Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a two-piece enterostomy flushing device. Background Art

[0002] As a frequently performed, key surgical technique, intestinal stoma surgery is of undeniable importance. It serves not only as a temporary solution for acute abdominal surgery but also as a permanent, curative treatment for certain conditions. This type of surgery has not only saved countless lives but also offered hope for restoring quality of life. Globally, intestinal stoma surgery has gained widespread recognition and application, becoming an integral part of the medical field.

[0003] However, while ostomy surgery is a lifeline, it also places both physical and mental strain on patients. In particular, the fundamental change in bowel movements, forcing patients to rely on a stoma bag for a long time, not only alters their appearance but also triggers a deep sense of depression and a false sense of aging. This change often alienates patients from family and friends, and can even lead to serious psychological disorders such as depression, severely eroding their quality of life.

[0004] To alleviate this dilemma, postoperative stoma care is crucial. Unfortunately, the one-piece stoma bags currently available on the market often offer limited functionality and fail to meet patients' urgent needs for real-time stoma observation and effective care. Frequently removing the bag to inspect the stoma not only increases pain and inconvenience for patients, but also increases the risk of infection, making the care process more complex and tedious.

[0005] In addition, patients with colostomy need to regularly perform nursing measures such as flushing and cleaning of the stoma after surgery, and the stoma also needs to be monitored daily. However, frequent disassembly of the adhesive-fixed ostomy bag not only easily leads to damage to the adhesive components, but also the operation process is cumbersome, causing inconvenience to the patient. The current ostomy bag design lacks additional observation windows, which makes the colostomy in a humid, closed environment for a long time, increasing the risk of infection and inflammation. If the air circulation is improved in a short period of time by disassembling the ostomy bag, the dirt discharged from the colostomy cannot be handled in time, which will bring inconvenience to the patient's life. Therefore, how to improve the structure of the ostomy bag so that the colostomy can be dried and ventilated without frequent disassembly, while facilitating the spraying operation, remains a problem that needs to be solved urgently.

[0006] For example, CN213346261U discloses an ostomy bag, comprising an ostomy bag body and an anti-stagnation structure, the ostomy bag body comprises an ostomy bag front diaphragm and an ostomy bag rear diaphragm connected to each other, the ostomy bag front diaphragm and the ostomy bag rear diaphragm jointly enclose a liquid collecting cavity, an upper part of the ostomy bag rear diaphragm is provided with a drainage hole communicating with the liquid collecting cavity, the drainage hole is connected to a stoma of a patient to guide the discharge of the patient into the liquid collecting cavity, and a lower part of the ostomy bag body is provided with a liquid outlet communicating with the liquid collecting cavity. The anti-stagnation structure is arranged in the liquid collecting cavity to prevent the ostomy bag front diaphragm and the ostomy bag rear diaphragm from being adhered to each other, so that the liquid entering the liquid collecting cavity from the drainage hole can flow out from the liquid outlet. The ostomy bag is a typical one-piece ostomy bag, which cannot provide an opening for the stoma and ventilation at any time.

[0007] For another example, CN213641505U discloses an ostomy bag with a flushing device, comprising an ostomy bag and a bottom plate, the bottom plate is fixedly connected to one side of the ostomy bag, and a flushing device is fixedly connected to the other side of the ostomy bag. The flushing device comprises a flushing pipe and a flushing cylinder, one end of the flushing cylinder is an open structure, the other end of the flushing cylinder is a closed structure, one end of the flushing cylinder is fixedly connected to the ostomy bag, and one end of the flushing pipe penetrates through the sealing end of the flushing cylinder and communicates with the inside of the flushing cylinder. The bottom of the ostomy bag is provided with a discharge port, the bottom of the discharge port is provided with a discharge connector, the discharge connector comprises a first connector, a second connector and a plug, the first connector is inserted into the discharge port, the second connector is inserted into the first connector, and the plug is buckled with the second connector. The flushing device on the ostomy bag cannot be detached from the ostomy bag, so it cannot provide a ventilation environment for the stoma, and therefore it is also a one-piece ostomy bag.

[0008] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, a large number of literatures and patents have been studied by the applicant when the utility model is made, but all the details and contents cannot be listed in detail due to the limitation of the space, however, this does not mean that the utility model does not have the characteristics of the prior art, on the contrary, the utility model has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. Content of the utility model

[0009] The one-piece ostomy bag on the current market has relatively single function, and it is difficult to meet the urgent needs of patients for real-time observation and effective nursing of intestinal stoma. Although some ostomy bags are made of transparent material, medical staff still cannot directly observe the condition of intestinal stoma due to the shielding of dirt. In order to carry out necessary monitoring, nursing staff generally need to frequently detach the bottom plate of the ostomy bag, which not only increases the pain and inconvenience of the patient, but also increases the risk of infection. In addition, the detaching process is complicated, which further complicates the nursing work. Therefore, it is urgent to improve the design of the ostomy bag, so that it can realize effective observation and nursing of intestinal stoma without frequent detachment, and improve the quality of life of patients.

[0010] In view of the deficiencies of the prior art, the utility model provides a two-piece intestinal stoma flushing device, including stoma bag main part and flushing part, flat bottom dish or convex bottom dish is connected fixedly with first opening of first side surface of stoma bag main part, flushing part is set up in the second opening of the second side surface of stoma bag main part with detachable, wherein, flushing part includes each other detachable opening fixing piece and cover, opening fixing piece sets up in the rim of second opening to define the shape of second opening, cover is provided with the shower flow guide that is detachable with cover and is used for flushing intestinal stoma, shower flow guide communicates with the liquid inlet hole on the cover, in the flushing case of flushing liquid under the condition of pressure into liquid inlet hole, shower flow guide guides flushing liquid from multiple directions to flush intestinal stoma, or, in the non-flushing case, shower flow guide is separated with cover, cover is in the open state and provides non-closed environment for intestinal stoma, or, cover is in the closed state and provides sanitary isolation environment for intestinal stoma.

[0011] The utility model adds the detachable second opening on the second side surface of stoma bag. Different from the traditional closed observation bag, the second opening makes medical staff and patients can directly observe the condition of intestinal stoma without disassembling the stoma bag.

[0012] According to one preferred embodiment, the second side surface of the stoma bag main part is provided with an exhaust hole, the exhaust hole is provided with an exhaust valve and a plug body, and an odor eliminating assembly is arranged on the wall of the exhaust hole to prevent odor from overflowing from the exhaust hole. The odor eliminating assembly maximally reduces the diffusion of odor, maintains the surrounding environment, and improves the comfort and satisfaction of patients during use.

[0013] According to one preferred embodiment, in the case that the stoma bag main part is in a use state, the height of the flushing part is not less than the height of the first opening, and the overlapping area of the second opening of the flushing part with the first opening is not less than 50%, so that the flushing area of the flushing liquid in the shower flow guide can cover the intestinal stoma. In this way, the intestinal stoma can be thoroughly cleaned, avoiding leaving a cleaning dead angle.

[0014] According to one preferred embodiment, the overlapping area of the second opening of the flushing part with the first opening is not less than 80%, so that the flushing center of the shower flow guide corresponds to the position of the intestinal stoma, thereby guiding the flushing liquid to flush the intestinal stoma from multiple directions. In this way, the intestinal stoma can be thoroughly cleaned.

[0015] According to a preferred embodiment, the spray guide has an arc-shaped curved surface, and a plurality of side holes and a plurality of end face holes are arranged on the curved surface. In the case of flushing liquid entering the liquid inlet hole in a pressure manner, the side holes and the end face holes guide the flushing liquid to spray towards the enterostomy in a manner that the flow rate and / or the flushing angle are different. Such a design ensures that the flushing liquid can be quickly and uniformly sprayed out through each hole, thereby achieving comprehensive coverage and effective flushing of the enterostomy and the surrounding area, improving the flushing efficiency and ensuring the uniformity and consistency of the flushing.

[0016] According to a preferred embodiment, the opening fixing member is provided with a first clamping structure, and the cover is provided with a second clamping structure. The structures of the first clamping structure and the second clamping structure are arranged in a manner that they can be clamped to each other. In this way, the cover can seal the second opening.

[0017] According to a preferred embodiment, the side edge of the second side of the ostomy bag body is provided with a scale line. In the case of flushing, when the liquid outlet of the ostomy bag body is closed, the scale line shows the capacity of the flushing liquid. The transparent window indication mark allows patients and medical staff to intuitively understand the capacity of the flushing liquid and the flushing progress.

[0018] According to a preferred embodiment, the wall of the exhaust hole is provided with a cavity, and odor adsorption particles are arranged in the cavity to form an odor elimination assembly. The odor adsorption particles are, for example, activated carbon. The activated carbon is specially designed to effectively adsorb and remove the odor discharged from the inside of the ostomy bag body due to its excellent adsorption performance. The surrounding configuration ensures that the activated carbon layer can fully contact and treat the gas flowing through the exhaust hole, thereby maximizing the odor removal efficiency.

[0019] According to a preferred embodiment, the cover is rotatably connected to the opening fixing member by a detachable connecting piece, so that the cover installed with the spray guide can be replaced with the cover without the spray guide. In this way, the patient can detach the spray guide and the cover, providing the patient with a more flexible replacement method.

[0020] According to a preferred embodiment, in the case that the ostomy bag body is in use, the liquid outlet angle of the side hole and / or the end face hole with a height lower than the height of the axis of the spray guide is arranged in a manner that directs the flushing liquid to tilt towards the enterostomy, so that the position vertically below the enterostomy is cleaned. Due to the influence of gravity, the pressure of the flushing liquid at the lowest position of the enterostomy is insufficient, which makes it difficult to clean the lowest position of the enterostomy. The present utility model is designed in this way to avoid the lowest position of the enterostomy from becoming a cleaning dead angle. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0033] The current market one-piece ostomy bag is relatively single in function, which is difficult to effectively meet the urgent needs of patients for real-time observation and care of intestinal stoma. Although some ostomy bags use transparent materials, due to the obstruction of dirt, medical staff still cannot directly grasp the actual state of the intestinal stoma, which leads to the inability to intervene and care in time.

[0034] When necessary monitoring is performed, the caregiver has to frequently disassemble the bottom plate of the ostomy bag, which not only brings additional pain and inconvenience to the patient, but also increases the risk of infection. This repeated disassembly not only causes physical and psychological burden to the patient, but also makes the nursing work more complex. The caregiver needs additional time and effort to ensure the safety and effectiveness of the operation each time.

[0035] Therefore, it is particularly urgent to effectively improve the design of the ostomy bag. The ideal solution should be able to achieve effective observation and care of the intestinal stoma without frequent disassembly. This not only greatly improves the quality of life of patients, but also reduces the workload of medical staff, optimizes the overall care process, and significantly improves the physical health and life satisfaction of patients.

[0036] In view of the deficiencies of the prior art, the utility model provides a two-piece intestinal stoma flushing device, as shown in Figures 1 to 10 The two-piece intestinal stoma flushing device comprises an ostomy bag body 100 and a flushing part 300.

[0037] As shown in Figures 1 to 5As shown, the ostomy pouch body 100 is divided into two types according to the difference in use, i.e. the first type of ostomy pouch and the second type of ostomy pouch. The first type of ostomy pouch is suitable for urinary intestinal stoma, and in order to facilitate the discharge of liquid, the liquid outlet 140 of the ostomy pouch body 100 is provided with a smaller liquid outlet pipe and a corresponding plug. The second type of ostomy pouch is suitable for defecating intestinal stoma, and in order to facilitate the discharge of feces, the defecation outlet 150 of the ostomy pouch body 100 is provided with a larger diameter outlet to cope with a larger amount of defecation. The defecation outlet 150 is fixed after being curled using the curling fixing member 130. In order to facilitate the intuitive distinction between the two types of ostomy pouches, Figures 1 to 5 Both show the structure of the same observation angle of the two types of ostomy pouch bodies 100.

[0038] The ostomy pouch body 100 in the prior art is provided separately with a base plate. During use by the patient, the phenomenon often occurs that the connection between the base plate and the ostomy pouch body 100 of the first type of ostomy pouch leaks. The connection between the base plate and the ostomy pouch body 100 of the second type of ostomy pouch also leaks. Although the defecation material is solid or semi-solid, if the interface between the base plate and the ostomy pouch body 100 is problematic, and the patient encounters a large pressure during defecation (for example, forced defecation due to constipation), the liquid part or smaller solid part in the feces may leak out from the interface, causing the base plate and the ostomy pouch body 100 of the second type of ostomy pouch to leak.

[0039] Based on the defects of the prior art, the connection between the base plate and the ostomy pouch body 100 is improved in the present application, i.e. the base plate and the ostomy pouch body 100 are integrally provided, or the base plate and the ostomy pouch body 100 are relatively fixedly connected. The fixed connection mode is, for example, a fixed mode such as adhesion, thermoplastic packaging, etc.

[0040] The advantage of such a setting is that there is no separate interface between the first type of ostomy pouch and the second type of ostomy pouch and the base plate, and the overall sealing is stronger. Such a setting also simplifies the operation process, and the patient does not need to worry about whether the connection is firm, and only needs to replace a complete set of ostomy pouches, reducing complexity. The integrally provided or fixedly connected mode of the base plate and the ostomy pouch body 100 also reduces the risk of wear and loosening at the connection, and is safer and more reliable for long-term use.

[0041] Preferably, the base plate on the ostomy pouch body 100 of the present application includes a flat base plate 200 and a convex base plate 400. As Figure 2 and Figure 4As shown, the flat base plate 200 is a disc structure with a central hole for direct attachment to the skin. The flat base plate 200 is generally soft and has good adhesion to ensure a tight fit to the skin and prevent any leakage. The flat base plate 200 is generally provided with adhesive edges to help the flat base plate 200 firmly fixed around the skin, and can be provided with pre-cut or self-cutting design to adapt to different sizes of stoma. The flat base plate 200 is particularly suitable for users with relatively flat skin surface around the stoma, as its flat design can better fit and seal in the case of flat skin. In addition, the flat base plate 200 is suitable for cases where the stoma location is not easily subjected to external pressure or extrusion, ensuring that the flat base plate 200 can be stably attached to the skin.

[0042] The convex base plate 400 has a convex surface with a certain curvature, which can better fit the uneven skin surface. As shown in Figure 3 、 Figure 5 and Figure 6 , the convex base plate 400 generally has a central convex part, which gradually flattens around to form a smooth transition area. Further, the central convex part of the convex base plate 400 protrudes from the surface of the first side of the pouch body 100. The material of the convex base plate 400 is also soft and has good adhesion, but is designed to better adapt to raised or depressed skin areas, and can also be provided with a pre-cut or self-cutting design to adapt to different sizes of stoma. The convex base plate 400 is specially designed for patients with uneven skin surface around the stoma, with depressions, protrusions or wrinkles, and its curvature design can fit these complex skin surfaces, providing better sealing and fixation. The convex base plate 400 is suitable for cases where the stoma location can be subjected to external pressure or extrusion, providing better cushioning and protection.

[0043] As shown in Figures 1 to 6 , the edge profile of the pouch body 100 is arc-shaped, and in the direction pointing to the liquid outlet 140 or the defecation port 150, the width of the pouch body 100 is arranged in a gradually decreasing manner.

[0044] As shown in Figures 1 to 6 , the first side of the pouch body 100 is provided with a first opening 210 for the intestinal stoma to enter the pouch body 100. The second side of the pouch body 100 is provided with a second opening 310 for observing the intestinal stoma and flushing the intestinal stoma. This design aims to achieve a convenient installation and replacement process, so that direct observation of the intestinal stoma, maintenance and treatment of the intestinal stoma, and ventilation and spray cleaning of the intestinal stoma can be achieved without disassembling the pouch.

[0045] As shown in Figures 4 to 6As shown, the flat flange 200 or the convex flange 400 (collectively referred to as the flange) is arranged at the first opening 210 of the first side of the ostomy bag body 100. The adhesive structure of the flange is described by taking the flat flange 200 as an example. The flat flange 200 is provided with a first adhesive 220 and a second adhesive 230. In the factory state, the flat flange 200 further includes the second adhesive 230. In Figure 2 the second adhesive 230 covers the surface of the first adhesive 220 due to the display structure. The first adhesive 220 and the second adhesive 230 are adhesively fixed to each other. One side of the second adhesive 230 is provided with skin-adhesive glue and a release paper. When the release paper is removed, the second adhesive 230 is adhesively fixed to the skin around the stoma. The first adhesive 220 and the second adhesive 230 are adhesively fixed to each other to fix the ostomy bag body 100. The adhesive structure of the convex flange 400 is similarly arranged, and is not repeated here.

[0046] Specifically, the size of the through hole of the flat flange 200 and the convex flange 400 needs to be accurately measured and cut to ensure that it is slightly larger than the current stoma size, thereby providing reliable sealing effect and skin protection. As shown, Figure 6 the visible surface of the flat flange 200 and the convex flange 400 is provided with a plurality of aperture scales to facilitate the patient to cut the through hole. Preferably, the size of the through hole of the second opening 310 is set to be larger than the size of the first opening 210. This design not only facilitates the smooth performance of the irrigation operation and ensures that the second opening 310 can completely observe the stoma and the surrounding skin of the patient, but also takes into account the additional space that may be needed during the irrigation process, thereby avoiding problems such as poor irrigation or liquid backflow due to the second opening 310 being too small. Through such a design, the two-piece intestinal stoma irrigation device can more flexibly meet the individual needs of patients and ensure the smoothness and safety of the irrigation process.

[0047] As shown, Figures 1 to 6 the irrigation part 300 is arranged at the second opening 310 of the second side of the ostomy bag body 100 in a detachable manner. This design allows the irrigation and drying ventilation of the stoma to be achieved without removing the entire ostomy bag body 100, thereby greatly simplifying the irrigation steps and reducing the operational burden of the patient. This design not only improves the irrigation efficiency, but also ensures the hygiene and safety during the irrigation process and reduces the risk of cross infection.

[0048] As shown, Figures 1 to 10As shown, the flushing portion 300 includes an opening fixing member 320 and a cover 334 that are detachable from each other. The opening fixing member 320 is arranged at the edge of the second opening 310 to define the shape of the second opening 310. The opening fixing member 320 is, for example, an annular plastic component. A first fixing structure 321 is provided on the opening fixing member 320. A second fixing structure 333 is provided on the cover 334. The structures of the first fixing structure 321 and the second fixing structure 333 are arranged in a manner that they can be snap-fitted to each other. In this manner, the cover 334 can seal the second opening 310. Preferably, as Figure 1 As shown, a locking member 337 is also provided on the outside of the open fixing member 320. The locking member 337 is an annular structure with a fracture, and a male and female snap that can be fixed are provided at both ends of the locking member 337. For example, the male snap is provided with at least one raised structure protruding from the surface of the main body. The raised structure can be of any shape. The female snap sheet is provided with an open cavity, and one side of the cavity is a hollow structure. The thickness of the cavity matches the thickness of the male snap sheet. When the male snap moves into the cavity of the female snap, the raised structure is stuck by the edge of the hollow structure, making it impossible for the male snap to move out of the cavity, thereby achieving relative fixation of the male and female snaps. When the male and female snaps are relatively fixed, the gap between the first fixing structure 321 and the second fixing structure 333 is further compressed and reduced, thereby achieving the effect of locking the cover 334.

[0049] For example, the first securing structure 321 is provided on the outer edge of the opening fixture 320, such as a circular protruding edge. The second securing structure 333 is provided on the inner edge of the cover 334, such as a concave structure that can engage the protruding edge. When the opening fixture 320 and the cover 334 are engaged, the concave structure engages the protruding edge to achieve relative closure between the opening fixture 320 and the cover 334. Preferably, a sealing ring can also be provided within the cover 334 to prevent leakage. Through the tight fit and locking mechanism between the first securing structure 321 and the second securing structure 333, the irrigating portion 300 is securely connected to the ostomy bag body 100, achieving a detachable connection. This design not only simplifies the installation and removal process, improving operational convenience, but also ensures the stability of the connection, preventing liquid leakage or other adverse consequences caused by loose connections during the irrigating process. This design also facilitates regular cleaning and maintenance of the irrigating assembly by the patient, extending the service life of the device.

[0050] like Figures 1 to 9 As shown, the edge of the cover 334 is provided with an extension edge 332 for pinching and moving the cover 334 by hand. The extension edge 332 is preferably a protruding structure protruding from the outer edge of the cover 334, preferably a sheet-like protruding structure.

[0051] According to a preferred embodiment, Figures 1 to 9As shown, the cover 334 is rotatably connected to the opening fixture 320 via a detachable connector 322, such as a bolt connection or a short shaft connection, allowing the cover 334 with the spray deflector 330 installed to be replaced with the cover 334 without the spray deflector 330. The detachable connector 322 can also be a flexible belt. This design allows the patient to remove both the spray deflector 330 and the cover 334, providing patients with more flexible replacement options.

[0052] Or, as Figures 7 to 9 As shown, the spray deflector 330 on the cover 334 is detachably mounted on the inner side of the cover 334, so that the patient does not need to replace the cover 334, and only needs to remove or install the spray deflector 330 to achieve different uses. When spray irrigation of the stoma is not needed, the spray deflector 330 can be removed from the cover 334.

[0053] like Figures 1 to 9 As shown, especially Figure 8 As shown, the cover 334 is provided with a spray deflector 330 that is detachably mounted on the cover 334 and is used to flush the enterostomy, ensuring that the spray deflector 330 can be securely mounted on the inner side of the cover 334. For example, the spray deflector 330 is connected to the cover 334 via a threaded structure or a snap-fit ​​structure.

[0054] like Figures 1 to 9 As shown, a liquid inlet hole 331 is provided on the cover 334. Figures 1 to 9 As shown, the liquid inlet 331 is arranged to protrude from the outer surface of the cover 334, making it easy to engage with the liquid outlet of medical instruments such as syringes. The liquid inlet 331 is designed specifically for the smooth flow of flushing liquid, and can efficiently guide the flushing liquid into the flushing area to achieve a comprehensive and thorough flushing effect on the stoma and its surrounding area. The size of the liquid inlet 331 is designed according to the size of the liquid outlet of a common syringe, which reduces the difficulty of connecting the liquid inlet 331 to the syringe. The design of the liquid inlet 331 fully considers factors such as the pressure, flow rate and direction of the flushing liquid to ensure that the flushing process is both effective and safe, avoiding discomfort or harm to the patient.

[0055] Preferably, if Figures 1 to 3As shown, the liquid inlet hole 331 is designed as a detachable structure, which can realize stable and flexible connection with the syringe. In actual operation, the patient can dock the syringe with the liquid inlet hole 331, and by pushing the push rod of the syringe, the flushing liquid stored in the syringe can be smoothly and accurately injected into the inside of the spray guide 330. This design not only simplifies the flushing process and improves the convenience of operation, but also ensures that the flushing liquid can smoothly and efficiently reach the flushing area, achieving effective flushing of the enterostomy and the surrounding area. At the same time, the detachable connection mode also facilitates the patient to replace different specifications or capacities of the syringe according to actual needs, as well as to clean and maintain the syringe and the flushing assembly.

[0056] The spray guide 330 is in communication with the liquid inlet hole 331 on the cover 334. When the syringe injects the flushing liquid with a certain pressure through the liquid inlet hole 331, under the flushing condition that the flushing liquid enters the liquid inlet hole 331 in a pressure manner, the spray guide 330 guides the flushing liquid to flush the enterostomy from multiple directions.

[0057] In the non-flushing condition, as shown in FIG. 4, the spray guide 330 is separated from the cover 334, and the cover 334 is in an open state to provide a non-closed environment for the enterostomy, or the cover 334 is in a closed state to provide a hygienic isolation environment for the enterostomy. Figure 9 According to a preferred embodiment, as shown in FIGS. 5 and 6, the spray guide 330 has an arc-shaped curved surface or a bent surface, and a plurality of side holes 335 and a plurality of end face holes 336 are arranged on the curved surface or the bent surface in a spaced manner. The precise layout of the holes on the outer surface of the spray guide 330 ensures that the flushing liquid can efficiently and stably enter the flushing area. The design of the plurality of side holes 335 and the plurality of end face holes 336 not only considers the flow rate and pressure requirements of the flushing liquid, but also takes into account the optimization of the flushing angle and coverage range, so as to realize comprehensive and uniform flushing of the stoma and the surrounding area, thereby improving the flushing effect and reducing the discomfort of the patient.

[0059] ​​​Preferably, the spray guide 330 can also be provided with a plurality of channels connected with the plurality of side holes 335 and the plurality of end face holes 336, respectively. These channels, which are connected with the side holes 335 and the end face holes 336, can be arranged independently or staggered to ensure uniform distribution of the flushing liquid to each hole. The layout can be designed in a radial, grid or other form according to specific needs. Different diameters of the channels are used to achieve different flushing pressures of the flushing liquid, so that the plurality of side holes 335 and the plurality of end face holes 336 have different flushing pressures on the enterostomy. In terms of channel diameter and size, the diameter of the channel is designed according to the required jet pressure and flow rate. A larger diameter provides lower flow resistance and higher flow rate, while a smaller diameter provides higher pressure. Some channels can also be designed in a tapered shape to increase the liquid flow rate and achieve different jetting effects. The hole inclination and liquid outlet direction of the plurality of side holes 335 and the plurality of end face holes 336 can also be designed flexibly, so that the liquid outlet angle and flow rate of the plurality of side holes 335 and the plurality of end face holes 336 are different. For example, the side holes 335 are designed at different inclination angles (e.g. 30 degrees, 45 degrees, 60 degrees) to form a multi-angle, multi-directional jetting mode. The end face holes 336 are designed to be vertically downward and at different angles to ensure that the liquid can cover the complex surface and internal structure of the part.

[0060] The channel material should be corrosion and pressure resistant, such as stainless steel or engineering plastic, and the inner wall should be smooth to reduce flow resistance and ensure smooth liquid flow. In terms of channel distribution and connection, the channels should be evenly distributed to ensure consistent pressure and flow rate of each hole, and connected with the holes through precise connection structure to avoid leakage and blockage during flow.

[0061] Preferably, a mechanical central distributor can be provided at the liquid inlet hole 331 to distribute the flushing liquid to each channel, or an annular channel can be provided to distribute a plurality of branch connection holes. The mechanical central distributor distributes the incoming flushing liquid to each channel through a simple mechanical structure, usually relying on the pressure and flow path of the liquid to distribute, without the need for power support.

[0062] Therefore, in the case of flushing where the flushing liquid enters the liquid inlet hole 331 under pressure, the side holes 335 and the end face holes 336 guide the flushing liquid to spray towards the enterostomy in a manner that the flow rate and / or the flushing angle are different. Such design ensures that the flushing liquid can be quickly and uniformly sprayed out through each hole, thereby achieving comprehensive coverage and effective flushing of the enterostomy and its surrounding area, improving the flushing efficiency and ensuring the consistency of the flushing.

[0063] Due to the influence of gravity, the pressure of the irrigation liquid at the lowest position of the stoma is insufficient, so that the lowest position of the stoma is not easy to be cleaned. According to a preferred embodiment, when the stoma bag body 100 is in a use state, the liquid outlet angle of the side hole 335 and / or the end face hole 336 which is lower than the height of the axis of the spray guide 330 is arranged in a way that the irrigation liquid is inclined to spray out of the stoma, so that the vertical lower part of the stoma is cleaned. The present application is designed in this way, so that the lowest position of the stoma can be avoided to become a cleaning dead angle.

[0064] The side hole 335 and the end face hole 336 are distributed on the peripheral surface and the bottom surface of the spray guide 330 in a regular interval, forming a full range and multi-angle spraying layout. This design ensures that after the irrigation liquid flows through each hole, it can quickly spray out through each hole to all directions, so as to realize the full coverage and effective irrigation of the stoma and its surrounding area, which not only improves the irrigation efficiency, but also ensures the effectiveness and consistency of the irrigation. For example, the side hole 335 and the end face hole 336 adopt a shower head structure design, which combines the principles of efficient irrigation and uniform distribution. The shower head structure contains a series of precisely arranged small holes or nozzles, which are differentiated in size and shape to optimize the spraying effect of the irrigation liquid. Small holes or nozzles of different sizes and shapes can produce irrigation liquid beams of different flow rates, flow rates and spraying angles, so as to form a multi-level irrigation effect in the irrigation process, ensuring that the irrigation liquid can cover and clean the stoma and its surrounding area more finely, improving the thoroughness and comfort of the irrigation.

[0065] As shown in Figure 1 and Figure 10 , the second side of the stoma bag body 100 is provided with an exhaust hole 120. The hole channel 123 of the bidirectional exhaust hole 120 penetrates the stoma bag body 100 inside and outside. The exhaust valve 121 and the plug body 122 are arranged in the hole channel 123 of the exhaust hole 120. The exhaust valve 121 is preferably a one-way exhaust valve 121, and the exhaust direction is from inside to outside. The plug body 122 is used to block the hole channel 123. The plug body 122 is detachably blocked by a connecting assembly.

[0066] The exhaust hole 120 is preferably a flexible hollow structure which can protrude from the second side of the stoma bag body 100. For example, the exhaust hole 120 is a micro-hole assembly made of flexible medical silica gel material. The exhaust hole 120 is provided with an odor eliminating assembly 124 on the wall body to avoid odor overflowing from the exhaust hole 120. The odor eliminating assembly 124 maximizes the reduction of odor diffusion, maintains the surrounding environment, and improves the comfort and satisfaction of the patient during use.

[0067] The design of the vent hole 120 aims to optimize the smoothness and efficiency of the irrigation operation. When the stoma is cleaned using the irrigation part 300, the plug 122 of the vent hole 120 can be safely pulled out, thereby establishing a communication channel between the inside of the pouch body 100 and the external atmosphere. This helps to balance the pressure inside the pouch body 100, ensuring that the irrigation liquid can flow smoothly into and cover the stoma area, while promoting the effective discharge of gas or excess liquid generated during the irrigation process, further improving the thoroughness of the irrigation and the comfort of the patient. The size of the plug 122 of the vent hole 120 matches the size of the vent hole 120. When the vent hole 120 is not in use, the plug 122 enables the pouch body 100 to maintain good airtightness, preventing liquid leakage.

[0068] According to a preferred embodiment, as shown in Figure 10 The wall of the vent hole 120 is provided with a cavity 125. The cavity 125 is provided with odor-adsorbing particles to form an odor-eliminating component 124. The odor-adsorbing particles are, for example, activated carbon. Activated carbon is specially designed for effective adsorption and removal of odor gas discharged from the inside of the pouch body 100 due to its excellent adsorption performance.

[0069] Preferably, the cavity 125 surrounds the vent hole 120 at least once. The surrounding configuration ensures that the activated carbon layer can fully contact and treat the gas flowing through the vent hole 120, thereby maximizing the odor removal efficiency.

[0070] Preferably, the bidirectional vent hole 120 can also be used as an irrigation hole when the vent valve 121 is removed. When the patient needs to irrigate the pouch body 100, the irrigation tube can be connected to the vent hole 120 to input irrigation liquid into the vent hole 120 through the irrigation tube, achieving the effect of irrigating the inside of the pouch body 100 from top to bottom.

[0071] Preferably, the odor-eliminating component 124 can also be provided on the gas passage in the valve body of the vent valve 121. In this way, the odor-eliminating component 124 can also eliminate the odor of the gas, and can be removed together with the vent valve 121, without being soaked by the irrigation liquid when the vent hole 120 is used as an irrigation hole.

[0072] According to a preferred embodiment, when the pouch body 100 is in use, the height of the irrigation part 300 is not less than the height of the first opening 210, and the overlapping area of the second opening 310 of the irrigation part 300 and the first opening 210 is not less than 50%, so that the irrigation area of the irrigation liquid in the spray guide 330 can cover the stoma. In this way, the stoma can be fully cleaned, avoiding leaving cleaning dead angles.

[0073] According to a preferred embodiment, the second opening 310 of the flushing part 300 overlaps with the first opening 210 by no less than 80% so that the flushing center of the shower guide 330 corresponds to the position of the enterostomy, thereby directing the flushing liquid to flush the enterostomy from multiple directions. In this way, the enterostomy can be cleaned comprehensively.

[0074] According to a preferred embodiment, as shown in Figure 1 Further preferably, the scale line 110 can be arranged on both side edges of the second side of the enterostomy bag body 100. In the flushing case, when the liquid outlet 140 of the enterostomy bag body 100 is closed, the scale line 110 shows the volume of the flushing liquid. The transparent window indication mark allows the patient and medical staff to intuitively understand the volume of the flushing liquid and the flushing progress. Preferably, when the bag part where the liquid outlet 140 of the enterostomy bag body 100 is located is curled and fixed by the curling fixing member 130, the liquid outlet 140 of the enterostomy bag body 100 is closed.

[0075] By reading the scale line 110, the patient can intuitively understand the volume of the flushing liquid inside the enterostomy bag body 100, thereby accurately controlling the injection amount of the flushing liquid, avoiding excessive or insufficient use, and ensuring the rationality and effectiveness of the flushing process. The scale line 110 is designed with readability and durability in consideration and is accurately calibrated to ensure clear and accurate indication effect during long-term use.
