[0001] This utility model relates to the field of filling equipment technology, and in particular to an FOB buffer filling device. Background Technology

[0002] The fecal occult blood sample collector, also known as FOB, is of significant value in the diagnosis of gastrointestinal bleeding and is now often used as a screening indicator for the early diagnosis of gastrointestinal malignancies. During the manufacturing process, buffer solution needs to be added to the FOB dropper.

[0003] Existing FOB buffer filling equipment places multiple sets of FOB droppers on a tray rack to improve filling efficiency, and uses an electric drive mechanism to fill the batches of FOB droppers with the filling needle. However, while the filling needle is filling the first batch of FOB droppers, the subsequent FOB droppers are exposed to the air. During the filling process, the buffer solution may be contaminated by microorganisms, dust, or contaminants in the air, resulting in a decrease in filling quality and a certain cost loss. Therefore, this application proposes an FOB buffer filling device. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the background technology that when filling the first batch of FOB droppers with the filling needle, the later part of the FOB droppers will be exposed to the air, which may cause the filling buffer to be contaminated by microorganisms, dust or contaminants in the air or the equipment itself during the filling process, resulting in a decrease in filling quality and a certain cost loss. The invention proposes an FOB buffer filling device.

[0030] like Figure 1-3 As shown, the present invention proposes an FOB buffer filling device, including a base 1 and a frame 2 fixedly installed on the top of the base 1. A mounting frame 3 is fixedly installed on the frame 2, and a movable filling assembly is provided on the mounting frame 3. The filling assembly includes a mounting seat 7 installed on the mounting frame 3, and a cylinder 8 is fixedly installed on the mounting seat 7. The piston rod of the cylinder 8 is fixedly connected to a mounting plate 9. Multiple filling needles 10 are regularly arranged on the mounting plate 9. In this device, the filling needles 10 are arranged in two rows, and the filling needles 10 are connected to a peristaltic pump through a flexible tube. When the peristaltic pump works, it works in conjunction with the extension of the piston rod of the cylinder 8 to drive the mounting plate 9 to move downward, so that the buffer solution can flow out from the filling needles 10 for filling operation.

[0031] In addition, the moving parts in the movable filling assembly specifically include lead screws, servo motors, sliding blocks, etc. Since these are existing technologies and not closely related to this solution, they will not be described in detail here. The base 1 is located below the frame 2 and has a support plate 4. A box 5 is fixedly connected to the support plate 4. A tray fixture 6 is placed inside the box 5. Several FOB droppers are set on the tray fixture 6. The buffer solution flowing out of the filling needle 10 will enter the FOB dropper to complete the filling.

[0032] It is worth noting that an electric slide rail 11 is provided on the base 1, and a slider 12 is slidably installed on the electric slide rail 11. The slider 12 is fixedly connected to the support plate 4. By sliding the slider 12 back and forth in the electric slide rail 11, the support plate 4 can drive the tray fixture 6 to move and adjust, so that the filling needle 10 can complete the filling of all FOB droppers. A slot is opened on one side of the inner wall of the box body 5. One end of the tray fixture 6 is connected to a locking block that matches the slot. A rubber pad 13 is provided on the bottom inner wall of the box body 5 to contact the bottom end of the tray fixture 6. By using the locking block to lock into the slot, the tray fixture 6 can be further fixed in the box body 5, avoiding the shaking of the tray fixture 6 during the movement and adjustment process, which would affect the normal filling. A sealing door is hinged on one side of the box body 5. After the tray fixture 6 is placed, the sealing door is closed to maintain the seal.

[0033] like Figure 2-5 As shown, the device also includes a sealing and protective device, which is installed on the housing 5 for protection during buffer filling. The sealing and protective device includes several filling tubes 14 fixedly installed on the top of the housing 5. A top plate 15 is fixedly connected to the top of the filling tubes 14. Several filling ports 16 matching the filling tubes 14 are opened on the top plate 15. The size of the filling ports 16 and the filling tubes 14 are matched with the filling needles 10. That is, during the descent of the filling needles 10, they can enter through the filling ports 16, pass through the filling tubes 14, and successfully enter the housing 5 to fill the FOB droppers.

[0034] Furthermore, a first sealing cover plate 23 is provided on the top plate 15. A connecting frame 24 is fixedly installed on one side of the first sealing cover plate 23, and a second sealing cover plate 25 is fixedly connected to one side of the connecting frame 24. The size of the first sealing cover plate 23 and the second sealing cover plate 25 matches the top plate 15, that is, the first sealing cover plate 23 and the second sealing cover plate 25 can completely seal and cover the filling port 16 on the top plate 15. The width of the connecting frame 24 matches the width of the two rows of filling needles 10, and the connecting frame 24 can just expose the two rows of filling ports 16 for the filling needles 10 to fill.

[0035] Furthermore, a support frame 17 is fixedly installed on one side of the housing 5. Reinforcing rods 18, fixedly connected to the housing 5, are installed on both sides of the support frame 17. A threaded rod 19 is rotatably installed between the inner walls of the support frame 17. A threaded sleeve 20 is threadedly connected to the threaded rod 19. A support rod 22, fixedly connected to the first sealing cover 23 and the second sealing cover 25, is fixedly installed on the threaded sleeve 20. A drive motor 21 is fixedly installed on one side of the support frame 17. The output shaft of the drive motor 21 is fixedly connected to the threaded rod 19. (Starting...) The drive motor 21 rotates the threaded rod 19, and the threaded sleeve 20 moves back and forth along the direction of the support frame 17, so that the connecting frame 24 first exposes the first two rows of filling ports 16. After filling is completed, the first sealing cover plate 23 drives the connecting frame 24 to move and expose the last two rows of filling ports 16. At this time, the second sealing cover plate 25 can seal and cover the first two rows of filled filling ports 16. The steps are repeated until the filling is completely finished, which realizes the protective sealing of the filling operation, avoids contamination by pollutants in the air, and improves the filling quality.

[0036] The working principle of this embodiment is as follows: When the tray fixture 6 is placed inside the box 5, the sliding of the slider 12 within the electric slide rail 11 causes the support plate 4 to move the box 5 towards the rear filling needle 10, so that the filling ports 16 of the first two rows are moved directly below the filling needle 10. After alignment, the drive motor 21 is started, causing the threaded rod 19 to rotate. The threaded sleeve 20 drives the support rod 22 to move backward along the support frame 17, causing the first sealing cover plate 23 to move the connecting frame 24 backward, exposing the filling ports 16 of the first two rows. At this time, the cylinder 8 is used... The extension of the piston rod and the start of the peristaltic pump cause the filling needle 10 to descend and move into the filling port 16, passing through the filling tube 14 and into the housing 5, completing the filling of the FOB dropper. After filling, the threaded sleeve 20 drives the first sealing cover 23 and the second sealing cover 25 to move again, allowing the filling ports 16 of the last two rows to leak out. At this time, the second sealing cover 25 seals the filling ports 16 of the first two rows after filling. This step is repeated until all filling is completed, thus protecting the FOB dropper during the filling process, preventing airborne contaminants from contaminating the buffer solution, and improving the filling quality.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
