Description

Technical Field

[0001] The present invention relates to the technical field of optical instruments, and more specifically, to an optical instrument based on multifunctional fluorescence chemiluminescence imaging. Background Art

[0002] A fluorescence chemiluminescence imaging system is a precision instrument for detecting fluorescence and chemiluminescence signals of biological and chemical samples. During fluorescence imaging, it excites the sample with excitation light of a specific wavelength; chemiluminescence imaging utilizes the spontaneous luminescence of chemical reactions. Subsequently, the optical system collects the signals, and a high-sensitivity detector (such as a CCD or CMOS) converts the optical signals into electrical signals, which are then processed by software to present images.

[0003] Chinese Patent Application No. CN218067653U discloses an optical instrument based on multifunctional fluorescence chemiluminescence imaging, which specifically belongs to the field of optical instruments. The instrument includes a main body of the instrument, on one side of which there is a placement groove, one side of the groove is connected to a power cord, and one end of the power cord is fixedly connected to a lithium battery; on the other side, an LED light strip is fixedly connected. One side of the placement groove is rotatably connected to a groove cover, and there are two moving openings on the groove cover. A button is slidably connected in the middle of the moving opening, one end of the button is fixedly connected to a slider, the bottom of the slider is connected to a first spring, and the bottom of the spring is fixedly connected to a moving box (one side of the moving box is fixed to the groove cover). This technical solution increases the power storage structure and portability of the instrument, improves the use effect, and has practicality.

[0004] During the fluorescence chemiluminescence imaging detection process, the chamber door needs to tightly seal the sample chamber to construct a dark or low-light environment, which is crucial for ensuring the accuracy and sensitivity of the detection. Because once external stray light enters, it will significantly increase the background noise and interfere with the detection of weak fluorescence or chemiluminescence signals, resulting in deviation of the results. Therefore, the sealing performance of the sample chamber is of great importance. The existing sealing of the sample chamber mainly relies on the tight sealing of a fixedly connected gasket and the chamber door. However, the gasket is prone to aging and deformation, and after the chamber door is closed, the specific performance of the gasket is not easy to observe, and the sealing condition inside the sample chamber is also not easy to judge. It is very difficult for users to intuitively judge the sealing condition of the sample chamber.

[0005] Therefore, the present invention proposes an optical instrument based on multifunctional fluorescence chemiluminescence imaging, aiming to solve the above problems. Summary of the Invention

[0031] Example 1. Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , an optical instrument based on multifunctional fluorescence chemiluminescence imaging, including a fluorescence chemiluminescence imager 1. A chamber door 2 is movably installed at the lower position of the fluorescence chemiluminescence imager 1. An encapsulation board 6 is movably installed inside the chamber door 2. The encapsulation board 6 is located directly in front of the sample chamber 4. A sealing gasket 7 is fixedly connected to the side position of the encapsulation board 6. The sealing gasket 7 is located between the encapsulation board 6 and the sealing frame 8 to enhance the sealing performance. A sample chamber 4 is opened at the lower position of the fluorescence chemiluminescence imager 1. A sealing frame 8 is fixedly connected to the front position of the sample chamber 4. The sealing gasket 7 is movably installed with the sealing frame 8. When the encapsulation board 6 moves forward, the sealing gasket 7 comes into contact with the sealing frame 8.

[0032] The chamber door 2 is movably installed with the fluorescence chemiluminescence imager 1 through a hinge 3, so that the chamber door 2 can be easily rotated outwards. The sealing gasket 7 on the side of the encapsulation board 6 is in sealed contact with the sealing frame 8.

[0033] A plurality of connecting frames 10 are fixedly connected to the encapsulation board 6. The connecting frames 10 are located outside the sealing frame 8. A plurality of telescopic brackets 9 are fixedly connected to the inner side position of the chamber door 2. The positions of the connecting frames 10 correspond to the positions of the telescopic brackets 9, so that the telescopic brackets 9 and the connecting frames 10 are on the same horizontal line.

[0034] A through hole is opened in the connecting frame 10, and a screw 12 is movably installed in the through hole. One end of the screw 12 is fixedly connected to a limiting plate 13. When the telescopic bracket 9 moves backward, and then by rotating, the screw 12 is disengaged from the screw hole on the connecting frame 10, so that the limiting plate 13 and the screw 12 can be easily removed from the telescopic bracket 9. The limiting plate 13 is located inside the telescopic bracket 9.

[0035] The connecting frame 10 is provided with screw holes, and the other end of the screw rod 12 is fixedly connected to the screw holes of the connecting frame 10. A telescopic spring 11 is sleeved on the screw rod 12. Through compression, the telescopic spring 11 can push the connecting frame 10 to move outward, thereby pushing the encapsulation plate 6 to move outward. The telescopic spring 11 is located between the telescopic bracket 9 and the connecting frame 10.

[0036] Steps of using the present invention: When this optical instrument is in use, the encapsulation plate 6 is located outside the sealing frame 8, the sealing gasket 7 is located between the encapsulation plate 6 and the sealing frame 8. A plurality of connecting frames 10 fixedly connected to the encapsulation plate 6 are pushed outward by the telescopic spring 11, so that the encapsulation plate 6 and the sealing gasket 7 on the side extrude the sealing frame 8. The box door 2 wraps the encapsulation plate 6 inside. The edge position of the box door 2 fits with the outside position of the outer sealing frame 8 of the sample chamber 4, so that an additional outer sealing structure is provided outside the encapsulation plate 6, making the sealing effect of the sample chamber 4 better. When it is necessary to disassemble the encapsulation plate 6, rotate the limiting plate 13, so that the limiting plate 13 drives the screw rod 12 to rotate, and one end of the screw rod 12 is screwed out from the screw hole on the connecting frame 10. Then move the limiting plate 13 and the screw rod 12 backward in the telescopic bracket 9, so that the screw rod 12 and the limiting plate 13 are removed from the telescopic bracket 9, so that the connecting frame 10 is separated from the telescopic bracket 9, and the telescopic spring 11 between the two is synchronously separated, making the encapsulation plate 6 and the telescopic spring 11 easy to replace and maintain.

[0037] Embodiment 2, please refer to Figures 1 to 9 , which is different from Embodiment 1 in that a sample stage 5 is slidably connected in the sample chamber 4. The sample stage 5 expands and contracts in the sample chamber 4. A sliding frame 20 is fixedly connected to the bottom surface of the sample stage 5. The sample stage 5 drives the sliding frame 20 to move synchronously. One end of the connecting plate 22 is movably connected to the bottom surface of the encapsulation plate 6, and the connecting plate 22 is slidably connected to the sliding frame 20, so that when the encapsulation plate 6 is opened synchronously with the box door 2, the sample stage 5 can be pulled out through the connecting plate 22 and the sliding frame 20.

[0038] Sliding sleeves 18 are fixedly connected to both sides of the sample chamber 4. The sliding sleeves 18 are located on both sides of the sample stage 5. A plurality of rollers 19 are rotatably connected in the sliding sleeves 18. The rollers 19 are equidistantly distributed in the sliding sleeves 18. Both sides of the sample stage 5 are slidably connected in the sliding sleeves 18, and both sides of the sample stage 5 are rotatably connected to the rollers 19. When the sample stage 5 moves outward, the rollers 19 rotate synchronously, making the movement of the sample stage 5 smoother.

[0039] The sliding frame 20 is provided with a chute 21. One end of the connecting plate 22 is fixedly connected with a first connecting seat 23. The first connecting seat 23 slides in the chute 21 and can prevent it from disengaging from the chute 21. The first connecting seat 23 is slidably connected in the chute 21.

[0040] A second connecting seat 24 is fixedly connected to the lower position of the encapsulation board 6. The other end of the connecting plate 22 is provided with a through hole and is rotationally connected to the second connecting seat 24 through the through hole. The second connecting seat 24 passes upward through the corresponding through hole on the connecting plate 22 and is fixedly connected to the encapsulation board 6.

[0041] A fixing plate 27 is fixedly connected to the bottom surface of the sample chamber 4. A positioning rod 25 is fixedly connected to the fixing plate 27. Both ends of the positioning rod 25 are fixedly connected to the fixing plate 27 and the inner wall of the sample chamber 4 respectively. A sliding seat 28 is slidably connected to the positioning rod 25. A return spring 26 is sleeved on the positioning rod 25, and the return spring 26 is located between the fixing plate 27 and the sliding seat 28. When the sliding seat 28 moves, the return spring 26 will be compressed. The positioning rod 25, the return spring 26, the fixing plate 27 and the sliding seat 28 are located below the sample stage 5.

[0042] Steps of using the present invention: When this optical instrument is in use, after making the sample, open the box door 2, so that the box door 2 rotates laterally through the hinge 3, the box door 2 moves outwards, and the telescopic bracket 9 moves synchronously. When the limiting plate 13 contacts the telescopic bracket 9, the telescopic bracket 9 drives the limiting plate 13, and the limiting plate 13 drives the encapsulation board 6 to move synchronously through the screw rod 12 and the connecting frame 10. The encapsulation board 6 drives one end of the connecting plate 22 to move outwards through the second connecting seat 24. The first connecting seat 23 at the other end of the connecting plate 22 slides in the sliding groove 21 and pulls the sliding frame 20 outwards, so that the sliding frame 20 drives the sample stage 5 to move outwards. The sample stage 5 moves outwards in the sliding sleeve 18, and the rollers 19 corresponding to both sides of the sample stage 5 rotate synchronously. The sliding seat 28 moves synchronously on the positioning rod 25, so that the return spring 26 on the positioning rod 25 is compressed, thereby automatically extending the sample stage 5 outwards. When the sample stage 5 moves to a suitable position, place the sample on the sample stage 5; Then push the box door 2 in the reverse direction, so that the box door 2 and the encapsulation board 6 on the side of the box door 2 gradually approach the sealing frame 8. At this time, the elastic force of the return spring 26 is greater than the pressure exerted by the sliding seat 28. The second connecting seat 24 at one end of the connecting plate 22 moves synchronously with the encapsulation board 6. The first connecting seat 23 at the other end of the connecting plate 22 slides reversely in the sliding groove 21, and the sliding seat 28 moves reversely on the positioning rod 25, pushing the sample stage 5 reversely in the sliding sleeve 18. Then the encapsulation board 6 and the sealing gasket 7 are closed with the sealing frame 8 to cut off, thereby realizing the automatic contraction of the sample stage 5, so that when placing the sample, there is no need to manually drag the sample stage 5, improving the convenience of operation.

[0043] Example three, please refer to Figures 1 to 9, the difference from the basis of Embodiment 2 is that a photodetector 15 is fixedly connected to one side of the encapsulation board 6. The photodetector 15 detects the light source in the sample chamber 4. A buzzer 17 is fixedly connected to the other side of the encapsulation board 6. The buzzer 17 serves as a warning by beeping. An installation chamber 14 is provided on the encapsulation board 6. The buzzer 17 is fixedly connected in the installation chamber 14. The microcontroller 16 and the buzzer 17 are wrapped and protected by the outer box door 2. A microcontroller 16 is fixedly connected above the buzzer 17 in the installation chamber 14. The pins of the photodetector 15 pass through the encapsulation board 6 and are fixedly connected to the microcontroller 16. The photodetector 15 is arrayed on the inner side of the encapsulation board 6, and the photodetector 15 extends into the sample chamber 4.

[0044] Steps of using the present invention: When this optical instrument is in use, the buzzer 17 and the photodetector 15 are started. During sample detection, first open the box door 2. After the box door 2 is opened, the encapsulation board 6 is separated from the sample chamber 4, and external light sources enter the sample chamber 4. The photodetector 15 moves with the movement of the box door 2, so that the photodetector 15 is exposed to the external light source. The photodetector 15 transmits the signal to the microcontroller 16. After the microcontroller 16 determines the external light source, it starts the buzzer 17 connected by telecommunications and controls the buzzer 17 to beep softly, so as to test the photodetector 15 and the buzzer 17 in the external light source to determine whether they are operating normally. If the buzzer 17 does not beep, it means it is damaged and needs to be repaired or replaced in time. After the sample is placed on the sample stage 5, the box door 2 is closed and fixedly connected to the fluorescence chemiluminescence imager 1 through structures such as locks. At this time, after the encapsulation board 6 and the sealing frame 8 are sealed to each other, the sample chamber 4 should be in a black box state without external light sources when not working. After the photodetector 15 cannot detect external light sources, the buzzer 17 stops beeping at this time, indicating that the sealing state of the sample chamber 4 is good. If the buzzer 17 does not stop beeping, it means that the sealing effect of the box door 2 is poor and there are still external light sources entering. During the process of fluorescence chemical imaging, when the excitation light source emits light, the photodetector 15 detects the signal and synchronously starts the buzzer 17 to beep softly, so as to remind the staff that the internal is working, making it convenient to detect the sealing state in the sample chamber 4 and preventing external light sources from entering the interior, causing interference and affecting the accuracy of the results.
