[0018] See attached Figure 1-2The utility model proposes an oral cell collection device, comprising a test tube body 1, a fixed plug 6, a sampling component and a top sealing component; wherein the test tube body 1 is a cylindrical structure, and its upper end is an open port for accommodating and preserving the collected cell sample preservative solution. A label attachment area can be set on the outside of the test tube body 1 for marking the sample preservative solution information, such as the sampling date, sampler information, etc., to facilitate subsequent management and tracking.

[0019] The fixed plug 6 is coaxially embedded in the inner wall near the upper open end of the test tube body 1; the top sealing component is arranged at the upper open end of the test tube body 1; the sampling component is coaxially inserted into the test tube body 1 and the top sealing component after sampling, and it coaxially passes through the top sealing component and the fixed plug 6 from top to bottom in sequence.

[0020] In this embodiment, the sampling assembly includes a breakable rod 4, an adjusting rod 401 and a sampling head 3; after sampling, the breakable rod 4 coaxially passes through the test tube plug fixing member 7 and the fixed plug 6 from top to bottom in sequence; the upper end of the adjusting rod 401 is coaxially engaged with the lower end of the breakable rod 4, and its outer diameter is smaller than the outer diameter of the breakable rod 4; the upper end of the sampling head 3 is engaged with the lower end of the adjusting rod 401; the breakable rod 4 is provided with an easy-to-break structure, such as a dotted line structure, at the junction of the inside and outside of the top sealing assembly; and the outer diameter of the breakable rod 4 matches the inner diameter of the fixed plug 6, so that the breakable rod 4 can both pass through the fixed plug 6 and be fixed and limited by the fixed plug 6, ensuring that the breakable rod 4, the adjusting rod 401 and the sampling head 3 do not contact the inner wall of the test tube body 1 during the collection process, thereby avoiding potential contamination of the sample preservation liquid.
