Description

Technical Field

[0001] The invention relates to the technical field of stoma care, in particular to an abdominal band used after urinary tract stoma surgery. Background Art

[0002] Uroscopic ureterostomy refers to a surgical procedure in which the ureters or urethra are drained to the surface of the abdominal skin to form a urostomy due to bladder dysfunction, cystectomy or other urinary system diseases, thereby achieving urine discharge. This procedure is widely used in the treatment of patients with bladder cancer, severe bladder injury, neurogenic bladder, etc.

[0003] After searching, it was found that the prior art publication number is CN222854060U, which discloses a post-operative abdominal band for stoma patients, including a stoma plug, an adhesive, a sealing piece and a collecting bag; wherein, a circle of adsorbent is wrapped around the side wall of the stoma plug; the adhesive is arranged around the periphery of the inlet end of the stoma plug, and the side walls of the adhesive are relatively provided with a belt; the sealing piece is arranged inside the outlet end of the stoma plug; the collecting bag is detachably connected to the outlet end of the stoma plug; this solution can separate the stoma bag from the stoma when the patient is not defecating, thereby avoiding excrement from soaking the stoma, preventing stoma infection, and facilitating the patient's recovery.

[0004] Therefore, based on the above search and in combination with existing technologies, in the process of changing urine bags of existing products, traditional devices are usually unable to achieve temporary sealing or negative pressure adsorption. A large amount of urine may be discharged instantly due to the pressure difference in the body or the action of gravity. If the user or caregiver fails to connect a new urine bag in time, it is very easy to cause urine leakage and contaminate the bed sheets or the body. For this reason, the present application proposes a abdominal belt for use after urostomy surgery. Summary of the Invention

[0005] The object of the present invention is to provide a post-urostomy abdominal band to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an abdominal belt for use after urostomy surgery, comprising a waist belt, a urine bag being provided on the outside of the waist belt, a hole being provided on the outer surface of the waist belt, a support bracket being fixedly sleeved in the hole, and when the waist belt is worn on the body, the abdominal stoma is passed between the support brackets, a screw cap being fixedly connected to the outer surface of the urine bag, and the screw cap being detachably connected to the support bracket, and a urine leakage prevention device being provided inside the screw cap, for preventing urine from flowing out of the body during the process of changing the urine bag and preventing the area around the stoma from being contaminated.

[0007] As a further solution of the present invention, the inner end of the support bracket is sleeved with a shrinkable tube, the shrinkable tube is in contact with the inner wall of the support bracket, and a return spring is passed through the interior of the shrinkable tube.

[0008] As a further solution of the present invention, the shrink tube is rotatably connected to a passive ring at one end away from the support bracket. The passive ring is passed through the interior of the support bracket. The rotatable connection between the passive ring and the support bracket enables flexible guidance of the shrink tube to avoid pipeline distortion.

[0009] As a further solution of the present invention, a clamping ring is fixedly installed on the inner end of the shrink tube, and one end of the passive ring close to the clamping ring is fixedly connected to two hook plates, and the two hook plates are both arranged on the outer wall of the passive ring.

[0010] As a further solution of the present invention, a plurality of grooves are provided on the side of the passive ring away from the clamping ring. The grooves are arranged in a ring shape, and air guide holes are provided in the grooves. The air guide holes are connected to the internal cavity of the shrink tube. The groove structure improves the firmness of the fit between the passive ring and the external component to prevent loosening during use.

[0011] As a further solution of the present invention, the urine leakage prevention device includes a matching ring, which is fixedly installed inside the rotary cover. The end of the matching ring away from the urine bag is fixedly connected to a plurality of guide plates, which are arranged in a ring shape.

[0012] As a further solution of the present invention, a sealing bag is provided on the outer surface of the guide plate, and the length of the sealing bag is greater than the length of the guide plate, and the end of the sealing bag is fixedly connected to the matching ring.

[0013] As a further solution of the present invention, a sealing bag is fixedly installed on the inner end of the mating ring, and the sealing bag and the sealing bag are on the same axis. A plurality of protrusions are fixedly installed on the side of the mating ring close to the belt, and the protrusions correspond to the grooves on the outer surface of the passive ring.

[0014] As a further solution of the present invention, after the sealing bag is expanded, a circular hole is formed in the center thereof for urine to flow. The circular hole is in a closed state when the sealing bag is not expanded, and gradually opens as the sealing bag expands, thereby providing a smooth flow channel for urine. A sealing block is provided at the center of the sealing bag.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, a snap-fit ​​structure is provided between the mating ring and the passive ring. Through the communication between the air guide groove and the air guide hole, when the shrink tube is compressed, the sealing bag can be driven to automatically expand, so that the sealing bag forms a closed passage between the stoma and the outside world, thereby blocking urine leakage during the process of taking out the urine bag, avoiding overflow and leakage during the discharge process, and improving the overall sealing and safety of use; 2. When the present invention is used, the sealing bag is in a vertical state, and gravity can help prevent the sealing bag and the sealing block from continuing to contact each other, so that the residual urine in the sealing structure can flow back to the inside of the urine bag smoothly, avoiding discomfort or pollution caused by liquid retention, and ensuring the patency of the drainage system and the thoroughness of drainage; 3. When the present invention is used, the sealing bag gradually extends with the cooperation of the guide plate, and an independent closed chamber is formed inside it. The volume of the chamber increases with the extension process, thereby forming a negative pressure environment inside. The negative pressure chamber can actively attract the residual urine in the body to be discharged, effectively preventing the uncontrolled outflow of urine during the change of urine bags, preventing contamination of the skin or clothing around the stoma, and reducing the cleaning burden of the user.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-4 A abdominal belt for use after urostomy surgery includes a waist belt 1, a urine bag 2 is provided on the outside of the waist belt 1, the waist belt 1 is made of elastic fabric and is provided with Velcro for adjusting the diameter of the waist belt 1 to adapt to people with different waist circumferences, the outer surface of the waist belt 1 is provided with holes, a support bracket 101 is fixedly sleeved in the holes, and the support bracket 101 is circular. After the waist belt 1 is worn on the body, the abdominal stoma part is passed between the support brackets 101, the outer surface of the urine bag 2 is fixedly connected to the screw cover 201, and the screw cover 201 is detachably connected to the support bracket 101, and the inside of the screw cover 201 is also provided with a urine leakage prevention device for preventing urine from flowing out of the body during the process of changing the urine bag 2 and preventing the area around the stoma from being contaminated; Specifically, when cleaning is required, the user can remove the urine bag 2 from the belt 1, and after cleaning, can install it back on the belt 1 to continue using it. The end of the urine bag 2 away from the belt 1 is provided with a liquid outlet tube, and the liquid outlet tube is equipped with a control valve. Before going to sleep, the user can connect the urinary catheter to the liquid outlet tube, so that the urine discharged at night directly enters the urine bag 2 through the urinary catheter and is smoothly discharged through the liquid outlet tube, reducing the frequency of changing the urine bag 2 or handling urine at night.

[0020] like Figure 3 、 Figure 4 As shown, the inner end of the support bracket 101 is sleeved with a shrink tube 102, which fits the inner wall of the support bracket 101, and the diameter of the shrink tube 102 is larger than the volume of the stoma, and the shrink tube 102 is made of medical soft silicone material, which is foldable and environmentally friendly and hygienic, and a return spring 104 is passed through the interior of the shrink tube 102. When the shrink tube 102 is compressed, it can return to its initial state under the elastic force of the return spring 104, and the end of the shrink tube 102 away from the support bracket 101 is rotatably connected to a passive ring 105 through a sealed bearing, and the passive ring 105 is passed through the interior of the support bracket 101, and its outer surface is in contact with the inner wall of the support bracket 101; Specifically, one end of the shrink tube 102 away from the passive ring 105 is fixedly connected to the inner wall of the support bracket 101, and the inner end of the shrink tube 102 is fixedly installed with a snap ring 103 by heat welding. The diameter of the snap ring 103 is larger than the diameter of the return spring 104. The end of the passive ring 105 close to the snap ring 103 is fixedly welded with two hook plates 107. The two hook plates 107 are both arranged on the outer wall of the passive ring 105 and are respectively located at two relative positions on the passive ring 105 where the distance between each other is the largest. The edges corresponding to the snap ring 103 and the two hook plates 107 are set to a horizontal structure (see Figure 4), so that when the hook plate 107 approaches the snap ring 103, it can smoothly pass over the horizontal edge and enter the internal space of the snap ring 103. Then, as the passive ring 105 rotates, the hook plate 107 gradually transitions from the horizontal edge of the snap ring 103 to the arcuate edge of the snap ring 103, thereby completing the stable connection of the hook plate 107 to the snap ring 103, ensuring that the device has a good locking effect during use; A plurality of grooves are formed on one side of the passive ring 105 away from the clamping ring 103 . The grooves are arranged in a ring shape, and each groove has an air guide hole 108 formed therein. The air guide hole 108 is communicated with the inner chamber of the shrink tube 102 .

[0021] Example 2: Please refer to Figure 2 、 Figure 5-Figure 9 A post-operative abdominal band for urostomy surgery, based on Example 1, includes a urine leakage prevention device comprising a mating ring 202, which is fixedly mounted inside a screw cap 201. A plurality of guide plates 207 are fixedly connected to one end of the mating ring 202 away from the urine bag 2. The guide plates 207 are arc-shaped and arranged in a ring. Specifically, the sides of the guide plates 207 away from the mating ring 202 are rounded. The guide plates 207 are made of soft silicone material, which has good fit and cushioning properties. When the urine bag 2 is mounted on the waist belt 1, the rounded edge of the guide plate 207 first contacts the outer surface of the stoma. Under the support of the stoma, the end of the guide plate 207 away from the matching ring 202 opens, thereby forming a covering effect that adapts to the contour of the stoma. The outer surface of the guide plate 207 is covered with a sealing bag 206, and the length of the sealing bag 206 is greater than the length of the guide plate 207. The sealing bag 206 is a ring-shaped structure. Therefore, after the sealing bag 206 is wrapped around the outer surface of the guide plate 207, there will be an excess part on the side close to the matching ring 202. In order to ensure a tight covering and a neat structure, the excess length needs to be folded inwards so that the sealing bag 206 fits more snugly on the guide plate 207. The end of the sealing bag 206 is fixedly connected to the matching ring 202. Specifically, such as Figure 9As shown, the sealing bag 206 is also made of ultra-thin soft silicone material, which has good softness and certain elasticity. Its outer surface is frosted, which can effectively prevent sliding and improve stability when worn. The outer surface of the guide plate 207 is smooth, and the friction coefficient between the sealing bag 206 and the guide plate 207 is small. Under the support and fitting action of the guide plate 207, the sealing bag 206 can fit tightly to the outer surface of the stoma to form a covering structure, so that the urine discharged from the stoma can only flow through the internal channel of the sealing bag 206, thereby effectively avoiding turbulence, leakage or contamination of the surrounding skin during the discharge process of urine, further improving the hygiene and sealing effect of use. It is worth noting that the annular structure composed of multiple guide plates 207 can be replaced with different specifications according to actual needs to adapt to users of different body shapes or stoma sizes.

[0022] A sealing bag 203 is fixedly mounted on the inner end of the mating ring 202. The sealing bag 203 and the sealing bag 206 are coaxial. A plurality of protrusions are fixedly mounted on the side of the mating ring 202 close to the waist belt 1. The protrusions correspond to the slots on the outer surface of the passive ring 105. Specifically, the outer surfaces of the protrusions are wrapped with sealing rubber pads, so that when the protrusions are inserted into the slots, the sealing performance is further improved. A plurality of air guide grooves 208 are provided inside the mating ring 202. The input end of the air guide groove 208 corresponds to the air guide hole 108, and the output end thereof is connected to the interior of the sealing bag 203. When the shrink tube 102 is compressed, the air squeezed inside it enters the interior of the sealing bag 203 along the air guide groove 208, causing the sealing bag 203 to expand.

[0023] like Figure 6-Figure 9 As shown, after the sealing bag 203 is expanded, a circular hole is formed in the center thereof for urine to flow. The circular hole is in a closed state when the sealing bag 203 is not expanded, and gradually opens as the sealing bag 203 expands, thereby providing a smooth flow channel for urine (as shown in FIG. Figure 8 shown); A sealing block 204 is provided at the center of the sealing bladder 203. The sealing block 204 has a "T"-shaped structure and is used to close the urine outlet when the sealing bladder 203 is not expanded. When the sealing bladder 203 is in an expanded state, its inner edge is located below the "T"-shaped sealing block 204, forming an annular structure surrounding the sealing block 204. When the sealing bladder 203 is not expanded, due to its own volume limitation, the edge cannot pass over the top of the "T"-shaped structure. At the same time, a sufficient gap is reserved between the expanded sealing bladder 203 and the sealing block 204 to allow urine to flow smoothly through the channel, thereby achieving the drainage function. In addition, the sealing block 204 is connected to the matching ring 202 via a plurality of pulling lines, and the pulling lines ensure that the sealing block 204 is always located at the center point of the sealing capsule 203 .

[0024] like Figure 2 、 Figure 3 、 Figure 6 As shown, two latches 205 are fixedly welded on the outer surface of the rotary cover 201, and the two latches 205 are respectively arranged at both ends of the diameter of the rotary cover 201. Two locking holes 106 are provided on the outer surface of the support bracket 101, and the locking holes 106 correspond to the latches 205. Specifically, the locking hole 106 has a water drop-shaped structure. After the two latches 205 are inserted into the interior of the locking hole 106, they are rotated a certain angle along the water drop-shaped contour so that the latches 205 slide in from the wider part and are finally positioned at the narrower part, thereby achieving a stable locking of the urine bag 2.

[0025] The working principle of the present invention is: By connecting the screw cap 201 with the support bracket 101, the urine bag 2 is hung on the waist belt 1. During this process, the guide plate 207 is wrapped around the outer surface of the stoma, and then the protrusion on the outer surface of the matching ring 202 is inserted into the groove on the outer surface of the passive ring 105. At this time, the air guide groove 208 is connected with the air guide hole 108, and the shrink tube 102 is compressed at the same time. The air inside the shrink tube 102 enters the interior of the sealing bag 203, and the sealing bag 203 begins to expand. After the two latches 205 are inserted into the interior of the lock hole 106, they are rotated a certain angle along the teardrop-shaped contour so that the latches 205 slide from the wider part and finally locate at the narrower part, thereby achieving a stable locking of the urine bag 2. At the same time, the hook plate 107 gradually transitions from the horizontal edge of the snap ring 103 to the arcuate edge of the snap ring 103, thereby completing the connection of the hook plate 107 to the snap ring 103. When replacing the urine bag 2, the cover 201 is rotated in the opposite direction so that the hook plate 107 can be separated from the clamp ring 103, and the urine bag 2 is slowly removed. At this time, the sealing bag 206 is wrapped around the outer surface of the stoma under the action of its own elastic force, and has a certain friction with the outer surface of the stoma. As the cover 201 gradually moves away from the support 101, the folded part of the sealing bag 206 is continuously stretched (such as Figure 9 As shown), while the air inside the sealing bag 203 is lost, its inner edge is wrapped around the outer surface of the sealing block 204 (as shown Figure 8 As shown), a separate chamber is formed inside the sealing bag 206. As the sealing bag 206 is extended, the chamber becomes larger, thereby forming a negative pressure chamber. At this time, the urine remaining in the body is extracted under the negative pressure, thereby preventing the residual urine in the body from flowing out uncontrollably during the process of changing the urine bag 2, thereby causing a burden to the user; Finally, the sealing bag 206 is completely separated from the stoma. The end of the sealing bag 206 is pinched by hand and kept in a vertical position. The urine remaining in the sealing bag 206 opens the connection between the sealing capsule 203 and the sealing block 204 under the action of gravity and finally flows into the urine bag 2. After the cleaned urine bag 2 is dried, the sealing bag 206 is again placed on the outer surface of the guide plate 207 so that the urine bag 2 can be reused.

[0026] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
