[0026] Example

[0027] like Figure 1-3As shown, an oral mucosa scraping device includes a tube body 1 and a tube cover 4. The tube cover 4 is arranged at the bottom of the tube body 1 and is threadedly connected to the tube body 1. A partition 10 is arranged in the tube body 1. The partition 10 divides the inside of the tube body 1 into an upper telescopic chamber 2 and a lower storage chamber 3. A through hole is opened on the partition 10. A telescopic component is arranged in the telescopic chamber 2. The telescopic component includes a moving block 5, a push plate 7 and a push rod 9. The moving block 5 is slidably arranged in the telescopic chamber 2. Two vertical strip holes 8 are symmetrically opened on the side wall of the telescopic chamber 2. The push plate 7 passes through the strip holes 8 and is fixedly arranged on both sides of the moving block 5. A push rod 9 is fixedly arranged at the bottom of the moving block 5. The lower end of the push rod 9 passes through the through hole opened on the partition 10 and is located in the storage chamber 3. A sealing ring 11 is provided at the connection between the push rod 9 and the through hole. A horizontal rotating shaft 14 is fixedly arranged at the bottom of the push rod 9, and a scraper 13 is rotatably arranged on the rotating shaft 14.

[0028] It is worth noting that the tube body 1 and the tube cover 4 are provided to protect the scraper 13 used for collection, the telescopic assembly in the telescopic chamber 2 can control the telescopic movement of the scraper 13, the scraper 13 is sealed and stored through the provided storage chamber 3, and the oral mucosa is scraped and collected through the provided scraper 13. Specifically, the push plate 7 can move up and down in the strip hole 8, and the movement of the push plate 7 drives the moving block 5 to move in the telescopic chamber 2, thereby controlling the telescopic movement of the push rod 9, thereby controlling the extension and retraction of the scraper 13, and the scraper 13 can rotate so that the scraper 13 can fit the patient's mouth more closely during scraping, thereby obtaining more oral mucosal samples under the premise of less scraping times, and the sealing ring 11 at the connection between the push rod 9 and the partition 10 mainly plays a sealing effect, so that the scraper 13 after scraping can be stored in the storage chamber without being contaminated by the outside world.

[0029] In some feasible embodiments, a slide groove 6 is symmetrically provided on the side wall of the moving block 5, and a vertical protrusion 12 is correspondingly provided in the telescopic cavity 2. The slide groove 6 matches the protrusion 12 to limit the moving block 5, so that the moving block 5 drives the push rod 9 to move up and down in the telescopic cavity 2 without rotation or displacement.

[0030] In some feasible embodiments, rotating plates 16 are fixedly connected to both ends of the top of the scraper 13 , and the upper portion of the rotating plate 16 is sleeved on the rotating shaft 14 to achieve a rotatable connection between the scraper 13 and the rotating shaft 14 .

[0031] In some feasible embodiments, limit blocks 15 are provided at both ends of the rotating shaft 14 , and the limit blocks 15 are located outside the rotating plate 16 to prevent the scraper 13 from being separated from the rotating shaft 14 .

[0032] In some feasible embodiments, a double helical torsion spring 17 is sleeved on the rotating shaft 14, the middle end of the double helical torsion spring 17 is fixed on the push rod 9, and the left and right ends of the double helical torsion spring 17 are fixedly connected to the top of the scraper 13. When scraping the oral mucosa, the collector applies force to the scraper 13 to tilt the scraper 13 to fit the oral cavity. At this time, the double helical spring 17 generates a rotational force, which tends to pull the scraper 13 back to its original position. Under the interaction of the two forces, the scraper 13 can fit the oral cavity more closely, and the scraper 13 will not rotate at will after the scraping is completed.

[0033] In some feasible embodiments, the scraper 13 is an arc-shaped structure, which can better fit the patient's mouth and reduce discomfort.

[0034] In some feasible embodiments, a plurality of raised structures are provided around the bottom of the scraper 13, and a sponge is provided in the middle of the bottom of the scraper 13. The raised structures can increase the amount of oral mucosa scraped, and the sponge in the middle can absorb the oral mucosa well.

[0035] When in use, first unscrew the tube cover 4, push the push plate 7 to make the push rod 9 drive the scraper 13 to extend out of the tube body 1, then hold the tube body 1 to collect the oral mucosa, after the scraper 13 scrapes the oral mucosa, pull the push plate 7 back to drive the scraper 13 back into the tube body 1, and then screw on the tube cover 4, and the oral mucosa sample is stored in the storage cavity 3. When it is necessary to extract the oral mucosa sample for testing, just unscrew the tube cover 4 and push out the scraper 13 to extract and test.

[0036] In addition, it should be understood that although this specification is described in accordance with the implementation methods, not every implementation method contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art. So far, each embodiment of the present disclosure has been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here. The scope of the present disclosure is defined by the attached claims.
