Description

[Technical field]

[0001] The present invention relates to the technical field of medical equipment, and in particular to an auxiliary pressure device for stress urinary incontinence. [Background technology]

[0002] Stress urinary incontinence, abbreviated as SUI, is mainly caused by the relaxation of the pelvic floor muscles, which reduces the stress on the urethra, and usually occurs when the patient exerts pressure on the abdomen, such as sneezing, coughing, laughing loudly, or walking quickly, which increases the intra-abdominal pressure and causes inconvenient urine leakage from the urethral orifice. In daily life, SUI is uncomfortable and embarrassing for women, and the pessary, which is the most commonly used treatment for SUI, has become a viable non-surgical option to treat SUI.

[0003] However, conventional pessaries, when left in the vagina for a long period of time, can cause discomfort to the user, and there is a risk of them falling off during use. Due to the above-mentioned circumstances, there is still a high degree of dependency on doctors during use.

[0004] In summary, how to obtain a vaginal indwelling device that combines comfort and convenience to solve the SUI-related problems currently faced by women is an issue that needs to be addressed urgently. Summary of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0042] Hereinafter, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only some embodiments of the present invention and not all embodiments.

[0043] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs. The technical terms used in the present specification are only for describing specific examples and are not intended to limit the present invention. The technical term "and / or" used in the present specification includes any and all combinations of one or more related items.

[0044] The present invention relates to an auxiliary pressure application device for stress urinary incontinence, and includes an expansion body 1 which is a vaginal placement structure having a first state 01 before placement in the vagina and a second state 02 after placement in the vagina, an adjustment system 2 for maintaining and / or releasing the first state 01 of the expansion body 1, and a biasing section 3 which is a traction structure connected to the expansion body 1 and biases the expansion body 1 so that the user removes it from the vagina.

[0045] The present invention provides an auxiliary pressurizing device for stress urinary incontinence having an adjustment system 2, and aims to improve the convenience of inserting the expansion body 1 into the vagina by imparting the first state 01 using the adjustment system 2, improving comfort during the process of inserting the expansion body 1 into the vagina, while improving the positional stability of the expansion body 1 within the vagina, avoiding discomfort due to position changes during use and embarrassment due to unexpected falling off, and minimizing dependency on doctors.

[0046] After the expander 1 is inserted into the vagina, the actuation part 3 is partially disposed outside the human body, and by adopting a flexible material, the impact on the human body can be reduced. A flexible thread is a relatively common choice, and a common embodiment is a cotton-like thread. This material is not the only choice for the material of the actuation part 3 in the present invention, and it is clear that other materials that can be tolerated by the human body and do not cause discomfort to the human body during the friction process are all included in the scope of the present invention.

[0047] In a preferred embodiment, the expansion body 1 has an integral structure. In this embodiment, the expansion body 1 can have better integrity and can ensure structural stability, while the shape can be more easily controlled to a shape that is comfortable for the human body, resulting in an excellent design effect.

[0048] In contrast to the above embodiment, the adjustment system 2 may have the following embodiments for implementing the invention, and those skilled in the art can easily and clearly understand the technical objective of the present invention by listing them one by one. EXAMPLES

[0049] In this embodiment, the adjustment system 2 is used to maintain the first state 01 of the extension body 1, and when moved away from the extension body 1, the extension body 1 naturally assumes the second state 02.

[0050] Specifically, the extension body 1 includes at least two pull-out ends 11 uniformly distributed along the circumferential direction, with the root portions 11a of each pull-out end 11 connected and the tips 11c being free ends, and the adjustment system 2 is used to maintain the extension body 1 in a first state 01, in which the tips 11c are close to or attached to each other, and in which the tips 11c are spaced apart from each other, and the biasing portion 3 is connected to the connection points of each pull-out end 11.

[0051] As shown in FIG. 1, the configuration of the above embodiment is shown. In the above embodiment, in the first state 01, when the tips 11c of the pull-out ends 11 approach or stick together, the coverage area of ​​the tips 11c of each pull-out end 11 is inevitably reduced, and such a reduced state is the main reason for increasing the convenience of entering the vagina. In the second state 02, the tips 11c are separated from each other, and the increased coverage area improves the adhesion force with the vaginal wall 4, and the vaginal wall 4 is pressed and deformed, thereby improving the pressing force against the urethra, and effectively improving the condition of stress urinary incontinence.

[0052] In this embodiment, the expandable body 1 is preferably integrally molded, and the pull-out ends 11 are deformed by the pressure of the adjustment system 2, and after the expandable body 1 and the adjustment system 2 are separated, each pull-out end 11 elastically returns to its original expanded state. In this form, when the material of the expandable body 1 is constant, different pressing forces against the vaginal wall 4 can be obtained after being inserted into the vagina by rationally controlling the size of the expandable body 1 in the second state 02, that is, the expandable body 1 can have different model numbers according to such forms, and users with different needs can select and use them.

[0053] In order to further improve the comfort of use, as a first preferred configuration form of the above embodiment, the pull-out end 11 is an elastically curved structure of a buckle, and the tip 11c of the pull-out end 11 is spaced apart from the vaginal wall 4 in the second state 02.

[0054] As shown in Figures 2 and 3, in this embodiment, the pull-out end 11 includes a base portion 11a, an attachment portion 11b with the vagina, and a tip portion 11c, in this embodiment the tip portion 11c is not attached to the vaginal wall 4, but is attached to the vaginal wall 4 through the intermediate portion between the tip portion 11c and the base portion 11a. This configuration makes it possible to avoid the end portion from pressing against the vagina with an uncomfortable feeling, while the attachment of the complete central portion with the vaginal wall 4 makes the use of the expander body 1 more stable. The curved configuration of the pull-out end 11 makes the attachment range 03 extend relatively on both sides of the attachment portion 11b, providing a larger working range than that with the vaginal wall 4, which is obviously advantageous for stable fixation of the expander body 1.

[0055] In this embodiment, the cross section of the curved structure may be circular, elliptical, etc., or at least the side facing the vaginal wall 4 must be smooth, which ensures comfort when pressed against the vaginal wall 4, while the shape of the other side provides a wider range of options since it does not come into direct contact with the human body.

[0056] In this embodiment, as shown in Fig. 1 and Fig. 2, the lead-out ends 11 may be in the form of a rod, and at the attachment site 11b with the vaginal wall 4, a larger attachment area with the vaginal wall 4 can be obtained by appropriate expansion, improving comfort and positional stability. The above figures show a form in which six lead-out ends 11 are uniformly distributed, and the above number shows only one embodiment here, and other numbers such as 2, 3, 4... are also within the scope of the present invention, and it goes without saying that the selection of the number should ensure the possibility of processing and application.

[0057] As a second configuration form of this embodiment, the pull-out end 11 can be attached to the vaginal wall 4 through different locations, specifically, the pull-out end 11 includes an elastic connecting structure and an attached end connected to one end of the connecting structure as a tip 11c, the other end of the connecting structure is a base portion 11a, the attached end is expanded outward relative to the connecting structure, and the attached end is attached to the vaginal wall 4 in a second state 02.

[0058] In the first configuration form, the curved structure is the configuration form of the pulled-out end 11, and its central part is attached to the vaginal wall 4. In this configuration form, the curved structure is a part of the pulled-out end 11, and is attached to the vaginal wall 4 by the attached end connected to it. In this embodiment, the difference from the above example in which the attachment stability is ensured by the optimized form of the attachment point 11b is that the attachment stability of the entire auxiliary pressure applying device is ensured by optimizing the attached end structure.

[0059] FIG. 4 shows a form in which three pull-out ends 11 including three bent structures and three bonding ends are provided, and FIG. 5 shows a form in which two pull-out ends 11 including two bent structures and two bonding ends are provided. The bonding ends selected in the above figures are all partial spheres, and of course, the sphere referred to here may be a circular sphere, an elliptical sphere, etc., and the spherical surface of the sphere is the part that is bonded to the vaginal wall 4 during use, and by controlling the volume and size of the sphere, the bonding area with the vaginal wall 4 can be effectively adjusted.

[0060] The auxiliary pressure device in the present invention can control the positional stability after insertion into the vagina by controlling the shape and number of the bonding ends. In this embodiment, the more the number of pull-out ends 11, the more bonding ends are used to bond to the inner wall of the vagina, so the dimensions of the bonding ends can be appropriately reduced. Conversely, the fewer the number of pull-out ends 11, the fewer the bonding points 11b with the vagina, so the dimensions of the bonding ends can be appropriately increased, as shown in comparison between Figures 4 and 5. In the above cases, only product costs and the like are taken into consideration, and are not used as a basis for limiting the scope of the present invention.

[0061] During use, different attachment points 11b are formed between the attachment end in this embodiment and the vaginal wall 4, such as attachment point 11b-1 to attachment point 11b-3 shown in FIG. 4 and attachment point 11b-4 to attachment point 11b-5 shown in FIG. 5. During use, there is an unavoidable situation in which the attachment point 11b rotates relative to the vaginal wall 4. In the first configuration form described above, the extension of the attachment range 03 allows contact with the vaginal wall 4 through a structure that resembles a "bow" shape, thereby appropriately solving the above problem. Specifically, in the second configuration, in the form in which the pasting end is a part of a sphere, the connection point of the base portion 11a of each pulled-out end 11 can be pasted to the vaginal wall 4 as an additional pasting point. In the case shown in FIG. 6, the expandable body 1 is rotated to one side limit position inside the vagina. In this state, a new pasting point 11b-6 is formed at the connection point of the base portion 11a of each pulled-out end 11, thereby restricting continued rotation. In this state, the pressing force of the pasting point 11b-6 against the vaginal wall 4 is smaller than the pressing force of the pasting points 11b-1 to 11b-3 against the vaginal wall 4, so that the pasting point 11b cannot play a role in positioning the auxiliary pasting device, and serves only to prevent rotation.

[0062] When the extension body 1 rotates, the force generating part 3 inevitably changes position, but due to limitations in intravaginal space, the amount of change in position does not affect the length located outside the human body, and in order to better improve the comfort of use, it is preferable that a smoother structure be realized even at the connection points of the base parts 11a of each pull-out end 11.

[0063] When the number of pull-out ends 11 is more than three, the effect achieved is roughly the same as when there are three, but the effect is similar for the form having two pull-out ends 11, except that there are two clearly distinguishable rotation directions only in the rotation direction of the extension body 1. The first is rotation in the distribution direction of the two pull-out ends 11 as shown in Figure 7, and the second is rotation to both sides of the distribution direction of the two pull-out ends 11 as shown by the arrow directions in Figure 5, where the distribution direction is the planar direction shown in Figure 7, and it goes without saying that in either direction, the degree of rotation can be limited by the bonding point 11b11-7 shown in Figure 7.

[0064] When the pasted end is a partial ring, as shown in FIG. 8, the technical objective achieved is the same as that of a partial sphere, with the difference being the difference in the contact location, that is, the ring shape can obtain a larger contact area with the circumferential direction of the vaginal wall 4, and the difference from the curvature direction of the curved structure is that the curvature of the ring here is perpendicular to the vaginal entry direction, while the curvature of the complete structure is along the vaginal entry direction.

[0065] In this embodiment, the cross section of the ring-shaped body is preferably circular or elliptical, or at least needs to be ensured that the side facing the vaginal wall 4 is curved, which ensures comfort when pressed against the vaginal wall 4, while the shape of the other side allows for a wider range of options since it does not come into direct contact with the human body.

[0066] In order to realize the limitation of the rotation angle by the connection point of the root portion 11a of the pull-out end 11, the length of the pull-out end 11 can be appropriately extended to realize the restriction of the rotation limit at a smaller rotation angle, and the length limit may be selected based on the degree of comfort that the human body can sense.

[0067] In another preferred form of this embodiment, the expansion body 1 is a hollow deformable structure, the adjustment system 2 is used to maintain the expansion body 1 in a first state 01, and in the first state 01, the internal cavity of the expansion body 1 is compressively deformed, and in the second state 02, the compressed internal cavity is at least partially restored, and the biasing portion 3 is connected to one end of the expansion body 1.

[0068] In the above embodiment, the expandable body 1 may be made of elastic and non-absorbent materials such as medical silicone resin structure, plastic structure, or metal structure, and the material may apply pressure to the vaginal wall 4, and the urging force may be a deformation restoring force due to bending or a deformation restoring force due to compression deformation. Obviously, in the above-mentioned embodiment with the pull-out end 11, the elastic restoring force due to bending is a factor for fixing the expandable body 1 to the vaginal wall 4, but in the embodiment with a deformable structure, the elastic restoring force due to compression deformation is a factor for fixing the expandable body 1 to the vaginal wall 4, and the compression deformation and bending can occur simultaneously, and the common elastic restoring force of both can also ensure stable fixation of the expandable body 1.

[0069] The deformable structure is an elastic structure that has a maximum dimension in a central portion that enters the vaginal direction and gradually contracts and expands on both sides, the length in the direction of extension being greater than the maximum width in the central portion.

[0070] The contraction on both sides of the deformable structure may be symmetric or asymmetric, uniform or non-uniform, where an ellipsoidal shape is the preferred form, and the long axis direction of the ellipsoidal shape is the direction of insertion into the vagina, which is also the extension direction referred to here, and as shown in FIG. 9, the gentler side walls around the short axis allow for a larger bonding area with the vaginal wall 4, and in this embodiment, the cavity portion of the deformable structure is used to accommodate deformation after the outside is pressed and reduce the weight of the entire expandable body 1.

[0071] Here, the side wall of the expansion body 1 is provided with a plurality of through-hole regions, which are a plurality of through-hole grooves 12 distributed along the length direction of the deformable structure. The provision of the grooves 12 facilitates the process of the expansion body 1 achieving the first state 01 with respect to the adjustment system 2, while at the same time making the pressure inside and outside the vagina relatively consistent during the process of entering the vagina, thus avoiding the problem of difficult entry caused by localized high pressure.

[0072] In the above embodiment, the pressure of the expansion body 1 against the vaginal wall 4 is due to its own deformation or the compressibility of the material, etc., and the pressing force is generated by the expansion body itself. However, in order to further improve the pressing effect against the vaginal wall 4, a preferred form is provided in which a pair of opposite-type permanent magnets are provided in opposing directions on the inner wall of the expansion body 1, and the opposing directions are the directions toward which the expansion body is inserted into the vagina.

[0073] As shown in FIG. 15, a set of opposite-sex permanent magnets includes a first permanent magnet 51 and a second permanent magnet 52, which are attracted to each other, with the attractive force being in the direction of F1 in the figure. When the deformable structure is an ellipsoidal spherical structure, a set of such structures can be provided on both sides of the major axis of the ellipsoidal spherical structure, so that the deformable structure can be pressed against it to generate an effect of extending in the circumferential direction of the minor axis. This effect is of course advantageous for fixation inside the vagina.

[0074] The installation of the hetero-polar permanent magnets can be applied to many shapes, of which the elliptical spherical shape is a relatively preferred configuration. Furthermore, any configuration that can generate a restoring force after elastic deformation and that deforms due to the mutual attraction of the two magnets when the hetero-polar permanent magnets are installed is included in the scope of the present invention.

[0075] In this embodiment, as a form for implementing the following invention in which the adjustment system 2 maintains the first state 01 of the expansion body 1, as shown in Figures 10 and 11, the adjustment system 2 includes an outer tube body 21 and a push rod 22, one end of the outer tube body 21 is an open end 21a, and the expansion body 1 is at least partially inserted into the outer tube body 21 on the side of the open end 21a, and the other end of the outer tube body 21 is from which the biasing portion 3 is pulled out, and the push rod 22 is inserted from the end of the outer tube body 21 pulled out from the biasing portion 3, and the expansion body 1 is pulled out from the open end 21a by the action of the push rod 22.

[0076] During use, the expansion body 1 is inserted into the vagina using the adjustment system 2, and after the position of the end of the outer tube body 21 is determined, the push rod 22 is pressed to push the expansion body 1 from the top of the opening end 21a, causing the expansion body 1 to become free and reach the second state 02, after which the adjustment system 2 can be removed from the vagina.

[0077] In the above process, the user's hand is always located outside the human body, which is more hygienic, but in the process of designing the structure of the adjustment system 2, the shape of the outer tube 21 can be optimized to provide greater comfort to the human body during the process of entering the vagina. Figure 11 shows a case where the entire expandable body 1 is located inside the outer tube 21, and in this case, the pull-out end 11 is more suitable for the curved structure of the buckle.

[0078] In a preferred embodiment, the opening end 21a is opened on the curved outer surface 21c of the outer tube body 21. This allows the outer tube body 21 to be softer during the process of entering the human body, and due to the curved shape, the annular edge 21b of the opening end 21a retracts inward relative to the vaginal wall 4 after the outer tube body 21 is inserted into the vagina, forming a distance H between the opening end 21a and the vaginal wall 4 as shown in Fig. 12. This distance H prevents the expandable body 1 from coming into contact with the vaginal wall 4 as much as possible during the process of changing state during the process of pulling the expandable body 1 out of the outer tube body 21, and this embodiment can also further improve the comfort of use.

[0079] Due to the optimized angle of the inner wall, the inner wall of the outer tube body 21 transitions to the edge of the opening end 21a due to contraction of the curved surface. This allows the user to insert the expandable body 1 into a predetermined position in the vagina with a smaller biasing force in the process of removing the expandable body 1 from the outer tube body 21, as shown in Figures 11 and 12.

[0080] The configuration of the outer tube body 21 in this embodiment is involved in the placement process of the expandable body 1 as a guide part, that is, in addition to maintaining the first state 01 of the elastic expandable body, it also plays the role of a carrier. Regarding the selection of material, the outer tube body 21 may be an elastic and non-absorbent structure such as a medical silicone resin structure, a plastic structure, or a metal structure.

[0081] Here, the side wall of the outer tube body 21 is a continuous or openwork structure. Of course, in order to ensure the comfort of use, the outer wall of the outer tube body 21 is preferably smooth, and after being inserted into the human body and set, the length must still be sufficient for the user to perform the operation of pushing the push rod 22 outside the human body. Whether continuous or openwork, the smooth purpose can be achieved and each has its own advantages. If the side wall is continuous, as shown in Figures 10 and 11, it is more convenient to process, and if the adjustment system 2 is not a disposable product, it is more convenient in terms of cleaning difficulties. If the side wall is openwork, the openwork pattern can be selected according to actual needs, but in the process of entering the vagina, the gas in the vagina can better circulate through the openwork part, thereby maintaining the pressure in the space and avoiding the resistance caused by local high pressure due to the entry of the adjustment system 2.

[0082] FIG. 13 shows a case where a part of the expandable body 1 is located inside the outer tube body 21. In this case, the pull-out end 11 is adapted to a shape including a curved structure and a bonding end, where the bonding end is located outside the outer tube body 21 as the tip 11c. In this case, the bonding end will inevitably come into contact with the vaginal wall 4 during the process of entering the vagina. In the process of the vaginal wall 4 being appropriately expanded and retained, and reaching a predetermined position and being pushed by the push rod 22, the effective support of each bonding point 11b against the vaginal wall 4 is gradually realized with the removal of the base part 11a, and then the adjustment system 2 can be removed. In this case, the size of the adjustment system 2 can be reduced, and the discomfort during insertion can be alleviated to a certain extent.

[0083] As shown in Figure 14, the form in which the expandable body 1 of the deformable structure is attached to the adjustment system 2 is shown, and during specific use, the use form is the same as that of the structure shown in Figures 11 and 13, so the description is omitted here.

[0084] Regarding the improvement to the outer tube 21 and the push rod 22, the inner wall of the outer tube 21 performs linear guidance for the push rod 22, and such a form is not limited to the shape of the outer wall of the outer tube 21, and linear guidance is the simplest for the user to perform the pushing action, and it is sufficient to ensure that the bonding portion 11b can extend along a linear direction by simply bonding the outer wall of the push rod 22 to the inner wall of the outer tube 21. In order to facilitate the operation of the biasing part 3, the push rod 22 has a hollow structure, and the hollow part is for the biasing part 3 to pass through, making it easier to operate.

[0085] Regarding the placement of the opening end 21a, the present invention includes two embodiments: a first embodiment in which the opening end 21a is in a normally-on state, and a second embodiment in which the outer tube body 21 is an elastic body, the opening end 21a is in a normally-off state, and is turned on by the action of an external pressing force.

[0086] Figures 10 to 14 show opening end 21a in a normally on state, but to ensure cleanliness before use, an opening end 21a that is normally off and turns on under set conditions may be further provided, and as shown in Figure 16, a relatively simple opening end 21a in a normally off state is shown, and by opening a through hole in the complete structure, it is possible to allow the expansion body 1 to pass through by opening the through hole.

[0087] Here, the cross-intersection shape is a normal shape, that is, a shape in which two through marks shown in FIG. 16 intersect; of course, shapes in which more through marks intersect are also included in the scope of the present invention; in such a shape, an elastic material for the outer tube body 21 is a necessary condition, the through marks are obtained by cutting, and a normally-off state can be achieved by bonding both sides of the mark together, but the on process only needs to be achieved by deformation of the through marks, and the direction of the arrow in FIG. 16 is the deformation direction. EXAMPLES

[0088] In the above-mentioned Example 1, the adjustment system 2 maintains the first state 01 of the expansion body 1, but when it is separated from the expansion body 1, the expansion body 1 naturally changes to the second state 02. In this example, the adjustment system 2 is used to release the first state 01 of the expansion body 1, and the first state 01 is maintained by the biasing force of the user's hand, i.e., an external force described later.

[0089] In this embodiment, an auxiliary pressure device is provided that requires the user's hand to enter the vagina, and as shown in FIG. 17, the direction of the arrow of force F indicates the direction of force applied to the withdrawal end 11 of the hand, and by bringing the tips 11c closer together, it becomes easier for the hand to enter the vagina.

[0090] The expansion body 1 includes at least two pull-out ends 11 uniformly distributed along the circumferential direction, with the root portions 11a of each pull-out end 11 connected and the tips 11c being free ends, and the adjustment system 2 is used to release the first state 01 of the expansion body 1 to reach the second state 02, in which in the first state 01 the tips 11c approach or stick together due to the action of an external force, and in the second state 02, the external force is released and the tips 11c move away from each other due to the action of the adjustment system 2, and the biasing portion 3 is connected to the connection points of each pull-out end 11.

[0091] In this form, after the force F is released, the tips 11c of each pull-out end 11 are moved away from each other by the adjustment system 2, where the pull-out ends 11 are elastic and / or the connection points of each pull-out end 11 are elastic, and due to the elasticity of the above structure, the pull-out ends 11 themselves are elastically deformed and / or the connection points of each pull-out end 11 are elastically deformed under the action of an external force, and after the external force by the user is released, a restoring force is generated due to recovery of the deformation, and this restoring force is advantageous for fixing the entire expansion body 1 to the vaginal wall 4, but in this embodiment, the above restoring force is not a factor in achieving fixation of the expansion body 1 to the vaginal wall 4, but only plays an auxiliary role.

[0092] In such a case or when the pull-out ends 11 do not have the elasticity, in another preferred embodiment, the base portions 11a of the pull-out ends 11 are provided to rotate relative to one another. As shown in Fig. 19, even in this embodiment, it is possible to ensure that the pull-out ends 11 rotated relative to one another reach the second state 02, and the rotational installation form allows the relative positions of the pull-out ends 11 to change.

[0093] The relative rotational installation referred to here may be a rotational connection between two drawer ends 11 as shown in Figure 19, or all of the drawer ends 11 may be rotationally connected to an additional third structure, and the relative rotational installation between them is achieved by rotation relative to a third party.

[0094] Regarding the embodiment of the adjustment system 2, the following configuration is provided in this embodiment.

[0095] The first form of the adjustment system 2 is a set of homogeneous permanent magnets, which are provided in one-to-one correspondence with the tips 11c and are fixed to the tips 11c, and the homogeneous permanent magnets can be fitted into the tips 11c of each pull-out end 11, respectively.

[0096] Since the material of the extension body 1 itself in the present invention does not affect magnetism, it is possible to prevent discomfort to the human body during use, and the third permanent magnet 53 and the fourth permanent magnet 54 shown in Figure 18 are permanent magnet structures that require embedding.

[0097] During the processing process, it is preferable that the fitting positions of the permanent magnets are seamlessly connected, and the entire structure is considered to be one unit on the outside of the expansion body 1, which not only ensures safety of use, but also effectively improves the aesthetics of the product and brings a better user experience.

[0098] In order to ensure sufficient magnetism, it is necessary to ensure the size of the permanent magnet, and in order to ensure a sufficient mounting position, the fitting position of the permanent magnet can be appropriately increased. The bonding end in the above Example 1 can achieve this purpose, and at the same time, it is of course also possible to achieve the purpose of increasing the bonding area with the vaginal wall 4.

[0099] The optimization means for increasing the bonding area in the above-mentioned embodiment 1 can be similarly applied to this embodiment, and therefore a description thereof will be omitted here.

[0100] The second form of the adjustment system 2 is an elastic structure that is connected to each pull-out end 11 and can be deformed by pressing any of the pull-out ends 11. As shown in the schematic diagram of Fig. 20, one form in which the adjustment system 2 achieves elasticity is shown, and the adjustment system 2 is connected to the pull-out ends 11 through elastic protruding positions that correspond one-to-one with the pull-out ends 11. Note that the broken line structure in the figure only shows the form of the elastically deformable structure, and may be any form such as a spring structure, a rubber structure, or a compressible airbag. Since each pull-out end 11 is attached to the vaginal wall 4, there is no difference in the deformation of the elastic structure in the direction toward each pull-out end 11, and it is necessary to ensure the same use in each direction.

[0101] During the process of the user's hand applying pressure to the pull-out ends 11, the elastic structure deforms to allow each pull-out end 11 to approach each other, resulting in a first state 01, but when the external force is released, the elastic deformation returns to its original state, acting on the extension body 1 and enabling the extension body to reach a second state 02.

[0102] In a third form of the adjustment system 2, the expansion body 1 is a hollow deformable structure, and the adjustment system 2 is used to release the first state 01 of the expansion body 1 to reach a second state 02, in which in the first state 01, the deformable structure causes the internal cavity of the expansion body 1 to be compressed and deformed under the action of an external force, and in the second state 02, the external force is released and the internal cavity is at least partially restored under the action of the adjustment system 2, and the biasing member 3 is connected to one end of the expansion body 1.

[0103] As shown in FIG. 21, the deformable structure of the expandable body 1 is shown, and similarly, the contraction on both sides of the deformable structure may be symmetric or asymmetric, uniform or non-uniform, where an ellipsoidal shape is a preferred form, and the advantages of the ellipsoidal shape are as described in Example 1 above, and will not be described here.

[0104] In a specific optimized form, the deformable structure is an elastic structure that has a maximum dimension at the central part inserted in the vaginal direction, and gradually contracts and extends on both sides, the length in the extending direction is greater than the maximum width of the central part, multiple homogeneous permanent magnets are provided on the inner wall of the expandable body 1, the homogeneous permanent magnets are uniformly distributed around the central part of the deformable structure, and the external force acts on the outer wall of the central part.

[0105] Similarly, referring to Figure 21, force F in the figure indicates the direction of the external force from the user, and F1 in the figure indicates the force with which the permanent magnets repel each other, ensuring sufficient adhesion between the expandable body 1 and the vaginal wall 4.

[0106] In this embodiment, the expansion body 1 may have an elastic structure and generate a pressing effect against the vaginal wall 4 through a certain restoring force due to its elastic return; similarly, in this embodiment, the above-mentioned restoring force is not a factor in achieving fixation of the expansion body 1 to the vaginal wall 4, but only serves an auxiliary role.

[0107] As in the above embodiment, the elastic structure of the elliptical spherical structure is a preferred form, and of course, the hand drum shape or other isomeric structures that satisfy the above conditions are also included in the scope of the present invention. Taking the elliptical spherical shape as an example, the long axis direction of the elliptical spherical shape is the direction of insertion into the vagina, and considering the characteristic of the elliptical spherical shape having long and short axes and the action direction of the isomeric permanent magnet, even if a certain deflection occurs during the process of insertion into the vagina, the set directions of the long and short axes can be naturally adjusted within the vagina, and the desired effect can be achieved with respect to the pressure on the vaginal wall 4.

[0108] As a fourth form of the adjustment system 2, the deformable structure is an elastic structure that has its maximum dimension at the central part that is inserted toward the vagina and gradually contracts and extends on both sides, and its length in the extension direction is greater than the maximum width at the central part, one end of the biasing part 3 is connected to the inner wall of the internal cavity, the connection point is located at one end of the longitudinal direction of the deformable structure, and the other end of the biasing part 3 penetrates the other end of the internal cavity, the adjustment system 2 includes a positioning block 23 fixed to the biasing part 3, and the positioning block 23 includes a waiting-for-use state in which it is located in the internal cavity, and a positioning state in which it is located outside the internal cavity and pressed against the outer wall of the expansion body 1 to remain attached, and the transition from the waiting-for-use state to the positioning state is made by the process of maintaining the position of the expansion body 1 in the vagina by an external force and pulling the biasing part 3 by an external force.

[0109] In this embodiment, the adjustment system 2 achieves the above-mentioned optimization means for the purpose of releasing the first state 01 of the expansion body 1. Specifically, after the expansion body 1 reaches a predetermined position, the biasing part 3 is pulled to achieve biasing at the connection point with the internal cavity, causing elastic deformation in the expansion body 1, and the deformation process occurs in a direction perpendicular to the biasing part 3 to bias the expansion body 1, which is the pressing direction against the vaginal wall 4. By controlling the position of the positioning block 23, the final degree of deformation is controlled, and the pressing force against the vaginal wall 4 is controlled.

[0110] In order to ensure that the positioning block 23 can be attached to the outer wall of the expansion body 1 outside the internal cavity, the elastic structure of the deformable structure is pressed when passing through the through position, deforming the through position to pass through, and the deformation is restored after passing, thereby stopping the positioning block 23 outside the elastic structure.

[0111] In order to better realize the stopper effect, the exterior of the positioning block 23 gradually shrinks along the direction of removal from the internal cavity. The truncated cone shape shown in Fig. 23 is one embodiment of the present invention. Meanwhile, the hole position for removing the positioning block 23 in the expansion body 1 can adopt the same shrinkage form and direction as the positioning block 23, so as to achieve guidance while ensuring stable positioning of the exterior of the positioning block 23.

[0112] At least two positioning blocks 23 are arranged side by side at intervals in the direction of removal from the internal cavity in the biasing section 3. This makes it possible to adjust different pressing forces against the vaginal wall 4 by bonding different positioning blocks 23 to the outer wall of the expandable body 1. EXAMPLES

[0113] In this embodiment, the adjustment system 2 does not independently achieve the retention or release of the first state 01, but simultaneously achieves the above two technical objectives; specifically, the expandable body 1 is a hollow deformable structure, the adjustment system 2 is used to retain and release the first state 01 of the expandable body 1, and in the first state 01, the internal cavity of the expandable body 1 is compressed and deformed, and in the second state 02, the compressed and deformed internal cavity is at least partially restored, and the biasing part 3 is connected to one end of the expandable body 1, which is different from the above embodiment.

[0114] In this embodiment, the deformable structure is an elastic structure that has a maximum dimension at the central portion that is inserted toward the vagina and gradually contracts and extends on both sides, the length in the extending direction is greater than the maximum width at the central portion, one end of the biasing portion 3 is connected to the inner wall of the internal cavity, the connection point is located at one end of the long axis of the oval sphere, and the other end of the biasing portion 3 passes through the internal cavity and is located at the other end of the long axis. The adjustment system 2 includes an outer tube 21 and a push rod 22, one end of the outer tube 21 is an open end 21a, and the expansion body 1 is at least partially inserted into the outer tube 21 on the side of the open end 21a, and the other end of the outer tube 21 is from which the biasing part 3 is pulled out, and the push rod 22 is inserted from the end of the outer tube 21 pulled out from the biasing part 3, and the expansion body 1 is removed from the open end 21a by the action of the push rod 22. The adjustment system 2 further includes a positioning block 23 fixed to the biasing part 3, and the positioning block 23 includes a waiting-for-use state in which it is located in the internal cavity, and a positioning state in which it is located outside the internal cavity and pressed against the outer wall of the expansion body 1 to remain attached, and the transition from the waiting-for-use state to the positioning state is made by the process of maintaining the position of the outer tube 21 and / or the push rod 22 and the attached state with the expansion body 1 by an external force, and pulling the biasing part 3 by an external force.

[0115] 22 and 23, the outer tube body 21 and the push rod 22 in this embodiment have the same functions as those in the first embodiment and may adopt the same optimized form, and the positioning block 23 has the same functions as those in the second embodiment and may adopt the same optimized form, and the optimized form in the first embodiment will not be described again here. The difference is that it needs to play the role of holding the position of the expansion body 1 when it is inserted into the vagina and the expansion body 1 is attached to the outer tube body 21. EXAMPLES

[0116] In this embodiment, compared with the third embodiment, a different regulating system 2 is adopted. Specifically, the regulating system 2 is a pressure system using gas or liquid as a medium, and includes a conveying pipe 61 and a valve body structure 62. The conveying pipe 61 connects the internal cavity of the expansion body 1 with the external space. The valve body structure 62 is attached to a part of the conveying pipe 61 located in the external space, and turns on and off the internal passage of the conveying pipe 61.

[0117] In the implementation process, the input and extraction of the medium from the conveying channel 61 can be achieved by a structure such as an external syringe, where the injection of the medium is carried out after the expandable body 1 enters the vagina in the first state 01, to ensure that a part of the conveying channel 61 is located outside the vagina, and the adjustment of the pressing force against the vaginal wall 4 needs to be achieved by adjusting the amount of medium injected. The selected valve body structure 62 may be unidirectional to ensure the entry of the medium, and when the auxiliary pressure device is pulled out from the vagina, it is only necessary to ensure the pressure of the medium when it is inserted, or the valve body structure 62 may be bidirectional, and when use is completed, the medium is sucked out and then the auxiliary pressure device is removed from the vagina.

[0118] Here, the valve body structure 62 may be provided at a position close to the expansion body 1, and as the expansion body 1 enters the vagina, the expansion action of the expansion body 1 on the vagina causes the inside of the vagina to partially expand to accommodate the location of the valve body structure 62, thereby avoiding causing discomfort outside the human body.

[0119] In order to increase the frictional force with the vaginal wall 4, any of the outer surfaces of the deformable structures in the above embodiments of the present invention may be provided with a suitable anti-slip structure to ensure positional stability; of course, surface protrusion is the preferred embodiment, and the width of the protrusion should be effectively controlled to avoid discomfort.

[0120] In this embodiment, the outer tube 21 and the push rod 22 may assist the advancement of the expansion body, and as a part of the adjustment system 2, the optimized form is of course the same as in the first embodiment.

[0121] The above describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the above embodiments and the description are merely for the purpose of illustrating the principles of the present invention, and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and all of these modifications and improvements are included within the scope of the present invention.
