[0035] Embodiment: As Figure 1As shown in the figure, a stoma bag for abdominal surgery drainage includes: a bag body 1, which is the main structure of the stoma bag and is used to collect body fluids. A visual window 6 is provided on the front surface of the bag body 1, and a transparent plastic film is fixedly installed around it through a fixedly installed fixing ring 5. The internal situation can be observed through the visual window 6, which is convenient for setting the stoma bag on the human body. The end of the bag body 1 is fixedly connected to a sewage outlet 3, which is communicated with the inside of the bag body 1. The body fluids in the bag body 1 can be discharged through the sewage outlet 3. The sealing port 4 provided at the end of the sewage outlet 3 has a certain self-adhesiveness.

[0036] As Figures 2-3 shown, it includes: a first fixing member 7 and a second fixing member 9, both of which are fixedly connected to the surface of the sewage outlet 3, and a plastic sheet 12 is fixedly connected between the first fixing member 7 and the second fixing member 9. The plastic sheet 12 itself has a certain flexibility and a folding groove is provided in the middle. This structure enables the plastic sheet to be repeatedly folded at the grooved place, and the middle of the plastic sheet 12 is thinner and the two ends are thicker. At the same time, the plastic sheet 12 is in contact with but not connected to the surface of the sewage outlet 3. When the plastic sheet 12 is folded through the first fixing member 7 and the second fixing member 9, the folded part of the plastic sheet 12 can assist in blocking the sewage outlet 3. Two hooks 8 are fixedly connected above the first fixing member 7, and a slot 10 is provided on the second fixing member 9. The positions of the hooks 8 and the slot 10 correspond to each other, and the hooks 8 can be inserted into the slot 10. A spring groove 17 is provided in the second fixing member 9, and the spring groove 17 is communicated with the slot 10. A clamping member 14 is slidably installed at the connection between the spring groove 17 and the slot 10. The clamping member 14 can only slide horizontally in the spring groove 17. At the same time, the end of the clamping member 14 is fixedly connected to a bolt 11 on the side surface of the second fixing member 9 through a connecting rod 16. A spring 15 is provided on a part of the surface of the connecting rod 16 located in the spring groove 17, and both ends of the spring 15 are fixedly connected to the clamping member 14 and the inner wall of the spring groove 17. When the hook 8 is inserted into the slot 10, the clamping member 14 is pushed to move to both sides. After the hook 8 penetrates a certain depth, the spring 15 pushes the clamping member 14 to limit the hook 8. Pulling the bolt 11 can release the hook 8 and reset the first fixing member 7.

[0037] As Figure 4 shown, it includes: a fixing plate 19, which is made of plastic support as a whole, has a certain flexibility and is fixedly connected to the center of the back surface of the bag body 1. Connecting members 20 are fixedly connected to both sides of the fixing plate 19, and a bayonet 21 is provided through the connecting members 20. An elastic band 25 is a fixing structure of the stoma bag. Both ends of the elastic band 25 are fixedly connected to a connecting block 23, and a lock 22 is fixedly connected to the connecting block 23. The elastic band 25 can be installed on the bag body 1 through the lock 22 and the bayonet 21, and its length can be adjusted through an adjusting ring 24 provided on the elastic band 25. A stoma chassis 18 is fixedly installed on the back surface of the bag body 1. It is the structure where the stoma bag contacts the human skin, and a thermosensitive hydrocolloid 2 is provided around it, which can make the bag body 1 adhere to the human skin.

[0038] Working principle: The ostomy bag is adhered to the human body through the thermosensitive hydrocolloid 2 on the bag body 1, and then installed in the bayonet 21 on the connecting piece 20 through the buckle 22 on the connecting block 23. The bag body 1 is fixed on the human body by using the elastic band 25. By setting the fixing plate 19 on the bag body 1, fixing the bag body 1 itself on the human body can reduce the influence of gravity on the bonding part. By folding the first fixing piece 7, the hook 8 is inserted into the slot 10, and the clamping piece 14 automatically fixes the hook 8. At the same time, the plastic sheet 12 is folded to assist in blocking the sewage outlet 3. The sewage outlet is blocked by the relatively hard sheet-shaped plastic sheet 12, and the sealing performance is better and the influence of gravity is relatively small compared with the ordinary folding blockage.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
