Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical devices, and in particular relates to an ostomy bag with good sealing performance and the ability to be flushed and vented. Background Art
[0002] Ostomy bags are medical supplies used by people with anorectal, urethral, or double-lumen stomas to store excreta. Commercially available ostomy bags typically have a sealing ring and a sealing cover that are connected to the bag body via a flexible connector. When opened for venting or flushing, the sealing ring and the cover, which separate from the bag's external outlet along with the sealing cover, are often contaminated with excreta. Therefore, when patients open the cover to vent or flush the bag, excreta can easily contaminate the bag body and clothing. Furthermore, existing ostomy bags have a drawback of poor sealing performance, often causing gas inside the bag to escape through gaps in the sealing cover, leading to odor and embarrassment for patients and loss of privacy. Utility Model Content
[0003] The utility model provides an ostomy bag with good sealing performance and capable of being flushed and vented, aiming to overcome the above-mentioned shortcomings of conventional ostomy bags in the prior art.
[0004] The utility model solves the above technical problems with the following technical solutions: an ostomy bag with good sealing performance and capable of flushing and exhausting, comprising an ostomy bag body, a sealing ring and a sealing cover, wherein the sealing ring is adhered and fixed to the outer discharge port of the ostomy bag body after being overlapped by an outer ring sheet, a columnar plug is provided at the center of the lower surface of the sealing cover, an upward convex ring and a downward convex ring are provided at the center of the sealing ring, an annular platform extending toward the center of the sealing ring and parallel to the outer ring sheet, and a downwardly folded elastic spring is provided on the inner side of the annular platform The elastic convex ring is provided with an annular relief groove between the elastic convex ring and the downward-turned convex ring. The inner side surfaces of the elastic convex ring and the annular platform jointly constitute a center hole for the cylindrical plug to be detachably inserted and sealed. The lower end of the cylindrical plug is provided with a circle of outward-turned sealing bosses. The periphery of the lower surface of the sealing cover is pressed tightly against the upper surfaces of the upward-turned convex ring and the annular platform to form two seals. The inner side surface and the lower end surface of the elastic convex ring are respectively pressed tightly against the cylindrical surface of the cylindrical plug and the upper surface of the sealing boss to form another two seals.
[0005] On the basis of the above technical solution, the present invention can also be improved as follows.
[0006] Furthermore, a ring groove coaxial with the upward convex ring is provided on the upper surface of the annular platform.
[0007] Furthermore, an annular gap is left between the outer edge of the downwardly turned convex ring and the periphery of the outer discharge port.
[0008] Furthermore, the annular gap is coated with elastic sealant.
[0009] Furthermore, an extension cover piece is provided on the edge of the sealing cover, and anti-slip grooves are provided on the upper and lower surfaces of the extension cover piece.
[0010] Furthermore, the sealing ring is integrally formed of elastic plastic.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] The sealing ring and sealing cover are separate and bonded to the pouch's outlet. The sealing ring is removably sealed and connected to the center hole of the sealing ring. For flushing or venting, simply remove the sealing cover. The sealing cover is less susceptible to contamination from fecal matter and, being separate from the pouch, is less likely to contaminate the pouch or clothing. Furthermore, the sealing cover's cylindrical plug, inserted into the center hole of the sealing ring, creates a multi-layer seal, ensuring a strong seal. During daily use, the bag's contents are protected from accidental leakage and are odorless, ensuring a positive user experience and excellent privacy. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0021] In the description of the present invention, if terms indicating directions such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used, the directions or positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.
[0022] like Figures 1 to 5 As shown, the utility model provides an ostomy bag with good sealing performance and flushable exhaust, comprising an ostomy bag body 1, a sealing ring 2 and a sealing cover 3. The sealing ring 2 is adhered and fixed to the outer discharge port on the ostomy bag body 1 after being overlapped by an outer ring sheet 4. A columnar plug 5 is provided at the center of the lower surface of the sealing cover 3. An upward convex ring 6 and a downward convex ring 7 are provided at the center of the sealing ring 2. The upper edge of the upward convex ring 6 extends toward the center of the sealing ring 2 and is parallel to the annular platform 8 of the outer ring sheet 4. A downward-folded elastic convex ring 9 is provided on the inner side of the annular platform 8. An annular relief groove 10 is formed between the elastic convex ring 9 and the downward-turned convex ring 7. The inner side surfaces of the elastic convex ring 9 and the annular platform 8 jointly constitute a center hole for the cylindrical plug 5 to be detachably inserted and sealed. The lower end of the cylindrical plug 5 is provided with a circle of outward-turned sealing bosses 11. The periphery of the lower surface of the sealing cover 3 is pressed tightly against the upper surfaces of the upward-turned convex ring 6 and the annular platform 8 to form two seals. The inner side surface and lower end surface of the elastic convex ring 9 are respectively pressed tightly against the cylindrical surface of the cylindrical plug 5 and the upper surface of the sealing boss 11 to form another two seals.
[0023] It should be noted that the annular relief groove can ensure that when the cylindrical plug is inserted into the center hole of the sealing ring when the sealing cover is closed, the elastic convex ring can be squeezed and moved outward. When the sealing boss is fully inserted, the elastic convex ring rebounds and presses the peripheral wall of the cylindrical plug. At the same time, the upper surface of the sealing boss is also tightly pressed against the lower end surface of the elastic convex ring, which plays a sealing role on the one hand and prevents the sealing cover from falling out on the other hand.
[0024] In one embodiment of the present invention, a ring groove 12 coaxial with the upward raised ring 6 is formed on the upper surface of the annular platform 8 .
[0025] It should be noted that the provision of the annular groove is conducive to enhancing the effect of the elastic convex ring being deformed by extrusion and restoring the sealing effect by extruding the peripheral wall of the cylindrical plug.
[0026] In one embodiment of the present invention, an annular gap is left between the outer edge of the downwardly turned convex ring 7 and the periphery of the outer discharge port, and the annular gap can be filled with elastic sealant.
[0027] It is understandable that the peripheral ring piece is overlapped and fitted with the bag body around the outer discharge port of the ostomy bag and fixedly connected by heat sealing, or it can be glued and fixed by waterproof glue, and the annular gap can be cured and sealed by the same type of glue.
[0028] In one embodiment of the present invention, an extension cover piece 13 is provided on the edge of the sealing cover 3 , and anti-slip grooves 14 are provided on the upper and lower surfaces of the extension cover piece 13 .
[0029] It should be noted that the anti-slip patterns may be convex strips arranged in parallel and at intervals.
[0030] In one embodiment of the present invention, the sealing ring 2 is integrally formed from elastic plastic. In other words, the sealing ring can be integrally formed from one plastic by a mold, and the peripheral ring piece, the upwardly turned convex ring, the downwardly turned convex ring, the annular platform and the elastic convex ring are all formed simultaneously in the mold.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
