[0034] The utility model provides a locking member 100, which is applicable to an ostomy bag 1000, so that the ostomy bag 1000 can be connected and fixed with a chassis connecting member through the locking member 100, so that the ostomy bag 1000 can be more convenient for ostomy patients to use.

[0035] Specifically, see Figures 1 to 3 The locking member 100 includes a locking ring 1, a first locking structure 2 and a second locking structure 3. The locking ring 1 is arranged in a non-closed loop and has a notch formed on one side. The locking ring 1 has a first end and a second end forming the notch; the first locking structure 2 is arranged at the first end of the locking ring 1; the second locking structure 3 is arranged at the second end of the locking ring 1; the locking ring 1 has elastic deformability. When the locking ring 1 is deformed by an external force, the first end of the locking ring 1 and the second end of the locking ring 1 can be driven to approach each other, and the first locking structure 2 and the second locking structure 3 can be driven to lock and cooperate to be in a first locking state; when the first locking structure 2 and the second locking structure 3 are unlocked, the first end of the locking ring 1 and the second end of the locking ring 1 can be separated from each other under the action of the elastic restoring force of the locking ring 1 to be in a separated state.

[0036] The locking member 100 provided by the utility model can firmly lock the sealing ring of the ostomy bag with the chassis base through the locking ring 1. This method adopts a spring arm type locking buckle, which is locked by the first locking structure 2 and the second locking structure 3, so that the locking member can be fixed in the first locking state, so that the locking member 100 can be locked with the chassis, so that when the locking member 100 is suitable for the ostomy bag 1000, the ostomy bag 1000 can be reliably fixed on the chassis, not easy to fall off, and after multiple disassembly and assembly, the first connection structure and the second connection structure are not easy to fail to connect, and the service life of the ostomy bag 1000 is longer; and when the ostomy bag 1000 needs to be disassembled, the first locking structure 2 and the second locking structure 3 can be separated, so that the locking ring 1 and the chassis are unlocked, and the ostomy bag 1000 can be disassembled from the chassis, and the disassembly and assembly of the ostomy band are easy to operate, and patients of different ages can easily operate it, and patients can use it more easily. In addition, this structure has a lower precision requirement for size, which makes it easier to improve the yield rate and is conducive to reducing production costs.

[0037] Preferably, the locking ring 1 is provided in a circular ring shape to fit the stoma of the patient. The locking ring 1 can be made of a plastic material and has a certain elasticity, so that when an external force is pressed on the locking ring 1, the first end and the second end of the locking ring 1 can be close to each other to reduce the gap, so that the locking ring 1 can be locked with the convex part on the chassis, or the first end and the second end can be away from each other to expand the gap, so that the locking ring 1 can be better sleeved on the chassis.

[0038] Among them, Figure 1 As shown in the figure, the locking ring 1 may include a locking bottom ring 11, and a locking side ring 12 arranged around the outer peripheral side of the locking bottom ring 11, and the first locking structure 2 and the second locking structure 3 are both arranged on the outer side of the locking side ring 12, and are connected to the inlet side of the ostomy bag 1000 through the locking bottom ring 11, so that the contact area is larger and it is more convenient to fix the locking member 100 on the bag body 200.

[0039] Moreover, an annular convex rib 111 is protruded from the locking bottom ring 11 to increase the strength of the locking bottom ring 11. When connected to the bag body 200, a seal can be provided at the convex rib to ensure better sealing at the inlet.

[0040] For the first locking structure 2, combined with Figure 1 and Figure 2As shown, the first locking structure 2 includes a first locking block 21 protruding from the first end of the locking ring 1, and a locking groove 22 formed on the first locking block 21; the second locking structure 3 includes a second locking block 31 protruding from the second end of the locking ring 1, and a first locking protrusion 32 protruding from the locking block, the first locking protrusion 32 and the locking groove 22 are snap-fitted to fix the locking ring 1 in the first locking state, so that the locking ring 1 can be fixedly connected to the chassis.

[0041] Furthermore, the locking groove 22 has a first opening 23 disposed toward the second end of the locking ring 1, and a second opening 24 disposed on a side wall disposed opposite to the locking ring 1. The second locking block 31 can extend from the first opening 23 into the locking groove 22, and the first locking protrusion 32 can be engaged with the side wall of the second opening 24. External force acts on the locking ring 1, so that the second end and the first end are close to each other, so that the second locking block 31 can extend from the first opening 23 into the locking groove 22. When the second locking block 31 moves into place, the first locking protrusion 32 can be engaged with the side wall of the second opening 24, so that the locking ring 1 is fixed in the first locking state, so that the ostomy bag 1000 can be reliably connected to the chassis.

[0042] Furthermore, combined with Figure 1 and Figure 2 As shown, the second locking block 31 includes a locking block body 311 and an elastic arm 312 disposed on one side of the locking block body 311. The elastic arm 312 has a connecting end and a free end that are oppositely disposed. The connecting end is connected to the front end of the locking block body 311. The free end of the elastic arm 312 extends backward from the front end of the locking block body 311. The first locking protrusion 32 is disposed on the outer side of the elastic arm 312. When the first end and the second end of the locking ring 1 are close to each other, the second locking block 31 can extend from the first opening 23 into the locking groove 22, so that the first locking protrusion 32 on the elastic arm 312 is clamped on the side wall of the second opening 24, so that the locking ring 1 is in the first locking state, and the elastic wall is in a naturally stretched state at this time.

[0043] The first locking protrusion 32 is arranged near the front end of the elastic arm 312, and the rear end of the elastic arm 312 is also provided with an adjusting portion 4. The adjusting portion 4 can be acted upon by an external force, so that the elastic arm 312 moves toward the direction close to the locking block body 311, so that the first locking protrusion 32 can be disengaged from the second opening 24, so that the first locking protrusion 32 is separated from the second opening 24, so that under the action of the elastic restoring force of the locking ring 1, the first locking structure 2 and the second locking structure 3 can be driven away from each other, so that the locking ring 1 is separated from the chassis, so that the ostomy bag 1000 can be removed from the chassis. It should be noted that the front end of the elastic arm 312 here refers to the end of the elastic arm 312 close to the first end of the locking ring 1, and the rear end refers to the end facing away from the first end, so that the first locking protrusion 32 can first extend into the locking groove 22, so as to first reach the second opening 24, so as to quickly lock with the second opening 24.

[0044] Furthermore, a chamfer is provided at the front end of the second locking block 31 , so that the second locking block 31 can be inserted more smoothly into the locking groove 22 , thereby making the locking operation more worry-free.

[0045] Preferably, the adjusting portion 4 is configured as an adjusting boss, and the patient presses the adjusting boss to move the elastic arm 312 , thereby driving the first locking protrusion 32 to move to disengage from the second opening 24 , thereby conveniently taking out the ostomy bag 1000 .

[0046] Moreover, if Figure 3 As shown in the figure, a stop portion 33 is also protruded from the second locking block 31. When the first locking protrusion 32 and the locking groove 22 are locked and matched, the stop portion 33 abuts against the first opening 23 of the locking groove 22 to limit the depth of the second locking block 31 extending into the locking groove 22, thereby ensuring that the first locking protrusion 32 and the second opening 24 can be better relative and engaged.

[0047] In addition, a third opening 25 is provided on the side wall of the locking groove 22, and the third opening 25 is located on the side wall adjacent to the first opening 23; a second locking protrusion 34 is also protruded from the second locking block 31. When the locking ring 1 switches from the first locking state to the separation state, the second locking protrusion 34 can be snapped onto the side wall of the third opening 25 to fix the locking ring 1 in the second locking state, so that the second locking block 31 does not completely escape from the locking groove 22. Therefore, the locking member 100 is still in a full ring state, so that the strength is better, and the locking member 100 can be unlocked while the notch of the locking member 100 is not easy to break and fold, which can better protect the locking member 100.

[0048] The utility model also provides an ostomy bag 1000, such as Figure 4As shown in , the ostomy bag 1000 includes a bag body 200 and the above-mentioned locking member 100. The inlet of the ostomy bag 1000 is suitable for being connected to the stoma of the patient, and the excrement discharged by the patient can enter the inner cavity of the bag body 200 from the inlet for storage. The locking ring 1 of the locking member 100 is sleeved at the inlet of the bag body 200. The ostomy bag 1000 can be fixed to the chassis through the locking member 100, so that the fixation of the ostomy bag 1000 is more reliable, and the patient is more comfortable when using it. In addition, the ostomy bag 1000 is easy to disassemble and assemble, and the cleanliness of the ostomy bag 1000 can be maintained. The patient is not prone to odor when using it, and the use is more comfortable and the user experience is better.

[0049] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
