Description

Technical Field

[0001] The utility model relates to the technical field of chemiluminescence immunoassay, and more specifically, to a centrifugal device for a fully automatic chemiluminescence immunoassay analyzer. Background Technique

[0002] Luminescence immunoassay technology is an ultra-trace analysis method that combines luminescence analysis and immune reaction. It uses a chemical or bioluminescence system as an indicator to detect the specific binding between antigens and antibodies. This technology is widely used in medical diagnosis, biotechnology research, and clinical laboratories due to its high sensitivity and high specificity. In traditional fully automatic chemiluminescence immunoassay analyzers, a three-axis motion mechanism is usually used to achieve sample processing and the clamping of reaction tubes. Although this mechanism can achieve precise movement and positioning, after centrifugation, due to structural limitations, the removal of reaction tubes is often not convenient enough, requiring additional operation steps or manual intervention, which increases the complexity and time cost of operation. In addition, the existing centrifugal devices need to be manually disinfected after use to prevent cross-contamination and ensure the accuracy of experiments. This process is not only time-consuming and laborious, but may also lead to incomplete disinfection due to human factors, affecting the reliability of subsequent experimental results. There are also some biological reactions that need to be carried out under specific temperature conditions, which requires the luminescence immunoassay analyzer to have a temperature control function.

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0038] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0040] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] As described in the background art, in a traditional fully automatic chemiluminescence immunoassay analyzer, a three-axis motion mechanism is usually adopted to achieve sample handling and the clamping of reaction tubes. Although this mechanism can achieve precise movement and positioning, after centrifugation is completed, due to structural limitations, the removal of the reaction tubes is often not convenient enough, and additional operation steps or manual intervention are required, which increases the complexity of the operation and the time cost. In addition, the existing centrifugal devices need to be manually disinfected after use to prevent cross-contamination and ensure the accuracy of the experiment. This process is not only time-consuming and laborious, but also may lead to incomplete disinfection due to human factors, affecting the reliability of subsequent experimental results. There are also some biological reactions that need to be carried out under specific temperature conditions, which requires the chemiluminescence immunoassay analyzer to have a temperature control function. However, not all existing devices can provide precise temperature control, which may affect the efficiency and accuracy of some biological reactions.

[0042] To address the above problems, a centrifuge device for a fully automatic chemiluminescence immunoassay analyzer proposed in this application is provided. By arranging a telescopic component at the bottom of the connecting cylinder for placing reaction tubes on the rotating motor, after the liquid in the reaction tubes is centrifuged, the reaction tubes can be pushed upward through the telescopic component, causing the tops of the reaction tubes to extend out of the connecting cylinder, facilitating taking and reducing operation steps and manual intervention, thereby improving work efficiency. Through the disinfection component provided corresponding to the connecting cylinder, it is possible to achieve full-automatic disinfection of the entire interior of the centrifuge device, reducing the need for manual disinfection, lowering the risk of human operation errors and cross-contamination, and ensuring the safety and accuracy of experiments. By arranging the heating component, the temperature inside the centrifuge device can be controlled to meet the specific temperature requirements of certain biological reactions, improving the efficiency and accuracy of the reactions, and at the same time expanding the application scope of the device. The improvement in automation level and the precision of temperature control make the experimental conditions more stable and controllable, thus improving experimental efficiency and data quality. Due to the increased automation level of the device, the need for human intervention during the experiment is reduced, and the risk of experimental failure or inaccurate data caused by improper operation is lowered. The temperature control function of the device enables it to adapt to the requirements of more types of biological reactions, enhancing the versatility and applicability of the device. Since the reaction tubes are easy to take out after centrifugation, and the device can automatically disinfect and adjust the temperature, the work process in the laboratory becomes more smooth and coherent, reducing the time for experimental preparation and cleaning work.
