DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] The orientations mentioned in this specification are based on the orientations of the ostomy bag for preventing parastomal hernia of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0027] Embodiment 1

[0028] like Figures 1 to 4 As shown together, the high-drainage ostomy bag includes an abdominal band 1 and a storage bag 3. The abdominal band 1 is used to be worn on the patient's waist and abdomen to achieve fixation, and the storage bag 3 is used to store excrement flowing out of the patient's stoma. The storage bag 3 is detachably connected to the abdominal band 1.

[0029] A chassis 2 is provided on the abdominal band 1, and a storage bag 3 is connected to the stoma through the chassis 2. The outer end of the chassis 2 is an annular protrusion 21, and the annular protrusion 21 is arranged opposite to the stoma. In this embodiment, a through hole is provided on the abdominal band 1, and the chassis 2 includes a base 20, and the base 20 is a silicone plate, which is attached to the inner side of the abdominal band 1. The annular protrusion 21 is an annular cylindrical structure, and one end of the annular protrusion 21 is fixed on the base 20, and the other end passes through the through hole and extends to the outside of the abdominal band 1. A drainage port 30 is provided on one side of the upper part of the storage bag 3, and the drainage port 30 is sleeved with the outer port of the annular protrusion 21 and fixed by a buckle.

[0030] The bottom end surface of the annular protrusion 21 is a concave structure 22, that is, the bottom of the annular protrusion forms a notch-shaped structure, which makes the excrement flow smoother, the drainage faster, and more convenient to use.

[0031] When in use, the base is installed on the belly belt 1 , and then the belly belt 1 is worn on the patient so that the base faces the stoma, and then the storage bag 3 is installed on the chassis 2 .

[0032] When the storage bag 3 is full, it can be removed and replaced with a new storage bag 3. After the treatment is completed, the abdominal belt 1 is removed, and the base and the connected storage bag 3 are removed from the abdominal belt 1, and the abdominal belt 1 can be reused.

[0033] Furthermore, a one-way exhaust port 31 is provided on the upper portion of the storage bag 3. In the present embodiment, the one-way exhaust port 31 is preferably a one-way elastic exhaust sheet for exhausting and relieving pressure of the storage bag 3. In other embodiments, the one-way exhaust port 31 may also adopt a one-way valve.

[0034] Furthermore, the belly band 1 is provided with a plurality of exhaust holes, which can dissipate heat and ventilate in time, thereby improving the wearing comfort.

[0035] Embodiment 2

[0036] The difference between this embodiment and the first embodiment is that Figure 5As shown, a fixed tube 10 is fixedly connected to the outside of the abdominal band 1, a sealing ring is provided on the inner wall of the fixed tube 10, the fixed tube 10 is coaxially sealed and plug-in connected with the annular protrusion 21, a rotating ring 11 is provided on the outside of the fixed tube 10, a first annular groove is provided on the outer side of the rotating ring 11, and a first annular protrusion is provided on the inner wall of the drainage port 30 to fit with the first annular groove. The storage bag 3 is directly connected to the rotating ring 11 and can rotate synchronously with the rotating ring 11 around the fixed tube 10. When the patient's body posture changes, the storage bag 3 is always kept in a vertical state under the action of gravity, avoiding the backflow of excrement.

[0037] Embodiment 3

[0038] The difference between this embodiment and the first embodiment is that Figure 6 As shown, the annular raised portion 21 includes a first ring cylinder 210, which is fixed to the base 20, and the first ring cylinder 210 is coaxially rotatably connected to the second ring cylinder 211. The first ring cylinder 210 and the second ring cylinder 211 are coaxially plugged into the opposite ends, and a rotating sealing ring 212 is provided at the plug-in position, and the concave structure 22 is provided on the bottom outer end surface of the second ring cylinder 211, and a second annular groove is provided on the outer side of the second ring cylinder 211, and a second annular protrusion that is engaged with the second annular groove is provided on the inner wall of the drainage port, so that the storage bag 3 is directly connected to the second ring cylinder 211, so that the second ring cylinder 211 and the storage bag 3 can rotate synchronously around the first ring cylinder 210, which ensures that the storage bag 3 is always vertical when the patient's body posture changes, and at the same time, the concave structure 22 is always located at the lower position, so that the diversion is always smooth.

[0039] Furthermore, a rubber layer is provided on the inner side of the annular groove, so that after the second annular protrusion is engaged with the second annular groove, the elastic action of the rubber layer increases the friction between the second annular protrusion and the second annular groove, thereby preventing the second ring tube 211 and the storage bag 3 from rotating relative to each other.

[0040] Embodiment 4

[0041] The difference between this embodiment and the first embodiment is that Figure 7 As shown, a drainage port 32 is provided at the bottom of the storage bag 3, and an end cover 33 is provided on the inner side of the storage bag 3. The end cover 33 is buckled with the inner end of the annular protrusion 21. When the space of the storage bag 3 is less than 60%, the end cover 33 is pressed onto the annular protrusion 21 to close the channel of the annular protrusion 21, and then the drainage port 32 is opened and the storage bag 3 is squeezed to squeeze out the excrement, so that the storage bag 3 can be reused within a certain period, thereby reducing costs and reducing waste output.

[0042] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
