[0035] Please refer to Figure 1 、 Figure 2 and Figure 5 The utility model provides an ostomy bag in a preferred embodiment, comprising a base plate 100, a mesh structure 200, a connecting plate 300 and a bag body 400.
[0036] The base 100 has a fistula opening 101 at its center, and its overall contour can be circular. An adhesive layer 110 is provided on the front of the base 100, and a recess 120 is provided on the back edge of the fistula opening 101. Positioning posts 121 are located within the recess 120. The base 100 can be made of silicone or medical hydrocolloid. The adhesive layer 110 can be made of hydrogel, silicone tape, fibrin adhesive, or polysaccharide adhesive (such as chitosan), and can adhere to human skin.
[0037] The mesh structure 200 is embedded in the groove 120, providing a positioning effect. The mesh structure 200 is provided with positioning holes 210 for the positioning posts 121 to engage, thereby providing a positioning and limiting effect on the mesh structure 200. Specifically, the groove 120 and the mesh structure 200 have circular contours. The mesh structure 200 has multiple overflow holes 220 distributed corresponding to the fistula opening 101, allowing for the smooth discharge of excrement.
[0038] The connecting disc 300 is connected to the rear side of the base plate 100. A clearance hole 301 is provided in the center of the connecting disc 300 to allow for the stoma 101 to pass through. The central portion of the connecting disc 300 covers the rear edge of the mesh structure 200. Specifically, the diameter of the clearance hole 301 is smaller than the outer diameter of the mesh structure 200. This causes the edge of the clearance hole 301 to press against the outer edge of the mesh structure 200, limiting the mesh structure 200 and preventing it from dislodging from the embedded groove 120 when resisting internal pressure. It is understood that the connecting disc 300 can be attached to the base plate 100 by adhesive. The connecting disc 300 and the base plate 100 are both circular and concentrically arranged.
[0039] The bag body 400 is connected to the connection plate 300 , and the bag body 400 is used to receive substances (excrement) overflowing from the overflow hole 220 .
[0040] The present invention provides an ostomy bag. The adhesive layer 110 of the base plate 100 ensures a tight fit between the bag and the patient's skin, effectively preventing excrement leakage. The inlay groove 120 and positioning post 121 ensure the accurate positioning of the mesh structure 200. The middle portion of the connecting plate 300 covers the rear edge of the mesh structure 200, limiting the edge of the mesh structure 200. The overflow hole 220 of the mesh structure 200 allows excrement to flow smoothly into the bag body 400, while effectively preventing the intestinal tract from prolapsing or escaping from the ostomy opening 101. The bag body 400 then receives material (excrement) that overflows from the overflow hole 220.
[0041] Reference Figure 3 and Figure 4 In some embodiments of the present invention, a positioning hole 210 extends from the rear end of the positioning post 121 and is provided with a limiting protrusion 122. The limiting protrusion 122 is perpendicular to the extension direction of the positioning post 121 and effectively prevents the mesh structure 200 from disengaging from the recess 120. Specifically, the mesh structure 200 is made of silicone, which allows for a certain degree of elastic deformation, improving skin-friendliness and comfort. Furthermore, the silicone mesh structure 200 easily deforms during installation, allowing the positioning hole 210 to pass over the limiting protrusion 122 and fit over the positioning post 121.
[0042] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the positioning posts 121, the limiting protrusions 122 and the positioning holes 210 are arranged in multiple groups around the fistula opening 101, thereby achieving a multi-position positioning effect.
[0043] In some embodiments of the present invention, the bag body 400 is detachably connected to the connecting plate 300. This makes it easy to remove and replace the bag body 400 without having to frequently replace the entire bag body. This avoids the need to frequently tear off the chassis 100 due to frequent replacement of the chassis 100, effectively reducing the number of times the chassis 100 needs to be removed and replaced, thereby improving the utilization rate of the chassis 100 and user comfort.
[0044] Of course, in some other embodiments, the bag body 400 and the connecting disk 300 can also be an integrally formed structure, for example, the bag body 400 and the connecting disk 300 are bonded together using glue. The bag body 400 can be made of medical plastic material, such as polypropylene (PP) or polypropylene (PP) material.
[0045] Reference Figure 6 and Figure 7The cam 320 is provided with a protruding portion 320 for locking the cam 320 in the locking cam 320 so as to lock the cam 320. When the cam 320 is unlocked, the cam 320 is unlocked and the cam 320 is unlocked. The elastic deformation of the locking protrusion 330 allows the inner convex ring 420 to pass over the locking protrusion 330 and snap into the snap groove 340, thereby achieving a detachable connection between the connecting disc 300 and the bag body 400. A storage cavity is formed within the bag body 400, and a docking port is formed at the collar portion 410 for excrement to enter. A discharge pipe can be provided at the bottom of the bag body 400, and a sealing plug can be provided on the discharge pipe to control whether it is blocked or released. The collar portion 410 is mounted on the outer periphery of the locking protrusion 330 to provide a centering effect. The collar portion 410 and the bag body 400 can be bonded together by adhesive or welded.
[0046] In order to facilitate manufacturing, reduce the number of parts and improve connection stability, the ring portion 410 and the inner convex ring 420 can also be manufactured by integral molding. The ring portion 410 and the inner convex ring 420 can be made of medical plastic material, such as polypropylene (PP) or polypropylene (PP).
[0047] Reference Figure 7 In a further embodiment of the present invention, the rear side of the base plate 310 is provided with an elastic protrusion 311 that abuts against the inner convex ring 420, thereby reducing structural gaps and allowing the inner convex ring 420 to closely contact the locking protrusion 330. Due to the presence of the elastic protrusion 311, during installation, the inner convex ring 420 can press against the elastic protrusion 311, allowing the elastic protrusion 311 to move forward more easily to pass over the locking protrusion 330. After release, the elastic protrusion 311 rises again, allowing the inner convex ring 420 to closely contact the locking protrusion 330, thereby reducing structural gaps. To facilitate manufacturing, reduce the number of parts, and improve connection stability, the base plate 310, convex ring 320, and locking protrusion 330 can be integrally molded. Specifically, the connecting plate 300 can be made of silicone, so that the elastic protrusion 311 and the locking protrusion 330 have good elastic deformation capabilities.
[0048] Reference Figure 1In a further embodiment of the present invention, a binding ear 350 separated from the bottom plate 100 is provided on the outer peripheral side of the base plate 310, and the binding ear 350 is provided with a binding hole 351, and a strap can be tied or hooked to the binding hole 351, so that the fistula bag can be tied to the human body with the strap.
[0049] Reference Figure 2 In a further embodiment of the present invention, the front side of the adhesive layer 110 is connected to a release paper 111, and the release paper 111 is provided with a tearing ear 112 on the side thereof, so as to prevent the adhesive layer 110 from sticking to the packaging bag during packaging, and also prevent the adhesive layer 110 from sticking to other structures when taking out, thereby affecting use. The release paper 111 can effectively prevent the adhesive layer 110 from sticking to other structures before use; when the fistula bag needs to be taken out, the release paper 111 can be easily torn off by tearing the tearing ear 112.
[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
