Embodiment Construction
[0044] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0045] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

The invention relates to a cleaning module; and the cleaning module is connected with a liquid extracting pipe and a liquid injecting pipe and used for injecting cleaning liquid in a reaction cup or extracting waste liquid. The cleaning module comprises a needle sleeve, a needle base rotationally arranged in the needle sleeve in a sleeved mode, a liquid extracting needle for extracting the waste liquid and inserted in the needle base and connected with a liquid extracting pipe, and a liquid injecting needle for injecting in the cleaning liquid and inserted in the needle base and connected witha liquid injecting pipe; an output port of the liquid injecting needle corresponds to the outer wall surface of the liquid extracting needle; the cleaning liquid flows into the reaction cup along theouter wall surface of the liquid extracting needle by the output port of the liquid injecting needle; and the cleaning module is simple in structure and convenient to operate, and can improve the cleaning effect.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a cleaning component, a cleaning mechanism including the cleaning component, and a chemiluminescence detector including the cleaning mechanism. Background technique [0002] Chemiluminescent immunoassay is an in vitro detection and analysis technology that combines antigen-antibody immune reaction and luminescent reaction. It is based on immunology theory, uses luminescent markers as trace signals, and detects various markers by collecting light signals. , which has the advantages of high sensitivity, low non-specific adsorption and high accuracy. With the rapid development of biomedical equipment, certain conditions have been met to realize the full automation of chemiluminescence detectors. [0003] In general, chemiluminescent detectors based on biochemiluminescent immunoassays have become well-established medical diagnostic devices. However, general-purpose chem...
