Description

Technical Field

[0001] This disclosure relates to the field of medical device technology, and in particular to a circumcision bag retainer assembly and circumcision bag device. Background Technology

[0002] An ostomy bag is an important medical device primarily used in healthcare and surgical care. It is attached to the patient's abdomen and drains waste through a stoma, making it suitable for patients with bowel or bladder diseases and those with impaired excretory function. The ostomy bag not only protects the skin from irritation caused by excrement but also significantly improves the patient's quality of life.

[0003] Based on the design principle of ostomy bags, the connecting rings are typically installed and removed by pushing or pulling them towards the patient. This design makes the use of ostomy bags simpler and more user-friendly, as patients or caregivers can easily connect or disconnect the ostomy bag from the stoma baseplate by simply pushing or pulling the rings. This method improves the convenience and efficiency of the procedure. In this way, the process of removing and installing ostomy bags becomes simpler and faster, allowing patients to more easily manage their stoma care needs in daily life.

[0004] However, the ostomy bag connection methods in these technologies have certain problems, especially during the installation and removal process, which may cause secondary injury to the patient. This secondary injury not only exacerbates their discomfort but may also increase their suffering. Summary of the Invention

[0005] This disclosure provides a clamping ring assembly and an ostomy bag device for an ostomy bag, which can be disassembled and assembled from the side via a clamping structure, making it less likely to cause secondary injury to the patient, improving patient comfort, reducing patient pain, and improving the sealing performance of the ostomy bag after installation by utilizing multi-layer sealing.

[0006] In a first aspect, this disclosure provides a retaining ring assembly for an ostomy bag, the retaining ring assembly including a first annular body, a second annular body, and a clamping structure.

[0007] The first annular body has a first communication port. The first annular body includes a sealing part and a first snap-fit ​​part connected to each other. The sealing part is sealed to the ostomy bag, and the first snap-fit ​​part is located on the side of the sealing part away from the ostomy bag.

[0008] The second annular body has a second communication port. The second annular body includes a connecting fitting part and a second snap-fit ​​part. The fitting part can be fitted to a preset position, and the first snap-fit ​​part is adapted to the second snap-fit ​​part.

[0009] The clamp structure is movably connected to the first annular body or the second annular body. The clamp structure has a groove, and the two groove walls can respectively press the first and second locking parts after docking, so that the clamp structure locks the first and second annular bodies.

[0010] The first and second locking parts are provided with at least two sets of annular contact surfaces in their mating areas, and at least two sealing structures are formed between the first and second locking parts in the locked state.

[0011] In the above structure, the retaining ring assembly of the ostomy bag disclosed herein can be disassembled and assembled from the side via the retaining structure, which is less likely to cause secondary injury to the patient, improves the patient's comfort, and reduces the patient's pain.

[0012] The ostomy bag retainer assembly in the above structure consists of a first annular body, a second annular body, and a clamp structure. Through the cooperation of each component, safety and reliability can be ensured during use.

[0013] Specifically, the first annular body has a first connecting port that communicates with the ostomy bag. The first annular body includes a sealing part and a first snap-fit ​​part. The sealing part is sealed to the ostomy bag and forms a whole, effectively preventing leakage of the ostomy bag in the sealing area of ​​the sealing part. The first snap-fit ​​part is located on the side of the sealing part away from the ostomy bag and is used to connect with the second annular body.

[0014] The second annular body has a second connecting port. After the first and second annular bodies are connected, the second connecting port communicates with the first connecting hole. The second annular body includes an adhesive part and a snap-fit ​​part. The adhesive part can be fitted to a preset position to ensure stable installation of the ostomy bag. The preset position can be the patient's skin position. The adhesive part can be fitted by adhesive bonding, specifically by applying double-sided adhesive to the side of the adhesive part near the adhesive position, or by applying single-sided adhesive to the periphery of the adhesive part. The second snap-fit ​​part is adapted to the first snap-fit ​​part. When the second snap-fit ​​part and the first snap-fit ​​part are engaged, they can be pressed, sealed, and locked by a clamp structure.

[0015] The clamp structure is a component that connects two annular bodies. When the first and second clamping parts are aligned, the clamp structure can lock the first and second clamping parts through the clamping groove, thereby achieving relative locking of the first and second annular bodies.

[0016] The clamp structure can exist independently, and the corresponding model of clamp structure is taken out when locking is required. Alternatively, the clamp structure can be movably connected to the first annular body or the second annular body. This disclosure exemplarily describes an embodiment in which the clamp structure is movably connected to the second annular body via a hinged post.

[0017] During the locking process of the clamp structure, the two groove walls on the clamp structure can respectively press against the first and second locking parts after they are joined, thereby achieving the locking function. This side-pressing locking method makes it less likely to generate forces close to or away from the patient's wound during locking or unlocking, greatly reducing the risk of secondary injury to the patient during disassembly and assembly.

[0018] Compared with existing ostomy bag connection methods, the retaining ring assembly of this disclosure has significantly improved the ease of assembly and disassembly and the sealing performance. It not only effectively avoids secondary damage, but also has better sealing performance, ensuring the stability and reliability of the ostomy bag, and providing patients with a more comfortable and safer user experience.

[0019] In some examples, the two groove walls of the slot are offset inward so that during the locking process of the clamp structure, the two groove walls of the slot can apply the force of the first and second clamping parts after they are squeezed together.

[0020] The aforementioned inward offset of the two groove walls allows the clamping structure to generate greater clamping and frictional forces when locking the first and second annular bodies, thus ensuring the stability of the clamping ring assembly. Even when subjected to significant external forces during use, the clamping ring assembly is less prone to loosening or detachment, providing more reliable protection for the patient.

[0021] And / or, in the first and second locking parts after docking, the two pressure surfaces of the first and second locking parts that are opposite to each other are inclined surfaces that are inclined in opposite directions to the outer periphery, so that during the locking process of the clamp structure, the two groove walls of the groove can apply a force to squeeze the first and second locking parts after docking.

[0022] The aforementioned inclined surface design allows the clamp structure to apply compressive force more effectively during the locking process, thereby enhancing the connection strength between the first and second locking parts. Simultaneously, the inclined surface also helps guide the clamp structure's slots to smoothly align with the first and second locking parts, making the assembly and disassembly process smoother and further improving operational convenience.

[0023] In some examples, the first latching portion has at least one annular first protrusion and at least one first groove alternately arranged on the side of the second latching portion near the second latching portion. The second latching portion has at least one annular second protrusion and at least one second groove alternately arranged on the side of the first latching portion near the first latching portion.

[0024] When the first snap-fit ​​portion and the second snap-fit ​​portion are mated, a portion of the first protrusion abuts against the second groove and forms at least two sets of annular contact surfaces, or a portion of the second protrusion fills the first groove and forms at least two sets of annular contact surfaces, so as to form at least two layers of sealing structure.

[0025] The aforementioned multi-layered sealing structure significantly enhances the sealing performance of the ostomy bag retainer assembly, effectively preventing leakage. The alternating protrusions and grooves on the first and second retaining parts ensure a tight fit after connection, maintaining a good seal even under pressure changes or movement. Furthermore, the annular contact surface not only increases the sealing area but also improves the uniformity and stability of the seal, making the ostomy bag safer and more reliable during use. Therefore, this ostomy bag retainer assembly represents an innovation and improvement in sealing performance, providing users with a superior user experience.

[0026] In some examples, the first latching portion has a first protrusion. The second latching portion has a second groove.

[0027] The first protrusion abuts against the second groove, with its top contacting the bottom of the second groove to form a first sealing structure. The two sides of the first protrusion abut against the two groove walls of the second groove, forming a second sealing structure and a third sealing structure, respectively.

[0028] The aforementioned structure creates a multi-layered, multi-dimensional sealing system, further enhancing the reliability and durability of the ostomy bag retainer assembly. The fit between the first protrusion and the second groove not only ensures a tight seal but also reduces wear and loosening that may occur due to prolonged use or improper operation. The direct contact between the top of the first protrusion and the bottom of the second groove forms the first sealing structure, effectively preventing leakage. The tight fit between the two sides of the first protrusion and the walls of the second groove forms additional second and third sealing structures, providing multiple layers of protection for the use of the ostomy bag. This multi-layered sealing structure elevates the performance of the ostomy bag retainer assembly to a new level, meeting users' urgent needs for high-quality, high-reliability ostomy bags.

[0029] In some examples, the first latching portion has a first groove and two first protrusions on both sides of the first groove. The second latching portion has a second groove and two second protrusions on both sides of the second groove.

[0030] The top of one of the first protrusions abuts against the bottom of the second groove, forming a first sealing structure. The two sides of the first protrusion abut against two second protrusions respectively, forming a second sealing structure and a third sealing structure.

[0031] The top of the second protrusion, which abuts against the first groove, can abut against the bottom of the first groove, forming a fourth sealing structure. Alternatively, the side of the second protrusion can abut against another first protrusion, forming a fifth sealing structure.

[0032] The aforementioned structure features a more complex snap-fit ​​and sealing mechanism, enhancing not only the structural stability of the ostomy bag retainer assembly but also further improving sealing performance. The first groove on the first snap-fit ​​portion and the first protrusions on both sides cooperate with the second groove on the second snap-fit ​​portion and the second protrusions on both sides to form a multi-layered, multi-dimensional sealing network. Direct contact between one of the first protrusions and the bottom of the second groove constitutes the first sealing structure, effectively preventing leakage. Simultaneously, this first protrusion fits tightly with the second protrusions on both sides, forming the second and third sealing structures respectively, providing additional protection for the use of the ostomy bag.

[0033] The second protrusion, which abuts against the first groove, has its top tightly fitted to the bottom of the first groove, forming a fourth sealing structure that further enhances the sealing effect. Alternatively, the side of the second protrusion can make close contact with another first protrusion, forming a fifth sealing structure. This arrangement provides more flexible sealing options in specific situations to meet the needs of different users.

[0034] In some examples, the first protrusion and / or the second protrusion are flexible structures. During the mutual compression of the first and second snap-fit ​​portions, the first and / or the second protrusions elastically deform and form a multi-layer sealing structure.

[0035] This flexible structure allows the protrusions to adaptively adjust to the shape and pressure distribution of the locking parts during the engagement process. When the first and second locking parts are pressed against each other, the flexible protrusions undergo elastic deformation, thus fitting more tightly between the groove and adjacent protrusions, forming a denser and more stable sealing layer.

[0036] In some examples, the locking area of ​​the clamp structure is provided with a quick-release mechanism. And / or, quick-lock protrusions are provided on both sides of the locking area of ​​the clamp structure.

[0037] The aforementioned quick-release structure and / or quick-lock protrusion provide users with significant convenience when using the ostomy bag's retainer assembly. The quick-release structure allows users to quickly and easily release the retainer when needed, without complicated operations or tools, greatly saving time and effort. Simultaneously, the quick-lock protrusion ensures the stability and security of the retainer structure in the locked state, preventing unlocking due to accidental contact or slight vibration. This design not only improves the ease of use of the retainer assembly but also enhances its reliability and durability in practical applications, providing users with a more convenient and efficient user experience.

[0038] In some examples, hinged posts are provided on the first annular body and / or the second annular body, and the clamp structure is hinged to the hinged posts.

[0039] This hinged design allows the clamp structure to move and lock flexibly between the first and second annular bodies, further enhancing the adjustability and adaptability of the ostomy bag device. Users can easily lock and unlock the clamp structure according to their actual needs, improving the efficiency of ostomy bag replacement.

[0040] Alternatively, the clamp structure can be set independently, and when the first annular body and the second annular body are engaged, the clamp structure locks the first and second engaging parts after they are connected.

[0041] At this point, the clamp structure exists as an independent component, not relying on any part of the first or second annular body for fixation or connection. When the first and second annular bodies need to be engaged, the user can place the clamp structure between the engaged first and second engagement parts, and achieve quick and stable locking through the quick-release mechanism and quick-locking protrusion. This independently designed clamp structure provides greater flexibility and adaptability, allowing the clamp ring assembly to be applied to a wider range of ostomy bag devices and designs. Simultaneously, the independently designed clamp structure facilitates user replacement or maintenance, further improving the ease of use and practicality of the ostomy bag device.

[0042] In some examples, the clamp structure is a double-locking structure. The clamp structure is assembled and disassembled through a combination of double protrusions and double slots. During the locking process, the size of the wedge-shaped protrusion that engages first is larger than the size of the wedge-shaped protrusion that engages later. The double slots are also corresponding wedge-shaped slots. This double-locking structure ensures that even if one set of wedge-shaped protrusions and slots disengages due to accidental contact or loosening, the other set of wedge-shaped protrusions and slots will still maintain the clamp's lock, further reducing the possibility of the clamp structure unlocking due to accidental contact, ensuring stable locking of the clamp structure, and thus improving the stability of the retaining ring structure.

[0043] In some examples, pull ring structures are provided on both sides of the second ring-shaped body, and the two pull ring structures can work with elastic ropes to bind the second ring-shaped body to the human torso.

[0044] The aforementioned pull-loop structure not only facilitates the user's attachment of the ostomy bag to the body, but also, through the elasticity of the cord, adapts to patients of different body types, ensuring the stability and comfort of the device. The pull-loop design is simple and easy to use; users simply thread the elastic cord through the pull-loop and adjust the tightness appropriately to achieve a secure fixation. Furthermore, the pull-loop structure allows for easy replacement or adjustment of the ostomy bag, greatly improving convenience and efficiency.

[0045] In some examples, the clamp structure is a split clamp, which includes a first clamp and a second clamp. The first end of the first clamp and the first end of the second clamp are both hinged to the hinge post. In the locked state, the second end of the first clamp and the second end of the second clamp are detachably connected.

[0046] The split-type clamp structure consists of two main parts: a first clamp and a second clamp. Specifically, one end of both the first and second clamps is hinged to the same hinge post. When the clamp structure is locked, the other ends of the first and second clamps can be detachably connected. This design provides flexibility and convenience during use, while also ensuring stability and reliability in the locked state.

[0047] Alternatively, the clamp structure is an integral clamp, with the first end of the clamp structure hinged to the hinge post, and the second end of the clamp structure detachably connected to the first end of the clamp structure after wrapping around the first annular body and / or the second annular body at least once.

[0048] In the aforementioned structure, the clamp structure is designed as a single, integral clamp. The first end of this clamp structure is hinged to a hinged post. The second end of the clamp structure encircles the first and / or second annular bodies at least once, allowing for a detachable connection at the first end. This design provides the clamp structure with flexibility and adjustability during use, while also facilitating installation and disassembly. This structure effectively secures and stabilizes the first and second annular bodies, ensuring the stability and reliability of the entire device.

[0049] Secondly, this disclosure also provides an ostomy bag device, including the above-mentioned ostomy bag retaining ring assembly and the ostomy bag, wherein the ostomy bag and the retaining ring assembly are sealed together.

[0050] The aforementioned ostomy bag device includes a retaining ring assembly for the ostomy bag as described above, and an ostomy bag. Specifically, the ostomy bag device tightly connects the ostomy bag and the retaining ring assembly through a sealing connection. This design not only ensures the stability and sealing of the ostomy bag but also facilitates user use and replacement, thereby improving overall comfort and practicality. Through this structure, the ostomy bag device can effectively collect and store excrement while keeping the skin dry and clean, further enhancing the user's quality of life.

[0051] The ostomy bag device disclosed herein exhibits significant technical advantages, primarily reflected in the following aspects: A multi-layered sealing structure design significantly enhances sealing performance, effectively preventing leakage of excrement and protecting the patient's skin; the use of soft medical-grade silicone material and a side-locking mechanism reduces patient discomfort during use; the quick-release structure and quick-lock protrusion design improve operational convenience and efficiency; high-strength materials and anti-slip texture enhance the device's stability and durability; and the flexible protrusion design and independent clamp structure make it adaptable to various application scenarios. In summary, this technical solution significantly improves the overall performance of the ostomy bag device, providing patients with a safer, more comfortable, and more efficient user experience.

[0076] To make the purpose, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described herein are merely illustrative and not intended to limit the scope of this disclosure.

[0077] In the retaining ring assembly of ostomy bags using relevant technologies, a relatively complex mechanical locking method is often used to achieve a stable connection and seal between the ostomy bag and the stoma baseplate. However, traditional locking methods often suffer from complex operation and difficult disassembly and assembly, which not only increases the difficulty of use for patients but may also cause unnecessary trouble during use.

[0078] To simplify assembly and disassembly, based on the design principle of ostomy bags, the connecting rings are typically removed and installed by pushing or pulling towards the patient. This design makes ostomy bag use simpler and more user-friendly, as patients or caregivers can easily connect or disconnect the ostomy bag from the stoma baseplate by gently pushing or pulling the rings. This method improves ease of use and efficiency. In this way, the process of removing and installing ostomy bags becomes simpler and faster, allowing patients to more easily manage their stoma care needs in daily life.

[0079] However, this pull-type ostomy bag connection method also has certain problems, especially during the installation and removal process, which may cause secondary injury to the patient. This secondary injury not only exacerbates their discomfort but may also increase their pain.

[0080] To address the aforementioned issues, the ostomy bag's retaining ring assembly of this disclosure employs a ring-type locking mechanism. Specifically, the retaining ring structure is designed with ergonomics and ease of use in mind, allowing users to easily and quickly attach and detach the ostomy bag. In the locked state, the retaining ring structure securely locks the first and second annular bodies, ensuring a tight seal between the ostomy bag and the stoma baseplate, thereby effectively preventing leakage of excrement and protecting the patient's skin from irritation.

[0081] Furthermore, the ostomy bag retainer assembly of this disclosure possesses excellent adaptability and durability. The retainer structure can be made of high-strength materials as needed, capable of withstanding significant tensile and compressive forces, ensuring that it will not loosen or be damaged during use. Simultaneously, the locking area of ​​the retainer structure is equipped with a quick-release mechanism and / or a quick-lock protrusion, further simplifying the assembly and disassembly process and improving operational efficiency.

[0082] Based on the above technical issues, please refer to Figures 1-16 As shown, the first aspect of this disclosure proposes a ostomy bag clamp assembly that can be disassembled and assembled from the side via the clamp structure 300, which is less likely to cause secondary injury to the patient, improves the patient's comfort, reduces the patient's pain, and improves the sealing performance of the ostomy bag after installation by utilizing multi-layer sealing.

[0083] Reference Figures 1 to 4 In some examples, this disclosure provides a locator assembly for an ostomy bag, the locator assembly including a first annular body 100, a second annular body 200 and a clamping structure 300.

[0084] The first annular body 100 has a first communication port. The first annular body 100 includes a sealing part 110 and a first snap-fit ​​part 120 connected to each other. The sealing part 110 is sealed to the ostomy bag, and the first snap-fit ​​part 120 is disposed on the side of the sealing part 110 away from the ostomy bag.

[0085] The second annular body 200 has a second communication port. The second annular body 200 includes a connecting fitting part 210 and a second snap-fit ​​part 220. The fitting part 210 can fit into a preset position, and the first snap-fit ​​part 120 is adapted to the second snap-fit ​​part 220.

[0086] The clamp structure 300 is movably connected to the first annular body 100 or the second annular body 200. The clamp structure 300 has a groove 330. The two groove walls of the groove 330 can respectively press the first locking part 120 and the second locking part 220 after docking, so that the clamp structure 300 locks the first annular body 100 and the second annular body 200.

[0087] Reference Figures 5 to 9The first snap-fit ​​portion 120 and the second snap-fit ​​portion 220 are provided with at least two sets of annular contact surfaces in their mating areas, and at least two sealing structures are formed between the first snap-fit ​​portion 120 and the second snap-fit ​​portion 220 in the locked state.

[0088] In the above structure, the retaining ring assembly of the ostomy bag disclosed herein can be disassembled and assembled from the side via the retaining structure 300, which is less likely to cause secondary injury to the patient, improves the patient's comfort, and reduces the patient's pain.

[0089] The ostomy bag retainer assembly in the above structure consists of a first annular body 100, a second annular body 200, and a clamp structure 300. Through the cooperation of each component, safety and reliability can be ensured during use.

[0090] Specifically, the first annular body 100 is provided with a first connecting port, which communicates with the ostomy bag. The first annular body 100 includes a sealing part 110 and a first snap-fit ​​part 120. The sealing part 110 is sealed and connected to the ostomy bag to form a whole, effectively preventing leakage of the ostomy bag in the sealing area of ​​the sealing part 110. The first snap-fit ​​part 120 is located on the side of the sealing part 110 away from the ostomy bag, and the first snap-fit ​​part 120 is used to connect with the second annular body 200.

[0091] The ostomy bag and sealing part 110 can be sealed using various methods such as welding and bonding, achieving an integrated connection. The ostomy bag can be designed as a disposable item to meet single-use requirements and avoid potential contamination during reuse. Alternatively, the ostomy bag can be manufactured for multiple reuses, allowing for repeated use through washing and sterilization.

[0092] The second annular body 200 is provided with a second communication port. After the first annular body 100 and the second annular body 200 are connected, the second communication port communicates with the first communication hole. The second annular body includes an adhesive part 210 and a snap-fit ​​part 220. The adhesive part 210 can be fitted to a preset position to ensure the stable installation of the ostomy bag. The preset position can be the patient's skin position. The adhesive part 210 can be fitted by an adhesive method. Specifically, double-sided adhesive can be applied to the side of the adhesive part 210 near the adhesive position, or single-sided adhesive can be applied to the periphery of the adhesive part 210 for bonding. The second snap-fit ​​part 220 is adapted to the first snap-fit ​​part 120. When the second snap-fit ​​part 220 and the first snap-fit ​​part 120 cooperate with each other, they can be pressed, sealed and locked by the clamp structure 300.

[0093] The clamp structure 300 is a component that connects two annular bodies. When the first locking part 120 and the second locking part 220 are engaged, the clamp structure 300 can lock the first locking part 120 and the second locking part 220 through the locking groove 330, thereby achieving relative locking of the first annular body 100 and the second annular body 200.

[0094] The clamp structure 300 can exist independently, and the corresponding model of clamp structure 300 is taken out when locking is required. Alternatively, the clamp structure 300 can be movably connected to the first annular body 100 or the second annular body 200. This disclosure exemplarily describes an embodiment in which the clamp structure 300 is movably connected to the second annular body 200 via a hinge post 230.

[0095] During the locking process of the clamp structure 300, the two groove walls of the groove 330 on the clamp structure 300 can respectively press against the first locking part 120 and the second locking part 220 after docking, thereby achieving the locking function. This side-pressing locking method makes it less likely to generate forces close to or away from the patient's wound during locking or unlocking, greatly reducing the risk of secondary injury to the patient during disassembly and assembly.

[0096] During the locking process, the mating areas of the first latching portion 120 and the second latching portion 220 are compressed, forming at least two sets of annular contact surfaces. In the locked state, these contact surfaces form a sealing structure on at least two sides, further enhancing the sealing effect and reducing the possibility of leakage. Each set of annular contact surfaces includes a first contact surface on the first latching portion 120 and a second contact surface on the second latching portion 220. In the compressed state, the first and second contact surfaces completely abut and form a sealing structure. Each set of annular contact surfaces can form a sealing structure.

[0097] Compared with existing ostomy bag connection methods, the retaining ring assembly of this disclosure has significantly improved the ease of assembly and disassembly and the sealing performance. It not only effectively avoids secondary damage, but also ensures the stability and reliability of the ostomy bag, providing patients with a more comfortable and safer user experience.

[0098] The aforementioned fitting portion 210 can be made of a skin-friendly material and has an adhesive structure to ensure a close fit and comfortable feel with the skin. The fitting portion 210 can also be made of a breathable material, but it must not affect the relative seal of the second annular body 200 on the skin.

[0099] In some examples, at least a portion of the first annular body 100 and the second annular body 200 are made of soft and elastic medical-grade silicone material. This arrangement ensures a good fit between the retaining ring assembly and the ostomy bag and the patient's skin, while reducing pressure and friction on the patient's skin, further improving the patient's user experience.

[0100] Furthermore, the outer circumferential surface of the clamp structure 300 may be provided with anti-slip texture to increase the friction when the user grips it, making it easier for the user to operate the clamp structure 300 with one hand for assembly and disassembly. At the same time, the opening and closing end of the clamp structure 300 is provided with a locking buckle to ensure that the clamp structure 300 is stable and reliable in the locked state, avoiding the risk of the ostomy bag falling off due to accidental loosening.

[0101] The ostomy bag retainer assembly disclosed herein is not only rationally designed and easy to assemble and disassemble, but also effectively reduces patient discomfort during use and improves patients' quality of life.

[0102] Reference Figures 5 to 9 In some examples, the two groove walls of the slot 330 are offset inward so that during the locking process of the clamp structure 300, the two groove walls of the slot 330 can apply the force of the first clamping part 120 and the second clamping part 220 after compression and docking.

[0103] The aforementioned inward offset of the two groove walls allows the clamping structure 300 to generate greater clamping and frictional forces when locking the first annular body 100 and the second annular body 200, thereby ensuring the stability of the clamping ring assembly. Even when subjected to significant external forces during use, the clamping ring assembly is less likely to loosen or fall off, providing more reliable protection for the patient.

[0104] The inward offset of the two groove walls of the slot 330 increases the contact area between the clamp structure 300 and the first locking part 120 and the second locking part 220. Specifically, after compression deformation, it can have a larger contact area, further improving the sealing performance. This design allows the ostomy bag to form a tighter seal after installation, effectively preventing leakage of excrement and maintaining the patient's cleanliness and comfort.

[0105] It is worth mentioning that the material selection for the retaining ring assembly of the ostomy bag disclosed herein can be chosen according to needs. For example, parts of the first annular body 100 and the second annular body 200 can be made of soft and elastic medical-grade silicone material. This material not only has good biocompatibility, reducing irritation and friction to the patient's skin, but also ensures the fit between the retaining ring assembly and the ostomy bag and the patient's skin, improving comfort and stability during use. Parts of the first annular body 100 and the second annular body 200 can also be made of rigid plastic, metal skeleton, or composite materials to ensure that the first annular body 100 and the second annular body 200 have a certain supporting force, forming a more stable and reliable seal in conjunction with the flexible material.

[0106] The clamp structure 300 can be made of high-strength materials, capable of withstanding significant tensile and compressive forces, ensuring it will not be damaged or deformed during use. Simultaneously, the surface of the clamp structure 300 is also equipped with anti-slip textures to increase friction when the user grips it, facilitating one-handed operation for assembly and disassembly. This design not only improves operational convenience but also ensures the stability of the clamp ring assembly in the locked state, preventing the risk of ostomy bag dislodgement due to accidental loosening. Reinforcing ribs can also be added inside the clamp groove 330 as needed.

[0107] The ostomy bag retainer assembly disclosed herein achieves a stable connection, tight seal, and convenient operation through its ingenious structural design and high-quality material selection. This retainer assembly not only effectively reduces patient discomfort during use and improves their quality of life, but also provides healthcare professionals with a simpler and more efficient method for ostomy bag replacement, further enhancing the efficiency and safety of medical care.

[0108] Reference Figures 5 to 9 In other examples, in the first snap-fit ​​portion 120 and the second snap-fit ​​portion 220 after docking, the two pressure surfaces of the first snap-fit ​​portion 120 and the second snap-fit ​​portion 220 opposite to each other are inclined surfaces that are inclined in opposite directions to the outer periphery, so that during the locking process of the clamp structure 300, the two groove walls of the groove 330 can apply a force to compress the first snap-fit ​​portion 120 and the second snap-fit ​​portion 220 after docking.

[0109] The aforementioned inclined surface design allows the clamp structure 300 to apply compressive force more effectively during the locking process, thereby enhancing the connection strength between the first locking portion 120 and the second locking portion 220. Simultaneously, the inclined surface design also helps guide the locking groove 330 of the clamp structure 300 to smoothly align with the first locking portion 120 and the second locking portion 220, making the assembly and disassembly process smoother and further improving operational convenience.

[0110] In practical use, patients or medical staff can easily lock or unlock the ostomy bag's locking ring assembly by simply sliding the clamp structure 300 along the inclined contact portion 120 and the second contact portion 220. This design not only simplifies the operation process but also reduces the potential risk of injury to patients due to improper operation.

[0111] Furthermore, the inclined surface design allows for a more even distribution of pressure on the occluder assembly under stress, preventing damage to the occluder assembly or the patient's skin caused by excessive localized pressure. This design further enhances the safety and reliability of the ostomy bag occluder assembly, providing patients with a more comfortable and reassuring user experience.

[0112] The ostomy bag retainer assembly disclosed herein achieves a stable connection, convenient assembly and disassembly, and excellent sealing performance by employing an inward offset of the two groove walls of the retainer groove 330 and an inclined surface arrangement of the opposing pressure-bearing surfaces of the first retaining portion 120 and the second retaining portion 220. This retainer assembly not only meets patients' needs for comfort and safety in using ostomy bags but also provides medical staff with a more efficient and simpler method for changing ostomy bags, further improving the quality and efficiency of medical care.

[0113] Furthermore, the two pressure-bearing surfaces include a first pressure-bearing surface 121 disposed on the first snap-fit ​​portion 120 and a second pressure-bearing surface 221 disposed on the second snap-fit ​​portion 220. The first pressure-bearing surface 121 is squeezed by one of the groove walls of the snap-fit ​​groove 330 during the locking process of the snap-fit ​​structure 300, and the second pressure-bearing surface 221 is squeezed by the other groove wall of the snap-fit ​​groove 330 during the locking process of the snap-fit ​​structure 300. During the compression process, the first snap-fit ​​portion 120 and the second snap-fit ​​portion 220 are relatively close to each other and deformed by compression to form at least two layers of sealing structure.

[0114] Reference Figures 10 to 15 In some examples, the first latching portion 120 is provided with at least one annular first protrusion 122 and at least one first groove 123 alternately on the side of the second latching portion 220 near the first latching portion 120. The second latching portion 220 is provided with at least one annular second protrusion 222 and at least one second groove 223 alternately on the side of the first latching portion 120.

[0115] When the first latching portion 120 and the second latching portion 220 are mated, a portion of the first protrusion 122 abuts against the second groove 223 and forms at least two sets of annular contact surfaces, or a portion of the second protrusion 222 fills the first groove 123 and forms at least two sets of annular contact surfaces to form at least two layers of sealing structure.

[0116] The aforementioned multi-layer sealing structure significantly enhances the sealing performance of the ostomy bag retainer assembly, effectively preventing leakage. The alternating protrusions and grooves on the first and second retaining portions 120 and 220 ensure a tight fit after connection, maintaining a good seal even under pressure changes or movement. Furthermore, the annular contact surface not only increases the sealing area but also improves the uniformity and stability of the seal, making the ostomy bag safer and more reliable during use. Therefore, this ostomy bag retainer assembly represents an innovation and improvement in sealing performance, providing users with a superior user experience.

[0117] Reference Figures 10 to 15 In some examples, the first latching portion 120 is provided with a first protrusion 122. The second latching portion 220 is provided with a second groove 223.

[0118] The first protrusion 122 can abut against the second groove 223, and the top of the first protrusion 122 contacts the bottom of the second groove 223, forming a first sealing structure 400. The two sides of the first protrusion 122 abut against the two groove walls of the second groove 223 respectively, forming a second sealing structure 500 and a third sealing structure 600.

[0119] The aforementioned structure creates a multi-layered, multi-dimensional sealing system, further enhancing the reliability and durability of the ostomy bag retainer assembly. The fit between the first protrusion 122 and the second groove 223 not only ensures a tight seal but also reduces wear and loosening that may occur due to prolonged use or improper operation. The direct contact between the top of the first protrusion 122 and the bottom of the second groove 223 forms the first sealing structure 400, effectively preventing leakage. The tight fit between the two sides of the first protrusion 122 and the groove wall of the second groove 223 forms a second sealing structure 500 and a third sealing structure 600, providing multiple layers of protection for the ostomy bag. This multi-layered sealing structure elevates the performance of the ostomy bag retainer assembly to a new level, meeting users' urgent needs for high-quality, high-reliability ostomy bags.

[0120] Reference Figures 10 to 15 In some examples, the first latching portion 120 is provided with a first groove 123 and two first protrusions 122 provided on both sides of the first groove 123. The second latching portion 220 is provided with a second groove 223 and two second protrusions 222 provided on both sides of the second groove 223.

[0121] The top of one of the first protrusions 122 can abut against the bottom of the second groove 223, forming a first sealing structure 400. The two sides of the first protrusion 122 abut against two second protrusions 222 respectively, forming a second sealing structure 500 and a third sealing structure 600.

[0122] The top of the second protrusion 222, which abuts against the first groove 123, can abut against the bottom of the first groove 123, forming a fourth sealing structure. Alternatively, the side of the second protrusion 222 can abut against another first protrusion 122, forming a fifth sealing structure.

[0123] The aforementioned structure embodies a more complex snap-fit ​​and sealing mechanism, which not only enhances the structural stability of the ostomy bag retainer assembly but also further improves sealing performance. The first groove 123 on the first snap-fit ​​portion 120 and the first protrusions 122 on both sides cooperate with the second groove 223 on the second snap-fit ​​portion 220 and the second protrusions 222 on both sides to form a multi-layered, multi-dimensional sealing network. The direct contact between one of the first protrusions 122 and the bottom of the second groove 223 constitutes the first sealing structure 400, effectively preventing leakage. Simultaneously, the first protrusion 122 and the second protrusions 222 on both sides fit tightly together, forming the second sealing structure 500 and the third sealing structure 600 respectively, providing additional protection for the use of the ostomy bag.

[0124] The second protrusion 222, which abuts against the first groove 123, has its top tightly fitted to the bottom of the first groove 123, forming a fourth sealing structure and further enhancing the sealing effect. Alternatively, the side of the second protrusion 222 can be in close contact with another first protrusion 122, forming a fifth sealing structure. This arrangement can provide more flexible sealing options in specific situations to meet the needs of different users.

[0125] In some examples, portions of the first protrusion 122 and / or the second protrusion 222 are flexible structures. During the mutual compression of the first snap-fit ​​portion 120 and the second snap-fit ​​portion 220, the first protrusion 122 and / or the second protrusion 222 elastically deform and form a multi-layer sealing structure.

[0126] The aforementioned flexible structure allows the protruding portion to adaptively adjust according to the shape and pressure distribution of the locking part during the locking process. When the first locking part 120 and the second locking part 220 are pressed against each other, the flexible protrusion will undergo elastic deformation, thereby fitting more tightly between the groove and the adjacent protrusion, forming a denser and more stable sealing layer.

[0127] This deformation not only enhances the sealing effect but also helps improve the adaptability and durability of the retainer assembly, enabling it to better adapt to ostomy bags of different shapes and sizes, and to cope with minor deformations that may occur during long-term use. Furthermore, the elastic deformation capability of the flexible protrusions effectively mitigates impact forces during the clamping process, reducing the risk of damage to the ostomy bag and retainer assembly, and providing users with a safer and more reliable experience.

[0128] Reference Figure 16 In some examples, the locking area of ​​the clamp structure 300 is provided with a quick-release structure 340. And / or, quick-lock protrusions 350 are provided on both sides of the locking area of ​​the clamp structure 300.

[0129] The aforementioned quick-release structure 340 and / or quick-lock protrusion 350 greatly facilitate users when using the ostomy bag's retainer assembly. The quick-release structure 340 allows users to quickly and easily release the retainer structure 300 when needed, without complicated operations or tools, significantly saving time and effort. Simultaneously, the quick-lock protrusion 350 ensures the stability and security of the retainer structure 300 in the locked state, preventing unlocking due to accidental contact or slight vibration. This design not only improves the ease of use of the retainer assembly but also enhances its reliability and durability in practical applications, providing users with a more convenient and efficient user experience.

[0130] The quick-release structure 340 can have a slightly raised spring-loaded structure, or a handle-groove structure that is not easily disturbed by external forces, depending on the specific requirements. The quick-lock protrusion 350 facilitates quick locking and force application of the clamp structure 300. The surface of the quick-lock protrusion 350 that contacts the fingers can be provided with an anti-slip structure 360 ​​to further improve locking efficiency.

[0131] Reference Figure 16 In some examples, the first annular body 100 and / or the second annular body 200 are provided with hinge posts 230, and the clamp structure 300 is hinged to the hinge posts 230. A locking ring 231 can be provided on the hinge posts 230 as needed to prevent the clamp structure 300 from accidentally detaching from the hinge posts 230.

[0132] This hinged design allows the clamp structure 300 to move and lock flexibly between the first annular body 100 and the second annular body 200, thereby further improving the adjustability and adaptability of the ostomy bag device. Users can easily lock and unlock the clamp structure 300 according to actual needs, improving the efficiency of ostomy bag replacement.

[0133] In other examples, the clamp structure 300 is set independently, and when the first annular body 100 and the second annular body 200 are engaged, the clamp structure 300 locks the first engaging part 120 and the second engaging part 220 after they are engaged.

[0134] At this point, the clamp structure 300 exists as an independent component, not relying on any part of the first annular body 100 or the second annular body 200 for fixation or connection. When the first annular body 100 and the second annular body 200 need to be engaged, the user can place the clamp structure 300 between the engaged first engagement portion 120 and the engaged second engagement portion 220, and achieve quick and stable locking through the quick-release structure 340 and the quick-locking protrusion 350. This independently configured clamp structure 300 provides greater flexibility and adaptability, allowing the clamp ring assembly to be applied to more different ostomy bag devices and designs. Simultaneously, the independently configured clamp structure 300 also facilitates user replacement or maintenance, further improving the ease of use and practicality of the ostomy bag device.

[0135] In some examples, the clamp structure 300 is a split clamp, which includes a first clamp 310 and a second clamp 320. The first end of the first clamp 310 and the first end of the second clamp 320 are both hinged to the hinge post 230. In the locked state, the second end of the first clamp 310 and the second end of the second clamp 320 are detachably connected.

[0136] The split-type clamp structure 300 comprises two main parts: a first clamp 310 and a second clamp 320. Specifically, one end of the first clamp 310 and one end of the second clamp 320 are hinged to the same hinge post 230. When the clamp structure 300 is in the locked state, the other end of the first clamp 310 and the other end of the second clamp 320 can be detachably connected. This design provides the clamp structure 300 with a degree of flexibility and convenience during use, while also ensuring its stability and reliability in the locked state.

[0137] Furthermore, the first clamp 310 and the second clamp 320 are typically made of high-strength, corrosion-resistant materials to ensure their durability and service life in various harsh environments. This choice of materials not only enhances the overall strength of the clamp structure 300 but also ensures its stability and safety in long-term applications.

[0138] In the locking mechanism of the clamp structure 300, a dedicated locking element, such as a latch, bolt, or quick-clamping device, is typically provided between the second end of the first clamp 310 and the second end of the second clamp 320. These locking elements are designed to allow users to easily and securely connect the two clamp parts together when needed, forming a complete ring clamp, thereby effectively securing or protecting the required pipes, cables, or other cylindrical components. For example, the locking element can be a clamp fixing block 370 located in the locking position after the clamp structure 300 has been wrapped at least once. The clamp fixing block 370 can be configured as a wedge-shaped protrusion with a snap-fit ​​surface and a guide surface. The clamp fixing block 370 enhances the stability of the clamp structure 300, maintaining a good locked state even during prolonged use or activity, preventing the ostomy bag from accidentally falling off or loosening. These features not only improve the practicality and comfort of the ostomy bag device but also provide users with a more reassuring and reliable user experience.

[0139] Meanwhile, this split-type clamp structure 300 is also easy to install and disassemble. Users can easily open or close the clamp structure 300 by simply operating the locking mechanism, without the need for complicated tools or cumbersome procedures. This convenience greatly improves work efficiency and reduces the cost of maintaining and replacing the clamp structure 300.

[0140] In another example, the clamp structure 300 is an integral clamp, with the first end of the clamp structure 300 hinged to the hinge post 230, and the second end of the clamp structure 300 detachably connected to the first end of the clamp structure 300 after wrapping around the first annular body 100 and / or the second annular body 200 at least once.

[0141] In the above structure, the clamp structure 300 is designed as an integral clamp. The first end of this clamp structure 300 is hinged to the hinge post 230. The second end of the clamp structure 300 wraps around the first annular body 100 and / or the second annular body 200 at least once, allowing for a detachable connection at the first end of the clamp structure 300. This design provides the clamp structure 300 with flexibility and adjustability during use, while also facilitating installation and disassembly. This structure effectively fixes and stabilizes the first annular body 100 and the second annular body 200, ensuring the stability and reliability of the entire device.

[0142] Furthermore, the aforementioned integrated clamp structure 300 can be manufactured using high-strength materials, ensuring that it is not easily deformed or damaged when subjected to large pressure or tension, thereby further improving the durability and safety of the device. The hinge at the first end of the clamp structure 300 to the hinge post 230 ensures smooth rotation of the clamp when it surrounds the annular body, and also allows the user to adjust the tightness of the clamp as needed.

[0143] After the clamp structure 300 is completed by wrapping around the second end and connecting it to the first end, a stable closed-loop structure is formed. This structure not only enhances the fixing effect of the ring-shaped body, but also effectively prevents loosening or falling off due to vibration or external impact. In addition, the detachable connection method allows users to easily replace or maintain the clamp structure 300 when needed, greatly improving work efficiency.

[0144] Reference Figure 17 In some examples, pull ring structures are provided on both sides of the second ring-shaped body, and the two pull ring structures can work with the elastic rope to bind the second ring-shaped body to the human torso.

[0145] The aforementioned pull-loop structure not only facilitates the user's attachment of the ostomy bag to the body, but also, through the elasticity of the cord, adapts to patients of different body types, ensuring the stability and comfort of the device. The pull-loop design is simple and easy to use; users simply thread the elastic cord through the pull-loop and adjust the tightness appropriately to achieve a secure fixation. Furthermore, the pull-loop structure allows for easy replacement or adjustment of the ostomy bag, greatly improving convenience and efficiency.

[0146] Reference Figures 18 to 21 In some examples, the clamp structure 300 is a double-locking structure. The clamp structure 300 is disassembled and assembled through a combination of double protrusions and double locking grooves. During the locking process, the size of the wedge-shaped protrusion 371 that engages first is larger than the size of the wedge-shaped protrusion 371 that engages later. The double locking grooves are also corresponding to the wedge-shaped locking grooves 372. In the event of accidental contact or loosening, even if one set of wedge-shaped protrusions 371 and wedge-shaped locking grooves 372 disengages, the other set of wedge-shaped protrusions 371 and wedge-shaped locking grooves 372 will still maintain the clamp's lock, further reducing the possibility of the clamp structure 300 unlocking due to accidental contact, ensuring the stable locking of the clamp structure 300, and thus improving the stability of the retaining ring structure.

[0147] Furthermore, this double-locking structure design also considers ease of use and safety. During assembly and disassembly, the user can gradually lock the clamp structure 300 by first engaging the larger wedge-shaped protrusion 371 and then engaging the smaller wedge-shaped protrusion 371. This gradual locking method not only makes the assembly and disassembly process smoother but also effectively prevents damage or unlocking of the clamp structure 300 due to improper operation. At the same time, the cooperative structure of the double protrusions and double locking grooves makes the clamp structure 300 more stable after locking, able to withstand greater external forces and pressures, further improving the stability and durability of the entire device.

[0148] It should be noted that the two wedge-shaped slots 372 can be set on the quick-release structure 340. The quick-release structure 340 itself has a certain elasticity. After the wedge-shaped protrusion 371 that is engaged later comes off, under the action of the elasticity of the quick-release structure 340, the disengaged wedge-shaped protrusion 371 can still engage with the subsequent wedge-shaped slot 372 to achieve the effect of preventing disengagement. At this time, the two wedge-shaped protrusions 371 can also be set to the same size. The specific size can be selected according to actual needs, and is not limited to the above-mentioned case where the size of the wedge-shaped protrusion 371 that engages first is larger than the size of the wedge-shaped protrusion 371 that engages later.

[0149] This design not only increases the flexibility of the clamp structure 300 but also further enhances its anti-disengagement performance. Under the elastic force of the quick-release structure 340, even if one of the wedge-shaped protrusions 371 accidentally disengages, it can be quickly captured by the other wedge-shaped locking groove 372, thus preventing the clamp structure 300 from completely unlocking. Simultaneously, by setting the two wedge-shaped protrusions 371 to the same size, not only is the manufacturing process simplified, but users also do not need to distinguish the order of operation, further improving ease of use. This design is not only suitable for the clamping ring assembly of ostomy bags but can also be widely used in other situations requiring stable locking and easy assembly / disassembly, demonstrating its broad applicability and practicality.

[0150] Secondly, this disclosure also provides an ostomy bag device, including the above-mentioned ostomy bag retaining ring assembly and the ostomy bag, wherein the ostomy bag and the retaining ring assembly are sealed together.

[0151] The aforementioned ostomy bag device includes a retaining ring assembly for the ostomy bag as described above, and an ostomy bag. Specifically, the ostomy bag device tightly connects the ostomy bag and the retaining ring assembly through a sealing connection. This design not only ensures the stability and sealing of the ostomy bag but also facilitates user use and replacement, thereby improving overall comfort and practicality. Through this structure, the ostomy bag device can effectively collect and store excrement while keeping the skin dry and clean, further enhancing the user's quality of life.

[0152] The ostomy bag device disclosed herein exhibits significant technical advantages, primarily manifested in the following aspects: A multi-layered sealing structure design significantly enhances sealing performance, effectively preventing leakage of excrement and protecting the patient's skin; the use of soft medical-grade silicone material and a side-locking mechanism reduces patient discomfort during use; the quick-release structure 340 and quick-lock protrusion 350 improve operational convenience and efficiency; high-strength materials and anti-slip texture enhance the device's stability and durability; and the flexible protrusion design and independent clamp structure 300 adapt it to various application scenarios. In summary, this technical solution significantly improves the overall performance of the ostomy bag device, providing patients with a safer, more comfortable, and more efficient user experience.

[0153] Specifically, the ostomy bag device having the above-mentioned retaining ring assembly has the following technical effects:

[0154] 1. Improve sealing performance and reduce leakage risk

The split or integrated clamp structure 300 provides flexible options for easy installation and removal.

[0160] 4. Enhance the stability and durability of the device.

[0161] The clamp structure 300 is made of high-strength material, capable of withstanding significant tensile and compressive forces, ensuring it will not be damaged or deformed during use. Combined with anti-slip textures and reinforcing ribs, it enhances the clamp's stability and reliability. The contact part 210 uses skin-friendly material and features an adhesive structure, ensuring a close fit to the skin while maintaining breathability, improving device stability and enhancing the user experience.

[0162] 5. Adaptable to various application scenarios

[0163] The flexible protrusion design of the retainer assembly allows it to adapt to ostomy bags of different shapes and sizes, offering high adaptability to meet the needs of various patients. The independently configured clamp structure 300 provides possibilities for more diverse ostomy bag designs, satisfying personalized requirements.

[0164] This disclosure significantly improves the overall performance of the ostomy bag device by optimizing sealing performance, reducing discomfort, enhancing ease of operation, increasing stability and durability, and adapting to diverse needs, providing patients with a safer, more comfortable, and more efficient user experience.
