[0001] The utility model relates to the medical field, in particular to an ostomy bag for preventing drainage tube leakage. Background Art
[0002] Clinically, a drainage tube is a silicone tube placed at the anastomosis site within the abdominal cavity or in the fossa left empty after organ removal, depending on surgical needs. Its purpose is to drain intra-abdominal exudate and blood from the body, reducing the absorption of toxins. An ostomy bag, on the other hand, is a medical device fixed to the artificial stoma to collect feces and change the patient's excretion pattern.
[0003] The following defects exist in the use of current drainage tubes:
[0004] Some intraperitoneal exudate leaks out from around the drainage tube opening, contaminating surrounding skin, clothing, and the bed, causing dampness and discomfort that requires cleaning and replacement. Furthermore, the exudate can flow along the drainage tube, causing further contamination and infection. While using an ostomy bag can somewhat prevent the overflow of exudate, since the bag and drainage tube are separate items, leakage still presents a problem during actual use. Utility Model Content

DETAILED DESCRIPTION
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] like Figures 1 to 5 The ostomy bag for preventing drainage tube leakage shown comprises a bag body 1 , a leak-proof bag 2 , a drainage tube 3 and a portable sealing structure 4 .
[0025] The bag body 1 is provided with a base 10 and an outlet 11. The bag body 1 is attached and fixed to the stoma through the base 10. The base 10 is provided with a drainage port 12 which is connected to the inside of the bag body 1. The bag body 1, base 10, outlet 11 and drainage port 12 here are the same as the basic structure of the existing ostomy bag. The outlet 11 also has a foldable and attached sealing structure, which can be used in conjunction with the portable sealing structure 4 described below to achieve a multi-layer sealing effect.
[0026] A perforation 5 for inserting the drainage tube 3 is provided on the side of the bag body 1 away from the bottom plate 10 . The leak-proof bag 2 is detachably connected to the outer edge of the perforation 5 via a docking assembly 6 , and the leak-proof bag 2 can be wrapped around the outside of the drainage tube 3 .
[0027] The side of the leak-proof bag 2 away from the perforation 5 is an opening 20 , and a portable sealing structure 4 is provided at the opening 20 to limit the outflow of liquid. An anti-seepage member is also provided on the outside of the leak-proof bag 2 .
[0028] The docking assembly 6 can be connected by attachment or magnetic fixation, or it can be a snap-on structure that has a certain waterproof effect as in the present embodiment. The docking assembly 6 in the present embodiment includes an annular groove 60 and a convex ring 61. The annular groove 60 is provided on the outer edge of the perforation 5, and the convex ring 61 is provided on the side of the leak-proof bag 2 close to the perforation 5, and the convex ring 61 is adapted to the annular groove 60. The convex ring 61 and the annular groove 60 are used to achieve preliminary protection at the bag opening of the leak-proof bag 2.
[0029] In order to increase the liquid-proof effect and the tightness of the connection state, the protruding ring 61 is made of elastic material, such as elastic silicone or elastic rubber.
[0030] In addition, the inner wall of the leak-proof bag 2 is a waterproof layer, and the anti-seepage component is a liquid-absorbing layer 21 arranged on the outside of the leak-proof bag 2. The liquid-absorbing layer 21 is made of a color-changing material, such as a phenolphthalein indicator, a methyl orange indicator, and the like. The surface color changes after absorbing the liquid.
[0031] In addition, a leak-proof layer 7 is provided on the outside of the leak-proof bag 2, and the leak-proof layer 7 is integrally connected to the surface of the leak-proof bag 2. The outside of the leak-proof layer 7 is made of waterproof material (such as PU, polyurethane, PVC), and the inside of the leak-proof layer 7 can be attached and fixed to the surface of the bag body 1.
[0032] In order to increase the effect of preventing liquid seepage, the outer surface of the opening 20 of the leak-proof bag 2 is provided with a sealing sheet 9 that is the same as the leak-proof layer 7, the outlet 11 of the bag body 1 is also provided with a portable sealing structure 4, and the inner sides of the leak-proof layer 7 and the sealing sheet 9 are both provided with waterproof glue.
[0033] The portable sealing structure 4 includes a limiting belt 40, a locking block 41 and a locking buckle 42. The limiting belt 40 includes a fixed end 43 and a movable end 44. The fixed end 43 is fixedly connected to the outer surface of the opening 20. The locking buckle 42 is arranged on the surface of the leak-proof bag 2, and the locking buckle 42 is penetrated by a card slot 45. The locking block 41 is made of elastic material (such as silicone or rubber). The locking block 41 is arranged on the surface of the movable end 44, and the side of the locking block 41 away from the fixed end 43 is an inclined portion 46. The movable end 44 can surround the opening 20 and drive the locking block 41 to pass through the card slot 45. It also includes an unlocking component 8 for releasing the restriction state of the locking buckle 42.
[0034] The lock buckle 42 includes a supporting portion 420 and a movable portion 421. The supporting portion 420 is connected to the outer surface of the opening 20. The unlocking component 8 includes a spiral spring 80 and a movable shaft 81. The movable portion 421 is rotationally connected to the supporting portion 420 through the movable shaft 81. The spiral spring 80 is respectively connected to the supporting seat and the movable shaft 81. The inner side of the supporting portion 420 and the inner side of the movable portion 421 together form a complete card slot 45.
[0035] Under normal conditions, the bag body 1, leak-proof bag 2, and drainage tube 3 are all enclosed in a sterile packaging bag. After removing the various components, during use, the convex ring 61 of the leak-proof bag 2 is first inserted into the annular groove 60 on one side of the bag body 1. The leak-proof layer 7 is then adjusted so that it adheres to the side of the bag body 1 facing away from the bottom plate 10, thereby connecting the leak-proof bag 2 and the bag body 1. Next, the drainage tube 3 is sequentially inserted through the opening 20 of the leak-proof bag 2, the perforation 5 of the bag body 1, and the drainage port 12. The ostomy bag and drainage tube 3 are then positioned according to hospital aseptic standards and properly secured according to the established operating procedures.
[0036] After the position of the drainage tube 3 is adjusted, the sealing sheet 9 is attached to the body of the drainage tube 3 at the location of the opening 20 , and the portable sealing structure 4 is used to reinforce the sealing state of the opening 20 .
[0037] Regarding the use of the portable sealing structure 4, first pull the movable end 44 of the limiting belt 40 so that the movable end 44 surrounds the drainage tube 3 where the opening 20 is located, and then insert the movable end 44 from one side of the lock buckle 42 and pass it through. Figure 5 As shown, during this process, due to the guidance of the inclined portion 46, the compression of the locking block 41 by the movable portion 421, and the appropriate movement of the movable shaft 81 when subjected to force, the locking block 41 smoothly passes through the locking slot 45 and naturally extends; afterward, the scroll spring 80 drives the movable portion 421 to return, and because the other side of the locking block 41 is not provided with the inclined portion 46, the movable portion 421 can now restrict the locking block 41, making it impossible to retract it, thereby realizing the locking function of the portable sealing structure 4. To unlock, it is necessary to actively move the movable portion 421 and simultaneously pull the limiting belt 40 to remove the locking block 41 from the lock buckle 42 in the reverse direction.
[0038] Similarly, the outlet 11 of the bag body 1 can be sealed by the portable sealing structure 4, and in conjunction with the existing sealing structure, a multi-sealing effect can be achieved. During subsequent drainage, the seepage will be blocked in the leak-proof bag 2 and the bag body 1, and a multi-liquid-proof structure consisting of a waterproof layer, a liquid-absorbing layer 21, a docking assembly 6, and a leak-proof layer 7 exists between the bag body 1 and the leak-proof bag 2.
[0039] The above is a preferred embodiment of the present invention. Those skilled in the art may make several modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered as within the scope of protection of the present invention.
