Description

Technical Field

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

[0002] The fluorescence and chemiluminescence imaging system is a precision instrument used to detect 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 uses spontaneous luminescence from chemical reactions. Subsequently, the optical system collects the signal, and a highly sensitive detector (such as CCD, CMOS) converts the light signal into an electrical signal, which is then processed by software to present an image.

[0003] Chinese patent application number CN218067653U discloses an optical instrument based on multifunctional fluorescence chemiluminescence imaging, which specifically belongs to the field of optical instruments. The instrument includes an instrument body, one side of which is provided with a placement slot, one side of which is connected to a power cord, one end of which is fixedly connected to a lithium battery; the other side is fixedly connected to an LED light strip, one side of the placement slot is rotatably connected to a slot cover, and the slot cover has two movable openings, the middle of which is slidably connected to a button, 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 movable box (one side of the movable box is fixed to the slot cover). This technical solution increases the power storage structure and mobility convenience of the instrument, improves the use effect, and is practical.

[0004] During the fluorescence and chemiluminescence imaging detection process, the door of the chamber needs to tightly seal the sample chamber to create a dark or low-light environment. This is the key to ensuring detection accuracy and sensitivity. Once external stray light enters, it will significantly increase background noise, interfere with the detection of weak fluorescence or chemiluminescence signals, and cause deviation in the results. Therefore, the sealing of the sample chamber is crucial. The sealing of the existing sample chamber mainly relies on the tight sealing of the fixed sealing gasket and the chamber door. However, the sealing gasket is prone to aging and deformation. After the chamber door is closed, the specific performance of the sealing gasket is difficult to observe, and the sealing condition of the sample chamber is also difficult to judge. It is difficult for users to intuitively judge the sealing condition of the sample chamber.

[0047] The door 2 is movably mounted on the fluorescent chemiluminescence imager 1 via a hinge 3 , so that the door 2 can be easily rotated outwards, and the sealing gasket 7 on the side of the packaging plate 6 is in sealing contact with the sealing frame 8 .

[0048] Several connecting frames 10 are fixedly connected to the packaging plate 6, and the connecting frames 10 are located on the outer side of the sealing frame 8. Several telescopic brackets 9 are fixedly connected to the inner side of the box 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 located on the same horizontal line.

[0049] A through hole is provided 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. The limiting plate 13 moves backward on the telescopic bracket 9, and then rotates to disengage the screw 12 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.

[0050] A screw hole is provided on the connecting frame 10, and the other end of the screw 12 is fixedly connected to the screw hole of the connecting frame 10. A telescopic spring 11 is mounted on the screw 12. The telescopic spring 11 is compressed so that the telescopic spring 11 can push the connecting frame 10 outward to move, thereby pushing the packaging plate 6 outward. The telescopic spring 11 is located between the telescopic bracket 9 and the connecting frame 10.

[0051] The steps of using the present invention are as follows: when the optical instrument is in use, the packaging plate 6 is located at the outer side of the sealing frame 8, the sealing gasket 7 is located between the packaging plate 6 and the sealing frame 8, and the plurality of connecting frames 10 fixedly connected to the packaging plate 6 are pushed outward by the telescopic spring 11, so that the packaging plate 6 and the sealing gasket 7 on the side squeeze the sealing frame 8, and the box door 2 wraps the packaging plate 6 in the inner position, and the edge position of the box door 2 is in contact with the outer side of the sealing frame 8 outside the sample chamber 4, thereby providing another layer of outer sealing structure at the outer side of the packaging plate 6, so that the sealing effect of the sample chamber 4 is better;

[0052] When it is necessary to remove the packaging plate 6, the limiting plate 13 is rotated so that the limiting plate 13 drives the screw 12 to rotate, so that one end of the screw 12 is screwed out of the screw hole on the connecting frame 10, and then the limiting plate 13 and the screw 12 are moved backward in the telescopic bracket 9, so that the screw 12 and the limiting plate 13 are removed from the telescopic bracket 9, so that the connecting frame 10 is disengaged from the telescopic bracket 9, and the telescopic spring 11 between the two is disengaged synchronously, so that the packaging plate 6 and the telescopic spring 11 are easy to replace and maintain.

[0053] For example 2, please refer to Figures 1 to 9 , combined with the basis of Example 1, the difference is that a sample stage 5 is slidably connected to the sample chamber 4, the sample stage 5 is retracted in the sample chamber 4, the bottom position of the sample stage 5 is fixedly connected to the slide 20, the sample stage 5 drives the slide 20 to move synchronously, and the bottom position of the packaging plate 6 is movably connected to the connecting plate 22, and the connecting plate 22 is slidably connected to the slide 20, so that when the packaging 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 slide 20.

[0054] The two sides of the sample chamber 4 are fixedly connected with sliding sleeves 18, which are located on both sides of the sample stage 5. Several rollers 19 are rotatably connected in the sliding sleeves 18, and the rollers 19 are evenly distributed in the sliding sleeves 18. The two sides of the sample stage 5 are slidably connected in the sliding sleeves 18, and the two 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 more stable.

[0055] A slide groove 21 is provided on the slide 20, and one end of the connecting plate 22 is fixedly connected to a connecting seat No. 1 23. The connecting seat No. 1 slides in the slide groove 21 and can prevent it from detaching from the slide groove 21. The connecting seat No. 1 23 is slidably connected in the slide groove 21.

[0056] The lower position of the packaging plate 6 is fixedly connected to the No. 2 connecting seat 24. A through hole is opened at the other end of the connecting plate 22, and it is rotatably connected to the No. 2 connecting seat 24 through the through hole. The No. 2 connecting seat 24 passes upward through the corresponding through hole on the connecting plate 22 and is fixedly connected to the packaging plate 6.

[0057] A fixing plate 27 is fixedly connected to the bottom surface of the sample chamber 4, and a positioning rod 25 is fixedly connected to the fixing plate 27. The two 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 slide 28 is slidably connected to the positioning rod 25. A return spring 26 is mounted on the positioning rod 25, and the return spring 26 is located between the fixing plate 27 and the slide 28, so that when the slide 28 moves, the return spring 26 will be compressed. The positioning rod 25, the return spring 26, the fixing plate 27 and the slide 28 are located below the sample stage 5.

[0058] The steps of using the present invention are as follows: when the optical instrument is in use, after the sample is prepared, the box door 2 is opened, so that the box door 2 rotates to the side through the hinge 3, the box door 2 moves outward, and the telescopic bracket 9 moves synchronously. When the limiting plate 13 and the telescopic bracket 9 contact each other, the telescopic bracket 9 drives the limiting plate 13, and the limiting plate 13 drives the packaging plate 6 to move synchronously through the screw 12 and the connecting frame 10. The packaging plate 6 drives one end of the connecting plate 22 to move outward through the No. 2 connecting seat 24, and the No. 1 connecting seat 23 at the other end of the connecting plate 22 slides in the slide groove 21 and pulls the slide 20 outward, so that the slide 20 drives the sample stage 5 to move outward, and the sample stage 5 moves outward in the sliding sleeve 18. The rollers 19 corresponding to the positions on both sides of the sample stage 5 rotate synchronously, and the slide 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 outward. When the sample stage 5 moves to the appropriate position, the sample is placed on the sample stage 5; Then the box door 2 is pushed in the reverse direction, so that the box door 2 and the packaging plate 6 on the side of the box door 2 gradually approach the sealing frame 8. At this time, the elastic force of the reset spring 26 is greater than the pressure applied by the slide 28. The No. 2 connecting seat 24 at one end of the connecting plate 22 moves synchronously with the packaging plate 6, and the No. 1 connecting seat 23 at the other end of the connecting plate 22 slides in the reverse direction in the slide groove 21. The slide 28 moves in the reverse direction on the positioning rod 25, pushing the sample stage 5 in the reverse direction in the sliding sleeve 18. Then the packaging plate 6 and the sealing gasket 7 are closed with the sealing frame 8 and cut off, thereby realizing the automatic retraction of the sample stage 5, so that when placing the sample, there is no need to manually drag the sample stage 5, thereby improving the convenience of operation.

[0059] For example three, please refer to Figures 1 to 9 , combined with the basis of Example 2, the difference is that a photodetector 15 is fixedly connected to one side of the packaging board 6, and the photodetector 15 detects the light source in the sample chamber 4. A buzzer 17 is fixedly connected to the other side of the packaging board 6, and the buzzer 17 serves as a warning. An installation compartment 14 is provided on the packaging board 6, and the buzzer 17 is fixedly connected in the installation compartment 14. The microcontroller 16 and the buzzer 17 are wrapped and protected by the outer box door 2. The microcontroller 16 is fixedly connected to the installation compartment 14 at a position above the buzzer 17. The pins of the photodetector 15 pass through the packaging board 6 and are fixedly connected to the microcontroller 16. The photodetector 15 array is located on the inner side of the packaging board 6, and the photodetector 15 extends into the sample chamber 4.

[0060] The use steps of the present invention are as follows: when the optical instrument is in use, the buzzer 17 and the photodetector 15 are started. When testing a sample, the box door 2 is opened first. After the box door 2 is opened, the packaging plate 6 and the sample chamber 4 are separated from each other, and an external light source enters the sample chamber 4. The photodetector 15 moves with the movement of the box door 2, thereby exposing the photodetector 15 to the external light source. The photodetector 15 transmits a signal to the microcontroller 16. After the microcontroller 16 determines that the external light source is present, it starts the buzzer 17 connected to the telecommunications system and controls the buzzer 17 to beep softly, thereby testing 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 indicates that 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. After being fixedly connected to the fluorescent chemiluminescence imager 1 through structures such as locks, the packaging plate 6 and the sealing frame 8 are sealed with each other. When the sample chamber 4 does not start working, it should be in a black box state with no external light source. After the photodetector 15 cannot detect the external light source, the buzzer 17 stops beeping, 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 external light sources are still entering. During the fluorescent chemical imaging process, when the excitation light source emits light, the photodetector 15 detects the signal and synchronously starts the buzzer 17 to beep softly, thereby reminding the staff that work is in progress inside, making the sealing state in the sample chamber 4 easy to detect, and avoiding external light sources from entering the interior, causing interference and affecting the accuracy of the results.
