Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary exercise equipment technology, and in particular to a training device. Background Technology

[0002] For patients who have undergone hemorrhoid surgery, postoperative anal dilation exercises are often necessary to prevent anal stenosis or alleviate pain and difficulty in defecation caused by sphincter spasm. Patients with pelvic floor dysfunction also often require pelvic floor muscle training to restore muscle tone and elasticity.

[0003] Existing pelvic floor rehabilitation and anal dilation training devices typically employ multiple solid structures of different sizes. This design not only increases packaging size, material costs, and storage space, but also increases transportation costs, lacking portability and flexibility. Furthermore, the existing training devices have relatively simple structures and functions, failing to meet the diverse needs of different users. Utility Model Content

[0072] Example 1

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

[0074] In some embodiments, the training device has a first direction X, comprising 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, which can be used to fix the flexible body 10 to other objects, improving the stability of the training device and facilitating user operation and use; along the first direction X, the diameter of the flexible body 10 gradually decreases from the end closer to the suction cup 13 to the end farther away from the suction cup 13, making the flexible body 10 have a conical structure, which helps the training device to more easily reach the sphincter or pelvic floor muscles, thereby achieving training of the sphincter or pelvic floor muscles; the at least one flexible sleeve 30 is configured to be able to overlap the outer periphery of the flexible body 10 along the first direction X, the flexible sleeve 30 and the flexible body 10 have a negative tolerance fit, which can prevent the flexible sleeve from falling off during use, and the flexible sleeve is overlapped on the flexible body in a "matryoshka doll" manner, reducing the space occupied by the training device, reducing the packaging volume, and facilitating carrying, transportation and storage.

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

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

[0077] In some embodiments, the training device has a second direction Y intersecting the first direction X, and preferably three flexible sleeves 30. The three flexible sleeves 30 can be nested onto the flexible body 10 in a nesting manner, thereby realizing the adjustment of the size of the training device to meet different usage requirements.

[0078] For example, the three flexible sleeves 30 are a first flexible sleeve 31, a second flexible sleeve 32, and a third flexible sleeve 33, which can be sequentially nested onto the flexible body 10 in a matryoshka doll-like manner. Specifically, the first flexible sleeve 31 is configured to be sequentially nested onto the outer periphery of the flexible body 10 along the first direction X, the second flexible sleeve 32 is configured to be nested onto the outer periphery of the first flexible sleeve 31 along the first direction X, and the third flexible sleeve 33 is configured to be nested onto the outer periphery of the second flexible sleeve 32 along the first direction X. The three flexible sleeves 30 can be stacked onto the flexible body 10 in a matryoshka doll-like manner, allowing users to flexibly adjust the size of the training device according to actual needs, such as gradually increasing the size of the training device by adding flexible sleeves 30, or gradually decreasing the size of the training device by removing flexible sleeves 30.

[0079] The use of a nested design eliminates the need for multiple physical structures of different sizes, effectively reducing material usage and costs. Furthermore, the nested design reduces the space occupied by the training device, minimizing packaging volume and making it easier to carry, transport, and store.

[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 sequentially, so that the first flexible sleeve 31, the second flexible sleeve 32, and the third flexible sleeve 33 can be stacked on the flexible body 10 in a "matryoshka doll" manner, which makes it 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 terminology, the second direction Y intersects the first direction X perpendicularly, 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 in one piece to meet safety and hygiene requirements.

[0083] In some embodiments, the flexible body 10 and the first flexible sleeve 31, the first flexible sleeve 31 and the second flexible sleeve 32, and the second flexible sleeve 32 and the third flexible sleeve 33 are all connected with negative tolerance fit. This makes the flexible body 10 and the flexible sleeve, and the flexible sleeves have a certain negative tolerance tightness, which effectively prevents the flexible sleeves from falling off during use, improves the convenience of use, and does not affect the tightness of the inner flexible sleeves when the outermost flexible sleeve is removed.

[0084] In some embodiments, the first flexible sleeve 31 has a third opening 311 so that the first flexible sleeve 31 can be fitted onto the flexible body 10, and along the first direction X, the diameter of the first flexible sleeve 31 gradually decreases from the end near the third opening 311 to the end away 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 to ensure the training effect.

[0085] Similarly, the second flexible sleeve 32 has a fourth opening 321 so that the second flexible sleeve 32 can be fitted onto the first flexible sleeve 31. Along the first direction X, the diameter of the second flexible sleeve 32 gradually decreases from the end closer to the fourth opening 321 to the end farther away 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 fit completely with the outer peripheral wall of the first flexible sleeve 31 to ensure the training effect.

[0086] Similarly, the third flexible sleeve 33 has a fifth opening 331 so that the third flexible sleeve 33 can be fitted onto the second flexible sleeve 32. Along the first direction X, the diameter of the third flexible sleeve 33 gradually decreases from the end closer to the fifth opening 331 to the end farther away 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 fit completely with the outer peripheral wall of the second flexible sleeve 32 to ensure the training effect.

[0087] In some embodiments, to facilitate the removal of the first flexible sleeve 31, a second outward flange 312 is provided at the end of the first flexible sleeve 31 near the third opening 311.

[0088] Similarly, in order to facilitate the removal of the second flexible sleeve 32, the second flexible sleeve 32 is provided with a third outward flange 322 at the end near the fourth opening 321.

[0089] Similarly, in order to facilitate the removal of the third flexible sleeve 33, the third flexible sleeve 33 is provided with a fourth outward flange 332 at the end near 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 be increased or decreased step by step to meet the usage requirements, without the need to manufacture multiple physical structures of different sizes, thereby saving material usage and reducing material costs.

[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: 1.5mm ≤ H2 ≤ 3.5mm;

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

[0094] In some embodiments, the flexible body 10 is preferably solid medical-grade silicone to provide a certain support effect, ensuring that the training device can be inserted into the designated area for training.

[0095] Example 2

[0096] This embodiment provides a training device, which differs from Embodiment 1 in that:

[0097] like Figure 2 As shown, the flexible body 10 in this embodiment has a first cavity 11 extending along the first direction X. A counterweight 40 is provided in the first cavity 11. By setting the counterweight 40, the flexible body 10 can be supported, so that the flexible body 10 has a certain rigidity, reducing the deformation of the flexible body, which is conducive to the flexible body 10 entering the designated 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 column structure, and no specific limitation is made here. It should be understood that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principle of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.

[0098] Example 3

[0099] like Figures 3-12 As shown, this embodiment 3 provides a training device that differs from embodiment 1 in that:

[0100] The training device in this embodiment also includes a vibration mechanism 20.

[0101] In a specific embodiment, the flexible body 10 has a first cavity 11 extending along a first direction X. The first cavity 11 has a first opening 12. A suction cup 13 is provided at one end of the flexible body 10 near the first opening 12. By providing a suction cup 13 at the end of the flexible body 10, the flexible body 10 can be fixed to other objects, improving the stability of the training device and facilitating user operation and use. A vibration mechanism 20 is provided in the first cavity 11. The vibration mechanism 20 includes a housing 21, at least one set of vibration components 23 disposed within the housing 21, and a flexible button 22 disposed at the end of the housing 21. The flexible button 22 is configured to abut against the inner wall of the suction cup 13 and seal the first opening 12. By incorporating a vibration mechanism 20 within the flexible body 10, the vibration component 23 can be used to vibrate and massage muscle tissue during training, effectively relieving sphincter spasms or improving the tension and elasticity recovery of the pelvic floor muscles, thereby enhancing training effectiveness. The flexible body 10 has a first opening 12 to facilitate the installation of the vibration mechanism 20. By providing a flexible button 22 at the end of the housing 21, the first opening 12 can be sealed, forming a closed space in the first cavity 11, thus protecting the vibration mechanism 20. Furthermore, after the flexible button 22 seals the first opening 12, the suction cup 13 can form a semi-closed structure, which is beneficial for the suction cup 13 to be stably fixed on other objects, making it convenient for users to operate and use.

[0102] In some implementations, due to different user needs and application scenarios, in order to achieve the adjustment of the size of the flexible body 10, the training device further includes at least one flexible sleeve 30, which is configured to be sequentially stacked on the outer periphery of the flexible body 10 along the first direction X, thereby achieving the adjustment of the size of the flexible body 10 to meet the needs of different users.

[0103] Specifically, at least one flexible sleeve 30 is designed to be stacked on the flexible body 10 in a "matryoshka doll" manner, allowing users to flexibly adjust the size of the training device according to actual needs. For example, the size of the training device can be gradually increased by adding flexible sleeves 30, or the size of the training device can be gradually reduced by removing flexible sleeves 30. With the matryoshka doll design, it is no longer necessary to arrange multiple solid structures of different sizes, which can effectively reduce the amount of material used and reduce material costs. Moreover, the matryoshka doll design can reduce the space occupied by the training device, reduce the packaging volume, and facilitate carrying, transportation and storage.

[0104] It should be noted that the term "at least one" means one or more, such as one, two, three, four, five or even more, unless otherwise explicitly specified.

[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, in order 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 medical-grade silicone. Medical-grade silicone has a certain deformation capacity, which can meet the assembly 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 protecting the vibration mechanism 20.

[0107] In some embodiments, after the vibration mechanism 20 is installed inside the flexible body 10, in order to prevent the vibration mechanism 20 from moving axially or radially, the outer wall of the housing 21 is provided with a limiting groove 211, and the inner wall of the flexible body 10 is provided with a limiting boss 14 that matches the limiting groove 211. After the vibration mechanism 20 is installed in the first cavity 11 of the flexible body 10, the limiting boss 14 is engaged in the limiting groove 211. By utilizing the cooperation between 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 ensuring the subsequent training effect.

[0108] It should be noted that in the above terms, "axial" refers to the first direction X, and "radial" 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 component 23 is disposed in the receiving cavity 212. In this embodiment, in order to improve the training effect, the vibration component 23 is preferably two sets, and the two sets of vibration components 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 disposed 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 together limit and fix the flexible button 22, thereby ensuring that the flexible button 22 can block the first opening 12 and that the suction cup 13 can be stably connected to other objects, making it convenient for users to operate and use.

[0111] In some embodiments, the end of the housing 21 near the second opening 213 is provided with a first outward flange 215. The first outward flange 215 is connected to the first step structure 214. The first outward flange 215 can limit the flexible button 22 and prevent the flexible button 22 from moving radially. The first step structure 214 and the suction cup 13 can prevent the flexible button 22 from moving axially.

[0112] In some embodiments, the suction cup 13 is provided with an insert block 131 extending into the first cavity 11 along the first direction X, and a snap-fit ​​groove 15 is formed between the insert block 131 and the inner wall of the flexible body 10; wherein, the first outward flange 215 snaps into the snap-fit ​​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 to other objects, it is necessary to ensure that the flexible button 22 and the suction cup 13 can be interference-fitted to form a semi-closed structure. For this purpose, the flexible button 22 is provided with a second step structure 222, and an interlocking groove 216 is formed between the inner wall of the housing 21 near the second opening 213 and the second step structure 222. The interlocking block 131 cooperates with the interlocking groove 216. Thus, when the first outward flange 215 is engaged with the interlocking groove 15, the interlocking block 131 simultaneously abuts against the interlocking groove 216, thereby forming an interlocking structure. Applying pressure to the training device during training will not cause the flexible button 22 to detach from the suction cup 13, thereby ensuring that a vacuum state is formed inside the suction cup 13 and it is firmly adsorbed onto other objects.

[0114] In some embodiments, to improve the portability of the training device, the vibration mechanism 20 further includes a power supply 24, which is located in the receiving cavity 212. The power supply 24 is configured to supply power to the vibration component 23, thereby improving the portability of the training device. During training, the vibration component 23 can be used to vibrate and massage the muscle tissue, which can effectively relieve sphincter spasms or improve the tension and elasticity recovery of the pelvic floor muscles, thereby improving the training effect.

[0115] In some embodiments, the vibration mechanism 20 further includes a PCB board 25 disposed in the receiving cavity 212. The power supply 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 control the start / stop and frequency of the vibration component 23 when pressed, so that the user can 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, which is electrically connected to the PCB board 25. The charging interface 221 is configured to charge the power supply 24 to improve 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 component 23 includes a motor 231 and an eccentric block 232. The eccentric block 232 is located 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 speed of the motor 231, thereby controlling the vibration frequency of the vibration component 23, so that the user can adjust it according to their own needs to ensure the training effect.

[0120] In some implementations, the motor 231 rotates at a speed of 6000-9000 r / min.

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

[0122] In other embodiments, the vibration component 23 may also be deactivated as needed to achieve a "non-vibration" training mode.

[0123] In some embodiments, the housing 21 is a one-piece structure.

The outer three layers of flexible sleeve are stacked layer by layer to achieve dilation, with a maximum diameter of 3.6cm. The suction cup 13 has a diameter of 5cm.

[0126] In another embodiment, the flexible body 10 has a diameter D1 = 2.5 cm and a length L1 = 8 cm. The motor 231 has a rated voltage of 5V and a rated speed of 8000 r / min. The eccentric block 232 has a mass of 3g and an eccentric distance of 1.5 mm. The first flexible sleeve 31 has a wall thickness H1 = 1.5 mm and a maximum diameter of 2.8 mm. The second flexible sleeve 32 has a wall thickness H2 = 2.5 mm and a maximum diameter of 3.1 mm. The third flexible sleeve 33 has a wall thickness H3 = 3.5 mm and a maximum diameter of 3.4 mm. The first flexible sleeve 31 and the second flexible sleeve 32... The length of the third flexible sleeve 33 in the first direction X is 8.5cm. For pelvic floor rehabilitation training, the initial state is a full sleeve, that is, all three layers of silicone skin are covered on the flexible body 10, with a maximum total diameter of 3.4cm. Then, the layers are removed one by one to carry out the transformation, shrinkage and tightening process. Each time a flexible sleeve is removed, the diameter will decrease by 0.2cm. For anal dilation training, it starts from the smallest flexible body 10 inside, with a diameter of 2.5cm. The outer three layers of flexible sleeve are stacked one by one to achieve dilation, with a maximum diameter of 3.4cm. The diameter of the suction cup 13 is 4cm.

[0127] In another embodiment, the flexible body 10 has a diameter D1 = 4 cm and a length L1 = 12 cm. The motor 231 has a rated voltage of 4.2 V and a rated speed of 7000 r / min. The eccentric block 232 has a mass of 4 g and an eccentric distance of 2.5 mm. The first flexible sleeve 31 has a wall thickness H1 = 2 mm and a maximum diameter of 4.4 mm. The second flexible sleeve 32 has a wall thickness H2 = 3 mm and a maximum diameter of 4.8 mm. The third flexible sleeve 33 has a wall thickness H3 = 4 mm and a maximum diameter of 5.2 mm.

For pelvic floor rehabilitation training, the initial state is a full sleeve, that is, all three layers of silicone skin are covered on the flexible body 10, with a maximum total diameter of 5.2cm. Then, the layers are removed one by one to carry out the transformation, shrinking and tightening process. Each time a flexible sleeve is removed, the diameter will decrease by 0.4cm. For anal dilation training, it starts from the smallest flexible body 10 inside, with a diameter of 4cm.

[0128] In summary, by providing a suction cup 13 at the end of the flexible body 10, the flexible body 10 can be fixed to other objects using the suction cup 13, thereby improving the stability of the training device and making it easier for users to operate and use.

[0129] By incorporating a vibration mechanism 20 within the flexible body 10, the vibration component 23 can be used to massage muscle tissue during training, effectively relieving sphincter spasms or improving the tension and elasticity recovery of the pelvic floor muscles, thereby enhancing training effectiveness. The flexible body 10 has a first opening 12 to facilitate the installation of the vibration mechanism 20. By providing a flexible button 22 at the end of the housing 21, the first opening 12 can be sealed, creating a closed space in the first cavity 11 to protect the vibration mechanism 20. Furthermore, after the flexible button 22 seals the first opening 12, the suction cup 13 can form a semi-closed structure, which is beneficial for the suction cup 13 to be stably fixed on other objects, making it convenient for users to operate and use.

[0130] At least one flexible sleeve 30 is designed to be stacked on the flexible body 10 in a "matryoshka doll" manner, which allows users to flexibly adjust the size of the training device according to actual needs. For example, the size of the training device can be gradually increased by adding flexible sleeves 30, or the size of the training device can be gradually reduced by removing flexible sleeves 30. With the matryoshka doll design, it is no longer necessary to arrange multiple solid structures of different sizes, which can effectively reduce the amount of material used and reduce material costs. Moreover, the matryoshka doll design can reduce the space occupied by the training device, reduce the packaging volume, and make it easier to carry, transport and store.

[0131] In addition, the negative tolerance fit between the flexible sleeve 30 and the flexible body 10 allows for a certain degree of tightness between them, effectively preventing the flexible sleeve 30 from falling off during use and improving ease of use. Furthermore, the multiple flexible sleeves 30 also have a negative tolerance fit, so removing the outermost flexible sleeve does not affect the tightness of the inner flexible sleeve.
