With reference to fig. 1, a vaginal secretion sampling device for gynecological clinical use may include a sampling assembly 10 for sampling the vaginal secretion; and a second tube 20 for wrapping the sampling assembly 10 and extending into the vagina. The sampling assembly 10 can be extended from the second tube 20 to the inner wall of the vagina for sampling. A valve assembly 30 is provided on the inner wall of the second tube 20, the valve assembly 30 being connected to the inner wall of the second tube 20 by means of a flexible connection such that the valve assembly 30 can be moved between the open and closed positions.

According to a preferred embodiment, the inner diameter of the second tubular 20 is adapted to allow the sampling assembly 10 to pass out of the second tubular 20 in a collinear manner with the axis of the second tubular 20, such that the sampling assembly 10 can contact and sample secretions after passing through the second tubular 20. As shown in fig. 2, the valve assembly 30 is disposed on the inner wall of the second tube 20. Valve assembly 30 is used to control the withdrawal of sampling assembly 10 from second tubular 20, to isolate sampling assembly 10 from the environment, and to provide a passageway for sampling assembly 10 to pass therethrough as sampling assembly 10 is withdrawn from second tubular 20.

According to a preferred embodiment, the valve assembly 30 is composed of several valve units 31. The valve unit 31 is disposed on the inner wall of the second tube 20 by means of a flexible connection. The valve unit 31 can be spliced to form a curved surface matching the inner diameter of the second tube 20 in the closed state. So that the second circular tube 20 can separate the inside of the second circular tube 20 from the external environment under the plugging of the cambered surface. In order to ensure that the valve assembly 30 can be opened when pushed by the sampling assembly 10, the top end of the arc is set to point to the end of the second tube extending into the vagina. When the valve assembly 30 is not stressed, the valve unit 31 is in a closed state, and when the valve unit 31 is under pressure from the end extending into the female channel, when the valve unit 31 is under pressure and has a movement trend corresponding to the pressure direction, because the arc surface points to the end of the second circular tube 20 extending into the female channel in the top end direction, mutual extrusion can be generated between the valve units 31, so that the connecting seam between the valve units 31 is reduced, and the sealing performance of the arc surface is further ensured.

According to a preferred embodiment, when sampling assembly 10 passes through sampling assembly 20, valve units 31 are each squeezed between the peripheral side of sampling assembly 10 and the inner wall of second tube 20 such that a passage is formed between valve units 31 for passage of sampling assembly 10. And the gap between the peripheral side of the sampling assembly 10 and the inner wall of the second tube 20 can keep better sealing performance due to the arrangement of the valve unit 31, and the secretion in the vagina can be prevented from flowing into the device from the gap. Preferably, the connection between the valve assembly 30 and the second tube 20 can be a flexible connection, a soft connection or a one-piece connection.

According to a preferred embodiment, as shown in fig. 2, when the number of the valve units 31 is 4, the valve units 31 have a quarter arc structure. The bottom edge diameter of the arc surface formed by the valve unit 31 is the same as the inner diameter of the second circular tube 20, and the inner walls of the second circular tube 20 at the bottom edge are overlapped when the valve unit 31 is closed. The valve unit 31 is of a bendable and deformable structure. When the sampling assembly 10 passes through the second round tube 10, the top of the valve unit 31 can be squeezed by the sampling assembly 10 to deform the inner wall of the second round tube, so that the effect of allowing the sampling assembly 10 to pass for sampling when the inside of the second round tube 20 is separated from the outside is achieved.

According to a preferred embodiment, sampling assembly 10 includes a brush head 11, a connecting rod 12, and a base 13. As shown in figure 3, the brush head 11 is a spherical cavity structure and is used for sampling secretion on the inner wall of the vagina in a contact mode. The surface of the brush head 11 is uniformly provided with small holes penetrating to the inner cavity, so that vaginal secretion can enter the brush head 11 from the small holes for storage. The connecting rod 12 is used to connect the brush head 11 to the base 13 so that the brush head 11 can be passed through the valve assembly 30 from within the second tube 20 to the inner wall of the vagina under the force of the base 13 or retracted from within the vagina into the second tube 20 after sampling. The base 13 and the second circular tube 20 are in interference connection through a rubber strip, and the sealing performance of the sampling assembly 10 when the sampling assembly is not used is further ensured by matching with the valve assembly 30. The other end of the base 13 is connected with a push rod 14. The base 13 can make translational sliding in the second round tube 20 in the same line with the axis of the second round tube 20 under the pushing of the push rod 14. The brush head 11 can not contact with the skin and air in the sampling process or after the sampling is finished, so that the secretion sample can not be polluted.

According to a preferred embodiment, the inner wall of the second tube 20 is further provided with a first limiting plate 21 for preventing the sampling assembly 10 from not fully extending into the inner wall of the vagina or extending into the vagina too much to cause discomfort to the patient and a second limiting plate 22 for preventing the sampling assembly 10 from fully sliding out of the second tube. The first limiting plate 21 and the second limiting plate 22 are respectively disposed at two ends of the sampling assembly 10. The first limiting plate 21 and the second limiting plate 22 are arranged in cooperation with the base 13, so that the base 13 can only slide between the first limiting plate 21 and the second limiting plate 22. The first limiting plate 21 is matched with the second round pipe 20 and is arranged perpendicular to the axis of the second round pipe 20. The first limiting plate 21 is provided with a first through hole 211 through which the brush head 11 and the connecting rod 12 pass. The second limiting plate 22 is provided in the same manner as the first limiting plate 21. The second limiting plate 22 is provided with a second through hole 221 at the axle center for the push rod 14 to pass through. The diameter of the second through hole 221 is set in accordance with the diameter of the push rod 14.

According to a preferred embodiment, in order to prevent the vaginal wall from being scratched when the end of the second tube 20 extending into the vagina is inserted, the end of the second tube 20 extending into the vagina is polished to have a smooth rounded shape, thereby protecting the human body.

According to a preferred embodiment, the outer end of the push rod 14 is provided as a disc-like structure that cooperates with the push rod 14 for pushing. So that the push rod 14 can be attached to a finger when being pushed to sample, the slipping phenomenon is avoided, and the push rod 14 can be pulled out by pulling the disc structure when the push rod 14 needs to be pulled out.

According to a preferred embodiment, the circumference of the second round tube 20 is uniformly provided with the scale bars and the numbers matched with the scale bars, so that the extending distance of the second round tube 20 can be known by observing the scale bars.

This device is when using, stretch into the end with second pipe 20 earlier and insert the vagina in, whether stretch into to the sampling position through observing the scale bar second pipe 20, then promote push rod 14, it stretches out from second pipe 20 intraductally to drive base 13 with brush head 11 and connecting rod 12, under the effect of first limiting plate 21, can restrict base 13 at the sampling position, rotatory push rod 14 is to brush head 11 and the abundant contact sample of vaginal wall, it is intraductal to pull push rod 14 with brush head 11 and the withdrawal of push rod 14 second pipe 20 after the sample is accomplished, valve module 30 folds under self deformation, take second pipe 20 out, accomplish the sample.
