[0002] Ostomy bags are important medical devices primarily used to collect and store postoperative waste fluids and accumulated fluids. Designed with patient comfort and practicality in mind, ostomy bags are typically made of soft, waterproof, and corrosion-resistant materials such as polyvinylidene chloride, polypropylene, and polyethylene. Different types of ostomy bags are available depending on the specific application and needs. The use of ostomy bags significantly impacts a patient's quality of life. They help maintain bodily cleanliness and hygiene, while also reducing pain and discomfort. However, to ensure the effectiveness and safety of the ostomy bag, it is necessary to change it regularly, keep it clean, and closely monitor the patient's condition.

[0003] Since ostomy bags receive waste fluid, they may have some odor. Therefore, it is necessary to design some filtration and deodorization structures inside the ostomy bag. However, the existing deodorization and filtration structures are relatively simple and the deodorization and filtration effects are poor. Therefore, it is necessary to make new improvements to the existing deodorization and filtration structures. Utility Model Content

[0006] A further improvement to the above solution is that a skin-friendly and breathable membrane is provided on the side of the bag body near the bonding plate, and the skin-friendly and breathable membrane is located between the film material and the bonding plate.

[0007] A further improvement to the above solution is that the outer periphery of the skin-friendly and breathable membrane is heat-fused and pressed together with the heat-sealing ring, and the inner periphery is heat-fused and pressed together with the waste liquid inlet and the bonding plate.

[0008] A further improvement to the above solution is that the bonding disc is provided with an interface, and the outer ring of the interface is provided with multiple shearing rings, which are progressively larger.

[0009] A further improvement to the above scheme is that the drain end extends outward toward the bag body.

[0010] A further improvement to the above solution is that the encapsulation element includes a first bonding sheet and a second bonding sheet, and after the drain end is folded, the drain end is encapsulated and fixed by bonding the first bonding sheet and the second bonding sheet together.

[0011] A further improvement to the above solution is that the fixing element includes a first fixing piece and a second fixing piece, the first fixing piece and the second fixing piece are disposed opposite each other on two sides at the drain tank port, and both the first fixing piece and the second fixing piece are elastic fixing pieces.

The drainage end 14 is provided with a drainage groove 141, and one end of the drainage groove 141 is connected to the receiving cavity 12. The drainage sealing assembly 4 includes a sealing element 41 and a fixing element 42. The fixing element 42 is provided at the port of the drainage groove 141, and the sealing element 41 is used to seal and fix the folded drainage end 14. The bag body 1 of this utility model adopts a double-layer membrane structure and is connected by a heat-sealing ring 11, which effectively enhances the overall sealing and durability, ensuring that the liquid in the receiving cavity 12 will not leak out, reducing the risk of cross-infection. The double-layer structure also provides sufficient strength, making it easy to carry and replace daily, reducing the inconvenience of care caused by accidental damage. Secondly, the introduction of the filter component 2 efficiently filters and adsorbs odorous gases generated in the receiving cavity 12 through physical or chemical methods, greatly improving the patient's user experience and reducing the burden on nursing staff and the surrounding environment. This design reflects a high degree of attention to the patient's quality of life and helps promote mental health during the postoperative recovery period. Furthermore, the fitting tray 3 allows the waste liquid inlet 13 to fit tightly against the patient's skin, effectively preventing liquid leakage, while facilitating quick installation and disassembly, improving the convenience and flexibility of operation. This optimized detail reduces skin irritation or infection problems caused by improper installation. Furthermore, the drainage groove 141 of the drainage end 14, combined with the drainage sealing component 4, not only facilitates the smooth drainage of liquid, but also effectively prevents secondary contamination after drainage by fixing and sealing the folded drainage end 14 with the sealing element 41, ensuring hygiene and safety throughout the entire usage cycle. The ingenious arrangement of the fixing element 42 further enhances the stability and controllability of the drainage operation. This utility model significantly improves the convenience, safety, and comfort of postoperative care, and is an important technological innovation in the field of modern medical care.

[0021] A skin-friendly and breathable membrane 15 is provided on the side of the bag body 1 near the bonding plate 3, and the skin-friendly and breathable membrane 15 is located between the membrane material and the bonding plate 3. Specifically, the outer periphery of the skin-friendly and breathable membrane 15 is heat-fused and pressed with the heat-sealing ring 11, and the inner periphery is heat-fused and pressed with the waste liquid inlet 13 and the bonding plate 3. In this embodiment, the skin-friendly and breathable membrane 15 is located between the membrane material and the bonding plate 3, which not only optimizes the overall structure of the bag body 1, but also greatly improves the user experience. The outer periphery of the skin-friendly and breathable membrane 15 is tightly bonded to the heat-sealing ring 11 through heat-fusion pressing technology, ensuring the sealing performance of the bag body 1, effectively preventing leakage of ostomy excrement, thereby reducing the risk of skin infection. At the same time, this tight pressing method also enhances the durability of the bag body 1, making the ostomy bag more reliable during use. The inner circumference of the skin-friendly and breathable membrane 15 is heat-fused to the waste liquid inlet 13 and the bonding disc 3. This design allows liquid to smoothly enter the bag body 1 while reducing friction between the bag body 1 and the skin, thus improving wearing comfort. Furthermore, the skin-friendly properties of the breathable membrane help keep the skin dry, reducing dampness and further lowering the probability of skin inflammation. The skin-friendly and breathable membrane 15 is a non-woven fabric membrane.

[0022] The fitting disc 3 is provided with an interface 31, and the outer ring of the interface 31 is provided with multiple shear rings 32, which are progressively larger. In this embodiment, the adaptability and flexibility of the ostomy bag are enhanced. Since the size and shape of a patient's stoma may vary due to individual differences, the multiple progressively larger shear rings 32 allow medical staff to select the most suitable shear ring 32 for cutting according to the patient's specific situation, thereby ensuring that the ostomy bag can fit tightly to the patient's skin around the stoma and effectively prevent leakage. Secondly, this structure improves the comfort and safety of the ostomy bag. Through precise cutting, the ostomy bag can reduce pressure and friction on the patient's skin, reducing the risk of skin damage. At the same time, the tight fit also helps to prevent the invasion of bacteria and contaminants, protecting the patient's stoma area from infection.

[0023] The drain end 14 extends outward toward the bag body 1. Specifically, the encapsulation element 41 includes a first bonding piece 411 and a second bonding piece 412. After the drain end 14 is folded, it is encapsulated and fixed by the first bonding piece 411 and the second bonding piece 412 adhering to each other. The fixing element 42 includes a first fixing piece 421 and a second fixing piece 422. The first fixing piece 421 and the second fixing piece 422 are disposed opposite each other on two sides at the port of the drain groove 141. Both the first fixing piece 421 and the second fixing piece 422 are elastic fixing pieces. When the two ends of the fixing piece are pressed, the fixing piece will arch due to elasticity, thereby opening the drain groove 141 to drain the liquid in the accommodating cavity 12. In this embodiment, through the ingenious configuration of the encapsulation element 41, namely the use of the first bonding piece 411 and the second bonding piece 412, a stable encapsulation of the drain end 14 after folding is achieved. This process not only ensures the tight closure of the drainage end 14, effectively preventing the risk of liquid leakage, but also greatly improves the overall sealing performance of the ostomy bag. Furthermore, both fixing elements 42 are made of elastic material, i.e., elastic fixing pieces. This characteristic allows them to fit tightly against the drainage channel 141 ports of different shapes and sizes, thereby providing a more reliable and flexible fixing effect.

[0024] The filter assembly 2 includes a packaging outer shell 21, a filter membrane 22, and a filter core 23. The packaging outer shell 21 has a filter chamber, and the filter membrane 22 covers and fixes the filter core 23 inside the filter chamber. The packaging outer shell 21 has filter pores 211, which are used to connect the filter chamber to the receiving cavity 12 for filtering and discharging gas from the receiving cavity 12. The packaging outer shell 21 is a film-like packaging outer shell. The filter membrane 22 is a non-woven fabric layer; the filter core 23 is a deodorizing inner core and contains deodorizing particles inside. In this embodiment, the film-like packaging outer shell 21 not only ensures the overall structural stability and sealing of the filter assembly 2, but also improves the wearing comfort of the ostomy bag through its flexibility, reducing irritation and discomfort to the patient's skin. The filter membrane 22 is designed with a non-woven fabric layer, which has excellent air permeability and liquid barrier properties, effectively preventing the leakage of liquid inside the ostomy bag while ensuring smooth gas passage. This design ensures a dry environment inside the ostomy bag while reducing bag bloating caused by gas buildup, thus improving the patient's experience. The deodorizing inner core, the core of filter 23, contains deodorizing particles that efficiently adsorb and decompose odor-causing gases produced inside the ostomy bag, significantly reducing or eliminating odors. This alleviates the patient's psychological burden and helps maintain their social image. Furthermore, the deodorizing inner core design enhances the overall filtration efficiency of the ostomy bag, allowing for smoother gas expulsion and reducing discomfort caused by poor gas flow.
