[0072] Embodiment 1

[0073] As Figure 1 shown, this embodiment provides a training device for pelvic floor rehabilitation and anal dilation training, aiming to effectively relieve sphincter spasm or improve the tension and elastic recovery of the pelvic floor muscles.

[0074] In some embodiments, the training device has a first direction X, which includes a flexible body 10 and at least one flexible sleeve 30; wherein, one end of the flexible body 10 is provided with a suction cup 13, and the suction cup 13 can be used to fix the flexible body 10 on other objects, improving the stability of the use of the training device and facilitating the operation and use by the user; along the first direction X, the diameter of the flexible body 10 gradually decreases from the end close to the suction cup 13 to the end far from the suction cup 13, so that the flexible body 10 has a conical structure, which is conducive to the training device reaching the sphincter or pelvic floor muscle part more easily, thereby realizing the training of the sphincter or pelvic floor muscle; the at least one flexible sleeve 30 is configured to be able to be sleeved on the outer periphery of the flexible body 10 along the first direction X, and the flexible sleeve 30 and the flexible body 10 are in negative tolerance fit, which can prevent the flexible sleeve from falling off during use, and the flexible sleeves are sleeved on the flexible body in the way of "Russian nesting dolls", reducing the space occupied by the training device, shrinking the packaging volume, and being convenient for carrying, transporting and storing.

[0075] In some embodiments, the maximum diameter D1 of the flexible body 10 satisfies: 2 cm ≤ D1 ≤ 5 cm to meet the needs of different groups.

[0076] In some embodiments, the length L1 of the flexible body 10 along the first direction X satisfies: 6 cm ≤ L1 ≤ 15 cm to meet the needs of different groups.

[0077] In some embodiments, the training device has a second direction Y intersecting the first direction X. Preferably, there are three flexible sleeves 30, and the three flexible sleeves 30 can be sleeved on the flexible body 10 in the way of "Russian nesting dolls", so as to realize the adjustment of the size of the training device to meet different use requirements.

[0078] Exemplarily, the three flexible sleeves 30 are respectively a first flexible sleeve 31, a second flexible sleeve 32, and a third flexible sleeve 33. Among them, the first flexible sleeve 31, the second flexible sleeve 32, and the third flexible sleeve 33 can be sequentially sleeved on the flexible body 10 in the way of nested dolls; specifically, the first flexible sleeve 31 is configured to be sleeved on the outer periphery of the flexible body 10 sequentially along the first direction X, the second flexible sleeve 32 is configured to be sleeved on the outer periphery of the first flexible sleeve 31 along the first direction X, and the third flexible sleeve 33 is configured to be sleeved on the outer periphery of the second flexible sleeve 32 along the first direction X. The three flexible sleeves 30 can be nested on the flexible body 10 in the way of "nested dolls", which is convenient for users to flexibly adjust the size of the training device according to actual needs. For example, increasing the flexible sleeves 30 gradually increases the size of the training device, or removing the flexible sleeves 30 gradually reduces the size of the training device.

[0079] Adopting the nested doll design, it is no longer necessary to arrange multiple physical structures of different sizes, which can effectively reduce the material usage and lower the material cost; and adopting the nested doll design can reduce the space occupied by the training device, reduce the packaging volume, and facilitate carrying, transportation and storage.

[0080] In some embodiments, in the same cross-section in the second direction Y, the diameters of the first flexible sleeve 31, the second flexible sleeve 32, and the third flexible sleeve 33 increase in sequence to meet the requirement that the first flexible sleeve 31, the second flexible sleeve 32, and the third flexible sleeve 33 can be nested on the flexible body 10 in the way of "nested dolls", which is convenient for users to flexibly adjust the size of the training device according to actual needs.

[0081] It should be noted that in the above terms, the second direction Y is perpendicular to and intersects the first direction X. The first direction X is the axial direction, and the second direction Y is the radial direction.

[0082] In some embodiments, the first flexible sleeve 31, the second flexible sleeve 32, and the third flexible sleeve 33 are all made of food-grade silicone material by one-time molding to meet the safety and hygiene requirements.

[0083] In some embodiments, the connection between the flexible body 10 and the first flexible sleeve 31, between the first flexible sleeve 31 and the second flexible sleeve 32, and between the second flexible sleeve 32 and the third flexible sleeve 33 are all connected with negative tolerance fit, so that there is a certain negative tolerance tight fit degree between the flexible body 10 and the flexible sleeve, and between the flexible sleeves, effectively avoiding the flexible sleeve from falling off during use, improving the convenience of use, and not affecting the tightened state of the inner flexible sleeve when removing the outermost flexible sleeve.

[0084] In some embodiments, the first flexible sleeve 31 has a third opening 311 to facilitate the first flexible sleeve 31 being sleeved on the flexible body 10. Along the first direction X, the diameter of the first flexible sleeve 31 gradually decreases from the end close to the third opening 311 to the end far from the third opening 311 to match the shape of the flexible body 10, so that the inner wall of the first flexible sleeve 31 can completely fit the outer peripheral wall of the flexible body 10, ensuring the training effect.

[0085] Similarly, the second flexible sleeve 32 has a fourth opening 321 to facilitate the second flexible sleeve 32 being sleeved on the first flexible sleeve 31. Along the first direction X, the diameter of the second flexible sleeve 32 gradually decreases from the end close to the fourth opening 321 to the end far from the fourth opening 321 to match the shape of the first flexible sleeve 31, so that the inner wall of the second flexible sleeve 32 can completely fit the outer peripheral wall of the first flexible sleeve 31, ensuring the training effect.

[0086] Similarly, the third flexible sleeve 33 has a fifth opening 331 to facilitate the third flexible sleeve 33 being sleeved on the second flexible sleeve 32. Along the first direction X, the diameter of the third flexible sleeve 33 gradually decreases from the end close to the fifth opening 331 to the end far from the fifth opening 331 to match the shape of the second flexible sleeve 32, so that the inner wall of the third flexible sleeve 33 can completely fit the outer peripheral wall of the second flexible sleeve 32, ensuring the training effect.

[0087] In some embodiments, to facilitate removing the first flexible sleeve 31, a second turned-out edge 312 is provided at one end of the first flexible sleeve 31 close to the third opening 311.

[0088] Similarly, to facilitate removing the second flexible sleeve 32, a third turned-out edge 322 is provided at one end of the second flexible sleeve 32 close to the fourth opening 321.

[0089] Similarly, to facilitate removing the third flexible sleeve 33, a fourth turned-out edge 332 is provided at one end of the third flexible sleeve 33 close to the fifth opening 331.

[0090] In some embodiments, the wall thickness H1 of the first flexible sleeve 31, the wall thickness H2 of the second flexible sleeve 32, and the wall thickness H3 of the third flexible sleeve 33 satisfy: H1 < H2 < H3, so that the size of the training device can increase or decrease step by step, thus meeting the usage requirements without manufacturing multiple physical structures of different sizes, thereby saving the usage amount of materials and reducing the material cost.

[0091] In some embodiments, the wall thickness H1 of the first flexible sleeve 31 satisfies: 0.5 mm ≤ H1 ≤ 2.5 mm;

[0092] In some embodiments, the wall thickness H2 of the second flexible sleeve 32 satisfies: 1.5 mm ≤ H2 ≤ 3.5 mm;

[0093] In some embodiments, the wall thickness H3 of the third flexible sleeve 33 satisfies: 2.5 mm ≤ H3 ≤ 4.5 mm.

[0094] In some embodiments, the flexible body 10 is preferably a solid medical-grade silicone rubber, so as to be able to provide a certain supporting effect and ensure that the training device can enter the specified part for training.

[0095] Example 2

[0096] This example provides a training device, which is different from Example 1 in that:

[0097] As Figure 2 shown, a first cavity 11 extending along the first direction X is provided inside the flexible body 10 of this example, and a counterweight 40 is provided in the first cavity 11. By providing the counterweight 40, it can play a supporting role for the flexible body 10, so that the flexible body 10 has a certain hardness, reduce the deformation of the flexible body, and is beneficial for the flexible body 10 to enter the specified position to train the muscles, thereby improving the training efficiency and effect; it should be noted that the counterweight 40 can be a block structure or a columnar structure, and no specific limitation is made here. It should be understood that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.

[0098] Example 3

[0099] As Figures 3 - 12 shown, this Example 3 provides a training device, which is different from Example 1 in that:

[0100] The training device of this example further includes a vibration mechanism 20.

[0101] In a specific embodiment, a first cavity 11 extending in a first direction X is provided inside the flexible body 10. The first cavity 11 has a first opening 12. A suction cup 13 is provided at one end of the flexible body 10 close to the first opening 12. By providing the suction cup 13 at the end of the flexible body 10, the flexible body 10 can be fixed to other objects by using the suction cup 13, improving the stability of the training device during use and facilitating the operation and use by the user; the vibration mechanism 20 is arranged in the first cavity 11. The vibration mechanism 20 includes a housing 21, at least one set of vibration components 23 arranged inside the housing 21, and a flexible button 22 arranged at the end of the housing 21. The flexible button 22 is configured to be able to abut against the inner wall of the suction cup 13 and block the first opening 12; by arranging the vibration mechanism 20 inside the flexible body 10, the vibration components 23 can be used to vibrate and massage muscle tissues during training, which can effectively relieve sphincter spasm or improve the tension and elastic recovery of the pelvic floor muscles, improving the training effect; the flexible body 10 is provided with the first opening 12 to facilitate the installation of the vibration mechanism 20. By providing the flexible button 22 at the end of the housing 21, on the one hand, the first opening 12 can be blocked, making the first cavity 11 form a closed space, playing a role in protecting the vibration mechanism 20; on the other hand, after the flexible button 22 blocks the first opening 12, the suction cup 13 can form a semi-closed structure, which is beneficial to the stable fixation of the suction cup 13 on other objects, facilitating the operation and use by the user.

[0102] In some embodiments, due to different user requirements and application scenarios, in order to be able to adjust the size of the flexible body 10, for this purpose, the training device further includes at least one flexible sleeve 30. The at least one flexible sleeve 30 is configured to be able to be sequentially sleeved on the outer periphery of the flexible body 10 along the first direction X, so as to realize the adjustment of the size of the flexible body 10 to meet the needs of different users.

[0103] Specifically, the design of the at least one flexible sleeve 30 can be sleeved on the flexible body 10 in a "matryoshka" way, which is convenient for the user to flexibly adjust the size of the training device according to actual needs. For example, increasing the flexible sleeve 30 gradually increases the size of the training device, or removing the flexible sleeve 30 gradually reduces the size of the training device; adopting the matryoshka design, there is no need to arrange multiple physical structures of different sizes, which can effectively reduce the material usage and lower the material cost; and adopting the matryoshka design can reduce the space occupied by the training device, reduce the packaging volume, and is convenient for carrying, transportation and storage.

[0104] It should be noted that the meaning of the above term "at least one" is more than one, for example, it can be one, two, three, four, five or even more, unless otherwise clearly and specifically defined.

[0105] In some embodiments, to ensure the normal operation of the vibration assembly 23, the housing 21 is preferably a rigid plastic housing, and the rigid plastic housing can support the flexible body 10 to reduce the deformation amplitude of the flexible body 10 in the axial and radial directions, thereby improving the training effect.

[0106] In another embodiment, since the housing 21 is preferably a rigid plastic housing, to facilitate the installation of the vibration mechanism 20 into the first cavity 11 of the flexible body 10 through the first opening 12, the flexible body 10 is preferably a medical-grade silicone. The medical-grade silicone has a certain deformation ability and can meet the assembly requirements of the vibration mechanism 20. At the same time, the flexible button 22 can also abut against the opening of the flexible body 10 to form a seal, thereby playing a role in protecting the vibration mechanism 20.

[0107] In some embodiments, after the vibration mechanism 20 is installed inside the flexible body 10, to prevent the vibration mechanism 20 from axially or radially moving, a limiting groove 211 is provided on the outer wall of the housing 21, and a limiting boss 14 matching the limiting groove 211 is provided on the inner wall of the flexible body 10. After the vibration mechanism 20 is installed in the first cavity 11 of the flexible body 10, the limiting boss 14 is snapped into the limiting groove 211. By using the cooperation of the limiting boss 14 and the limiting groove 211, the axial and radial movement of the housing 21 can be restricted, thereby ensuring that the vibration mechanism 20 is relatively fixed to the flexible body 10 and guaranteeing the subsequent training effect.

[0108] It should be noted that in the above terms, "axial direction" refers to the first direction X, and "radial direction" refers to the direction perpendicular to the first direction X.

[0109] In some embodiments, the housing 21 is provided with a receiving cavity 212, and the vibration assembly 23 is arranged in the receiving cavity 212. In this embodiment, to improve the training effect, the vibration assembly 23 is preferably two groups, and the two groups of vibration assemblies 23 are arranged at intervals along the first direction X.

[0110] In some embodiments, to facilitate the installation and fixation of the flexible button 22, the receiving cavity 212 has a second opening 213, and the inner wall of the housing 21 at the second opening 213 forms a first step structure 214. The flexible button 22 is arranged on the first step structure 214. When the flexible body 10 is assembled into the first cavity 11 of the flexible body 10, the first step structure 214 and the inner wall of the suction cup 13 jointly limit and fix the flexible button 22, thereby ensuring that the flexible button 22 can block the first opening 12 and ensuring that the suction cup 13 can be firmly connected to other objects, which is convenient for the user to operate and use.

[0111] In some embodiments, one end of the housing 21 near the second opening 213 is provided with a first outward flanging 215. The first outward flanging 215 is connected to the first step structure 214. The first outward flanging 215 can play a role in limiting the flexible button 22, avoiding the radial movement of the flexible button 22. The first step structure 214 and the suction cup 13 can avoid the axial movement of the flexible button 22.

[0112] In some embodiments, the suction cup 13 is provided with an engaging block 131 extending into the first cavity 11 along the first direction X. A clamping groove 15 is formed between the engaging block 131 and the inner wall of the flexible body 10. Wherein, the first outward flanging 215 is clamped in the clamping groove 15, so that the housing 21 can be fixed in the first cavity 11 without falling off.

[0113] In some embodiments, to further ensure that the suction cup 13 can be stably fixed on other objects, it is necessary to ensure that the flexible button 22 and the suction cup 13 can be in an interference fit to form a semi-closed structure. For this purpose, the flexible button 22 is provided with a second step structure 222. An engaging groove 216 is formed between the inner wall of one end of the housing 21 near the second opening 213 and the second step structure 222. Wherein, the engaging block 131 is matched with the engaging groove 216. Thus, when the first outward flanging 215 is clamped in the clamping groove 15, the engaging block 131 abuts against the engaging groove 216 at the same time, thereby forming an interlocking structure. Applying pressure to the training device during training will not cause the flexible button 22 and the suction cup 13 to become disengaged, and further ensure that a vacuum state is formed inside the suction cup 13 to firmly adsorb on other objects.

[0114] In some embodiments, to improve the portability of the training device, the vibration mechanism 20 further includes a power source 24. The power source 24 is arranged in the accommodation cavity 212. The power source 24 is configured to be able to supply power to the vibration assembly 23, thereby improving the portability of the training device. It can use the vibration assembly 23 to vibrate and massage muscle tissues during training, which can effectively relieve sphincter spasm or improve the tension and elastic recovery of the pelvic floor muscles, and improve the training effect.

[0115] In some embodiments, the vibration mechanism 20 further includes a PCB board 25. The PCB board 25 is arranged in the accommodation cavity 212. The power source 24 is electrically connected to the PCB board 25. The PCB board 25 is provided with a control switch corresponding to the flexible button 22. The control switch is configured to be able to control the start-stop and frequency of the vibration assembly 23 when pressed, so as to facilitate the user to adjust the vibration frequency according to their own needs during use and ensure the training effect.

[0116] In some embodiments, the flexible button 22 is provided with a charging interface 221. The charging interface 221 is electrically connected to the PCB board 25. The charging interface 221 is configured to be able to charge the power source 24 to extend the service life of the training device.

[0117] In other embodiments, the charging interface 221 may also be arranged on the suction cup 13.

[0118] In other embodiments, the charging interface 221 may be any one of a Type-A interface, a Type-B interface, a Type-C interface, or a Lightning interface.

[0119] In some embodiments, the vibration assembly 23 includes a motor 231 and an eccentric block 232. The eccentric block 232 is provided at the output end of the motor 231. The motor 231 is connected to the power supply 24. The PCB board 25 can control the start / stop and rotation speed of the motor 231, and thus control the vibration frequency of the vibration assembly 23, facilitating the user to adjust according to their own needs during use to ensure the training effect.

[0120] In some embodiments, the rotation speed of the motor 231 is 6000 - 9000 r / min.

[0121] In some embodiments, the mass of the eccentric block 232 is 2 - 6 g, and the eccentric distance of the eccentric block 232 is 1 - 3 mm; this can avoid the vibration frequency being too large and affecting the training effect, and can also avoid the vibration frequency being too small to achieve the training effect.

[0122] In other embodiments, the vibration assembly 23 may also not be started according to the usage requirements to achieve the training effect of the "non-vibration" mode.

[0123] In some embodiments, the housing 21 is an integral structure.

[0124] In another embodiment, the housing 21 is a split structure. The housing 21 includes a first housing 21a and a second housing 21b.

[0128] In summary, by providing the suction cup 13 at the end of the flexible body 10, the present invention can fix the flexible body 10 on other objects by using the suction cup 13, improve the stability of the training device during use, and facilitate the operation and use by the user;

[0129] By providing the vibration mechanism 20 inside the flexible body 10, the vibration component 23 can be used to vibrate and massage the muscle tissue during the training process, which can effectively relieve sphincter spasm or improve the tension and elastic recovery of the pelvic floor muscles, and improve the training effect; the flexible body 10 is provided with a first opening 12 to facilitate the installation of the vibration mechanism 20, and by providing a flexible button 22 at the end of the housing 21, on the one hand, it can block the first opening 12, so that the first cavity 11 forms a closed space, playing a role in protecting the vibration mechanism 20; on the other hand, after the flexible button 22 blocks the first opening 12, the suction cup 13 can form a semi-closed structure, which is beneficial to the stable fixation of the suction cup 13 on other objects and is convenient for the user to operate and use;
