Technical Field
[0001] This utility model relates to the field of single-use reagent strip technology, and in particular to a reaction carrier module for chemiluminescent single-use reagent strips. Background Technology
[0002] Chemiluminescence immunoassay (CLIA) is a highly sensitive detection technology based on chemiluminescence reactions, widely used in clinical diagnostics, biomedical research, and environmental monitoring. In chemiluminescence detection, the reagent strip is the key reaction carrier, used to load samples and reagents for the chemiluminescence reaction. To achieve automated and high-throughput detection, a reaction carrier module capable of precisely controlling the movement of the reagent strip and reaction conditions is needed. Traditional chemiluminescence detection equipment typically employs fixed or semi-automated reaction carrier designs, which have limitations in practical applications. In recent years, with the development of automation and precision mechanical manufacturing technologies, more intelligent and automated reaction carrier modules have emerged, improving detection efficiency and accuracy.
[0003] The position detection accuracy of the existing device is insufficient. The photoelectric switch in the existing device may cause unstable detection signal due to ambient light interference or insufficient sensitivity of the photoelectric switch itself, making it impossible to accurately determine the position of the reaction carrier module.

The photoelectric switch adopts a non-contact detection method, avoiding mechanical wear and extending the service life of the equipment. The optocoupler baffle achieves precise control of the position of the reaction carrier module by blocking or removing the signal of the photoelectric switch, ensuring accurate stopping and starting at the predetermined position. The design is simple, the operation is reliable, and it can effectively trigger the photoelectric switch signal to achieve precise position control.

The single-use card strip reaction carrier module contains the single-use card strip body, which can provide a stable loading platform for the single-use card strip. The heating film provides the reaction temperature for the reagent card strip, ensuring the accuracy and reliability of the chemiluminescence reaction. The single-use card strip body, as the carrier of the chemiluminescence reaction, ensures the smooth progress of the reaction. The single-use design avoids cross-contamination and improves the accuracy and safety of detection.
[0013] As a further improvement to the above solution, a drag chain is provided at the top of the reaction carrier running fixed block module. The drag chain is located at the top of the reaction carrier running linear guide rail, and the rear end of the drag chain is connected to the surface of the support frame for transmission.
[0014] Through the above technical solutions, the cable chain provides protection for the heating film wire, preventing the wire from being worn or damaged during movement, extending the service life of the equipment.

[0030] The output end of the stepper motor 1 is connected to the top of the synchronous pulley 6 for transmission.
[0031] There are two synchronous pulleys 6, and the surfaces of the two synchronous pulleys 6 are connected by a synchronous belt.
[0032] The right end of the reaction carrier running fixed block module 10 is fixedly connected to the reaction carrier running linear guide rail 3.
[0033] The top of the reaction carrier running fixed block module 10 is fixedly connected to a support frame 11, and the top of the support frame 11 is fixedly connected to a single-use card strip reaction carrier module 8.
[0034] The single-use card strip reaction carrier module 8 consists of a metal reaction carrier and a heating film, and the single-use card strip body 9 is placed inside the single-use card strip reaction carrier module 8.
[0035] A drag chain 2 is provided at the top of the reaction carrier running fixed block module 10. The drag chain 2 is located at the top of the reaction carrier running linear guide rail 3, and the rear end of the drag chain 2 is connected to the surface of the support frame 11 for transmission.
[0036] The implementation principle of a reaction carrier module for a chemiluminescent single-use reagent strip in this embodiment is as follows: the output of a stepper motor provides power to the reaction carrier module through a synchronous pulley and a synchronous belt. Precise control of the stepper motor ensures that the reaction carrier module can move precisely in a straight line along a linear guide. Two synchronous pulleys are connected by a synchronous belt to ensure stable power transmission, reduce motion errors, and improve the stability and accuracy of the motion. A photoelectric switch is used to detect the position of the reaction carrier module, and an optocoupler baffle achieves precise control of the reaction carrier module's position by blocking or removing the signal from the photoelectric switch. When the optocoupler baffle is removed, the photoelectric switch detects a signal, the stepper motor starts, and the reaction carrier module moves along the linear guide rail. When the optocoupler baffle is blocked, the photoelectric switch does not detect a signal, the stepper motor stops, and the reaction carrier module stops at the predetermined position. The reaction carrier running fixing block module fixes the reaction carrier module and connects to the linear guide rail, ensuring the stability and straightness of the reaction carrier module during movement. The reaction carrier running linear guide rail provides precise guidance, ensuring that the reaction carrier module moves in a straight line, improving the stability and accuracy of movement. The single-use card strip reaction carrier module contains the single-use card strip body, which provides the reaction temperature to the reagent card strip through a heating film. The heat generated by the heating film is conducted to the reagent card strip through the metal reaction carrier, ensuring that the reagent card strip carries out the chemiluminescence reaction at a suitable temperature. The support frame provides stable support for the single-use card strip reaction carrier module, ensuring the stability of the reaction carrier module during operation. The drag chain is set at the top of the reaction carrier running linear guide rail, and the rear end is connected to the surface of the support frame for transmission, providing protection for the heating film wire, preventing the wire from being worn or damaged during movement, and extending the service life of the equipment.
