Description

Technical Field

[0001] This invention belongs to the field of medical urine bag wearing technology, specifically relating to a concealed urine collection bag wearing device. Background Technology

[0002] Urine collection bags, used for urine drainage and temporary storage, are commonly used by patients undergoing catheterization, postoperative recovery patients, people with limited mobility, and those requiring continuous urination management. In practical use, to facilitate daily activities and reduce the inconvenience of exposure, some urine collection bags need to be worn and secured to the legs or other parts of the body, allowing for urine collection and storage while the bag is in contact with the body. This adapts to applications such as home care, rehabilitation activities, and daily travel.

[0003] Existing wearable urine collection bags typically need to meet basic requirements such as close-fitting wear, stable fixation, and reliable flow connection during actual use. However, during walking, sitting / lying transitions, or frequent leg movements, the wearing area continuously deforms and shifts, affecting the urine collection bag itself and its flow connection. In existing technologies, wearable urine collection bag devices generally suffer from the following problem at the overall usage level: insufficient adaptability between the device and human activity while worn, easily leading to decreased stability of the urine collection bag's fixation and flow connection, thus affecting concealment, comfort, and reliability of continuous use. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a concealed urine collection bag wearable device that can adapt to leg wear scenarios and maintain the overall stability of the urine collection bag and the stability of the flow connection during human activity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A concealed urine collection bag wearable device includes a strap, on the surface of which a urine collection bag is attached. The urine collection bag is tightly fitted to the outer surface of the strap. Hinges are provided on both sides of the surface of the strap. An elastic band is rotatably mounted on the surface of one of the hinges. The end of the elastic band is detachably engaged with the hinge on the other side so that the elastic band covers the upper and lower edges of the urine collection bag and fixes the urine collection bag. The top of the urine storage bag is equipped with a drain tube, and the bottom of the urine storage bag is connected to a drain tube. A fixing block is provided above the surface of the strap. The fixing block is provided with a guide shaft, a slide groove and a slider for guiding and limiting the flow tube. A spring is provided in the slide groove to apply a pushing force to the slider towards one side of the slide groove. A rubber bracket is provided below the surface of the fixing block for holding the flow tube, so that the flow tube is in a taut state after being guided and is buffered by the movement of the slider and the compression of the spring when it is pulled.

[0006] Furthermore, multiple connecting straps are sewn onto one side of the strap, and Velcro is provided on the inner side of the connecting strap. The Velcro is adhered to the outer surface of the strap to fix the strap to the lower leg.

[0007] Furthermore, the end of the elastic band is provided with a first slot, which is adapted to the hinge rod on the other side. The first slot has a C-shaped structure and is larger than a semicircle to keep the elastic band and the hinge rod fastened and fixed.

[0008] Furthermore, a protruding plate is provided at the end of the first slot, and compression protrusions are evenly provided on the inner side of the first slot. The compression protrusions are used to compress and fix the upper and lower edges of the urine storage bag.

[0009] Furthermore, the drainage tube is pluggable and installed on the top of the urine storage bag, and the drainage tube is placed outside the elastic band to prevent the elastic band from squeezing the drainage tube and causing internal blockage; the drain tube is a normally closed structure.

[0010] Furthermore, guide shafts are rotatably mounted on one side of the surface of the fixing block, and end plates are provided at the ends of the guide shafts; a sliding groove is laterally opened at the center of the surface of the fixing block, one side of the sliding groove is open, and a stop block is installed at the open end of the sliding groove to block the open end of the sliding groove.

[0011] Furthermore, the slider is slidably installed in the groove, and a movable shaft is rotatably installed on the outer side of the slider; the spring is placed horizontally inside the groove, and one end of the spring abuts against the slider to apply a pushing force toward the stop to the slider.

[0012] Furthermore, the rubber bracket is fixed below the surface of the fixing block, and the surface of the rubber bracket has a second slot with one side open. The inner wall of the second slot is evenly provided with anti-slip protrusions. The guide tube passes through the second slot and passes around the lower guide shaft, the movable shaft and the upper guide shaft in sequence from bottom to top. The anti-slip protrusions are used to prevent the guide tube from falling off due to pulling.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a urine collection bag that fits snugly against the outer surface of the strap, and elastic bands at the top and bottom edges of the bag that cooperate with the sides of the strap for fixation. This ensures that the urine collection bag not only adheres to the corresponding position on the leg when worn, but also maintains stable installation through the upper and lower edge limits. Thus, during walking, sitting / lying transitions, or continuous leg movement, the urine collection bag is less likely to shift significantly or tilt relative to the strap. This addresses the problem of insufficient overall stability in existing wearable urine collection bag devices during human activity, providing a stable fixation solution adapted to leg-wearing scenarios.

[0014] This invention provides a controlled placement of the drainage tube at the top of the urine collection bag, along with a structure above the bag that holds, guides, and cushions the tube's movement. This allows the drainage tube to maintain a controlled path while the device is worn. The tube first passes through a holding section for stable connection, then through a guiding section to form a relatively regular trajectory. When subjected to external pulling, the tube is cushioned by the movement of movable components and the compression of elastic components. Thus, even if the tube is affected by leg movements or external pulling during user activity, the likelihood of direct tension on the drainage connection is reduced. This provides a solution that balances drainage tube path control and tension cushioning, addressing the problem of decreased stability in existing wearable urine collection bag devices during human activity.

[0015] This invention integrates the urine bag fixing structure and the flow guiding and buffering structure into the corresponding area of ​​the strap, enabling the device to simultaneously maintain stable wear of the urine bag and stable flow connection under close-fitting conditions. Therefore, the device is better suited for concealed urine collection scenarios worn on the legs, maintaining overall reliability during continuous wear and daily activities.

[0018] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. Example 1

[0019] See Figures 1 to 7 A concealed urine collection bag wearable device includes a strap 1, with multiple connecting straps 11 sewn onto one side of the strap 1. Velcro 12 is provided on the inner side of each connecting strap 11. A urine collection bag 2 is mounted on the surface of the strap 1, fitting snugly against the outer surface of the strap 1. Hinges 13 are provided on both sides of the strap 1. An elastic band 3 is rotatably mounted on the surface of one hinge 13, and the end of the elastic band 3 is detachably connected to the hinge 13 on the other side. A drain tube 21 is pluggably installed at the top of the urine collection bag 2, and a drainage tube 2 is connected to the bottom of the urine collection bag 2. 2; A fixing block 4 is provided above the surface of the strap 1. A guide shaft 41 is rotatably installed on one side of the surface of the fixing block 4. A groove 42 is opened horizontally in the center of the surface of the fixing block 4. A slider 5 is slidably installed in the groove 42. A spring 6 is provided inside the groove 42. A rubber seat 44 is fixed below the surface of the fixing block 4. The guide tube 21 passes through the rubber seat 44 and then passes from bottom to top around the lower guide shaft 41, the movable shaft 51 on the outer side of the slider 5, and the upper guide shaft 41 in sequence to form a guide path of the guide tube 21 that is adapted to the leg wearing state.

[0020] When installing the strap 1 for leg wear, first, attach the strap 1 to the outside of the user's calf. Then, wrap multiple connecting straps 11 around the outside of the calf, and make the Velcro 12 on the inner side of the connecting straps 11 adhere to the outer surface of the strap 1, thereby completing the basic fixation of the strap 1 on the calf. Since the urine bag 2 is directly installed on the surface of the strap 1, and the urine bag 2 is tightly attached to the outer surface of the strap 1, after the strap 1 is fixed, the urine bag 2 can be kept in the corresponding position on the leg along with the strap 1, thus meeting the requirements of close-fitting wear and concealed installation.

[0021] After the installation position of the urine storage bag 2 is determined, the elastic band 3 located on one side of the hinge rod 13 is flipped towards the urine storage bag 2, so that the upper and lower elastic bands 3 cover the upper and lower edges of the urine storage bag 2 respectively. Then, the end of the elastic band 3 is detachably engaged with the other side of the hinge rod 13 to clamp and fix the urine storage bag 2 to the surface of the strap 1. The elastic band 3 forms a pressing relationship between the upper and lower edges of the urine storage bag 2, which can further limit the local lifting and positional displacement of the urine storage bag 2 during leg activities while providing a base for attachment with the strap 1, so that the urine storage bag 2 and the strap 1 maintain a stable fit.

[0022] After the urine storage bag 2 is fixed, the drainage tube 21 is plugged into the top of the urine storage bag 2, and the drainage tube 21 is positioned outside the elastic band 3 to avoid the elastic band 3 compressing the drainage tube 21. Then, the drainage tube 21 is introduced into the rubber retainer 44 below the fixing block 4, so that the drainage tube 21 passes through the second groove 45 opened on the surface of the rubber retainer 44. The drainage tube 21 is then continued upwards, passing sequentially from bottom to top around the lower guide shaft 41, the movable shaft 51, and the upper guide shaft 41. Through the coordinated arrangement of the fixing block 4, guide shaft 41, movable shaft 51, slide groove 42, slider 5, spring 6, and rubber retainer 44, the drainage tube 21 forms a controlled guiding and movement path above the urine storage bag 2, thereby preventing the drainage tube 21 from swinging directly in the air during leg movements.

[0023] In a typical use case, after the urine bag 2 is fixed to the surface of the strap 1, the drainage tube 21 remains inserted at the top of the urine bag 2, and the drainage tube 22 remains normally closed. The user can walk, sit or lie down, or engage in daily activities while wearing the device. When the leg bends, swings, or the strap 1 changes position, the drainage tube 21 adjusts its position synchronously along the path defined by the guide shaft 41 and the movable shaft 51. If the drainage tube 21 is subjected to continuous pulling, it will drive the movable shaft 51 and the slider 5 to move within the groove 42. At the same time, the spring 6 is compressed inside the groove 42 to buffer the pulling force on the drainage tube 21. After the external pulling weakens, the spring 6 pushes the slider 5 back, and the drainage tube 21 returns to a relatively taut state. Through the coordination of the above-mentioned overall structure, a complete action chain adapted to the leg wearing scenario is formed between the strap 1, the urine bag 2, and the drainage tube 21. Example 2

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The strap 1, serving as the basic wearable component that directly contacts the human leg, is located on the inner side of the overall structure. Multiple connecting straps 11 are distributed along one side of the strap 1, and are sewn together. Velcro 12 on the inner side of the connecting straps 11 adheres to the outer surface of the strap 1. With multiple connecting straps 11 distributed along the length of the strap 1, they can wrap and fix at different heights of the lower leg, thus creating a relatively stable attachment of the strap 1 to the outer periphery of the leg. This arrangement allows the strap 1, when used as the mounting base for the urine storage bag 2, not only to provide a secure wrapping mechanism but also to offer a stable support surface for the subsequent pressure of the elastic band 3 on the urine storage bag 2.

[0025] A urine storage bag 2 is mounted on the surface of the strap 1, and the urine storage bag 2 fits tightly against the outer surface of the strap 1. Hinged rods 13 are positioned on both sides of the surface of the strap 1, respectively, within the mounting area of ​​the urine storage bag 2. An elastic band 3 is rotatably mounted on the surface of one of the hinged rods 13. The elastic band 3 can rotate and unfold around the corresponding hinged rod 13 to provide opening space when the urine storage bag 2 is inserted and removed. This mounting arrangement ensures that the elastic band 3 does not detach from the strap 1 when open, and can cross the edge of the urine storage bag 2 to provide support when closed, thus balancing the ease of assembly and the stability of the urine storage bag 2.

[0026] The elastic band 3 has a first slot 31 at its end, which is adapted to the hinge rod 13 on the other side. The first slot 31 has a C-shaped structure and is larger than a semicircle. This structural relationship allows the first slot 31 to maintain a relatively stable fastening state after being fastened to the corresponding hinge rod 13, relying on its own opening shape, thereby preventing the elastic band 3 from coming off by itself during normal activities. The protruding plate 32 at the end of the first slot 31 is located on the outer side of the end of the elastic band 3. The protruding plate 32 facilitates pulling operations during wearing and disassembly, making it easier for the elastic band 3 to open and close.

[0027] See Figure 5 The inner side of the first slot 31 is evenly provided with compression protrusions 33. After the upper and lower elastic bands 3 cover the upper and lower edges of the urine storage bag 2, the compression protrusions 33 press against the upper and lower edge areas of the urine storage bag 2. Since the compression protrusions 33 are evenly distributed along the inner side of the first slot 31, after being fastened and fixed, the compression protrusions 33 can form a relatively dispersed pressing contact relationship at the edge of the urine storage bag 2, thereby clamping and limiting the upper and lower edges of the urine storage bag 2 in conjunction with the covering effect of the elastic band 3 itself. This fixing method does not simply rely on the surface of the strap 1 to adhere to the urine storage bag 2, but further forms an edge pressing relationship in the upper and lower direction on the outside of the urine storage bag 2, so it is more suitable for fixing the urine storage bag 2 in the environment of leg activity.

[0028] In practical use, after the strap 1 is fixed to the lower leg with the connecting strap 11 and Velcro 12, the elastic band 3 can be turned outwards first, and then the urine bag 2 can be placed on the predetermined area on the surface of the strap 1, so that the urine bag 2 fits against the outer surface of the strap 1; then, the upper and lower elastic bands 3 are turned towards the urine bag 2 respectively, and the first slot 31 is fastened to the corresponding hinge rod 13, thus completing the upper and lower edge limiting of the urine bag 2. Through the coordinated cooperation between the strap 1, hinge rod 13, elastic band 3, first slot 31, convex plate 32 and compression protrusion 33, the urine bag 2 can maintain a fixed state of both close attachment and edge pressing in the leg wearing scenario. Example 3

[0029] See Figure 1 , Figure 2 , Figure 6 and Figure 7 A drain tube 21 is pluggable at the top of the urine storage bag 2, located outside the elastic band 3. A normally closed drain tube 22 is connected to the bottom of the urine storage bag 2. The pluggable connection between the drain tube 21 and the urine storage bag 2 facilitates quick assembly during the donning and installation process. Because the drain tube 21 is located outside the elastic band 3, the elastic band 3 does not directly press against the drain tube 21 when securing the urine storage bag 2, thus maintaining independent guiding space for the drain tube 21 at the top of the urine storage bag 2. The drain tube 22 is located at the bottom of the urine storage bag 2 and remains normally closed, used for drain control after urine collection is complete.

[0030] The fixing block 4 is positioned above the surface of the strap 1, directly above the urine storage bag 2. Guide shafts 41 are rotatably mounted on one side of the fixing block 4, both vertically and horizontally. End plates 411 are provided at the ends of the guide shafts 41. The two guide shafts 41 are spaced apart vertically, allowing the drainage tube 21 to form an upward winding path as it passes through the area of ​​the fixing block 4. The end plates 411 are located at the ends of the guide shafts 41, and they axially limit the drainage tube 21 as it rotates around the guide shafts 41, thereby reducing the possibility of the drainage tube 21 detaching from the end of the guide shafts 41.

[0031] A groove 42 is transversely formed at the center of the surface of the fixed block 4. One side of the groove 42 is open, and a stop block 43 is installed at the open end of the groove 42 to seal it. The slider 5 is slidably installed in the groove 42. A movable shaft 51 is rotatably mounted on the outer side of the slider 5. A spring 6 is horizontally placed inside the groove 42, with one end of the spring 6 abutting against the slider 5. Since the slider 5 can move along the groove 42, the movable shaft 51 can change position synchronously with the slider 5. Therefore, the movable shaft 51 not only serves as an intermediate guide component in the path of the guide tube 21, but also as a movable load-bearing component when the guide tube 21 is subjected to force. After the stop block 43 is set at the open end of the groove 42, it can limit the range of motion of the slider 5 and, together with the fixed block 4, maintain the assembly integrity of the internal components of the groove 42.

[0032] A rubber retainer 44 is fixed below the surface of the fixing block 4. The rubber retainer 44 has a second retaining groove 45 with one open side. Anti-slip protrusions 46 are evenly distributed on the inner wall of the second retaining groove 45. The guide tube 21 passes through the second retaining groove 45 and then passes sequentially from bottom to top around the lower guide shaft 41, the movable shaft 51, and the upper guide shaft 41. The rubber retainer 44 is located at the beginning of the guide tube 21's guide path. The second retaining groove 45 provides space for the guide tube 21 to engage. The anti-slip protrusions 46 form a frictional contact with the outer surface of the guide tube 21, making it difficult for the guide tube 21 to detach from the second retaining groove 45 under normal pulling. Because the rubber retainer 44 is located below the fixing block 4, the guide tube 21 can first be initially held by the second retaining groove 45 before entering the guide area formed by the guide shaft 41 and the movable shaft 51. Therefore, the overall path of the guide tube 21 is more clearly defined.

[0033] In the specific use of this structure, after the drainage tube 21 is inserted into the urine storage bag 2, the drainage tube 21 is pressed into the second slot 45, and the drainage tube 21 continues to move upwards around the lower guide shaft 41, the movable shaft 51, and the upper guide shaft 41. At this time, the spring 6 applies a pushing force to the slider 5 towards the stop block 43, the slider 5 remains in the corresponding initial position, and the movable shaft 51 remains in the normal guiding position. The drainage tube 21 forms a relatively taut arrangement between the rubber seat 44, the two guide shafts 41, and the movable shaft 51. When the user moves their legs and the drainage tube 21 is pulled, the drainage tube 21 applies a pulling force to the movable shaft 51, and the movable shaft 51 drives the slider 5 to move along the slide groove 42. The spring 6 is compressed in the slide groove 42. When the pulling force weakens, the spring 6 pushes the slider 5 back to its original position, the movable shaft 51 returns to its normal position, and the drainage tube 21 is once again in the guided state. Through the continuous cooperation between the guide tube 21, the fixing block 4, the guide shaft 41, the end plate 411, the slide 42, the stop block 43, the slider 5, the movable shaft 51, the spring 6, the rubber seat 44, the second slot 45 and the anti-slip protrusion 46, the guide tube 21 can complete the guiding, limiting and tension buffering action process in the leg wearing environment.

[0034] The working principle of this invention is as follows: When in use, first wrap the strap 1 around the outside of the user's calf, and then wrap multiple connecting straps 11 around it and attach them to the outer surface of the strap 1 through the Velcro 12 on the inner side of the connecting strap 11, thereby fixing the strap 1 to the calf and providing a stable wearing base for the urine storage bag 2 and its related drainage structure.

[0035] Subsequently, the urine storage bag 2 is fitted onto the surface of the strap 1, ensuring a tight fit between the urine storage bag 2 and the outer surface of the strap 1. Next, the elastic band 3 located on one side of the hinge rod 13 is flipped over to cover the upper and lower edges of the urine storage bag 2. Then, the first slot 31 at the end of the elastic band 3 is engaged with the hinge rod 13 on the other side to complete the closure and fixation of the elastic band 3. During this process, a detachable engagement relationship is formed between the first slot 31 and the hinge rod 13, facilitating the elastic band 3 to cover and limit the urine storage bag 2. The protrusion 32 at the end of the first slot 31 facilitates the pulling operation of the elastic band 3, and the compression protrusions 33 evenly distributed on the inner side of the first slot 31 exert a compression effect on the upper and lower edges of the urine storage bag 2, thereby improving the fixation stability of the urine storage bag 2 on the surface of the strap 1.

[0036] After the urine storage bag 2 is fixed, the drainage tube 21 is plugged into the top of the urine storage bag 2 and positioned outside the elastic band 3 to avoid the elastic band 3 compressing the drainage tube 21 and affecting the smooth drainage. At the same time, the normally closed drain tube 22 connected to the bottom of the urine storage bag 2 is kept closed so that the urine storage bag 2 can store liquid during wear and use.

[0037] Next, the guide tube 21 is inserted into the rubber seat 44 below the fixing block 4, so that the guide tube 21 passes through the second slot 45 opened on the surface of the rubber seat 44; during this process, the anti-slip protrusions 46 evenly arranged on the inner wall of the second slot 45 form a clamping and friction limiting effect on the guide tube 21, thereby reducing the possibility of the guide tube 21 falling off when it is pulled by external force.

[0038] Subsequently, the guide tube 21 continues to be laid along the guide path at the fixed block 4, so that the guide tube 21 passes through the lower guide shaft 41, the movable shaft 51 on the outer side of the slider 5 and the upper guide shaft 41 in sequence from bottom to top; in this process, the upper and lower guide shafts 41 and the movable shaft 51 together guide the direction of the guide tube 21, so that the guide tube 21 forms a controlled winding path above the strap 1. The horizontal groove 42 opened in the center of the surface of the fixed block 4 provides sliding space for the slider 5. The stop block 43 on one side of the groove 42 seals the open end of the groove 42. The end plate 411 set at the end of the guide shaft 41 is used to limit the movement of the guide tube 21 in the guide part, thereby ensuring the stability of the guide tube 21 in the guide process.

[0039] In normal wear, the spring 6 is horizontally positioned inside the slide groove 42, with one end of the spring 6 abutting against the slider 5, thereby continuously applying a pushing force to the slider 5 toward the stop block 43, keeping the slider 5 in the corresponding position under normal conditions; at this time, the guide tube 21 is in a taut state after being guided by the combined action of the rubber seat 44, the guide shaft 41 and the movable shaft 51, thereby reducing the occurrence of large-angle bending of the guide tube 21 during the user's walking or leg movements.

[0040] When the user experiences leg movements, clothing tugging, or other external forces during the wearing process, causing the drainage tube 21 to be pulled, the drainage tube 21 applies a pulling force to the movable shaft 51, which in turn drives the slider 5 to move along the slide groove 42. During the movement of the slider 5, the spring 6 is compressed, thereby buffering the pulling force on the drainage tube 21 and preventing the pulling force from being directly concentrated on the connection between the drainage tube 21 and the urine storage bag 2. After the external pulling force decreases or disappears, the spring 6 pushes the slider 5 to reset, and the drainage tube 21 returns to the taut state after being guided, so as to maintain the stability of the drainage connection and meet the needs of continuous wear and use.

[0041] The above description is merely a preferred embodiment of the present invention.
