Description
Technical Field
[0001] This application belongs to the field of medical device technology, and more specifically, relates to a hernia belt. Background Technology
[0002] Hernia belts are used to treat hernias. A typical hernia belt consists of a waist belt, leg belts, and a hernia pad attached to the waist belt. One end of the leg belt is fixed to the waist belt near the abdomen, and the other end is fixed to the waist belt near the back of the waist.
[0003] The same hernia belt can be adjusted in different sizes because different people have different body shapes. Since the leg strap is usually fixed to the waist belt, it is difficult to adjust its position, which makes it inconvenient to use. Therefore, it is necessary to produce hernia belts of different sizes to solve this problem. Utility Model Content
[0004] The purpose of this application is to provide a hernia belt to solve the technical problem that the position of the leg strap on the waist belt is difficult to adjust in the prior art.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a hernia belt is provided, comprising: a waist belt; a hernia pad, the hernia pad being disposed on the inner side of the waist belt; and a leg belt, one end of the leg belt being connected to the waist belt, and the other end of the leg belt being provided with a sleeve portion, the sleeve portion having a sleeve hole, the sleeve portion being sleeved on the outside of the waist belt through the sleeve hole, the sleeve portion being movably disposed along the waist belt, and the circumferential dimension of the sleeve hole being smaller than the circumferential dimension of the waist belt.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0036] Hernia belts, commonly used medical devices for treating inguinal hernias, typically consist of three parts: a waist belt, leg straps, and a hernia pad. One end of the leg strap is fixed to the front of the waist belt on the abdomen, and the other end is fixed to the back of the waist belt on the lower back. Due to significant differences in body shape among patients, particularly waist circumference and leg thickness, the leg strap's position needs frequent adjustment. However, most existing hernia belts use a fixed connection method for the leg straps, lacking position adjustment functionality. This not only reduces wearing comfort but also affects treatment effectiveness. To meet the needs of patients with different body types, manufacturers have had to produce hernia belts in various sizes, increasing production costs.
[0037] Please refer to the following: Figures 1 to 5 The hernia belt 100 provided in the embodiments of this application will now be described. The hernia belt 100 includes: a waist belt 10; a hernia pad 40 disposed on the inner side of the waist belt 10; and a leg belt 20, one end of which is connected to the waist belt 10, and the other end of which is provided with a sleeve portion 21. The sleeve portion 21 has a sleeve hole 22. The sleeve portion 21 is sleeved on the outside of the waist belt 10 through the sleeve hole 22. The sleeve portion 21 is movably disposed along the waist belt 10. The circumferential dimension of the sleeve hole 22 is smaller than the circumferential dimension of the waist belt 10.
[0038] The waist belt 10 is the basic component of the entire hernia belt 100, primarily used to secure the entire device to the body. The waist belt 10 is typically worn around the waist, providing support and positioning. The leg straps 20 connect to the waist belt 10, providing auxiliary fixation and working in conjunction with the hernia pad 40 to help push protruding tissue back into place, providing continuous pressure and support to the affected area. The design of the leg straps 20 helps enhance the stability of the entire hernia belt 100, ensuring it is properly positioned on the body and does not easily slip or shift.
[0039] The hernia pad 40 can be directly adhered to the inside of the waist belt 10, or it can be sewn and fixed to the inside of the waist belt 10 using a hernia pouch, or it can be detachably connected to the inside of the waist belt 10 using Velcro. The inside of the waist belt 10 refers to the side of the waist belt 10 that is closest to the human skin after it is worn. In some embodiments, the hernia pad 40 is detachably connected to the inside of the waist belt 10, so the position of the hernia pad 40 can be adjusted according to the length of the waist belt 10 to adapt to different body types. The hernia pad 40 undergoes elastic deformation under pressure, conforming to the contour of the human groin area, and the tension applied by the waist belt 10 concentrates the pressure on the hernia site.
[0040] One end of the leg strap 20 can be fixedly connected to the waist belt 10; alternatively, it can be detachably connected to the waist belt 10 for easy wearing. The other end of the leg strap 20 has a connecting part 21, which is the component at the end of the leg strap 20 used to connect to the waist belt 10. Specifically, the connecting part 21 can be implemented using a ring or semi-ring structure, forming a movable connection with the waist belt 10 through a connecting hole 22. The connecting hole 22 is the opening on the connecting part 21 for the waist belt 10 to pass through. The shape of the connecting hole 22 can be circular, elliptical, or elongated; the size design of the connecting hole 22 must ensure an interference fit with the waist belt 10. The connecting part 21 can be made of elastic fabric or rigid plastic, etc.
[0041] The circumferential dimension of the socket 22 is smaller than that of the belt 10, meaning the inner circumference of the socket 22 is slightly smaller than the outer circumference of the belt 10, to generate friction and prevent the socket 21 from sliding freely on the belt 10. "Modible" means the socket 21 can be adjusted in position on the belt 10, specifically through twisting, rotating, or elastic deformation, to adapt to the needs of users with different body types.
[0042] In some embodiments, the waist belt 10 is made of elastic fabric. In other embodiments, the leg straps 20 are made of soft fabric. One end of the leg strap 20 is connected to the front of the waist belt 10, specifically, it can be a fixed connection (such as sewn) or a detachable connection (such as using Velcro); the other end of the leg strap 20 is provided with a sleeve portion 21, the sleeve portion 21 has an elongated sleeve hole 22, the sleeve portion 21 is fitted onto the outside of the waist belt 10 through the sleeve hole 22, and can slide along the circumference of the waist belt 10. The circumferential dimension of the sleeve hole 22 is slightly smaller than the circumferential dimension of the waist belt 10, so that the sleeve portion 21 fits tightly with the waist belt 10.
[0043] Through the interference fit structure between the sleeve part 21 and the waist belt 10, the end of the leg belt 20 is adjustable and fixed on the waist belt 10. Users can freely adjust the position of the leg belt 20 according to their body shape needs, while avoiding fixation failure due to size mismatch. This solves the problem that the traditional hernia belt 100 cannot flexibly adapt to different body shapes.
[0044] like Figure 2 The streamlined arrow indicates the direction of movement of the leg strap 20. In use, the sleeve part 21 can move along the waist belt 10 to achieve position adjustment. After adjustment, the circumferential dimension of the sleeve hole 22 is smaller than the circumferential dimension of the waist belt 10, so that the sleeve part 21 and the waist belt 10 generate friction to prevent slippage and maintain stable positioning.
[0045] The leg strap 20 is adjustablely connected to the waist belt 10 via the sleeve 21, allowing the hernia belt 100 to adapt to users of different body types. Users can adjust the position of the sleeve 21 to optimize the force on the leg strap 20; the friction caused by the size difference between the sleeve hole 22 and the waist belt 10 ensures that the adjusted position remains stable. This structure achieves position adjustment while avoiding the discomfort introduced by complex mechanical components.
[0046] In use, the user fastens the waist belt 10 around the waist and the leg straps 20 around the upper thighs. The tension of the leg straps 20 is moderate by adjusting the position of the connecting part 21 on the waist belt 10. After adjustment, the friction between the connecting part 21 and the waist belt 10 keeps the position stable. This structure allows the hernia belt 100 to adapt to users of different body types, improving wearing comfort and support.
[0047] Compared with the prior art, the hernia belt 100 provided in this application embodiment has a sleeve part 21 at the end of the leg belt 20. The sleeve part 21 is located on the outside of the waist belt 10 through the sleeve hole 22 and can slide around the waist belt 10. The user can freely adjust the position of the leg belt 20 according to the body shape requirements. The circumferential dimension of the sleeve hole 22 is slightly smaller than the circumferential dimension of the waist belt 10, so that the sleeve part 21 fits tightly with the waist belt 10, generating friction, ensuring that the adjusted position remains stable and preventing slippage.
[0048] Please refer to some embodiments of this application. Figures 3 to 5The inner wall of the socket 22 is provided with an anti-slip component 30.
[0049] By incorporating the anti-slip element 30, a contact surface is formed, allowing it to contact the surface of the belt 10 and increasing the coefficient of friction. The anti-slip element 30 can be an anti-slip sheet made of rubber or silicone, or it can be anti-slip bumps or anti-slip strips. The thickness of the anti-slip element 30 can be set between 0.5mm and 2mm. The surface of the anti-slip element 30 can be provided with raised textures to increase the friction between it and the belt 10. The anti-slip element 30 can cover the entire surface of the inner wall of the socket 22, or it can only cover part of the surface.
[0050] When the sleeve part 21 moves along the waist belt 10 to the target position, the anti-slip member 30 generates contact pressure with the outer surface of the waist belt 10. The anti-slip member 30 forms a surface contact with the waist belt 10 through elastic deformation, and the static friction generated on the contact surface counteracts the longitudinal tension on the leg strap 20. This achieves reliable fixation of the leg strap 20 after position adjustment and avoids accidental displacement of the sleeve part 21 due to human movement.
[0051] The anti-slip element 30 increases the friction between the sleeve 21 and the waist belt 10, improving the stability of the sleeve 21 on the waist belt 10 and preventing the sleeve 21 from sliding along the waist belt 10 during use, thus ensuring the effectiveness of the hernia belt 100. At the same time, the anti-slip element 30 does not affect the adjustment of the sleeve 21; the user can still adjust the position of the sleeve 21 on the waist belt 10 as needed.
[0052] Please refer to some embodiments of this application. Figure 3 The anti-slip component 30 extends circumferentially along the wall surface of the socket 22.
[0053] The anti-slip component 30 adopts a continuous annular structure to cover the complete circumferential surface of the inner wall of the sleeve hole 22, forming a closed anti-slip surface around the waist belt 10. Its inner diameter is smaller than the outer diameter of the waist belt 10. It uses elastic deformation to tightly adhere to the surface of the waist belt 10 to ensure circumferential contact.
[0054] The anti-slip element 30 can be a ring-shaped anti-slip material, such as rubber or plastic with anti-slip texture. The anti-slip element 30 is fixed to the inner wall of the socket 22 and extends along the entire circumference of the socket 22. This design allows the anti-slip element 30 to form a larger contact area with the outer surface of the belt 10, thereby increasing friction. Furthermore, the thickness of the anti-slip element 30 can be adjusted as needed to ensure adequate anti-slip performance.
[0055] The anti-slip component 30 forms a continuous circumferential anti-slip layer on the inner wall of the socket 22. When the waist belt 10 passes through the socket 22, the anti-slip component 30 undergoes radial compression deformation because its inner diameter is smaller than the circumferential dimension of the waist belt 10. The positive pressure generated by the elastic deformation is evenly distributed on the outer surface of the waist belt 10, and the frictional force acts synchronously at all points along the circumference of the socket 22. This structure ensures that the socket 21 can obtain equal frictional resistance at any moving position of the waist belt 10, avoiding anti-slip failure due to pressure concentration at local contact points. When an external force drives the socket 21 to slide along the waist belt 10, the circumferential anti-slip surface generates uniform frictional damping as a whole, and immediately forms a full circumferential fixation after adjustment, preventing accidental displacement caused by unilateral anti-slip failure.
[0056] This design increases the friction between the sleeve 21 and the waist belt 10, making the position of the sleeve 21 on the waist belt 10 more stable. Therefore, during use, the leg strap 20 is less likely to shift accidentally, ensuring the wearing effect of the hernia belt 100. Furthermore, the circumferential extension of the anti-slip component 30 can evenly distribute pressure, preventing localized wear and extending the service life of the hernia belt 100.
[0057] Please refer to some embodiments of this application. Figure 3 and Figure 4 The anti-slip component 30 includes an anti-slip washer 31, which extends circumferentially along the inner wall of the socket 22, and the waist belt 10 passes through the anti-slip washer 31.
[0058] The anti-slip washer 31 adopts a ring structure. The inner diameter of the anti-slip washer 31 is smaller than the circumferential dimension of the waist belt 10. The inner wall of the anti-slip washer 31 is in direct contact with the outer surface of the waist belt 10. By increasing the contact area between the anti-slip washer 31 and the waist belt 10, the friction force is evenly distributed. When the sleeve part 21 moves along the waist belt 10 to the target position, the anti-slip washer 31 is compressed and deformed to generate radial clamping force. A friction pair with surface contact is formed between the outer surface of the waist belt 10 and the inner wall of the anti-slip washer 31. This structure allows the sleeve part 21 to maintain the static friction force between the anti-slip washer 31 and the waist belt 10 through the elastic deformation of the material itself without an additional locking device, preventing the leg belt 20 from being accidentally displaced during human activity.
[0059] The anti-slip pad 31 is made of rubber or silicone, and its thickness can be in the range of 1 to 3 mm.
[0060] The anti-slip washer 31 increases the friction between the inner wall of the socket 22 and the waist belt 10, making the leg strap 20 more stable on the waist belt 10 and less prone to slippage. Simultaneously, because the anti-slip washer 31 extends circumferentially along the inner wall of the socket 22, it evenly distributes friction, preventing wear caused by excessive localized force. Furthermore, the anti-slip washer 31 does not affect the position adjustment of the leg strap 20 on the waist belt 10, ensuring the adjustability of the hernia belt 100.
[0061] Please refer to some embodiments of this application. Figure 5 Anti-slip parts 30 are provided on both sides of the sleeve hole 22 facing the waist belt 10 along the thickness direction.
[0062] Two anti-slip components 30 are respectively connected to the wall surfaces of the sleeve hole 22 on both sides facing the waist belt 10 along the thickness direction. The anti-slip components 30 can be anti-slip sheets, anti-slip strips, or multiple anti-slip protrusions, etc., and have anti-slip properties. By providing anti-slip components 30 on both sides of the sleeve hole 22, the friction between the sleeve part 21 and the waist belt 10 can be increased, further improving the fixing effect of the sleeve part 21.
[0063] When the waist belt 10 is inserted into the connecting hole 22, the two anti-slip parts 30 contact the two surfaces of the waist belt 10 along its thickness direction. As the connecting part 21 moves along the waist belt 10, the anti-slip parts 30 on both sides simultaneously clamp the two contact surfaces of the waist belt 10. When the connecting part 21 moves to the target position, the bidirectional friction generated by the anti-slip parts 30 on both sides prevents the bidirectional displacement of the connecting part 21 caused by human movement, thus ensuring the stable fixation of the end position of the leg strap 20. This increases the contact area between the connecting part 21 and the waist belt 10, improves the friction between them, and further enhances the fixing effect of the connecting part 21. When adjusting the position of the leg strap 20, the connecting part 21 can be stably fixed on the waist belt 10, preventing the connecting part 21 from sliding during use and improving the stability and comfort of the hernia belt 100.
[0064] Please refer to some embodiments of this application. Figure 5 The anti-slip component 30 includes anti-slip pads 32, with two anti-slip pads 32 respectively connected to the wall surfaces of the sleeve hole 22 facing the waist belt 10 along the thickness direction on both sides.
[0065] The anti-slip pad 32 is made of silicone or rubber, and its surface can be processed with a textured surface. Each side wall of the socket 22 can be fixed with the anti-slip pad 32 by adhesive bonding or heat pressing. The positions of the two anti-slip pads 32 correspond to the two surfaces of the waist belt 10 along its thickness direction. The thickness of the anti-slip pad 32 can be set between 0.5mm and 2mm, and its edge extends to the transition area at the opening of the socket 22. The shape of the anti-slip pad 32 can be circular or rectangular, fitting snugly against the inner wall of the socket 22.
[0066] When the leg movement pulls the leg belt 20, the anti-slip pads 32 on both sides of the connecting hole 22 generate frictional resistance synchronously with the upper and lower surfaces of the waist belt 10. The two anti-slip pads 32 form a symmetrical clamping structure, which can balance the frictional torque on both sides when the waist belt 10 is subjected to torsional force, avoiding slippage caused by uneven force on one side of the anti-slip part 30. This structure allows the leg belt 20 to maintain a stable position during complex movements such as bending and turning, without the need for repeated adjustments to the fixing point. The anti-slip pads 32 on both sides increase the friction between the connecting part 21 and the waist belt 10, improving the stability of the connecting part 21 on the waist belt 10. This prevents the connecting part 21 from slipping during use, ensuring the effectiveness of the hernia belt 100.
[0067] Please refer to some embodiments of this application. Figure 4 The socket 22 extends along the width of the socket 21.
[0068] The socket 22 is configured to extend along the width direction of the socket portion 21, which refers to the axis perpendicular to the direction in which the leg strap 20 extends from the waist belt 10. When the socket 22 extends along the width direction of the socket portion 21, the inner wall of the socket 22 forms a continuous contact surface in the width direction, making surface contact with the circumferential surface of the waist belt 10. When adjusting the position of the leg strap 20, the contact area between the circumferential surface of the waist belt 10 and the inner wall of the socket 22 is evenly distributed along the width direction, avoiding localized stress concentration. Through the extension of the socket 22 in the width direction, the sliding resistance of the waist belt 10 within the socket 22 is evenly distributed, ensuring smooth movement adjustment.
[0069] The circumferential dimension of the socket 22 is smaller than that of the waist belt 10, and the socket 22 extends along the width direction of the socket portion 21. The socket 22 can be elongated, with its length direction consistent with the width direction of the socket portion 21. This design allows the socket 22 to better adapt to the width of the waist belt 10, facilitating the sliding adjustment of the socket portion 21 on the waist belt 10.
[0070] Because the socket 22 extends along the width of the socket 21, the socket 21 can be more stably fitted onto the waist belt 10, reducing the possibility of the socket 21 shifting or falling off during use. At the same time, this design also makes it easier for the user to adjust the position of the leg straps 20, improving the applicability and comfort of the hernia belt 100.
[0071] Please refer to some embodiments of this application. Figure 4 The sleeve part 21 includes an elastic collar, the circumferential dimension of the inner wall of the elastic collar being smaller than the circumferential dimension of the waist belt 10.
[0072] The inner circumferential dimension of the elastic collar is smaller than that of the waist belt 10, causing elastic deformation when the elastic collar comes into contact with the waist belt 10. This elastic deformation applies radial pressure to the waist belt 10, thereby increasing the friction between them. The elastic collar is made of an elastic material, such as elastic fabric or rubber. The opening shape of the elastic collar matches the cross-sectional shape of the waist belt 10; for example, when the waist belt 10 is a flat strip, the opening of the elastic collar is also flat.
[0073] When the elastic loop is fitted over the waist belt 10, it contracts radially because its inner circumferential dimension is smaller than that of the waist belt 10, resulting in a tight contact between the inner wall of the elastic loop and the surface of the waist belt 10. At this time, the elastic loop applies a clamping force to the waist belt 10 through the restoring force of the elastic material, thus preventing accidental slippage of the fitting part 21 after it moves to the target position. When the position of the fitting part 21 needs to be adjusted, external force can overcome the friction between the elastic loop and the waist belt 10, allowing the fitting part 21 to move along the waist belt 10. The elastic deformation capability of the elastic loop ensures that it provides sufficient clamping force without causing deformation of the waist belt 10 or affecting wearing comfort due to excessive compression. Therefore, the fitting part 21 can be stably fixed to the waist belt 10 while maintaining positional adjustability, preventing the leg strap 20 from failing to support itself due to accidental slippage.
[0074] The elastic collar can be integrally molded from elastic fabric, forming a closed ring structure. The elastic collar fits onto the outer surface of the waist belt 10 along its length, creating an interference fit. When the user adjusts the position of the leg strap 20, the elastic collar allows the fitting part 21 to move freely through temporary deformation. After adjustment, the elastic collar automatically returns to its initial size, providing a continuous gripping effect on the waist belt 10, preventing unexpected displacement of the leg strap 20 during use, thus adapting to the personalized needs of users with different body types for the position of the leg strap 20.
[0075] In some embodiments of this application, two leg straps 20 are provided, and the two leg straps 20 are respectively provided on both sides of the waist belt 10 along the length direction.
[0076] Two leg straps 20 are symmetrically distributed along the length of the waist belt 10, corresponding to the left and right groin areas of the human body, respectively. The position of each leg strap 20 can be independently adjusted via the movable adjustment function of the connecting part 21. The connection points between the leg straps 20 and the waist belt 10 are located on both sides of the hip area. By adjusting the movement distance of the connecting part 21 on the waist belt 10, the leg straps 20 can adapt to different hip widths.
[0077] The socket 22 extends along the width of the socket 21, allowing the socket 21 to remain in close contact with the waist belt 10 during movement. By adjusting the positions of the leg straps 20 on both sides, it can accommodate the needs of users with different body types, eliminating the need to produce multi-size products. Since the two leg straps 20 are respectively arranged on both sides of the waist belt 10, the position of the socket 21 on the waist belt 10 can be independently adjusted according to individual waist circumference differences during wear, avoiding uneven force caused by unilateral adjustment. This structure allows the socket position of the leg strap 20 on the waist belt 10 to adapt to the waist curve of users with different body types, effectively reducing the problem of insufficient product adaptability caused by a single fixed position of the leg strap 20.
[0078] Please refer to some embodiments of this application. Figures 6 to 13 The waist belt 10 has a first connecting portion 61 on its inner side along the thickness direction, and the first connecting portion 61 extends along the length direction of the waist belt 10. The hernia belt 100 also includes a hernia bag clamping member 50, which includes a clamping member 52. The clamping member 52 has a first clamping portion 521 and a second clamping portion 522 disposed opposite to each other. The side of the first clamping portion 521 near the second clamping portion 522 is provided with a clamping surface 5211, and the side of the second clamping portion 522 away from the first clamping portion 521 is provided with a connecting surface 5221. The clamping surface 5211 is provided with a second connecting portion 70, which is detachably connected to the first connecting portion 61. The hernia pad 40 is provided on the side of the first clamping portion 521 away from the clamping surface 5211. The connecting surface 5221 is located on the outer side of the waist belt 10, and the connecting surface 5221 is provided with a third connecting portion (not shown in the figure) for connecting the leg strap 20.
[0079] The hernia belt 100 includes a waist belt 10 and a hernia pad clamp 50. The waist belt 10 is the basic component of the entire hernia belt 100 and is mainly used to secure the entire device to the human body. The waist belt 10 is usually worn around the waist to provide the necessary support and positioning for the hernia pad 40.
[0080] like Figure 8The clamping member 52 has a first clamping part 521 and a second clamping part 522. One end of the first clamping part 521 is connected to one end of the second clamping part 522. The first clamping part 521 is provided with a clamping surface 5211. The waist belt 10 is provided with a first connecting part 61 on the inner side along the thickness direction. The inner side of the waist belt 10 along the thickness direction refers to the side of the waist belt 10 that is close to the human skin after being worn. Since the first connecting part 61 extends along the length direction of the waist belt 10, the second connecting part 70 is detachably connected to the first connecting part 61. Therefore, the second connecting part 70 can move along the length direction of the waist belt 10 on the first connecting part 61 and be fixed at any position on the first connecting part 61. The hernia pad 40 is located on the side of the first clamping part 521 away from the clamping surface 5211, that is, the hernia pad 40 is located on the side closer to the human skin. Therefore, the user can freely adjust the position of the hernia pad 40 according to the specific location of their condition (such as left groin, right groin or umbilical hernia, etc.), so as to achieve flexible adjustment of the position of the hernia pad 40 to adapt to different body types and lesion locations.
[0081] In traditional designs, due to the fixed position or limited adjustment range of the hernia pad 40, different models of hernia belts 100 must be produced for people of different body types. This application, through a detachable connection structure, with the first connecting part 61 extending along the length of the waist belt 10, allows the same product to fit multiple body types, reducing the number of models. Only one specification of hernia belt 100 needs to be produced to accommodate different users' body shapes, thus reducing development costs.
[0082] The clamping element 52 can be made of nylon or polyester fiber, or it can be a flexible board made of polyvinyl chloride, etc.
[0083] The mating structure between the first connecting part 61 and the second connecting part 70 can specifically be a Velcro mating structure. For example, a textured surface (first connecting part 61) can be provided on the belt 10, and a hook surface (second connecting part 70) can be provided on the clamping member 52, realizing a detachable connection between the two, which is simple and easy to use. In some embodiments, the belt 10 itself has a textured surface, in which case the textured surface of the belt 10 itself can be directly used as the first connecting part 61, reducing unnecessary material stacking.
[0084] The specific cooperation structure between the first connecting part 61 and the second connecting part 70 can also be a slide rail and a buckle. For example, a buckle (second connecting part 70) is provided on the clamping member 52, and multiple slide rails (first connecting part 61) are provided on the belt 10 along the length direction. The clamping member 52 can slide up and down along the slide rails through the buckle and be locked in the desired position.
[0085] The mating structure between the first connecting part 61 and the second connecting part 70 can also be a snap fastener structure or a female-female buckle structure, such as having multiple female buckles along the length of the belt 10 and corresponding female buckles on the clamping member 52. Furthermore, the mating structure between the first connecting part 61 and the second connecting part 70 can also be a magnetic mating structure, or a hook and loop belt mating structure, etc.
[0086] like Figure 12 and Figure 13 Users can adjust the hernia pad 40 to the most suitable pressure position according to actual needs, improving wearing comfort and treatment effect. The clamping part 52 is easy to disassemble and install, easy to clean or replace, and easy to adjust according to changes in the condition.
[0087] The first connecting part 61 can extend along the entire length of the waist belt 10, and the first connecting part 61 and the second connecting part 70 are detachably connected, allowing the hernia pad clamp 50 to move freely and be fixed along the entire length of the waist belt 10, breaking the limitations of traditional hernia pad 40 fixation. The clamp 52 is not only used to fix the hernia pad 40, but also serves as a functional module connected to the waist belt 10, realizing the separation of structure and function.
[0088] A connecting surface 5221 is provided on the side of the second clamping part 522 opposite to the first clamping part 521, and the connecting surface 5221 is located on the outside of the waist belt 10. A third connecting part is provided on the connecting surface 5221 for connecting with the leg strap 20. When the user needs to use the leg strap 20, one end of the leg strap 20 can be connected to the connecting surface 5221 of the clamping member 52 through the third connecting part, and the other end can be sleeved on the outside of the waist belt 10 through the sleeve part 21, forming an oblique tension structure from the waist to the leg. This helps to prevent the hernia bag clamping member 50 from sliding up and down or rotating during use due to body movement. It not only relies on the fixing effect of the waist belt 10 itself, but also adds extra support from the leg, ensuring that the hernia pad 40 is always in the correct position. This enhances overall stability and prevents the hernia bag clamping member 50 from shifting. For patients who need to stand, walk, or even engage in light exercise, the extra support provided by the leg strap 20 helps them maintain the stability of the hernia belt 100 during daily activities. The leg strap 20 can also transfer some of the pressure from the waist to the groin, reducing the pressure concentration in the waist and avoiding localized pressure caused by prolonged wear; through the joint support of the waist and legs, the pressure distribution of the entire device is more even, improving the comfort of wearing it.
[0089] The hernia belt 100 provided in this embodiment, compared with the prior art, has a first connecting portion 61 provided on the inner side of the waist belt 10, and the first connecting portion 61 extends along the length direction of the waist belt 10. The clamping member 52 has a first clamping portion 521 and a second clamping portion 522 disposed opposite to each other. A clamping surface 5211 is provided on the first clamping portion 521, and a connecting surface 5221 is provided on the side of the second clamping portion 522 opposite to the first clamping portion 521. The connecting surface 5221 is provided with a third connecting portion for connecting the leg strap 20, which facilitates the installation of the leg strap 20. A second connecting portion is provided on the clamping surface 5211. The second connecting part 70 is detachably connected to the first connecting part 61. The second connecting part 70 can move along the length of the waist belt 10 and be fixed at any position of the first connecting part 61. This method allows the hernia pad clamp 50 to move freely and be fixed within the entire length of the waist belt 10. The hernia pad 40 is located on the first clamping part 521. Users can freely adjust the position of the clamp 52 according to the specific location of their condition, so as to achieve flexible adjustment of the position of the hernia pad 40, adapting to different body types and lesion locations. Moreover, this design can enable the same product to adapt to multiple body types, reducing the number of models.
[0090] One end of the leg strap 20 can be detachably connected to the second clamping part 522 via the third connecting part, making it convenient for users to wear and allowing for quick assembly and disassembly of the leg strap 20 as needed. The leg strap 20 transfers some pressure from the waist to the groin, reducing the burden on the waist, avoiding localized pressure caused by prolonged wear, and improving overall comfort and fit.
[0091] The third connecting part can be a connecting buckle, and the leg strap 20 can be directly inserted into the connecting buckle and connected to the second clamping part 522; the third connecting part can also be a hook and loop fastener, and the end of the leg strap 20 forms a rough surface, which can be directly pasted onto the hook and loop fastener.
[0092] The leg strap 20 provides additional support to prevent the hernia pad clamp 50 from shifting or falling off during use due to body movement. Through dual fixation of the legs and waist, it ensures that the hernia pad 40 is always in the correct position, thereby improving the treatment effect.
[0093] Please refer to some embodiments of this application. Figure 6 and Figure 10 The waist belt 10 has a first connecting part 61 on both sides along the thickness direction. The second clamping part 522 has a clamping surface 5211 on the side near the first clamping part 521. The clamping member 52 is clamped to both sides of the waist belt 10 through the two clamping surfaces 5211.
[0094] like Figure 8A clamping surface 5211 is provided on the side of the second clamping part 522 near the first clamping part 521, so that the clamping member 52 has two opposing clamping surfaces 5211. The clamping member 52 is connected to the waist belt 10 by clamping. Each of the two clamping surfaces 5211 is provided with a second connecting part 70, and the two second connecting parts 70 are detachably connected to the two first connecting parts 61 on the waist belt 10. By cooperating with the two clamping surfaces 5211 of the clamping member 52, a clamping and fixing method is formed on both sides of the waist belt 10, which can more firmly fix the hernia bag clamping member 50 to the waist belt 10, making it less likely to shake or misalign, and preventing it from shifting or falling off during use.
[0095] The hernia clamp 50 is clamped and fixed to the waist belt 10, and is not easy to loosen during exercise or daily activities, reducing discomfort caused by changes in pressure points.
[0096] Please refer to some embodiments of this application. Figure 6 and Figure 10 At least one clamping surface 5211 of the clamping member 52 extends along the width direction of the waist belt 10 and protrudes from one side of the waist belt 10, and the protrusion of the clamping surface 5211 protruding from the waist belt 10 is detachably connected to another clamping surface 5211.
[0097] At least one clamping surface 5211 of the clamping member 52 extends from one side of the waist belt 10 along the width direction of the waist belt 10, forming a protrusion. This protrusion of the clamping surface 5211 can be connected to another clamping surface 5211 around the waist belt 10, forming a ring-shaped surrounding connection structure. This allows the hernia bladder clamping member 50 to be securely connected to the waist belt 10, effectively preventing rotation of the hernia bladder clamping member 50 during use or back-and-forth swaying or misalignment caused by body movement. For patients who need to walk, stand, bend over, or even engage in light exercise, this structure ensures that the hernia pad 40 is always in the correct pressure position, reducing the risk of treatment failure due to device detachment.
[0098] The protrusion of the clamping surface 5211 can also be connected in a detachable manner, such as the combination of the hook and loop side of the Velcro. Users can easily and quickly disassemble the entire hernia clamp 50. The disassembly and assembly process is simple and intuitive and does not require tools.
[0099] Furthermore, if a leg strap 20 is provided, it may exert an outward or downward pulling force on the hernia bladder clamp 50 when worn. When the clamp 52 forms a ring-shaped surrounding connection structure, it can effectively resist this pulling force and prevent the hernia bladder clamp 50 from shifting or falling off. Even if the leg strap 20 pulls on the clamp 52 due to movement, the entire hernia bladder clamp 50 can still maintain a fixed position due to the locking effect between the second connecting part 70 and the third connecting part.
[0100] Please refer to some embodiments of this application. Figure 11 The two clamping surfaces 5211 of the clamping member 52 extend along the width direction of the belt 10 and protrude from one side of the belt 10. A second connecting portion 70 on one clamping surface 5211 extends to the protrusion, and a fourth connecting portion (not shown) is provided on the protrusion of the other clamping surface 5211. The second connecting portion 70 and the fourth connecting portion are detachably connected.
[0101] The two clamping surfaces 5211 of the clamping member 52 extend from one side of the waist belt 10 along the width direction of the waist belt 10 to form protrusions. The two protrusions are connected at the outer position of the waist belt 10 to effectively prevent the hernia bag clamping member 50 from moving or misaligning during use.
[0102] like Figure 8 and Figure 11 The second connecting part 70 covers one of the clamping surfaces 5211, and a fourth connecting part is provided on the protrusion of the other clamping surface 5211. By providing the fourth connecting part to connect with the second connecting part 70, the two protrusions of the clamping member 52 are fixed, so that the hernia bag clamping member 50 can be more securely connected to the waist belt 10.
[0103] The mating structure between the fourth connecting part and the second connecting part 70 can be a hook and loop fastener structure, a snap fastener structure, a snap-on structure, or a magnetic structure, etc. In some embodiments, the second connecting part 70 is a hook and loop fastener and the fourth connecting part is a loop fastener, so that the fourth connecting part and the second connecting part 70 can be detachably connected, which is simple in structure and convenient in connection.
[0104] By detachably connecting the fourth connecting part to the second connecting part 70, the clamping member 52 is not only fixed to the waist belt 10 by clamping, but also forms an additional mechanical connection point on the outside, which greatly improves the anti-slip and anti-dislodgement ability of the entire hernia sac clamping member 50. Even if the patient is frequently active, it can ensure that the hernia pad 40 is always in the correct position.
[0105] Please refer to some embodiments of this application. Figure 6 There are two clamping members 52, which are spaced apart on the waist belt 10.
[0106] Many patients may suffer from bilateral inguinal hernias (with hernias protruding on both sides). By setting two clamps 52, bilateral synchronous pressure can be applied on the same waist belt 10, supporting the treatment of bilateral hernias, meeting a wider range of clinical application scenarios, and improving applicability.
[0107] With two clamping components 52, when the hernia pad 40 is designed to be replaceable, it can be used unilaterally or bilaterally as needed. One or two hernia pads 40 can be installed depending on the condition, eliminating the need for different models designed for different patients, thus improving product versatility and adaptability to a wider range of people. Each clamping component 52 exists independently; if one is damaged or needs replacement, the entire device does not need to be replaced. The position of each clamping component 52 can be adjusted individually, allowing for precise positioning based on the specific location and size of the hernia on different sides and the patient's body type, achieving more accurate pressure control and improving treatment outcomes.
[0108] In some embodiments of this application, the first connecting portion 61 is one of the hook and loop side and the hook and loop side, and the second connecting portion 70 is the other of the hook and loop side and the hook and loop side.
[0109] If the first connecting part 61 has a rough surface, then the second connecting part 70 has a hook surface, and vice versa. The use of Velcro allows for detachable connections, resulting in a simple structure, low cost, and ease of manufacturing. Velcro is a mature and widely used connecting material with low production costs and mature technology. Velcro allows for fixation at any position within a certain range, enabling users to flexibly adjust the position of the hernia pad 40 according to their condition, improving wearing comfort and treatment effectiveness.
[0110] When the first connecting part 61 is located on the waist belt 10 and the second connecting part 70 is located on the clamping member 52, a symmetrical force-bearing structure can be formed by the double-sided Velcro connection, preventing the hernia patella clamping member 50 from shifting or falling off. It is suitable for patients who need to wear it for a long time or who are frequently active.
[0111] The Velcro connection method makes it easy to operate; simply stick or peel to complete the installation or removal without the need for tools. It also facilitates the replacement of the hernia pad 40, cleaning of components, or adjustment of position according to changes in the condition.
[0112] In some embodiments of this application, the hernia pack clamping member 50 further includes a receiving member 51. The receiving member 51 is connected to the side of the first clamping part 521 that is away from the clamping surface 5211 and is located inside the waist belt 10. The receiving member 51 and the clamping member 52 enclose and form a receiving space 511, and the hernia pad 40 is disposed in the receiving space 511.
[0113] like Figure 7 and Figure 9 The receiving member 51 is connected to the side of the first clamping part 521 opposite to the waist belt 10 and is located inside the waist belt 10. Therefore, after the receiving member 51 and the clamping member 52 form a receiving space 511, the hernia pad 40 can be placed in the receiving space 511 and located inside the waist belt 10. With the help of the external force provided by the waist belt 10, the hernia pad 40 pushes the protruding hernia bulge back to its original position; at the same time, it maintains appropriate pressure to prevent the hernia from protruding again, thereby relieving the patient's symptoms.
[0114] The receiving component 51 serves as the carrier of the hernia pad 40. When the position of the hernia pad 40 needs to be adjusted, the position of the clamping component 52 can be adjusted accordingly. That is, the entire hernia pad clamping component 50 moves along the length of the waist belt 10 and is fixed in an appropriate position to meet the needs of different patients.
[0115] The receiving member 51 can be integrally formed with a clamping surface 5211 of the clamping member 52. The material of the receiving member 51 can be nylon, polyester fiber, or spandex, etc. The hernia pad 40 can be fixed in the receiving space 511, or an opening can be provided in the receiving space 511 to remove and replace the hernia pad 40.
[0116] Please refer to some embodiments of this application. Figures 9 to 11 One end of the receiving member 51 is provided with a placement opening 512, which is connected to the receiving space 511.
[0117] The receiving member 51 and the clamping member 52 enclose a receiving space 511, which can be a closed structure. The hernia pad 40 is pre-installed in the receiving space 511 and cannot be removed after installation. Alternatively, a placement port 512 can be provided on the receiving member 51, through which the hernia pad 40 can be placed or removed, facilitating the replacement of different hernia pads 40. Users can change to hernia pads 40 of different shapes, hardness, and sizes according to their own condition (such as inguinal hernia, umbilical hernia, etc.) or treatment stage to meet personalized medical needs and improve treatment effectiveness.
[0118] Hernia pad 40 may accumulate sweat or breed bacteria during long-term use. The removable design allows users to periodically remove the hernia pad 40 for cleaning or disinfection, maintaining hygiene and extending its service life.
[0119] When the hernia pad 40 needs to be replaced due to wear, aging or damage, only the internal hernia pad 40 needs to be replaced, reducing usage costs and improving product cost-effectiveness.
[0120] Please refer to some embodiments of this application. Figure 6 and Figure 10 The hernia belt 100 includes a connector 60, which is sleeved on the waist belt 10 and extends along the length of the waist belt 10. The connector 60 is fixedly connected to the waist belt 10, and each first connecting part 61 is provided on the connector 60.
[0121] The entire connector 60 is an independent functional component, integrating two connection points (i.e. two first connection parts 61) to provide a standard connection structure for the hernia bag clamp 50. The first connection parts 61 are provided on both sides of the connector 60, so that the hernia bag clamp 50 can be connected to the two first connection parts 61 respectively by clamping. The double-sided connection is more stable and prevents displacement and detachment.
[0122] The connector 60 is fitted onto the waist belt 10 and is fixedly connected to it. The connector 60 is a ring-shaped wrap, with two first connecting parts 61 on its left and right sides, such as Velcro, magnetic modules, or buckles. The connector 60 can be pre-fixed as a whole structure in the most suitable treatment area, making connection convenient. The user only needs to clamp the hernia pack holder 50 on both sides of the connector 60 to quickly complete the installation. The operation is simple and intuitive. Furthermore, the connector 60 extends along the length of the waist belt 10, allowing the position of the hernia pack holder 50 to be flexibly adjusted.
[0123] Please refer to some embodiments of this application. Figures 8 to 10 The hernia clamp 50 also includes an intermediate connector 53, which is located between the two clamping surfaces 5211 of the clamp 52.
[0124] By setting an intermediate connector 53 between the two clamping surfaces 5211, a gap is created between the two clamping surfaces 5211. The belt 10 usually has a certain thickness. If the gap between the two clamping surfaces 5211 of the clamping member 52 is small or is a rigid structure, it may not fit completely. Setting the intermediate connector 53 to have a certain thickness can fill the gap in the clamping space, making it easier for the clamping member 52 to fit the surface of the belt 10, resulting in a tighter and more stable clamping.
[0125] The intermediate connector 53 can be made of a soft material (such as fabric or rubber), which has good flexibility and smoothness, making the wearing process more natural and comfortable. The intermediate connector 53 can be integrated with the clamping member 52 as one part of the clamping member 52.
[0126] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
