DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-4This invention provides a technical solution: a reproductive secretion sampling device, including a gripping cylinder 1. A bidirectional lead screw 3 is threaded at the center of the inner cavity of the gripping cylinder 1. Two sets of vaginal specula 4 are symmetrically mounted on the surface of the bidirectional lead screw 3. Each set of two sets of vaginal specula 4 has a first moving groove 6 at its center. Two sets of two sets of vaginal specula 4 have symmetrically mounted second moving grooves 7 on both sides of their outer surfaces. Moving blocks 8 are slidably mounted on the surface of the second moving grooves 7. A positioning mechanism is provided inside each moving block 8. A filling tube 13 is slidably mounted on one side of each set of two moving blocks 8. A baffle 14 is fixedly mounted at one end of each filling tube 13. An air pump 15 is mounted on the outer surface of the baffle 14. Four sets of mounting rings 16 are fixedly mounted at the other ends of the two sets of filling tubes 13, with each two sets of rings positioned in pairs. Airbags 17 are fixedly installed between each set of mounting rings 16, and several connecting rods 18 are fixedly installed in a ring at equal intervals between two adjacent sets of airbags 17 in the middle. The filling tube 13 slides in the first moving groove 6. The vaginal speculum 4 opens the vaginal opening and then drives the moving block 8 to slide along the second moving groove 7 towards the vaginal opening of the first moving groove 6. The moving block 8 drives the two sets of airbags 17 to penetrate into the vagina through the filling tube 13, mounting rings 16 and connecting rods 18. At the same time, the filling tube 13 slides synchronously along the first moving groove 6. With the start of the air pump 15, the two sets of airbags 17 are inflated to block the reproductive tract and prevent the backflow of secretions. The secretions are collected into the sampling hole in the middle of the airbag using a sterile cotton swab and a protective cap to avoid sample exposure.

[0024] like Figures 1-4 As shown, several anti-slip strips 2 are fixedly installed on the outer surface of the gripping cylinder 1, and guide rods 5 are symmetrically fixed on both sides of the inner wall of the gripping cylinder 1. The guide rods 5 are slidably connected to the vaginal speculum 4. The anti-slip strips 2 on the outer surface of the gripping cylinder 1 significantly enhance the frictional resistance during operation and effectively prevent operational errors caused by hand slippage during use. The guide rods 5 symmetrically distributed on the inner wall form a precise sliding fit mechanism with the vaginal speculum 4, which not only ensures the accuracy of the stable axial movement of the vaginal speculum 4, but also avoids the risk of displacement caused by unilateral force through the double guide structure.

[0025] like Figures 1-4 As shown, the positioning mechanism includes a receiving cavity 9 on one side of the lower surface of the moving block 8. Several return springs 12 are fixedly installed on the inner wall of the receiving cavity 9. A limiting plate 11 is fixedly installed at one end of the several return springs 12 and is slidably connected to the receiving cavity 9. A push-pull rod 10 is fixedly installed at the center of the outer surface of the limiting plate 11 and is slidably connected to the moving block 8. When the push-pull rod 10 is pulled outward, the push-pull rod 10 drives the limiting plate 11 to slide along the receiving cavity 9 and compress the return springs 12. When the moving block 8 slides along the second moving groove 7 to the designated area, the push-pull rod 10 is released. As the return spring 12 rebounds and resets, the limiting plate 11 abuts against the surface of the vaginal speculum 4 to limit the movement, thereby ensuring stable sampling of reproductive secretions.

[0026] As Figures 1-4 shown, the dilator 4 is made of silicone, the mounting ring 16 and the connecting rod 18 are made of polyamide, the connecting rod 18 is internally provided with a connecting pipe, the dilator 4 is made of medical silicone, which has excellent biocompatibility and soft elasticity, significantly reducing the irritation to the patient's mucosa and improving the use comfort; the mounting ring 16 and the connecting rod 18 are made of polyamide 8, which has high strength and fatigue resistance, ensuring the stability and long-term durability of the mechanical structure; the design of the connecting rod 18 internally provided with a connecting pipe integrates the internal pipeline, which not only simplifies the external structure and enhances the compactness of the equipment, but also effectively protects the transmission channel 8, taking into account the function expansion and safety.

[0027] Working principle: in use, first place the two sets of dilators 4 on both sides of the vaginal orifice, then twist the bidirectional screw rod 3, the bidirectional screw rod 3 drives the two sets of dilators 4 to move towards each other along the guide rod 5, thereby expanding the vaginal orifice, at this time the filling pipe 13 slides up and down along the inside of the moving block 8, and is blocked and limited under the action of the baffle 14, then pull the push-pull rod 10 outward, the push-pull rod 10 drives the limiting plate 11 to slide along the containing cavity 9 and compresses the return spring 12, the moving block 8 slides along the second moving groove 7 to the first moving groove 6 of the vaginal orifice, while the moving block 8 drives the two sets of air bags 17 to penetrate into the vagina through the filling pipe 13, the mounting ring 16 and the connecting rod 18, at the same time the filling pipe 13 will slide synchronously along the first moving groove 6, when the moving block 8 slides along the second moving groove 7 to the specified area, release the push-pull rod 10, and the limiting plate 11 is limited by the surface of the dilator 4 with the return of the return spring 12, start the air pump 15 to inflate the two sets of air bags 17, block the genital tract, prevent backflow of secretions, and use a sterile cotton swab and protective cap to collect secretions through the pre-set sampling hole in the middle of the air bag, ensuring stable sampling of reproductive secretions and reducing the risk of pollution, the whole operation is convenient and easy to use, and is suitable for large-scale application and promotion.

[0028] The above is only a preferred embodiment of the present application, and does not limit the form of the present application, any skilled person in the art can use the disclosed technical content to make changes or modifications to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belongs to the protection scope of the technical solution of the present application.
