Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an ostomy bag for collecting leakage from a drainage tube. Background Technology
[0002] With the development of medical technology, stoma surgery is increasingly widely used in the treatment of rectal tumors and intestinal trauma, and has become a common treatment method. Clinically, a drainage tube is often placed in the body cavity and inserted into an ostomy bag, allowing the drainage fluid in the tube and the exudate around the tube to flow into the ostomy bag together, or it is attached to the perianal area of patients with fecal incontinence to collect the continuously excreted excrement.
[0003] The base of modern ostomy bags is typically a patch structure with an adhesive side, which allows the patch to be attached to the patient's affected area. For cases requiring drainage tubes, there are two main methods. The first involves bending the drainage tube at the stoma opening and then attaching the patch structure to cover the patient's skin and the drainage tube. Because of the drainage tube, the base of the ostomy bag cannot easily fit completely to the patient's skin. The second method involves temporarily creating a hole in the existing ostomy bag, inserting the drainage tube through the temporary opening, and then securing the bag wall at the opening to the drainage tube securely. Both methods carry a significant risk of leakage. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an ostomy bag for collecting leakage from the drainage tube opening, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0005] The solution to the technical problem of this utility model is:
[0006] Ostomy bags, including:
[0007] Bag body;
[0008] A first base plate fixed to the bag body, the first base plate having a first adhesive surface, a central through hole, and a drainage tube fixing groove on the first adhesive surface; the first base plate having a first overlapping area.
[0009] The second base plate has a second adhesive surface. When the ostomy bag is used, the second base plate is set in the central through hole. The second base plate has a tube-through groove. The tube-through groove and the drainage tube fixing groove are staggered and the tube-through groove extends radially along the second base plate. The second base plate has a second overlapping area. The first overlapping area and the second overlapping area abut and fit together.
[0010] Through the above technical solution, the tube-passing groove is used for the drainage tube to pass through, so that one end of the drainage tube is restricted to a specific range, and the drainage tube fixing groove is used to provide space for the drainage tube to run, so that the first adhesive surface can better fit the patient's skin, thereby ensuring the leak-proof performance of the ostomy bag.
[0011] This design utilizes staggered perforation channels and drainage tube fixing channels, along with a second and a first overlapping zone. The perforation channels guide the seepage to areas away from the drainage tube fixing channel, significantly reducing leakage. The overlap between the second and first overlapping zones ensures a tighter connection between the first and second base plates, preventing seepage from flowing back to the vicinity of the drainage tube fixing channel after being guided by the perforation channels. This effectively improves the seepage-proof performance of the ostomy bag.
[0012] As a further improvement to the above technical solution, the inner wall of the drainage tube fixing groove is provided with an adhesive layer.
[0013] The above technical solution uses an adhesive layer to fix the drainage tube, thereby preventing the drainage tube from sliding relative to the ostomy bag.
[0014] As a further improvement to the above technical solution, the adhesive layer is connected to a second isolation structure.
[0015] Through the above technical solution, the second isolation structure is used to prevent the adhesive layers from sticking to each other, which would prevent the drainage tube fixing slot from opening properly, thereby preventing the drainage tube from being unable to be properly inserted into the drainage tube fixing slot, so as to ensure that the ostomy bag can be used normally.
[0016] As a further improvement to the above technical solution, the second isolation structure is release paper.
[0017] As a further improvement to the above technical solution, both the first adhesive surface and the second adhesive surface are connected to a first isolation structure.
[0018] Through the above technical solution, the first isolation structure is used to separate the first adhesive surface from the product outer packaging, and to separate the second adhesive surface from the product outer packaging, so as to prevent the first adhesive surface and the second adhesive surface from sticking to the product outer packaging respectively, thereby ensuring the adhesiveness of the first adhesive surface, the adhesiveness of the second adhesive surface, and ensuring that the ostomy bag can be smoothly removed from the outer packaging.
[0019] As a further improvement to the above technical solution, the first isolation structure is release paper.
[0020] As a further improvement to the above technical solution, both the first overlapping region and the second overlapping region are annular regions.
[0021] The above technical solution allows the annular area to achieve a good sealing effect.
[0022] As a further improvement to the above technical solution, both the first overlapping area and the second overlapping area are annular regions.
[0023] The above technical solution reduces the number of sharp edges in the annular area, thus avoiding contact between the sharp edges and the patient's skin and preventing severe discomfort.
[0024] As a further improvement to the above technical solution, the second chassis has a sealing protrusion that is snapped into the drainage pipe fixing groove.
[0025] With the above technical solution, the sealing protrusion is set together with the drainage tube in the drainage tube fixing groove, which can achieve a better anti-leakage effect.
[0026] As a further improvement to the above technical solution, the sealing protrusion is interference-fitted with the drainage tube fixing groove.
[0027] By using the above technical solution, the sealing performance between the second chassis and the first chassis is improved by setting the drainage tube fixing groove and the sealing protrusion to an interference fit.
[0028] The beneficial effects of this invention are: strong anti-seepage performance, which can effectively reduce the risk of leakage from the ostomy bag.
[0029] This invention relates to the field of medical device technology. Attached Figure Description

[0037] Reference Figures 1 to 4 An ostomy bag for collecting leakage from a drainage tube, comprising a bag body 100, a first base plate 200, and a second base plate 300.
[0038] The bag body 100 is fixedly connected to the first base plate 200.
[0039] The lower end of the bag 100 is provided with an ostomy bag discharge tube. The end of the ostomy bag discharge tube is connected to a soft plug 400 through a soft connecting strip. The soft plug 400 is used to seal the ostomy bag discharge tube. When it is necessary to drain the liquid in the bag 100, the medical staff open the soft plug 400, and then the liquid in the bag 100 can be drained from the ostomy bag discharge tube.
[0040] In this embodiment, the first chassis 200 is a disc-shaped structure. In other embodiments, the first chassis 200 may also be a square disc-shaped structure or other polygonal disc-shaped structures. Those skilled in the art can select the specific shape and structure of the first chassis 200 according to actual needs.
[0041] The first chassis 200 has a central through hole in the middle, which is a circular hole structure.
[0042] The end face of the first base plate 200 away from the bag body 100 is designated as the first adhesive surface. The first adhesive surface is coated with adhesive to make it sticky, and the first base plate 200 is attached to the patient's skin through the first adhesive surface shell. The first base plate 200 has a drainage tube fixing groove 210. Specifically, the drainage tube fixing groove 210 is formed on the first adhesive surface, and the opening of the drainage tube fixing groove 210 faces the patient's skin (or can be said to be away from the bag body 100).
[0043] Specifically, in this embodiment, the first adhesive surface is connected to a first isolation structure. The first isolation structure is used to separate the first adhesive surface from the product outer packaging to prevent the first adhesive surface from sticking to the product outer packaging, thereby ensuring the adhesiveness of the first adhesive surface and ensuring that the ostomy bag can be easily removed from the outer packaging. Specifically, in this embodiment, the first isolation structure is set as release paper, which allows the first isolation structure to be easily separated from the first adhesive surface.
[0044] Specifically, in this embodiment, the inner wall of the drainage tube fixing groove 210 is provided with an adhesive layer, which is an adhesive layer used to fix the drainage tube, thereby preventing the drainage tube from sliding relative to the ostomy bag.
[0045] Specifically, in this embodiment, the adhesive layer is connected to a second isolation structure. The second isolation structure is used to prevent the adhesive layers from sticking to each other, which would prevent the drainage tube fixing groove 210 from opening properly, thereby preventing the drainage tube from being unable to be properly inserted into the drainage tube fixing groove 210, so as to ensure that the ostomy bag can be used normally.
[0046] Specifically, in this embodiment, the first chassis 200 is provided with a first overlapping area 201, which is an annular area around the central through hole.
[0047] The second base plate 300 is a disc-shaped structure. In other embodiments, the second base plate 300 may also be a square disc-shaped structure or other polygonal disc-shaped structures. Those skilled in the art can choose the specific shape and structure of the second base plate 300 according to actual needs. Naturally, the second base plate 300 is provided with an entry channel for excrement and other substances that need to enter the ostomy bag to enter the ostomy bag.
[0048] One end face of the second chassis 300 is designated as the second adhesive surface, which is coated with adhesive.
[0049] Specifically, the second adhesive surface is also connected to a first isolation structure. The first isolation structure of the second adhesive surface has the same structure as the first isolation structure of the first adhesive surface. The first isolation structure connected to the second adhesive surface is used to separate the second chassis 300 from the outer packaging of the product, so that the second chassis 300 can be easily removed from the outer packaging of the product. In other embodiments, the first isolation structure of the second adhesive surface can also be set as a release film or other structures. Those skilled in the art can select the material or specific structure of the first isolation structure according to actual needs.
[0050] The second chassis 300 has a through-hole groove 310, which extends radially along the second chassis 300. The through-hole groove 310 connects the two end faces of the second chassis 300, and one end of the through-hole groove 310 is connected to the side wall of the second chassis 300. That is, the through-hole groove 310 is a long strip-shaped notch structure.
[0051] The tube groove 310 is used for the drainage tube to pass through so that one end of the drainage tube is restricted to a specific range.
[0052] Specifically, the second chassis 300 is provided with a second overlapping area 301, which is a circular area on the edge of the second chassis 300. The second overlapping area 301 overlaps with the first overlapping area 201. Overlapping the second overlapping area 301 and the first overlapping area 201 makes the connection between the first chassis 200 and the second chassis 300 tighter.
[0053] With the staggered arrangement of the perforation grooves 310 and the drainage tube fixing grooves 210, and the provision of a second overlapping area 301 and a first overlapping area 201, the perforation grooves 310 can guide the seepage to a certain extent, directing it to other areas away from the drainage tube fixing grooves 210, thus greatly preventing seepage from flowing out of the drainage tube fixing grooves 210. The overlap of the second overlapping area 301 and the first overlapping area 201 makes the connection between the first base plate 200 and the second base plate 300 tighter, preventing seepage from flowing back to the vicinity of the drainage tube fixing grooves 210 after being guided by the perforation grooves 310, effectively improving the seepage-proof performance of this ostomy bag.
[0054] Specifically, in this embodiment, the second chassis 300 is provided with a sealing protrusion 320, which is correspondingly provided with the drainage tube fixing groove 210. The sealing protrusion 320 and the drainage tube fixing groove 210 are snap-fitted together. Specifically, in this embodiment, the drainage tube fixing groove 210 and the sealing protrusion 320 are interference-fitted. By setting the drainage tube fixing groove 210 and the sealing protrusion 320 to an interference fit, the sealing performance between the second chassis 300 and the first chassis 200 is better.
[0055] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
