number of detection holes 2b is increased through reasonable layout, and at the same time, the moving stroke of the gripper in the analyzer is conveniently optimized, further improving the detection efficiency.

[0029] Re-attend Figure 2 and 3 , a mounting shaft 2d passing through the cabin 1 downward is provided at the bottom of the tray 2, and an annular support portion 1b extending upward is provided at the bottom of the cabin 1, and the mounting shaft 2d is rotatably assembled in the annular support portion 1b through a bearing b. In this embodiment, the driving mechanism 3 is a motor, and the output shaft 3a of the motor is coaxially sleeved at the bottom of the mounting shaft 2d. The output shaft 3a of the motor rotates, which can directly drive the tray 2 to rotate, and has the technical advantages of high rotation accuracy and strong stability, and is particularly suitable for equipment with high position accuracy requirements such as chemiluminescence immunoassay analyzers. At the same time, such a driving mechanism has a simple structure, reduces the probability of mechanical failure, and is convenient for maintenance.

[0030] In this embodiment, the number of bearings b is two, which can further reduce the friction loss between the mounting shaft 2d and the annular support portion 1b and protect the components from damage.

[0031] For example Figure 3 As shown, the lower part of the mounting shaft 2d is fixedly sleeved with a positioning code disc 5, which is coaxially arranged with the mounting shaft 2d. With such a design, the positioning code disc 5 can identify the rotation angle of the tray 2, so that each hole position on the tray 2 can rotate one by one according to the preset center angle.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
