Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of cell collector technology, and more specifically to a self-disinfecting cell collector. Background Technology

[0002] For patients suspected of having malignant tumors, clinical practice often involves performing biopsies on lesions or unusual sites using a needle puncture or fiberoptic bronchoscope to confirm the diagnosis. For example, if nodules or masses are found in the lungs, the extracted specimens are sent to the pathology department for further diagnosis. However, some patients initially present with pleural effusion or ascites as the main symptoms, with no clear lesions seen on imaging, or lesions present but in unusual locations that make biopsy impossible or too risky, such as lesions near the heart or major blood vessels. In these patients, the pleural effusion or ascites is highly likely caused by malignant tumors. Therefore, in such patients, sending pleural or ascites fluid for examination can help identify cancer cells and aid in diagnosis.

[0003] Current techniques for extracting pleural and peritoneal fluid involve puncturing the chest and abdomen, draining the fluid using pleural and peritoneal drainage tubes, and collecting 50-100 ml of the fluid in a bottle before sending it to the laboratory for testing. However, because the amount of fluid collected is too small, the number of cancer cells is low, resulting in a very low detection rate and poor testing results. This affects the doctor's ability to make an accurate diagnosis and hinders the next steps in the treatment plan.

[0004] To improve cell collection efficiency, a search revealed a utility model patent with publication number CN220317799U, which discloses a pleural and peritoneal fluid cell collector belonging to the field of medical device technology. The collector includes a collection assembly comprising a base plate, a collection bucket, two support rods, a placement plate, a collection bottle, two baffles, a cell sieve, a valve, and a conduit. In use, the valve is opened to allow a large amount of extracted pleural and peritoneal fluid to flow into the collection bottle. The fluid then flows through the bottle and back into the collection bucket. A cell sieve inside the collection bottle traps cells. When filtration is nearly complete, the valve is closed, leaving a portion of the fluid in the bottle. This concentrated fluid contains a higher concentration of cells, facilitating cancer cell detection and improving the detection rate of cancer cells in pleural and peritoneal fluid.

[0005] However, the aforementioned existing technology involves an open collection container, which exposes the pleural and peritoneal fluid to the external environment during cell collection. Dust and bacteria in the external environment can easily affect the detection results of cells in the pleural and peritoneal fluid. Utility Model Content

[0053] Reference Figures 2-5 The positioning mechanism includes a first cavity, an annular groove 11, a positioning disk 12, a positioning post 14, a synchronous rotation mechanism, and a position adjustment mechanism. The first cavity is located within the sealing disk 7, and multiple positioning openings are provided on the side wall of the first cavity. The annular groove 11 is located on the side wall of the mounting groove. The positioning disk 12 is slidably disposed within the first cavity, and multiple positioning grooves 13 are provided on the side wall of the positioning disk 12, each corresponding to a positioning opening. The positioning post 14 is rotatably disposed within the positioning groove 13, and a positioning block 15 is fixedly disposed on the side wall of the positioning post 14. The synchronous rotation mechanism is... A positioning disk 12 is placed on the positioning disk 12 to drive multiple positioning pins 14 to rotate synchronously. A position adjustment mechanism is set on the sealing disk 7 to drive the positioning disk 12 to move within the first cavity. The synchronous rotation mechanism includes a second cavity, a first gear ring 17, and a drive mechanism. The second cavity is opened within the positioning disk 12, and multiple first gears 16 are rotatably arranged within the second cavity. The first gears 16 are fixedly connected to the positioning pins 14. The first gear ring 17 is rotatably arranged within the second cavity, and the first gear ring 17 meshes with the first gears 16. The drive mechanism is set on the positioning disk. On 12, a drive mechanism is used to drive the first gear ring 17 to rotate. The drive mechanism includes a second gear 18, a drive prism 19, and a first handwheel 20. The second gear 18 is rotatably disposed in the second cavity and meshes with the first gear ring 17. The drive prism 19 is rotatably disposed in the first cavity and passes through the second gear 18 and the positioning disk 12. The drive prism 19 is rotatably connected to the positioning disk 12. The first handwheel 20 is rotatably disposed on the sealing disk 7 and is fixedly connected to the drive prism 19. The second gear 18 has an opening... The first drive port and the positioning plate 12 have a second drive port. The drive prism 19 passes through the first drive port and the second drive port. The drive prism 19 is slidably connected to the side wall of the first drive port. A torsion spring is fitted on the drive prism 19. The two ends of the torsion spring are fixedly connected to the side wall of the first cavity and the drive prism 19, respectively. The positioning block 15 moves around the positioning post 14 by rotating the first handwheel 20, so that one end of the positioning block 15 extends into the annular groove 11. The sealing plate 7 can be installed and fixed by the cooperation between the positioning block 15 and the annular groove 11.

[0054] Reference Figure 5 The position adjustment mechanism includes a threaded rod 21 and a second handwheel 22. The threaded rod 21 is rotatably disposed in the first cavity and passes through the positioning plate 12 through a threaded engagement. The second handwheel 22 is rotatably disposed on the sealing plate 7 and is fixedly connected to the threaded rod 21. A sealing ring is fixedly disposed at the bottom of the mounting groove. The rotation of the second handwheel 22 can drive the positioning block 15 to move, thereby fixing the sealing plate 7 by the compression of the annular groove 11 by the positioning block 15 against the side wall of the mounting groove, thus improving the sealing performance during the collection of pleural and peritoneal fluid cells.

[0055] In this embodiment, during use, the operator places the screening ring 5 into the filter housing 1. Then, the operator rotates the first handwheel 20. The rotation of the first handwheel 20 drives the drive prism 19 to rotate. Simultaneously, the sliding engagement between the drive prism 19 and the first drive port drives the second gear 18 to rotate. The meshing of the second gear 18 with the first gear ring 17 drives the first gear ring 17 to rotate. Furthermore, the meshing of the first gear ring 17 with the first gear 16 drives the first gear 16 and the positioning pin 14 to rotate, allowing the positioning block 15 to move around the positioning pin 14 and retract into the positioning groove 13. The operator then inserts the sealing disc 7 into the mounting groove. Afterward, the operator releases the first handwheel 20, which, under the action of the torsion spring, resets the first handwheel 20, causing the positioning block 15 to move around the positioning pin 14 and extend into the annular groove 11. At this point, the operator rotates the second handwheel 22, which drives the threaded rod 2... 1. Rotation is performed, which in turn drives the positioning plate 12 and positioning block 15 to move through the threaded engagement of the threaded rod 21 with the positioning plate 12. This allows the positioning block 15 to squeeze the side wall of the annular groove 11, thereby fixing the sealing plate 7 in the installation groove and improving the sealing effect between the sealing plate 7 and the installation groove. Then, the operator controls the ultraviolet lamp 23 to work and irradiates the filter plate 6 and the filter housing 1 for more than two hours. After that, the operator opens the pipeline control valve 3 and introduces pleural and peritoneal fluid into the filter housing 1 through the inlet pipe. The pleural and peritoneal fluid can then be filtered through the filter plate 6, thus trapping cells in the filter housing 1. When filtration is almost complete, the pipeline control valve 3 is closed in time, leaving a portion of the pleural and peritoneal fluid in the filter housing 1. The filter housing 1 contains concentrated pleural and peritoneal fluid with a large number of cells. Then, the operator places the culture dish under the outlet pipe 2 and opens the pipeline control valve 3 to collect the concentrated pleural and peritoneal fluid, which facilitates the detection of cancer cells and can improve the detection rate of cancer cells in pleural and peritoneal fluid.
