Description

Technical Field

[0001] The utility model relates to the technical field of ostomy bags, in particular to an ostomy bag which can be conveniently disassembled and assembled with a chassis. Background Art

[0002] Patients who have undergone abdominal stoma surgery cannot defecate normally through the anus. Instead, a colostomy is opened in the abdomen and a stoma bag that matches the colostomy is worn to discharge feces into the stoma bag through the colostomy.

[0003] The existing two-piece ostomy bags on the market include a base that fits the abdomen and a bag body that is detachably connected to the base. Connecting rings for mutual connection are provided between the bag body and the base, and the two sets of connecting rings are fastened together by an annular snap buckle. When the existing bag body is fastened with the base, it is necessary to pinch the traction piece provided on the outer wall of the connecting ring on one side of the bag body with one hand, move the connecting ring on one side of the bag body toward the connecting ring on one side of the base, and finally complete the fastening connection.

It is limited by two sets of limiting protrusions 18 to avoid separation. At this time, the plastic strip 6 forms a ring shape and is sleeved in the ring groove 5 without falling off.

[0033] Working principle: the bag body 1 and the chassis 2 are fixed by buckling the undercut edge 14 and the connecting groove 10. The bag body 1 is moved closer to the chassis 2, and the undercut edge 14 is completely buckled in the connecting groove 10, so that the bag body 1 and the chassis 2 are connected. The bag body 1 will not fall off during use through the buckling of the undercut edge 14 and the connecting groove 10. When the first connecting plate 3 and the second connecting plate 4 are connected, the second convex ring 15 just enters the sealing groove 13. The second convex ring 15 and the two groups of first convex rings 12 form a sealing structure to prevent excrement from leaking from the connection between the first connecting plate 3 and the second connecting plate 4. The auxiliary structure is slidably connected to the annular groove 5, so that the socket 7 can rotate along the annular groove 5 to cover all contact surfaces between the undercut edge 14 and the connecting groove 10. By rotating the two groups of sockets 7 to a front-to-back relative state, and then pinching the two groups of sockets 7 with the thumb and index finger, and pressing hard, the undercut edge 14 between the two groups of sockets 7 can be easily pressed. When disassembling, hold a socket 7 with both hands respectively, and move the socket 7 on the bag body 1 to the side away from the abdomen, so that the undercut edge 14 can be easily withdrawn from the connecting groove 10. The bag body 1 will not press on the abdomen when connected to the chassis 2, and it is very easy to apply force. The plug-in block 8 is inserted into the slot 16 on the socket 7, and the positioning rod 9 enters the slide groove 17, and the positioning rod 9 is pushed into the short groove of the slide groove 17. It is limited by two sets of limiting protrusions 18 to avoid separation. At this time, the plastic strip 6 forms a ring shape and is sleeved in the ring groove 5 without falling off.
