[0032] For example, see Figures 1 to 5

[0033] The reproductive tract sample self-sampling kit includes a sleeve 5, which is cylindrical with openings at both ends. The top and bottom outer walls of the sleeve 5 are both provided with threaded grooves. The top of the sleeve 5 is threadedly connected to a cover 3, and the cover 3 is connected to a connecting rod 6 through a lifting device. A swab 8 is fixedly connected to one end of the connecting rod 6. The bottom end of the sleeve 5 is provided with a preservation head 10, the top of the preservation head 10 is open, and the bottom is hemispherical, conical or cylindrical. A film 11 is connected between the sleeve 5 and the preservation head 10 through a clamping device. A sample preservation device is provided in the preservation head 10, and the sample preservation device includes a cell preservation solution 9. The cell preservation solution 9 is located inside the preservation head 10, and the cell preservation solution 9 is a physiological saline cell preservation solution.

[0034] A stopper 7 is fixedly connected to the side wall of the connecting rod 6. When the user inserts the swab 8 into the reproductive tract for sampling, when the user feels the stopper 7, he / she knows that the swab 8 is fully inserted.

[0035] See also Figure 1 and Figure 2 The lifting device includes a threaded column 2, which is threadedly connected to the middle side wall of the cover 3. The threaded column 2 passes through the side wall of the cover 3. One end of the connecting rod 6 is fixedly connected to the side wall of one end of the threaded column 2. The other end of the threaded column 2 is fixedly connected to a handle 1, which is arranged in a semicircular shape. When the connecting rod 6 needs to be lifted or lowered in the sleeve 5, the handle 1 can be first grasped to drive the threaded column 2 to rotate and twist on the cover 3. The threaded column 2 can be lifted or lowered along the spiral of the cover 3 to drive the connecting rod 6 to be lifted or lowered in the sleeve 5.

[0036] Specifically, the clamping device includes a clamping ring groove 4, which is provided on the inner side wall of the top opening of the preservation head 10, and an internal thread is provided on the inner ring side wall of the clamping ring groove 4. The preservation head 10 is threadedly connected to the bottom end of the sleeve 5 through the internal thread on the clamping ring groove 4, and the film 11 is located between the bottom end of the sleeve 5 and the clamping ring groove 4. When the film 11 needs to be clamped and fixed between the preservation head 10 and the sleeve 5, the circular film 11 can be placed in the clamping ring groove 4 first, and then the clamping ring groove 4 is threadedly tightened on the outer side wall of the bottom end of the sleeve 5, so that the film 11 can be fixedly clamped in the sleeve 5 and the preservation head 10.

[0037] The working principle of the present invention is:

[0038] When in use, the user can first screw the cover 3 to remove the cover 3 from the sleeve 5, and then grasp the cover 3 to drive the swab 8 into the reproductive tract to take a sample. After the sampling is completed, the swab 8 is reinserted into the sleeve 5, and the cover 3 is tightened on the upper end of the sleeve 5 again, and then the handle 1 is grasped to drive the threaded column 2 to rotate and twist on the cover 3. The threaded column 2 rotates and twists along the cover 3 to drive the swab 8 at the bottom end of the connecting rod 6 to descend. When the swab 8 descends, it can penetrate the film 11 and enter the preservation head 10. The cell preservation fluid 9 in the preservation head 10 will soak the sampled swab 8, which can preserve the collected cells and the sample will not be lysed. In this way, the swab 8 can be kept in a good state before being transported to the detection experiment and can be kept for a long time.

[0039] For example 2, please refer to Figures 6-7

[0040] The difference between the second embodiment and the first embodiment is that the sample preservation device includes a breathable mesh layer 12, which is fixedly connected to the inner wall of the preservation head 10. A filling cavity is provided between the breathable mesh layer 12 and the inner wall of the preservation head 10. A desiccant 13 is provided in the filling cavity. The desiccant 13 is calcium chloride. When the swab 8 descends and penetrates the film 11 to enter the preservation head 10, the desiccant 13 in the preservation head 10 keeps the sample collected on the swab 8 dry, and the sample will not be lysed. Such a sample can be transported without waiting for drying and can be stably preserved.

[0041] It should be noted that when the film 11 is a diaphragm with air holes, there is no need to rotate the pressing handle, and the desiccant can directly and continuously keep the sample collected on the swab 8 dry.

[0042] For example 3, please refer to Figure 8

[0043] The difference between Example 3 and Example 1 is that the preservation head 10 is connected to the inner thread of the bottom end of the sleeve 5 through the external thread of the outer wall, and the film 11 is fixedly connected to the top of the preservation head 10 to seal the cell preservation solution 9. The overall structure is simpler and convenient for production and promotion.

[0044] Example 4, please refer to Fig. 9

[0045] The fourth embodiment is different from the first embodiment in that the connecting rod 6 is hollow, one end of the connecting rod 6 is fixedly connected to the swab 8, the other end of the connecting rod 6 is fixedly connected to the liquid storage chamber 14, one end of the liquid storage chamber 14 is threadedly connected to the threaded column 2, the bottom of the threaded column 2 may have a pointed head, the other end of the liquid storage chamber 14 is provided with a film 11, the liquid storage chamber 14 is filled with a cell preservation solution 9, the liquid storage chamber 14 is connected to the connecting rod 6, the threaded column 2 can be twisted, the pointed head can be driven downward to pierce the film 11, so that the cell preservation solution 9 passes through the film 11 from the hollow connecting rod 6 to the swab 8, soaking the swab head, and preserving the sample. The whole is covered with an outer tube 15 outside, which can maintain a sterile environment and prevent the swab head from being contaminated after sampling.

[0046] Embodiment 5

[0047] The difference between the fifth embodiment and the third embodiment is that the preservation head 10 is connected to a plugging cap (not shown) with two ends that can be threadedly connected through the threaded connection of the outer wall, and the other end of the plugging cap is connected to the threaded opening of the tube. After sampling, the swab 8 is directly broken into the preservation head 10 with the preservation solution, and the plugging cap is tightened and directly sent back to the preservation head, and the overall structure is simpler. Alternatively, after sampling, the preservation head is directly connected to the tube by a screw, and the handle is rotated to immerse the swab head downward into the preservation solution, and then it is sent back, and the plugging cap can be discarded.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
