In an embodiment of the utility model, the chassis body 1 and the annular mounting portion 12 are integrally formed.

[0044] The technical solution of the present invention, by providing the convex portion 11, can make the chassis body 1 better match with the stoma, so that the patient's excrement can smoothly flow into the chassis from the stoma. At the same time, the provision of the convex portion 11 also makes the lower end area of ​​the chassis body 1 larger, thereby making the area of ​​the adhesive sheet 2 covering and attached to the lower end surface of the chassis larger. In this way, the contact area between the adhesive sheet 2 and the skin around the patient's stoma is increased, making the adhesion of the chassis body 1 to the patient's skin more reliable. Furthermore, by providing the belt fixing piece 31 on the chassis body 1, it is convenient to facilitate auxiliary fixation through the belt, thereby improving the fixing reliability of the chassis body 1. Since the two belt fixing pieces 31 are spaced and relatively arranged along the circumference of the chassis body 1, the two belt fixing pieces 31 are pulled in opposite directions. Under the pulling action of the belt, the chassis can be better attached to the patient's skin, thereby improving the adhesion reliability, and solving the problem that the viscosity of the chassis is reduced and easy to fall off after the ostomy bag is used for a long time.

Among them, a connecting ring 2011 is provided at the opening of the bag body 201, and the connecting ring 2011 is sleeved in the annular groove 121, and the outer wall of the connecting ring 2011 is recessed to form a receiving groove 2011a; the clamping ring structure 202 includes a clamping ring 2021, a lock body 2022 and a lock buckle 2023, the clamping ring 2021 is sleeved outside the connecting ring 2011 and is located in the receiving groove 2011a, the clamping ring 2021 is provided with an opening, the lock body 2022 and the lock buckle 2023 are spaced apart on the outer wall surface of the clamping ring 2021, and are located on opposite sides of the opening, and the lock body 2022 and the lock buckle 2023 are used to lock or unlock under the action of external force. The connecting ring 2011 is sleeved in the annular groove 121 formed in the annular mounting portion 12 so that the connecting ring 2011 is relatively fixed to the chassis body 1, and the connecting ring 2011 is limited by the annular groove 121 so that the connecting ring 2011 has a determined installation position on the annular mounting portion 12. As the use time of the ostomy bag 200 increases, the weight of the excrement in the bag body 201 increases continuously. Under the action of gravity, there is a risk of the connecting ring 2011 being pulled off. In order to prevent the connecting ring 2011 from loosening from the chassis body 1, after the connecting ring 2011 is installed in the annular mounting portion 12, the clamping ring structure 202 is further provided outside the connecting ring 2011 to press and fix the connecting ring 2011 in the annular groove 121, thereby improving the connection reliability between the connecting ring 2011 and the annular mounting portion 12.

[0047] In the embodiments of the present invention, please refer to Figure 7The lock body 2022 includes a lock body 20221 and a locking portion 20222. The lock body 20221 is arranged on the outer wall surface of the clamping ring 2021 and is provided with an installation opening extending up and down. The lock body 20221 is provided with a penetration channel. One end opening of the penetration channel is formed on the inner wall surface of the installation opening, and the other end opening is formed on a side surface of the lock body 20221 facing the lock buckle 2023. The locking portion 20222 is arranged on the inner wall surface of the installation opening. The lock buckle 2023 includes a buckle body 20231 arranged on the outer wall surface of the retaining ring 2021, and a matching portion 20232 arranged on the buckle body 20231 facing the lock body 20221, wherein the matching portion 20232 passes through the passing channel and partially extends into the installation port, wherein the locking portion 20222 is used to cooperate with or separate from the matching portion 20232 under the action of external force, so that the lock body 2022 and the lock buckle 2023 are locked or unlocked. After the connecting ring 2011 is sleeved on the outside of the annular mounting portion 12, the matching portion 20232 can pass through the penetration channel to extend into the mounting opening. In this way, under the action of external force, the locking portion 20222 can cooperate with the matching portion 20232 located in the mounting opening, so that the lock body 2022 and the lock buckle 2023 are locked, and then the connecting ring 2011 is pressed and fixed on the annular mounting portion 12, thereby improving the connection reliability between the connecting ring 2011 and the annular mounting portion 12.

[0048] Specifically, in the embodiments of the present invention, please refer to Figure 7, the penetration channel is located on the side of the locking portion 20222 facing the snap ring 2021; the locking portion 20222 includes a deformable arm 20222a arranged on a side wall of the installation port facing the lock body 20221, and the deformable arm 20222a is provided with a groove 20222b on the side facing the snap ring 2021; the matching portion 20232 is provided with a plurality of protrusions 20232a on the side facing away from the snap ring 2021, and in the direction from away from the lock body 20221 to close to the lock body 20221, the plurality of protrusions 20232a are arranged at intervals, and the groove 20222b can be selectively matched with one of the plurality of protrusions 20232a. When the locking portion 20222 cooperates with the matching portion 20232 located in the installation port, the deformable arm 20222a is pulled in a direction away from the retaining ring 2021 by an external force, so that the deformable arm 20222a is deformed, and the matching portion 20232 is moved at the same time so that one of the protrusions 20232a thereon can cooperate with the slot 20222b. After the external force is removed, the deformable arm 20222a restores its deformation to enable the slot 20222b thereon to cooperate with the corresponding protrusion 20232a on the matching portion 20232. In this way, the lock cooperates with the matching portion 20232, that is, the lock body 2022 is locked with the lock buckle 2023, wherein the appropriate protrusion 20232a and the slot 20222b can be selected according to actual needs to adapt to the connecting ring 2011 of different calibers.

[0049] When the locking portion 20222 cooperates with the matching portion 20232 located in the installation port, the deformable arm 20222a must be pulled away from the clamping ring 2021 to deform the deformable arm 20222a to avoid the protrusion 20232a on the matching portion 20232. In order to facilitate the application of external force to deform the deformable arm 20222a, a hand-held portion 20222c is provided on the deformable arm 20222a. In the embodiment of the utility model, please refer to Figure 7 The upper end surface of the deformable arm 20222a is provided with a hand-held portion 20222c, and the hand-held portion 20222c is used for a user to hold. In this way, the hand-held portion 20222c can be held to apply a force to the deformable arm 20222a to deform it, thereby avoiding the protrusion 20232a on the matching portion 20232.

[0050] In the embodiments of the present invention, please refer to Figure 7The upper end surface of the matching portion 20232 is provided with a stopper 20232b, which is located at the end of the matching portion 20232 away from the buckle body 20231, and is used to abut against the inner wall surface of the installation opening to limit the matching. The stopper 20232b abuts against the inner wall surface of the installation opening, so that the end of the matching portion 20232 away from the buckle body 20231 is always located in the installation opening and will not escape from the penetration channel. In this way, when the clamping ring structure 202 is locked, there is no need to perform the penetration operation of the matching portion 20232, which simplifies the operation steps of the matching portion 20232 and the lock buckle 2023, making the use of the clamping ring structure 202 more convenient and simple.

Since the elastic annular protrusion 2011b abuts against the upper side wall of the annular groove 121, the connection between the connecting ring 2011 and the annular mounting portion 12 is made tighter and more reliable, and the elastic annular protrusion 2011b can play a sealing role to prevent leakage at the connection between the connecting ring 2011 and the annular mounting portion 12, thereby improving the sealing performance of the stoma.

[0052] In the embodiments of the present invention, please refer to Figure 6 , the elastic annular protrusion 2011b is arranged to be inclined from top to bottom toward the connecting ring 2011. Since the elastic annular protrusion 2011b is arranged to be inclined from top to bottom toward the connecting ring 2011, during the installation of the connecting ring 2011, the elastic annular protrusion 2011b is deformed and moved closer to the connecting ring 2011 under the push action of the annular mounting portion 12, so as to facilitate the installation of the connecting ring 2011. After the connecting ring 2011 is installed in place, the elastic annular protrusion 2011b recovers its deformation and abuts against the upper side wall of the annular groove 121.

[0053] In the embodiment of the utility model, the bag body 201 is fixed by welding to the connecting ring 2011. The bag body 201 and the connecting ring 2011 are processed separately to reduce the processing difficulty. The two are fixed by welding during assembly to ensure the reliability and sealing of the connection.

[0054] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
