Description

Technical Field

[0001] This utility model relates to the field of chemiluminescence detection technology, specifically to a chemiluminescence imaging instrument. Background Technology

[0002] Chemiluminescence imaging, as a highly sensitive detection method, is widely used in biomedicine, molecular diagnostics, and drug development, playing a particularly important role in experiments such as protein blotting and nucleic acid detection. The core principle of chemiluminescence imaging is to detect the light signals released by a sample during a chemical reaction, thereby enabling qualitative and quantitative analysis of the target substance.

[0003] In existing technologies, chemiluminescence imaging instruments typically consist of a housing, an imaging module, and a light source assembly. However, conventional housings are designed with open operating ports for easy sample placement. In practical use, external light can easily penetrate through these ports, leading to increased background noise, which significantly impacts the detection sensitivity of weak chemiluminescence signals. Furthermore, most chemiluminescence imaging instruments employ a single-sided or asymmetrical light source assembly layout, resulting in uneven light intensity distribution on the sample surface. This can easily produce shadows or light spots during imaging, affecting the accuracy of quantitative analysis. Utility Model Content

[0004] Based on the above description, this utility model provides a chemiluminescence imaging instrument, which aims to solve the problems of existing chemiluminescence imaging instruments being easily affected by external light intrusion, resulting in poor detection sensitivity and uneven light intensity distribution on the sample surface due to the layout of the light source components.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A chemiluminescence imaging instrument, comprising:

[0007] A housing assembly includes a housing having a receiving cavity and a dark cavity, the receiving cavity communicating with the dark cavity through at least one lens hole;

[0008] At least one camera is disposed within the receiving cavity, and each camera corresponds to one lens aperture, with the lens of the at least one camera facing the lens aperture;

[0009] A sample carrier assembly is disposed within the dark cavity. The sample carrier assembly includes a tray and an illumination element. The illumination element is configured as at least one pair, with each pair of illumination elements symmetrically arranged about the center line of the tray. The illumination element includes a light source.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the housing assembly includes a hinged door connected to the housing, the hinged door corresponding to the dark cavity.

[0012] Furthermore, an opening / closing detection element is provided inside the dark cavity.

[0042] For example, the light source 321 can be an LED white light or the like. The center line of the tray 31 is formed by connecting the midpoints of the two long sides of the tray 31.

[0043] In this embodiment, the dark cavity 112 provides a light-proof environment for the sample, and the camera 20 inside the receiving cavity 111 captures the chemiluminescence signal of the sample in the dark cavity 112 through its lens aperture. Each pair of illumination elements 32 is symmetrically distributed around the center line of the tray 31, ensuring uniform illumination of the sample by the light source 321 and reducing imaging shadows. This separation design between the dark cavity 112 and the receiving cavity 111 effectively isolates external light interference, ensuring high-sensitivity detection of the chemiluminescence signal. Furthermore, the symmetrical arrangement of the light sources 321 improves illumination uniformity and avoids imaging distortion caused by differences in light intensity.

[0044] Reference Figures 1 to 2 As shown, in some embodiments, the housing assembly 10 includes a hinged door 12 connected to the housing 11, and the hinged door 12 corresponds to the cavity 112.

[0045] For example, the hinged door 12 is rotatably connected to the housing 11.

[0046] In this embodiment, the closed flap 12 can maintain the airtightness of the dark cavity 112, thereby preventing light leakage from affecting imaging.

[0047] In some embodiments, the dark cavity 112 is provided with an opening and closing detection element 121.

[0048] For example, the opening / closing detection element 121 can be a distance sensor or a limit switch, etc.

[0049] In this embodiment, the operation of the camera 20 can be paused when the flip door 12 is not fully closed, ensuring that the dark cavity 112 is always in a sealed state, preventing light pollution caused by misoperation, and improving the reliability of the results.

[0050] Reference Figure 1 As shown, in some embodiments, a sealing strip 122 is provided between the housing 11 and the hinged door 12.

[0051] For example, the sealing strip 122 can be made of an elastic material, such as silicone.

[0058] In this embodiment, the light source 321 is fixed to the side wall of the dark cavity 112 by the mounting plate 322 to ensure that the illumination angle is fixed and to avoid optical path deviation caused by the offset of the light source 321.

[0059] Reference Figures 1 to 2 As shown, in some embodiments, the chemiluminescence imaging instrument includes a cooling fan 40, which is disposed in the receiving cavity 111. The housing 11 has a plurality of heat dissipation holes 113 corresponding to the cooling fan 40, and the air inlet end of the cooling fan 40 faces the plurality of heat dissipation holes 113.
