[0002] Gynecological disease examination and screening are very important. Under the advocacy of the World Health Organization, countries around the world have started screening for gynecological diseases. China has also started screening for "two cancers" to reduce the incidence of gynecological diseases. At present, when conducting gynecological disease examinations, a vaginal dilator is needed to open the vagina before conducting a vaginal examination. When using the existing vaginal dilator, the medical staff needs to first insert the dilator plate into the patient's vagina, and then control the movement of the dilator plate so that the dilator plate stretches the patient's vagina. In this process, when the dilator plate squeezes the patient's vaginal wall too much, the patient will feel uncomfortable, and the patient needs to give timely feedback to the medical staff, who will adjust the squeezing force of the dilator plate on the inner wall of the vagina in time to reduce the patient's discomfort. During the use of the dilator, the patient is prone to greater tension, which causes vaginal contraction, which is not conducive to the use and examination of the dilator.

[0003] To this end, the present invention provides a gynecological vaginal dilator. Summary of the invention

During the use of the dilator, the patient is prone to greater tension, which causes vaginal contraction, which is not conducive to the use and inspection of the dilator. To solve the above problems, the embodiment of the present invention is provided with multiple structures such as the cylinder 2 and the piston plate 21. The specific use process is as follows; During use, the medical staff inserts a pair of expansion plates 1 into the patient's vagina, and then places the first inflation ball 24 in the patient's hand. The patient repeatedly squeezes the first inflation ball 24, and the first inflation ball 24 inflates the cylinder 2 through the first inflation tube 23. The piston plate 21 inside the cylinder 2 is moved toward the end of the cylinder 2 by the squeezing force, and the piston plate 21 drives the expansion plate 1 to move through the linkage frame 22. The pair of expansion plates 1 are driven away from each other, squeezing the inner wall of the vagina, and then stretching the patient's vagina. During the whole process, the patient can control the squeezing force of the expansion plate 1 on the inner wall of the vagina through the first inflation ball 24, which greatly reduces the patient's nervousness. At the same time, when the patient is uncomfortable, the squeezing force of the expansion plate 1 on the inner wall of the vagina can be quickly self-adjusted, which is conducive to the examination.

One end of the movable frame 31 is located outside the plug-in tube 3 and is fixedly connected to the bottom end of the cylinder 2. When a pair of expansion plates 1 move away from each other, the expansion plate 1 drives the movable frame 31 to move relative to the plug-in tube 3 to ensure that no interference occurs when the expansion plate 1 moves relative to the cylinder 2.

[0023] A groove 12 is provided on the opposite sides of a pair of expansion plates 1, and an airbag 13 is arranged inside the groove 12. A second inflation tube 14 is connected to the side of the airbag 13, and the second inflation tube 14 passes through the groove 12 to the end of the expansion plate 1, and the end of the second inflation tube 14 away from the airbag 13 is connected to a second inflation ball 15; when it is necessary to rotate the expander inserted into the vagina, the medical staff inflates the airbag 13 in the groove 12 through the second inflation ball 15 and the second inflation tube 14, and the airbag 13 expands and fully presses against the inner wall of the vagina, which can reduce the contact area between the expansion plate 1 and the inner wall of the vagina, so that the airbag 13 buffers the force between the expansion plate 1 and the inner wall of the vagina when the expansion plate 1 rotates, thereby reducing the patient's discomfort.

[0024] When the airbag 13 is inflated, the air inside the cylinder 2 is released through the deflation structure; when the expansion plate 1 rotates, the expansion plate 1 is controlled to reduce the squeeze on the inner wall of the vagina, and then the airbag 13 is inflated, which can further reduce the discomfort caused to the patient by the rotating expansion plate 1.

[0025] A plurality of limit springs are arranged inside the airbag 13; when the airbag 13 is inflated, the limit springs limit the expansion of the airbag 13 in the horizontal direction, so that the airbag 13 fully expands in the longitudinal direction and then fully contacts the inner wall of the vagina, thereby limiting the squeezing force of the expansion of the airbag 13 on the inner wall of the vagina and ensuring the use effect of the airbag 13; it should be pointed out that the airbag 13 in the horizontal direction is Figure 1 The position of the airbag 13 in is standard.

[0026] A through hole 4 is provided at the hand-held end of the expansion plate 1, and a water pipe 41 is inserted into the through hole 4. The water pipe 41 is located at the hand-held end of the expansion plate 1 and is externally connected to a water pump. During use, when it is necessary to inject a cleaning agent into the vagina, the cleaning agent is extracted by the water pump and then injected into the vagina through the water pipe 41. The cleaning agent does not need to be injected into the vagina through a pair of expansion plates 1, so as to avoid interfering with the examination process of medical staff.

[0027] The through hole 4 is located at one end of the expansion plate 1 for inserting into the vagina and is provided with a blocking plate 42; the top of the blocking plate 42 is rotatably connected to the inner top wall of the through hole 4; the two sides and the bottom of the blocking plate 42 are slidably connected to the inner wall of the through hole 4; A connecting plate 43 is provided at one end of the sealing plate 42 facing the through hole 4, and a return spring 44 is provided between the connecting plate 43 and the inner wall of the through hole 4; when there is no need to inject cleaning agent, the sealing plate 42 blocks the through hole 4 through the connecting plate 43 and the return spring 44 to prevent the liquid secretion of the vagina from flowing into the through hole 4 and causing contamination of the through hole 4.

[0028] A layer of flexible plastic is provided on the surface of the blocking plate 42; when the blocking plate 42 contacts the inner wall of the vagina, the flexible plastic can reduce the degree of stimulation of the blocking plate 42 on the inner wall of the vagina.

[0029] A magnetic block 411 is provided at one end of the water pipe 41 close to the sealing plate 42, and a plurality of magnetic strips 45 are provided around the center line of the water pipe 41 at the end of the sealing plate 42 facing the through hole 4, and the magnetic block 411 and the magnetic strip 45 attract each other; when in use, there is a situation where the anti-inflammatory liquid is sprayed to a designated position in the vagina; therefore, the magnetic block 411 and the magnetic strip 45 are provided, and when in use, the sealing plate 42 is pushed and deflected by the end of the water pipe 41, and the water pipe 41 is rotated at the same time, and the distance between the magnetic block 411 inside the water pipe 41 and different magnetic strips 45 is adjusted, and then the direction of the end of the water pipe 41 is controlled by magnetic force, so that the anti-inflammatory liquid sprayed from the water pipe 41 reaches the designated area, which is convenient for medical staff to use; it should be pointed out that the water pipe 41 is made of flexible plastic and the end can be deformed.

[0030] A brake ring 46 is provided at one end of the through hole 4 away from the sealing plate 42, and the water pipe 41 passes through the brake ring 46 and there is friction between the brake ring 46; the friction between the brake ring 46 and the water pipe 41 can brake the water pipe 41 to ensure that the water pipe 41 remains stable after rotation.

[0031] When in use, the medical staff inserts a pair of expansion plates 1 into the patient's vagina, and then places the first inflatable ball 24 in the patient's hand. The patient repeatedly squeezes the first inflatable ball 24, and the first inflatable ball 24 inflates the cylinder 2 through the first inflatable tube 23. The piston plate 21 inside the cylinder 2 is moved toward the end of the cylinder 2 by the squeezing force, and the piston plate 21 drives the expansion plate 1 to move through the linkage frame 22. The pair of expansion plates 1 are driven away from each other, squeezing the inner wall of the vagina, and then the patient's vagina is stretched open. During the whole process, the patient can control the squeezing force of the expansion plate 1 on the inner wall of the vagina through the first inflatable ball 24, which greatly reduces the patient's nervousness. At the same time, when the patient is uncomfortable, The expansion plate 1 can quickly and self-adjust the squeezing force of the expansion plate 1 on the inner wall of the vagina, which is beneficial to the inspection. When a pair of expansion plates 1 move away from each other, the expansion plate 1 drives the movable frame 31 to move relative to the plug-in tube 3, ensuring that there is no interference when the expansion plate 1 moves relative to the cylinder 2. When it is necessary to rotate the expander inserted into the vagina, the medical staff inflates the airbag 13 in the groove 12 through the second inflation ball 15 and the second inflation tube 14. The airbag 13 expands and fully presses against the inner wall of the vagina, which can reduce the contact area between the expansion plate 1 and the inner wall of the vagina, thereby allowing the airbag 13 to buffer the force between the expansion plate 1 and the inner wall of the vagina when the expansion plate 1 rotates, thereby reducing the patient's discomfort.

[0032] When the airbag 13 is inflated, the air inside the cylinder 2 is released through the deflation structure; when the expansion plate 1 rotates, the expansion plate 1 is controlled to reduce the squeezing of the inner wall of the vagina, and then the airbag 13 is inflated, which can further reduce the discomfort caused by the rotating expansion plate 1 to the patient; when the airbag 13 is inflated, the limit spring limits the expansion of the airbag 13 in the horizontal direction, so that the airbag 13 can fully expand in the longitudinal direction and then fully contact the inner wall of the vagina, thereby limiting the squeezing force of the expansion of the airbag 13 on the inner wall of the vagina and ensuring the use effect of the airbag 13; it should be pointed out that the horizontal direction is Figure 1The position of the airbag 13 in the figure is standard; when in use, when it is necessary to inject a cleaning agent into the vagina, the cleaning agent is extracted by a water pump, and then the cleaning agent is injected into the vagina through the water pipe 41. The cleaning agent does not need to be injected into the vagina through a pair of expansion plates 1 to avoid interfering with the inspection process of medical staff; when it is not necessary to inject the cleaning agent, the blocking plate 42 blocks the through hole 4 through the connecting plate 43 and the return spring 44 to prevent the liquid secretion of the vagina from flowing into the through hole 4 and causing contamination of the through hole 4; when in use, there is a designated amount of liquid in the vagina Therefore, a magnetic block 411 and a magnetic strip 45 are provided. When in use, the sealing plate 42 is pushed and deflected by the end of the water pipe 41, and the water pipe 41 is rotated at the same time to adjust the distance between the magnetic block 411 inside the water pipe 41 and different magnetic strips 45, and then the direction of the end of the water pipe 41 is controlled by magnetic force, so that the anti-inflammatory liquid sprayed from the water pipe 41 reaches the designated area; it is convenient for medical staff to use; the friction between the brake ring 46 and the water pipe 41 can brake the water pipe 41 to ensure that the water pipe 41 remains stable after rotation.
