Description

Technical Field

[0001] The utility model relates to the technical field of medical sampling tools, in particular to a cervical collector. Background Art

[0002] The collector is a device for sampling epithelial cells on the inner wall of the cervix. When using the cervical collector, hold the handle and insert the connecting tube into the inside of the cervix. Then manually control the sliding rod to slide out of the connecting tube, and then extend the sampling head out of the connecting tube, so that the brush set on the surface of the sampling head scrapes off the epithelial cells on the inner wall of the cervix. Then manually control the sliding rod to slide into the inside of the connecting tube, so that the sampling head is stored in the inner wall of the connecting tube. This prevents the brush on the surface of the sampling head from scratching the inner wall of the cervix when sliding out of the connecting tube, and then the cervical epithelial cells can be obtained from the brush on the sampling head, which is convenient for subsequent testing.

[0003] The inventors have found in their daily work that the collector still has at least the following problems: when using the collector to collect cervical endometrial samples, the sampling head will be manually squeezed onto the inner wall of the connecting tube after collection, which makes it easier for the sampling head to be removed. However, in actual use, the sample scraped off from the brush on the surface of the sampling head may stick to the inner wall of the connecting tube, and because the interior of the connecting tube is relatively small, it is difficult to remove the sample from the inner wall of the connecting tube.
