Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of ostomy bags, and in particular relates to a backflow-proof multifunctional ostomy bag connecting device. Background Art
[0002] A stoma is an artificial opening made in the abdominal wall of a human body through surgery to discharge waste or gas from the body. Among them, a urinary stoma is a surgical connection between the urethra and the outside to help patients urinate. Stoma surgery is usually used clinically to provide necessary life support for patients who are unable to excrete normally after treating certain serious diseases or injuries.
[0003] Generally, an ostomy bag is adhered to the patient's skin with an adhesive patch, and the waste excreted from the patient's stoma flows directly into the bag through the inlet on the bag. Since there is no muscle near the stoma for closing the stoma, when the patient's body position changes, the excrement inside the bag may flow back to the vicinity of the stoma, which will not only contaminate the patient's skin and increase the risk of infection, but may also cause the bag to rupture, leak, and have an odor. Therefore, the existing ostomy bag needs to be improved to effectively prevent the excrement inside the bag from flowing back. Summary of the invention
[0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a multifunctional ostomy bag connection device for preventing backflow, so as to solve the problem that the existing ostomy bags have no structure to prevent the backflow of internal excrement.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] A backflow prevention multifunctional ostomy bag connection device, comprising:
[0007] A bag body, used for holding stoma excreta, the bag body is connected with a bag opening, and the bag opening is fixedly connected with a mounting ring for attaching to the patient's body surface;
[0008] An anti-backflow block is arranged inside the bag opening and is used to connect the bag body and the bag opening;
[0009] A discharge valve is arranged at the lower end of the bag body and is used to discharge the excrement collected inside the bag body to the outside.
[0010] Preferably, a plurality of backflow prevention channels are arranged inside the backflow prevention block, and the backflow prevention channels include a main channel arranged in multiple bends and a secondary channel connected to the bends of the main channel, and the secondary channel is arranged in a J shape.
[0011] Preferably, a baffle is rotatably connected to the inner wall of the backflow prevention block, and the baffle is arranged at the connection between the main flow channel and the secondary flow channel.
[0012] Preferably, the backflow prevention block and the baffle are both made of plastic.
[0013] Preferably, the drain valve comprises an outlet pipe connected to the bottom of the bag body and a mounting pipe connected to the outlet pipe, and a start-stop plug for blocking the outlet pipe is inserted into the mounting pipe.
[0014] Preferably, a drainage channel is provided on the start-stop plug, and a plurality of spirally arranged connecting strips are fixedly connected to the end of the start-stop plug, and an end block is fixedly connected to the end of the connecting strip.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The present invention provides an anti-backflow block at the connection between the bag body and the bag opening. When the patient puts on the ostomy bag, the ostomy excrement can flow from the bag opening into the bag body via the anti-backflow block. When the positions of the bag body and the bag opening are reversed, the anti-backflow block can effectively limit the excrement in the bag body from flowing back to the bag opening, thereby effectively preventing the ostomy infection caused by the reflux of waste, and reducing the possibility of rupture, leakage or odor of the ostomy bag caused by the backflow, so that the patient can use the ostomy bag with more peace of mind and reduce the concerns when using the ostomy bag.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.
[0025] Embodiment 1:
[0026] See also Figure 1 - Figure 6 As shown, a backflow prevention multifunctional ostomy bag connection device comprises:
[0027] A bag body 1 is used to hold stoma excrement, the bag body 1 is connected to a bag opening 2, and the bag opening 2 is fixedly connected to a mounting ring 3 for attaching to the patient's body surface;
[0028] The backflow prevention block 4 is arranged inside the bag opening 2 and is used to connect the bag body 1 and the bag opening 2;
[0029] The discharge valve is arranged at the lower end of the bag body 1 and is used for discharging the excrement collected inside the bag body 1 to the outside.
[0030] As can be seen from the above, by providing an anti-backflow block at the connection between the bag body 1 and the bag opening 2, and providing a mounting ring 3 on the bag opening 2, when the patient puts on the ostomy bag through the mounting ring 3, the ostomy excrement can flow from the bag opening 2 into the bag body 1 via the anti-backflow block 4. When the positions of the bag body 1 and the bag opening 2 are reversed, the anti-backflow block 4 can effectively limit the excrement in the bag body 1 from flowing back to the bag opening 2, thereby effectively preventing the ostomy infection caused by the reflux of waste, and reducing the rupture, leakage or odor of the ostomy bag that may be caused by the backflow, so that patients can use the ostomy bag more safely and reduce their concerns when using the ostomy bag. When the waste inside the ostomy bag needs to be discharged, it can be discharged through the discharge valve, thereby extending the use time of the ostomy bag.
[0031] Embodiment 2:
[0032] See also Figure 1 - Figure 6 As shown, a backflow prevention multifunctional ostomy bag connection device comprises:
[0033] A bag body 1 is used to hold stoma excrement, the bag body 1 is connected to a bag opening 2, and the bag opening 2 is fixedly connected to a mounting ring 3 for attaching to the patient's body surface;
[0034] The backflow prevention block 4 is arranged inside the bag opening 2 and is used to connect the bag body 1 and the bag opening 2;
[0035] The discharge valve is arranged at the lower end of the bag body 1 and is used for discharging the excrement collected inside the bag body 1 to the outside.
[0036] As can be seen from the above, by providing an anti-backflow block at the connection between the bag body 1 and the bag opening 2, and providing a mounting ring 3 on the bag opening 2, when the patient puts on the ostomy bag through the mounting ring 3, the ostomy excrement can flow from the bag opening 2 into the bag body 1 via the anti-backflow block 4. When the positions of the bag body 1 and the bag opening 2 are reversed, the anti-backflow block 4 can effectively limit the excrement in the bag body 1 from flowing back to the bag opening 2, thereby effectively preventing the ostomy infection caused by the reflux of waste, and reducing the rupture, leakage or odor of the ostomy bag that may be caused by the backflow, so that patients can use the ostomy bag more safely and reduce their concerns when using the ostomy bag. When the waste inside the ostomy bag needs to be discharged, it can be discharged through the discharge valve, thereby extending the use time of the ostomy bag.
[0037] See also Figure 3 - Figure 6 As shown, a plurality of anti-backflow channels are arranged inside the anti-backflow block 4, and the anti-backflow channels include a main channel 41 arranged in multiple bends and a secondary channel 42 connected to the bends of the main channel 41, and the secondary channel 42 is arranged in a J shape.
[0038] When excrement flows from the top of the anti-backflow block 4 to the bag body 1 through the anti-backflow channel, the excrement mainly flows through the main channel 41. At this time, the secondary channel 42 has a section of the flow direction that is set upward and has a large flow resistance. Some excrement will flow downward from the secondary channel 42. At this time, the excrement inside the anti-backflow channel is subject to a smaller flow resistance as a whole. Therefore, the excrement can flow from the bag mouth 2 to the inside of the bag body 1. When the excrement in the bag body 1 flows back to the bag mouth 2 through the anti-backflow block 4, the excrement will be diverted to the main channel 41 and the secondary channel 42 at the same time. Since the secondary channel 42 is J-shaped, the flow direction of the excrement at the end of the secondary channel 42 is opposite to the flow direction of the excrement in the main channel 41, which can increase the flow resistance of the excrement inside the main channel 41. At this time, the excrement is subject to a larger flow resistance as a whole. After being blocked by multiple secondary channels 42, the backflow amount of excrement can be effectively reduced.
[0039] See also Figure 4 - Figure 6As shown, although the arrangement of the main channel 41 and the secondary channel 42 can effectively increase the backflow resistance of excrement, and thus effectively prevent the backflow of excrement, it is impossible to completely prevent the backflow of excrement. Therefore, a baffle 43 is rotatably connected to the inner wall of the anti-backflow block 4, and the baffle 43 is arranged at the connection between the main channel 41 and the secondary channel 42. When the excrement under the anti-backflow channel flows back, the excrement flowing in the secondary channel 42 will push the baffle 43 to tilt, and the excrement flowing in the main channel 42 will also push the inclined baffle 43. At this time, the baffle 43 is pushed by the excrement in the main channel 41 and the secondary channel 42 to rotate, and the rotating baffle 43 will block and cut off the main channel 41, prevent the excrement inside the main channel 41 from flowing back, and thus effectively cut off the backflow of excrement, which can reduce the backflow of excrement as much as possible.
[0040] In order to reduce the overall mass of the anti-backflow block 4 as much as possible and improve the installation stability of the bag opening 2, the anti-backflow block 4 and the baffle 43 are both made of plastic, which also facilitates the manufacture of the anti-backflow block 4 and the baffle 43.
[0041] See also Figure 1 - Figure 4 As shown, the discharge valve includes an outlet pipe 5 connected to the bottom of the bag body 1 and a mounting pipe 6 connected to the outlet pipe 5, a start-stop plug 7 for blocking the outlet pipe 5 is inserted inside the mounting pipe 6, the outlet pipe 5 and the mounting pipe 6 are arranged in a cross shape, the outlet pipe 5 can discharge the excrement in the bag body 1 to the outside, when the outlet pipe 5 needs to be closed, it is only necessary to slide the start-stop plug 7 to block the mounting pipe 6 to cut off the passage of the outlet pipe 5.
[0042] In order to prevent the start-stop plug 7 from bringing external dust into the bag body 1 during the plugging and unplugging process, a drainage channel 71 can be opened on the start-stop plug 7, and a plurality of spirally arranged connecting strips 72 are fixedly connected to the end of the start-stop plug 7, and the end of the connecting strip 72 is fixedly connected to an end block 73. During use, there is no need to pull out the start-stop plug 7. When it is necessary to discharge the excrement inside the bag body 1 through the outlet pipe 5, it is only necessary to press the start-stop plug 7 so that the start-stop plug 7 squeezes the connecting strip 72 inward, forcing the connecting strip 72 to bend and deform. At this time, the start-stop plug 7 can move inward and push the drainage channel 71 to the connection position with the outlet pipe 5. At this time, the excrement inside the bag body 1 will be discharged outward through the outlet pipe 5 and the drainage channel 71.
