Description

Technical Field

[0001] This utility model relates to the technical field of ostomy bags, and in particular to a non-removable universal ostomy bag with an integrated infusion channel. Background Technology

[0002] Ostomy bags, as important medical devices for collecting human excrement, are widely used in the daily care of ostomy patients. They mainly consist of a base and a bag, with common connection methods including snap-fit, adhesive, and threaded connections. In a fecal microbiota perfusion intervention study of patients with double-panicle ileostomy, ostomy bags were used to collect stoma contents. After dilution with physiological saline, vortexing, and filtration, the filtered liquid was perfused into the distal intestinal tract to improve intestinal dysfunction caused by intestinal atrophy and intestinal barrier damage.

[0003] The current fecal microbiota instillation procedure is as follows: first, the contents of the ostomy bag are emptied and processed; then, the ostomy bag is removed, and a double-lumen catheter with an inflated balloon is inserted into the distal intestinal tract for fixation; next, the filtered fluid is instilled via IV drip; after instillation, the balloon is aspirated, the catheter is removed, and finally, the ostomy bag is reattached. However, this instillation method has many problems: the operation steps are complicated, and repeatedly removing and putting on the ostomy bag not only increases the difficulty of nursing care but also emits an irritating odor, affecting patients and nursing staff; repeated intubation can easily cause pain to patients and reduce treatment compliance; in addition, since instillation needs to be performed daily and the cycle is long, it is difficult for family members to perform the operation independently at home, which greatly limits the application of fecal microbiota instillation intervention in home settings. Utility Model Content

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-7 As shown, a non-removable universal ostomy bag with an integrated infusion channel is provided, including an ostomy bag 1, a base plate 2 detachably connected to one side of the ostomy bag 1, a catheter 3 inside the ostomy bag 1, one end of the catheter 3 penetrating the base plate 2, a connecting mechanism on the side of the ostomy bag 1 away from the base plate 2, and a drip tube 13 on the side of the ostomy bag 1 away from the base plate 2, and the drip tube 13 is connected to the connecting mechanism through a fixing component; in this example, the material and diameter of the drip tube 13 can be referenced to the feeding tube, the purpose of which is to ensure that it can be injected with fluid and can also be delivered normally when injecting some viscous liquids; the connecting mechanism includes a fixing seat 4, and the fixing seat 4 is fixedly embedded in the side of the ostomy bag 1 away from the base plate 2, a connecting tube 5 is symmetrically arranged inside the fixing seat 4, and a connector connected to the connecting tube 5 is symmetrically arranged on the side of the fixing seat 4 near the catheter 3, and the connector is detachably connected to the catheter 3, and an air injection tube 9 and an injection tube 10 communicating with the connecting tube 5 are provided on the side of the fixing seat 4 away from the catheter 3.

[0029] In this example, the connecting mechanism also includes a rubber block 11, which is fixedly installed on the inner side of the end of the insufflation tube 9 away from the fixed seat 4. Several rubber flaps 12 are symmetrically arranged on the side of the rubber block 11 near the fixed seat 4. A valve seat 14 is fixedly installed on one side of the infusion tube 10, and a valve stem 15 is rotatably installed on one side of the infusion tube 10. One end of the valve stem 15 is connected to a valve ball 16 inside the valve seat 14, and the valve ball 16 is adapted to the valve seat 14. This allows for infusion without disassembly, effectively avoiding the emission of irritating odors, and simplifying the operation process. After infusion, only the gas in the air bag 25 needs to be withdrawn from the outside of the ostomy bag 1, without removing the catheter 3. This greatly reduces the cumbersome operation steps. The operation is simple and easy to understand, making it convenient for family members to complete the infusion operation at home. This not only reduces the difficulty of nursing care but also alleviates the pain and discomfort caused by repeated intubation for patients.

[0030] In this example, the connector includes a connector 6, which is symmetrically arranged on the side of the fixed seat 4 near the catheter 3. The connector 6 is connected to the connecting tube 5. The connector 6 has a connector 7 on its inner side, which is fixedly connected to the catheter 3. A fixing sleeve 8 is rotatably installed on the outer side of the connector 7, and the inner wall of the fixing sleeve 8 is threadedly connected to the outer wall of the connector 6. The connector facilitates the assembly and disassembly of the catheter 3 and the ostomy bag 1, and makes it easy to disassemble and replace the catheter 3.

[0031] In this example, several rubber flaps 12 are combined into a cone shape, the connector 7 is a frustum-shaped structure, and the connector 6 is adapted to the connector 7 so that the rubber flaps 12 can be used to seal the air injection pipe 9, which acts as a valve. The structural design of the connector 7 allows it to fit tightly against the inner wall of the connector 6, ensuring good sealing performance.

[0032] In this example, the catheter 3 includes an insertion tube 22, one end of which is connected to an injection end 24. An injection end 23 is located at the end of the insertion tube 22 near the injection end 24. An air delivery chamber 26 is formed inside the side wall of the insertion tube 22 and communicates with the injection end 23. An air bag 25, communicating with the air delivery chamber 26, is located on the outer side of the end of the insertion tube 22 away from the injection end 23. Several injection holes are provided at the end of the insertion tube 22 away from the injection end 23. In this example, the catheter 3 is 20 cm long to facilitate injection of fluid into the distal intestinal tract. The air bag 25 is used for positioning and fixation. In this example, one end of each of the two fixing sleeves 8 is fixedly connected to the injection end 23 and the injection end 24, respectively. The catheter 3 is a flexible tube.

[0033] Reference Figures 2-6 As shown, in this example, the fixing component includes a metal spring 18, which is symmetrically arranged on the outside of the drip tube 13. The end of the metal spring 18 near the injection tube 10 is fixedly connected to the drip tube 13. A docking seat 17 adapted to the drip tube 13 is installed inside one end of the injection tube 10, and a valve seat 14 is sleeved on the outside of one end of the drip tube 13. In this example, the end of the drip tube 13 near the docking seat 17 has a frustum-shaped structure, and the docking seat 17 is adapted to it to ensure good sealing when the two are connected. A connecting ring 19 is slidably sleeved on the outside of the drip tube 13, and the connecting ring 19 is fixedly connected to the metal spring 18. The outer wall of the connecting ring 19 is symmetrically provided with support blocks 20. The fixing component can conveniently and quickly connect and fix or separate the drip tube 13 and the injection tube 10 for subsequent injection.

[0034] In this example, the metal spring 18 has a semi-circular structure at one end near the docking seat 17. The inner wall of the docking seat 17 is symmetrically provided with slots 21 that are adapted to the metal spring 18. The top surface of the support block 20 is an arc surface, and the inner wall of the arc surface is provided with several anti-slip textures so that one end of the semi-circular structure of the metal spring 18 can be inserted into the slot 21 to restrict and fix the drip tube 13. The anti-slip textures can increase the friction so as to better drag the support block 20 to move.

[0035] During use, the connection between the catheter 3 and the fixed seat 4 is achieved by aligning one end of the connector 7 with the corresponding connector 6 and threading the fixing sleeve 8 to the connector 6. Then, the base plate 2 can be attached and fitted onto the outside of the distal intestinal tract. The end of the catheter 3 furthest from the ostomy bag 1 is then inserted into the distal intestinal tract, and the ostomy bag 1 is finally connected and fixed to the base plate 2. When intravenous infusion is required, one end of the drip tube 13 can be directly inserted into the inner side of the docking seat 17. Simultaneously, one end of the semi-circular structure of the metal spring 18 will be squeezed and pushed by the inner wall of the docking seat 17, causing the semi-circular end of the metal spring 18 to deform and move downwards. When the outer wall of the drip tube 13 is tightly fitted with the inner wall of the docking seat 17, one end of the semi-circular structure on the metal spring 18 corresponds to the slot 21, and it will elastically reset, thereby locking one end of the metal spring 18 into the slot 21, thus restricting and fixing the drip tube 13 and completing the docking between the drip tube 13 and the docking seat 17. Then, using a syringe, one end of it is passed through the rubber block 11 and gradually pushed the rubber flaps 12, so that the middle position of several rubber flaps 12 is opened. Then, air can be pumped through the syringe, so that the gas is delivered to the connected air injection end through the air injection tube 9 and the connecting tube 5 connected to the air injection tube 9. 23. The syringe is then inserted into the gas delivery chamber 26, and then into the balloon 25 to inflate it, so that the balloon 25 restricts and fixes the end of the cannula 22 in the distal intestinal tract. Then the syringe can be removed, and the rubber flap 12 returns to its original position under its elastic force, so that several rubber flaps 12 cooperate to seal the gas injection tube 9 and prevent gas from flowing out. Then the valve stem 15 can be turned to drive the valve ball 16 to rotate, so that the injection tube 10 is connected to the connected connecting tube 5, and the injection operation can be performed. After use, the valve stem 15 is turned to drive the valve ball 16 to cooperate with the valve seat 14 to seal and close the injection tube 10. Then the support block 20 is dragged to drive the connected connecting tube 5. The connecting ring 19 slides on the drip tube 13, thereby pulling the metal spring 18, causing one end of the semi-circular structure on one side of the metal spring 18 to deform and move out of the slot 21. Then the drip tube 13 can be separated from the docking seat 17. After that, the syringe is used again to connect one end to the air injection tube 9. The rubber flap 12 is opened again to draw out the gas in the air bag 25, releasing the restriction on the intubation tube 22. This eliminates the need to remove the catheter 3, greatly reducing the cumbersome operation steps. The operation is simple and easy to understand, making it convenient for family members to perform the infusion operation at home. This not only reduces the difficulty of nursing care but also reduces the pain and discomfort caused by repeated intubation for patients.
